commit b852c985010a77c850b7548d64bbb964ca462b02 upstream.
HW ACR support may have issues on some older chips, so
use SW ACR for now until we've tested further.

commit ee0fec312a1c4e26f255955da942562cd8908a4b upstream.
Use the hw generated values rather than calculating
them in the driver. There may be some older r6xx
asics where this doesn't work correctly. This remains
to be seen.

commit e7d12c2f98ae1e68c7298e5028048d150fa553a1 upstream.
The drm code that calculates the 1001 clocks rounds up
rather than truncating. This allows the table to match
properly on those modes.

commit 4cc948b94a222c310ae089c36718aac7a03aec90 upstream.
If we fail to allocate an indirect buffer (ib) when updating
the ptes, return an error instead of trying to use the ib.
Avoids a null pointer dereference.

commit 97b6ff6be9da7675aab339334fda996d6c5077d9 upstream.
GPU with low amount of ram can fails at pinning new framebuffer before
unpinning old one. On such failure, retry with unpinning old one before
pinning new one allowing to work around the issue. This is somewhat
ugly but only affect those old GPU we care about.

commit b2ea8ef559b4d94190009f3651b5b3ab7c05afd3 upstream.
Apparently they need the same treatment as primary planes. This fixes
modesetting failures because of stuck cursors (!) on Thomas' i830M
machine.
I've figured while at it I'll also roll it out for the ivb 3 pipe
version of this function. I didn't do this for i845/i865 since Bspec
says the update mechanism works differently, and there's some
additional rules about what can be updated in which order.

having LVDS but the hardware is not populated. This patch adds them to
the list of such systems. Patch is against 3.11.4

believe they own the enabled encoder and so we attempt to both enable
and disable DPMS on the encoder, leading to hilarity and an OOPs:

This reverts commit b2a9484006875ecd7d94582e7bcb72a02682be92.
Commit 99d79aa2f3b7729e7290e8bda5d0dd8b0240ec62 (backported by
b2a9484006875ecd7d94582e7bcb72a02682be92) was supposed to fix rv6xx_asic
struct.
In kernel 3.10 we didn't have that struct yet, so the original patch
should never be backported to the 3.10. Accidentally it has applied and
modified different struct (r520_asic) that shouldn't have any HDMI
callbacks at all.

commit 0ce99f749b3834edeb500e17d6ad17e86b60ff83 upstream.
Apparently Bspec is wrong in this case here even for gm45. Note that
Bspec is horribly misguided on i965g/gm, so we don't have any other
data points besides that it seems to make machines work better.
With this changes all the bits in PORT_HOTPLUG_STAT for the digital
ports are ordered the same way. This seems to agree with what register
dumps from the hpd storm handling code shows, where the LIVE bit and
the short/long pulse STATUS bits light up at the same time with this
enumeration (but no with the one from Bspec).
Also tested on my gm45 which has two DP+ ports, and everything seems
to still work as expected.

commit 0eb3448aa6b31fbf24c31756aba7940cac5ad6b8 upstream.
Prevent NULL pointer dereference in case when radeon_ring_fini() did it's job.
Reading of r100_cp_ring_info and radeon_ring_gfx debugfs entries will lead to a KP if ring buffer was deallocated, e.g. on failed ring test.
Seen on PA-RISC machine having "radeon: ring test failed (scratch(0x8504)=0xCAFEDEAD)" issue.

There is no clear cut rules or specs for the retry interval, as there

drm/i915: set up PIPECONF explicitly for i9xx/vlv platforms
Ville brough up the idea that this is just the pipe A quirk gone
wrong.
Note that after resume the bios might or might not have enabled pipe A
already. We have a bit of magic to make sure that on resume we set up
a decent mode for pipe A, but I fear if I just smash pipe A to always
on we'd enable it in a bogus state and hang the hw. Hence the
readback.
v2: Clarify the logic a bit as suggested by Chris. Also amend the
commit message to clarify why we don't unconditionally enable the
pipe.

