* mesa: Set the correct error in _mesa_BeginConditionalRenderIan Romanick2014-01-101-11/+30
| | | | | | | | | | | | Piglit was recently changed to expect the correct error code (piglit commit 271b998), so it started failing on Mesa. This corrects that failing and adds some spec quotations to justify the errrors set. The code was rearranged a little bit to match the order listed in the spec.

* i965: Fix clears of layered framebuffers with mismatched layer counts.Paul Berry2014-01-108-30/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, Mesa enforced the following rule (from ARB_geometry_shader4's list of criteria for framebuffer completeness): * If any framebuffer attachment is layered, all attachments must have the same layer count. For three-dimensional textures, the layer count is the depth of the attached volume. For cube map textures, the layer count is always six. For one- and two-dimensional array textures, the layer count is simply the number of layers in the array texture. { FRAMEBUFFER_INCOMPLETE_LAYER_COUNT_ARB } However, when ARB_geometry_shader4 was adopted into GL 3.2, this rule was dropped; GL 3.2 permits different attachments to have different layer counts. This patch brings Mesa in line with GL 3.2. In order to ensure that layered clears properly clear all layers, we now have to keep track of the maximum number of layers in a layered framebuffer. Fixes the following piglit tests in spec/!OpenGL 3.2/layered-rendering: - clear-color-all-types 1d_array mipmapped - clear-color-all-types 1d_array single_level - clear-color-mismatched-layer-count - framebuffer-layer-count-mismatch Reviewed-by: Anuj Phogat <[email protected]> Reviewed-by: Chris Forbes <[email protected]>

| | | | | | | | | | | | | | From section 4.4.4 (Framebuffer Completeness) of the GL 3.2 spec: If any framebuffer attachment is layered, all populated attachments must be layered. Additionally, all populated color attachments must be from textures of the same target. We weren't checking that the attachments were from textures of the same target.

* i965/gen6/blorp: Remove redundant HiZ workaroundChad Versace2014-01-091-14/+0
| | | | | | | | | | | | | | | Commit 1a92881 added extra flushes to fix a HiZ hang in WebGL Google Maps. With the extra flushes emitted by the previous two patches, the flushes added by 1a92881 are redundant. Tested with the same criteria as in 1a92881: by zooming in and out continuously for 2 hours on Sandybridge Chrome OS (codename Stumpy) without a hang.

* i965/gen6/blorp: Set need_workaround_flush at top of blorpChad Versace2014-01-091-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unconditionally set brw->need_workaround_flush at the top of gen6 blorp state emission. The art of emitting workaround flushes on Sandybridge is mysterious and not fully understood. Ken and I believe that intel_emit_post_sync_nonzero_flush() may be required when switching from regular drawing to blorp. This is an extra safety measure to prevent undiscovered difficult-to-diagnose gpu hangs. I verified that on ChromeOS, pre-patch, need_workaround_flush was not set at the top of blorp, as Paul expected. To verify, I inserted the following debug code at the top of gen6_blorp_exec(), restarted the ui, and inspected the logs in /var/log/ui. The abort gets triggered so early that the browser never appears on the display. static void gen6_blorp_exec(...) { if (!brw->need_workaround_flush) { fprintf(stderr, "chadv: %s:%d\n", __FILE__, __LINE__); abort(); } ... } CC: Kenneth Graunke <[email protected]> CC: Stéphane Marchesin <[email protected]> Reviewed-by: Paul Berry <[email protected]> Signed-off-by: Chad Versace <[email protected]>
* i965/gen6/blorp: Set need_workaround_flush immediately after primitiveChad Versace2014-01-092-1/+3
| | | | | | | | | | | | | | | | | | | | This patch makes the workaround code in gen6 blorp follow the pattern established in the regular draw path. It shouldn't result in any behavioral change. On gen6, there are two places where we emit 3D_CMD_PRIM: brw_emit_prim() and gen6_blorp_emit_primitive(). brw_emit_prim() sets need_workaround_flush immediately after emitting the primitive, but blorp does not. Blorp sets need_workaround_flush at the bottom of brw_blorp_exec(). This patch moves the need_workaround_flush from brw_blorp_exec() to gen6_blorp_emit_primitive(). There is no need to set need_workaround_flush in gen7_blorp_emit_primitive() because the workaround applies only to gen6.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add for now some simple/basic query support (ie. things not actually requiring the GPU). Might change around a bit when I actually add GPU queries, but for now this enables some useful performance info in the GALLIUM_HUD. For example: GALLIUM_HUD=fps+batches+batches-sysmem+batches-gmem+restores,draw-calls The driver specific specific queries are: + draw-calls + batches - number of batches per second, sum of batches-sysmem plus batches-gmem + batches-gmem - render a set of tiles in GMEM, for each tile (optionally) system mem -> gmem (restore), plus N draws, plus gmem -> system mem (resolve) per second + batches-sysmem - N draws to system memory (GMEM bypass) per second + restores - number of GMEM batches that required restore per second Ideally for GMEM rendering, you want batches-gmem to equal fps. If the app is doing something that triggers multiple passes (ie. requires extra round trip gmem <-> system memory) then the # of batches per second will go up relative to fps.

* freedreno/a3xx: support for hw binning passRob Clark2014-01-0816-159/+707
| | | | | | | | | | | | | | | | | | | | | | | The binning pass sorts vertices into which bins/tiles they apply to. The visibility information generated during the binning pass can be used to speed up the rendering pass by filtering out vertices which do not apply to the current tile. See: https://github.com/freedreno/freedreno/wiki/Adreno-tiling#optimized-approach This brings a significant fps boost. A rough assortment of tests (supertuxkart, etracer, tremulous, glmark2 'build' test, etc) seems to yield a ~35-45% fps improvement. For now, to be conservative, the binning pass is not enabled yet by default. To enable it use: FD_MESA_DEBUG=binning So far I haven't found anything that breaks with binning enabled, but I'd like a bit more testing before I enable it as default.

| | | | | | | | | | | | | | | | | | | | | This reduces confusion since gl_shader::Type is sometimes GL_SHADER_PROGRAM_MESA but is more frequently GL_SHADER_{VERTEX,GEOMETRY,FRAGMENT}. It also has the advantage that when switching on gl_shader::Stage, the compiler will alert if one of the possible enum types is unhandled. Finally, many functions in src/glsl (especially those dealing with linking) already use gl_shader_stage to represent pipeline stages; using gl_shader::Stage in those functions avoids the need for a conversion.
