| | | | | | | | | | | | | | | | | | | | | | | | | | This patch corrects a pretty big oversight in the KMS code for 965+ chips. The current code is missing tiled surface register programming, so userland can allocate a tiled surface and use it for mode setting, resulting in corruption. This patch fixes that, allowing for tiled front buffers on 965+.

Since we have userland with expectations that the swizzle enums let it pread and pwrite contents accurately, we can't expose a new swizzle enum for bit 17 (which it would have to GTT map to handle), so we handle it down in pread and pwrite by swizzling the copy when bit 17 of the page address is set.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We create a debugfs node (i915_ringbuffer_data) to expose a hex dump of the ring buffer itself. We also expose another debugfs node (i915_ringbuffer_info) with information on the state (i.e. head, tail addresses) of the ringbuffer. For batchbuffer dumping, we look at the device's active_list, dumping each object which has I915_GEM_DOMAIN_COMMAND in its read domains. This is all exposed through the dri/i915_batchbuffers debugfs file with a header for each object (giving the objects gtt_offset so that it can be matched against the offset given in the BATCH_BUFFER_START command.

Changes: - fix a copy&paste error in i8xx fence reg setup. It resulted in an at most a 512KB offset of the fence reg window, so was only visible sometimes. - add tests for stride and object size constrains (also for i915 and 1965 class hw). Userspace seems to have an of-by-one bug there, which changes the fence size by at most 512KB due to an overflow. - because i8xx hw is quite old (and therefore not as well-tested) I left 2 debug WARN_ONs in the i8xx fence reg setup code to hopefully catch any further overflows in the bit-fields. Lastly there's one small change to make the alignment checks more consistent.
