The HW recovers from the corrupted state after a system suspend/resume

The setting of MSA is done by the DDI .pre_enable() hook. And when we are
using MST, the MSA is only set to first mst stream by calling of

Wrong MSA or missed MSA packets might show scrambled screen or wrong

This splits a setting of MSA to MST and SST cases. And In the MST case it
will call a setting of MSA after an allocating of Virtual Channel from

The gem_ctx_persistence/smoketest was detecting an odd coherency issue
inside the LRC context image; that the address of the ring buffer did
not match our associated struct intel_ring. As we set the address into
the context image when we pin the ring buffer into place before the
context is active, that leaves the question of where did it get
overwritten. Either the HW context save occurred after our pin which
would imply that our idle barriers are broken, or we overwrote the
context image ourselves. It is only in reset_active() where we dabble
inside the context image outside of a serialised path from schedule-out;
but we could equally perform the operation inside schedule-in which is
then fully serialised with the context pin -- and remains serialised by
the engine pulse with kill_context(). (The only downside, aside from
doing more work inside the engine->active.lock, was the plan to merge
all the reset paths into doing their context scrubbing on schedule-out
needs more thought.)

set_page_dirty says:
For pages with a mapping this should be done under the page lock
for the benefit of asynchronous memory errors who prefer a
consistent dirty state. This rule can be broken in some special
cases, but should be better not to.
Under those rules, it is only safe for us to use the plain set_page_dirty
calls for shmemfs/anonymous memory. Userptr may be used with real
mappings and so needs to use the locked version (set_page_dirty_lock).
However, following a try_to_unmap() we may want to remove the userptr and
so call put_pages(). However, try_to_unmap() acquires the page lock and
so we must avoid recursively locking the pages ourselves -- which means
that we cannot safely acquire the lock around set_page_dirty(). Since we
can't be sure of the lock, we have to risk skip dirtying the page, or
else risk calling set_page_dirty() without a lock and so risk fs
corruption.

Inside print_request(), we query the context/timeline name. Nothing
immediately protects the context from being freed if the request is
complete -- we rely on serialisation by the caller to keep the name
valid until they finish using it. Inside intel_engine_dump(), we
generally only print the requests in the execution queue protected by the
engine->active.lock, but we also show the pending execlists ports which
are not protected and so require a rcu_read_lock to keep the pointer
valid.

[Why]
On Navi10, and presumably arcterus, updating pp_table via sysfs would
not re-scale the maximum possible power limit one can set. On navi10,
the SMU code ignored the power percentage overdrive setting entirely,
and would not allow you to exceed the default power limit at all.
[How]
Adding a function to the SMU interface to get the pptable version of the
default power limit allows ASIC-specific code to provide the correct
maximum-settable power limit for the current pptable.

When a jump_whitelist bitmap is reused, it needs to be cleared.
Currently this is done with memset() and the size calculation assumes
bitmaps are made of 32-bit words, not longs. So on 64-bit
architectures, only the first half of the bitmap is cleared.
If some whitelist bits are carried over between successive batches
submitted on the same context, this will presumably allow embedding
the rogue instructions that we're trying to reject.
Use bitmap_zero() instead, which gets the calculation right.

The LUTs are single buffered so in order to program them without
tearing we'd have to do it during vblank (actually to be 100%
effective it has to happen between start of vblank and frame start).
We have no proper mechanism for that at the moment so we just
defer loading them after the vblank waits have happened. That
is not quite sufficient (especially when committing multiple pipes
whose vblanks don't line up) so the LUT load will often leak into
the following frame causing tearing.
However in case the hardware wasn't previously using the LUT we
can preload it before setting the enable bit (which is double
buffered so won't tear). Let's determine if we can do such
preloading and make it happen. Slight variation between the
hardware requires some platforms specifics in the checks.
Hans is seeing ugly colored flash on VLV/CHV macchines (GPD win
and Asus T100HA) when the gamma LUT gets loaded for the first
time as the BIOS has left some junk in the LUT memory.

Not sure if we shouldn't disable dumb buffer support entirely

Here is a mix of a number of IIO driver fixes for 5.4-rc7, and a whole
new staging driver.
The IIO fixes resolve some reported issues, all are tiny.
The staging driver addition is the vboxsf filesystem, which is the
VirtualBox guest shared folder code. Hans has been trying to get
filesystem reviewers to review the code for many months now, and
Christoph finally said to just merge it in staging now as it is
stand-alone and the filesystem people can review it easier over time
that way.
I know it's late for this big of an addition, but it is stand-alone.
The code has been in linux-next for a while, long enough to pick up a
few tiny fixes for it already so people are looking at it.
All of these have been in linux-next with no reported issues.

Pull x86 fixes from Thomas Gleixner:
"A small set of fixes for x86:
- Make the tsc=reliable/nowatchdog command line parameter work again.
It was broken with the introduction of the early TSC clocksource.
- Prevent the evaluation of exception stacks before they are set up.
This causes a crash in dumpstack because the stack walk termination
gets screwed up.
- Prevent a NULL pointer dereference in the rescource control file
system.
- Avoid bogus warnings about APIC id mismatch related to the LDR
which can happen when the LDR is not in use and therefore not
initialized. Only evaluate that when the APIC is in logical
destination mode"

Pull timer fixes from Thomas Gleixner:
"A small set of fixes for timekeepoing and clocksource drivers:
- VDSO data was updated conditional on the availability of a VDSO
capable clocksource. This causes the VDSO functions which do not
depend on a VDSO capable clocksource to operate on stale data.
Always update unconditionally.
- Prevent a double free in the mediatek driver

initialize non-existing interrupts"
