[PATCH] x86: Add acpi_user_timer_override option for Asus boards

2006-11-14T15:57:46+00:00

Timer overrides are normally disabled on Nvidia board because
they are commonly wrong, except on new ones with HPET support.
Unfortunately there are quite some Asus boards around that
don't have HPET, but need a timer override.

We don't know yet how to handle this transparently,
but at least add a command line option to force the timer override
and let them boot.

i386: clean up io-apic accesses

2006-11-01T17:11:00+00:00

This is preparation for fixing the ordering of the accesses that
got broken by the commit cf4c6a2f27f5db810b69dcb1da7f194489e8ff88 when
factoring out the "common" io apic routing entry accesses.

Move the accessor function (that were only used by io_apic.c) out
of a header file, and use proper memory-mapped accesses rather than
making up our own "volatile" pointers.

ACPI: Processor native C-states using MWAIT

2006-10-14T04:35:39+00:00

Intel processors starting with the Core Duo support
support processor native C-state using the MWAIT instruction.
Refer: Intel Architecture Software Developer's Manual
http://www.intel.com/design/Pentium4/manuals/253668.htm

Platform firmware exports the support for Native C-state to OS using
ACPI _PDC and _CST methods.
Refer: Intel Processor Vendor-Specific ACPI: Interface Specification
http://www.intel.com/technology/iapc/acpi/downloads/302223.htm

With Processor Native C-state, we use 'MWAIT' instruction on the processor
to enter different C-states (C1, C2, C3).  We won't use the special IO
ports to enter C-state and no SMM mode etc required to enter C-state.
Overall this will mean better C-state support.

One major advantage of using MWAIT for all C-states is, with this and
"treat interrupt as break event" feature of MWAIT, we can now get accurate
timing for the time spent in C1, C2, ..  states.

[VOYAGER] fix up ptregs removal mess

2006-10-13T03:25:03+00:00

Apparently whoever converted voyager never actually checked that the
patch would compile ...

Remove as much of the pt_regs references as possible and move the
remaining ones into line with what's in x86 generic.

[VOYAGER] fix up attribute packed specifiers in voyager.h

2006-10-13T03:23:18+00:00

The old style (attribute on each structure entry) never really worked.
Move it to an attribute per structure

[PATCH] Consolidate check_signature

2006-10-11T18:14:23+00:00

There's nothing arch-specific about check_signature(), so move it to
.  Use a cross between the Alpha and i386 implementations as
the generic one.

[PATCH] epoll_pwait()

2006-10-11T18:14:21+00:00

Implement the epoll_pwait system call, that extend the event wait mechanism
with the same logic ppoll and pselect do.  The definition of epoll_pwait
is:

int epoll_pwait(int epfd, struct epoll_event *events, int maxevents,
                 int timeout, const sigset_t *sigmask, size_t sigsetsize);

The difference between the vanilla epoll_wait and epoll_pwait is that the
latter allows the caller to specify a signal mask to be set while waiting
for events.  Hence epoll_pwait will wait until either one monitored event,
or an unmasked signal happen.  If sigmask is NULL, the epoll_pwait system
call will act exactly like epoll_wait.  For the POSIX definition of
pselect, information is available here:
