'-DHAVE_ALIAS' to DEFINES in the config file used for building. On the
linux-dri-x86 build, this cuts 4KB from libGL.so. HAVE_ALIAS is not
currently enabled in any of the configs.
an extension spec). It's not perfect, and it doesn't support certain
functions that other scripts here can (e.g., pixel functions). However,
it is a good start and has already proven useful to me.
glX_proto_send.py script. This eliminates ~600 lines of non-generated
code. With proper compiler optimization settings, it also decreases the
size of libGL.so by about 3KB.
glXChooseVisual() or glXChooseFBConfig() so that we handle the
GLX_DOUBLEBUFFER and GLX_STEREO tokens correctly.
Added some new error checking in those functions too.
1. Unlock hardware before aborting and dumping DMA buffers. Otherwise display system may deadlock.
2. Fix DMA init IOCTL call that got mixed up in one of the previous commits.
3. Fix AGP command alignment
like the old one was prone to collisions (different value of format field was
required for same values of t->format going in).
Now use a hash for these purposes - this got kfiresaver.kss and lesson06 workingfrom the same code.
* Only set scissor regs directly if drmMinor < 1
* Don't set texaddr to 0 when a texture unit is disabled. That would trigger
the tightened texture state check in the DRM if the texaddr and texdesc
registers were not emitted atomically.
the xf86drmVIA.[ch] files.
Bring in the IRQ handler and Ring buffer code, but ring buffer is disabled
as it is with the Xserver. It certainly locks up the CLE266.
This can be tested with lesson19 from NeHe.
This has also shown that the alpha code does not work - we pick up a red tint
for transparent pixels somewhere.
hardware. By also reversing the depth range this can compensate the loss
of accuracy of far objects caused by the projective transformation.
Software fallbacks work but are slightly slower since floats in a custom
(non IEEE) format have to be encoded and decoded. I havn't done anything
about polygon offsets yet. There doesn't seem to be an easy way do get
it right except making the offset unit as big as the lowest resolution
of depth values. For now float depth is disabled by default but can be
enabled through driconf (though I have seen only positive effects so
far).
