baec997285 drm/i915/gvt: Only pin/unpin intel_context along with workload
One issue exposed after below commit with which the system will freeze
at suspend after vGPU is created (no need to activate the vGPU).
commit e6ba764802 ("drm/i915: Remove i915->kernel_context")

Old implementation pin the intel_context at setup_submission and
unpin it at clean_submission. So after some vGPU is created, the
intel_context is always pinned there although no workload using it.
It will then block i915 enter suspend state.

There is no need to pin it all the time. Pin/unpin it around workload
lifecycle is more reasonable. After GVT enabled suspend/resume, the
pinned intel_context will also get unpined when userspace put VM process
into suspend state since all workloads are retired, then it's safe to
unpin all intel_context for workloads created. So move the pin/unpin to
create_workload and destroy_workload, while still keep the
create/destroy in old place.

V2:
Rebase.

d7787cc04e drm/nouveau/kms/nv50-: Fix clock checking algorithm in nv50_dp_mode_valid()
While I thought I had this correct (since it actually did reject modes
like I expected during testing), Ville Syrjala from Intel pointed out
that the logic here isn't correct. max_clock refers to the max data rate
supported by the DP encoder. So, limiting it to the output of ds_clock (which
refers to the maximum dotclock of the downstream DP device) doesn't make any
sense. Additionally, since we're using the connector's bpc as the canonical BPC
we should use this in mode_valid until we support dynamically setting the bpp
based on bandwidth constraints.

https://lists.freedesktop.org/archives/dri-devel/2020-September/280276.html

For more info.

So, let's rewrite this using Ville's advice.

v2:
* Ville pointed out I mixed up the dotclock and the link rate. So fix that...
* ...and also rename all the variables in this function to be more appropriately
  labeled so I stop mixing them up.
* Reuse the bpp from the connector for now until we have dynamic bpp selection.
* Use use DIV_ROUND_UP for calculating the mode rate like i915 does, which we
  should also have been doing from the start

While I don't think anyone's likely using 3D output with nouveau, the next patch

rid of it and open-code it like before, while taking care to move the 3D frame

24d9422e26 drm/nouveau/kms/nv50-: Program notifier offset before requesting disp caps
Not entirely sure why this never came up when I originally tested this
(maybe some BIOSes already have this setup?) but the ->caps_init vfunc
appears to cause the display engine to throw an exception on driver
init, at least on my ThinkPad P72:

nouveau 0000:01:00.0: disp: chid 0 mthd 008c data 00000000 0000508c 0000102b

This is magic nvidia speak for "You need to have the DMA notifier offset
programmed before you can call NV507D_GET_CAPABILITIES." So, let's fix
this by doing that, and also perform an update afterwards to prevent
racing with the GPU when reading capabilities.

v2:
* Don't just program the DMA notifier offset, make sure to actually
  perform an update
v3:
* Don't call UPDATE()
* Actually read the correct notifier fields, as apparently the
  CAPABILITIES_DONE field lives in a different location than the main
  NV_DISP_CORE_NOTIFIER_1 field. As well, 907d+ use a different
  CAPABILITIES_DONE field then pre-907d cards.
v4:
* Don't forget to check the return value of core507d_read_caps()
v5:
* Get rid of NV50_DISP_CAPS_NTFY[14], use NV50_DISP_CORE_NTFY
* Disable notifier after calling GetCapabilities()

5cbd7685b2 drm/i915: Restore ILK-M RPS support
Restore RPS for ILK-M. We lost it when an extra HAS_RPS()
check appeared in intel_rps_enable().

Unfortunaltey this just makes the performance worse on my
ILK because intel_ips insists on limiting the GPU freq to
the minimum. If we don't do the RPS init then intel_ips will
not limit the frequency for whatever reason. Either it can't
get at some required information and thus makes wrong decisions,
or we mess up some weights/etc. and cause it to make the wrong
decisions when RPS init has been done, or the entire thing is
just wrong. Would require a bunch of reverse engineering to
figure out what's going on.

