Once the IVB and BYT work lands, I'll send patches to enable the other GL_OES_shader_io_blocks and GL_OES_geometry_shader on those platforms. I sent a couple minor nits on 4, 10, and 12. With or without those changes, the series is Reviewed-by: Ian Romanick <[email protected]> It would still be good for someone who actually understands (ha!) the miptree code to review too. > Jordan Justen (16): > main: Add MESA_VERBOSE=api support for glTexImage > main: Add MESA_VERBOSE=api support for glClearStencil > i965/hsw: Don't advertise more than 64 threads for compute shaders > i965/hsw: Adjust uploading default color for stencil surfaces > i965: Fix assert with multisampling and cubemaps > i965/gen7: Add R8_UINT stencil miptree copy for sampling > i965: Track that the stencil data was updated when clearing > i965: Track that the stencil data was updated when rendering > i965: Track that the stencil data was updated when using Tex*Image > i965: Add function to copy a stencil miptree to an R8_UINT miptree > i965/gen7: Copy stencil when sampling the stencil texture > i965/gen7: Use R8_UINT stencil copy when sampling the stencil texture > i965: Enable ARB_stencil_texturing for Haswell > i965: Enable ARB_texture_stencil8 for Haswell > i965: Enable OpenGLES 3.1 for Haswell > docs: Update stencil texturing & ES 3.1 status for i965 Haswell > > docs/GL3.txt | 6 +-- > docs/relnotes/12.1.0.html | 3 ++ > src/mesa/drivers/dri/i965/brw_clear.c | 8 +++ > src/mesa/drivers/dri/i965/brw_context.c | 44 +++++++++++------ > src/mesa/drivers/dri/i965/brw_sampler_state.c | 8 ++- > src/mesa/drivers/dri/i965/brw_wm_surface_state.c | 13 ++++- > src/mesa/drivers/dri/i965/gen7_misc_state.c | 1 + > src/mesa/drivers/dri/i965/intel_extensions.c | 7 ++- > src/mesa/drivers/dri/i965/intel_mipmap_tree.c | 63 > ++++++++++++++++++++++-- > src/mesa/drivers/dri/i965/intel_mipmap_tree.h | 16 ++++++ > src/mesa/drivers/dri/i965/intel_screen.c | 5 ++ > src/mesa/drivers/dri/i965/intel_tex_image.c | 3 ++ > src/mesa/drivers/dri/i965/intel_tex_subimage.c | 7 ++- > src/mesa/main/stencil.c | 3 ++ > src/mesa/main/teximage.c | 5 ++ > 15 files changed, 164 insertions(+), 28 deletions(-) _______________________________________________ mesa-dev mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/mesa-dev
