Fixes piglit glsl-vs-if-bool and progs/glsl/twoside, and will likely be
useful for the looping code.
Bug #18992
|
|
Previously, we'd be branching based on whatever condition code happened to be
laying around.
|

|
both for normal and cube textures, this fixes demos/multiarb
(with 6 enabled texture units) and fixes #23142.

|
|
|
another case of image never matching miptree in case of compressed textures
|
|
similar to the radeon code.
passes tests/texcompsub
|
|
use glCompressedTexSubImage2DARB also with xoffset by splitting into 3 calls
in total. Dunno if the top/bottom reversal is intentional but leave as is.

I was getting tired of doing the dance of INTEL_DEBUG=batch, copying it out,
and running intel-gen4disasm on it.
|
|
There's a bunch of stuff from gen4asm and gpu-tools that we probably want
to make into a library instead of cargo-culting it around.

Bug #20821
|
|
Instead of relying on the Makefile to always generate $(TOP)/$(LIB_DIR),
just have mklib handle creating the directory. This should fix any races
when using parallel make.

This avoids sending a bad buffer address to the GPU due to programmer error,
and is permitted by the ARB_vbo spec. Note that we still have the opportunity
to dereference past the end of the GPU, because we aren't clipping to a
correct _MaxElement, but that appears to be harder than it should be. This
gets us the 90% solution.
Bug #19911.

See comment on Vertex URB Entry Read Length for VS_STATE.
This, combined with the previous three commits, fixes #22945.
|
|
This fix is just from code and docs inspection, but it may fix hangs on
some applications.
|
|
It appears that sometimes Mesa (and I suppose a VS could as well) emits
a program which references no vertex data, and thus we end up with
nr_enabled == 0 even though some VBs are enabled. We'd end up emitting
VB/VE packet headers of 0xffffffff in that case, leading to GPU hangs.
Bug #22945 (wine with an uncompiled VS)
|
|
The code duplication bothered me.
|
|
somehow, this change was missed on the last checkin
|
|
- Added specifications for the extensions GL_APPLE_flush_buffer_range and
GL_APPLE_texture_range
- EXT_framebuffer_object.xml strangely held specifications for both
the GL_EXT_framebuffer_object extension and the GL_EXT_texture_array
extension. Split out the GL_EXT_texture_array data into its own
file.

- fix not respecting required hardware stride with compressedTexImage -
this fixes #22615.
- make sure correct stride is used in various places
- fix stored miptree never matching with a TexImage call with compressed
texture
- don't always store data with compressedtexsubimage at offset 0,
and actually use the supplied pixel data... (untested)
- make sure rows for compressed texture handling are rounded up not down
Note that trying to access stored compressed textures in hardware miptrees
from core mesa (get_compressed_teximage, swrast fallbacks) can't work correctly,
since RowStride isn't really set to anything useful, plus some places (at least
get_compressed_teximage) assume this data has native stride and no padding.

(corresponding fix to the intel driver one)
|
|
The comment disagreed with the code, and nicely drew my eyes to what was
going wrong.
Bug #21774 (blender)
Bug #21788 (readpix)

This fixes jerkiness in doom3 and other apps since the kernel change to
throttle less absurdly, which led to a thundering herd of frames.
Because this is a rather minimal fix, there is at least one downside: If
the whole scene completes in one batchbuffer, we'll end up stalling the GPU.
Thanks to Michel Dänzer for suggesting using glFlush to signal frame end
instead of going to all the effort of adding a new DRI2 extension.

Funny thing is I annotated this dependency in
e5f63c403b767f9974e8eb5d412c012b8a69287f, but didn't actually use it.

EGL_TEXTURE_FORMAT and EGL_TEXTURE_TARGET should default to
EGL_NO_TEXTURE.

Now that a current surface points back to its binding context, and a
current context points back to its binding thread, make sure there is no
dangling pointers. This commit reworks eglMakeCurrent, adds more checks
to avoid stealing context or surfaces from another thread, and correctly
destroys unlinked context and surfaces.

IsBound tells if a context or surface is current. What it does not tell
is, to which thread a context is current, or to which context a surface
is current. This commit replaces IsBound by a pointer to the binding
thread or context.