09a729b178 drm/i915/region: fix max size calculation
We are incorrectly limiting the max allocation size as per the mm
max_order, which is effectively the largest power-of-two that we can fit
in the region size. However, it's normal to setup the region or
allocator with a non-power-of-two size(for example 3G), which we should
already handle correctly, except it seems for the early too-big-check.

v2: make sure we also exercise the I915_BO_ALLOC_CONTIGUOUS path, which
is quite different, since for that we are actually limited by the
largest power-of-two that we can fit within the region size. (Chris)

drm/vc4: Rework the structure conversion functions
Most of the helpers to retrieve vc4 structures from the DRM base structures
rely on the fact that the first member of the vc4 structure is the DRM one
and just cast the pointers between them.

However, this is pretty fragile especially since there's no check to make
sure that the DRM structure is indeed at the offset 0 in the structure, so
let's use container_of to make it more robust.

They're related to the repacement of some parameters by adev,
and due to a few renamed parameters.

While here, uniform the name of the parameter for it to be
the same on all functions using a pointer to struct amdgpu_device.

Update the kernel-doc documentation accordingly.

f49a51bfdc drm/shme-helpers: Fix dma_buf_mmap forwarding bug
When we forward an mmap to the dma_buf exporter, they get to own
everything. Unfortunately drm_gem_mmap_obj() overwrote
vma->vm_private_data after the driver callback, wreaking the
exporter complete. This was noticed because vb2_common_vm_close blew
up on mali gpu with panfrost after commit 26d3ac3cb0
("drm/shmem-helpers: Redirect mmap for imported dma-buf").

Unfortunately drm_gem_mmap_obj also acquires a surplus reference that
we need to drop in shmem helpers, which is a bit of a mislayer
situation. Maybe the entire dma_buf_mmap forwarding should be pulled
into core gem code.

Note that the only two other drivers which forward mmap in their own
code (etnaviv and exynos) get this somewhat right by overwriting the
gem mmap code. But they seem to still have the leak. This might be a
good excuse to move these drivers over to shmem helpers completely.

drm/vc4: hdmi: Avoid sleeping in atomic context
When running the trigger hook, ALSA by default will take a spinlock, and
thus will run the trigger hook in atomic context.

However, our HDMI driver will send the infoframes as part of the trigger
hook, and part of that process is to wait for a bit to be cleared for up to
100ms. To be nicer to the system, that wait has some usleep_range that
interact poorly with the atomic context.

There's several ways we can fix this, but the more obvious one is to make
ALSA take a mutex instead by setting the nonatomic flag on the DAI link.
That doesn't work though, since now the cyclic callback installed by the
dmaengine helpers in ALSA will take a mutex, while that callback is run by
dmaengine's virt-chan code in a tasklet where sleeping is not allowed
either.

Given the delay we need to poll the bit for, changing the usleep_range for
a udelay and keep running it from a context where interrupts are disabled
is not really a good option either.

However, we can move the infoframe setup code in the hw_params hook, like
is usually done in other HDMI controllers, that isn't protected by a
spinlock and thus where we can sleep. Infoframes will be sent on a regular
basis anyway, and since hw_params is where the audio parameters that end up
in the infoframes are setup, this also makes a bit more sense.

drm/sun4i: frontend: Reuse the ch0 phase for RGB formats
When using the scaler on the A10-like frontend with single-planar formats,
the current code will setup the channel 0 filter (used for the R or Y
component) with a different phase parameter than the channel 1 filter (used
for the G/B or U/V components).

This creates a bleed out that keeps repeating on of the last line of the
RGB plane across the rest of the display. The Allwinner BSP either applies
the same phase parameter over both channels or use a separate one, the
condition being whether the input format is YUV420 or not.

Since YUV420 is both subsampled and multi-planar, and since YUYV is
subsampled but single-planar, we can rule out the subsampling and assume
that the condition is actually whether the format is single or
multi-planar. And it looks like applying the same phase parameter over both
channels for single-planar formats fixes our issue, while we keep the
multi-planar formats working properly.

drm/sun4i: frontend: Rework a bit the phase data
The scaler filter phase setup in the allwinner kernel has two different
cases for setting up the scaler filter, the first one using different phase
parameters for the two channels, and the second one reusing the first
channel parameters on the second channel.

