+ * Each BOARD consists of COMPONENTs and the BOARD structure has 
+ * pointers (offsets) to its COMPONENT structure.
+ * The COMPONENT structure has version info, size and speed info, revision,
+ * error info and the NIC info. This structure can accommodate any
+ * BOARD with arbitrary COMPONENT composition.
+ *
+ * The ERRORINFO part of each BOARD has error information
+ * that describes errors about the BOARD itself. It also has flags to
+ * indicate the COMPONENT(s) on the board that have errors. The error 
+ * information specific to the COMPONENT is present in the respective 
+ * COMPONENT structure.
+ *
+ * The ERRORINFO structure is also treated like a COMPONENT, ie. the 
+ * BOARD has pointers(offset) to the ERRORINFO structure. The rboard
+ * structure also has a pointer to the ERRORINFO structure. This is 
+ * the place to store ERRORINFO about a REMOTE NODE, if the HUB on
+ * that NODE is not working or if the REMOTE MEMORY is BAD. In cases where 
+ * only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can
+ * be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info 
+ * which is present on the REMOTE NODE.(TBD)
+ * REMOTE ERRINFO can be stored on any of the nearest nodes 
+ * or on all the nearest nodes.(TBD)
+ * Like BOARD structures, REMOTE ERRINFO structures can be built locally
+ * using the rboard errinfo pointer.
+ *
+ * In order to get useful information from this Data organization, a set of
+ * interface routines are provided (TBD). The important thing to remember while
+ * manipulating the structures, is that, the NODE number information should
+ * be used. If the NODE is non-zero (remote) then each offset should
+ * be added to the REMOTE BASE ADDR else it should be added to the LOCAL BASE ADDR. 
+ * This includes offsets for BOARDS, COMPONENTS and ERRORINFO.
+ * 
+ * Note that these structures do not provide much info about connectivity.
+ * That info will be part of HWGRAPH, which is an extension of the cfg_t
+ * data structure. (ref IP27prom/cfg.h) It has to be extended to include
+ * the IO part of the Network(TBD).
+ *
+ * The data structures below define the above concepts.

+ * PIC AS DEVICE ZERO
+ * ------------------
+ *
+ * PIC handles PCI/X busses.  PCI/X requires that the 'bridge' (i.e. PIC)
+ * be designated as 'device 0'.   That is a departure from earlier SGI
+ * PCI bridges.  Because of that we use config space 1 to access the
+ * config space of the first actual PCI device on the bus.
+ * Here's what the PIC manual says:
+ *
+ *     The current PCI-X bus specification now defines that the parent
+ *     hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC
+ *     reduced the total number of devices from 8 to 4 and removed the
+ *     device registers and windows, now only supporting devices 0,1,2, and
+ *     3. PIC did leave all 8 configuration space windows. The reason was
+ *     there was nothing to gain by removing them. Here in lies the problem.
+ *     The device numbering we do using 0 through 3 is unrelated to the device
+ *     numbering which PCI-X requires in configuration space. In the past we
+ *     correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc.
+ *     PCI-X requires we start a 1, not 0 and currently the PX brick
+ *     does associate our:
+ *
+ *         device 0 with configuration space window 1,
+ *         device 1 with configuration space window 2,
+ *         device 2 with configuration space window 3,
+ *         device 3 with configuration space window 4.
+ *
+ * The net effect is that all config space access are off-by-one with
+ * relation to other per-slot accesses on the PIC.
+ * Here is a table that shows some of that:
+ *
+ *                               Internal Slot#
+ *           |
+ *           |     0         1        2         3

+ *           |

+ * Description:  This register's value is a bit vector that guards      *
+ * access to local registers within the II as well as to external       *
+ * Crosstalk widgets. Each bit in the register corresponds to a         *
+ * particular region in the system; a region consists of one, two or    *
+ * four nodes (depending on the value of the REGION_SIZE field in the   *
+ * LB_REV_ID register, which is documented in Section 8.3.1.1). The     *
+ * protection provided by this register applies to PIO read             *
+ * operations as well as PIO write operations. The II will perform a    *
+ * PIO read or write request only if the bit for the requestor's        *
+ * region is set; otherwise, the II will not perform the requested      *
+ * operation and will return an error response. When a PIO read or      *
+ * write request targets an external Crosstalk widget, then not only    *
+ * must the bit for the requestor's region be set in the ILAPR, but     *
+ * also the target widget's bit in the IOWA register must be set in     *
+ * order for the II to perform the requested operation; otherwise,      *
+ * the II will return an error response. Hence, the protection          *
+ * provided by the IOWA register supplements the protection provided    *
+ * by the ILAPR for requests that target external Crosstalk widgets.    *
+ * This register itself can be accessed only by the nodes whose         *
+ * region ID bits are enabled in this same register. It can also be     *
+ * accessed through the IAlias space by the local processors.           *

+ *  Definitions of terms (these definitions are for IA64 ONLY. Other architectures
+ *  use cpuid/cpunum quite defferently):
+ *
+ *	   CPUID - a number in range of 0..NR_CPUS-1 that uniquely identifies
+ *		the cpu. The value cpuid has no significance on IA64 other than
+ *		the boot cpu is 0.
+ *			smp_processor_id() returns the cpuid of the current cpu.
+ *
+ * 	   CPU_PHYSICAL_ID (also known as HARD_PROCESSOR_ID)
+ *		This is the same as 31:24 of the processor LID register
+ *			hard_smp_processor_id()- cpu_physical_id of current processor
+ *			cpu_physical_id(cpuid) - convert a <cpuid> to a <physical_cpuid>
+ *			cpu_logical_id(phy_id) - convert a <physical_cpuid> to a <cpuid> 
+ *				* not real efficient - don't use in perf critical code
+ *
+ *         SLICE - a number in the range of 0 - 3 (typically) that represents the
+ *		cpu number on a brick.
+ *
+ *	   SUBNODE - (almost obsolete) the number of the FSB that a cpu is
+ *		connected to. This is also the same as the PI number. Usually 0 or 1.
+ *
+ *	NOTE!!!: the value of the bits in the cpu physical id (SAPICid or LID) of a cpu has no 
+ *	significance. The SAPIC id (LID) is a 16-bit cookie that has meaning only to the PROM.
+ *
+ *
+ * The macros convert between cpu physical ids & slice/nasid/cnodeid.

