drm/i915/psr: Do no mask display register writes on hsw/bdw
hsw/bdw lack the pipe register vs. display register distinction
in their PSR masking capabilities. So to keep our CURSURFLIVE
tricks working we need to just unmask all display register writes
on these platforms. The downside being that any display regitster
(eg. even SWF regs) will cause a PSR exit.
Note that WaMaskMMIOWriteForPSR asks us to mask this on bdw, but
that won't work since we need those CURSURFLIVE tricks. Observations
on actual hardware show that this causes one extra PSR exit ~every
10 seconds, which is pretty much irrelevant. I suspect this is
due to the pcode poking at IPS_CTL. Disabling IPS does not stop it
however, so either I'm wrong or pcode pokes at the register
regardless of whether it's actually trying to enable/disable IPS.
Also when the machine is busy (eg. just running 'find /') these
extra PSR exits cease, which again points at pcode or some other
PM entity as being the culprit.

drm/i915: use pointer to i915 instead of rpm in wakeref
Currently a pointer to an intel_runtime_pm structure is stored in the
wake reference structures so the runtime data can be accessed. We can
save the entire device information (drm_i915_private) instead, since
we'll need to reference the new workqueue we'll add in subsequent
patches.

- Return 0 when user queries if there was a h/w or f/w error and no such error happened.
Previously we returned an error in such case.
- New features and improvements:
- Add pci health check when we lose connection with the firmware. This can be used to
distinguish between pci link down and firmware getting stuck.
- Add more info to the error print when TPC interrupt occur.
- Reduce amount of code under mutex in the command submission of signal event.
- Firmware related fixes:
- Fixes to the handshake protocol during f/w initialization.
- Display information that the f/w sends us when encountering a DMA error.
- Do soft-reset using a message sent to firmware instead of writing to MMIO.
- Prepare generic code to extract f/w version numbers.
- Bug fixes and code cleanups. Notable fixes are:
- Unsecure certain TPC registers that the user should access.
- Fix handling of QMAN errors
- Fix memory leak when recording errors (to later pass them to the user)
- Multiple fixes to razwi interrupt handling code

gma_bottom in several functions to calculate the size of the command

i915/perf: Drop the aging_tail logic in perf OA
On DG2, capturing OA reports while running heavy render workloads
sometimes results in invalid OA reports where 64-byte chunks inside
reports have stale values. Under memory pressure, high OA sampling rates
(13.3 us) and heavy render workload, occasionally, the OA HW TAIL
pointer does not progress as fast as the sampling rate. When these
glitches occur, the TAIL pointer takes approx. 200us to progress. While
this is expected behavior from the HW perspective, invalid reports are
not expected.
In oa_buffer_check_unlocked(), when we execute the if condition, we are
updating the oa_buffer.tail to the aging tail and then setting pollin
based on this tail value, however, we do not have a chance to rewind and
validate the reports prior to setting pollin. The validation happens
in a subsequent call to oa_buffer_check_unlocked(). If a read occurs
before this validation, then we end up reading reports up until this
oa_buffer.tail value which includes invalid reports. Though found on
DG2, this affects all platforms.
The aging tail logic is no longer necessary since we are explicitly
checking for landed reports.
Start by dropping the aging tail logic.
v2:
- Drop extra blank line
- Add reason to drop aging logic (Ashutosh)
- Add bug links (Ashutosh)
- rename aged_tail to read_tail
- Squash patches 3 and 1

drm/i915: Allow user to set cache at BO creation
To comply with the design that buffer objects shall have immutable
cache setting through out their life cycle, {set, get}_caching ioctl's
are no longer supported from MTL onward. With that change caching
policy can only be set at object creation time. The current code
applies a default (platform dependent) cache setting for all objects.
However this is not optimal for performance tuning. The patch extends
the existing gem_create uAPI to let user set PAT index for the object
at creation time.
The new extension is platform independent, so UMD's can switch to using
this extension for older platforms as well, while {set, get}_caching are
still supported on these legacy paltforms for compatibility reason.
However, since PAT index was not clearly defined for platforms prior to
GEN12 (TGL), so we are limiting this externsion to GEN12+ platforms
only. See ext_set_pat() in for the implementation details.
The documentation related to the PAT/MOCS tables is currently available
for Tiger Lake here:
https://www.intel.com/content/www/us/en/docs/graphics-for-linux/developer-reference/1-0/tiger-lake.html
The documentation for other platforms is currently being updated.