The allwinner kernel has a third option where the horizontal phase of the
second channel will be set to a different value than the vertical one (and
seems like it's the same value than one used on the first channel).
However, that code path seems to never be taken, so we can ignore it for
now, and it's essentially what we're doing so far as well.

Since we will have always the same values across each components of the
filter setup for a given channel, we can simplify a bit our frontend
structure by only storing the phase value we want to apply to a given
channel.

2e368dd2bb ARM: SoC-related driver updates
Various driver updates for platforms. A bulk of this is smaller fixes or
 cleanups, but some of the new material this time around is:
 
  - Support for Nvidia Tegra234 SoC
  - Ring accelerator support for TI AM65x
  - PRUSS driver for TI platforms
  - Renesas support for R-Car V3U SoC
  - Reset support for Cortex-M4 processor on i.MX8MQ
 
 There are also new socinfo entries for a handful of different SoCs
 and platforms.

5c6c13cd11 drm/i915: Drop runtime-pm assert from vgpu io accessors
The "mmio" writes into vgpu registers are simple memory traps from the
guest into the host. We do not need to assert in the guest that the
device is awake for the io as we do not write to the device itself.

However, over time we have refactored all the mmio accessors with the
result that the vgpu reuses the gen2 accessors and so inherits the
assert for runtime-pm of the native device. The assert though has
actually been there since commit 3be0bf5acc ("drm/i915: Create vGPU
specific MMIO operations to reduce traps").

8195400f7e drm/i915: Force VT'd workarounds when running as a guest OS
If i915.ko is being used as a passthrough device, it does not know if
the host is using intel_iommu. Mixing the iommu and gfx causes a few
issues (such as scanout overfetch) which we need to workaround inside
the driver, so if we detect we are running under a hypervisor, also
assume the device access is being virtualised.

3da3c5c1c9 drm/i915: Exclude low pages (128KiB) of stolen from use
The GPU is trashing the low pages of its reserved memory upon reset. If
we are using this memory for ringbuffers, then we will dutiful resubmit
the trashed rings after the reset causing further resets, and worse. We
must exclude this range from our own use. The value of 128KiB was found
by empirical measurement (and verified now with a selftest) on gen9.

4a9bb58aba drm/i915/gt: Wait for CSB entries on Tigerlake
On Tigerlake, we are seeing a repeat of commit d8f5053117 ("drm/i915/icl:
Forcibly evict stale csb entries") where, presumably, due to a missing
Global Observation Point synchronisation, the write pointer of the CSB
ringbuffer is updated _prior_ to the contents of the ringbuffer. That is
we see the GPU report more context-switch entries for us to parse, but
those entries have not been written, leading us to process stale events,
and eventually report a hung GPU.

However, this effect appears to be much more severe than we previously
saw on Icelake (though it might be best if we try the same approach
there as well and measure), and Bruce suggested the good idea of resetting
the CSB entry after use so that we can detect when it has been updated by
the GPU. By instrumenting how long that may be, we can set a reliable
upper bound for how long we should wait for:

    513 late, avg of 61 retries (590 ns), max of 1061 retries (10099 ns)

db9bc2d35f drm/i915: Use the active reference on the vma while capturing
During error capture, we need to take a reference to the vma from before
the reset in order to catpure the contents of the vma later. Currently
we are using both an active reference and a kref, but due to nature of
the i915_vma reference handling, that kref is on the vma->obj and not
the vma itself. This means the vma may be destroyed as soon as it is
idle, that is in between the i915_active_release(&vma->active) and the
i915_vma_put(vma):

64402570e1 drm/i915/gt: Undo forced context restores after trivial preemptions
We may try to preempt the currently executing request, only to find that
after unravelling all the dependencies that the original executing
context is still the earliest in the topological sort and re-submitted
back to HW (if we do detect some change in the ELSP that requires
re-submission). However, due to the way we check for wrap-around during
the unravelling, we mark any context that has been submitted just once
(i.e. with the rq->wa_tail set, but the ring->tail earlier) as
potentially wrapping and requiring a forced restore on resubmission.
This was expected to be not a problem, as it was anticipated that most
unwinding for preemption would result in a context switch and the few
that did not would be lost in the noise. It did not take long for
someone to find one particular workload where the cost of those extra
context restores was measurable.

