* gallium: add BIND flags for R/W buffers and imagesMarek Olšák2015-07-167-13/+19
| | | | | | | | | | | | | | | | | PIPE_CAPs and TGSI support will be added later. The TGSI support should be straightforward. We only need to split TGSI_FILE_RESOURCE into TGSI_FILE_IMAGE and TGSI_FILE_BUFFER, though duplicating all opcodes shouldn't be necessary. The idea is: * ARB_shader_image_load_store should use set_shader_images. * ARB_shader_storage_buffer_object should use set_shader_buffers(slots 0..M-1) if M shader storage buffers are supported. * ARB_shader_atomic_counters should use set_shader_buffers(slots M..N) if N-M+1 atomic counter buffers are supported. PIPE_CAPs can describe various constraints for early DX11 hardware. Reviewed-by: Ilia Mirkin <[email protected]>

* i965/gen9: Use custom MOCS entries set up by the kernel.Francisco Jerez2015-07-162-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of relying on hardware defaults the i915 kernel driver is going program custom MOCS tables system-wide on Gen9 hardware. The "WT" entry previously used for renderbuffers had a number of problems: It disabled caching on eLLC, it used a reserved L3 cacheability setting, and it used to override the PTE controls making renderbuffers always WT on LLC regardless of the kernel's setting. Instead use an entry from the new MOCS tables with parameters: TC=LLC/eLLC, LeCC=PTE, L3CC=WB. The "WB" entry previously used for anything other than renderbuffers has moved to a different index in the new MOCS tables but it should have the same caching semantics as the old entry. Even though the corresponding kernel change ("drm/i915: Added Programming of the MOCS") is in a way an ABI break it doesn't seem necessary to check that the kernel is recent enough because the change should only affect Gen9 which is still unreleased hardware. v2: Update MOCS values for the new Android-incompatible tables introduced in v7 of the kernel patch.

* glsl: avoid compiler's segfault when processing operators with void argumentsRenaud Gaubert2015-07-162-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is done by returning an rvalue of type void in the ast_function_expression::hir function instead of a void expression. This produces (in the case of the ternary) an hir with a call to the void returning function and an assignment of a void variable which will be optimized out (the assignment) during the optimization pass. This fix results in having a valid subexpression in the many different cases where the subexpressions are functions whose return values are void. Thus preventing to dereference NULL in the following cases: * binary operator * unary operators * ternary operator * comparison operators (except equal and nequal operator) Equal and nequal had to be handled as a special case because instead of segfaulting on a forbidden syntax it was now accepting expressions with a void return value on either (or both) side of the expression.

| | | | | | | | | | | | The formats chosen (both by texture format choser, fbo storage allocation) are different for big endian not just for rgba8 but also lower bit width formats (why I don't actually know). Even the function to test for renderable formats used different formats, however the actual colorbuffer setup did not. And the blitter did not take that into account neither.

| | | | | | | | | | | Blit submits lots of packets which are usually handled by state atoms, so these must be dirtied.

* r200: fix fbo rendering by disabling optimized texture format chooserRoland Scheidegger2015-07-161-1/+13
| | | | | | | | | | | | It is rather unfortunate that we don't know if a texture is going to be used as a rt later, and we lack the means to do something about a format chosen which we can't render to directly, so disable this and always chose renderable format for rgba8 textures. This addresses an issue raised on (old) bug, https://bugs.freedesktop.org/show_bug.cgi?id=51658 with gnome-shell, don't know if that's still applicable but it might fix other things as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | Previously OUT_BATCH was just a macro around an inline function which does brw->batch.map[brw->batch.used++] = dword; When making consecutive calls to intel_batchbuffer_emit_dword() the compiler isn't able to recognize that we're writing consecutive memory locations or that it doesn't need to write batch.used back to memory each time. We can avoid both of these problems by making a local pointer to the next location in the batch in BEGIN_BATCH().