+ * DMA space
+ *
+ * The CA aperature (ie. bus address range) mapped by the GART is segmented into
+ * two parts.  The lower portion of the aperature is used for mapping 32 bit
+ * PCI addresses which are managed by the dma interfaces in this file.  The
+ * upper poprtion of the aperature is used for mapping 48 bit AGP addresses.
+ * The AGP portion of the aperature is managed by the agpgart_be.c driver
+ * in drivers/linux/agp.  There are ca-specific hooks in that driver to
+ * manipulate the gart, but management of the AGP portion of the aperature
+ * is the responsibility of that driver.
+ *
+ * CA allows three main types of DMA mapping:
+ *
+ * PCI 64-bit	Managed by this driver
+ * PCI 32-bit 	Managed by this driver
+ * AGP 48-bit	Managed by hooks in the /dev/agpgart driver
+ *
+ * All of the above can optionally be remapped through the GART.  The following
+ * table lists the combinations of addressing types and GART remapping that
+ * is currently supported by the driver (h/w supports all, s/w limits this):
+ *
+ *		PCI64		PCI32		AGP48
+ * GART		no		yes		yes
+ * Direct	yes		yes		no
+ *
+ * GART remapping of PCI64 is not done because there is no need to.  The
+ * 64 bit PCI address holds all of the information necessary to target any
+ * memory in the system.
+ *
+ * AGP48 is always mapped through the GART.  Management of the AGP48 portion
+ * of the aperature is the responsibility of code in the agpgart_be driver.
+ *
+ * The non-64 bit bus address space will currently be partitioned like this:
+ *
+ *	0xffff_ffff_ffff	+--------
+ *				| AGP48 direct
+ *				| Space managed by this driver
+ *	CA_AGP_DIRECT_BASE	+--------
+ *				| AGP GART mapped (gfx aperature)
+ *				| Space managed by /dev/agpgart driver
+ *				| This range is exposed to the agpgart
+ * 				| driver as the "graphics aperature"
+ *	CA_AGP_MAPPED_BASE	+-----
+ *				| PCI GART mapped
+ *				| Space managed by this driver		
+ *	CA_PCI32_MAPPED_BASE	+----
+ *				| PCI32 direct
+ *				| Space managed by this driver
+ *	0xC000_0000		+--------
+ *	(CA_PCI32_DIRECT_BASE)
+ *
+ * The bus address range CA_PCI32_MAPPED_BASE through CA_AGP_DIRECT_BASE
+ * is what we call the CA aperature.  Addresses falling in this range will
+ * be remapped using the GART.
+ *
+ * The bus address range CA_AGP_MAPPED_BASE through CA_AGP_DIRECT_BASE
+ * is what we call the graphics aperature.  This is a subset of the CA
+ * aperature and is under the control of the agpgart_be driver.
+ *
+ * CA_PCI32_MAPPED_BASE, CA_AGP_MAPPED_BASE, and CA_AGP_DIRECT_BASE are
+ * somewhat arbitrary values.  The known constraints on choosing these is:
+ *
+ * 1)  CA_AGP_DIRECT_BASE-CA_PCI32_MAPPED_BASE+1 (the CA aperature size)
+ *     must be one of the values supported by the ca_gart_aperature register.
+ *     Currently valid values are: 4MB through 4096MB in powers of 2 increments
+ *
+ * 2)  CA_AGP_DIRECT_BASE-CA_AGP_MAPPED_BASE+1 (the gfx aperature size)
+ *     must be in MB units since that's what the agpgart driver assumes.
+ */
+
+/*
+ * Define Bus DMA ranges.  These are configurable (see constraints above)
+ * and will probably need tuning based on experience.
+ */
+
+
+/*
+ * 11/24/03
+ * CA has an addressing glitch w.r.t. PCI direct 32 bit DMA that makes it
+ * generally unusable.  The problem is that for PCI direct 32 
+ * DMA's, all 32 bits of the bus address are used to form the lower 32 bits
+ * of the coretalk address, and coretalk bits 38:32 come from a register.
+ * Since only PCI bus addresses 0xC0000000-0xFFFFFFFF (1GB) are available
+ * for DMA (the rest is allocated to PIO), host node addresses need to be
+ * such that their lower 32 bits fall in the 0xC0000000-0xffffffff range
+ * as well.  So there can be no PCI32 direct DMA below 3GB!!  For this
+ * reason we set the CA_PCI32_DIRECT_SIZE to 0 which essentially makes
+ * tioca_dma_direct32() a noop but preserves the code flow should this issue
+ * be fixed in a respin.
+ *
+ * For now, all PCI32 DMA's must be mapped through the GART.

+ * This file defines various macros to transfer memory areas across
+ * the user/kernel boundary.  This needs to be done carefully because
+ * this code is executed in kernel mode and uses user-specified
+ * addresses.  Thus, we need to be careful not to let the user to
+ * trick us into accessing kernel memory that would normally be
+ * inaccessible.  This code is also fairly performance sensitive,
+ * so we want to spend as little time doing safety checks as
+ * possible.
+ *
+ * To make matters a bit more interesting, these macros sometimes also
+ * called from within the kernel itself, in which case the address
+ * validity check must be skipped.  The get_fs() macro tells us what
+ * to do: if get_fs()==USER_DS, checking is performed, if
+ * get_fs()==KERNEL_DS, checking is bypassed.
+ *
+ * Note that even if the memory area specified by the user is in a
+ * valid address range, it is still possible that we'll get a page
+ * fault while accessing it.  This is handled by filling out an
+ * exception handler fixup entry for each instruction that has the
+ * potential to fault.  When such a fault occurs, the page fault
+ * handler checks to see whether the faulting instruction has a fixup
+ * associated and, if so, sets r8 to -EFAULT and clears r9 to 0 and
+ * then resumes execution at the continuation point.

