* st/mesa: implement blit-based ReadPixelsMarek Olšák2013-03-233-13/+189
| | | | | | | | | | | | | | | Initial version contributed by: Martin Andersson <[email protected]> This is only used if the memcpy path cannot be used and if no transfer ops are needed. It's pretty similar to our TexImage and GetTexImage implementations. The motivation behind this is to be able to use ReadPixels every frame and still have at least 20 fps (or 60 fps with a powerful GPU and CPU) instead of 0.5 fps.

* llvmpipe: add EXT_packed_float render target format supportRoland Scheidegger2013-03-224-2/+382
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* i965: Add a driconf option to disable flush throttling.Paul Berry2013-03-214-2/+15
| | | | | | | | | | | | | | | Normally when submitting the first batch buffer after a flush, we check whether the GPU has completed processing of the first batch buffer of the previous frame. If it hasn't, we wait for it to finish before submitting any more batches. This prevents GPU-heavy and CPU-light applications from racing too far ahead of the current frame, but at the expense of possibly lower frame rates. Sometimes when benchmarking we want to disable this mechanism. This patch adds the driconf option "disable_throttling" to disable the throttling mechanism.

* i965: Don't use texture swizzling to force alpha to 1.0 if unnecessary.Kenneth Graunke2013-03-201-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 33599433c7 began setting the texture swizzle mode to XYZ1 for RED, RG, and RGB textures in order to force alpha to 1.0 in case we actually stored the texture as RGBA. This had a unforseen performance implication: the shader precompile assumes that the texture swizzle mode will be XYZW for non-shadow sampler types. By setting it to XYZ1, this means every shader used with a RED, RG, or RGB texture has to be recompiled. This is a very common case. Unfortunately, there's no way to improve the precompile, since RGBA textures still need XYZW, and there's no way to know by looking at the shader source what texture formats might be used. However, we only need to smash alpha to 1.0 if the texture's memory format actually has alpha bits. If not, the sampler already returns 1.0 for us without any special swizzling. XRGB8888, for example, is a very common case where this occurs. This partially fixes a performance regression since commit 33599433c7. More work is required to fully fix it in all cases. This at least helps Warsow. NOTE: This is a candidate for the 9.1 branch. Reviewed-by: Carl Worth <[email protected]> Signed-off-by: Kenneth Graunke <[email protected]>
* i965: Don't print a fatal-looking message if intelCreateContext fails.Kenneth Graunke2013-03-201-1/+0
| | | | | | | | | | | | | | | | | | | | With the old context creation mechanism, an application asked the GL to give it a context. Failing to produce a context was a fatal error. Now, with GLX_ARB_create_context, the application can request a specific version. If it's higher than the maximum version we support, context creation will fail. But this is a normal error that applications recover from. In particular, the new glxinfo tries to create OpenGL 4.3, 4.2, 4.1, 4.0, 3.3, and 3.2 contexts before finally succeeding at creating a 3.1 context. This led to it printing the following message 6 times: "brwCreateContext: failed to init intel context" There's no need to alarm users (and developers) with such a message.

* i965/fs: Avoid unnecessary recompiles due to POS bit of proj_attrib_mask.Paul Berry2013-03-192-2/+12
| | | | | | | | | | | | | | | | | | | | | | Previous to this patch, when using fixed function fragment shading, bit VARYING_BIT_POS of brw_wm_prog_key::proj_attrib_mask was being set differently during precompiles and normal usage. During precompiles it was being set only if the fragment shader reads from window position (which it never does), so it was always being set to 0. During normal usage it was being set if the vertex shader writes to all 4 components of gl_Position (which it usually does), so it was usually being set to 1. As a result, we were almost always doing an extra recompile for the fixed function fragment shader. The recompile was totally unnecessary, though, because brw_wm_prog_key::proj_attrib_mask is only consulted for fs_visitor::emit_general_interpolation(), which isn't used for VARYING_SLOT_POS. This patch avoids the unnecessary recompile by always setting bit VARYING_BIT_POS of brw_wm_prog_key::proj_attrib_mask to 1. Reviewed-by: Kenneth Graunke <[email protected]>
* ff_fragment_shader: Don't do unnecessary (and dangerous) uniform setup.Paul Berry2013-03-191-16/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, right after calling _mesa_glsl_link_shader(), the fixed function fragment shader code made several calls with the ostensible purpose of setting up uniforms for the fragment shader it just created. These calls are unnecessary, since _mesa_glsl_link_shader() calls driver->LinkShader(), which takes care of calling these functions (or their equivalent). Also, they are dangerous to call after _mesa_glsl_link_shader() has returned, because on back-ends such as i965 which do precompilation, _mesa_glsl_link_shader() may have already cached pointers to the existing uniform structures; attempting to set up the uniforms again invalidates those cached pointers. It was only by sheer coincidence that this wasn't manifesting itself as a bug. It turns out that i965's precompile mechanism was always setting bit 0 of brw_wm_prog_key::proj_attrib_mask to 0 for fixed function fragment shaders, but during normal usage this bit usually gets set to 1. As a result, the precompiled shader (with its invalid uniform pointers) was not being used. I'm about to introduce some changes that cause bit 0 of proj_attrib_mask to be set consistently between precompilation and normal usage, so to avoid regressions I need to get rid of the dangerous duplicate uniform setup code first.

| | | | | | | | | | | | | | | | | | | | | | | | | Since apps typically begin rendering with a call to glClear(), it is likely that when brw_workaround_depthstencil_alignment() moves a miplevel to a temporary buffer, it can avoid doing a blit, since the contents of the miplevel are about to be erased.

(v2): And, we also can't just continue as nothing happened, since the mask update code would later check if we actually have a mask, so we need to remember that there was a return in main where we didn't exit (to illustrate this, a ret in a if clause would cause a mask update which is still ok as we're in a conditional, but after the endif the mask update code would drop the mask hence bringing execution back to pixels which should have their execution mask set to zero by the ret).
