[i915] Bug #13634: Fix bugs in 945 cube mipmap layout.
The most egregious, and the one the bug report and failure in the cubemap
demo were about was introduced with intel_mipmap_pitch_align(), where a
"* 2" for the pitch calculation was lost. The base size < 32 case also
failed to align, which may have caused problems with render to texture.
Another bug would have broken 2x2/1x1 base mipmap levels by placing the
data where the hardware wouldn't look for it.
Other bugs remain with the layout of the small mipmap faces (hardware looks
for them in X,Y,Z,-X,-Y,-Z order along the bottom row, but we lay them out
X,-X,Y,-Y,Z,-Z).
glx: Add isDirect back to __GLXcontextRec. It is needed
to check whether oldGC is used for direct rendering in
function MakeContextCurrent. However it is possible
oldGC->driContext is already freed. fix bug #14926.
mesa: fix emit_clamp() so that we don't use an output register as temporary
IR_CLAMP is decomposed into OPCODE_MIN+OPCODE_MAX. Allocate a temporary
register for the intermediate value so we don't inadvertantly use an output
register (which are write-only on some GPUs).
Move make install logic for libGL back into src/mesa/Makefile.
This makes make install work again for non-glx libGL implementations.
The make install logic is split into three sub-targets: install-libgl,
install-osmesa, install-drivers. The install target in src/glx/x11
is then implemented using the src/mesa make install-libgl rule.
Thanks to Dan Nicholson for pointing out the breakage.
autoconf: Add autogen.sh from Xorg for easier setup from git
The defacto method to rebuild the autotools and run the generated
configure is an autogen.sh script. It is much more discoverable than the
custom `make configure' used here. The Makefile targets are still useful
for creating tarballs, though. This autogen.sh is copied from Xorg.
DRI2: Make setTexBuffer take a __DRIdrawable instead of a BO handle.
This fixes a problem where texturing from the same Pixmap more than
once per batchbuffer would hang the DRI driver. We just use the region
associated with the front left renderbuffer of the __DRIdrawable for
texturing, which avoids creating different regions for the same BO.
This change also make GLX_EXT_texture_from_pixmap work for direct
rendering, since tracking the __DRIdrawable -> BO handle now uses
the standard DRI2 event buffer. Of course, DRI2 direct rendering
doesn't exist yet.
Finally, this commit bumps the DRI interface version again, accounting
for the change in the DRI_TEX_BUFFER extension and the change in
commit 0bba0e5be7 to pass in the
event buffer head index on drawable creation.
__dri2ParseEvents() would determine the kind of event, but then call
UpdateBuffer() in either case, and UpdateBuffer() would then have to
figure that out again to dispatch to HandleBufferAttach() or
HandleDrawableConfig(). Pretty pointless.
DRI2: Pass the context instead of the screen to __dri2ParseEvents().
Makes a lot more sense, since the screen is always implicit in the
DRI drawable, but it may not be possible to track down a context from
just a drawable.
