edb1ed1ab7 drm/dp: Add DP MST helpers to atomically find and release vcpi slots
drm_dp_atomic_find_vcpi_slots() should be called from ->atomic_check() to
check there are sufficient vcpi slots for a mode and to add that to the
state. This should be followed by a call to drm_dp_mst_allocate_vcpi()
in ->atomic_commit() to initialize a struct vcpi for the port.

drm_dp_atomic_release_vcpi_slots() should be called from
->atomic_check() to release a port's vcpi slot allocation from the
state.

Drivers that do not make use of this atomic helper are expected to call
drm_dp_find_vcpi_slots() instead before calling
drm_dp_mst_allocate_vcpi().

v3: drm_dp_atomic_release_vcpi_slots() now needs to know how many slots
    to release as we may not have a valid reference to port.
v2:
Added checks for verifying the port reference is valid
Moved get_mst_topology_state() into the helpers (Daniel)
Changed find_vcpi_slots() to not depend on current allocation

3f3353b7e1 drm/dp: Introduce MST topology state to track available link bandwidth
Link bandwidth is shared between multiple display streams in DP MST
configurations. The DP MST topology manager structure maintains the
shared link bandwidth for a primary link directly connected to the GPU. For
atomic modesetting drivers, checking if there is sufficient link bandwidth
for a mode needs to be done during the atomic_check phase to avoid failed
modesets. Let's encapsulate the available link bw information in a
private state structure so that bw can be allocated and released atomically
for each of the ports sharing the primary link.

v3: WARN_ON() if connection_mutex is not held (Archit)
v2: Included kernel doc, moved state initialization and switched to
kmemdup() for allocation (Daniel)

b430c27a7d drm: Add driver-private objects to atomic state
It is necessary to track states for objects other than connector, crtc
and plane for atomic modesets. But adding objects like DP MST link
bandwidth to drm_atomic_state would mean that a non-core object will be
modified by the core helper functions for swapping and clearing
it's state. So, lets add void * objects and helper functions that operate
on void * types to keep these objects and states private to the core.
Drivers can then implement specific functions to swap and clear states.
The other advantage having just void * for these objects in
drm_atomic_state is that objects of different types can be managed in the
same state array.

v7: Use __for_each_private_obj to define for_each_private_obj (Maarten)
v6: More kernel-doc to keep 0-day happy
v5: Remove more NULL checks (Maarten)
v4: Avoid redundant NULL checks when private_objs array is empty (Maarten)
v3: Macro alignment (Chris)
v2: Added docs and new iterator to filter private objects (Daniel)

98da65d5e3 Revert "drm/amdgpu: Refactor flip into prepare submit and submit. (v3)"
This reverts commit cb341a319f.

The purpose of the refactor was for amdgpu_crtc_prepare/submit_flip to
be used by the DC code, but that's no longer the case.

A missing u64 cast causes a 32-Bit wraparound from
4096 MiB to 0 MiB and therefore total 0 MiB VRAM detected
if card has 4096 Mib per FBP.

60b95d7095 drm/nouveau/kms: Increase max retries in scanout position queries.
So far we only allowed for 1 retry and just failed the query
- and thereby high precision vblank timestamping - if we did
not get a reasonable result, as such a failure wasn't considered
all too horrible. There are a few NVidia gpu models out there which
may need a bit more than 1 retry to get a successful query result
under some conditions.

Since Linux 4.4 the update code for vblank counter and timestamp
in drm_update_vblank_count() changed so that the implementation
assumes that high precision vblank timestamping of a kms driver
either consistently succeeds or consistently fails for a given
video mode and encoder/connector combo. Iow. switching from success
to fail or vice versa on a modeset or connector change is ok, but
spurious temporary failure for a given setup can confuse the core
code and potentially cause bad miscounting of vblanks and confusion
or hangs in userspace clients which rely on vblank  stuff, e.g.,
desktop compositors.

