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).
might be able to do Precise in hardware, so leave it up to the driver.
- Add a helper function for computing a set of offsets for smooth trapezoid
rasterizing using many sharp trapezoids.
RasterizeTrapezoid screen function. These hooks will be called for
imprecise, non-sharp trapezoids with A8 destinations.
Note that the current main consumer of trapezoids, cairo, is requesting
precise, sharp trapezoids by not changing the default Picture
attributes, but gets non-sharp effects in software because fb bases its
choice of sharp/non-sharp on the mask format being A8 vs A1, and cairo
asks for A8. Follow fb's (poor?) example by ignoring the sharp setting
and basing the choice off of the mask being A8.
heuristic, delay the decision until the first
kaaPixmapUse{Screen|Memory}, and put it in framebuffer if UseScreen was
called. Provides a significant improvement in cairo speeds (100%
speedup in cairogears here) and is likely to improve text performance
as well.
