platform/x86: amd-pmc: Fix compilation when CONFIG_DEBUGFS is disabled
The amd_pmc_get_smu_version() and amd_pmc_idlemask_read() functions are
used in the probe / suspend/resume code, so they are also used when
CONFIG_DEBUGFS is disabled, move them outside of the #ifdef CONFIG_DEBUGFS
block.
Note this purely moves the code to above the #ifdef CONFIG_DEBUGFS,
the code is completely unchanged.

platform/x86: hp-wmi: add support for omen laptops
This patch adds support for HP Omen laptops.
It adds support for most things that can be controlled via the
Windows Omen Command Center application.
- Fan speed monitoring through hwmon
- Platform Profile support (cool, balanced, performance)
- Max fan speed function toggle
Also exposes the existing HDD temperature through hwmon since
this driver didn't use hwmon before this patch.
This patch has been tested on a 2020 HP Omen 15 (AMD) 15-en0023dx.
- V1
Initial Patch
- V2
Use standard hwmon ABI attributes
Add existing non-standard "hddtemp" to hwmon
- V3
Fix overflow issue in "hp_wmi_get_fan_speed"
Map max fan speed value back to hwmon values on read
Code style fixes
Fix issue with returning values from "hp_wmi_hwmon_read",
the value to return should be written to val and not just
returned from the function
- V4
Use DMI Board names to detect if a device should use the omen
specific thermal profile method.
Select HWMON instead of depending on it.
Code style fixes.
Replace some error codes with more specific/meaningful ones.
Remove the HDD temperature from HWMON since we don't know what
unit it's expressed in.
Handle error from hp_wmi_hwmon_init
- V5
Handle possible NULL from dmi_get_system_info()
Use match_string function instead of manually checking
Directly use is_omen_thermal_profile() without the static
variable.

platform/x86: amd-pmc: Increase the response register timeout
There have been reports of approximately a 0.9%-1.7% failure rate in SMU
communication timeouts with s0i3 entry on some OEM designs. Currently
the design in amd-pmc is to try every 100us for up to 20ms.
However the GPU driver which also communicates with the SMU using a
mailbox register which the driver polls every 1us for up to 2000ms.
In the GPU driver this was increased by commit
055162645a40 ("drm/amd/pm:
increase time out value when sending msg to SMU")
Increase the maximum timeout used by amd-pmc to 2000ms to match this
behavior. This has been shown to improve the stability for machines
that randomly have failures.

perf tools: Allow build-id with trailing zeros
Currently perf saves a build-id with size but old versions assumes the
size of 20. In case the build-id is less than 20 (like for MD5), it'd
fill the rest with 0s.
I saw a problem when old version of perf record saved a binary in the
build-id cache and new version of perf reads the data. The symbols
should be read from the build-id cache (as the path no longer has the
same binary) but it failed due to mismatch in the build-id.

The build-id event in the data has 20 byte build-ids, but it saw a
different size (16) when it reads the build-id of the elf file in the
build-id cache.

perf report: Add support to print a textual representation of IBS raw sample data
Perf records IBS (Instruction Based Sampling) extra sample data when
'perf record --raw-samples' is used with an IBS-compatible event, on a
machine that supports IBS. IBS support is indicated in
CPUID_Fn80000001_ECX bit #10.
Up until now, users have been able to see the extra sample data solely
in raw hex format using 'perf report --dump-raw-trace'. From there,
users could decode the data either manually, or by using an external
script.
Enable the built-in 'perf report --dump-raw-trace' to do the decoding of
the extra sample data bits, so manual or external script decoding isn't
necessary.

cc1: all warnings being treated as errors
As that %2d won't limit the number of chars to 2, just state that 2 is
the minimal width:
$ cat printf.c
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
char bf[64];
int len = snprintf(bf, sizeof(bf), "%2d", atoi(argv[1]));
printf("strlen(%s): %u\n", bf, len);
return 0;
}
$ ./printf 1
strlen( 1): 2
$ ./printf 12
strlen(12): 2
$ ./printf 123
strlen(123): 3
$ ./printf 1234
strlen(1234): 4
$ ./printf 12345
strlen(12345): 5
$ ./printf 123456
strlen(123456): 6
$
And since we probably don't want that output to be truncated, just
assume the worst case, as the compiler did, and add a few more chars to
that buffer.
Also use sizeof(var) instead of sizeof(dup-of-wanted-format-string) to
avoid bugs when changing one but not the other.
I also had to change this:
-#include <asm/amd-ibs.h>
+#include "../../arch/x86/include/asm/amd-ibs.h"
To make it build on other architectures, just like intel-pt does.