+ * follows:
+ *
+ *  upage: 1 page consisting of a user struct that tells gdb
+ *	what is present in the file.  Directly after this is a
+ *	copy of the task_struct, which is currently not used by gdb,
+ *	but it may come in handy at some point.  All of the registers
+ *	are stored as part of the upage.  The upage should always be
+ *	only one page long.
+ *  data: The data segment follows next.  We use current->end_text to
+ *	current->brk to pick up all of the user variables, plus any memory
+ *	that may have been sbrk'ed.  No attempt is made to determine if a
+ *	page is demand-zero or if a page is totally unused, we just cover
+ *	the entire range.  All of the addresses are rounded in such a way
+ *	that an integral number of pages is written.
+ *  stack: We need the stack information in order to get a meaningful
+ *	backtrace.  We need to write the data from usp to
+ *	current->start_stack, so we round each of these in order to be able
+ *	to write an integer number of pages.

+ * Addressing Terminology
+ *
+ *	M       - The low M bits of a physical address represent the offset
+ *		  into the blade local memory. RAM memory on a blade is physically
+ *		  contiguous (although various IO spaces may punch holes in
+ *		  it)..
+ *
+ * 	N	- Number of bits in the node portion of a socket physical
+ * 		  address.
+ *
+ * 	NASID   - network ID of a router, Mbrick or Cbrick. Nasid values of
+ * 	 	  routers always have low bit of 1, C/MBricks have low bit
+ * 		  equal to 0. Most addressing macros that target UV hub chips
+ * 		  right shift the NASID by 1 to exclude the always-zero bit.
+ * 		  NASIDs contain up to 15 bits.
+ *
+ *	GNODE   - NASID right shifted by 1 bit. Most mmrs contain gnodes instead
+ *		  of nasids.
+ *
+ * 	PNODE   - the low N bits of the GNODE. The PNODE is the most useful variant
+ * 		  of the nasid for socket usage.
+ *
+ *
+ *  NumaLink Global Physical Address Format:
+ *  +--------------------------------+---------------------+
+ *  |00..000|      GNODE             |      NodeOffset     |
+ *  +--------------------------------+---------------------+
+ *          |<-------53 - M bits --->|<--------M bits ----->
+ *
+ *	M - number of node offset bits (35 .. 40)
+ *
+ *
+ *  Memory/UV-HUB Processor Socket Address Format:
+ *  +----------------+---------------+---------------------+
+ *  |00..000000000000|   PNODE       |      NodeOffset     |
+ *  +----------------+---------------+---------------------+
+ *                   <--- N bits --->|<--------M bits ----->
+ *
+ *	M - number of node offset bits (35 .. 40)
+ *	N - number of PNODE bits (0 .. 10)
+ *
+ *		Note: M + N cannot currently exceed 44 (x86_64) or 46 (IA64).
+ *		The actual values are configuration dependent and are set at
+ *		boot time. M & N values are set by the hardware/BIOS at boot.

- *  To enable debugger support, two things need to happen.  One, a
- *  call to set_debug_traps() is necessary in order to allow any breakpoints
- *  or error conditions to be properly intercepted and reported to gdb.
- *  Two, a breakpoint needs to be generated to begin communication.  This
- *  is most easily accomplished by a call to breakpoint().  Breakpoint()
- *  simulates a breakpoint by executing a BREAK instruction.
- *
- *
- *    The following gdb commands are supported:
- *
- * command          function                               Return value
- *
- *    g             return the value of the CPU registers  hex data or ENN
- *    G             set the value of the CPU registers     OK or ENN
- *
- *    mAA..AA,LLLL  Read LLLL bytes at address AA..AA      hex data or ENN
- *    MAA..AA,LLLL: Write LLLL bytes at address AA.AA      OK or ENN
- *
- *    c             Resume at current address              SNN   ( signal NN)
- *    cAA..AA       Continue at address AA..AA             SNN
- *
- *    s             Step one instruction                   SNN
- *    sAA..AA       Step one instruction from AA..AA       SNN
- *
- *    k             kill
- *
- *    ?             What was the last sigval ?             SNN   (signal NN)
- *
- *    bBB..BB	    Set baud rate to BB..BB		   OK or BNN, then sets
- *							   baud rate
- *
- * All commands and responses are sent with a packet which includes a
- * checksum.  A packet consists of
- *
- * $<packet info>#<checksum>.
- *
- * where
- * <packet info> :: <characters representing the command or response>
- * <checksum>    :: < two hex digits computed as modulo 256 sum of <packetinfo>>
- *
- * When a packet is received, it is first acknowledged with either '+' or '-'.
- * '+' indicates a successful transfer.  '-' indicates a failed transfer.
- *
- * Example:
- *
- * Host:                  Reply:
- * $m0,10#2a               +$00010203040506070809101112131415#42
- *
- *
- *  ==============
- *  MORE EXAMPLES:
- *  ==============
- *
- *  For reference -- the following are the steps that one
- *  company took (RidgeRun Inc) to get remote gdb debugging
- *  going. In this scenario the host machine was a PC and the
- *  target platform was a Galileo EVB64120A MIPS evaluation
- *  board.
- *
- *  Step 1:
- *  First download gdb-5.0.tar.gz from the internet.
- *  and then build/install the package.
- *
- *  Example:
- *    $ tar zxf gdb-5.0.tar.gz
- *    $ cd gdb-5.0
- *    $ ./configure --target=mips-linux-elf
- *    $ make
- *    $ install
- *    $ which mips-linux-elf-gdb
- *    /usr/local/bin/mips-linux-elf-gdb
- *
- *  Step 2:
- *  Configure linux for remote debugging and build it.
- *
- *  Example:
- *    $ cd ~/linux
- *    $ make menuconfig <go to "Kernel Hacking" and turn on remote debugging>
- *    $ make
- *
- *  Step 3:
- *  Download the kernel to the remote target and start
- *  the kernel running. It will promptly halt and wait
- *  for the host gdb session to connect. It does this
- *  since the "Kernel Hacking" option has defined
- *  CONFIG_KGDB which in turn enables your calls
- *  to:
- *     set_debug_traps();
- *     breakpoint();
- *
- *  Step 4:
- *  Start the gdb session on the host.
- *
- *  Example:
- *    $ mips-linux-elf-gdb vmlinux
- *    (gdb) set remotebaud 115200
- *    (gdb) target remote /dev/ttyS1
- *    ...at this point you are connected to
- *       the remote target and can use gdb
- *       in the normal fasion. Setting
- *       breakpoints, single stepping,
- *       printing variables, etc.

