* [SCSI] sgiwd93: Fix compilation warningDmitri Vorobiev2009-01-021-1/+2
| | | | | | | | | | | | | | | | | The remove() callback in platform drivers should return int in accordance to the definition of the platform_driver structure. However, the SGI-specific WD93 SCSI controller driver defines the callback as a void function, which causes the following compilation warning: drivers/scsi/sgiwd93.c:314: warning: initialization from incompatible pointer type This patch fixes the warning by changing the return type of the remove() callback to what the core driver code requires.

* [SCSI] WD33C93: let platform stub override no_sync/fast/dma_modeThomas Bogendoerfer2008-04-071-3/+4
| | | | | | | | | | | SGI machines with WD33C93 allow usage of burst mode DMA, which increases performance noticable. To make this selectable by the sgiwd93 stub, setting the values for no_sync, fast and dma_mode has been moved to the individual platform stubs.

* [SCSI] sgiwd93: use cached memory access to make driver work on IP28Thomas Bogendoerfer2008-01-301-25/+39
| | | | | | | | | SGI IP28 machines would need special treatment (enable adding addtional wait states) when accessing memory uncached. To avoid this pain I changed the driver to use only cached access to memory.

* [SCSI] sgiwd93: interfacing to wd33c93peter fuerst2007-02-161-2/+3
| | | | | | | | | | | | | | | | | | | | | 1) sgiwd93 used to switch off asynchronous mode on the wd33c93, discarding any "nosync"-requests from the commandline. But we need to allow "nosync"-requests for selected devices, for example the Pioneer DVD305S. (For the curious: this device accepts the SDTR from wd33c93 and success- fully sends inquiry data in sync mode, but after the data phase in the inquiry command does an unexpected disconnect, seemingly sending no "status" or "command complete". Forcing async transfers makes it work together flawlessly with the wd33c93. Of course, preferable would be, to implement wd33c93's "resume command" stuff, but that probably will not come soon.) 2) Maximize benefit from the preceding Fast SCSI patch for wd33c93 by passing the higher input-clock frequency explicitely. To be applied after the mentioned wd33c93 patch. Signed-off-by: peter fuerst <post@pfrst.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
