Add register field descriptors to the ipa_reg structure. A field in
a register is defined by a field mask, which is a 32-bit mask having
a single contiguous range of bits set.
For each register that has at least one field defined, an enumerated
type will identify the register's fields. The ipa_reg structure for
that register will include an array fmask[] of field masks, indexed
by that enumerated type. Each field mask defines the position and
bit width of a field. An additional "fcount" records how many
fields (masks) are defined for a given register.
Introduce two macros to be used to define registers that have at
least one field.
Introduce a few new functions related to field masks. The first
simply returns a field mask, given an IPA register pointer and field
mask ID. A variant of that is meant to be used for the special case
of single-bit field masks.
Next, ipa_reg_encode(), identifies a field with an IPA register
pointer and a field ID, and takes a value to represent in that
field. The result encodes the value in the appropriate place to be
stored in the register. This is roughly modeled after the bitmask
operations (like u32_encode_bits()).
Another function (ipa_reg_decode()) similarly identifies a register
field, but the value supplied to it represents a full register
value. The value encoded in the field is extracted from the value
and returned. This is also roughly modeled after bitmask operations
(such as u32_get_bits()).
Finally, ipa_reg_field_max() returns the maximum value representable
by a field.

to avoid the need for excessive error checking. (A warning is issued
whenever ipa_reg() returns 0).

Create a new subdirectory "reg", which contains a register
definition file for each supported version of IPA. Each register
definition contains the register's offset, and for parameterized
registers, the stride (distance between consecutive instances of the
register). Finally, it includes an all-caps printable register name.
In these files, each IPA version defines an array of IPA register
definition pointers, with unsupported registers defined with a null
pointer. The array is indexed by the ipa_reg_id enumerated type.
At initialization time, the appropriate register definition array to
use is selected based on the IPA version, and assigned to a new
"regs" field in the IPA structure.
Extend ipa_reg_valid() so it fails if a valid register is not
defined.
This patch simply puts this infrastructure in place; the next will

DG2 has issues. To work around one of these the GuC must schedule
apps in an exclusive manner across both RCS and CCS. That is, if a
context from app X is running on RCS then all CCS engines must sit
idle even if there are contexts from apps Y, Z, ... waiting to run. A
certain OS favours RCS to the total starvation of CCS. Linux does not.
Hence the GuC now has a scheduling policy setting to control this
abitration.

The wake up waiters only checks the "wakeup_full" variable and not the
"full_waiters_pending". The full_waiters_pending is set when a waiter is
added to the wait queue. The wakeup_full is only set when an event is
triggered, and it clears the full_waiters_pending to avoid multiple calls
to irq_work_queue().
The irq_work callback really needs to check both wakeup_full as well as
full_waiters_pending such that this code can be used to wake up waiters
when a file is closed that represents the ring buffer and the waiters need
to be woken up.

Some Root Ports on Intel Tiger Lake and Alder Lake systems support the RP
Extensions for DPC and the RP PIO Log registers but incorrectly advertise
an RP PIO Log Size of zero. This means the kernel complains that:
DPC: RP PIO log size 0 is invalid
and if DPC is triggered, the DPC driver will not dump the RP PIO Log
registers when it should.
This is caused by a BIOS bug and should be fixed the BIOS for future CPUs.
Add a quirk to set the correct RP PIO Log size for the affected Root Ports.

For create_rqt, make sure to round up to the power of two the value of

- Under SRIOV, we need to send REQ_GPU_FINI to the hypervisor
during the suspend time. Furthermore, we cannot request a
mode 1 reset under SRIOV as VF. Therefore, we will skip it
as it is called in suspend_noirq() function.
- In the resume code path, we need to send REQ_GPU_INIT to the
hypervisor and also resume PSP IP block under SRIOV.

[Why]
For individual feature testing, PMFW may not report all clock
values back. Driver will default them to 0 but this will
cause the BB table to be skipped and default to one state
with max clocks.
[How]
Add helper function to scan through initial clock values and
populate them with default clock limits so that BB table
can be built.
Add dpm_enabled flag to check when DPM is not enabled and
to trigger helper function.

[Why]
Programming pixel rate divider when FIFO is enabled can cause FIFO error.
[How]
Skip divider programming when divider values are the same to prevent FIFO
error.

Revert "dc: skip audio setup when audio stream is enabled"
This reverts commit 65fbfb02c2
[why]
We have minimal pipe split transition method to avoid pipe
allocation outage.However, this method will invoke audio setup
which cause audio output stuck once pipe reallocate.
[how]
skip audio setup for pipelines which audio stream has been enabled

[Why]
We rely on DMCUB to do this when disabling the link but it should
actually come before we disable the DP VID stream.
If we don't then the FIFO can end up with underflow that persists
the next time it's enabled.
[How]
Add a DCN314 specific blank sequence that will disable the DIG FIFO
first.

[Why]
The DIO FIFO will underflow if we turn off the OTG before we turn
off the FIFO.
Since this happens as part of the OTG workaround and we don't reset
the FIFO afterwards we see the error persist.
[How]
Add disable FIFO before the disable CRTC and enable FIFO after enabling
the CRTC.

[Why]
Avoids a race condition where DIO FIFO can underflow due to no incoming
data available.
[How]
Shift the FIFO enable below stream enable.
Make sure fullness level is written before the DIO reset takes place
and that we're not doing it twice.

re-use gds_size for the queue size (unused for KFD). MES requires the
queue size in order to compute the actual wptr offset within the queue
RB since it increases monotonically for AQL queues.
