If we want to be able to hit the instmem fast-path in a few trickier cases,
we need to be more flexible with when we can initialise BAR2 access.
There's probably a decent case to be made for merging BAR/INSTMEM into BUS,
but that's something to ponder another day.
Flushes have been added after the write to bind the instance block,
as later commits will reveal the need for them.

NVIDIA call it BAR2, Linux APIs treat it as BAR3 due to BAR1 being a
64-bit BAR, which I presume take two slots or something.
No actual code changes here, just to make future commits less messy.

Will already be done by MMU as a result of the PT writes that occur

RM appears to do this really early in its initialisation, before DEVINIT.

The fan control mode can either be FDO_PWM_MODE_STATIC or FDO_PWM_MODE_STATIC_RPM.
Setting it as AMD_FAN_CTRL_AUTO will cause the fan spin faster wrongly.
This can be reproduced by:
'# cat /sys/class/hwmon/hwmon0/pwm1
38
'# cat /sys/class/hwmon/hwmon0/pwm1_enable
2
'# echo "2" > /sys/class/hwmon/hwmon0/pwm1_enable
'# cat /sys/class/hwmon/hwmon0/pwm1
122
The fan speed get faster wrongly even with its original mode echo back.

+ preemption support for a5xx[1][2]
+ display fixes for 8x96 (snapdragon 820) including fixes for 4k scanout
(hwpipe assignment re-work to handle multiple hwpipe assigned to plane
for wide scanout)
+ async cursor plane updates and fixes
+ refactor adreno_bind/hwinit.. still defer fw loading until device open,
but move clk/irq/etc to probe/bind time to fix issues when fw isn't
present in filesys
+ clk/dt bindings cleanups w/ backward compat via msm_clk_get() (dt docs
part ack'ed by Rob Herring)
+ fw loading re-work with helper to handle either /lib/firmware/qcom/$fw
or /lib/firmware/$fw.. background, we've started landing fw for some of
generations in linux-firmware, but there is a preference to put fw files
under 'qcom' subdirectory, which is not what was done on android or for
people who copied fw from android. So now we first look in qcom subdir
and then fallback to the original location.
+ bunch of GPU debugging enhancements, to dump full cmdline of processes
that trigger faults, and to add a new debugfs to capture cmdstream of
just submits that triggered faults.. both quite useful for piglit ;-)

When kfd suspending on APU, we do not need to call
amd_iommu_unbind_pasid(), because pasid will be unbound automatically
when power goes off.
On the other hand, calling amd_iommu_unbind_pasid() will trigger
kfd_process_iommu_unbind_callback() if the process is not terminating.
By design, kfd_process_iommu_unbind_callback() should only be called
for process terminating. So we would rather not to call
amd_iommu_unbind_pasid() when suspending.

This is an extension of Commit 7c20d213dd3c ("drm/vmwgfx: Work
around mode set failure in 2D VMs")
With Wayland desktop and atomic mode set, during the mode setting
process there is a moment when two framebuffer sized surfaces
are being pinned. This was not an issue with Xorg.
Since this only happens during a mode change, there should be no
performance impact by increasing allowable mem_size.

In case the object has changed tiling between calls to execbuf, we need
to check if the existing offset inside the GTT matches the new tiling
constraint. We even need to do this for "unfenced" tiled objects, where
the 3D commands use an implied fence and so the object still needs to
match the physical fence restrictions on alignment (only required for
gen2 and early gen3).
In commit 2889caa92321 ("drm/i915: Eliminate lots of iterations over
the execobjects array"), the idea was to remove the second guessing and
only set the NEEDS_MAP flag when required. However, the entire check
for an unusable offset for fencing was removed and not just the
secondary check. I.e.
/* avoid costly ping-pong once a batch bo ended up non-mappable */
if (entry->flags & __EXEC_OBJECT_NEEDS_MAP &&
!i915_vma_is_map_and_fenceable(vma))
return !only_mappable_for_reloc(entry->flags);
was entirely removed as the ping-pong between execbuf passes was fixed,
but its primary purpose in forcing unaligned unfenced access to be
rebound was forgotten.

The function for byteswapping the data send to/from atombios was buggy for
num_bytes not divisible by four. The function must be aware of the fact
that after byte-swapping the u32 units, valid bytes might end up after the
num_bytes boundary.
This patch was tested on kernel 3.12 and allowed us to sucesfully use
DisplayPort on and Radeon SI card. Namely it fixed the link training and
EDID readout.
The function is patched both in radeon and amd drivers, since the functions
and the fixes are identical.

To acquire all modeset locks requires a ww_ctx to be allocated. As this
is the legacy path and the allocation small, to reduce the changes
required (and complex untested error handling) to the legacy drivers, we
simply assume that the allocation succeeds. At present, it relies on the
too-small-to-fail rule, but syzbot found that by injecting a failure
here we would hit the WARN. Document that this allocation must succeed
with __GFP_NOFAIL.
