commit 3b82a4db8eaccce735dffd50b4d4e1578099b8e8 upstream.
The memmap options sent to the udl framebuffer driver were not being
checked for all sets of possible crazy values. Fix this up by properly
bounding the allowed values.

commit 2681bc79eeb640562c932007bfebbbdc55bf6a7d upstream.
Turning off the sink in this case causes various issues, because
userspace expects it to stay on until it turns it off explicitly.
Instead, turn the sink off and back on when a display is connected
again. This dance seems necessary for link training to work correctly.

commit 73a88250b70954a8f27c2444e1c2411bba3c29d9 upstream.
When validating legacy surfaces, the backup bo might be destroyed at
surface validate time. However, the kms resource validation code may have
the bo reserved, so we will destroy a locked mutex. While there shouldn't
be any other users of that mutex when it is destroyed, it causes a lock
leak and thus throws a lockdep error.
Fix this by having the kms resource validation code hold a reference to
the bo while we have it reserved. We do this by introducing a validation
context which might come in handy when the kms code is extended to validate
multiple resources or buffers.

[ Upstream commit b7ea6b286c4051e043f691781785e3c4672f014a ]
Check the status of the DMM engine after it is reported that the
transaction was completed as in rare cases the engine might not reached a
working state.
The wait_status() will print information in case the DMM is not reached the
expected state and the dmm_txn_commit() will return with an error code to
make sure that we are not continuing with a broken setup.

[ Upstream commit 62e3a3e342af3c313ab38603811ecdb1fcc79edb ]
get_pages doesn't keep a reference of the pages allocated
when it fails later in the code path. This can lead to
a memory leak. Keep reference of the allocated pages so
that it can be freed when msm_gem_free_object gets called
later during cleanup.

[ Upstream commit 60b95d709525e3ce1c51e1fc93175dcd1755d345 ]
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.

commit 7d617264eb22b18d979eac6e85877a141253034e upstream.
Turning off the sink in this case causes various issues, because
userspace expects it to stay on until it turns it off explicitly.
Instead, turn the sink off and back on when a display is connected
again. This dance seems necessary for link training to work correctly.

[ Upstream commit 5108d768408abc80e4e8d99f5b406a73cb04056b ]
Kobject created using kobject_create_and_add() can be freed using
kobject_put() when there is no referenece any more. However,
kobject memory allocated with kzalloc() has to set up a release
callback in order to free it when the counter decreases to 0.
Otherwise it causes memory leak.

[ Upstream commit 1d1c36650752b7fb81cee515a9bba4131cac4b7c ]
Since drm_edid_to_eld() knows the connector type, we can set the type in
ELD while at it. Most connectors this gets called on are not DP
encoders, and with the HDMI type being 0, this does not change behaviour
for non-DP.
For i915 having this in place earlier would have saved a considerable
amount of debugging that lead to the fix 2d8f63297b9f ("drm/i915: always
update ELD connector type after get modes"). I don't see other drivers,
even the ones calling drm_edid_to_eld() on DP connectors, setting the
connector type in ELD.

