Drop a bunch of unused arguments from intel_create_renderbuffer() and
introduce intel_renderbuffer_set_region() to set the region for
a renderbuffer.

This may allow better concurrency (noop in openarena performance now), but is
also important for the previous commit -- otherwise, we may end up with
BufferData, draw_prims, BufferData and the draw_prims would use the new VBO
data instead of old. This could still occur with user-supplied VBOs and poor
use of MapBuffer without BufferData.
|
|
The comment about (vbo)_exec_api.c appeared to be stale, as the VBO code seems
to only use non-named VBOs (not actual VBOs) or freshly-allocated VBO data.
This brings a 2x speedup to openarena, because we can submit nearly-full
batchbuffers instead of many 450-byte ones.
|
|
This allows us to avoid re-emitting some state when validate_state happens
multiple times per batchbuffer. Even though we flush batch per primitive
currently, that may still happen already if the primitive changed (this should
probably be fixed as well).
|
|
Both drivers have ended up relying on lost_hardware being called after each
batch buffer, so update the name. This removes one of the calls on 965 whic
h was outside of the batchbuffer handling code and just duplicating what had
already happened through batchbuffer handling.
|
|
|
|
In particular, batch buffers are no longer flushed when switching from
CLIPRECTS to NO_CLIPRECTS or vice versa, and 965 just uses DRM cliprect
handling for primitives instead of trying to sneak in its own to avoid the
DRM stuff. The disadvantage is that we will re-execute state updates per
cliprect, but the advantage is that we will be able to accumulate larger
batch buffers, which were proving to be a major overhead.

Each array element is now a BUFFER_x token rather than a BUFFER_BIT_x bitmask.
The number of active color buffers is specified by _NumColorDrawBuffers.
This builds on the previous DrawBuffer changes and will help with drivers
implementing GL_ARB_draw_buffers.
|
|
These fields are no longer indexed by shader output. Now, we just have
a simple array of renderbuffer pointers.
If the shader writes to gl_FragData[i], send those colors to the N
_ColorDrawBuffers. Otherwise, replicate the single gl_FragColor (or
the fixed-function color) to the N _ColorDrawBuffers.
A few more changes and simplifications can follow from this...

rendering. fix #12786

By avoiding the repeated relocation buffer creation/map/unmap/destroy for each
new batch buffer, this improves OpenArena framerates by 30%. Caching batch
buffers themselves doesn't appear to be a significant performance win over
this change.
|
|
We have two consumers of relocations. One is static state buffers, which
want the same relocation every time. The other is the batchbuffer, which gets
thrown out immediately after submit. This lets us reduce repeated computation
for static state buffers, and clean up the code by moving relocations nearer
to where the state buffer is computed.

This reverts commit 8bb9ae3693362a302206255c61f512d942df9bbf.
Validating our kernel buffers with the caching off in flags but on in mask
means that the kernel migrates the buffer to be uncached, which is undesired.
|
|
|
|
The 'mask' value used in the validation operation specifies which of the
'flags' bits are being modified. Buffer validation wants to pass the memory
type and access mode (rwx) to the kernel so that the buffer will be placed
correctly, and so that the right kind of fence will be created (read vs
write). That means we actually want a constant mask for these operations,
and not something computed from the bits coming in. The constant we want is
DRM_BO_MASK_MEM | DRM_BO_FLAG_READ | DRM_BO_FLAG_WRITE | DRM_BO_FLAG_EXE.
|
|
Without this, the WM binding tables would all collide, for example. Improves
openarena performance by around 2%.

this is correct, there is another issue with sw fallbacks
This reverts commit cc50edbca2fd3111f9987d4117fa6656599d79dc.

Also add some extra tests to the shader_api regression tests
|
|
|
|
- return GL_INVALID_OPERATION instead of GL_INVALID_VALUE if location is bad
- correct the type-checking of uniforms from my previous commit
- accept location of -1 in _mesa_uniform_matrix
|
|
- fix sizes for GL_FLOAT_MAT2x3 and GL_FLOAT_MAT4x3 in sizeof_glsl_type
- fix size returns in _mesa_get_active_attrib
- fix out-of-bounds array access to vec_types in _mesa_get_active_attrib
- fix queries of matrix uniforms in _mesa_get_uniformfv
- fix _mesa_get_uniformfv to only return one base, even from an array
- allow location == -1 in _mesa_uniform
- validate types in _mesa_uniform
- allow array overruns in _mesa_uniform