However, since we know the wa_tail is of fixed size, and we know that a
request must be larger than the wa_tail itself, we can safely maintain
the check for request wrapping and check against a slightly future point
in the ring that includes an expected wa_tail. (That is if the
ring->tail is already set to rq->wa_tail, including another 8 bytes in
the check does not invalidate the incremental wrap detection.)

9b99e5ba3e drm/i915/gt: Delay execlist processing for tgl
When running gem_exec_nop, it floods the system with many requests (with
the goal of userspace submitting faster than the HW can process a single
empty batch). This causes the driver to continually resubmit new
requests onto the end of an active context, a flood of lite-restore
preemptions. If we time this just right, Tigerlake hangs.

Inserting a small delay between the processing of CS events and
submitting the next context, prevents the hang. Naturally it does not
occur with debugging enabled. The suspicion then is that this is related
to the issues with the CS event buffer, and inserting an mmio read of
the CS pointer status appears to be very successful in preventing the
hang. Other registers, or uncached reads, or plain mb, do not prevent
the hang, suggesting that register is key -- but that the hang can be
prevented by a simple udelay, suggests it is just a timing issue like
that encountered by commit 233c1ae3c83f ("drm/i915/gt: Wait for CSB
entries on Tigerlake"). Also note that the hang is not prevented by
applying CTX_DESC_FORCE_RESTORE, or by inserting a delay on the GPU
between requests.

d5e8782129 drm/i915/gem: Support parsing of oversize batches
Matthew Auld noted that on more recent systems (such as the parser for
gen9) we may have objects that are larger than expected by the GEM uAPI
(i.e. greater than u32). These objects would have incorrect implicit
batch lengths, causing the parser to reject them for being incomplete,
or worse.

Based on a patch by Matthew Auld.

1664ffee76 drm/i915: Mark ininitial fb obj as WT on eLLC machines to avoid rcu lockup during fbdev init
Currently we leave the cache_level of the initial fb obj
set to NONE. This means on eLLC machines the first pin_to_display()
will try to switch it to WT which requires a vma unbind+bind.
If that happens during the fbdev initialization rcu does not
seem operational which causes the unbind to get stuck. To
most appearances this looks like a dead machine on boot.

Avoid the unbind by already marking the object cache_level
as WT when creating it. We still do an excplicit ggtt pin
which will rewrite the PTEs anyway, so they will match whatever
cache level we set.

have grown to depend on unused MOCS entries, we are programming
those entries to be equal to fully cached ("L3 + LLC") entry.

These reserved and unspecified entries should not be used as they may be
changed to less performant variants with better coherency in the future
if more entries are needed.

v2: As suggested by Lucas De Marchi to utilise __init_mocs_table for
programming default value, setting I915_MOCS_PTE index of tgl_mocs_table

354842df38 drm/i915/dp: Tweak initial dpcd backlight.enabled value
In commit 7994672309 ("drm/i915: Assume 100% brightness when not in
DPCD control mode"), we fixed the brightness level when DPCD control was
not active to max brightness. This is as good as we can guess since most
backlights go on full when uncontrolled.

However in doing so we changed the semantics of the initial
'backlight.enabled' value. At least on Pixelbooks, they  were relying
on the brightness level in DP_EDP_BACKLIGHT_BRIGHTNESS_MSB to be 0 on
boot such that enabled would be false. This causes the device to be
enabled when the brightness is set. Without this, brightness control
doesn't work. So by changing brightness to max, we also flipped enabled
to be true on boot.