[ Upstream commit 608b20506941969ea30d8c08dc9ae02bb87dbf7d ]
On vblank instant-off systems, we can get into a situation where the cost
of enabling and disabling the vblank IRQ around a drmWaitVblank query
dominates. And with the advent of even deeper hardware sleep state,
touching registers becomes ever more expensive. However, we know that if
the user wants the current vblank counter, they are also very likely to
immediately queue a vblank wait and so we can keep the interrupt around
and only turn it off if we have no further vblank requests queued within
the interrupt interval.
After vblank event delivery, this patch adds a shadow of one vblank where
the interrupt is kept alive for the user to query and queue another vblank
event. Similarly, if the user is using blocking drmWaitVblanks, the
interrupt will be disabled on the IRQ following the wait completion.
However, if the user is simply querying the current vblank counter and
timestamp, the interrupt will be disabled after every IRQ and the user
will enabled it again on the first query following the IRQ.
v2: Mario Kleiner -
After testing this, one more thing that would make sense is to move
the disable block at the end of drm_handle_vblank() instead of at the
top.
Turns out that if high precision timestaming is disabled or doesn't
work for some reason (as can be simulated by echo 0 >
/sys/module/drm/parameters/timestamp_precision_usec), then with your
delayed disable code at its current place, the vblank counter won't
increment anymore at all for instant queries, ie. with your other
"instant query" patches. Clients which repeatedly query the counter
and wait for it to progress will simply hang, spinning in an endless
query loop. There's that comment in vblank_disable_and_save:
"* Skip this step if there isn't any high precision timestamp
* available. In that case we can't account for this and just
* hope for the best.
*/
With the disable happening after leading edge of vblank (== hw counter
increment already happened) but before the vblank counter/timestamp
handling in drm_handle_vblank, that step is needed to keep the counter
progressing, so skipping it is bad.
Now without high precision timestamping support, a kms driver must not
set dev->vblank_disable_immediate = true, as this would cause problems
for clients, so this shouldn't matter, but it would be good to still
make this robust against a future kms driver which might have
unreliable high precision timestamping, e.g., high precision
timestamping that intermittently doesn't work.
v3: Patch before coffee needs extra coffee.

[ Upstream commit 861078381ba56b56808113736000d9e7ead349c8 ]
If fbdev emulation is disabled, the QXL shutdown path will try to clean
a framebuffer that wasn't initialized, hitting the Oops below. The
problem is that even when FBDEV_EMULATION is disabled we allocate the
qfbdev strutucture, but we don't initialize it. The fix is to stop
allocating the memory, since it won't be used. This allows the existing
verification in the cleanup hook to do it's job preventing the oops.
Now that we don't allocate the unused fbdev structure, we need to be
careful when dereferencing it in the PM suspend hook.

commit aa0aad57909eb321746325951d66af88a83bc956 upstream.
amdgpu's ->runtime_suspend hook calls drm_kms_helper_poll_disable(),
which waits for the output poll worker to finish if it's running.
The output poll worker meanwhile calls pm_runtime_get_sync() in
amdgpu's ->detect hooks, which waits for the ongoing suspend to finish,
causing a deadlock.
Fix by not acquiring a runtime PM ref if the ->detect hooks are called
in the output poll worker's context. This is safe because the poll
worker is only enabled while runtime active and we know that
->runtime_suspend waits for it to finish.

commit 25c058ccaf2ebbc3e250ec1e199e161f91fe27d4 upstream.
Introduce a helper to determine if the current task is an output poll
worker.
This allows us to fix a long-standing deadlock in several DRM drivers
wherein the ->runtime_suspend callback waits for the output poll worker
to finish and the worker in turn calls a ->detect callback which waits
for runtime suspend to finish. The ->detect callback is invoked from
multiple call sites and waiting for runtime suspend to finish is the
correct thing to do except if it's executing in the context of the
worker.
v2: Expand kerneldoc to specifically mention deadlock between
output poll worker and autosuspend worker as use case. (Lyude)

Doing a rearm once before getting any interrupts fixes this.

commit 458d876eb869d5a88b53074c6c271b8b9adc0f07 upstream.
We only support vga_switcheroo and runtime pm on PX/HG systems
so forcing runpm to 1 doesn't do anything useful anyway.
Only call vga_switcheroo_init_domain_pm_ops() for PX/HG so
that the cleanup path is correct as well. This mirrors what
radeon does as well.
v2: rework the patch originally sent by Lukas (Alex)

Similar to commit e10aec652f31 ("drm/edid: Add 6 bpc quirk for display

6bpc instead of 8 bpc.

