Mesa is an open-source 3D graphics library that provides the commonly-used DRI and Gallium3D open-source Linux graphics drivers.

Today's Activity

tnl: Try not to botch index buffer munging when start > 0.
Kenneth Graunke: Commit 4c751ad67aa2bbde5897030495f86e31c9e1fda7 (vbo/dlist: use a shared index buffer) caused multiple draws to use the same index buffer, and began setting the primitive's `start` field to the offset needed to access the right portion of the index buffer. Unfortunately, t_rebase_prims completely botches handling this case.

Yesterday's Activity

radv: flush L2 for images affected by the pipe misaligned issue on GFX10+
Samuel Pitoiset: In some rare cases, L2 needs to be flushed if an image is affected by the pipe misaligned issue.

radv: enable TC-compat HTILE for D16S8 on GFX9+
Samuel Pitoiset: I don't know why this wasn't enabled but I think it should be.

radv: enable TC-compat HTILE with D32S8 and MSAA on GFX9+
Samuel Pitoiset: Only GFX8 has some depth/stencil resolve failures.

Other Activity This Week

pan/bi: Add w0 to the 'h01' swizzle bucket
Icecream95: A number of instructions, such as LOAD.

panfrost: Add a sysval for local_work_dim
Icecream95: Fixes Piglit test get-work-dim.

radv: Do not use a pipe offset for aliased sparse images
Bas Nieuwenhuizen: Otherwise the offset might not match between the images that are aliased.

radeonsi: add a specialized function for CP DMA L2 prefetch
Marek Olšák: This radically simplifies the code to decrease CPU overhead in si_draw_vbo.

android: freedreno/hw/isa: Add description of ir3 ISA
Mauro Rossi: Necessary to build libir3decode and libir3encode for Android

zink/codegen: make 'struct' optional in Version
Hoe Hao Cheng

lima: introduce fs and vs shader cache
Erico Nunes: Some opengl features require shader recompilation to be implemented in the mali400 and can only be detected at draw time.

freedreno/a2xx: add RB perfcounter 1-3
Joel Linn: Xenos driver reads four perf counters in total.

freedreno/a2xx: fix/add RBBM perfcounter
Joel Linn: Xenos driver read two perf counters and their order is also different.

glsl: only expose int64 atomics when extension is enabled
Ilia Mirkin: This limits the exposure of these functions to when the extension is available.

freedreno/a6xx: Add r2d support for GMEM resolves
Rob Clark: For cases where we need to do an MSAA resolve that BLIT events cannot handle, fall back to CP_BLIT (r2d)

ac/surface: Fix GFX9 sparse mip info
Bas Nieuwenhuizen: Used the wrong offset & pitch for gfx9.

device-select-layer: update for vulkan 1.2
Dave Airlie: The vulkan loader doesn't load layers for apps that require a newer version of vulkan, so this layer didn't get loaded for vulkan 1.2 apps. I would like to just stick 1.09 in there but it might be worth validating it works at new version of vulkan I suppose and the major doesn't revise that often Fixes: 9bc5b2d169d3 ("vulkan: add initial device selection layer.

util: Fix pointer to integer conversion error when using libunwind
Jeremy Huddleston Sequoia: ../src/util/u_debug_stack.c:97:20: error: incompatible pointer to integer conversion assigning to 'unw_word_t' (aka 'unsigned long') from 'void *' [-Werror,-Wint-conversion] pip.unwind_info = NULL; ^ ~~~~ 1 error generated.

freedreno/ir3/parser: add cat7 support
Danylo Piliaiev

gallium/ntt: Add support for store_per_vertex_output
Eric Anholt: Needed by virgl and r600 to use NTT.

zink: implement passthrough tcs shader injection
Mike Blumenkrantz: GL allows the pipeline to "infer" a tcs shader if a tes shader is bound using API-specified default values for gl_TessLevelOuter and gl_TessLevelInner, but VK requires that both shaders be explicitly present to handle this, create a generic tcs which translates all vs outputs to invocation-based arrays and copy the appropriate value to the expected tes input array location.

ci: remove all tracie remains
Andres Gomez