To fix this, make enabled a function of brightness and backlight control
mechanism.

If guest fills non-priv bb on ApolloLake/Broxton as Mesa i965 does in:
717e7539124d (i965: Use a WC map and memcpy for the batch instead of pw-)
Due to the missing flush of bb filled by VM vCPU, host GPU hangs on
executing these MI_BATCH_BUFFER.

Temporarily workaround this by setting SNOOP bit for PAT3 used by PPGTT
PML4 PTE: PAT(0) PCD(1) PWT(1).

The performance is still expected to be low, will need further improvement.

97f9ca383d drm/i915/gvt: Allow zero out HWSP addr on hws_pga_write
Guest driver may reset HWSP to 0 as init value during D3->D0:
The full sequence is:
 - Boot ->D0
 - Update HWSP
 - D0->D3
 - ...In D3 state...
 - D3->D0
 - DMLR reset.
 - Set engine HWSP to 0.
 - Set engine ring mode to 0.
 - Set engine HWSP to correct value.
 - Set engine ring mode to correct value.
Ring mode is masked register so set 0 won't take effect.
However HWPS addr 0 is considered as invalid GGTT address which will
report error like:
       gvt: vgpu 1: write invalid HWSP address, reg:0x2080, value:0x0
       gvt: vgpu 1: fail to emulate MMIO write 00002080 len 4
       Detected your guest driver doesn't support GVT-g.
       Now vgpu 2 will enter failsafe mode.

Zero out HWSP addr is considered as a valid setting from device driver
so don't treat it as invalid HWSP addr.

V2:
Treat HWSP addr 0 as valid. (zhenyu)

V3:
Change patch title.

i915_gem_object_map implements fairly low-level vmap functionality in a

The only practical difference is that alloc_vm_area prefeaults the vmalloc
area PTEs, which doesn't seem to be required here for the kernel memory
case (and could be added to vmap using a flag if actually required).

44264591a8 drm/amd/display: Fix module load hangs when connected to an eDP
It was recently introduced a change that enables driver to disable
streams if pixel clock changes. Consequently, the code path executed in
the disable vbios function expanded to an encoder verification part.
The encoder loop is nested inside the pipe count loop, and both loops
share the 'i' variable in control of their flow. This situation may lead
to an infinite loop because the encoder loop constantly updates the `i`
variable, making the first loop always positive. As a result, we can see
a soft hang during the module load (modprobe amdgpu) and a series of
dmesg log that looks like this:

In support of device-dax growing the ability to front physically
dis-contiguous ranges of memory, update devm_memremap_pages() to track
multiple ranges with a single reference counter and devm instance.

Convert all [devm_]memremap_pages() users to specify the number of ranges
they are mapping in their 'struct dev_pagemap' instance.

a4574f63ed mm/memremap_pages: convert to 'struct range'
The 'struct resource' in 'struct dev_pagemap' is only used for holding
resource span information.  The other fields, 'name', 'flags', 'desc',
'parent', 'sibling', and 'child' are all unused wasted space.

This is in preparation for introducing a multi-range extension of
devm_memremap_pages().

The bulk of this change is unwinding all the places internal to libnvdimm
that used 'struct resource' unnecessarily, and replacing instances of
'struct dev_pagemap'.res with 'struct dev_pagemap'.range.

P2PDMA had a minor usage of the resource flags field, but only to report
failures with "%pR".  That is replaced with an open coded print of the
range.

214bba5061 drm/i915: Set all unused color plane offsets to ~0xfff again
When the number of potential color planes grew to 4 we stopped
setting all unused color plane offsets to ~0xfff. The code
still tries to do this, but actually does nothing since the
loop limits are bogus.

skl_check_main_surface() actually depends on this ~0xfff
behaviour as it will make sure to move the main surface
offset below the aux surface offset because the hardware
AUX_DIST must be a non-negative value [1], and for simplicity
it doesn't bother checking if the AUX plane is actually
needed or not. So currently it may end up shuffling the
main surface around based on some stale leftover AUX offset.

