Display Port (DP) controller has the ability to calculate CRC values
for every frame. In addition, most DP sinks also have the capability
to calculate per frame CRC values. Add support to enable/disable
calculation of per-frame CRC values for both the DP controller and
the DP sink. Add support to read the computed CRC values via a new
sysfs node. See below for usage instructions:
To enable/disable per frame CRC calculation:
* echo "ctl_cr_en=[0/1]" > /sys/class/graphics/<fbi>/frame_crc
* echo "sink_cr_en=[0/1]" > /sys/class/graphics/<fbi>/frame_crc
To read computed CRC values:
* cat /sys/class/graphics/<fbi>/frame_crc

Add node named 'config' to let the user modules know
about the supported DisplayPort configurations. On
every cable connection, user modules can read this sysfs
node to configure accordingly. This sysfs node can also
be used to force a test pattern on the DP interface using
the following syntax:
echo "bpp=<bpp> pattern_type=<pattern>" > /sys/class/graphics/<fbi>/config
where
* bpp = [0/18/24/30]
* pattern_type = [0/1/2/3]

Resolutions listed in the Detailed Timing Descriptor (DTD) have
detailed information about all the timings. Current implementation
attempts to match the parsed resolution with the resolution database
based on just the Video Information Code (VIC). This can potentially
overlook mismatches in certain parameters such as refresh rates and
can cause unintended results. Fix this by always adding the resolutions
parsed from the DTDs to the reserved timing list.

Current implementation of the EDID parser always ensures that
VGA resolution (640x480) is added to the list of supported modes.
However, this should really be done by the client of the parser
based on their policies. This will avoid usecases where the EDID
parser would report the VGA resolution as supported even if it
was not listed in the sink's EDID.

Current implementation utilizes a simple event queue to handle
some of the tasks when setting up or tearing down a display port
session. This is currently achieved using a workqueue and assumes
that there can be at most one unhandled event outstanding. This
may not be valid and can result certain events being skipped.
Refactor this by handling the events in a new event thread.

We assume boot CPU as a sync CPU and initialize it's window_start
to sched_ktime_clock(). As windows are synchronized across all
CPUs, the secondary CPUs' window_start are initialized from the
sync_cpu's window_start. A CPU's window_start is never reset, so
this synchronization happens only once for a given CPU. Given this
fact, there is no need to reassigning the sync_cpu role to another
CPU when the boot CPU is going offline. Remove this unnecessary
maintenance of sync_cpu and use any online CPU's window_start as
reference.

CMA pages are currently replaced in the FUSE file system since
FUSE may hold on to CMA pages for a long time, preventing migration.
The replacement page is added to the file cache but not the LRU
cache. This may prevent the page from being properly aged and dropped,
creating poor performance under tight memory condition. Fix this by
adding the new page to the LRU cache after creation.

Colocation in HMP includes a tunable that turns on or off the feature
globally across all colocation groups. Supporting this tunable correctly
would result in complexity that would outweigh any foreseeable benefits.
For example, disabling the feature globally would involve deleting all
colocation groups one by one while ensuring no placement decisions are
made during the process.
Remove the tunable. Adding or removing a task from a colocation group is
still possible and so we're not losing functionality.

There are certain conditions under which group_will_fit() may return 0 for
all clusters in the system, especially under changing thermal conditions.
This may result in crashes such as this one:
CPU 0 | CPU 1
====================================================================
select_best_cpu() |
-> env.rtg = rtgA |
rtgA.pref_cluster=C_big |
| set_pref_cluster() for rtgA
| -> best_cluster()
| C_little doesn't fit
|
| IRQ: thermal mitigation
| C_big capacity now less
| than C_little capacity
|
| -> best_cluster() continues
| C_big doesn't fit
| set_pref_cluster() sets
| rtgA.pref_cluster = NULL
|
select_least_power_cluster() |
-> cluster_first_cpu() |
-> BUG() |
To add lock protection around accesses to the group's preferred cluster
would be expensive and defeat the point of the usage of RCU to protect
access to the related_thread_group structure. Therefore, ensure that
best_cluster() can never return NULL. In the worst case, we'll select the
wrong cluster for a related_thread_group's demand, but this should be
fixed in the next tick or wakeup etc. Locking would have still led to the
momentary wrong decision with the additional expense!
Also, don't set preferred cluster to NULL when colocation is disabled.
