after we check the buffer
|
|
a new cmdbuf, to ensure that state wasn't lost across UNLOCK/LOCK pairs (in the
case of context switching). This was rather inefficient. Instead, after
flushing a cmdbuf, mark the state as needing to be saved on UNLOCK. Then, at
the beginning of flushing a cmdbuf, if we actually have lost the context, go
back and emit a new cmdbuf with the full set of state, before continuing with
the cmdbuf flush. Also, remove the dirty/clean atom lists, since atoms are
emitted in a fixed order these days, and go with a simpler single list.
Provides a 14% improvement in ipers performance in my tests, along with other
apps.

support in the r200 driver. Both extensions can be enabled via
options, GL_ARB_vertex_program is on by default, GL_NV_vertex_program
off. Option descriptions are in german, english and french.

last commit. I've been convinced by keithw that it's sufficient, and put a note
in the code about it.
Close another race for state in the Clear functions. I made the situation worse
in my last commit, but this should fix things. Might be a slight performance
hit, which could be regained by splitting the R*_FIREVERTICES calls in r*Clear
up so that the EmitState doesn't happen in a separate new cmdbuf.

errors on r100 and rendering errors and hangs on r200 (same for R100 without
OLD_PACKETS).
If a command buffer filled after some state (EmitState or a VBPNTR write) was
emitted, the lock was grabbed, the buffer flushed, a new buffer prepared, and
the lock dropped. Another client could come in, set its own state as part of
rendering, and when the first client flushed the rendering commands depending
on the previous state, it got the 2nd client's state. This is fixed by checking
for enough space before beginning a set of state emits and rendering, and
flushing the buffer first if so. This guarantees that the buffer won't wrap.
Also, move the "lost_context = 1" from the end of cmdbuf flushing to
UNLOCK_HARDWARE for clarity (at a minimum) that any time the lock is dropped,
state may get overwritten. We don't have enough information at the point of the
LOCK_HARDWARE to reset our state to the last UNLOCK_HARDWARE point in the case
that we did lose our context, but saving the information to rebuild that state
may be a useful optimization (ipers data suggests up to 5%).

drivers when DRI_NEW_INTERFACE_ONLY is defined. #ifndef it away in
that situation.
Add a new function, driCheckDriDdxDrmVersion2, that is passed in the
version information that is already supplied to __driCreateNewScreen.
Part of the reason that information is supplied to
__driCreateNewScreen is so that the driver doesn't have to make those
calls to get it!
Modify all drivers that support the new interface to use the new
function instead of the old. As soon as all drivers support the new
interface, driCheckDriDdxDrmVersion can be removed.

The gl_texture_format struct now has a StoreTexImageFunc that's called
by glTex[Sub]Image[123]D to convert the user's texture data into the
specific texture format layout. Now it's much easier to add new texture
formats (like the 16/32-bit floating point formats).
The texutil.[ch] and texutil_tmp.h files are obsolete.
