This kernel module is used for testing. It's safe to say M here.
It can also be built-in without X86_AMD_PSTATE enabled.
Currently, only tests for amd-pstate are supported. If X86_AMD_PSTATE
is set disabled, it can tell the users test can only run on amd-pstate
driver, please set X86_AMD_PSTATE enabled.
In the future, comparison tests will be added. It can set amd-pstate
disabled and set acpi-cpufreq enabled to run test cases, then compare
the test results.

Expose struct amd_cpudata to AMD P-State unit test module.
This data struct will be used on the following AMD P-State unit test
(amd-pstate-ut) module. The amd-pstate-ut module can get some
AMD infomations by this data struct. For example: highest perf,
nominal perf, boost supported etc.

Commit 6240aaad75e1 was supposed to drop the reference count to the OPP,
instead it avoided more stuff if the OPP isn't found. This isn't
entirely correct. We already have a frequency value available, we just
couldn't align it with an OPP in case of IS_ERR(opp).
Lets continue with updating thermal pressure, etc, even if we aren't
able to find an OPP here.
This fixes warning generated by the 'smatch' tool.

Users may disable HWP in firmware, in which case intel_pstate wouldn't load
unless the CPU model is explicitly supported.
Add TIGERLAKE to the list of CPUs that can register intel_pstate while not
advertising the HWP capability. Without this change, an TIGERLAKE in no-HWP
mode could only use the acpi_cpufreq frequency scaling driver.

To avoid some new AMD processors use wrong highest perf when amd pstate
driver loaded, this fix will query the highest perf from MSR register
MSR_AMD_CPPC_CAP1 and cppc_acpi interface firstly, then compare with the
highest perf value got by calling amd_get_highest_perf() function.
The lower value will be the correct highest perf we need to use.
Otherwise the CPU max MHz will be incorrect if the
amd_get_highest_perf() did not cover the new process family and model ID.
Like this lscpu info, the max frequency is incorrect.

Change the default transition latency to be 20ms that is more
reasonable transition delay for AMD processors in non-EPP driver mode.
Update transition delay time to 1ms, in the AMD CPU autonomous mode and
non-autonomous mode, CPPC firmware will decide frequency at 1ms timescale
based on the workload utilization.

The patch will fix the invalid desired perf value for powersave
governor. This issue is found when testing on one AMD EPYC system, the
actual des_perf is smaller than the min_perf value, that is invalid
value. because the min_perf is the lowest_perf system can support in
idle state.

Merge new material related to CPPC, PCC, APEI and OSI strings handling
for 6.1-rc1:
- Disable frequency invariance in the CPPC library if registers used
by cppc_get_perf_ctrs() are accessed via PCC (Jeremy Linton).
- Add ACPI disabled check to acpi_cpc_valid() (Perry Yuan).
- Fix Tx acknowledge in the PCC address space handler (Huisong Li).
- Use wait_for_completion_timeout() for PCC mailbox operations (Huisong
Li).
- Release resources on PCC address space setup failure path (Rafael
Mendonca).
- Remove unneeded result variables from APEI code (ye xingchen).
- Print total number of records found during BERT log parsing (Dmitry
Monakhov).
- Drop support for 3 _OSI strings that should not be necessary any
more and update documentation on custom _OSI strings so that adding
new ones is not encouraged any more (Mario Limonciello).
* acpi-cppc:
ACPI: CPPC: Disable FIE if registers in PCC regions
ACPI: CPPC: Add ACPI disabled check to acpi_cpc_valid()
* acpi-pcc:
ACPI: PCC: Fix Tx acknowledge in the PCC address space handler
ACPI: PCC: replace wait_for_completion()
ACPI: PCC: Release resources on address space setup failure path
* acpi-apei:
ACPI: APEI: Remove unneeded result variables

* acpi-osi:
ACPI: OSI: Update Documentation on custom _OSI strings
ACPI: OSI: Remove Linux-HPI-Hybrid-Graphics _OSI string
ACPI: OSI: Remove Linux-Lenovo-NV-HDMI-Audio _OSI string
ACPI: OSI: Remove Linux-Dell-Video _OSI string

PCC regions utilize a mailbox to set/retrieve register values used by
the CPPC code. This is fine as long as the operations are
infrequent. With the FIE code enabled though the overhead can range
from 2-11% of system CPU overhead (ex: as measured by top) on Arm
based machines.
So, before enabling FIE assure none of the registers used by
cppc_get_perf_ctrs() are in the PCC region. Finally, add a module
parameter which can override the PCC region detection at boot or
module reload.

Make acpi_cpc_valid() check if ACPI is disabled, so that its callers
don't need to check that separately. This will also cause the AMD
pstate driver to refuse to load right away when ACPI is disabled.
Also update the warning message in amd_pstate_init() to mention the
ACPI disabled case for completeness.

There is no need to check if the cpufreq driver implements callback
cpufreq_driver::target_index. The logic in the __resolve_freq uses
the frequency table available in the policy. It doesn't matter if the
driver provides 'target_index' or 'target' callback. It just has to
populate the 'policy->freq_table'.
Thus, check only frequency table during the frequency resolving call.

From a state where all policy->related_cpus are offline, putting one
of the policy's CPU back online re-activates the policy by:
1. Calling cpufreq_driver->online()
2. Setting the CPU in policy->cpus
qcom_cpufreq_hw_cpu_online() makes use of policy->cpus. Thus 1. and 2.
should be inverted to avoid having a policy->cpus empty. The
qcom-cpufreq-hw is the only driver affected by this.

If LMH (Limits Management Hardware) is available, when a policy is
disabled by unplugging the last online CPU of policy->cpus, the LMH
irq is left enabled.
When the policy is re-enabled with any of the CPU in policy->cpus
being plugged in, qcom_cpufreq_ready() re-enables the irq. This
triggers the following warning:
[ 379.160106] Unbalanced enable for IRQ 154

If LMH (Limits Management Hardware) is available, when a policy is
disabled by unplugging the last online CPU of policy->cpus,
qcom_cpufreq_hw_cpu_offline() sets cancel_throttle=true.
cancel_throttle is not reset when the policy is re-enabled with any
of the CPU in policy->cpus being plugged in. So reset it.
This patch also adds an early exit check.

Merge core device power management changes for v5.20-rc1:
- Extend support for wakeirq to callback wrappers used during system
suspend and resume (Ulf Hansson).
- Defer waiting for device probe before loading a hibernation image
till the first actual device access to avoid possible deadlocks
reported by syzbot (Tetsuo Handa).
- Unify device_init_wakeup() for PM_SLEEP and !PM_SLEEP (Bjorn
Helgaas).
- Add Raptor Lake-P to the list of processors supported by the Intel
RAPL driver (George D Sworo).
- Add Alder Lake-N and Raptor Lake-P to the list of processors for
which Power Limit4 is supported in the Intel RAPL driver (Sumeet
Pawnikar).
- Make pm_genpd_remove() check genpd_debugfs_dir against NULL before
attempting to remove it (Hsin-Yi Wang).
- Change the Energy Model code to represent power in micro-Watts and
adjust its users accordingly (Lukasz Luba).
