* direct-to-native-GL for GLX clients on Cygwin ("Windows-DRI")Jon Turney2016-09-1520-4/+2066
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Structurally, this is very similar to the existing Apple-DRI code, except I have chosen to implement this using the __GLXDRIdisplay, etc. vtables (as suggested originally in [1]), rather than a maze of ifdefs. This also means that LIBGL_ALWAYS_SOFTWARE and LIBGL_ALWAYS_INDIRECT work as expected. [1] https://lists.freedesktop.org/archives/mesa-dev/2010-May/000756.html This adds: * the Windows-DRI extension protocol headers and the windowsdriproto.pc file, for use in building the Windows-DRI extension for the X server * a Windows-DRI extension helper client library * a Windows-specific DRI implementation for GLX clients The server is queried for Windows-DRI extension support on the screen before using it (to detect the case where WGL is disabled or can't be activated). The server is queried for fbconfigID to pixelformatindex mapping, which is used to augment glx_config. The server is queried for a native handle for the drawable (which is of a different type for windows, pixmaps and pbuffers), which is used to augment __GLXDRIdrawable. Various GLX extensions are enabled depending on if the equivalent WGL extension is available.

* mesa: Expose RESET_NOTIFICATION_STRATEGY with KHR_robustness.Kenneth Graunke2016-09-152-3/+10
| | | | | | | | | | | | | | | This is supposed to be exposed with the GL_KHR_robustness extension, which we support on ES 2.0 and later. On desktop GL, it's also exposed by GL_ARB_robustness, which is supported by all drivers ("dummy_true"). so we also allow desktop GL.

* intel/blorp: Stop setting 3DSTATE_DRAWING_RECTANGLEJason Ekstrand2016-09-143-20/+5
| | | | | | | | | | | | The Vulkan driver sets 3DSTATE_DRAWING_RECTANGLE once to MAX_INT x MAX_INT at the GPU initialization time and never sets it again. The GL driver sets it every time the framebuffer changes. Originally, blorp set it to the size of the drawing area but meant we had to set it back in the Vulkan driver. Instead, we can easily just do that in the GL driver's blorp_exec implementation and not set it in blorp core.

* i965/vec4: Don't spill non-GRF-aligned register regions.Francisco Jerez2016-09-142-2/+5
| | | | | | | | | | | A better fix would be to do something along the lines of the FS back-end spilling code and emit a scratch read before any instruction that overwrites the register to spill partially due to a non-zero sub-register offset. In the meantime mark registers used with a non-zero sub-register offset as no-spill to prevent the spilling code from miscompiling the program. Reviewed-by: Iago Toral Quiroga <[email protected]>
* i965/vec4: Fix copy propagation for non-register-aligned regions.Francisco Jerez2016-09-141-3/+6
| | | | | | | | | | | | | | This prevents it from trying to propagate a copy through a register-misaligned region. MOV instructions with a misaligned destination shouldn't be treated as a direct GRF copy, because they only define the destination GRFs partially. Also fix the interference check implemented with is_channel_updated() to consider overlapping regions with different register offset to interfere, since the writemask check implemented in the function is only valid under the assumption that the source and destination regions are aligned component by component.

* i965/fs: Get rid of fs_inst::set_smear().Francisco Jerez2016-09-143-32/+15
| | | | | | | | | | | | | | | | | | | component() was generally a better alternative because of several issues set_smear() had: - It wouldn't take the original stride and offset of the register into account, which means that set_smear() on the result of e.g. another set_smear() call or an offset() call would give a bogus region as result. - It was an inherently destructive operation. See the 'nir_intrinsic_shader_clock' hunk below for how this could lead to subtle bugs in cases where set_smear() was called multiple times on the same register like 'r.set_smear(0), r.set_smear(1)' with the expectation that each call would return a separate value instead of a reference to the same subsequently mutated object.

The offset from the start of the copy destination register 'inst->dst' where the destination of the generating instruction 'scan_inst' would be written to (before compute-to-mrf runs) is just the offset of 'scan_inst->dst' relative to the source of the copy instruction (AKA rel_offset in the code below).
