* mesa: change MAX_PROGRAM_ADDRESS_REGS to 1, clamp to it in state trackerBrian Paul2013-06-042-2/+3
| | | | | | | | | | | | | We've never properly supported more than one address register. There isn't even a field in prog_src_register or prog_dst_register to indicate which address register to use if RelAddr!=0. In the state tracker, clamp MaxAddressRegs against MAX_PROGRAM_ADDRESS_REGS since many gallium drivers do support more.

* intel: Don't try to blorp or blit CopyTexSubImage(1D_ARRAY).Paul Berry2013-06-042-0/+7
| | | | | | | | | | | | | | | | 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). The hardware blitter path (intel_copy_texsubimage) contained a perf debug warning for this case, but it failed to actually fall back. The blorp path didn't even check. Fixes piglit test "copyteximage 1D_ARRAY". Reviewed-by: Eric Anholt <[email protected]>
* i965/gen6+: Fix multisample assertions in CopyTexSubImage hw blitter path.Paul Berry2013-06-041-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. Fixes some failures with piglit tests "copyteximage {1D,2D,CUBE,RECT,2D_ARRAY}" (with "samples=..." argument). Reviewed-by: Eric Anholt <[email protected]>

* 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.

The hardware appears to compare against the full 32-bit value some of the time, causing primitive restart not to occur when it should. The fact that it works some of the time is rather frightening.