The skl+ plane code also just blindly calculates the AUX_DIST
whether or not the AUX plane is actually needed by the hw or
not, and that too will now potentially use some stale AUX
surface offset in the calculation. Would seem nicer to
guarantee a consistent non-negative AUX_DIST always.

So bring back the original ~0xfff offset behaviour for
unused color planes. Though it doesn't seem super likely
that this inconsistency would cause any real issues.

f0b707c125 drm/i915: Fix TGL DKL PHY DP vswing handling
The HDMI vs. not-HDMI check got inverted whem the bogus encoder->type
checks were eliminated. So now we're using 0 as the link rate on DP
and potentially non-zero on HDMI, which is exactly the opposite of
what we want. The original bogus check actually worked more correctly
by accident since if would always evaluate to true. Due to this we
now always use the RBR/HBR1 vswing table and never ever the HBR2+
vswing table. That is probably not a good way to get a high quality
signal at HBR2+ rates. Fix the check so we pick the right table.

As the dpm clock table is needed during DC HW initialization.
And that (DC HW initialization) comes before smu_late_init()

pointer dereference will be triggered. By moving APU dpm clock

c2df75ad2a drm/panfrost: increase readl_relaxed_poll_timeout values
Amlogic SoC devices report the following errors frequently causing excessive
dmesg log spam and early log rotataion, although the errors appear to be
harmless as everything works fine:

[    7.203760] panfrost ffe40000.gpu: error powering up gpu shader

ARM staff have advised increasing the timeout values to eliminate the errors
in most normal scenarios, and testing with several different G31/G52 devices
shows 20000 to be a reliable value.

07da1223ec lib/scatterlist: Add support in dynamic allocation of SG table from pages
Extend __sg_alloc_table_from_pages to support dynamic allocation of
SG table from pages. It should be used by drivers that can't supply
all the pages at one time.

This function returns the last populated SGE in the table. Users should
pass it as an argument to the function from the second call and forward.
As before, nents will be equal to the number of populated SGEs (chunks).

With this new extension, drivers can benefit the optimization of merging
contiguous pages without a need to allocate all pages in advance and
hold them in a large buffer.

E.g. with the Infiniband driver that allocates a single page for hold the
pages. For 1TB memory registration, the temporary buffer would consume only
4KB, instead of 2GB.

95d620adb4 drm/amd/display: HDMI remote sink need mode validation for Linux
[Why]
Currently mode validation is bypassed if remote sink exists. That
leads to mode set issue when a BW bottle neck exists in the link path,
e.g., a DP-to-HDMI converter that only supports HDMI 1.4.

Any invalid mode passed to Linux user space will cause the modeset
failure due to limitation of Linux user space implementation.

[How]
Mode validation is skipped only if in edid override. For real remote
sink, clock limit check should be done for HDMI remote sink.

Have HDMI related remote sink going through mode validation to
elimiate modes which pixel clock exceeds BW limitation.

2f8be0e516 drm/amd/display: Avoid set zero in the requested clk
[Why]
Sometimes CRTCs can be disabled due to display unplugging or temporarily
transition in the userspace; in these circumstances, DCE tries to set
the minimum clock threshold. When we have this situation, the function
bw_calcs is invoked with number_of_displays set to zero, making DCE set
dispclk_khz and sclk_khz to zero. For these reasons, we have seen some
ATOM bios errors that look like:

[drm:atom_op_jump [amdgpu]] *ERROR* atombios stuck in loop for more than
5secs aborting
[drm:amdgpu_atom_execute_table_locked [amdgpu]] *ERROR* atombios stuck
executing EA8A (len 761, WS 0, PS 0) @ 0xEABA

[How]
This error happens due to an attempt to optimize the bandwidth using the
sclk, and the dispclk clock set to zero. Technically we handle this in
the function dce112_set_clock, but we are not considering the case that
this value is set to zero. This commit fixes this issue by ensuring that
we never set a minimum value below the minimum clock threshold.