+ * PowerPC atomic bit operations.
+ *
+ * Merged version by David Gibson <david@gibson.dropbear.id.au>.
+ * Based on ppc64 versions by: Dave Engebretsen, Todd Inglett, Don
+ * Reed, Pat McCarthy, Peter Bergner, Anton Blanchard.  They
+ * originally took it from the ppc32 code.
+ *
+ * Within a word, bits are numbered LSB first.  Lot's of places make
+ * this assumption by directly testing bits with (val & (1<<nr)).
+ * This can cause confusion for large (> 1 word) bitmaps on a
+ * big-endian system because, unlike little endian, the number of each
+ * bit depends on the word size.
+ *
+ * The bitop functions are defined to work on unsigned longs, so for a
+ * ppc64 system the bits end up numbered:
+ *   |63..............0|127............64|191...........128|255...........196|
+ * and on ppc32:
+ *   |31.....0|63....31|95....64|127...96|159..128|191..160|223..192|255..224|
+ *
+ * There are a few little-endian macros used mostly for filesystem
+ * bitmaps, these work on similar bit arrays layouts, but
+ * byte-oriented:
+ *   |7...0|15...8|23...16|31...24|39...32|47...40|55...48|63...56|
+ *
+ * The main difference is that bit 3-5 (64b) or 3-4 (32b) in the bit
+ * number field needs to be reversed compared to the big-endian bit
+ * fields. This can be achieved by XOR with 0x38 (64b) or 0x18 (32b).
+ *

+ *
+ * On PReP, DMA transfers are limited to the lower 16MB of _physical_ memory.
+ * On CHRP, the W83C553F (and VLSI Tollgate?) support full 32 bit addressing.
+ * Note that addresses loaded into registers must be _physical_ addresses,
+ * not logical addresses (which may differ if paging is active).
+ *
+ *  Address mapping for channels 0-3:
+ *
+ *   A23 ... A16 A15 ... A8  A7 ... A0    (Physical addresses)
+ *    |  ...  |   |  ... |   |  ... |
+ *    |  ...  |   |  ... |   |  ... |
+ *    |  ...  |   |  ... |   |  ... |
+ *   P7  ...  P0  A7 ... A0  A7 ... A0
+ * |    Page    | Addr MSB | Addr LSB |   (DMA registers)
+ *
+ *  Address mapping for channels 5-7:
+ *
+ *   A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0    (Physical addresses)
+ *    |  ...  |   \   \   ... \  \  \  ... \  \
+ *    |  ...  |    \   \   ... \  \  \  ... \  (not used)
+ *    |  ...  |     \   \   ... \  \  \  ... \
+ *   P7  ...  P1 (0) A7 A6  ... A0 A7 A6 ... A0
+ * |      Page      |  Addr MSB   |  Addr LSB  |   (DMA registers)
+ *
+ * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
+ * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
+ * the hardware level, so odd-byte transfers aren't possible).
+ *
+ * Transfer count (_not # bytes_) is limited to 64K, represented as actual
+ * count - 1 : 64K => 0xFFFF, 1 => 0x0000.  Thus, count is always 1 or more,
+ * and up to 128K bytes may be transferred on channels 5-7 in one operation.

+ * ioremap     -   map bus memory into CPU space
+ * @address:   bus address of the memory

+ *
+ * ioremap performs a platform specific sequence of operations to
+ * make bus memory CPU accessible via the readb/readw/readl/writeb/
+ * writew/writel functions and the other mmio helpers. The returned
+ * address is not guaranteed to be usable directly as a virtual
+ * address.
+ *
+ * We provide a few variations of it:
+ *
+ * * ioremap is the standard one and provides non-cacheable guarded mappings
+ *   and can be hooked by the platform via ppc_md
+ *
+ * * ioremap_flags allows to specify the page flags as an argument and can
+ *   also be hooked by the platform via ppc_md. ioremap_prot is the exact
+ *   same thing as ioremap_flags.
+ *
+ * * ioremap_nocache is identical to ioremap
+ *
+ * * iounmap undoes such a mapping and can be hooked
+ *
+ * * __ioremap_at (and the pending __iounmap_at) are low level functions to
+ *   create hand-made mappings for use only by the PCI code and cannot
+ *   currently be hooked. Must be page aligned.
+ *
+ * * __ioremap is the low level implementation used by ioremap and
+ *   ioremap_flags and cannot be hooked (but can be used by a hook on one
+ *   of the previous ones)
+ *
+ * * __iounmap, is the low level implementation used by iounmap and cannot

+ *
+ * The two forms are distinguishable because the top bit is 0 for user
+ * addresses, whereas the top two bits are 1 for kernel addresses.
+ * Proto-VSIDs with the top two bits equal to 0b10 are reserved for
+ * now.
+ *
+ * The proto-VSIDs are then scrambled into real VSIDs with the
+ * multiplicative hash:
+ *
+ *	VSID = (proto-VSID * VSID_MULTIPLIER) % VSID_MODULUS
+ *	where	VSID_MULTIPLIER = 268435399 = 0xFFFFFC7
+ *		VSID_MODULUS = 2^36-1 = 0xFFFFFFFFF
+ *

+ * 0xFFFFFFFFF, so both proto-VSID and actual VSID 0xFFFFFFFFF are
+ * reserved.  VSID_MULTIPLIER is prime, so in particular it is
+ * co-prime to VSID_MODULUS, making this a 1:1 scrambling function.
+ * Because the modulus is 2^n-1 we can compute it efficiently without
+ * a divide or extra multiply (see below).
+ *
+ * This scheme has several advantages over older methods:
+ *
+ * 	- We have VSIDs allocated for every kernel address
+ * (i.e. everything above 0xC000000000000000), except the very top
+ * segment, which simplifies several things.
+ *
+ * 	- We allow for 15 significant bits of ESID and 20 bits of
+ * context for user addresses.  i.e. 8T (43 bits) of address space for
+ * up to 1M contexts (although the page table structure and context
+ * allocation will need changes to take advantage of this).
+ *
+ * 	- The scramble function gives robust scattering in the hash
+ * table (at least based on some initial results).  The previous
+ * method was more susceptible to pathological cases giving excessive
+ * hash collisions.

