2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

2005-09-26[PATCH] yenta: don't mess with bridge control registerDaniel Ritz
In interrupt probing (both ISA and PCI) the bridge control register is used to change interrupt routing to ISA or PCI by changing bit 7. But this bit only controls the routing of card functional interrupts, not the CSC interrupts which are used for interrupt probing. A bad side effect of messing with this register in yenta_probe_irq() is that it can lead to irq storms if a card is inserted and already powered by the BIOS. Usage in yenta_sock_init() and yenta_config_init() seem to be fishy as well.

2005-09-07[PATCH] yenta: make ToPIC95 bridges work with 16bit cardsDaniel Ritz
ToPIC95 brides (and maybe some other too) require to use the ExCA registers to power up the socket if a 16bit card is pluged. allow socket drivers to set a flag so that yenta does just that. also clean up yenta_get_status() a bit to use the new yenta_get_power() function. Side note: ToPIC97 bridges (at least in Rev.5 i have) don't require this. Ryan Underwood <nemesis-lists@icequake.net> said: According to the mail that David Hinds received from a Toshiba engineer, ToPIC95 and 97 do require this, and ToPIC100 does not. Maybe you have a later revision. For all chips, 16-bit cards can be enabled through ExCA. So doesn't it make sense just to make this the default behavior for all Toshiba chips, to avoid corner cases showing up later? Daniel responded: I disagree with ryan to change anything for topic97 bridges. they work. and I couldn't find (read google) any report of a topic97 breaking on applying power with the CB registers. I'm having several toshba notebooks at work (and home) with topic95,97,100 bridges. Only the ones with a topic95 didn't work.

2005-08-04[PATCH] pci and yenta: pcibios_bus_to_resourceDominik Brodowski
In yenta_socket, we default to using the resource setting of the CardBus bridge. However, this is a PCI-bus-centric view of resources and thus needs to be converted to generic resources first. Therefore, add a call to pcibios_bus_to_resource() call in between. This function is a mere wrapper on x86 and friends, however on some others it already exists, is added in this patch (alpha, arm, ppc, ppc64) or still needs to be provided (parisc -- where is its pcibios_resource_to_bus() ?).

2005-08-02[PATCH] Obvious bugfix for yenta resource allocationPaul Mackerras
Recent changes (well, dating from 12 July) have broken cardbus on my powerbook: I get 3 messages saying "no resource of type xxx available, trying to continue", and if I plug in my wireless card, it complains that there are no resources allocated to the card. This all worked in 2.6.12. Looking at the code in yenta_socket.c, function yenta_allocate_res, it's obvious what is wrong: if we get to line 639 (i.e. there wasn't a usable preassigned resource), we will always flow through to line 668, which is the printk that I was seeing, even if a resource was successfully allocated. It looks to me as though there should be a return statement after the two config_writel's in each of the 3 branches of the if statements, so that the function returns after successfully setting up the resource. The patch below adds these return statements, and with this patch, cardbus works on my powerbook once again.

2005-06-23[PATCH] yenta TI: turn off interrupts during card power-on #2Daniel Ritz
- make boot-up card recognition more reliable (ie. redo interrogation always if there is no valid 'card inserted' state) (and yes, i saw it happening on an o2micro controller that both CB_CBARD and CB_16BITCARD bits were set at the same time) - also redo interrogation before probing the ISA interrupts. it's safer to do the probing with the socket in a clean state. - make card insert detect more reliable. yenta_get_status() now returns SS_PENDING as long as the card is not completley inserted and one of the voltage bits is set. also !CB_CBARD doesn't mean CB_16BITCARD. there is CB_NOTACARD as well, so make an explicit check for CB_16BITCARD. - for TI bridges: disable IRQs during power-on. in all-serial and tied interrupt mode the interrupts are always disabled for single-slot controllers. for two-slot contollers the disabling is only done when the other slot is empty. to force disabling there is a new module parameter now: pwr_irqs_off=Y (which is a regression for working setups. that's why it's an option, only use when required) - modparm to disable ISA interrupt probing (isa_probe, defaults to on) - remove unneeded code/cleanups (ie. merge yenta_events() into yenta_interrupts()) Signed-off-by: Daniel Ritz <daniel.ritz@gmx.ch> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
