platform/x86: msi-laptop: Fix old-ec check for backlight registering
Commit
2cc6c717799f ("msi-laptop: Port to new backlight interface
selection API") replaced this check:
if (!quirks->old_ec_model || acpi_video_backlight_support())
pr_info("Brightness ignored, ...");
else
do_register();
With:
if (quirks->old_ec_model ||
acpi_video_get_backlight_type() == acpi_backlight_vendor)
do_register();
But since the do_register() part was part of the else branch, the entire
condition should be inverted. So not only the 2 statements on either
side of the || should be inverted, but the || itself should be replaced
with a &&.
In practice this has likely not been an issue because the new-ec models
(old_ec_model==false) likely all support ACPI video backlight control,
making acpi_video_get_backlight_type() return acpi_backlight_video
turning the second part of the || also false when old_ec_model == false.

platform/x86/amd/pmf: Handle AMT and CQL events for Auto mode
The transition to auto-mode happens when the PMF driver receives
AMT (Auto Mode transition) event. transition logic will reside in the
PMF driver but the events would come from other supported drivers[1].
The thermal parameters would vary between when a performance "on-lap" mode
is detected and versus when not. The CQL event would get triggered from
other drivers, so that PMF driver would adjust the system thermal config
based on the ACPI inputs.
OEMs can control whether or not to enable AMT or CQL via other supported
drivers[1] but the actual transition logic resides in the AMD PMF driver.
When an AMT event is received the automatic mode transition RAPL algorithm
will run. When a CQL event is received an performance "on-lap" mode will
be enabled and thermal parameters will be adjusted accordingly.

platform/x86/amd/pmf: Add support for Auto mode feature
This feature has 3 modes quiet, balanced, performance
The objective of this feature is to track the moving average of system
power over the time period specified and switch to the subsequent mode.
In order to do this, PMF driver will get the moving average of APU power
from PMFW and power threshold, time constants, system config parameters
from OEM inputs.
System power as read by PMF driver from PMFW is the filtered value over
the sampling window. Every sampling window, moving average of system power
is computed. At the end of the monitoring window, the moving average is
compared against the threshold for mode switch for decision making.
With AMD managing the system config limits, any mode switch within
auto-mode will result in limits of fPPT/sPPT/STAPM or STT being scaled
down.
When "auto mode" is enabled, the static slider control remains out of
the PMF driver, so the platform_profile registration would not
happen in PMF driver.
The transition to auto-mode only happens when the APMF fn5 is enabled
in BIOS, platform_profile set to "balanced" and a AMT
(Auto Mode transition) is received.

afs: Enable multipage folio support
Enable multipage folio support for the afs filesystem.
Support has already been implemented in netfslib, fscache and cachefiles
and in most of afs, but I've waited for Matthew Wilcox's latest folio
changes.
Note that it does require a change to afs_write_begin() to return the
correct subpage. This is a "temporary" change as we're working on
getting rid of the need for ->write_begin() and ->write_end()
completely, at least as far as network filesystems are concerned - but
it doesn't prevent afs from making use of the capability.

perf test: Refactor shell tests allowing subdirs
This is a prelude to adding more tests to shell tests and in order to
support putting those tests into subdirectories, I need to change the
test code that scans/finds and runs them.
To support subdirs I have to recurse so it's time to refactor the code
to allow this and centralize the shell script finding into one location
and only one single scan that builds a list of all the found tests in
memory instead of it being duplicated in 3 places.
This code also optimizes things like knowing the max width of desciption
strings (as we can do that while we scan instead of a whole new pass of
opening files).
It also more cleanly filters scripts to see only *.sh files thus
skipping random other files in directories like *~ backup files, other
random junk/data files that may appear and the scripts must be
executable to make the cut (this ensures the script lib dir is not seen
as scripts to run).
This avoids perf test running previous older versions of test scripts
that are editor backup files as well as skipping perf.data files that
may appear and so on.

perf jevents: Fold strings optimization
If a shorter string ends a longer string then the shorter string may
reuse the longer string at an offset. For example, on x86 the event
arith.cycles_div_busy and cycles_div_busy can be folded, even though
they have difference names the strings are identical after 6
characters. cycles_div_busy can reuse the arith.cycles_div_busy string
at an offset of 6.
In pmu-events.c this looks like the following where the 'also:' lists
folded strings:
/* offset=177541 */ "arith.cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000" /* also: cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000 */
As jevents.py combines multiple strings for an event into a larger
string, the amount of folding is minimal as all parts of the event must
align. Other organizations can benefit more from folding, but lose space
by say recording more offsets.

perf jevents: Compress the pmu_events_table
The pmu_events array requires 15 pointers per entry which in position
independent code need relocating. Change the array to be an array of
offsets within a big C string. Only the offset of the first variable is
required, subsequent variables are stored in order after the \0
terminator (requiring a byte per variable rather than 4 bytes per
offset).
The file size savings are:
no jevents - the same 19,788,464bytes
x86 jevents - ~16.7% file size saving 23,744,288bytes vs 28,502,632bytes
all jevents - ~19.5% file size saving 24,469,056bytes vs 30,379,920bytes
default build options plus NO_LIBBFD=1.
For example, the x86 build savings come from .rela.dyn and
.data.rel.ro becoming smaller by 3,157,032bytes and 3,042,016bytes
respectively. .rodata increases by 1,432,448bytes, giving an overall
4,766,600bytes saving.
To make metric strings more shareable, the topic is changed from say
'skx metrics' to just 'metrics'.
To try to help with the memory layout the pmu_events are ordered as used
by perf qsort comparator functions.
