This is used in the upcoming fixed function shader_program generation,
and shader_program and ARB programs are together in this code until
both fragment and vertex ff get converted.
|
|
It fails on assertions if the key isn't actually present.
|

|

The drivers have been changed so that they behave as if all of the flags
were set. This is already implicit in most hardware drivers and required
for multiple contexts.
Some state trackers were also abusing the PIPE_FLUSH_RENDER_CACHE flag
to decide whether flush_frontbuffer should be called.
New flag ST_FLUSH_FRONT has been added to st_api.h as a replacement.
|
|
|
|
So that they don't have the driver-specific param and return type.
|
|
Only st/xorg used it and even incorrectly with regards to pipelined transfers.
|
|
Without this, EXT_texture_from_pixmap is trivially broken. With it,
it's merely subtly broken.

Since we're compiling/linking GLSL shaders we should check against
the shader uniform limits, not the legacy vertex/fragment program
parameter limits which are usually lower.
|
|
The gl_program_constants struct is for limits that are applicable to
any/all shader stages. Move the geometry shader-only fields into the
gl_constants struct.
Remove redundant MaxGeometryUniformComponents field too.
|
|
Without these checks we could create shaders with more samplers,
constants than the driver could handle. Fail linking rather than
dying later.
|
|
and rename them.

Need to flush rendering (or at least indicate that the rug might be getting
pulled out from underneath us) when a shader, buffer object or query object
is about to be deleted.
Also, this helps to tell the VBO module to unmap its current vertex buffer.

DMAs.

upload->offset is how much we used. upload->size is the whole buffer size.

With 3 pipes cards we need to align with NPOT values. This fixes:

I don't see a reason we need them.
|
|
The framebuffer cache flush should be implicit when calling
set_framebuffer_state.
There is no need to flush the command stream either.

This reverts commit 6d4e337f3890105c7d8a2f132412c137d2570d25.
The commit is incorrect. I'll rework it. Revert for now.

Tested by temporarily using util_clear even when not using the blitter.

u_blitter is lazy and doesn't fully clear it's stack-allocated fb.

Benefits:
- spares us a relocation.
- needed for zone rendering (if that ever happens).
- just awesome.
v2: Rename the debug option. Completely disabling the blitter is
required for Y tiling to work, so this option will cover other
code paths in the future.
v3: Implement suggestions by Jakob Bornecrantz.

Flushing the batch/hw backend doesn't invalidate the derived state.
So kill the unnecessary function calls and add an assert in
emit_hardware_state for paranoia.

With the new clear code this is possible (if the app call glClear
before drawing the first primitive).

The polygon stipple fallback does not have to be implemented in the
draw module (it doesn't need window coords, etc). Drivers can use
this utility and avoid sw vertex fallbacks if pstipple is enabled.
Note: this is WIP and not used by any driver yet.

The gc var would be NULL if called from line 238. Instead, get
the opcode from __glXSetupForCommand(dpy) as done in other places.
And remove the unused gc parameter.
Fixes a bug reported by "John Doe" on 3/9/2011.
NOTE: This is a candidate for the 7.10 branch.
|
|
Make sure we only upload parts of vertex arrays that are actually used
by a draw command.

This fd gets passed in from outside, closing it causes the X.org server
to crap out when the driver doesn't identify the chipset.

This is an expected behavior when we're testing for the presence of
new kernel features.

Improves performance of a hacked-up scissor-many (to reuse a small set
of scissors instead of blowing out the cache, and then to run 100x
more iterations so it actually took some time) by 3.6% +/- 1.2% (n=10)

Add ensure_sanity checks.
Fix a bug which caused us to misplace entries adding to a full cache.
|
|
Add linear probing on collisions.
Expand entry array by a fixed scale (currently 2) to help avoid
collisions.
Use a LRU approach to ensure that the number of entries stored in the
cache doesn't exceed the requested size.
|

I need to be able to remove entries from util_cache caches. This change
enables that functionality.

Do that later on when we set up the hwtnl state instead.
This addresses a problem when we drop the uploaded copy due to a vb
size change, it will remain referenced in svga->curr.vb[], and the
new contents of the vb will never be uploaded.

This is a follow-up to commit b39bccbd4ed71e9585da4cf5acf7b887b2e90899.
