From a75c6163e605f35b14f26930dd9227e4f337ec9e Mon Sep 17 00:00:00 2001 From: Tom Stellard Date: Fri, 6 Jan 2012 17:38:37 -0500 Subject: radeonsi: initial WIP SI code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit adds initial support for acceleration on SI chips. egltri is starting to work. The SI/R600 llvm backend is currently included in mesa but that may change in the future. The plan is to write a single gallium driver and use gallium to support X acceleration. This commit contains patches from: Tom Stellard Michel Dänzer Alex Deucher Vadim Girlin Signed-off-by: Alex Deucher The following commits were squashed in: ====================================================================== radeonsi: Remove unused winsys pointer This was removed from r600g in commit: commit 96d882939d612fcc8332f107befec470ed4359de Author: Marek Olšák Date: Fri Feb 17 01:49:49 2012 +0100 gallium: remove unused winsys pointers in pipe_screen and pipe_context A winsys is already a private object of a driver. ====================================================================== radeonsi: Copy color clamping CAPs from r600 Not sure if the values of these CAPS are correct for radeonsi, but the same changed were made to r600g in commit: commit bc1c8369384b5e16547c5bf9728aa78f8dfd66cc Author: Marek Olšák Date: Mon Jan 23 03:11:17 2012 +0100 st/mesa: do vertex and fragment color clamping in shaders For ARB_color_buffer_float. Most hardware can't do it and st/mesa is the perfect place for a fallback. The exceptions are: - r500 (vertex clamp only) - nv50 (both) - nvc0 (both) - softpipe (both) We also have to take into account that r300 can do CLAMPED vertex colors only, while r600 can do UNCLAMPED vertex colors only. The difference can be expressed with the two new CAPs. ====================================================================== radeonsi: Remove PIPE_CAP_OUTPUT_READ This CAP was dropped in commit: commit 04e324008759282728a95a1394bac2c4c2a1a3f9 Author: Marek Olšák Date: Thu Feb 23 23:44:36 2012 +0100 gallium: remove PIPE_SHADER_CAP_OUTPUT_READ r600g is the only driver which has made use of it. The reason the CAP was added was to fix some piglit tests when the GLSL pass lower_output_reads didn't exist. However, not removing output reads breaks the fallback for glClampColorARB, which assumes outputs are not readable. The fix would be non-trivial and my personal preference is to remove the CAP, considering that reading outputs is uncommon and that we can now use lower_output_reads to fix the issue that the CAP was supposed to workaround in the first place. ====================================================================== radeonsi: Add missing parameters to rws->buffer_get_tiling() call This was changed in commit: commit c0c979eebc076b95cc8d18a013ce2968fe6311ad Author: Jerome Glisse Date: Mon Jan 30 17:22:13 2012 -0500 r600g: add support for common surface allocator for tiling v13 Tiled surface have all kind of alignment constraint that needs to be met. Instead of having all this code duplicated btw ddx and mesa use common code in libdrm_radeon this also ensure that both ddx and mesa compute those alignment in the same way. v2 fix evergreen v3 fix compressed texture and workaround cube texture issue by disabling 2D array mode for cubemap (need to check if r7xx and newer are also affected by the issue) v4 fix texture array v5 fix evergreen and newer, split surface values computation from mipmap tree generation so that we can get them directly from the ddx v6 final fix to evergreen tile split value v7 fix mipmap offset to avoid to use random value, use color view depth view to address different layer as hardware is doing some magic rotation depending on the layer v8 fix COLOR_VIEW on r6xx for linear array mode, use COLOR_VIEW on evergreen, align bytes per pixel to a multiple of a dword v9 fix handling of stencil on evergreen, half fix for compressed texture v10 fix evergreen compressed texture proper support for stencil tile split. Fix stencil issue when array mode was clear by the kernel, always program stencil bo. On evergreen depth buffer bo need to be big enough to hold depth buffer + stencil buffer as even with stencil disabled things get written there. v11 rebase on top of mesa, fix pitch issue with 1d surface on evergreen, old ddx overestimate those. Fix linear case when pitch*height < 64. Fix r300g. v12 Fix linear case when pitch*height < 64 for old path, adapt to libdrm API change v13 add libdrm check Signed-off-by: Jerome Glisse ====================================================================== radeonsi: Remove PIPE_TRANSFER_MAP_PERMANENTLY This was removed in commit: commit 62f44f670bb0162e89fd4786af877f8da9ff607c Author: Marek Olšák Date: Mon Mar 5 13:45:00 2012 +0100 Revert "gallium: add flag PIPE_TRANSFER_MAP_PERMANENTLY" This reverts commit 0950086376b1c8b7fb89eda81ed7f2f06dee58bc. It was decided to refactor the transfer API instead of adding workarounds to address the performance issues. ====================================================================== radeonsi: Handle PIPE_VIDEO_CAP_PREFERED_FORMAT.