+ * The PowerPC MPC8xx uses a TLB with hardware assisted, software tablewalk.

+ * Mx_CTR.PPCS = 0, and MD_CTR.TWAM = 1.  The level 2 descriptor has
+ * additional page protection (when Mx_CTR.PPCS = 1) that allows TLB hit
+ * based upon user/super access.  The TLB does not have accessed nor write
+ * protect.  We assume that if the TLB get loaded with an entry it is
+ * accessed, and overload the changed bit for write protect.  We use
+ * two bits in the software pte that are supposed to be set to zero in
+ * the TLB entry (24 and 25) for these indicators.  Although the level 1
+ * descriptor contains the guarded and writethrough/copyback bits, we can
+ * set these at the page level since they get copied from the Mx_TWC
+ * register when the TLB entry is loaded.  We will use bit 27 for guard, since
+ * that is where it exists in the MD_TWC, and bit 26 for writethrough.
+ * These will get masked from the level 2 descriptor at TLB load time, and
+ * copied to the MD_TWC before it gets loaded.
+ * Large page sizes added.  We currently support two sizes, 4K and 8M.
+ * This also allows a TLB hander optimization because we can directly
+ * load the PMD into MD_TWC.  The 8M pages are only used for kernel

+ * responsibility of the code setting the sigcontext to set this pointer to
+ * either NULL (if this processor does not support the VMX feature) or the
+ * address of the first quadword within the allocated (vmx_reserve) area.
+ *
+ * The pointer (v_regs) of vector type (elf_vrreg_t) is type compatible with
+ * an array of 34 quadword entries (elf_vrregset_t).  The entries with
+ * indexes 0-31 contain the corresponding vector registers.  The entry with
+ * index 32 contains the vscr as the last word (offset 12) within the
+ * quadword.  This allows the vscr to be stored as either a quadword (since
+ * it must be copied via a vector register to/from storage) or as a word.
+ * The entry with index 33 contains the vrsave as the first word (offset 0)
+ * within the quadword.
+ *
+ * Part of the VSX data is stored here also by extending vmx_restore
+ * by an additional 32 double words.  Architecturally the layout of
+ * the VSR registers and how they overlap on top of the legacy FPR and

+  * i2c commands

+  * To issue an i2c command, first is to send a parameter block to the

+  * eventually followed by data for a write:
+  *
+  * 0: bus number (from device-tree usually, SMU has lots of busses !)
+  * 1: transfer type/format (see below)
+  * 2: device address. For combined and combined4 type transfers, this
+  *    is the "write" version of the address (bit 0x01 cleared)
+  * 3: subaddress length (0..3)
+  * 4: subaddress byte 0 (or only byte for subaddress length 1)
+  * 5: subaddress byte 1
+  * 6: subaddress byte 2
+  * 7: combined address (device address for combined mode data phase)
+  * 8: data length
+  *
+  * The transfer types are the same good old Apple ones it seems,
+  * that is:
+  *   - 0x00: Simple transfer
+  *   - 0x01: Subaddress transfer (addr write + data tx, no restart)
+  *   - 0x02: Combined transfer (addr write + restart + data tx)
+  *
+  * This is then followed by actual data for a write.
+  *
+  * At this point, the OF driver seems to have a limitation on transfer
+  * sizes of 0xd bytes on reads and 0x5 bytes on writes. I do not know
+  * wether this is just an OF limit due to some temporary buffer size
+  * or if this is an SMU imposed limit. This driver has the same limitation
+  * for now as I use a 0x10 bytes temporary buffer as well
+  *
+  * Once that is completed, a response is expected from the SMU. This is
+  * obtained via a command of type 0x9a with a length of 1 byte containing
+  * 0 as the data byte. OF also fills the rest of the data buffer with 0xff's
+  * though I can't tell yet if this is actually necessary. Once this command
+  * is complete, at this point, all I can tell is what OF does. OF tests
+  * byte 0 of the reply:
+  *   - on read, 0xfe or 0xfc : bus is busy, wait (see below) or nak ?
+  *   - on read, 0x00 or 0x01 : reply is in buffer (after the byte 0)
+  *   - on write, < 0 -> failure (immediate exit)
+  *   - else, OF just exists (without error, weird)
+  *
+  * So on read, there is this wait-for-busy thing when getting a 0xfc or
+  * 0xfe result. OF does a loop of up to 64 retries, waiting 20ms and
+  * doing the above again until either the retries expire or the result
+  * is no longer 0xfe or 0xfc
+  *
+  * The Darwin I2C driver is less subtle though. On any non-success status
+  * from the response command, it waits 5ms and tries again up to 20 times,
+  * it doesn't differenciate between fatal errors or "busy" status.
+  *
+  * This driver provides an asynchronous paramblock based i2c command
+  * interface to be used either directly by low level code or by a higher
+  * level driver interfacing to the linux i2c layer. The current
+  * implementation of this relies on working timers & timer interrupts
+  * though, so be careful of calling context for now. This may be "fixed"
+  * in the future by adding a polling facility.

