On commit 254852b
(msm: kgsl: Increase worker thread priority), we had increased
the priority for better rendering frames.
Since a lot of display related tasks are multiplexed on KGSL on a
dedicated thread, they are placed in a FIFO manner, which is a bit
of time consuming since not all those queued tasks have a known or
small execution period.
switching to Round-Robin fashion eliminates this complexity and bounds
these tasks on a time-slice and thus every tasks gets executed after
a certain time, as fast as possible.

Currently gpuaddr_in_range() accepts only the gpuaddr & returns
true if it lies in valid range. But this does not mean that the
entire buffer is within range.
Modify the function to accept size as a parameter and check that
both starting & ending points of buffer lie within mmu range.

commit 3059d9b9f6aa433a55b9d0d21b566396d5497c33 upstream.
Transition to drm_mode_fb_cmd2 from drm_mode_fb_cmd left the structure
unitialized. drm_mode_fb_cmd2 adds a few additional members, e.g. flags
and modifiers which were never initialized. Garbage in those members
can cause random failures during the bringup of the fbcon.
Initializing the structure fixes random blank screens after bootup due
to flags/modifiers mismatches during the fbcon bring up.

There's no reason to constantly use snprintf() to generate pretty debug
strings from hot paths. We don't need them, so remove them.
Signed-off-by: Sultan Alsawaf <sultan@kerneltoast.com>
Constantly allocating and freeing all of the data structures associated
with atomic commits adds up and incurs a lot of latency not only when
allocating, but also when freeing. Since we know what the maximum number
of CRTCs, planes, and connectors is, we can skip the constant allocation-
and-free for the same structures and instead just recycle them via a lock-
less list. This also moves the commit cleanup so that it comes after CRTC
waiters are woken up, allowing the ioctl to proceed without waiting around
for some housekeeping to finish.
Since it's difficult to audit which parameters, if any, could exceed the
defined maximums in the msm_kms driver, dynamic allocations are retained as
a fallback so that userspace can't craft a malicious ioctl that results in
buffer overflows.

This reverts commit e3cb7f446cdf36b5e64852c18cd05dde34ecf55f.
This creates a large TTWU burden, which isn't worth it for such a small
amount of cleanup. The cleanup will become inconsequential anyway since the
memory allocations will be replaced with buffer recycling.

Consider a scenario where user allocates anonymous memory but does not
write to it. Here the physical pages are not yet allocated. Now when this
memory is requested to be imported, a list of newly allocated zero pages
is obtained using get_user_pages(). Currently cache flush is not done for
these pages and hence GPU sees stale data. Fix this by performing cache
flush on these pages.

This commit corrects the printing of the IPU clock error percentage if
it is between -0.1% to -0.9%. For example, if the pixel clock requested
is 27.2 MHz but only 27.0 MHz can be achieved the deviation is -0.8%.
But the fixed point math had a flaw and calculated error of 0.2%.
Before:
Clocks: IPU 270000000Hz DI 24716667Hz Needed 27200000Hz
IPU clock can give 27000000 with divider 10, error 0.2%
Want 27200000Hz IPU 270000000Hz DI 24716667Hz using IPU, 27000000Hz
After:
Clocks: IPU 270000000Hz DI 24716667Hz Needed 27200000Hz
IPU clock can give 27000000 with divider 10, error -0.8%
Want 27200000Hz IPU 270000000Hz DI 24716667Hz using IPU, 27000000Hz

As the kmalloc_array() may return null, the 'event_waiters[i].wait' would lead to null-pointer dereference.
Therefore, it is better to check the return value of kmalloc_array() to avoid this confusion.

[ Upstream commit 75478b3b393bcbdca4e6da76fe3a9f1a4133ec5d ]
The current code, when parsing the EDID Deep Color depths, that the
YUV422 cannot be used, referring to the HDMI 1.3 Specification.
This specification, in its section 6.2.4, indeed states:
For each supported Deep Color mode, RGB 4:4:4 shall be supported and
optionally YCBCR 4:4:4 may be supported.
YCBCR 4:2:2 is not permitted for any Deep Color mode.
This indeed can be interpreted like the code does, but the HDMI 1.4
specification further clarifies that statement in its section 6.2.4:
For each supported Deep Color mode, RGB 4:4:4 shall be supported and
optionally YCBCR 4:4:4 may be supported.
YCBCR 4:2:2 is also 36-bit mode but does not require the further use
of the Deep Color modes described in section 6.5.2 and 6.5.3.
This means that, even though YUV422 can be used with 12 bit per color,
it shouldn't be treated as a deep color mode.
This is also broken with YUV444 if it's supported by the display, but
DRM_EDID_HDMI_DC_Y444 isn't set. In such a case, the code will clear
color_formats of the YUV444 support set previously in
drm_parse_cea_ext(), but will not set it back.
Since the formats supported are already setup properly in
drm_parse_cea_ext(), let's just remove the code modifying the formats in
drm_parse_hdmi_deep_color_info()

Please do not apply this to mainline directly, instead please re-run the
coccinelle script shown below and apply its output.
For several reasons, it is desirable to use {READ,WRITE}_ONCE() in
preference to ACCESS_ONCE(), and new code is expected to use one of the
former. So far, there's been no reason to change most existing uses of
ACCESS_ONCE(), as these aren't harmful, and changing them results in
churn.
However, for some features, the read/write distinction is critical to
correct operation. To distinguish these cases, separate read/write
accessors must be used. This patch migrates (most) remaining
ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following
coccinelle script:
----
// Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and
// WRITE_ONCE()
// $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch
