in the kaa structure: markSync and waitMarker. The first, if set,
returns a hardware-dependent marker number which can then be waited for
with waitMarker. If markSync is absent (which is the case on all
drivers currently), waitMarker must wait for idle on any given marker
number. The intention is to allow for more parallelism when we get
downloading from framebuffer, or more fine-grained idling.
- Replace the KdMarkSync/KdCheckSync functions with kaaMarkSync and
kaaWaitSync. These will need to be refined when KAA starts being smart
about using them. Merge kpict.c into kasync.c since kasyn.c has all the
rest of these fallback funcs.
- Restructure all drivers to initialize a KaaInfo structure by hand rather
than statically in dubious order.
- Whack the i810 driver into shape in hopes that it'll work after this
change (it certainly wouldn't have before this). Doesn't support my
i845 though.
- Make a new KXV helper to avoid duplicated code to fill the region with
the necessary color key. Use it in i810 and mach64 (tested).
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.
offscreen pixmap area, and set it when any rendering occurs. When
moving a pixmap out of offscreen, don't read data back if it wasn't
dirtied (compared to the system memory copy).
- Add libdrm and libdri. Portions of the DRI extension are stubbed out.
- Use the DRM in the ATI driver when available. This provides a minor
performance improvement in x11perf, and opens the possibility of using
the 3d hardware for acceleration in the future.
- Implement solid fill acceleration for Composite in KAA.
- Implement Blend hook for Composite and use it on r128.
- Fix a bug of mine that resulted in overuse of offscreen memory.
- Fix many miscellaneous bugs in ATI driver and add PCI IDs.