+ * either in the last 16 bits of property "smu-version-pmu" or as the 16
+ * bytes at offset 1 of "smu-version-info"
+ *
+ * For each chunk, the command takes 7 bytes of arguments:
+ *  byte 0: subcommand code (0x02)
+ *  byte 1: 0x04 (always, I don't know what it means, maybe the address
+ *                space to use or some other nicety. It's hard coded in OF)
+ *  byte 2..5: SMU address of the chunk (big endian 32 bits)

+ * Memory barrier.
+ * The sync instruction guarantees that all memory accesses initiated
+ * by this processor have been performed (with respect to all other
+ * mechanisms that access memory).  The eieio instruction is a barrier
+ * providing an ordering (separately) for (a) cacheable stores and (b)
+ * loads and stores to non-cacheable memory (e.g. I/O devices).
+ *
+ * mb() prevents loads and stores being reordered across this point.
+ * rmb() prevents loads being reordered across this point.
+ * wmb() prevents stores being reordered across this point.
+ * read_barrier_depends() prevents data-dependent loads being reordered
+ *	across this point (nop on PPC).
+ *
+ * We have to use the sync instructions for mb(), since lwsync doesn't
+ * order loads with respect to previous stores.  Lwsync is fine for
+ * rmb(), though. Note that rmb() actually uses a sync on 32-bit
+ * architectures.
+ *
+ * For wmb(), we use sync since wmb is used in drivers to order
+ * stores to system memory with respect to writes to the device.
+ * However, smp_wmb() can be a lighter-weight lwsync or eieio barrier
+ * on SMP since it is only used to order updates to system memory.

+ * Obviously, the GART is not cache coherent and so any change to it
+ * must be flushed to memory (or maybe just make the GART space non
+ * cachable). AGP memory itself doens't seem to be cache coherent neither.
+ *
+ * In order to invalidate the GART (which is probably necessary to inval
+ * the bridge internal TLBs), the following sequence has to be written,
+ * in order, to the GART_CTRL register:
+ *
+ *   UNI_N_CFG_GART_ENABLE | UNI_N_CFG_GART_INVAL
+ *   UNI_N_CFG_GART_ENABLE
+ *   UNI_N_CFG_GART_ENABLE | UNI_N_CFG_GART_2xRESET
+ *   UNI_N_CFG_GART_ENABLE
+ *
+ * As far as AGP "features" are concerned, it looks like fast write may
+ * not be supported but this has to be confirmed.
+ *
+ * Turning on AGP seem to require a double invalidate operation, one before
+ * setting the AGP command register, on after.
+ *
+ * Turning off AGP seems to require the following sequence: first wait
+ * for the AGP to be idle by reading the internal status register, then
+ * write in that order to the GART_CTRL register:
+ *
+ *   UNI_N_CFG_GART_ENABLE | UNI_N_CFG_GART_INVAL
+ *   0
+ *   UNI_N_CFG_GART_2xRESET
+ *   0

+ *	copy of the task_struct, which is currently not used by gdb,
+ *	but it may come in handy at some point.  All of the registers
+ *	are stored as part of the upage.  The upage should always be
+ *	only one page long.
+ *  data: The data segment follows next.  We use current->end_text to
+ *	current->brk to pick up all of the user variables, plus any memory
+ *	that may have been sbrk'ed.  No attempt is made to determine if a
+ *	page is demand-zero or if a page is totally unused, we just cover
+ *	the entire range.  All of the addresses are rounded in such a way
+ *	that an integral number of pages is written.
+ *  stack: We need the stack information in order to get a meaningful
+ *	backtrace.  We need to write the data from usp to
+ *	current->start_stack, so we round each of these in order to be able
+ *	to write an integer number of pages.

+ * on the S flag.
+ *
+ * The value of ACTIVE_BIAS supports up to 65535 active processes.
+ *
+ * This should be totally fair - if anything is waiting, a process that wants a
+ * lock will go to the back of the queue. When the currently active lock is
+ * released, if there's a writer at the front of the queue, then that and only
+ * that will be woken up; if there's a bunch of consequtive readers at the

+/* Core file format: The core file is written in such a way that gdb
+   can understand it and provide useful information to the user (under
+   linux we use the 'trad-core' bfd).  There are quite a number of
+   obstacles to being able to view the contents of the floating point
+   registers, and until these are solved you will not be able to view the
+   contents of them.  Actually, you can read in the core file and look at
+   the contents of the user struct to find out what the floating point
+   registers contain.
+   The actual file contents are as follows:
+   UPAGE: 1 page consisting of a user struct that tells gdb what is present
+   in the file.  Directly after this is a copy of the task_struct, which
+   is currently not used by gdb, but it may come in useful at some point.
+   All of the registers are stored as part of the upage.  The upage should
+   always be only one page.
+   DATA: The data area is stored.  We use current->end_text to
+   current->brk to pick up all of the user variables, plus any memory
+   that may have been malloced.  No attempt is made to determine if a page
+   is demand-zero or if a page is totally unused, we just cover the entire
+   range.  All of the addresses are rounded in such a way that an integral
+   number of pages is written.
+   STACK: We need the stack information in order to get a meaningful
+   backtrace.  We need to write the data from (esp) to
+   current->start_stack, so we round each of these off in order to be able
+   to write an integer number of pages.
+   The minimum core file size is 3 pages, or 12288 bytes.

+ * Hardware and software bit definitions for the PTEL value (see below for

+ *
+ * - Bits 0 and 7 are reserved on SH-3 (_PAGE_WT and _PAGE_SZ1 on SH-4).
+ *
+ * - Bit 1 is the SH-bit, but is unused on SH-3 due to an MMU bug (the
+ *   hardware PTEL value can't have the SH-bit set when MMUCR.IX is set,
+ *   which is the default in cpu-sh3/mmu_context.h:MMU_CONTROL_INIT).
+ *
+ *   In order to keep this relatively clean, do not use these for defining
+ *   SH-3 specific flags until all of the other unused bits have been
+ *   exhausted.
+ *
+ * - Bit 9 is reserved by everyone and used by _PAGE_PROTNONE.
+ *
+ * - Bits 10 and 11 are low bits of the PPN that are reserved on >= 4K pages.
+ *   Bit 10 is used for _PAGE_ACCESSED, bit 11 remains unused.
+ *
+ * - On 29 bit platforms, bits 31 to 29 are used for the space attributes
+ *   and timing control which (together with bit 0) are moved into the
+ *   old-style PTEA on the parts that support it.