commit db9b60400f9253c25ae639797df2d0ff7a35d9d8 upstream.
We were getting build warning about:
drivers/gpu/drm/gma500/mdfld_dsi_output.c:407:2: warning: initialization
from incompatible pointer type
The callback to dpms was pointing to a helper function which had a
return type of void, whereas the callback should point to a function
which has a return type of int.
On closer look it turned out that we do not need the helper function
since if we call drm_helper_connector_dpms() directly, the first check
that drm_helper_connector_dpms() does is: if (mode == connector->dpms)

commit 4f250706211cdb949f7580d4fe4dd1fd646de693 upstream.
If the DSI output isn't connected, then mdfld_dsi_encoder_get_pipe()
will return -1. The mdfld_dsi_dp_mode_set() function doesn't properly
check for this condition and causes the following compiler warnings:
CC drivers/gpu/drm/gma500/mdfld_dsi_dpi.o
drivers/gpu/drm/gma500/mdfld_dsi_dpi.c: In function ‘mdfld_dsi_dpi_mode_set’:
drivers/gpu/drm/gma500/mdfld_dsi_dpi.c:828:35: warning: array subscript is below array bounds [-Warray-bounds]
u32 pipeconf = dev_priv->pipeconf[pipe];
^
drivers/gpu/drm/gma500/mdfld_dsi_dpi.c:829:33: warning: array subscript is below array bounds [-Warray-bounds]
u32 dspcntr = dev_priv->dspcntr[pipe];
^
Fix this by checking for a valid pipe before indexing the pipeconf and
dspcntr arrays.

commit b74c0a9969f25217a5e5bbcac56a11bee16718d3 upstream.
gcc-4.9 notices that the validate_init() function returns unintialized
data when called with a zero 'nr_buffers' argument, when called with the
-Wmaybe-uninitialized flag:
drivers/gpu/drm/nouveau/nouveau_gem.c: In function ‘validate_init.isra.6’:
drivers/gpu/drm/nouveau/nouveau_gem.c:457:5: error: ‘ret’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
However, the only caller of this function always passes a nonzero
argument, and gcc-6 is clever enough to take this into account and
not warn about it any more.
Adding an explicit initialization to -EINVAL here is correct even if
the caller changed, and it avoids the warning on gcc-4.9 as well.

commit 0e7c875d1ae9dcf4d8c6018a45e5529feaef8956 upstream.
Use the upper_32_bits() macro instead of the four line equivalent that
triggers a GCC warning on 32 bits x86:
drivers/gpu/drm/vmwgfx/vmwgfx_cmdbuf.c: In function 'vmw_cmdbuf_header_submit':

And use the lower_32_bits() macro instead of and-ing with a 32 bits
mask.

commit d18d1a5ac811d12f7ebc1129230312b5f2c50cb8 upstream.
To acquire all modeset locks requires a ww_ctx to be allocated. As this
is the legacy path and the allocation small, to reduce the changes
required (and complex untested error handling) to the legacy drivers, we
simply assume that the allocation succeeds. At present, it relies on the
too-small-to-fail rule, but syzbot found that by injecting a failure
here we would hit the WARN. Document that this allocation must succeed
with __GFP_NOFAIL.

commit 641307df71fe77d7b38a477067495ede05d47295 upstream.
When stopping the CRTC the driver must disable all planes and wait for
the change to take effect at the next vblank. Merely calling
drm_crtc_wait_one_vblank() is not enough, as the function doesn't
include any mechanism to handle the race with vblank interrupts.
Replace the drm_crtc_wait_one_vblank() call with a manual mechanism that
handles the vblank interrupt race.

commit cbbb90b0c084d7dfb2ed8e3fecf8df200fbdd2a0 upstream.
When implementing support for interlaced modes, the driver switched from
reporting vblank events on the vertical blanking (VBK) interrupt to the
frame end interrupt (FRM). This incorrectly divided the reported refresh
rate by two. Fix it by moving back to the VBK interrupt.
Fixes: 906eff7fcada ("drm: rcar-du: Implement support for interlaced modes")
