x86, geode-mfgpt: check IRQ before using MFGPT as clocksource

2008-08-15T15:12:32+00:00

Adds a simple IRQ autodetection to the AMD Geode MFGPT driver, and more
importantly, adds some checks, if IRQs can actually be received on the
chosen line.  This fixes cases where MFGPT is selected as clocksource
though not producing any ticks, so the kernel simply starves during
boot.

x86: consolidate header guards

2008-07-22T19:31:34+00:00

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.

x86, geode: add a VSA2 ID for General Software

2008-06-19T12:19:03+00:00

General Software writes their own VSA2 module for their version
of the Geode BIOS, which returns a different ID then the standard
VSA2.  This was causing the framebuffer driver to break for most
GSW boards.

x86: geode: define geode_has_vsa2() even if CONFIG_MGEODE_LX is not set

2008-05-08T13:43:50+00:00

We want drivers to be able to use geode_has_vsa2 without having to worry
about what model geode is being compiled for.  This patch ensures that
geode_has_vsa2 is always defined.

x86: GEODE: cache results from geode_has_vsa2() and uninline

2008-05-08T13:43:50+00:00

This moves geode_has_vsa2 into a .c file, caches the result we get from
the VSA virtual registers, and causes the function to no longer be inline.

gxfb/lxfb: detect framebuffer size using an MSR if VSA2 isn't available

2008-04-28T15:58:40+00:00

If there's no VSA2 (ie, if we're using tinybios or OpenFirmware), use the
GLIU's P2D Range Offset Descriptor to determine how much memory we have
available for the framebuffer.

Originally based on a patch by Jordan Crouse.  Tested with OpenFirmware;
Pascal informs me that tinybios has a stub that fills in P2D_RO0.

x86: GEODE: add Virtual Systems Architecture detection

2008-04-28T15:58:35+00:00

This is generic VSA2 detection.  It's used by OLPC to determine whether or not
the BIOS contains VSA2, but since other BIOSes are coming out that don't use
the VSA (ie, tinybios), it might end up being useful for others.
