* 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 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.

* glsl: Fix uniform buffer object counting.Eric Anholt2013-06-061-1/+9
| | | | | | | | | | | | | | | | | | | | We were counting uniforms located in UBOs against the default uniform block limit, while not doing any counting against the specific combined limit. Note that I couldn't quite find justification for the way I did this, but I think it's the only sensible thing: The spec talks about components, so each "float" in a std140 block would count as 1 component and a "vec4" would count as 4, though they occupy the same amount of space. Since GPU limits on uniform buffer loads are surely going to be about the size of the blocks, I just counted them that way. Fixes link failures in piglit arb_uniform_buffer_object/maxuniformblocksize when ported to geometry shaders on Paul's GS branch, since in that case the max block size is bigger than the default uniform block component limit.

| | | | | | | | | | | | | | | | Blorp and the hardware blitter can't be used to implement CopyTexSubImage when the image type is 1D_ARRAY, because of a coordinate system mismatch (the Y coordinate in the source image is supposed to be matched up to the Z coordinate in the destination texture).

| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 045612c (intel: Add an assert for glCopyTexSubImage() being called on MSAA buffers) added an assertion to intel_copy_texsubimage() to make sure that multisampling was not in use, based on the assumption that glCopyTexSubImage() can't legally be used with multisampling. However, there is one case where glCopyTexSubImage() can legally be used with multisampling: when the source buffer is a multisampled window system buffer. If the source and destination color formats don't match, the blorp path will fail, so intel_copy_texsubimage() will be called. In this case, we need intel_copy_texsubimage() to return false so that we fall back to meta to do the copy. (The multisampled source buffer won't cause a problem for the meta path, because it uses glReadPixels, which forces a multisample resolve). It's still safe to assert that the destination image is single-sampled, because it's not legal to call glCopyTexSubImage() on multisampled textures.

* intel: Add multisample scaled blitting in blorp engineAnuj Phogat2013-05-304-74/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | In traditional multisampled framebuffer rendering, color samples must be explicitly resolved via BlitFramebuffer before doing the scaled blitting of the framebuffer. So, scaled blitting of a multisample framebuffer takes two separate calls to BlitFramebuffer. This patch implements the functionality of doing multisampled scaled resolve using just one BlitFramebuffer call. Important changes involved in this patch are listed below: - Use float registers to scale and offset texture coordinates. - Change offset computation to consider float coordinates. - Round the scaled coordinates down to nearest integer. - Modify src texture coordinates clipping to account for scaling.. - Linear filter is not yet implemented in blorp. So, don't use blorp engine to do single sampled scaled blitting. V3: Fix nearest filtering issue in scaled blits.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Pre-Haswell hardware doesn't support an arbitrary restart index, and instead compares the index buffer value against 0xFF for byte-size buffers, 0xFFFF for short-size buffers, or 0xFFFFFFFF for unsigned integer buffers. OpenGL allows the restart index to be an arbitrary unsigned integer. When comparing against byte/short types, the index buffer value should be promoted to a full 32-bit integer before doing the comparison. The restart index is /not/ supposed to be masked to byte/short size. This means that with certain restart indexes, the comparison should always fail. For example, a restart index of 0xF000FFFF should never match any byte/short index buffer values due to the extra high bits. We must not enable hardware primitive restart in such a case. For now, fall back to software primitive restart as it's the simplest fix. In the future, we could detect restart indexes that will never match and skip both hardware and software primitive restart.
