* i965: Use BDW_MOCS_PTE for renderbuffers.Kenneth Graunke2014-10-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Write-back caching cannot be used for buffers being scanned out by the display engine; surfaces used for scan-out must be write-through or uncached. I originally chose WT for render targets because it works in all cases. However, we really want to use write-back caching where possible, as it is more efficient. Most renderbuffers are not used for scanout - off-screen FBOs certainly are fine, and non-pageflipped backbuffers should be fine as well. So in most cases WB will work. However, we don't know what will be used for scan-out, so we instead simply use the PTE value specified by the kernel, as it knows these things. This matches our MOCS choice on Haswell. Fixes performance regressions since commit ee4484be3dc827cf15bcf109f5 in a microbenchmark (spotted by Eero Tamminen). Improves performance in GLBenchmark 2.7/EgyptHD by 7.44362% +/- 0.496939% (n=55) on a Broadwell GT2. Improves performance in a bunch of other microbenchmarks by ~15% or so.

* i965: Add a BRW_MOCS_PTE #define.Kenneth Graunke2014-10-091-3/+7
| | | | | | | | | | | | | | Like BDW_MOCS_WB and BDW_MOCS_WT, this specifies that we want to use all three caches (L3, LLC, and eLLC where available), but leaves the LLC caching mode up to the kernel's page table entry. This allows the kernel to pick WB/WT/UC based on whether it's using a buffer for scanout.

* mesa: fix spurious wglGetProcAddress / GL_INVALID_OPERATION errorBrian Paul2014-10-031-1/+35
| | | | | | | | | | | | | | | | | | On Windows, the Piglit primitive-restart test was failing a glGetError()==0 assertion when it was run w/out any command line arguments. Piglit's all.py script only runs primitive-restart with arguments so this case isn't normally hit during a full piglit run. The basic problem is Microsoft's opengl32.dll calls glFlush from wglGetProcAddress() and Piglit uses wglGetProcAddress() to resolve glPrimitiveRestartNV() which is called inside glBegin/End. See comments in the code for more info. Plus, improve the comments for _mesa_alloc_dispatch_table(). Cc: <[email protected]> Acked-by: Sinclair Yeh <[email protected]>

* st/mesa: Fix paths used in Android buildsTomasz Figa2014-10-033-0/+6
| | | | | | | | | | | | | | | | | | With current makefiles the build fails because source and build paths are generated incorrectly. With Android build system the top_srcdir and top_builddir variables are undefined and all paths are relative to where Android.mk is located. This ends up with path likes external/mesa/src/mesa/src/mesa/ for both source and build paths, which are obviously wrong. This patch fixes this by overriding resulting SRCDIR and BUILDDIR variables with empty string, so that paths end up being relative to Android.mk file again.

* meta: Implement ext_framebuffer_multisample_blit_scaled extensionAnuj Phogat2014-10-012-13/+199
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extension enables doing a multisample buffer resolve and buffer scaling using a single glBlitFrameBuffer() call. Currently, we have this extension implemented in BLORP which is only used by SNB and IVB. This patch implements the extension in meta path which makes it available to Broadwell. Implementation features: - Supports scaled resolves of 2X, 4X and 8X multisample buffers. - Avoids unnecessary shader compilations by storing the pre compiled shaders for each supported sample count. - Uses bilinear filtering for both GL_SCALED_RESOLVE_FASTEST_EXT and GL_SCALED_RESOLVE_NICEST_EXT filter options. This is an allowed behavior in the extension's spec. - I tried doing bicubic filtering for GL_SCALED_RESOLVE_NICEST_EXT filter. It made the edges in the image look little smoother but the image gets blurred causing no overall quality improvement. For now I have dropped the idea of doing different filtering for nicest filter. V2: - Minor changes to simplify the fragment shader. - Refactor the code to move i965 specific sample_map computation out of Meta. We now use ctx->Const.SampleMap{2,4,8}x variables initialized by the driver. - Use a simple msaa resolve shader for scaled resolves with scaling factor = 1.0. V3: - Make changes to create a string out of ctx->Const.SampleMap{2,4,8}x variables and use it in fragment shader. V4: - Make changes to use uint8_t type ctx->Const.SampleMap{2,4,8}x variables.
