the driver used to overwrite grf0 then use implicit move by send instruction
to move contents of grf0 to mrf1. However, we must not overwrite grf0 since
it's still used later for fb write.
Instead, do the move directly do mrf1 (we could use implicit move from another
grf reg to mrf1 but since we need a mov to encode the data anyway it doesn't
seem to make sense).
I think the dp_READ/WRITE_16 functions may suffer from the same issue.
While here also remove unnecessary msg_reg_nr parameter from the dataport
functions since always message register 1 is used.

This allows us to return the unused portion of the dma buffer
to the allocator instead of wasting nearly 16k a pop.

still always enable max, but the right values this time.
More work should probably be done for saner limits without mm, and/or
dri conf option allow_large_textures (which is ignored) removed.
3D limit on r100 is pretty arbitrary as still handled by swrast anyway.
Also fix r300 limits (except 3d I've no idea what the max is anyway so
keep using mesa default).

This was already correct in the GEM code

I haven't fixed all the regressions yet, and it'll be easy to re-enable when
the known problems are fixed.

It's the last addressable byte, not the byte after the end of the buffer.

I noticed this when this MI_FLUSH showed up in IPEHR for the ut2004 hang.
Not setting the reserved bit didn't help, though.

Fixes assertion failure on norsetto shadow mapping demo.

Fixes shadowtex.c. And an assert is added to catch this sooner next time.

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.
|
|
I was in the midst of fixing some blitting-with-Y-tiled issues when I
noticed this. Hopefully PBO usage will be a little more robust, as a
result.

glsl compiler will not generate OPCODE_SWZ, and as a first step it would
be translated away to a MOV anyway (why?), but later internally this opcode is
generated (for EXT_texture_swizzling).

Fixes regression in dd26899ca39111e0866afed9df94bfb1618dd363 that also
affected some PBO operations.

We could have mapped the wrong set of draw buffers. Noticed while looking
into a DRI2 glean ReadPixels issue.
|

This fixes a regression in region read performance that came in with the
texture tiling changes. Ideally we'd have an access flag coming in so we
could also use bo_map_gtt for writing, like we do for buffer objects.

The CALL_DrawArrays was leaking the clear's primitives into the display
list with GL_COMPILE_AND_EXECUTE. Use _mesa_DrawArrays instead, which
doesn't appear to leak. Fixes piglit dlist-clear test.

pbo might be system buffer based or attached to another region. Call
intel_bufferobj_buffer to make sure pbo has a buffer of its own.

intel_bufferobj_subdata is called to migrate data from sys_buffer, and
it expects only one of buffer or sys_buffer is non-NULL.

need to pass target parameter to radeon_teximage/radeon_subteximage functions
otherwise mipmap generation for cube maps can't work (assert/segfault in
_mesa_generate_mipmap)
|

Initialize all driver function hooks before calling _mesa_initialize_context(),
and handle all buffer objects in intel_buffer_object().
Fixes assertion failure when running glxinfo.

drm cmd checker would refuse cube emits
also fix an issue in the cs path which would calculate the register
offset off by one dword.
Only same testing done as original code (none except compile tested).

drm cmd checker rightfully fell over any cube emit

Fixes #22181. R200 requires this since DP4 is used in hw tnl mode.
R300 prefers it (should be faster due to no instruction dependencies), but
both methods should be correct (when sw tcl is used though, MUL/MAD might
be faster). Probably doesn't make much difference for R100 since vertex progs
are executed in software anyway, but let's just keep it the same there too.

With 1D textures, GL_TEXTURE_WRAP_T should be ignored (only
GL_TEXTURE_WRAP_S should be respected). But the i965 hardware
seems to follow the value of GL_TEXTURE_WRAP_T even when sampling
1D textures.
This fix forces GL_TEXTURE_WRAP_T to be GL_REPEAT whenever 1D
textures are used; this allows the texture to be sampled
correctly, avoiding "imaginary" border elements in the T direction.
This bug was demonstrated in the Piglit tex1d-2dborder test.
With this fix, that test passes.

One warning message:
drm_i915_getparam: -22
was still being sent to fprintf(). This causes all Piglit tests to fail,
even with MESA_DEBUG=0.
Using _mesa_warning() to emit the message allows the general Mesa controls
for messages like this to be applied.

When out of memory (in at least one case, triggered by a longrunning
memory leak), this code will segfault and crash. By checking for the
out-of-memory condition, the system can continue, and will report
the out-of-memory error later, a much preferable outcome.

This saves doing swtnl from uncached memory, which is painful. Improves
clutter test-text performance by 10% since it started using VBOs.
