* mesa/texformat: add integer fallbacks to other formatsDave Airlie2011-10-081-73/+131
| | | | | | | | | This fixes up the integer format choosing to pick the closest mesa format then the most likely fallback. (the formatting in this file needs cleaning in another patch). Signed-off-by: Dave Airlie <[email protected]>
* mesa: add packing for int/uintDave Airlie2011-10-082-0/+68
| | | | | | | This just adds a simple packing for GL_UNSIGNED_INT/GL_INT destination formats. This is enough for at least the gallium drivers to pack both unsigned and signed types for read pixels. Signed-off-by: Dave Airlie <[email protected]>
* i965: Fix inconsistent indentation in brw_eu_emit.c.Kenneth Graunke2011-10-071-197/+197
| | | | | | | | | | | | | | Most of these functions used three spaces for the first level of indentation, but four spaces for the next level. One used tabs and then three spaces. Some used 3/4 in a then block but 3/3 in the else block. Normally I try to avoid field days like this, but since the functions were so inconsistent, even internally, it was making it difficult to edit without introducing spurious whitespace changes. So, just get it over with. git diff -b shows 0 lines changed. Signed-off-by: Kenneth Graunke <[email protected]>

I've removed the dead format checks completely rather than replace them with more appropriate checks.

* mesa: fix image unpacking when storing compressed texturesBrian Paul2011-10-072-6/+19
| | | | | | | | | | | | | | This fixes failures found with the new piglit texsubimage test. Two things were broken: 1. The dxt code doesn't handle sources images where width != row stride. Check for that and take the _mesa_make_temp_ubyte_image() path to get an image where width = rowstride. 2. If we don't take the _mesa_make_temp_ubyte_image() path we need to take the source image unpacking parameters into account in order to get the proper starting memory address of the source texels. Note: This is a candidate for the 7.11 branch.
* i965 Gen6+: De-compact clip planes.Paul Berry2011-10-067-68/+56
| | | | | | | | | | | | | | | | | | | Previously, if the user enabled a non-consecutive set of clip planes (e.g. 0, 1, and 3), the driver would compact them down to a consecutive set starting at 0. This optimization was of dubious value, and complicated the implementation of gl_ClipDistance. This patch changes the driver so that with Gen6 and later chipsets, we no longer compact the clip planes. However, we still discard any clip planes beyond the highest number that is in use, so performance should not be affected for applications that use clip planes consecutively from 0. With chipsets previous to Gen6, we still compact the clip planes, since the pre-Gen6 clipper thread relies on this behavior.

| | | | | | | | | | The only remaining uses of brw_vs_prog_key::nr_userclip only occurred when using clip planes (as opposed to gl_ClipDistance). This patch renames the value to nr_userclip_planes and sets it to zero when gl_ClipDistance is in use. This avoids unnecessary VS recompiles.

| | | | | | | | | | | | | Previously, brw_compute_vue_map required an argument indicating the number of clip planes in use, but all it did with it was check if it was nonzero. This patch changes brw_compute_vue_map to take a boolean instead. This allows us to avoid some unnecessary recompilation of the Gen4/5 GS and SF threads.

* i965: Move ClipPlanesEnabled state to VS cache key.Paul Berry2011-10-063-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | Previous to this patch, setup_uniform_clipplane_values() was setting up clip plane uniforms based on ctx->Transform.ClipPlanesEnabled, a piece of state not stored in the vertex shader cache key. As a result, a change to this piece of state might not trigger a necessary vertex shader recompile. The patch adds a field to the vertex shader cache key, userclip_planes_enabled, to store the current value of ctx->Transform.ClipPlanesEnabled. Also, it changes setup_uniform_clipplane_values() to read from this new field, so that it's manifestly clear that the vertex shader isn't depending on state not stored in the cache key. Note: when the vertex shader uses gl_ClipDistance, the VS backend doesn't need to know which clip planes are in use, so we leave the field as zero in that case to avoid unnecessary recompiles.

* i965: Rearrange VS cache key struct.Paul Berry2011-10-061-1/+11
| | | | | | | | | | | No functional change. This patch rearranges the struct brw_vs_prog_key so that the two fields related to clipping are together, and documents those fields. This should make the patches that follow easier to comprehend, since they add additional clipping-related fields to this structure.

* mesa: Create _mesa_bitcount_64() to replace i965's brw_count_bits()Paul Berry2011-10-0613-21/+30
| | | | | | | | | | | | | | | | The i965 driver already had a function to count bits in a 64-bit uint (brw_count_bits()), but it was buggy (it only counted the bottom 32 bits) and it was clumsy (it had a strange and broken fallback for non-GCC-like compilers, which fortunately was never used). Since Mesa already has a _mesa_bitcount() function, it seems better to just create a _mesa_bitcount_64() function rather than special-case this in the i965 driver. This patch creates the new _mesa_bitcount_64() function and rewrites all of the old brw_count_bits() calls to refer to it.

* i965 Gen6: Implement gl_ClipVertex.Paul Berry2011-10-056-10/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements proper support for gl_ClipVertex by causing the new VS backend to populate the clip distance VUE slots using VERT_RESULT_CLIP_VERTEX when appropriate, and by using the untransformed clip planes in ctx->Transform.EyeUserPlane rather than the transformed clip planes in ctx->Transform._ClipUserPlane when a GLSL-based vertex shader is in use. When not using a GLSL-based vertex shader, we use ctx->Transform._ClipUserPlane (which is what we used prior to this patch). This ensures that clipping is still performed correctly for fixed function and ARB vertex programs. A new function, brw_select_clip_planes() is used to determine whether to use _ClipUserPlane or EyeUserPlane, so that the logic for making this decision is shared between the new and old vertex shaders. Fixes the following Piglit tests on i965 Gen6: - vs-clip-vertex-const-accept - vs-clip-vertex-const-reject - vs-clip-vertex-different-from-position - vs-clip-vertex-equal-to-position - vs-clip-vertex-homogeneity - vs-clip-based-on-position - vs-clip-based-on-position-homogeneity - clip-plane-transformation clipvert_pos - clip-plane-transformation pos_clipvert - clip-plane-transformation pos Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Chad Versace <[email protected]>
* mesa: Add a gl_vert_result for gl_ClipVertex.Paul Berry2011-10-051-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch, clip planes didn't work properly in Mesa when using vertex shaders, because Mesa assigned both gl_ClipVertex and gl_Position to the same gl_vert_result (VERT_RESULT_HPOS). As a result, backends couldn't distinguish between the two variables, so any shader that wrote different values to them would fail to work properly. This patch paves the way for proper support of gl_ClipVertex by creating a new enumerated value in gl_vert_result for it (VERT_RESULT_CLIP_VERTEX). After this patch, a back-end may add support for gl_ClipVertex using the following algorithm: - If using a user-supplied GLSL vertex shader: - If the bit corresponding to VERT_RESULT_CLIP_VERTEX is set in gl_program::OutputsWritten: - Clip using the vertex shader output VERT_RESULT_CLIP_VERTEX and the clip planes defined in gl_context::Transform.EyeUserPlane. - Else: - Clip using the vertex shader output VERT_RESULT_HPOS and the clip planes defined in gl_context::Transform.EyeUserPlane. - Else (either using fixed function or an ARB vertex program): - Clip using the vertex shader output VERT_RESULT_HPOS and the clip planes defined in gl_context::Transform._ClipUserPlane (*) where (*) represents the normal Mesa behavior before this patch. An example of implementing the above algorithm can be found in the patch that follows this one, which implements gl_ClipVertex in i965 Gen6. Reviewed-by: Kenneth Graunke <[email protected]>
