intel_audio_dump/bdw: dump debug registers for audio immediate commands

This patch dumps debug registers to check audio immediate command, response
and status.

The audio driver will fall back into immediate command mode if normal
communication between controller and codec is dead.

intel_audio_dump/bdw: add support for Broadwell

This patch renames Haswell audio dump function and reuses it for Broadwell.

Since Haswell, audio registers are moved from the south display engine to the
north display engine. And the audio register layout is same for Haswell and its
successors like Broadwell.

rendercopy/bdw: Fix the original implementation

For posterity, I've squashed these commits against Damien's request.

rendercopy/gen8: Fix the include guards

rendercopy/gen8: Update the 3DSTATE_MULTISAMPLE opcode

The opcode has changed in BDW.

rendercopy/gen8: Add the VF_TOPOLOGY state

The primitive type has moved out of the 3DPRIMITIVE to its own state,
VF_TOPOLOGY.

rendercopy/gen8: Fixup 3STATE_PS

Update the state to the latest BSpec, in particular the thread count was
using a wrong shift and we were missing kernel2 offset.

rendercopy/gen8: Update 3DSTATE_BASE_ADDRESS

This state has seen its fields moved around a bit, follow the BSpec.

rendercopy/gen8: Allocate 64 VUEs

The simulator screams at us if we try to allocate less than that.

rendercopy/gen8: Surface states have to be 64 bytes a aligned

rendercopy/gen8: Vertical/horizontal align 2 does not exist any more

So set them to 4. This should not matter with rendercopy (which is not
using compressed textures), but it makes the simulator moan.

rendercopy/gen8: Make sure the vertex buffer is 8 bytes aligned

rendercopy/gen8: Adjust 3DSTATE_VERTEX_BUFFERS for gen8

The address of the buffer is now on 48 bits. Also the size was computed
as offset + size where the field is really the size of the buffer
itself, not the end address.

rendercopy/gen8: Update the SF/SBE states for gen8

gen8 has a few changes around those states and a new ones RASTER and
SBE_SWIZ.

rendercopy/gen8: Add the PS_EXTRA and PS_BLEND states

rendercopy/gen8: Fix building with DEBUG_RENDERCOPY defined

The forward declaration was missing the final ';'. Let's move the whole
function at the top instead.

rendercopy/gen8: Update the PS and CONSTANT_PS states

rendercopy/gen8: Fix the red channel selection

Make it output red.

rendercopy/gen8: Update the write -1 shader

With the latest assembler changes from Haihao.

rendercopy/gen8: Remove blit.g8a

There is no diff between this file and blig.g7a. Remove it.

rendercopy/gen8: Fix the surface relocation offset

The surface base address is now at dwords 8/9 so the relocation has to
mirror the change.

rendercopy/gen8: Add the VF_INSTANCING state

Should work without, but doesn't hurt to add it.

rendercopy/gen8: Set the Attribule enable field in PS_EXTRA

When the SF is set up to output some attributes, the pixel shader also
have to be told there's attributes to care about.

rendercopy/gen8: Set the force bits to read URB offset/length

If we want to override the URB offset/length in the SBE state itself, we
need to set the force bits on (new in gen8)

tests/pc8: add modeset -stress-no-wait tests

Used to trigger a racing condition between mode setting and
enabling/disabling PC8. The modeset-lpsp-stress-no-wait test should
fail on Kernels without the fix I just wrote today.

tests/pc8: add modeset-lpsp and modeset-non-lpsp

The goal of these tests is to exercise the combination of power well
enabling/disabling and PC8 enabling/disabling. The modeset-non-lpsp
test exposes a silent bug on the current code that can just be
detected with the Runtime D3 patches. The Kernel patch that fixes the
bug will add a WARN to unmute it on the PC8-only case.

lib/drmtest: Scream harder when igt_exit isn't called for subtest tests

We really need this since otherwise the magic return value handling
for running testcases with piglit (or on QA's validation
infrastructure) doesn't work properly.

We need to be careful though to only install this check on success.

See also the previous commits to sprinkle igt_exit() calls over all
the tests that missed it.
