* i965: Compute dFdy() correctly for FBOs.Paul Berry2012-06-226-9/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On i965, dFdx() and dFdy() are computed by taking advantage of the fact that each consecutive set of 4 pixels dispatched to the fragment shader always constitutes a contiguous 2x2 block of pixels in a fixed arrangement known as a "sub-span". So we calculate dFdx() by taking the difference between the values computed for the left and right halves of the sub-span, and we calculate dFdy() by taking the difference between the values computed for the top and bottom halves of the sub-span. However, there's a subtlety when FBOs are in use: since FBOs use a coordinate system where the origin is at the upper left, and window system framebuffers use a coordinate system where the origin is at the lower left, the computation of dFdy() needs to be negated for FBOs. This patch modifies the fragment shader back-ends to negate the value of dFdy() when an FBO is in use. It also modifies the code that populates the program key (brw_wm_populate_key() and brw_fs_precompile()) so that they always record in the program key whether we are rendering to an FBO or to a window system framebuffer; this ensures that the fragment shader will get recompiled when switching between FBO and non-FBO use. This will result in unnecessary recompiles of fragment shaders that don't use dFdy(). To fix that, we will need to adapt the GLSL and NV_fragment_program front-ends to record whether or not a given shader uses dFdy(). I plan to implement this in a future patch series; I've left FIXME comments in the code as a reminder. Fixes Piglit test "fbo-deriv". NOTE: This is a candidate for stable release branches.

* dricore: Turn it into a normal library.Eric Anholt2012-06-211-9/+9
| | | | | | | | | | | | Our intention is still that it's not abi stable, so make the package version number get included in the library name. Now you can parallel install dricore-using drivers from multiple mesa versions. We can put it into lib now that we're following library versioning rules (assuming that ABIs don't change within a single Mesa point release). LD_LIBRARY_PATH still doesn't work with a non-/, non-/usr prefix because libtool uses rpath instead of runpath for nonstandard prefixes.

| | | | | | | | | The weird versioning of the libGL where the package version was sort of expressed as a big integer is dropped. libtool didn't like the 0 prefix, and it didn't really make sense anyway -- if you interpret it as an integer version number, old Mesa 071200 was bigger than current Mesa 08100. Instead, just bump the minor version and drop the patchlevel.

* st/mesa: fix transform feedback of unsubscripted gl_ClipDistance arrayMarcin Slusarz2012-06-202-44/+6
| | | | | | | | | | | | | | | | | | | | | | | | | gl_ClipDistance needs special treatment in form of lowering pass which transforms gl_ClipDistance representation from float[] to vec4[]. There are 2 implementations - at glsl linker level (enabled by LowerClipDistance option) and at glsl_to_tgsi level (enabled unconditionally for gallium drivers). Second implementation is incomplete - it does not take into account transform feedback (see commit 642e5b413e0890b2070ba78fde42db381eaf02e5 "mesa: Fix transform feedback of unsubscripted gl_ClipDistance array" for details). There are 2 possible fixes: - adding transform feedback support into glsl_to_tgsi version - ripping gl_ClipDistance support from glsl_to_tgsi and enabling gl_ClipDistance lowering on glsl linker side This patch implements 2nd option. All it does is: - reverts most of the commit 59be691638200797583bce39a83f641d30d97492 "st/mesa: add support for gl_ClipDistance" - changes LowerClipDistance to true Fixes Piglit tests "EXT_transform_feedback/builtin-varyings gl_ClipDistance[{2,3,4,5,6,7,8}]-no-subscript" at least on nv50 and evergreen cards.
* i965/msaa: Only do multisample rasterization if GL_MULTISAMPLE enabled.Paul Berry2012-06-204-18/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | From the GL 3.0 spec (p.116): "Multisample rasterization is enabled or disabled by calling Enable or Disable with the symbolic constant MULTISAMPLE." Elsewhere in the spec, where multisample rasterization is described (sections 3.4.3, 3.5.4, and 3.6.6), the following text is consistently used: "If MULTISAMPLE is enabled, and the value of SAMPLE_BUFFERS is one, then..." So, in other words, disabling GL_MULTISAMPLE should prevent multisample rasterization from occurring, even if the draw framebuffer is multisampled. This patch implements that behaviour by setting the WM and SF stage's "multisample rasterization mode" to MSRAST_ON_PATTERN only when the draw framebuffer is multisampled *and* GL_MULTISAMPLE is enabled.

* i965/msaa: Disable unsupported formats.Paul Berry2012-06-201-0/+13
| | | | | | | | | | | | | | | | | | | | | | | Due to hardware limitations, MSAA is unsupported on Gen6 for formats containing >64 bits of data per pixel. From the Sandy Bridge PRM, vol4 part1, p72 ("Surface Format"): If Number of Multisamples is set to a value other than MULTISAMPLECOUNT_1, this field cannot be set to the following formats: - any format with greater than 64 bits per element - any compressed texture format (BC*) - any YCRCB* format Gen7 has a similar, but less stringent limitation: formats with >64 bits of data per pixel only support 4x MSAA.

* i965: Fix brw_swap_cmod() for LE/GE comparisons.Kenneth Graunke2012-06-181-4/+4
| | | | | | | | | | | | | | | | | | | | | The idea here is to rewrite comparisons like 2 >= x with x <= 2; we want to simply exchange arguments, not negate the condition. If equality was part of the original comparison, it should remain part of the swapped version. This is the true cause of bug #50298. It didn't manifest itself on Sandybridge because we embed the conditional modifier in the IF instruction rather than emitting a CMP. All other platforms use CMP. It also didn't manifest itself on the master branch because commit be5f27a84d ("glsl: Refine the loop instruction counting.") papered over the problem.

Fixes piglit tests "EXT_framebuffer_multisample/clip-and-scissor-blit" on i965/Gen6+. Also substantially speeds up the Humble Bundle V game "Psychonauts" on Gen6+ (without this patch, the game's depth buffer blits use the slow blit meta-op). Reviewed-by: Carl Worth <[email protected]>
