Make sure to use proper locks when using the
vma_struct_area. This will avoid the race condition
in a scenario where one thread gets a vma_struct_area
and other thread is unmapping the vma from the process.

This reverts commit 45380e224102 ("msm: sde: add early
display handoff feature"). To avoid conflict when
syncing up with mainline, we revert this change.

When enabling animation/state splash in LK, drm/kms driver needs
to involve handoff code to support smooth transition. In display
probe it will do following items:
1. Check the status in LK for early splash.
2. Handle SMMU mapping issue to avoid SMMU fault problem.
3. Reserved memory, and bypass hardware reset to avoid glitch.
And after user's space is up, when first commit comes, it will call
sde_splash_clean_up to:
1. tell LK to stop splash and to exit.
2. set early_domain_map_attr to 1 to enable stage 1 translation in
iommu driver.
3. free the memory to system.

In case memory pools are supported return the page size as
supported only if corresponding memory pool is available.
This will increase the usage of memory pool and will reduce the
overall allocation time.

Return value of snprintf doesn't account for the terminating
null character it appends to the end of every string.
So this change adds one extra character length to the blob size
to avoid over reading from the client end.

When enabling early display, disabling weston service and launching
DRM_test, system looks to hang when DRM_test wants to open drm node.
The hang is caused by mutex deadlock.
So refine the code and remove the mutex lock to fix the problem.

This change enables a new LP property to specify panel specific
low power modes. This is needed to differentiate between normal
panel "on" and "on but low power" scenarios, something that
is not available through the standard DRM DPMS property.
The sde connector calculates a consolidated "power mode" setting
between the DPMS and LP properties and provides a callback to
the underlying display driver(s) whenever one of them is updated.

Add enabled flag to the CRTC to be able to track the enabled or
disabled status in the display thread instead of the atomic
state. The atomic state is swapped prior to the display thread
dispatch. This is before the display thread executes the enable
or disable operation, so the state is not properly reflected for
a running VSYNC work item.
Also, simplify the CRTC VBLANK function structure to use a
single common function call to update the CRTC's VBLANK
registration with the encoder to avoid extra refs and unrefs.

[ Upstream commit 88b333b0ed790f9433ff542b163bf972953b74d3 ]
Currently the value written to CP_RB_WPTR is calculated on the fly as
(rb->next - rb->start). But as the code is designed rb->next is wrapped
before writing the commands so if a series of commands happened to
fit perfectly in the ringbuffer, rb->next would end up being equal to
rb->size / 4 and thus result in an out of bounds address to CP_RB_WPTR.
The easiest way to fix this is to mask WPTR when writing it to the
hardware; it makes the hardware happy and the rest of the ringbuffer
math appears to work and there isn't any point in upsetting anything.

commit 4f7b0d263833928e947e172eff2d2997179c5cb9 upstream.
It isn't safe to call drm_dev_unregister() without first initializing
mode setting with drm_mode_config_init(). This leads to a crash if
either IO memory can't be remapped or vblank initialization fails.
Fix this by reordering the initialization sequence. Move vblank
initialization after the drm_mode_config_init() call, and move IO
remapping before drm_dev_alloc() to avoid the need to perform clean up
in case of failure.
While at it remove the explicit drm_vblank_cleanup() call from
rcar_du_remove() as the drm_dev_unregister() function already cleans up
vblank.

commit c1d4b38c93069dca6b419a3b88907e01e2c3abf7 upstream.
The drm driver .load() operation is prone to race conditions as it
initializes the driver after registering the device nodes. Its usage is
deprecated, inline it in the probe function and call drm_dev_alloc() and
drm_dev_register() explicitly.
For consistency inline the .unload() handler in the remove function as
well.

commit 38bcb208f60924a031b9f809f7cd252ea4a94e5f upstream.
Bit 30 being set causes the upper half of BAR2 to stay in physical mode,
mapped over the end of VRAM, even when the rest of the BAR has been set
to virtual mode.
We inherited our initial value from RM, but I'm not aware of any reason
we need to keep it that way.
This fixes severe GPU hang/lockup issues revealed by Wayland on F26.
Shout-out to NVIDIA for the quick response with the potential cause!

The current code does not look correct, and the reason for it is
probably lost. Since this now generates a compiler warning,
fix it to what makes sense.

commit 636c4c3e762b62aa93632c645ca65879285b16e3 upstream.
Currently we may process up/down message transactions containing
uninitialized data. This can happen if there was an error during the
reception of any message in the transaction, but we happened to receive
the last message correctly with the end-of-message flag set.
To avoid this abort the reception of the transaction when the first
error is detected, rejecting any messages until a message with the
start-of-message flag is received (which will start a new transaction).
This is also what the DP 1.4 spec 2.11.8.2 calls for in this case.
In addtion this also prevents receiving bogus transactions without the
first message with the the start-of-message flag set.
v2:
- unchanged
v3:
- git add the part that actually skips messages after an error in
drm_dp_sideband_msg_build()

commit 564d8a2cf3abf16575af48bdc3e86e92ee8a617d upstream.
The late 2009, 27 inch Apple iMac10,1 has an
internal eDP display and an external Mini-
Displayport output, driven by a DCE-3.2, RV730
Radeon Mobility HD-4670.
The machine worked fine in a dual-display setup
with eDP panel + externally connected HDMI
or DVI-D digital display sink, connected via
MiniDP to DVI or HDMI adapter.
However, booting the machine single-display with
only eDP panel results in a completely black
display - even backlight powering off, as soon as
the radeon modesetting driver loads.
This patch fixes the single dispay eDP case by
assigning encoders based on dig->linkb, similar
to DCE-4+. While this should not be generally
necessary (Alex: "...atom on normal boards
should be able to handle any mapping."), Apple
seems to use some special routing here.
One remaining problem not solved by this patch
is that an external Minidisplayport->DP sink
does still not work on iMac10,1, whereas external
DVI and HDMI sinks continue to work.
The problem affects at least all tested kernels
since Linux 3.13 - didn't test earlier kernels, so
backporting to stable probably makes sense.
v2: With the original patch from 2016, Alex was worried it
will break other DCE3.2 systems. Use dmi_match() to
apply this special encoder assignment only for the
Apple iMac 10,1 from late 2009.

This patch addresses an issue in the GPU init sequence where
the clocks are turned on during the process but after the
init is complete the clocks are not turned off. Due to this,
the GPU clocks always have a refcount delta of 1 and never
get disabled later even when explicitly requested.

After enabling the GPU clocks, the GPU can pagefault
when trying to access memory(example the ringbuffer).
This patch addresses the pagefault issue by enabling
the memory retention flags on the GPU core clock.
