remoteproc: meson-mx-ao-arc: Add a driver for the AO ARC remote procesor
Amlogic Meson6, Meson8, Meson8b and Meson8m2 embed an ARC core in the
Always-On (AO) power-domain. This is typically used for waking up the
ARM cores after system suspend.
The configuration is spread across three different registers:
- AO_REMAP_REG0 which must be programmed to zero, it's actual purpose
is unknown. There is a second remap register which is not used in the
vendor kernel (which served as reference for this driver).
- AO_CPU_CNTL is used to start and stop the ARC core.
- AO_SECURE_REG0 in the SECBUS2 register area with unknown purpose.
To boot the ARC core we also need to enable it's gate clock and trigger
a reset.
The actual code for this ARC core can come from an ELF binary, for
example by building the Zephyr RTOS for an ARC EM4 core and then taking
"zephyr.elf" as firmware. This executable does not have any "rsc table"
so we are skipping rproc_elf_load_rsc_table (rproc_ops.parse_fw) and
rproc_elf_find_loaded_rsc_table (rproc_ops.find_loaded_rsc_table).

remoteproc: qcom: q6v5: Use qmp_send to update co-processor load state
The power domains exposed by the AOSS QMP driver control the load state
resources linked to modem, adsp, cdsp remoteprocs. These are used to
notify the Always on Subsystem (AOSS) that a particular co-processor is
up/down. AOSS uses this information to wait for the co-processors to
suspend before starting its sleep sequence.
These co-processors enter low-power modes independent to that of the
application processor and the load state resources linked to them are
expected to remain unaltered across system suspend/resume cycles. To
achieve this behavior lets stop using the power-domains exposed by the
AOSS QMP node and replace them with generic qmp_send interface instead.

dt-bindings: remoteproc: qcom: pas: Add QMP property
The load state power-domain, used by the co-processors to notify the
Always on Subsystem (AOSS) that a particular co-processor is up/down,
suffers from the side-effect of changing states during suspend/resume.
However the co-processors enter low-power modes independent to that of
the application processor and their states are expected to remain
unaltered across system suspend/resume cycles. To achieve this behavior
let's drop the load state power-domain and replace them with the qmp
property for all SoCs supporting low power mode signalling.
Due to the current broken load state implementation, we can afford the
binding breakage that ensues and the remoteproc functionality will remain
the same when using newer kernels with older dtbs.

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.

e4c2f42a4c61a2d632d92a72afa08f00000000/elf.
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 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

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"

This is needed so that we can use 'perf report' on a perf.data with IBS

Merge tag 'arm64-fixes' of git://git./linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
- Limit the linear region to 51-bit when KVM is running in nVHE mode.
Otherwise, depending on the placement of the ID map, kernel-VA to
hyp-VA translations may produce addresses that either conflict with
other HYP mappings or generate addresses outside of the 52-bit
addressable range.
- Instruct kmemleak not to scan the memory reserved for kdump as this
range is removed from the kernel linear map and therefore not
accessible.
