I've also written a test to check the compressed cubemaps rendering (we already had tests for the Get functions, and compressed mipmaps, so this case was the only one missing). The patch is here (compressed-cubemap test): https://patchwork.freedesktop.org/series/54880/ While working on the test I found an issue with TexImage2D and some other compressed formats (like BPTC), and I wrote another test (included in the same patch) that points it out (see the cover letter). Another problem I hit while working on the cubemap test is described here (I found it by calling glViewport with invalid values accidentally): https://bugs.freedesktop.org/show_bug.cgi?id=108999 I've sent a small patch for it, but so far there was no reply: https://patchwork.freedesktop.org/patch/267292/ I'd really appreciate it if you could take some time to look at these 3 issues. Thank you very much in advance, Eleni ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
[Mesa-dev] [PATCH 0/8] i965: improved the support for ETC2 formats on Gen 7
Intel Gen7 GPUs don't have native support for ETC2 formats. We store the ETC2 images as RGBA in order to render them. This is a problem for GetCompressed* functions that should return compressed pixel values but return instead RGBA. With these patches, we store the compressed image data in the main image mipmap tree and we use a secondary mipmap tree to store the RGBA values for the rendering. We perform a lazy update every time that the main miptree changes. Fix: KHR-GL46.direct_state_access.textures_compressed_subimage Eleni Maria Stea (8): i965: Removed assertions from intel_miptree_map_etc i965: r8stencil_mt/needs_update renamed to shadow_mt/needs_update i965: Faking the ETC2 compression on Gen < 8 GPUs using two miptrees. i965: Update the shadow miptree from the main to fake the ETC2 compression i965: Fixed the CopyImageSubData for ETC2 on Gen < 8 i965: Added support for ETC2 mipmaps i965: Added support for ETC2 texture arrays on Gen7 i965: Enabled the OES_copy_image extension on Gen 7 GPUs src/mesa/drivers/dri/i965/brw_draw.c | 3 + .../drivers/dri/i965/brw_wm_surface_state.c | 35 +++- src/mesa/drivers/dri/i965/intel_extensions.c | 18 +- src/mesa/drivers/dri/i965/intel_mipmap_tree.c | 168 +++--- src/mesa/drivers/dri/i965/intel_mipmap_tree.h | 24 ++- src/mesa/drivers/dri/i965/intel_tex_image.c | 45 - src/mesa/main/texstore.c | 92 +- src/mesa/main/texstore.h | 9 + 8 files changed, 315 insertions(+), 79 deletions(-) -- 2.19.0 ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
