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).