Commit c1cf79ca5c ("drm/amdgpu: use IP discovery table for renoir")
introduced a NULL pointer dereference when booting with
amdgpu.discovery=0, because it removed the call of vega10_reg_base_init()

Fix this by calling that funcion if amdgpu_discovery == 0 in addition to
the case that amdgpu_discovery_reg_base_init() failed.

Currently, we check we can send a pulse prior to disabling the
heartbeat to verify that we can change the heartbeat, but since we may
re-evaluate execution upon changing the heartbeat interval we need another
pulse afterwards to refresh execution.

v2: Tvrtko asked if we could reduce the double pulse to a single, which
opened up a discussion of how we should handle the pulse-error after
attempting to change the property, and the desire to serialise
adjustment of the property with its validating pulse, and unwind upon
failure.

We only allow persistent requests to remain on the GPU past the closure
of their containing context (and process) so long as they are continuously
checked for hangs or allow other requests to preempt them, as we need to
ensure forward progress of the system. If we allow persistent contexts
to remain on the system after the the hangcheck mechanism is disabled,
the system may grind to a halt. On disabling the mechanism, we sent a
pulse along the engine to remove all executing contexts from the engine
which would check for hung contexts -- but we did not prevent those
contexts from being resubmitted if they survived the final hangcheck.

3cfea8c97c drm/i915/gem: Hold request reference for canceling an active context
We have to be very careful while walking the timeline->requests list
under the RCU guard, as the requests (and so rq->link) use
SLAB_TYPESAFE_BY_RCU and so the requests may be reallocated within an
rcu grace period. As the requests are reallocated, they are removed from
one list and placed on another, and if we are iterating over that
request at that moment, the list iteration jumps from one list to the
next and promptly gets confused. Verify we hold the request reference
to ensure that the request is not added to a new list behind our backs.

4fe9af8e88 drm/i915/gem: Serialise debugfs i915_gem_objects with ctx->mutex
Since the debugfs may peek into the GEM contexts as the corresponding
client/fd is being closed, we may try and follow a dangling pointer.
However, the context closure itself is serialised with the ctx->mutex,
so if we hold that mutex as we inspect the state coupled in the context,
we know the pointers within the context are stable and will remain valid
as we inspect their tables.

the current jiffy as its node->age. There is then a miniscule window,
where as that node is retired, it will appear on the free list with an
incorrect age and be eligible for reuse by one thread, and then by a
second thread as the correct node->age is written.

4caf017ee9 drm/i915/gem: Avoid implicit vmap for highmem on x86-32
On 32b, highmem using a finite set of indirect PTE (i.e. vmap) to provide
virtual mappings of the high pages.  As these are finite, map_new_virtual()
must wait for some other kmap() to finish when it runs out. If we map a
large number of objects, there is no method for it to tell us to release
the mappings, and we deadlock.

However, if we make an explicit vmap of the page, that uses a larger
vmalloc arena, and also has the ability to tell us to release unwanted
mappings. Most importantly, it will fail and propagate an error instead
of waiting forever.

allowing -ENOSPC to be returned. That seems to fix recent
regressions with vmwgfx.

a39d0d7bdf drm/amdgpu: restore proper ref count in amdgpu_display_crtc_set_config
A recent attempt to fix a ref count leak in
amdgpu_display_crtc_set_config() turned out to be doing too much and
"fixed" an intended decrease as if it were a leak. Undo that part to
restore the proper balance. This is the very nature of this function
to increase or decrease the power reference count depending on the
situation.

Consequences of this bug is that the power reference would
eventually get down to 0 while the display was still in use,
resulting in that display switching off unexpectedly.

12a6727dee drm/amd/powerplay: add one sysfs file to support the feature to modify gfx clock on Raven/Raven2/Picasso APU.
This patch is to add one sysfs file -- "pp_od_clk_voltage" for
Raven/Raven2/Picasso APU, which is only used by dGPU like VEGA10.
This sysfs file supports the feature to modify gfx engine clock(Mhz units), it can
be used to configure the min value and the max value for gfx clock limited in the
safe range.

