Hi,
These three patches clean up intel_pstate a bit:
[1/3] makes it always use READ_ONCE() for reading hwp_cap_cached
[2/3] changes the first argument of intel_pstate_get_hwp_max()
[3/3] renames to functions (to avoid possible confusion).
Please see patch changelogs for details.
Thanks!
From: Rafael J. Wysocki
Rename intel_cpufreq_adjust_hwp() and intel_cpufreq_adjust_perf_ctl()
to intel_cpufreq_hwp_update() and intel_cpufreq_perf_ctl_update(),
respectively, to avoid possible confusion with the ->adjist_perf()
callback function, intel_cpufreq_adjust_perf().
Signed-
From: Rafael J. Wysocki
All of the callers of intel_pstate_get_hwp_max() access the struct
cpudata object that corresponds to the given CPU already and the
function itself needs to access that object (in order to update
hwp_cap_cached), so modify the code to pass a struct cpudata pointer
From: Rafael J. Wysocki
Because intel_pstate_get_hwp_max() which updates hwp_cap_cached
may run in parallel with the readers of it, annotate all of the
read accesses to it with READ_ONCE().

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.

Some code in drivers/acpi/sleep.c (which is regarded as a generic

user of it) anyway for a long time.

Hi,
This series addresses some enumeration ordering issues by using information
from _DEP to defer the enumeration of devices that are likely to depend on
operation region (OpRegion) handlers supplied by the drivers of other
devices.
This allows the OpRegion suppliers to be probed and start
From: Rafael J. Wysocki
In some cases ACPI control methods used during device enumeration
(such as _HID or _STA) may rely on Operation Region handlers
supplied by the drivers of other devices [1]:
An example of this is the Acer Switch 10E SW3-016 model. The _HID
method of the ACPI node
From: Rafael J. Wysocki
Evaluate _DEP before calling acpi_add_single_object() from
acpi_bus_check_add() and do that only for ACPI_BUS_TYPE_DEVICE
objects.
While at it, rename acpi_device_dep_initialize() to
acpi_scan_check_dep(), fix up a memory allocation statement in
that function
From: Rafael J. Wysocki
If there are no devices whose enumeration has been deferred after
the first pass in acpi_bus_scan(), the second pass is not necssary,
so avoid it with the help of a new static variable.

Change the language used through-out to supplier
From: Rafael J. Wysocki
According to Hans, all device objects where the _HID returns
"INT3396" also have a _CID returning "PNP0D80", so the former
need not be present in acpi_ignore_dep_ids[] any more.

When avoiding reduction of the frequency after the target CPU has
been busy since the previous frequency update, adjust the utilization
instead of adjusting the frequency, because doing so is more prudent

Hi,
This is based on the RFC posted a few days ago:
https://lore.kernel.org/linux-pm/1817571.2o5Kk4Ohv2@kreacher/
The majority of the original cover letter still applies, so let me quote it
here:

Instead of passing util and max between functions while computing the
utilization and capacity, store the former in struct sg_cpu (along
with the latter and bw_dl).
This will allow the current utilization value to be compared with the
one obtained previously (which

From: Rafael J. Wysocki
First off, some cpufreq drivers (eg. intel_pstate) can pass hints
beyond the current target frequency to the hardware and there are no
provisions for doing that in the cpufreq framework. In particular,
today the driver has to assume that it should not allow the frequency

The PNP0D80 ("Windows-compatible System Power Management Controller")
device ID is used for identifying the special device object providing
the LPI (Low-power S0 Idle) _DSM interface [1]. That device object
does not supply any operation regions, but it appea

erhead-related concerns. There still are some, but maybe that
doesn't matter in practice.
Also, I kind of expect this to blow up somewhere, but since I have no
examples ready from the top of my head, I think let's try and see, so:
