Pull drm updates from Dave Airlie:
"Lots of stuff all over, some new AMD IP support and gang submit

Register GT0_PERF_LIMIT_REASONS (0x1381a8) is available only for
Gen11+. Therefore ensure perf_limit_reasons sysfs files are created only
for Gen11+. Otherwise on Gen < 5 accessing these files results in the
following oops:
<1> [88.829420] BUG: unable to handle page fault for address: ffffc90000bb81a8
<1> [88.829438] #PF: supervisor read access in kernel mode
<1> [88.829447] #PF: error_code(0x0000) - not-present page
This patch is a backport of the drm-tip commit 0d2d201095e9
("drm/i915: Perf_limit_reasons are only available for Gen11+") to
drm-intel-fixes. The backport is not identical to the original, it only
includes the sysfs portions of if. The debugfs portion is not available
in drm-intel-fixes so has not been backported.

Throttling here refers to the GT frequency being clipped. Each of
the throttle reason attributes will have a 0 or 1 value depending
upon whether there is throttling and also the specific reason for
it.
The following is a brief description of the sysfs throttle
frequency attributes added:
- throttle_reason_status: when set indicates that there is GT
frequency clipping.
- throttle_reason_pl1: when set indicates that PBM PL1 (platform
or package PL1) has caused GT frequency clipping.
- throttle_reason_pl2: when set indicates that PBM PL2 or PL3
(platform or package PL2 or PL3) has caused GT frequency
clipping.
- throttle_reason_pl4: when set indicates that PL4 or IccMax has
caused GT frequency clipping.
- throttle_reason_thermal: when set indicates that Thermal event
has caused GT frequency clipping.
- throttle_reason_prochot: when set indicates that PROCHOT# has
caused GT frequency clipping.
- throttle_reason_ratl: when set indicates that Running Average
Thermal Limit has caused GT frequency clipping.
- throttle_reason_vr_thermalert: when set indicates that Hot VR
(any processor VR) has caused GT frequency clipping.
- throttle_reason_vr_tdc: when set indicates that VR TDC
(Thermal Design Current) has caused GT frequency clipping.

Now tiles have their own sysfs interfaces under the gt/
directory. Because RPS is a property that can be configured on a
tile basis, then each tile should have its own interface
The new sysfs structure will have a similar layout for the 4 tile

The existing interfaces have been kept in their original location
to preserve the existing ABI. They act on all the GTs: when
writing they loop through all the GTs and write the information
on each interface. When reading they provide the average value
from all the GTs.
This patch is not really adding exposing new interfaces (new
ABI) other than adapting the existing one to more tiles. In any
case this new set of interfaces will be a basic tool for system
managers and administrators when using i915.
