2007-12-11Bump driver minor for relocation optimzationsKeith Packard
2007-12-11Allow relocation to be skipped when buffers don't move.Keith Packard
One of the costs of superioctl has been the need to perform relocations inside the kernel. The cost of mapping the buffers to the CPU and writing data is fairly high, especially if those buffers have been mapped and read by the GPU. If we assume that buffers don't move around very often, we can have the client compute the relocations itself using the previous GPU address. When that object doesn't move, the kernel can skip computing and writing the updated data. Here's a patch which adds a new field to struct drm_bo_info_req called 'presumed_offset', and a new DRM_BO_HINT_PRESUMED_OFFSET that is set when this field has been filled in by the client. There are two separate optimizations performed when the presumed_offset is correct: 1. i915_exec_reloc checks to see if all previous buffer offsets were guessed correctly. If so, there's no need for it to look at *any* of the relocations for a buffer. When this happens, it skips the whole relocation process, simply returning success. 2. i915_apply_reloc checks to see if the target buffer offset was guessed correctly. If so, it skips mapping the relocatee, computing the relocation and writing the value. If no relocations are needed, the relocatee should never be mapped to the CPU, and so the kernel shouldn't need to wait for any fences to pass.

2007-12-07Fix pipe<->plane mapping vs. vblank handling (again)Jesse Barnes
If drmMinor >= 6, the intel DDX driver will enable vblank events on both pipes. If drmMinor >= 10 on pre-965 chipsets, the intel DDX driver will swap the pipe<->plane mapping to allow for framebuffer compression on laptop screens. This means the secondary vblank counter (corresponding to pipe B) will be incremented when vblank interrupts occur. Now Mesa waits for vblank events on whichever plane has a greater portion of the displayed window. So it will happly ask to wait for the primary counter even though that one won't increment. So we can fix this in either the DDX driver, Mesa or the kernel (though I thought we already had several times). Since current (and previous) userspace assumes it's talking about a pipe == plane situation and now uses planes when talking to the kernel, we should probably just hide the mapping details there (indeed they already are hidden there for vblank swaps), which this patch does. So as far as userland is concerned, whether we call things planes or pipes is irrelevant, as long as kernel developers understand that userland hands them planes and they have to figure out which pipe that corresponds to (which will typically be the same on 965+ hardware and reversed on pre-965 mobile chips).

We needed to specifically check for driver support and test the correct vbl_received value. Also pulled over support for _DRM_VBLANK_NEXTONMISS from the linux code.
