__print_symbolic() is designed for exporting the print formatting table to
userspace and allows parsing tool, such as trace-cmd and perf, to analyze
trace log according to this print formatting table, meanwhile, by using
__print_symbolic()s, save space in the trace ring buffer.
original print format:
print fmt: "%s: %s: HDR:%s, CDB:%s", __get_str(str), __get_str(dev_name),
__print_hex(REC->hdr, sizeof(REC->hdr)),
__print_hex(REC->tsf, sizeof(REC->tsf))
after this change:
print fmt: "%s: %s: HDR:%s, CDB:%s",
print_symbolic(REC->str_t, {0, "send"},
{1, "complete"},
{2, "dev_complete"},
{3, "query_send"},
{4, "query_complete"},
{5, "query_complete_err"},
{6, "tm_send"},
{7, "tm_complete"},
{8, "tm_complete_err"}),
__get_str(dev_name), __print_hex(REC->hdr, sizeof(REC->hdr)),
__print_hex(REC->tsf, sizeof(REC->tsf))
Note: This patch just converts current __get_str(str) to __print_symbolic(),
the original tracing log will not be affected by this change, so it
doesn't break what current parsers expect.

The UniPro specification states that attribute IDs of the following
parameters are vendor-specific so some SoCs could have no regions at the
defined addresses:
- DME_LocalFC0ProtectionTimeOutVal
- DME_LocalTC0ReplayTimeOutVal
- DME_LocalAFC0ReqTimeOutVal
In addition, the following parameters should be set considering the
compatibility between host and device.
- PA_PWRMODEUSERDATA0
- PA_PWRMODEUSERDATA1
- PA_PWRMODEUSERDATA2
- PA_PWRMODEUSERDATA3
- PA_PWRMODEUSERDATA4
- PA_PWRMODEUSERDATA5
Introduce a quirk to allow vendor drivers to override the UniPro defaults.

Pull power management fixes from Rafael Wysocki:
"These fix a crash in intel_pstate during resume from suspend-to-RAM
that may occur after recent changes and two resource leaks in error
paths in the operating performance points (OPP) framework, add a new
C-states table to intel_idle and update the cpuidle MAINTAINERS entry
to cover the governors too.
Specifics:
- Fix recently introduced crash in the intel_pstate driver that
occurs if scale-invariance is disabled during resume from
suspend-to-RAM due to inconsistent changes of APERF or MPERF MSR
values made by the platform firmware (Rafael Wysocki).
- Fix a memory leak and add a missing clk_put() in error paths in the
OPP framework (Quanyang Wang, Viresh Kumar).
- Add new C-states table for SnowRidge processors to the intel_idle

- Update the MAINTAINERS entry for cpuidle to make it clear that the
governors are covered by it too (Lukas Bulwahn)"

Pull SCSI fixes from James Bottomley:
"This is a load of driver fixes (12 ufs, 1 mpt3sas, 1 cxgbi).
The big core two fixes are for power management ("block: Do not accept
any requests while suspended" and "block: Fix a race in the runtime
power management code") which finally sorts out the resume problems
we've occasionally been having.
To make the resume fix, there are seven necessary precursors which
effectively renames REQ_PREEMPT to REQ_PM, so every "special" request
in block is automatically a power management exempt one.
All of the non-PM preempt cases are removed except for the one in the
SCSI Parallel Interface (spi) domain validation which is a genuine
case where we have to run requests at high priority to validate the
bus so this becomes an autopm get/put protected request"

Add C-state table for the SnowRidge SoC which is found on Intel Jacobsville
platforms.
The following has been changed.
1. C1E latency changed from 10us to 15us. It was measured using the
open source "wult" tool (the "nic" method, 15us is the 99.99th
percentile).
2. C1E power break even changed from 20us to 25us, which may result
in less C1E residency in some workloads.
3. C6 latency changed from 50us to 130us. Measured the same way as C1E.
The C6 C-state is supported only by some SnowRidge revisions, so add a C-state
table commentary about this.
On SnowRidge, C6 support is enumerated via the usual mechanism: "mwait" leaf of
the "cpuid" instruction. The 'intel_idle' driver does check this leaf, so even
though C6 is present in the table, the driver will only use it if the CPU does
support it.

When sugov_update_single_perf() falls back to the "frequency"
path due to the missing scale-invariance, it will call
cpufreq_driver_fast_switch() via sugov_fast_switch()
and the driver's ->fast_switch() callback will be invoked,
so it must not be NULL.
However, after commit a365ab6b9dfb ("cpufreq: intel_pstate: Implement
the ->adjust_perf() callback") intel_pstate sets ->fast_switch() to
NULL when it is going to use intel_cpufreq_adjust_perf(), which is a
mistake, because on x86 the scale-invariance may be turned off
dynamically, so modify it to retain the original ->adjust_perf()
callback pointer.

In function _allocate_opp_table, opp_dev is allocated and referenced
by opp_table via _add_opp_dev. But in the case that the subsequent calls
return -EPROBE_DEFER, it will jump to err label and opp_table will be
freed. Then opp_dev becomes an unreferenced object to cause memory leak.
So let's call _remove_opp_dev to do the cleanup.
This fixes the following kmemleak report:
unreferenced object 0xffff000801524a00 (size 128):

Commit b9ac0f9dc8ea ("PCI: dwc: Move dw_pcie_setup_rc() to DWC common

0005:03:00.0 USB controller: PLX Technology, Inc. Device 3380 (rev ab)
The problem seems to be dw_pcie_setup_rc() is now called twice before and
after the link up handling. The fix is to move Tegra's link up handling to
.start_link() function like other DWC drivers. Tegra is a bit more
complicated than others as it re-inits the whole DWC controller to retry
the link. With this, the initialization ordering is restored to match the
prior sequence.

clang (quite rightly) complains fairly loudly about the newly added
mpc1_get_mpc_out_mux() function returning an uninitialized value if the

This may not happen in practice, but the code really shouldn't return
garbage if the sanity checks don't pass.
So just initialize 'val' to zero to avoid the issue.

Swap the calling sequence of krealloc() and __request_region(), call the
latter first. In this way, the value of dev_dax->nr_range does not need to
be considered when __request_region() failed.

EDID parsing in S3 resume pushes new display modes
to probed_modes list but doesn't consolidate to actual
mode list. This creates a race condition when
amdgpu_dm_connector_ddc_get_modes() re-initializes the
list head without walking the list and results in memory leak.

[Why]
We defer clock updates to after pipes have been programmed. In
some instances we use DPPCLK that have been previously set to be
"unused". This results in a brief window of time where underflow
could occur.
[How]
During prepare bandwidth allow rn_update_clocks_update_dpp_dto
to check each instance and compare previous clock to new clock.
If new clock is higher than previous clock, program DPPDTO.

[WHY]
DSC should only be acquired per OPP. Therefore, DSC should only
be acquired for the top_pipe when ODM is enabled.
Not doing this check may lead to acquiring more DSC's than needed
when doing MPO + ODM Combine.

Only acquire DSC if pipe is top_pipe.

[Why]
there is some garbage showing up during reboot test.
Reason:
SMU might handle display driver msg defered and driver will send
next msg to SMU after 10ms timeout, once SMU FW handle previous msg,
parameters are changed to next one, which result in a wrong value be programmed.
[How]
Extend timeout to 2s so SMU will have enough time to handle driver msg.
