Include "compiler.h" to define __inline__ on non-gcc compilers

allow for PCI/AGP/PCIE cards. Set PCI gart allocation to only happen on
PCIE cards. Add Radeon PCIE card detection using capability bits.

controlled at compile time, plus the runtime option of Option
"AccelMethod" "EXA" or "XAA". The XAA support appears to remain as
before, while the EXA pieces need just a little more polishing. Notable
features:
- Render acceleration working on Radeon 100 and 200-series with DRI on.
- DRI works with EXA Notable issues:
- DGA disabled in the EXA case.
- Backbuffer moves disabled in the EXA case.
- No textured XVideo.
- MMIO render acceleration is close but still has some issues.
- Memory pressure while using Composite is really troublesome with DRI on.
This patch is based on an initial patch by Zack Rusin, with significant
work by Benjamin Herrenschmidt and myself.

- adjust limits for tiled surfaces on r3/4xx

change "foo.h" to <X11/foo.h> for core headers, e.g. X.h, Xpoll.h;
change "foo.h", "extensions/foo.h" and "X11/foo.h" to
<X11/extensions/foo.h> for extension headers, e.g. Xv.h;
change "foo.[ch]" to <X11/Xtrans/foo.[ch]> for Xtrans files.

caused by the tiling support (bug #2481)

Convert all XAA accel code to use explicit dst and src offset pitch
control to make it work. Use the new drm surface ioctls to set up the
tiled surfaces (if dri is enabled).

should now work on ppcs without usefbdev. To use this on ppc make sure
you set "usefbdev" to false. (bug 2089)
- Apply Benjamin Herrenschmidt's radeon patches (bug 2064)

- fix display detection (Hui Yu) bug 1559
- Add new option "BIOSHotkeys" to allow the bios to control output
switching (off by default) bug 2000
- update the savage man page to document the "CrtOnly" option

system memory to video RAM, which should reduce CPU usage especially
with larger videos. Can be disabled via Option "DMAForXv" if there
should be any stability issues, but it's been stable for me during a
week of testing. Based on a patch by Nikolaus Meine
<meine@tnt.uni-hannover.de>. Probably fix endianness issues in some
newer XVideo code, untested.
Also use hostdata blits to transfer RENDER image data to video RAM to avoid
idling the accelerator engine. Increases RENDER performance
significantly for me.
These changes were only tested on an M9 in a Titanium PowerBook but should
work with all Radeons where direct rendering is supported.

Render acceleration merges.
|
|
- Add Render acceleration for Radeon 100 and 200-series cards, enabled by
default. Notable performance gains include 27fps in cairogears instead
of 6fps (compared to 50 with glitz), and my disks are now the
bottleneck in an ls -lR in gnome-terminal. Only supported in DRI mode
because the MMIO submission hangs the card so far, but the code is left
in because it may be supportable soon.
- Add xorg.conf options to disable Render acceleration and to force the
subpixel order in the server (Hui Yu).
Many thanks to Hui Yu at ATI for the code this was based off of, Michel
Daenzer for bugfixes and suggestions, and LinuxFund for sponsoring the
work.

with the following notes:
- Savage and Mach64 (= ati/ati*.[ch] changes) DRI not merged due to
insecurity.
- VIA driver converted to new drmContext and drmHandle names.
- Radeon driver merge conflicted in many places, and MergedFB at least
could probably use some checking at this point.
