* gallium: fix type of flags in pipe_context::flush()Chia-I Wu2013-05-041-1/+1
| | | | | | | | | | | | | | | | It should be unsigned, not enum pipe_flush_flags. Fixed a build error: src/gallium/state_trackers/egl/android/native_android.cpp:426:29: error: invalid conversion from 'int' to 'pipe_flush_flags' [-fpermissive] v2: replace all occurrences of enum pipe_flush_flags by unsigned Signed-off-by: Chia-I Wu <[email protected]> Reviewed-by: Marek Olšák <[email protected]> [olv: document the parameter now that the type is unsigned]
* llvmpipe: get rid of depth swizzling.Roland Scheidegger2013-05-037-273/+414
| | | | | | | | | | | | | | | Eliminating this we no longer need to copy between linear and swizzled layout. This is probably not quite ideal since it's a bit more work for now, could do some optimizations by moving depth testing outside the fragment shader loop (but tricky for early depth test as we don't have neither the mask nor the interpolated z in the right order handy). The large amount of tile/untile code is no longer needed will be deleted in next commit. No piglit regressions. v2: change a forgotten LAYOUT_NONE to LAYOUT_LINEAR. v3: fix (bogus) uninitialized variable warnings, add comments, fix a bad type Reviewed-by: Jose Fonseca <[email protected]>

* st/mesa: optionally apply texture swizzle to border color v2Christoph Bumiller2013-04-181-0/+2
| | | | | | | | | | | | This is the only sane solution for nv50 and nvc0 (really, trust me), but since on other hardware the border colour is tightly coupled with texture state they'd have to undo the swizzle, so I've added a cap. The dependency of update_sampler on the texture updates was introduced to avoid doing the apply_depthmode to the swizzle twice. v2: Moved swizzling helper to u_format.c, extended the CAP to provide more accurate information.

| | | | | | | | | | | | | This is a basic implementation of the pipeline statistics in the draw module. The interface is similar to the stream output statistics and also requires that the callers explicitly enable it. Included is the implementation of the interface in llvmpipe and softpipe.

* draw/llvmpipe: allow independent so attachments to the vsZack Rusin2013-04-032-9/+27
| | | | | | | | | | | | | | When geometry shaders are present, one needs to be able to create an empty geometry shader with stream output that needs to be resolved later and attached to the currently bound vertex shader. Lets add support for it to llvmpipe and draw. draw allows attaching independent stream output info to any vertex shader and llvmpipe resolves at draw time which vertex shader the given empty geometry shader should be linked to.

* llvmpipe: use triangle subdivision to avoid fixed-point overflow issuesBrian Paul2013-04-013-0/+186
| | | | | | | | | | | | If we're drawing to a surface that's 2048 x 2048 pixels or larger there's danger of fixed-point overflow in the triangle rasterization code. That leads to various rendering glitches. Rather than implement some intricate changes to the rasterization code, simply subdivide triangles into smaller subtriangles to avoid the issue. Only do this when the drawing surface is larger than 2048 by 2048. Reviewed-by: José Fonseca <[email protected]>

* llvmpipe: add EXT_packed_float render target format supportRoland Scheidegger2013-03-222-2/+130
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New conversion code to handle conversion from/to r11g11b10 AoS to/from SoA floats, and also add code for conversion from rgb9e5 AoS to float SoA (which works pretty much the same as r11g11b10 except for the packing). (This code should also be used for texture sampling instead of relying on u_format conversion but it's not yet, so rgb9e5 is unused.) Unfortunately a crazy amount of hacks is necessary to get the conversion code running in llvmpipe's generate_unswizzled_blend, which isn't well suited for formats where the storage representation has nothing to do with what's needed for blending (moreover, the conversion will convert from packed AoS values, which is the storage format, to float SoA values, because this is much more natural for the conversion, and likewise from SoA values to packed AoS values - but the "blend" (which includes trivial things like partial mask) works on AoS values, so incoming fs values will go SoA->AoS, values from destination will go packed AoS->SoA->AoS, then do blend, then AoS->SoA->packed AoS which probably isn't the most efficient way though the shuffles are probably bearable). Passes piglit fbo-blending-formats (with GL_EXT_packed_float parameter), still need to verify Inf/NaNs (where most of the complexity in the conversion comes from actually). v2: drop the (very bogus) rgb9e5 part, and do component extraction in the helper code for r11g11b10 to float conversion, making the code slightly more compact (suggested by Jose), now that there are no other callers left this works quite well. (Could do the same for the opposite way but it's less than ideal there, final part of packing needs to be done in caller anyway and there'd be another conditional.) v3: minor style and comment fixes. Also fix a potential issue with negative zero being potentially returned by max(src, zero) as we don't have well-defined min/max behavior (fortunately no additonal cost).

The new PIPE_CAP_TGSI_TEXCOORD decides whether these varyings should be hidden behind the GENERIC semantic or not. With this patch only nvc0 and nv30 will request that they be used. v2: introduce a CAP so other drivers don't have to bother with the new semantic v3: adapt to introduction gl_varying_slot enum

| | | | | | | | | | | | | | | | | | | | We advertise a max texture/surfaces size of 8K x 8K but the old values for these limits didn't actually allow us to handle that surface size. For 8K x 8K we'll have 16384 bins. Each bin needs at least one cmd_block object which was 2192 bytes in size. Since 16384 * 2192 exceeded LP_SCENE_MAX_SIZE we'd silently fail in lp_scene_new_data_block() and not draw the complete scene. By reducing CMD_BLOCK_MAX to 29 we get nice 512-byte cmd_blocks. And by increasing LP_SCENE_MAX_SIZE to 9 MB we can allocate enough command blocks for 8K x 8K, plus a few regular data blocks. Fixes the (improved) piglit fbo-maxsize test.

* llvmpipe: support GL_ARB_texture_buffer_object/GL_ARB_texture_buffer_rangeRoland Scheidegger2013-02-256-103/+177
| | | | | | | | | | | | | | | | | | | | This also fixes not honoring first/last_layer view parameters for array textures, plus not honoring last_level view parameter for all textures (neither is really used by OpenGL). This mostly passes piglit arb_texture_buffer_object tests (it needs, however, glsl 140 version override, plus GL 3.1 override, the latter only because mesa does not allow ARB_tbo in non-core contexts). Most arb_texture_buffer_object tests pass, with the exception of arb_texture_buffer_object-formats. With "arb" parameter it passes most weirdo formats before it segfaults in the state tracker, this looks to be some issue with using legacy formats in core context (fails the same in softpipe). With "core" parameter it passes with "fs", however fails with "vs" (for most formats). This will be fixed later (debugging shows we're completely missing the shader recompile depending on format). v2: based on Jose's feedback, fix comments, variable/function names.
