| * x86: consolidate header guardsVegard Nossum2008-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is the result of an automatic script that consolidates the format of all the headers in include/asm-x86/. The format: 1. No leading underscore. Names with leading underscores are reserved. 2. Pathname components are separated by two underscores. So we can distinguish between mm_types.h and mm/types.h. 3. Everything except letters and numbers are turned into single underscores. Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com>
* | x86, SGI UV: hardcode the TLB flush interrupt system vectorCliff Wickman2008-08-20
|/ | | | | | | | | | | | | The UV TLB shootdown mechanism needs a system interrupt vector. Its vector had been hardcoded as 200, but needs to moved to the reserved system vector range so that it does not collide with some device vector. This is still temporary until dynamic system IRQ allocation is provided. But it will be needed when real UV hardware becomes available and runs 2.6.27.

* x86 BIOS interface for RTC on SGI UVRuss Anderson2008-07-18
| | | | | | | | | | | | | | | Real-time code needs to know the number of cycles per second on SGI UV. The information is provided via a run time BIOS call. This patch provides the linux side of that interface. This is the first of several run time BIOS calls to be defined in uv/bios.h and bios_uv.c. Note that BIOS_CALL() is just a stub for now. The bios side is being worked on. Signed-off-by: Russ Anderson <rja@sgi.com> Cc: Jack Steiner <steiner@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86, SGI UV: TLB shootdown using broadcast assist unitCliff Wickman2008-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TLB shootdown for SGI UV. Depends on patch (in tip/x86/irq): x86-update-macros-used-by-uv-platform.patch Jack Steiner May 29 This patch provides the ability to flush TLB's in cpu's that are not on the local node. The hardware mechanism for distributing the flush messages is the UV's "broadcast assist unit". The hook to intercept TLB shootdown requests is a 2-line change to native_flush_tlb_others() (arch/x86/kernel/tlb_64.c). This code has been tested on a hardware simulator. The real hardware is not yet available. The shootdown statistics are provided through /proc/sgi_uv/ptc_statistics. The use of /sys was considered, but would have required the use of many /sys files. The debugfs was also considered, but these statistics should be available on an ongoing basis, not just for debugging. Issues to be fixed later: - The IRQ for the messaging interrupt is currently hardcoded as 200 (see UV_BAU_MESSAGE). It should be dynamically assigned in the future. - The use of appropriate udelay()'s is untested, as they are a problem in the simulator.
