2007-03-20	radeon: Only sync to hardware when really necessary with EXA.	Michel Dänzer
	In particular, don't sync again after accelerated DownloadFromScreen, which syncs implicitly. This avoids calling into the kernel when it's not necessary, which can be relevant in some situations.
2006-12-19	radeon: Advertise 2D engine limits to EXA when we're not using the 3D engine.	Michel Dänzer
	Also round up to the maximum width and height, as that's what EXA compares.
2006-09-30	radeon: Add support for page flipping with EXA.	Michel Dänzer
	Also use the damage layer directly instead of via shadowfb and blit dirty rectangles to the second page in LeaveServer in order to try and improve the tradeoff between performance and correctness.
2006-07-03	Do even less cache flushing when the previous engine mode is known.	Michel Dänzer
	OTOH, flush everything when the previous engine mode is unknown, and mark the engine mode as unknown in a couple more cases.
2006-06-24	Bug #7274: Fix corruption with 'small' accelerated DownloadFromScreen transfers.	Michel Dänzer

2006-06-18	Implement accelerated EXA DownloadFromScreen hook.	Michel Dänzer
	x11perf -getimage numbers only increase by about 20-30% on my PowerBook with an M9, but by about 100 times(!) with a PCIe X550. I suspect the former could perform better with PCI as opposed to AGP transfers, which would also remove the need to disable this by default with AGP.
2006-06-18	Remove #include <fbdevhw.h>, not used here.	Michel Dänzer

2006-05-01	Bugzilla #6755 <https://bugs.freedesktop.org/show_bug.cgi?id=6755> Patch	Michel Daenzer
	#5536 <https://bugs.freedesktop.org/attachment.cgi?id=5536>: Change HostDataBlit interface to take dst_offset_pitch and coordinates instead of just a destination pointer, as the latter is not sufficient with tiling. Also, use HW clipping to avoid overwriting destination data outside of the specified width. Adapt to new HostDataBlit interface. This fixes corruption with UploadToScreen to the front buffer (from exaPutImage).
2006-03-22	Convert use of xf86fopen() and other xf86 wrapped libc symbols to use libc	Kristian Høgsberg
	symbols directly. The xf86* versions aren't supposed to be used directly. Drop libc wrapper; don't include xf86_ansic.h and add includes now missing.
2006-03-09	Update drivers that support EXA for the new EXA ABI. This consists of	Eric Anholt
	moving all the accel and card members into the driver ptr, filling in the exa_major/ exa_minor fields, and always using LoadSubModule so we can check the module version up front. Only tested on ATI.
2005-09-18	Break EXA ABI while we still can. Add coordinates to the UploadToScreen	Eric Anholt
	hook so we can upload a subset of a pixmap, and convert the current drivers to respect that. Use this support to directly UploadToScreen in exaGlyphs, providing a 47.4% +/-2.4% decrease in wall time for ls -lR programs/Xserver in an antialiased gnome-terminal on an M6 (n=3, caches hot). I would have bumped major version, only I can't tell what the EXA_VERSION_* is supposed to be doing as opposed to the module version.
2005-09-12	Fix Radeon EXA for when RENDER isn't defined	Dave Airlie

2005-09-11	Add support for EXA to the radeon driver. Building EXA and XAA support is	Eric Anholt
	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.
