* linker: Calculate used samplers and shadow samplers in the linkerIan Romanick2012-01-113-38/+20
| | | | | | | | | | | | It used to be done in ir_to_mesa, and that was kind of a bad place. I didn't change st_glsl_to_tgsi because there is some strange stuff happening in the code that generates glDrawPixels shaders. It looked like this would break horribly if I touched anything.

* mesa: Validate sampler settings using uniform storageIan Romanick2012-01-113-62/+48
| | | | | | | | | | | | | Rather than looking at the settings in individual assembly programs, look at the settings in the top-level uniform values. The old code was flawed because examining each shader stage in isolation could allow inconsitent usage across stages (e.g., bind unit 0 to a sampler2D in the vertex shader and sampler1DShadow in the fragment shader).

* mesa: Track fixed-function fragment shader as a shaderIan Romanick2012-01-117-5/+50
| | | | | | | | | | | | Previously the fixed-function fragment shader was tracked as a gl_program. This means that it shows up in the driver as a Mesa IR program instead of as a GLSL IR program. If a driver doesn't generate Mesa IR from the GLSL IR, that program is empty. If the program is empty there is either no rendering or a GPU hang.

* mesa: Use uniform interfaces in fixed-function fragment shader codeIan Romanick2012-01-111-5/+24
| | | | | | | | | | | Poking directly at the backing resources works only by luck. Core Mesa code should only know about the gl_uniform_storage structure. Soon other code that looks at samplers will use the gl_uniform_storage structures instead of the data in the gl_program.

* i965: Don't reallocate push constant URB space on new VS programs.Kenneth Graunke2012-01-113-10/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The gen7_urb atom depends on CACHE_NEW_VS_PROG and CACHE_NEW_GS_PROG, causing gen7_upload_urb() to be called when switching to a new VS program. In addition to partitioning the URB space between the VS and GS, gen7_upload_urb() also allocated space for VS and PS push constants. Unfortunately, this meant that whenever CACHE_NEW_VS was flagged, we'd reallocate the space for the PS push constants. According to the BSpec, after sending 3DSTATE_PUSH_CONSTANT_ALLOC_PS, we must reprogram 3DSTATE_CONSTANT_PS prior to the next 3DPRIMITIVE. Since our URB allocation for push constants is entirely static, it makes sense to split it out into its own atom that only subscribes to BRW_NEW_CONTEXT. This avoids reallocating the space and trashing constants. Fixes a rendering artifact in Extreme Tuxracer, where instead of a snow trail, you'd get a bright red streak (affectionately known as the "bloody penguin bug"). This also explains why adding VS-related dirty bits to gen7_ps_state made the problem disappear: it made 3DSTATE_CONSTANT_PS be emitted after every 3DSTATE_PUSH_CONSTANT_ALLOC_PS packet. NOTE: This is a candidate for the 7.11 branch.

| | | | | | | | | | | | | | We were naively emitting each component at a time, even if we were emitting the same value to multiple channels. Improves on a codegen regression from the old VS to the new VS on some unigine shaders (because we emit constant vecs/matrices as immediates instead of loading them as push constants, so we had over 4x the instructions for using them). shader-db results: Total instructions: 58594 -> 58540 11/870 programs affected (1.3%) 765 -> 711 instructions in affected programs (7.1% reduction)

* mesa: Fix transform feedback of unsubscripted gl_ClipDistance array.Paul Berry2012-01-111-0/+2
| | | | | | | | | | | | | | | | | | | | | On drivers that set gl_shader_compiler_options::LowerClipDistance (for example i965), we need to handle transform feedback of gl_ClipDistance specially, to account for the fact that the hardware represents it as an array of vec4's rather than an array of floats. The previous way this was accounted for (translating the request for gl_ClipDistance[n] to a request for a component of gl_ClipDistanceMESA[n/4]) doesn't work when performing transform feedback on the whole unsubscripted array, because we need to keep track of the size of the gl_ClipDistance array prior to the lowering pass. So I replaced it with a boolean is_clip_distance_mesa, which switches on the special logic that is needed to handle the lowered version of gl_ClipDistance. Fixes Piglit tests "EXT_transform_feedback/builtin-varyings gl_ClipDistance[{1,2,3,5,6,7}]-no-subscript". Reviewed-by: Eric Anholt <[email protected]>

| | | | | | | | | | | | | | | | | It is unwise to use a stencil region's size to determine its renderbuffer's size, because at region creation we fudge the width and height to accomodate interleaved rows. (See the comment for MESA_FORMAT_S8 in intel_miptree_create()). Most users of stencil_region->{width,height} should be converted to use stencil_rb->{Width,Height}. We have already done the replacement in several locations. This patch continues the replacement in {brw,gen7}_emit_depthbuffer(). To make those functions look consistent, I've also done the equivalent replacement for the depth buffer.