commit 1062b81598bc00e2f6620e6f3788f8f8df2f01e7 upstream.
The native TV encoder has it's own flags to adjust sync modes and
enabled interlaced modes which are totally irrelevant for the adjusted
mode. This worked out nicely since the input modes used by both the
load detect code and reported in the ->get_modes callbacks all have no
flags set, and we also don't fill out any of them in the ->get_config
callback.
This changed with the additional sanitation done with
commit 2960bc9cceecb5d556ce1c07656a6609e2f7e8b0
Author: Imre Deak <imre.deak@intel.com>

drm/i915: make user mode sync polarity setting explicit
sinc now the "no flags at all" state wouldn't fit through core code
any more. So fix this up again by explicitly clearing the flags in the
->compute_config callback.
Aside: We have zero checking in place to make sure that the requested
mode is indeed the right input mode we want for the selected TV mode.
So we'll happily fall over if userspace tries to pull us. But that's
definitely work for a different patch series. So just add a FIXME
comment for now.

commit 91f3a6aaf280294b07c05dfe606e6c27b7ba3c72 upstream.
The OUTPUT_ENABLE action jumps past the point in the coder where
the data_offset is set on certain rs780 cards. This worked
previously because the OUTPUT_ENABLE action is always called
immediately after the ENABLE action so the data_offset remained
set. In 6f8bbaf568c7f2c497558bfd04654c0b9841ad57
(drm/radeon/atom: initialize more atom interpretor elements to 0),
we explictly reset data_offset to 0 between atom calls which then
caused this to fail. The fix is to just skip calling the
OUTPUT_ENABLE action on the problematic chipsets. The ENABLE
action does the same thing and more. Ultimately, we could
probably drop the OUTPUT_ENABLE action all together on DCE3
asics.

commit fb93df1c2d8b3b1fb16d6ee9e32554e0c038815d upstream.
The table has the following format:
typedef struct _ATOM_SRC_DST_TABLE_FOR_ONE_OBJECT //usSrcDstTableOffset pointing to this structure
{
UCHAR ucNumberOfSrc;
USHORT usSrcObjectID[1];
UCHAR ucNumberOfDst;
USHORT usDstObjectID[1];
}ATOM_SRC_DST_TABLE_FOR_ONE_OBJECT;
usSrcObjectID[] and usDstObjectID[] are variably sized, so we
can't access them directly. Use pointers and update the offset
appropriately when accessing the Dst members.

commit e5b9e7503eb1f4884efa3b321d3cc47806779202 upstream.
Also add a new RADEON_INFO query to check that CP DMA packets are
supported on the compute ring.
CP DMA has been supported since the 3.8 kernel, but due to an oversight
we forgot to teach the CS checker that the CP DMA packet was legal for
the compute ring on Southern Islands GPUs.
This patch fixes a bug where the radeon driver will incorrectly reject a legal
CP DMA packet from user space. I would like to have the patch
backported to stable so that we don't have to require Mesa users to use a
bleeding edge kernel in order to take advantage of this feature which
is already present in the stable kernels (3.8 and newer).
v2:
- Don't bump kms version, so this patch can be backported to stable
kernels.

Commit ea9197cc323839ef3d5280c0453b2c622caa6bc7 effectively enabled the

v2 (Ben Skeggs): the offending line was likely a thinko, removed it for
all chipsets (tested nv50 and nve6 to cover entire range) and added
some additional debugging.

commit 182b17c8dc4e83aab000ce86587b6810e515da87 upstream.
After a vmalloc failure in ttm_dma_tt_alloc_page_directory(),
ttm_dma_tt_init() will call ttm_tt_destroy() to cleanup, and end up
inside the driver's unpopulate() hook when populate() has never yet
been called.
On nouveau, the first issue to be hit because of this is that
dma_address[] may be a NULL pointer. After working around this,
ttm_pool_unpopulate() may potentially hit the same issue with
the pages[] array.
It seems to make more sense to avoid calling unpopulate on already
unpopulated TTMs than to add checks to all the implementations.
