alpha: more fixes for specific machine types

2007-04-17T23:36:27+00:00

arch/alpha/kernel/sys_sx164.c

	Earlier firmware revisions need MVI fix as well.

arch/alpha/kernel/sys_nautilus.c

	On UP1500 firmware reports wrong AGP IRQ (10 instead of 5).
	This causes interrupt storm if there is a PCI device that
	uses IRQ 5.

alpha: fixes for specific machine types

2007-04-17T23:36:27+00:00

Files:

arch/alpha/kernel/core_mcpcia.c
arch/alpha/kernel/sys_rawhide.c
include/asm-alpha/core_mcpcia.h

	Determine correct hose configuration; RAWHIDE family can have
        2 or 4 hoses, so make sure non-existent hoses are ignored.

arch/alpha/kernel/err_titan.c

	Supply a needed #include 

arch/alpha/kernel/module.c

	Add some useful output to the relocation overflow messages.

arch/alpha/kernel/sys_noritake.c

	Supply necessary noritake_end_irq() to correct interrupt handling.
	This fixes a problem first noted by hangs during boot probing with
	a DE500-BA TULIP NIC present.

arch/alpha/kernel/sys_sio.c

	Correct saving of original PIRQ register (PCI IRQ routing);
	change default PIRQ setting to leave PCI IRQs 9 and 14 free to
	be used for sound (Multia) and IDE (any), respectively.

include/asm-alpha/io.h

	Supply the "isa_virt_to_bus" routine.

[PATCH] disable init/initramfs.c: architectures

2007-02-11T18:51:25+00:00

Update all arch/*/kernel/vmlinux.lds.S to not include space for initramfs
when CONFIG_BLK_DEV_INITRAMFS is not selected.  This saves another 4 kbytes
on most platfoms (some reserve PAGE_SIZE for initramfs).

[PATCH] Set CONFIG_ZONE_DMA for arches with GENERIC_ISA_DMA

2007-02-11T18:51:19+00:00

As Andi pointed out: CONFIG_GENERIC_ISA_DMA only disables the ISA DMA
channel management.  Other functionality may still expect GFP_DMA to
provide memory below 16M.  So we need to make sure that CONFIG_ZONE_DMA is
set independent of CONFIG_GENERIC_ISA_DMA.  Undo the modifications to
mm/Kconfig where we made ZONE_DMA dependent on GENERIC_ISA_DMA and set
theses explicitly in each arches Kconfig.

Reviews must occur for each arch in order to determine if ZONE_DMA can be
switched off.  It can only be switched off if we know that all devices
supported by a platform are capable of performing DMA transfers to all of
memory (Some arches already support this: uml, avr32, sh sh64, parisc and
IA64/Altix).

In order to switch ZONE_DMA off conditionally, one would have to establish
a scheme by which one can assure that no drivers are enabled that are only
capable of doing I/O to a part of memory, or one needs to provide an
alternate means of performing an allocation from a specific range of memory
(like provided by alloc_pages_range()) and insure that all drivers use that
call.  In that case the arches alloc_dma_coherent() may need to be modified
to call alloc_pages_range() instead of relying on GFP_DMA.

PCI: make isa_bridge Alpha-only

Since isa_bridge is neither assigned any value !NULL nor used on !Alpha, 
there's no reason for providing it.

[PATCH] fdtable: Make fdarray and fdsets equal in size

2006-12-10T17:57:22+00:00

Currently, each fdtable supports three dynamically-sized arrays of data: the
fdarray and two fdsets.  The code allows the number of fds supported by the
fdarray (fdtable->max_fds) to differ from the number of fds supported by each
of the fdsets (fdtable->max_fdset).

In practice, it is wasteful for these two sizes to differ: whenever we hit a
limit on the smaller-capacity structure, we will reallocate the entire fdtable
and all the dynamic arrays within it, so any delta in the memory used by the
larger-capacity structure will never be touched at all.

Rather than hogging this excess, we shouldn't even allocate it in the first
place, and keep the capacities of the fdarray and the fdsets equal.  This
patch removes fdtable->max_fdset.  As an added bonus, most of the supporting
code becomes simpler.