+ *
+ * SH-X2 MMUs and extended PTEs
+ *
+ * SH-X2 supports an extended mode TLB with split data arrays due to the
+ * number of bits needed for PR and SZ (now EPR and ESZ) encodings. The PR and
+ * SZ bit placeholders still exist in data array 1, but are implemented as
+ * reserved bits, with the real logic existing in data array 2.
+ *
+ * The downside to this is that we can no longer fit everything in to a 32-bit
+ * PTE encoding, so a 64-bit pte_t is necessary for these parts. On the plus
+ * side, this gives us quite a few spare bits to play with for future usage.

+ *  data: The data segment follows next.  We use current->end_text to
+ *	current->brk to pick up all of the user variables, plus any memory
+ *	that may have been sbrk'ed.  No attempt is made to determine if a
+ *	page is demand-zero or if a page is totally unused, we just cover
+ *	the entire range.  All of the addresses are rounded in such a way
+ *	that an integral number of pages is written.
+ *  stack: We need the stack information in order to get a meaningful

+ * This is an alias, but it works because it is an uncached mapping.
+ * Second mapping is for device visible address, or "bus" address.
+ * The bus address is returned at '*pba'.
+ *
+ * These functions seem distinct, but are hard to split. On sun4c,
+ * at least for now, 'a' is equal to bus address, and retured in *pba.
+ * On sun4m, page attributes depend on the CPU type, so we have to
+ * know if we are mapping RAM or I/O, so it has to be an additional argument
+ * to a separate mapping function for CPU visible mappings.

+/* Sun4v hypervisor interfaces and defines.
+ *
+ * Hypervisor calls are made via traps to software traps number 0x80
+ * and above.  Registers %o0 to %o5 serve as argument, status, and
+ * return value registers.
+ *
+ * There are two kinds of these traps.  First there are the normal
+ * "fast traps" which use software trap 0x80 and encode the function
+ * to invoke by number in register %o5.  Argument and return value
+ * handling is as follows:
+ *
+ * -----------------------------------------------
+ * |  %o5  | function number |     undefined     |
+ * |  %o0  |   argument 0    |   return status   |
+ * |  %o1  |   argument 1    |   return value 1  |
+ * |  %o2  |   argument 2    |   return value 2  |
+ * |  %o3  |   argument 3    |   return value 3  |
+ * |  %o4  |   argument 4    |   return value 4  |
+ * -----------------------------------------------
+ *
+ * The second type are "hyper-fast traps" which encode the function
+ * number in the software trap number itself.  So these use trap
+ * numbers > 0x80.  The register usage for hyper-fast traps is as
+ * follows:
+ *
+ * -----------------------------------------------
+ * |  %o0  |   argument 0    |   return status   |
+ * |  %o1  |   argument 1    |   return value 1  |
+ * |  %o2  |   argument 2    |   return value 2  |
+ * |  %o3  |   argument 3    |   return value 3  |
+ * |  %o4  |   argument 4    |   return value 4  |
+ * -----------------------------------------------
+ *
+ * Registers providing explicit arguments to the hypervisor calls
+ * are volatile across the call.  Upon return their values are
+ * undefined unless explicitly specified as containing a particular
+ * return value by the specific call.  The return status is always
+ * returned in register %o0, zero indicates a successful execution of
+ * the hypervisor call and other values indicate an error status as
+ * defined below.  So, for example, if a hyper-fast trap takes
+ * arguments 0, 1, and 2, then %o0, %o1, and %o2 are volatile across
+ * the call and %o3, %o4, and %o5 would be preserved.
+ *
+ * If the hypervisor trap is invalid, or the fast trap function number
+ * is invalid, HV_EBADTRAP will be returned in %o0.  Also, all 64-bits
+ * of the argument and return values are significant.

+ *
+ * A guest uses this API to set a watchdog timer.  Once the gues has set
+ * the timer, it must call the timer service again either to disable or
+ * postpone the expiration.  If the timer expires before being reset or
+ * disabled, then the hypervisor take a platform specific action leading
+ * to guest termination within a bounded time period.  The platform action
+ * may include recovery actions such as reporting the expiration to a
+ * Service Processor, and/or automatically restarting the gues.
+ *
+ * The 'timeout' parameter is specified in milliseconds, however the
+ * implementated granularity is given by the 'watchdog-resolution'
+ * property in the 'platform' node of the guest's machine description.
+ * The largest allowed timeout value is specified by the
+ * 'watchdog-max-timeout' property of the 'platform' node.
+ *
+ * If the 'timeout' argument is not zero, the watchdog timer is set to
+ * expire after a minimum of 'timeout' milliseconds.
+ *
+ * If the 'timeout' argument is zero, the watchdog timer is disabled.
+ *
+ * If the 'timeout' value exceeds the value of the 'max-watchdog-timeout'
+ * property, the hypervisor leaves the watchdog timer state unchanged,
+ * and returns a status of EINVAL.
+ *
+ * The 'time remaining' return value is valid regardless of whether the
+ * return status is EOK or EINVAL.  A non-zero return value indicates the
+ * number of milliseconds that were remaining until the timer was to expire.
+ * If less than one millisecond remains, the return value is '1'.  If the
+ * watchdog timer was disabled at the time of the call, the return value is
+ * zero.
+ *
+ * If the hypervisor cannot support the exact timeout value requested, but
+ * can support a larger timeout value, the hypervisor may round the actual
+ * timeout to a value larger than the requested timeout, consequently the
+ * 'time remaining' return value may be larger than the previously requested
+ * timeout value.
+ *
+ * Any guest OS debugger should be aware that the watchdog service may be in
+ * use.  Consequently, it is recommended that the watchdog service is
+ * disabled upon debugger entry (e.g. reaching a breakpoint), and then
+ * re-enabled upon returning to normal execution.  The API has been designed
+ * with this in mind, and the 'time remaining' result of the disable call may