Therefore change the max retry count to a larger number - more than
any gpu so far is known to need to succeed, but still low enough
so that these queries which do also happen in vblank interrupt are
still fast enough to be not disastrously long if something would
go badly wrong with them.

As such sporadic retries only happen seldom even on affected gpu's,
this could mean a vblank irq could take a few dozen microseconds
longer every few hours of uptime -- better than a desktop compositor
randomly hanging every couple of hours or days of uptime in a hard
to reproduce manner.

value should be validated. However, in functions r420_cp_errata_init()
and r420_cp_errata_fini(), its return value is not checked. This patch
adds the checks.

Fix issue that PSP initialization will fail if reload amdgpu module.
That's because the PSP ring must be destroyed to be ready for the
next time PSP initialization.

Changes in v2:
	- Move psp_ring_destroy before all BOs free (suggested by
	  Ray Huang).
Changes in v3:
	- Check firmware load type, if it is not PSP, we should do
	  nothing in fw_fini(), and of course will not destroy
	  PSP ring too (suggested by Ray Huang).

ee73164a0d drm/amdgpu/virt: don't check VALID bit for FLR completion message
The interrupt after FLR is missed sometimes due to hardware reason, so
guest driver get the notification of FLR completion via polling
message. Then host doesn't write VALID bit to avoid sending interrupt,
otherwise the completion will be handled twice.

So there's a valid message without VALID bit for FLR completion,
driver should handle it without checking.

459b086d87 drm/rockchip: Set line flag config register in vop_crtc_enable
We need to set vop config done after update line flag config, it's a
new requirement for chips newer than rk3368.

Since we would only use line flag irq for vact_end, let's move it to
vop_crtc_enable.

763656d30b drm: mali-dp: use div_u64 for expensive 64-bit divisions
On 32-bit machines, we can't divide 64-bit integers:

drivers/gpu/drm/arm/malidp_crtc.o: In function `malidp_crtc_atomic_check':
malidp_crtc.c:(.text.malidp_crtc_atomic_check+0x3c0): undefined reference to `__aeabi_uldivmod'
malidp_crtc.c:(.text.malidp_crtc_atomic_check+0x3dc): undefined reference to `__aeabi_uldivmod'

This calls the div_u64 function explicitly instead.

88326ef05b drm/i915: Confirm the request is still active before adding it to the await
Although we do check the completion-status of the request before
actually adding a wait on it (either to its submit fence or its
completion dma-fence), we currently do not check before adding it to the
dependency lists.

In fact, without checking for a completed request we may try to use the
signaler after it has been retired and its dependency tree freed:

Note to hit the use-after-free requires us to be passed back a request
via a fence-array, that is from explicit fencing accumulated into a
sync-file fence-array.

acf2dc2266 drm/i915: Fix system hang with EI UP masked on Haswell
Previously with commit a9c1f90c8e
("drm/i915: Don't mask EI UP interrupt on IVB|SNB") certain,
seemingly unrelated bit (GEN6_PM_RP_UP_EI_EXPIRED) was needed
to be unmasked for IVB and SNB in order to prevent system hang
with chained batchbuffers.

Our CI was seeing incomplete results with tests that used
chained batches and it was found out that HSW needs to have this
same bit unmasked to reliably survive chained batches.

Always unmask GEN6_PM_RP_UP_EI_EXPIRED on Haswell to
prevent system hang with batch chaining.

dea6559398 drm/i915: Perform link quality check unconditionally during long pulse
Apparently some DP sinks are a little nuts and cause HPD to drop
intermittently during modesets. This happens eg. on an ASUS PB287Q.
In oder to recover from this we can't really use the previous
connector status to determine if the link needs retraining, so let's
just ignore that piece of information and do the retrain
unconditionally. We do of course still check whether the link is
supposed to be running or not.

