2013-04-04	intel-decode: Fix gen6 HIER_DEPTH_BUFFER decoding	Daniel Vetter
	It accidentally used the cmd id for the gen7 command and had an outdated lenght field. Spotted while trying to make sense of an ivb error_state from mesa 7.11 ... Reviewed-by: Eric Anholt <eric@anholt.net> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2012-06-27	intel/decode: fix the reference file for	Ben Widawsky
	I mistakenly "fixed" a bad decode with commit 7d0a1d5ebbe2c6aecd96eef94b0af038858a0178 Author: Ben Widawsky <ben@bwidawsk.net> Date: Sun Jun 24 20:35:57 2012 -0700 intel/decode: VERTEX_ELEMENT_STATE, 1 means valid However the actual fix is just to update the reference file, and include GEN7 in the decode. Props to Eric Anholt for putting the test in distcheck, or else I wouldn't have caught this. Signed-off-by: Ben Widawsky <ben@bwidawsk.net>
2012-03-10	intel: Add per-dword decode of gen7 3DPRIMITIVE.	Eric Anholt

2012-02-22	intel: Import a new batchbuffer for the gen7 test.	Eric Anholt
	This one doesn't have the 3DSTATE_HIER_DEPTH_BUFFER bug that the previous one did. Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2012-02-22	intel: Add decode for gen7 3DSTATE_WM.	Eric Anholt
	This requires pulling the gen6 3DSTATE_WM out to a function so it doesn't override gen7's handler. v2: Fix pasteo in interpreting ZW interpolation (thanks danvet!). Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2012-01-27	intel: Add minimal decode for remaining gen7 packets in use.	Eric Anholt
	This just gets packet name and length in place, with the remainder unfinished. I've long since finished the work that got me started fixing up the decode.
2012-01-27	intel: Add decode for gen7 constant buffer packets.	Eric Anholt

2012-01-27	intel: Add decode for gen7 state pointers.	Eric Anholt
	Since CC_STATE_POINTERS for gen6 and 7 are quite different but use the same opcode, move gen6 out to a helper function too, so we can use a helper function for gen7.
2012-01-27	intel: Add support for parsing gen7 URB packets.	Eric Anholt

2012-01-27	intel: Make most of the logic for 965 3d packet length checks table-driven.	Eric Anholt
	This puts the error message in a consistent location relative to the packet, and while I'm here I made the error message a bit more informative. Now, most static length packets need to just declare their length in the table and not worry.
2012-01-27	intel: Parse the correct length for gen7 3DSTATE_MULTISAMPLE.	Eric Anholt

2012-01-27	intel: Track the current packet location in the decode context.	Eric Anholt
	This is the start of plumbing the context through the decode callchain instead of the current 4 arguments.
2012-01-27	intel: Add a regression test for 2D decode, which I'm about to refactor.	Eric Anholt

2012-01-04	intel: Add regression tests for batch decode.	Eric Anholt
	The .batch was generated using the dump-a-batch branch of git://people.freedesktop.org/~anholt/mesa using glxgears on gen7 hardware, using INTEL_DEVID_OVERRIDE for non-gen7 (this means that offsets in the buffers for non-gen7 are 0!). The .ref was generated by: ./test_decode tests/gen7-3d.batch -dump. The .sh exists because you can't supply arguments to tests using the simple automake tests driver. Something reasonable could be done using automake's parallel-tests driver (in fact, a previous version of the patch did that), but I was concerned that: 1) The parallel-tests driver is documented to be unstable -- they may change interfaces on us later. 2) The parallel-tests driver hides the output of tests in .log files scattered all over the tree, which was ugly and more painful to work with. v2: Actually add the batch files, add a .gitignore for the *-new.txt files added after failures, and fix failure mode for undetected chipset name.
