2016-11-23i965: Fix a mistake from porting the URB allocation code to arrays.Kenneth Graunke1-1/+1
Commit 6d416bcd846a49414f210cd761789156c37a7b3e (i965: Use arrays in Gen7+ URB code.) introduced a regression which caused us to fail to allocate all of our URB space. - total_wants -= ds_wants; + total_wants -= additional; The new line should have been total_wants -= wants[i]. Fixes a large performance regression in TessMark.

Most of the 3-D engine Kaby Lake is identical to Sky Lake. However, there are a few small differences that we need to be able to detect. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net> Reviewed-by: Matt Turner <mattst88@gmail.com>

2016-11-09mesa: Fix pixel shader scratch space allocation on Gen9+ platforms.Kenneth Graunke1-14/+19
We had missed a bit of errata - PS scratch needs to be computed as if there were 4 subslices per slice, rather than 3. Skylake Broxton Kabylake GT1 GT2 GT3 GT4 2x6 3x6 GT1 GT1.5 GT2 GT3 GT4 Actual Slices 1 1 2 3 1 1 1 1 1 2 3 Total Subslices 3 3 6 9 2 3 2 3 3 6 9 Subsl. for PS Scratch 4 4 8 12 4 4 4 4 4 8 12 Note that Skylake GT1-3 already worked because we allocated 64 * 9 (trying to use a value that would work on GT4, with 9 subslices), and the actual required values were 64 * 4 or 64 * 8. However, all others (Skylake GT4, Broxton, and Kabylake GT1-4) underallocated, which can lead to scratch writes trashing random process memory, and rendering corruption or GPU hangs. Fixes GPU hangs and rendering corruption on Skylake GT4 in shaders that spill. Particularly, dEQP-GLES31.functional.ubo.all_per_block_buffers.* now runs successfully with no hangs and renders correctly. This may fix problems on Broxton and Kabylake as well.

2016-10-05i965/l3: Add explicit way size calculation for bxtBen Widawsky1-1/+3
There should be no functional change here because Broxton and CHV are both gt1. Without this code however, it might seem like broxton support is missing. While here, put the gt1 check in front to hopefully short-circuit the condition for the mobile cases.

2016-09-23intel/i965: make gen_device_info mutableLionel Landwerlin2-7/+6
Make gen_device_info a mutable structure so we can update the fields that can be refined by querying the kernel (like subslices and EU numbers). This patch does not make any functional change, it just makes gen_get_device_info() fill a structure rather than returning a const pointer.
