drm/i915/icl: Fix port B combo PHY context loss after DC transitions
On ICL DMC/PCODE retains the HW context only for port A across DC
transitions, for the other port B combo PHY, it doesn't. So we need to
do this manually after exiting from DC6. Do the reinit even after
exiting from DC5, it won't hurt since we only reinit the PHY in case
it's needed (in case it was disabled to begin with).
As can be guessed from the bugzilla report leaving the PHY uninited will
lead to a later timeout during the port B specific AUX and DDI_IO power
well enabling.

drm/i915: Add short HPD IRQ storm detection for non-MST systems
Unfortunately, it seems that the HPD IRQ storm problem from the early
days of Intel GPUs was never entirely solved, only mostly. Within the
last couple of days, I got a bug report from one of our customers who
had been having issues with their machine suddenly booting up very
slowly after having updated. The amount of time it took to boot went
from around 30 seconds, to over 6 minutes consistently.
After some investigation, I discovered that i915 was reporting massive

The customer's system in question has a GM45 GPU, which is apparently
well known for hotplugging storms.
So, workaround this impressively broken hardware by changing the default
HPD storm threshold from 5 to 50. Then, make long IRQs count for 10, and
short IRQs count for 1. This makes it so that 5 long IRQs will trigger
an HPD storm, and on systems with short HPD storm detection 50 short
IRQs will trigger an HPD storm. 50 short IRQs amounts to 100ms of
constant pulsing, which seems like a good middleground between being too
sensitive and not being sensitive enough (which would cause visible
stutters in userspace every time a storm occurs).
And just to be extra safe: we don't enable this by default on systems
with MST support. There's too high of a chance of MST support triggering
storm detection, and systems that are new enough to support MST are a
lot less likely to have issues with IRQ storms anyway.
As a note: this patch was tested using a ThinkPad T450s and a Chamelium
to simulate the short IRQ storms.
Changes since v1:
- Don't use two separate thresholds, just make long IRQs count for 10
each and short IRQs count for 1. This simplifies the code a bit

- Document @long_hpd in intel_hpd_irq_storm_detect, no functional
changes

Currently in intel_hpd_irq_storm_detect() when we detect that the last
recorded hotplug wasn't within the period defined by
HPD_STORM_DETECT_DELAY, we make the mistake of resetting the HPD count
to 0 without incrementing it. This results in us only enabling storm
detection when we go +2 above the threshold, e.g. an HPD threshold of 5
would not trigger a storm until we reach a total of 7 hotplugs.
So: rework the code a bit so we reset the HPD count when
HPD_STORM_DETECT_DELAY has passed, then increment the count afterwards.
Also, clean things up a bit to make it easier to undertand.

needed to delay the EMIT_INVALIDATE by several flushes. It is important
to note that it is the EMIT_INVALIDATE as opposed to the EMIT_FLUSH that
needs the delay as opposed to what one might first expect -- that the
delay is required for the TLB invalidation to take effect (one presumes
to purge any CS buffers) as opposed to a delay after flushing to ensure
the writes have landed before triggering invalidation.

mm, drm/i915: mark pinned shmemfs pages as unevictable
The i915 driver uses shmemfs to allocate backing storage for gem
objects. These shmemfs pages can be pinned (increased ref count) by
shmem_read_mapping_page_gfp(). When a lot of pages are pinned, vmscan
wastes a lot of time scanning these pinned pages. In some extreme case,
all pages in the inactive anon lru are pinned, and only the inactive
anon lru is scanned due to inactive_ratio, the system cannot swap and
invokes the oom-killer. Mark these pinned pages as unevictable to speed
up vmscan.
Export pagevec API check_move_unevictable_pages().

