reading a register/attempting DMA. Now it'll wait for a certain number
of seconds rather than a certain number of times through the loop
before deciding that it's timed out and resetting the hardware. Also,
add more timeout handling, and reset the draw state after resetting the
engine.
are always emitted. Fix the real problem, which was not enough regs
being initialized in ati_draw.c. Fix a typo that was resulting in alpha
coming out as 0 * src or 0 * broken instead of src * 1 or src * mask.
Assign the blending results to R0, as appears to be necessary. Unbreak
the dst-alpha-blend-with-no-dst-alpha code. Yow. And set the right DMA
count for the r200 traps code.
non-mask rendering. Reenable it. Also, R200TexFormats was used instead
of R100 in one place. Harmless so far, because the formats were in the
same order.
troubles.
- Move the RemoveBlockAndWakeupHandlers to match
RegisterBlockAndWakeupHandlers.
- Enable R100 trapezoid "acceleration" when DRI is working, so that it can
be exposed and worked on.
instead of ErrorFs for things that are really bad, and put limits on
some loops. Now, sometimes instead of hanging the entire system, we
(mostly-) cleanly drop to console when the card has hung.
not doing an add of 1 per triangle like I hoped, and instead seems to
be saturating all the pixels or something. The R100 acceleration
renders pretty well, with some gaps. Note that both are slower than
software due to lack of DMA to submit vertices.
- Mostly fix R128 and Radeon transform support, including supporting
bilinear filtering on R128. Subpixel offsets are still probably an
issue (reported by rendercheck), but I want to make 100% sure about my
understanding of the protocol before changing everybody, including fb.
- Add support for dst formats without alpha to R128 Composite.
- Remove the R128 Blend code, which has long outlived its usefulness. (I
kept it around for one reason: It could be useful for the w/h > 1024
case with no mask and a non-src op. That seems pretty infrequent and
not worth the trouble).
- On R128, don't refer to an old Composite's mask transform when the
current Composite doesn't have a mask.
- Staticize some global variables in r128_composite.c.
solid-fill-based composite acceleration.
- Use a real pixmap when doing an UploadToScratch (For pDrawable->type ==
DRAWABLE_WINDOW, you need to get the backing pixmap).
- Pass back the x/y offsets from kaaGetOffscreenPixmap unconditionally,
because they'll be used in the scratch case.
- Turn on the Render acceleration for Rage 128 and Radeon 100-series at
last!
- Add monochrome hardware cursor support.
- Try to auto-detect AGP support for DRI on Radeons. And fail. Detect it
properly on R128.
- Set up card for pseudo-DMA if possible. Convert 2D rendering code to
prepare DMA packets only. Use generic code to decode DMA packets to
MMIO if PDMA is unavailable. Add WIP code to support "real" DMA without
DRM support.
- Dispatch pending DMA commands when the server sleeps. Otherwise some
things, such as typing in an xterm, wouldn't show up for a time.
- Fix Radeon Composite acceleration in many ways, and add Rage 128
Composite acceleration. Disable them both due to still-not-understood
issues they have. They fail with In, Out, AtopReverse, and Xor, and
text rendering is strange.
- Add textured XV support for R100 and Rage 128. No brightness/sat
controls, but it does support multiple ports, and cooperates with
Composite.
- Add WIP code for hostdata uploads.
- Many cleanups and fixes.
- Reserve areas for back/depth/span when USING_DRI && GLXEXT. This would be
better in a TransitionTo3d, but we'd need to work with the offscreen
memory manager for that.
- Misc. fixes to ati_dri.c for DRI+GLX. Needs more work still.
pixmap into temporary offscreen storage. Subsequent UploadToScratch may
clobber the data of previous ones. This allows hardware acceleration of
composite operations on glyphs.
- Add a new UploadToScreen kaa hook for doing the actual moving of data to
framebuffer. This would allow us to do things like hostdata blits or
memcpy to agp and then blit.
- Add an UploadToScreen on ATI which is just memcpy, but which will be
replaced with a hostdata blit soon.
- Add UploadToScratch on ATI and reserve 64k of scratch space. This
provided a 3x speedup of rgb24text on my Radeon.
emitting as a tri fan rather than a tri list. A rect list would save an
additional vertex (out of 4) per rectangle, but there's no measurable
speed difference and the tri fan may be useful when transforms come
into play.
