c4932d7956 drm/i915/psr: Don't avoid PSR when PSR2 conditions are not met. 
We can still use PSR1 when PSR2 conditions are not met.

So, let's split the check in a way that we make sure has_psr
gets set independently of PSR2 criteria.

v2: Duh! Handle proper return to avoid breaking PSR2.
v3: (DK):
	- better name for psr2 conditions check function
	- Don't remove FIXME block and psr2.support check.
	- Add a debug message to show us what PSR or PSR2 is
	  getting enabled now we have ways to enabled PSR on
	  PSR2 panels.
	- s/PSR2 disabled/PSR2 not enabled

06d058e1a0 drm/i915/psr: Check for power state control capability. 
eDP spec says - "If PSR/PSR2 is supported, the SET_POWER_CAPABLE bit in the
EDP_GENERAL_CAPABILITY_1 register (DPCD Address 00701h, bit d7) must be set
to 1."

Reject PSR on panels without this cap bit set as such panels cannot be
controlled via SET_POWER & SET_DP_PWR_VOLTAGE register and the DP source
needs to be able to do that for PSR.

Thanks to Nathan for debugging this.

Panel cap checks like this can be done just once, let's fix this
when PSR dpcd init movement lands.

b891d5e46c drm/i915/psr: New power domain for AUX IO. 
PSR on CNL requires AUX IO wells to be kept on and the existing AUX domain
for AUX-A enables DC_OFF well too. This is not required, so add a new
AUX_IO_A domain for AUX-A to allow DC states to remain enabled. Other AUX
channels re-use the existing AUX domains.

v4: Reword comment (Rodrigo and Ville)
    Rename _get and _put functions to include aux_io substring(Rodrigo)
    Remove unnecessary diff that got included.
v3: Extract aux domain selection into a function (Ville)
v2: Add AUX IO domain only for AUX-A
    Rebased on top of Ville's AUX series.

5028a4fb7d drm/i915/guc: Fill preempt context once at init time 
Since we're inhibiting context save of preempt context, we're no longer
tracking the position of HEAD/TAIL. With GuC, we're adding a new
breadcrumb for each preemption, which means that the HW will do more and
more breadcrumb writes. Eventually the ring is filled, and we're
submitting the preemption context with HEAD==TAIL==0, which won't result
in breadcrumb write, but will trigger hangcheck instead.
Instead of writing a new preempt breadcrumb for each preemption, let's
just fill the ring once at init time (which also saves a couple of
instructions in the tasklet).

v2: Assert that context save restore is inhibited, don't assert on ring
    alignment. (Chris)
v3: Cleanup checkpatch.

ec3fe391bd drm/ttm: check if free mem space is under the lower limit 
the free mem space and the lower limit both include two parts:
system memory and swap space.

For the OOM triggered by TTM, that is the case as below:
first swap space is full of swapped out pages and soon
system memory also is filled up with ttm pages. and then
any memory allocation request will run into OOM.

to cover two cases:
a. if no swap disk at all or free swap space is under swap mem
   limit but available system mem is bigger than sys mem limit,
   allow TTM allocation;

b. if the available system mem is less than sys mem limit but
   free swap space is bigger than swap mem limit, allow TTM
   allocation.

v2: merge two memory limit(swap and system) into one
v3: keep original behavior except ttm_opt_ctx->flags with

v4: always set force_alloc as tx->flags & TTM_OPT_FLAG_FORCE_ALLOC

This patch fix the following build warnings:
  CC [M]  drivers/gpu/drm/amd/amdgpu/amdgpu_drv.o
cc1: warning: ../display/: No such file or directory [-Wmissing-include-dirs]
cc1: warning: ../display/include: No such file or directory [-Wmissing-include-dirs]

cc1: warning: ../display/: No such file or directory [-Wmissing-include-dirs]
cc1: warning: ../display/include: No such file or directory [-Wmissing-include-dirs]
[...]
This warning is shown for each file in amdgpu directory, so it spams a lot.

bcb0b981c5 drm/radeon: insist on 32-bit DMA for Cedar on PPC64/PPC64LE 
In radeon_device_init, set the need_dma32 flag for Cedar chips
(e.g. FirePro 2270).  This fixes, or at least works around, a bug
on PowerPC exposed by last year's commits

8e3f1b1d82 (Russell Currey)

and

253fd51e2f (Alistair Popple)

which enabled the 64-bit DMA iommu bypass.

This caused the device to freeze, in some cases unrecoverably, and is
the subject of several bug reports internal to Red Hat.
