DAVINCI: Hardware acceleration using the DSP with a special firmware and
kernel module.
The DSP runs an ~8k firmware (in L1 cache) and provides different
functions. These
are called by writing a command packet into the 512k command queue in
memory. Each
function can have up to seven 32 bit arguments, up to eight flags and a sub
function
index of 8 bit.
There's a low and high priority queue, but only one is implemented at the
moment. The
idea is that the high priority queue can preempt the low priority queue at
any time when
a command is added. The low priority queue can only continue when the high
priority queue
is empty.
There are no interrupts from DSP nor to it so far. Waiting for a free queue
entry or for
an empty queue uses usleep() at the moment, but it's working quite well. An
interrupt handler
and a few ioctls() should be added.
Text rendering is just white at the moment. Blended rectangle filling will
be implemented.
Graphics Layer updates from ARGB to RGB16/A3 (dithered) planes are done by
the DSP, very fast.
We're mainly working on MPEG2 at the moment...

DEBUG: Added checks if debug support is disabled.
If DIRECT_ENABLE_DEBUG is defined, silently undefine it.
If DIRECT_FORCE_DEBUG is define, show a warning and undefine it.