Plane input CSC needs to be enabled to convert frambuffers from

This patch defines the co-efficient values for YUV to RGB conversion

the plane input csc unit in hardware.
This has been verified and tested by Maarten and the change is working
as expecpted.
v2: Addressed Maarten's and Ville's review comments and added the
coefficients in a 2D array instead of independent Macros.
v3: Added individual coefficient matrix (9 values) instead of 6
register values as per Maarten's comment. Also addresed a shift
issue with B channel coefficient.
v4: Added support for Limited Range Color Handling
v5: Fixed Matt and Maarten's review comments.
v6: Added human readable matrix values for YUV to RGB Conversion along

v7: Refactored the code, move csc coefficient programming function to

drm/i915: Fix ilk+ watermarks when disabling pipes
We're no longer programming any watermarks when we're disabling
a pipe. That means ilk_wm_merge() & co. will keep considering
the any pipe that is getting disabled as still enabled. Thus we
either get no LP1+ watermakrs (ilk-ivb), or we get suboptimal
ones (hsw-bdw).
This seems to have been broken by commit
b6b178a77210 ("drm/i915:
Calculate ironlake intermediate watermarks correctly, v2."). Before
that we apparently had some difference between the intermediate
and optimal watermarks and so we would program the optiomal ones.
Now intermediate and optimal are identical for disabled pipes
and so we don't program either.
Fix this by programming the intermediate watermarks even for
disabled pipes. We were already doing that for skl+. We'll
leave out gmch platforms for now since those do the merging
in a different manner and should work as is. We'll want to
unify this eventually, but play it safe for now and just put
in a FIXME.

great for widely used registers. However, the palette registers are only
used in one function, i9xx_load_luts_internal(), and only for GMCH
platforms, wasting device info. Replace palette_offsets with _PICK() in
palette register definition.
While the use of _PICK() does not check for pipe C existence, neither
does the current offset array usage, and leads to bogus address when
pipe C is passed to PALETTE() on non-CHV. Using _PICK() at least leads
to a sensible register offset, just non-existing on non-CHV. Either way,
this shouldn't happen anyway.

Most of the AUX_CH_CTL flags are concerned with DP AUX transfer
parameters. As opposed to this the flag specifying the thunderbolt vs.
non-thunderbolt mode of the port is not related to AUX transfers at all
(rather it's repurposed to enable either TBT or non-TBT PHY HW blocks).
The programming has to be done before enabling the corresponding AUX
power well, so make it part of the power well code.

drm/amdgpu: Fix skipping hangged job reset during gpu recover.
Problem:
During GPU recover DAL would hang in

Fix:
Turns out there was a typo introduced by
3320b8d drm/amdgpu: remove job->ring which caused skipping
amdgpu_fence_driver_force_completion and so the hangged job
was never force signaled and this would cause the hang later in DAL.

drm/i915/dp: Add helpers for Compressed BPP and Slice Count for DSC
This patch adds helpers for calculating the maximum compressed BPP
supported with small joiner.
This also adds a helper for calculating the slice count in case
of small joiner.
These are inside intel_dp since they take into account hardware
limitations.
v6:
* Take mode_clock and mode_hdisplay as input arguments
so that this can be called in intel_dp_mode_valid (Manasi)
v5:
* Get the max slice width from DPCD
* Check against Min_Slice_width of 2560 (Anusha)
v4:
* #defines for PPR in slice count helper (Gaurav)
v3:
* Simply logic for bpp (DK)
* Limit the valid slice count by max supported by Sink (Manasi)
v2:
* Change the small joiner RAM buffer constant as bspec changed (Manasi)
* rename it as SMALL_JOINER since we are not enabling
big joiner yet (Anusha)

drm/i915/dp: Cache the DP/eDP DSC DPCD register set on Hotplug/eDP Init
DSC is supported on eDP starting GEN 10 display (on GLK) and on DP starting
GEN 11.
This patch implements the discovery phase of DSC. On hotplug,
source reads the DSC DPCD register set (0x00060 - 0x0006F) to
read the decompression capabilities of the sink device.
This entire block of registers is cached in intel_dp so that
capability information can be used during DSC configuration
phase during compute_config phase of the modeset.
For eDP, this caching happens during the eDP initialization.
This caching is done only for eDP and DP rev >= 1.4
v5:
* Fix the block comment (Gaurav)
* Fix the commit message DSC DPCD addresses (Gaurav)

HX TX: Ensure that host does not continuously transmit in the HS

transmission and allow the link to enter into LP state.
LP RX: Monitor the length of LP receptions from Peripheral. If timeout
happens then host will drive the stop state onto all data lanes (only
Data Lane 0 should be receiving anything from the Peripheral). This
effectively takes back ownership of the bus transmit in the HS state.