+ *	tsbnum		TSB number.  Indentifies which io-tsb is used.
+ *			For this version of the specification, tsbnum
+ *			must be zero.
+ *
+ *	tsbindex	TSB index.  Identifies which entry in the TSB
+ *			is used.  The first entry is zero.
+ *
+ *	tsbid		A 64-bit aligned data structure which contains
+ *			a tsbnum and a tsbindex.  Bits 63:32 contain the
+ *			tsbnum and bits 31:00 contain the tsbindex.
+ *
+ *			Use the HV_PCI_TSBID() macro to construct such
+ * 			values.
+ *
+ *	io_attributes	IO attributes for IOMMU mappings.  One of more
+ *			of the attritbute bits are stores in a 64-bit
+ *			value.  The values are defined below.
+ *
+ *	r_addr		64-bit real address
+ *
+ *	pci_device	PCI device address.  A PCI device address identifies
+ *			a specific device on a specific PCI bus segment.
+ *			A PCI device address ia a 32-bit unsigned integer
+ *			with the following format:
+ *
+ *				00000000.bbbbbbbb.dddddfff.00000000
+ *
+ *			Use the HV_PCI_DEVICE_BUILD() macro to construct
+ *			such values.
+ *
+ *	pci_config_offset
+ *			PCI configureation space offset.  For conventional
+ *			PCI a value between 0 and 255.  For extended
+ *			configuration space, a value between 0 and 4095.
+ *
+ *			Note: For PCI configuration space accesses, the offset
+ *			      must be aligned to the access size.
+ *
+ *	error_flag	A return value which specifies if the action succeeded
+ *			or failed.  0 means no error, non-0 means some error
+ *			occurred while performing the service.
+ *
+ *	io_sync_direction
+ *			Direction definition for pci_dma_sync(), defined
+ *			below in HV_PCI_SYNC_*.
+ *
+ *	io_page_list	A list of io_page_addresses, an io_page_address is
+ *			a real address.
+ *
+ *	io_page_list_p	A pointer to an io_page_list.
+ *
+ *	"size based byte swap" - Some functions do size based byte swapping
+ *				 which allows sw to access pointers and
+ *				 counters in native form when the processor
+ *				 operates in a different endianness than the
+ *				 IO bus.  Size-based byte swapping converts a

+ * comparison TAG based upon the virtual address and context which

+ * 	retry
+ *

+ * Each 16-byte slot of the TSB is the 8-byte tag and then the 8-byte

+ * field.
+ *
+ * Like the powerpc hashtables we need to use locking in order to
+ * synchronize while we update the entries.  PTE updates need locking
+ * as well.
+ *
+ * We need to carefully choose a lock bits for the TSB entry.  We

+ *
+ * -----------------------------------------------------------
+ * |impl-vers| RSV |TC|AC|SP|BM|PC|MBM|SB|IC|DC|PSO|RSV|NF|ME|
+ * -----------------------------------------------------------
+ *  31     24 23-17 16 15 14 13 12 11  10  9  8  7  6-2  1  0
+ *
+ * TC: Tablewalk Cacheable -- 0 = Twalks are not cacheable in E-cache
+ *                            1 = Twalks are cacheable in E-cache
+ *
+ * GNU/Viking will only cache tablewalks in the E-cache (mxcc) if present
+ * and never caches them internally (or so states the docs).  Therefore
+ * for machines lacking an E-cache (ie. in MBUS mode) this bit must
+ * remain cleared.
+ *
+ * AC: Alternate Cacheable -- 0 = Passthru physical accesses not cacheable
+ *                            1 = Passthru physical accesses cacheable
+ *
+ * This indicates whether accesses are cacheable when no cachable bit
+ * is present in the pte when the processor is in boot-mode or the
+ * access does not need pte's for translation (ie. pass-thru ASI's).
+ * "Cachable" is only referring to E-cache (if present) and not the
+ * on chip split I/D caches of the GNU/Viking.
+ *
+ * SP: SnooP Enable -- 0 = bus snooping off, 1 = bus snooping on
+ *
+ * This enables snooping on the GNU/Viking bus.  This must be on
+ * for the hardware cache consistency mechanisms of the GNU/Viking
+ * to work at all.  On non-mxcc GNU/Viking modules the split I/D
+ * caches will snoop regardless of whether they are enabled, this
+ * takes care of the case where the I or D or both caches are turned
+ * off yet still contain valid data.  Note also that this bit does
+ * not affect GNU/Viking store-buffer snoops, those happen if the
+ * store-buffer is enabled no matter what.
+ *
+ * BM: Boot Mode -- 0 = not in boot mode, 1 = in boot mode
+ *
+ * This indicates whether the GNU/Viking is in boot-mode or not,
+ * if it is then all instruction fetch physical addresses are
+ * computed as 0xff0000000 + low 28 bits of requested address.
+ * GNU/Viking boot-mode does not affect data accesses.  Also,
+ * in boot mode instruction accesses bypass the split on chip I/D
+ * caches, they may be cached by the GNU/MXCC if present and enabled.
+ *
+ * MBM: MBus Mode -- 0 = not in MBus mode, 1 = in MBus mode
+ *
+ * This indicated the GNU/Viking configuration present.  If in
+ * MBUS mode, the GNU/Viking lacks a GNU/MXCC E-cache.  If it is
+ * not then the GNU/Viking is on a module VBUS connected directly
+ * to a GNU/MXCC cache controller.  The GNU/MXCC can be thus connected
+ * to either an GNU/MBUS (sun4m) or the packet-switched GNU/XBus (sun4d).
+ *
+ * SB: StoreBuffer enable -- 0 = store buffer off, 1 = store buffer on
+ *
+ * The GNU/Viking store buffer allows the chip to continue execution
+ * after a store even if the data cannot be placed in one of the
+ * caches during that cycle.  If disabled, all stores operations
+ * occur synchronously.
+ *
+ * IC: Instruction Cache -- 0 = off, 1 = on
+ * DC: Data Cache -- 0 = off, 1 = 0n
+ *
+ * These bits enable the on-cpu GNU/Viking split I/D caches.  Note,
+ * as mentioned above, these caches will snoop the bus in GNU/MBUS
+ * configurations even when disabled to avoid data corruption.
+ *
+ * NF: No Fault -- 0 = faults generate traps, 1 = faults don't trap
+ * ME: MMU enable -- 0 = mmu not translating, 1 = mmu translating
+ *
