Prevent other bits of mailbox power limit from being overwritten with 0.
This issue was due to a missing read and modify of current power limit,
before setting a requested mailbox power limit, which is added in this
patch.
v2:
- Improve commit message. (Anshuman)
v3:
- Rebase.
- Rephrase commit message. (Riana)
- Add read-modify-write variant of xe_hwmon_pcode_write_power_limit()
i.e. xe_hwmon_pcode_rmw_power_limit(). (Badal)
- Use xe_hwmon_pcode_rmw_power_limit() to set mailbox power limits.
- Remove xe_hwmon_pcode_write_power_limit() as all mailbox power limits
writes use xe_hwmon_pcode_rmw_power_limit() only.
v4:
- Use PWR_LIM in place of (PWR_LIM_EN | PWR_LIM_VAL) wherever
applicable. (Riana)

vmwgfx's fencing predates dma_fence and as a result dma_fence_ops was never
properly implemented, especially with respect to enabling signaling.
Because of this dma_fence callbacks don't work properly. This change
implements enable_signaling properly so that dma_fence callbacks now
work as expected.
It also removes vmwgfx's custom implementation of fence callbacks
and removes vmwgfx's custom dma_fence_ops::wait function which is no
longer necessary now that enable_signaling works.

There was a possible race in vmw_update_seqno. Because of this race it
was possible for last_read_seqno to go backwards. Remove this function
and replace it with vmw_update_fences which now sets and returns the
last_read_seqno while holding the fence lock. This serialization via the
fence lock ensures that last_read_seqno is monotonic again.

If a range or VMA is invalidated and scratch page is disabled, there
is no reason to issue a TLB invalidation on unbind, skip TLB
innvalidation is this condition is true. This is an opportunistic check
as it is done without the notifier lock, thus it possible for the range
to be invalidated after this check is performed.
This should improve performance of the SVM garbage collector, for
example, xe_exec_system_allocator --r many-stride-new-prefetch, went
~20s to ~9.5s on a BMG.
v2:
- Use helper for valid check (Thomas)
v3:
- Avoid skipping TLB invalidation if PTEs are removed at a higher
level than the range
- Never skip TLB invalidations for VMA
- Drop Himal's RB

This WA is applicable to BMG as well.
Note that this is a GSC WA and we don't load the GSC on BMG, so
extending the WA to BMG won't do anything right now. However, it helps
future-proof the driver so that if we ever turn the GSC on we won't have
to remember to extend this WA.

Currently xe sets the guc log level to a verbose level since it's useful
to debug hangs and general development. However the verbose level may
already be too much and affect performance.
Michal Mrozek did some tests with the L0 compute stack for submission
latency with ULLS disabled. Below are the normalized numbers with log
level 3 (the current default) as baseline for each test:
Test \ Log Level 3 0 1 2
----------------------------------------------------------- ------ ------ ------ ------
BestWalkerNthCommandListSubmission(CmdListCount=2) 1.00 0.63 0.63 0.96
BestWalkerNthSubmission(KernelCount=2) 1.00 0.62 0.63 0.96
BestWalkerNthSubmissionImmediate(KernelCount=2) 1.00 0.58 0.58 0.85
BestWalkerSubmission 1.00 0.62 0.62 0.96
BestWalkerSubmissionImmediate 1.00 0.63 0.62 0.96
BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=2) 1.00 0.58 0.58 0.86
BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=4) 1.00 0.70 0.70 0.83
BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=8) 1.00 0.53 0.52 0.78
Log level 2 is the first "verbose level" for GuC, where the biggest
difference happens. Keep log level 3 for CONFIG_DRM_XE_DEBUG, but switch
to 1, i.e. GUC_LOG_LEVEL_NON_VERBOSE, for "normal" builds.

When using the flip queue, due to the DMC vs. DSB register corruption
problem, we must not issue any register writes from the DSB after
unhalting the DMC. Currently we are doing just that by trying to
restore DSB_PMCTRL* back to a sane state from intel_dsb_finish().
Since the only place left that pokes at DSB_PMCTRL* is intel_dsb_chain()
we can just do DSB_PMCTRL_2/DSB_FORCE_DEWAKE reset in the same place.
The DSB_PMCTRL reset is trickier since we'd have to do it from the
chained DSB itself. But based on my earlier testing
DSB_PMCTRL/DSB_ENABLE_DEWAKE doesn't actually do anything if the DSB
isn't actually enabled, so we can omit the reset to keep things a bit
simpler. We do need to reset DSB_PMCTRL/DSB_ENABLE_DEWAKE before
tarting the DSB however, in case it was left enabled from a previous
use.

Since the introduction of DSB chaining we no longer need the
DEwake tricks in intel_dsb_commit().
I also need to relocate the DSB_PMCTRL* writes out of
intel_dsb_finish() (due to the flip queue DMC vs. DSB register
corruption issues), and it'll be a bit more straightforward if
I don't have to worry about the non-chained DSB path anymore.

If the free_post is not QW aligned we don't have to memset the
extra DW needed to make it so, as the only way that can happen
is via intel_dsb_reg_write_indexed() which already makes sure
the next DW is zeroed.
Not a big deal, but this is more consistent how all the other
stuff operates that puts instructions into the DSB buffer, and
we'll get a few more of those soon.

When a device get wedged, it might be caused by a guilty application.
For userspace, knowing which task was involved can be useful for some
situations, like for implementing a policy, logs or for giving a chance
for the compositor to let the user know what task was involved in the
problem. This is an optional argument, when the task info is not
available, the PID and TASK string won't appear in the event string.
Sometimes just the PID isn't enough giving that the task might be already
dead by the time userspace will try to check what was this PID's name,
so to make the life easier also notify what's the task's name in the user
event.

Now that the PAT settings for the new special entries introduced by Xe2
are decided during early software init and left NULL on platforms they
don't apply to, there's no need to keep separate programming functions
for pre-Xe2 and post-Xe2 platforms. Consolidate down to a single pair
of programming functions (mcr and non-mcr) that can be used on any
platform.

Decide whether programming of the special ATS and PTA PAT entries is
necessary (and which entries should be programmed) during early software
initialization rather than hardcoding this into the 'program' functions.
Future platforms may want to re-use the same functions but utilize
different special entry values. Consolidating all of the decisions
into one place keeps things simple.

Introduce a new parameter to the DRM_IVPU_CMDQ_CREATE ioctl,
enabling turbo mode for jobs submitted via the command queue.
Turbo mode allows jobs to run at higher frequencies,
potentially improving performance for demanding workloads.
Also adds the IVPU_TEST_MODE_TURBO_DISABLE flag to allow test
mode to explicitly disable turbo mode requested by the application.
The IVPU_TEST_MODE_TURBO mode has been renamed to
IVPU_TEST_MODE_TURBO_ENABLE for clarity and consistency.
