* gallivm: work around slow code generated for interleaving 128bit vectorsRoland Scheidegger2013-06-081-0/+22
| | | | | | | | | | | | | | | We use 128bit vector interleave for untwiddling in the blend code (with 256bit vectors). llvm generates terrible code for this for some reason, so instead of generating a shuffle for 2 128bit vectors use a extract/insert shuffle instead (it only seems to matter we're not using 128bit wide vectors for the shuffle). This decreases instruction count of the blend code generated for a rgba8 render target without blending from 169 to 113 with llvm 3.1 and from 136 to 114 in llvm 3.2/3.3, and I got a ~8% (llvm 3.1) and ~5% (3.2/3.3) performance improvement in gears. (The generated code is still not terribly good as we could actually avoid the interleaving completely but llvm can't know this.) Reviewed-by: Jose Fonseca <[email protected]>
* scons: Fix implicit python dependency discovery on Windows.José Fonseca2013-06-081-1/+2
| | | | | | | | Probably due to CRLF endings, the discovery of python import statements was not working on Windows builds, causing incremental builds to often fail unless one wiped out the build directory. NOTE: This is a candidate for stable branches.
* st/xlib: Flush the front buffer before doing CopySubBufferStéphane Marchesin2013-06-071-0/+4
| | | | | | | | | We flush pending rendering before running CopySubBuffer, which ensures that the right bits get to the screen. NOTE: This is a candidate for stable release branches. Reviewed-by: Brian Paul <[email protected]>

* mesa: Report core FBO incompleteness cases through GL_ARB_debug_output.Eric Anholt2013-06-071-18/+25
| | | | | | | | | | | | | Just like we produce from inside the Intel driver, this can help provide information quickly about FBO incompatibility problems (particularly when using apitrace replay). Currently, in driver-marked incompleteness cases, you'll get both the driver message and the core message on Intel. Until the other drivers are fixed to produce output, I think this is better than not putting in a message for driver-marked incomplete. Reviewed-by: Brian Paul <[email protected]>
* intel: flush fake front buffer if server is about to destroy it.Paul Berry2013-06-071-0/+9

* intel: flush fake front buffer more robustly.Paul Berry2013-06-071-11/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | When a fake front buffer is in use, if we request the front buffer (using screen->dri2.loader->getBuffersWithFormat()), the X server copies the real front buffer to the fake front buffer and returns the fake front buffer. We sometimes make redundant requests for the front buffer (due to using a single counter to track invalidates for both the front and back buffers), so there's a danger of pending front buffer rendering getting overwritten when the redundant front buffer request occurs. Previous to this patch, intel_update_renderbuffers() worked around that problem by sometimes doing intel_flush() and intel_flush_front() before calling intel_query_dri2_buffers(). But it only did the workaround when the front buffer was bound for drawing; it didn't do it when the front buffer was bound for reading. This patch moves the workaround code to intel_query_dri2_buffers(), so that it happens in exactly the circumstances where it is needed. This should fix some of the sporadic failures in Piglit tests fbo-sys-blit and fbo-sys-sub-blit. Reviewed-by: Chad Versace <[email protected]> Reviewed-by: Anuj Phogat <[email protected]>
* intel: make intel_flush_front safe to call during initial MakeCurrentPaul Berry2013-06-071-1/+1
| | | | | | | | | | | | | | The patch that follows will fix a bug that prevents intel_flush_front() from being called often enough. In doing so, it will create a situation where intel_flush_front() is called during the initial call to glXMakeCurrent(). In this circumstance, ctx->DrawBuffer hasn't been initialized yet and is NULL. Fortunately, intel->front_buffer_dirty is false, so intel_flush_front() doesn't actually need to do anything. To avoid a segfault, swap the order of terms in intel_flush_front()'s if statement.