To actually get read out the EDID and update things properly we
also need to nuke the goto out added by commit 7d23e3c37b
("drm/i915: Cleaning up intel_dp_hpd_pulse"). I'm actually not sure
why that was there. Perhaps to avoid an EDID read if the connector
status didn't appear to change, but that sort of thing is quite racy
and would have failed anyway if we failed to keep up with the
hotplugs (if we missed the HPD down in between two HPD ups). And
now that we take this codepath unconditionally we definitely need
to drop the goto as otherwise we would never do the EDID read.

v2: Drop the goto that made us skip EDID reads entirely. Doh!
v3: Rebase due to locking changes

bdb57b8dca drm/i915: Use the right mapping_gfp_mask for final shmem allocation
Many sightings report the greater prevalence of allocation failures.
This is all due to the incorrect use of mapping_gfp_constraint(), so
remove it in favour of just querying the mapping_gfp_mask() which are
the exact gfp_t we wanted in the first place.

We still do expect a higher chance of reporting ENOMEM, as that is the
intention of using __GFP_NORETRY -- to fail rather than oom after having
reclaimed from our bo caches, and having done a direct|kswapd reclaim
pass.

d445aaaac0 drm/i915: Apply a cond_resched() to the saturated signaler
If the engine is continually completing nops, we can saturate the
signaler and keep it working indefinitely. This angers the NMI watchdog!

A good example is to disable semaphores on snb and run igt/gem_exec_nop -
the parallel, multi-engine workloads are more than sufficient to hog the
CPU, preventing the system from even processing ICMP echo replies.

v2: Tvrtko dug into cond_resched() on x86 and found that it only
depended upon preempt_count and not tif_need_resched() - which means
that we would always call schedule() at that point.

order to be able to fetch the higher-resolution data and produce output

pxlclk. Since the driver doesn't control mclk, just ensure that the

7a9d2001a1 drm/vmwgfx: Convert macro to octal representation
Change "S_IRUSR | S_IWUSR" to "0600", it's easier to parse mentally.

This change should be part of commit 50f837371d ("drm/vmwgfx: Revert
"drm/vmwgfx: Replace numeric parameter like 0444 with macro""), but the
patch was truncated somewhere in the patch route, so add the missing

    This reverts commit 2d8e60e8b0 ("drm/vmwgfx: Replace numeric

    The commit belongs to the series of 1285 patches sent to LKML on
    2016-08-02, it changes the representation of file permissions from
    the octal value "0600" to "S_IRUSR | S_IWUSR".

    The general consensus was that the changes does not increase

57fbc05585 drm: dw-hdmi: gate audio clock from the I2S enablement callbacks
Currently, the audio sampler clock is enabled from dw_hdmi_setup() at
step E. and is kept enabled for later use. This clock should be enabled
and disabled along with the actual audio stream and not always on (that
is bad for PM). Furthermore, as described by the datasheet, the I2S
variant needs to gate/ungate the clock when the stream is
enabled/disabled.

This commit adds a parameter to hdmi_audio_enable_clk() that controls
when the audio sample clock must be enabled or disabled. Then, it adds
the call to this function from dw_hdmi_i2s_audio_enable() and
dw_hdmi_i2s_audio_disable().

a7d555d2f2 drm: dw-hdmi: add specific I2S and AHB functions for stream handling
Currently, CTS+N is forced to zero as a workaround of the IP block for
i.MX platforms. This is requested in the datasheet of the corresponding
IP for AHB mode only. However, we have seen that it introduces glitches
or delays when playing a sound on HDMI for I2S mode. This proves that we
cannot keep the current functions for handling audio stream as-is if
these contain workaround that are specific to a mode.

This commit introduces two callbacks, one for each variant.
dw_hdmi_setup defines the right function depending on the detected
variant. Then, the exported functions dw_hdmi_audio_enable and
dw_hdmi_audio_disable calls the corresponding callbacks

f9b67f0014 dma-buf: Rename dma-ops to prevent conflict with kunmap_atomic macro
Seeing the kunmap_atomic dma_buf_ops share the same name with a macro
in highmem.h, the former can be aliased if any dma-buf user includes
that header.

