It's faster. Not only is the memcpy more efficiently performed in the
kernel (making up for the system call overhead), but by not using mmap
we remove the greater overhead of tracking the vma of every batch.
And it means we can read back from the batch buffer without incurring
the cost of a uncached read through the GTT.

This provides the optimizer with hints about code hotness, which we're
quite certain about for debug printouts (or, rather, while we
developers often hit the checks for debug printouts, we don't care
about performance while doing so).

Need to bring back correct fb write with header to set pixel
write mask. Fallback for now.

Fix this GCC warning.
intel_pixel_bitmap.c: In function 'intelBitmap':
intel_pixel_bitmap.c:343: warning: implicit declaration of function '_mesa_meta_Bitmap'

The meta code is more general than mine, and appears to pass the same
sets of tests (piglit + some oglconform).

Add context.h for NEED_SECONDARY_COLOR symbol.

This uses a stamp mechanisms to mark the DRI drawable as invalid.
Instead of immediately updating the buffers we just bump the drawable
stamp and call out to DRI2GetBuffers "later".
"Later" used to be at LOCK_HARDWARE time, and this patch brings back
callouts at the points where we used to call LOCK_HARDWARE. A new function,
intel_prepare_render(), is called where we used to call LOCK_HARDWARE,
and if the buffers are invalid, we call out to DRI2GetBuffers there.
This lets us invalidate buffers only when notified instead of on
every glViewport() call. If the loader calls the DRI invalidate
entrypoint, we disable viewport triggered buffer invalidation.
Additionally, we can clean up the old viewport mechanism a bit,
since we can just invalidate the buffers and not worry about
reentrancy and whatnot.

Noticed by clang.

bcbfda71b03303d3f008a6f3cf8cb7d9667bf8d2 left out many blit paths.
This fixes up more of them to get Blender to work again.

Need to push texture state and polygon state too.
Fixes rendering glitches seen in progs/demos/engine when changing
the rendering mode (wireframe, texture modes).
This makes bitmap rendering a little slower, unfortunately.

Move all the metaops to a dri_metaops file and port radeon/intel
to use the new common meta ops code.
|
|
RasterPos[2] is already sent through the window transform, which includes
DepthRange handling. So make DepthRange for the metaops a noop.
Fixes a failure in oglconform depthrange.c

We would have to build the program with the appropriate fog mode, and
also supply the fog coordinate if appropriate.
Bug #19413.

This is somewhat nasty, but we need to do Y-tiled depth for FBO support.
May help with corruption and hangs since enabling texture tiling, and
since switching depth textures to Y tiled.
Fixes piglit depthtex.c on 965.

Fixes oglconform zbfunc.c and pxtrans-cidraw.c, at least.

Make this be its own function for setup/teardown of the binding of these
texcoords. No performance difference in the engine demo (I just felt dirty
not using a VBO for this), and I think it should be more resilient to
interference from current GL state.

Found while debugging cairo-gl.

When we use the do_blit_bitmap() function, it seems the fragment Z is always
1.0. If depth testing is on, that means that bitmap fragments are often
occluded by other rendering. So, the bitmap doesn't appear even if
rasterpos.Z==0.
The fix is to use the intel_texture_bitmap() path when depth testing is on.
Also, fix the incorrect Z coordinate. It needs to be an NDC value in [-1,1].

The DrawPixels path was missing glViewport care, so blender's toolbar icons
would go to the wrong places.
Bug #19118.
|
|
This lets us avoid software fallbacks when clients forget to turn some state
off (engine demo) or just do crazy things to test conformance (OGLC).
This should probably be brought into mesa generic code so other drivers can
make use of it.

Bug #18914. Fixes fbo_firecube hang due to drawing outside the FBO bounds.
Thanks to Pierre Willenbrock for debugging the issue.
