* meta/generate_mipmap: Only modify the draw framebuffer binding in ↵Ian Romanick2015-11-161-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | fallback_required Previously GL_FRAMEBUFFER was used. However, if GL_EXT_framebuffer_blit is supported (note: it is supported by every Mesa driver), this is *sometimes* an alias for GL_DRAW_FRAMEBUFFER (getters) and *sometimes* an alias for *both* GL_DRAW_FRAMEBUFFER and GL_READ_FRAMEBUFFER (setters). As a result, the code saved one binding but modified both. If the bindings were different, the GL_READ_FRAMEBUFFER would be incorrect on exit. Fixes the piglit fbo-generatemipmap-versus-READ_FRAMEBUFFER test. Ideally this function would use DSA functions and not modify the binding at all. However, that would be a much more intrusive change because _mesa_meta_bind_fbo_image would also need to be modified. _mesa_meta_bind_fbo_image has a lot of callers. Much of this code is about to get a major rework due to bug #92363, so I don't think it matters too much. In fact, I discovered this bug while working on the other bug. Le bon temps!

* mesa/meta: Use interpolateAtOffset for 16x MSAA copy blitNeil Roberts2015-11-051-2/+37
| | | | | | | | | | | | | | | | | | | | | | | | | Previously there was a problem in i965 where if 16x MSAA is used then some of the sample positions are exactly on the 0 x or y axis. When the MSAA copy blit shader interpolates the texture coordinates at these sample positions it was possible that it would jump to a neighboring texel due to rounding errors. It is likely that these positions would be used on 16x MSAA because that is where they are defined to be in D3D. To fix that this patch makes it use interpolateAtOffset in the blit shader whenever 16x MSAA is used and the GL_ARB_gpu_shader5 extension is available. This forces it to interpolate the texture coordinates at the pixel center to avoid these problematic positions. This fixes ext_framebuffer_multisample-unaligned-blit and ext_framebuffer_multisample-clip-and-scissor-blit with 16x MSAA on SKL+. v2: Use interpolateAtOffset instead of interpolateAtSample v3: Always try to enable GL_ARB_gpu_shader5 in the shader [Ian Romanick] Reviewed-by: Anuj Phogat <[email protected]>
* meta/blit: Always try to enable GL_ARB_sample_shadingNeil Roberts2015-11-051-14/+2
| | | | | | | | | | | Previously this extension was only enabled when blitting between two multisampled buffers. However I don't think it does any harm to just enable it all the time. The ‘enable’ option is used instead of ‘require’ so that the shader will still compile if the extension isn't available in the cases where it isn't used. This will make the next patch simpler because it wants to add another optional extension. Reviewed-by: Anuj Phogat <[email protected]>

* meta: Handle array textures in scaled MSAA blitsIan Romanick2015-09-301-15/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old code had some significant problems with respect to sampler2DArray textures. The biggest problem was that some of the code would use vec3 for the texture coordinate type, and other parts of the code would use vec2. The resulting shader would not even compile. Since there were not tests for this path, nobody noticed. The input to the fragment shader is always treated as a vec3. If the source data is only vec2, the vertex puller will supply 0 for the .z component. The texture coordinate passed to the fragment shader is always a vec2 that comes from the .xy part of the vertex shader input. The layer, taken from the .z of the vertex shader input is passed separately as a flat integer. If the generated fragment shader does not use the layer integer, the GLSL linker will eliminate all the dead code in the vertex shader. Fixes the new piglit tests "blit-scaled samples=2 with gl_texture_2d_multisample_array", etc. on i965. Note for stable maintainer: This patch may depend on 46037237, and that patch should be safe for stable.

* mesa: rework Driver.CopyImageSubData() and related codeBrian Paul2015-09-242-8/+97
| | | | | | | | | | | | | | | | | | | | | | | | Previously, core Mesa's _mesa_CopyImageSubData() created temporary textures to wrap renderbuffer sources/destinations. This caused a bit of a mess in the Mesa/gallium state tracker because we had to basically undo that wrapping. Instead, change ctx->Driver.CopyImageSubData() to take both gl_renderbuffer and gl_texture_image src/dst pointers (one being null, the other non-null) so the driver can handle renderbuffer vs. texture as needed. For the i965 driver, we basically moved the code that wrapped textures around renderbuffers from copyimage.c down into the met and driver code. The old code in copyimage.c also made some questionable calls to _mesa_BindTexture(), etc. which weren't undone at the end. v2 (Jason Ekstrand): Rework the intel bits v3 (Brian Paul): Update the temporary st_CopyImageSubData() function.

* meta: Use result of texture coordinate clamping operationIan Romanick2015-09-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously the result of the complicated clamp() expression just dropped on the floor: clamp does not modify any of its parameters. Looking at the surrounding code, I believe this is supposed to modify the value of tex_coord. This change (along with a change to avoid the use of brw_blorp_framebuffer) does not affect any existing piglit tests. I'm not sure what this clamp is trying to accomplish, so I'm not sure how to write a test to exercise this path. I also noticed another bug in this code. There is no way the array texture case could possibly work. This will generate code for the TEXEL_FETCH macro like: #define TEXEL_FETCH(coord) texelFetch(texSampler, ivec3(coord), sample_map[int(2 * fract(coord.x))]); Since the coord parameter of this macro is a vec2 at all invocations, no expansion of this macro will even compile.