Command guide:
echo "s level clock" > pp_od_clk_voltage
	s - adjust teh sclk level
	level - 0 or 1, "0" represents the min value, "1" represents the max value
	clock - the clock value(Mhz units), like 400, 800 or 1200, the value must be within the
                OD_RANGE limits.
Example:
$ cat pp_od_clk_voltage
OD_SCLK:
0:        200Mhz
1:       1400Mhz
OD_RANGE:
SCLK:     200MHz       1400MHz

$ echo "s 0 600" > pp_od_clk_voltage
$ echo "s 1 1000" > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0:        600Mhz
1:       1000Mhz
OD_RANGE:
SCLK:     200MHz       1400MHz

72e71a82d6 drm/amdgpu: add new trace event for page table update
This patch adds a new trace event to track the PTE update
events. This specific event will provide information like:
- start and end of virtual memory mapping
- HW engine flags for the map
- physical address for mapping

This will be particularly useful for memory profiling tools
(like RMV) which are monitoring the page table update events.

V2: Added physical address lookup logic in trace point
V3: switch to use __dynamic_array
    added nptes int the TPprint arguments list
    added page size in the arg list
V4: Addressed Christian's review comments
    add start/end instead of seg
    use incr instead of page_sz to be accurate
V5: Addressed Christian's review comments:
    add pid and vm context information in the event

8e02c26a58 drm/amd/display: Calc DLG from dummy p-state if full p-state unsupported
[Why]
Currently, when full p-state changes are not supported, DLG parameters
are calculated for no p-state support at all. However, we are required
to always support dummy p-state changes, so we should instead calculate
DLG based on dummy p-state latency when full p-state is unsupported.
This behaviour already exists for DCN2.

[How]
 - move DLG calculation inside WM calculation
 - if p-state unsupported, do not recalculate for set A, instead copy from
set C, and perform DLG calculation with dummy p-state latency

ef80c1a1d2 drm/i915: Fix state checker hw.active/hw.enable readout
Previously intel_dump_pipe_config() used to dump the full crtc state
whether or not the crtc was logically enabled or not. As that meant
occasionally dumping confusing stale garbage I changed it to
check whether the crtc is logically enabled or not. However I did
not realize that the state checker readout code does not
populate crtc_state.hw.{active,enabled}. Hence the state checker
dump would only give us a full dump of the sw state but not the hw
state. Fix that by populating those bits of the hw state as well.

- Refactor the driver code to use amdgpu_virt_read_pf2vf_data
  and amdgpu_virt_write_vf2pf_data instead of writing all code in
  one function (which is the old amdgpu_virt_init_data_exchange)

- Adding a new transaction method for VF2PF message between host
  and guest driver. Guest side will periodically update VF2PF
  message in the framebuffer.

  In the new header, we include guest ucode information, guest
  framebuffer usage, and engine usage

- Clean up the old macros since they will cause compile error if
  the new transaction method is used

drm/vc4: crtc: Keep the previously assigned HVS FIFO
The HVS FIFOs are currently assigned each time we have an atomic_check
for all the enabled CRTCs.

However, if we are running multiple outputs in parallel and we happen to
disable the first (by index) CRTC, we end up changing the assigned FIFO
of the second CRTC without disabling and reenabling the pixelvalve which
ends up in a stall and eventually a VBLANK timeout.

In order to fix this, we can create a special value for our assigned
channel to mark it as disabled, and if our CRTC already had an assigned
channel in its previous state, we keep on using it.

drm/vc4: crtc: Rework a bit the CRTC state code
The current CRTC state reset hook in vc4 allocates a vc4_crtc_state
structure as a drm_crtc_state, and relies on the fact that vc4_crtc_state
embeds drm_crtc_state as its first member, and therefore can be safely
cast.

However, this is pretty fragile especially since there's no check for this
in place, and we're going to need to access vc4_crtc_state member at reset
so this looks like a good occasion to make it more robust.
