3464f11496 Revert "drm/radeon/kms: disable HDMI audio for now on rv710/rv730"
This commit "disabled" audio on RV710 and RV740 only, leaving RV770 and RV730.
The order is: CHIP_RV770 < CHIP_RV730 < CHIP_RV710 < CHIP_RV740.

It is not needed anway, as we do not even try to enable audio on RV770 and
newer. We call initializing function in r600.c only, not in rv770.c.

If there is something causing green tinges, it's HDMI mode setting for encoder
and I will try to debug that.

566d84d172 drm/radeon: r100/r200 ums: block ability for userspace app to trash 0 page and beyond
radeon's have a special ability to passthrough writes in their internal
memory space directly to PCI, this ability means that if some of the internal
surfaces like the depth buffer point at 0x0, any writes to these will
go directly to RAM at 0x0 via PCI busmastering.

Now mesa used to always emit clears after emitting state, since the
radeon mesa driver was refactored a year or more ago, it was found it
could generate a clear request without ever sending any setup state to the
card. So the clear would attempt to clear the depth buffer at 0x0, which
would overwrite main memory at this point. fs corruption ensues.

Also once one app did this correctly, it would never get set back to 0
making this messy to reproduce.

The kernel should block this from happening as mesa runs without privs,
though it does require the user be connected to the current running X session.

This patch implements a check to make sure the depth offset has been set
before a depth clear occurs and if it finds one it prints a warning and
ignores the depth clear request. There is also a mesa fix to avoid sending
the badness going into mesa.

This only affects r100/r200 GPUs in user modesetting mode.

b4fe945405 drm/radeon: Fix memory allocation failures in the preKMS command stream checking.
Allocation of single large block of memory may fail under memory
presure. drm_buffer object can hold one large block of data in
multiple independ pages which preents alloation failures.

This patch converts all access to command stream to use drm_buffer
interface. All direct access to array has to go tough drm_buffer
functions to get correct pointer.

Outputting the command stream to ring buffer needs to be awear of
the split nature of drm_buffer. The output operation requires the
new OUT_RING_DRM_BUFFER.

Previous code mixed case 2 & 3 in a single one leading to possible

fence status doesn't matter. Fence become active (ie has a meaning
for the ib code) once the ib is scheduled or free. This patch also
get rid of the alloc bitmap as it was overkill, we know go through

d594e46ace drm/radeon/kms: simplify memory controller setup V2
Get rid of _location and use _start/_end also simplify the
computation of vram_start|end & gtt_start|end. For R1XX-R2XX
we place VRAM at the same address of PCI aperture, those GPU
shouldn't have much memory and seems to behave better when
setup that way. For R3XX and newer we place VRAM at 0. For
R6XX-R7XX AGP we place VRAM before or after AGP aperture this
might limit to limit the VRAM size but it's very unlikely.
For IGP we don't change the VRAM placement.

Tested on (compiz,quake3,suspend/resume):
PCI/PCIE:RV280,R420,RV515,RV570,RV610,RV710
AGP:RV100,RV280,R420,RV350,RV620(RPB*),RV730
IGP:RS480(RPB*),RS690,RS780(RPB*),RS880

RPB: resume previously broken

V2 correct commit message to reflect more accurately the bug
and move VRAM placement to 0 for most of the GPU to avoid
limiting VRAM.

e803e8b262 drm/radeon/kms: make sure retry count increases.
In testing I've never seen it go past 1 retry anyways but better
safe than sorry.

Reported by Droste on irc.

ce36f00d59 drm/radeon/kms/atom: use get_unaligned_le32() for ctx->ps
Noticed on a DEC Alpha.

Start up into console mode caused 15 unaligned accesses, and starting X
caused another 48.

6b79b264ce No need to patch AMD-provided drivers/gpu/drm/radeon/atombios.h
This is partial revert of commit 9404c9c392d5 ("Fix misspelling of "should"
and "shouldn't" in comments"). According to Dave Airlie:

	"Can we drop any cleanups to atombios.h? This file comes from
	AMD and we normally drop it into place, so they just get overwritten
	next time."

7cb72ef4d3 drm/radeon/kms: fix r600/r700 cs checker to avoid double kfree
radeon_cs kfree the tracker structure but for r6xx/r7xx we want
to kfree it inside the parse function because we share it with
the UMS code path. Set tracker to NULL after freeing it will
avoid double free.

8256856568 drm/radeon/kms: set gart pages to invalid on unbind and point to dummy page
this uses a new entrypoint to invalidate gart entries instead of using 0.
Changed to rather than pointing to 0 address point empty entry to dummy
page. This might help to avoid hard lockup if for some wrong
reasons GPU try to access unmapped GART entry.

I'm not 100% sure this is going to work, we probably need to allocate
a dummy page and point all the GTT entries at it similiar to what AGP does.
but we can test this first I suppose.

03047cdf72 drm/radeon/kms: Test rdev->bios centrally in combios_get_table_offset().
It's happened time and time again (most recently with the support for EDID
hardcoded in the BIOS ROM) that new code didn't check for rdev->bios being
non-NULL before triggering dereferences of it. This would result in an
oops/panic on setups with no BIOS ROM. Hopefully this central test will be
more robust.