I'm personally trying to include highmem.h inside scatterlist.h and this
breaks the dma-buf code proper.

Christoph Hellwig suggested [1] renaming it and pushing this patch ASAP.

To maintain consistency I've renamed all four of kmap* and kunmap* to be
map* and unmap*. (Even though only kmap_atomic presently conflicts.)

553c942f8b drm/vc4: Allow using more than 256MB of CMA memory.
Until now, we've had to limit Raspberry Pi to 256MB of CMA memory to
keep from triggering the hardware addressing bug between the tile
binner and the tile alloc memory (where the top 4 bits come from the
tile state data array's address).

To work around that and allow more memory to be reserved for graphics,
allocate a single BO to store tile state data arrays and tile
alloc/overflow memory while the GPU is active, and make sure that that
one BO doesn't happen to cross a 256MB boundary.  With that in place,
we can allocate textures and shaders anywhere in system memory (still
contiguous, of course).

Move all activation code to vc4_hdmi_encoder_enable() and make sure

by adding deactivation steps in vc4_hdmi_encoder_disable().

Note that the sequencing imposed by the IP requires that we move

5f0d5a3ae7 mm: Rename SLAB_DESTROY_BY_RCU to SLAB_TYPESAFE_BY_RCU
A group of Linux kernel hackers reported chasing a bug that resulted
from their assumption that SLAB_DESTROY_BY_RCU provided an existence
guarantee, that is, that no block from such a slab would be reallocated
during an RCU read-side critical section.  Of course, that is not the
case.  Instead, SLAB_DESTROY_BY_RCU only prevents freeing of an entire
slab of blocks.

However, there is a phrase for this, namely "type safety".  This commit
therefore renames SLAB_DESTROY_BY_RCU to SLAB_TYPESAFE_BY_RCU in order
to avoid future instances of this sort of confusion.

765393db20 drm/cma-helper: Return ENOENT for "no such gem obj"
All the error codes we (ab)use are strictly not the right ones (since
they're all for the vfs, and the only thing we're allowed to do from
an ioctl is EINVAL). But ENOENT is the common error code for failed to
look up an object throughout drm, so let's use it in the cma helpers,
too.

Note that this does change uabi for some drivers, but that shouldn't
ba a problem:
- other drivers (e.g. i915) already return ENOENT for invalid gem bo
- userspace tends to only check for errors, not specific ones (except
  when ioctl restarting is needed)
- if the gem bo isn't there a previous step (either creating or
  importing it) failed already, this situation should always be a
  userspace bug.

Changing it does help with debugging userspace bugs though, by making
error reporting more consistent.

c053b5a506 drm/i915: Don't call synchronize_rcu_expedited under struct_mutex
Only call synchronize_rcu_expedited after unlocking struct_mutex to
avoid deadlock because the workqueues depend on struct_mutex.

>From original patch by Andrea:

synchronize_rcu/synchronize_sched/synchronize_rcu_expedited() will
hang until its own workqueues are run. The i915 gem workqueues will
wait on the struct_mutex to be released. So we cannot wait for a
quiescent state using those rcu primitives while holding the
struct_mutex or it creates a circular lock dependency resulting in
kernel hangs (which is reproducible but goes undetected by lockdep).

63987bfebd drm/i915: Suspend GuC prior to GPU Reset during GEM suspend
i915 is currently doing a full GPU reset at the end of
i915_gem_suspend() followed by GuC suspend in i915_drm_suspend(). This
GPU reset clobbers the GuC, causing the suspend request to then fail,
leaving the GuC in an undefined state. We need to tell the GuC to
suspend before we do the direct intel_gpu_reset().

v2: Commit message update. (Chris, Daniele)
