FEAT_SPEv1p2 (optional from Armv8.6) adds a discard mode that allows all
SPE data to be discarded rather than written to memory. Add a format
bit for this mode.
If the mode isn't supported, the format bit isn't published and attempts
to use it will result in -EOPNOTSUPP. Allocating an aux buffer is still
allowed even though it won't be written to so that old tools continue to
work, but updated tools can choose to skip this step.

For PMUs with no association, the hisi_pmu->on_cpu is initialized
according to the NUMA locality but use a wrong CPU for the interrupt
affinity. The CPU selected from cpumask_local_spread() can be different
from the CPU by the cpuhp callback. Fix this by setting the IRQ affinity
to hisi_pmu->on_cpu.

The imx93 is the first supported DDR PMU that supports read transaction,
write transaction and read beats events which corresponding respecitively
to counter 2, 3 and 4.
However, transaction-based AXI match has low accuracy when get total bits
compared to beats-based. And imx93 doesn't assign AXI_ID to each master.
So axi filter is not used widely on imx93. This could be regards as AXI
filter version 1.
To improve the AXI filter capability, imx95 supports 1 read beats and 3
write beats event which corresponding respecitively to counter 2-5. imx95
also detailed AXI_ID allocation so that most of the master could be count
individually. This could be regards as AXI filter version 2.
This will introduce AXI filter version to refactor the driver and support
better extension, such as coming imx943. This is also a potential fix on
imx91 when configure axi filter.

The group validation logic still somewhat assumes the original CMN-600
case of events counting globally, such that if one tries to group 9
events where the first 8 target a single DTC domain, the 9th will be
rejected because *a* DTC domain is full, even though it might only
target other non-overlapping domains and thus still be schedulable.
Improve matters by only counting the DTCs that the new event actually
needs (as arm_cmn_val_add_event() was already clever enough to do).

PCI Vendor-Specific (VSEC) Capabilities are defined by each vendor.
Devices from different vendors may advertise a VSEC Capability with the DWC
RAS DES functionality, but the vendors may assign different VSEC IDs.
Search for the DWC RAS DES Capability using the VSEC ID and VSEC Rev
chosen by the vendor.
This does not fix a current problem because Alibaba, Ampere, and Qualcomm
all assigned the same VSEC ID and VSEC Rev for the DWC RAS DES Capability.
The potential issue is that we may add support for a device from another
vendor, where the vendor has already assigned DWC_PCIE_VSEC_RAS_DES_ID
(0x02) for an unrelated VSEC. In that event, dwc_pcie_des_cap() would find
the unrelated VSEC and mistakenly assume it was a DWC RAS DES Capability.

Although the event of the uncore PMU can only be opened on a single
CPU, some PMU does have the affinity on a range of CPUs. For example
the L3C PMU is associated to the CPUs sharing the L3T it monitors.
Users may infer this affinity by the PMU name which may have SCCL ID
and CCL ID encoded (for L3C etc), but it's not that straightforward.
So export this information by adding an "associated_cpus" sysfs
attribute then user can get this directly.

- format: bitmask in perf_event_attr::config[012] of corresponding
attribute
- event: events name and corresponding event code
- cpumask: range of CPUs the events can be opened on
- identifier: the version of this PMU
Different types of PMU have different implementations of the "format"

and "identifier". Thus we can move cpumask and identifier to the
hisi_uncore_pmu framework and drivers can use the generic

There are two type of PMUs supported currently:
1) PMUs locate on SCCL (Super CPU Cluster [1]), associated with certain
CCL (CPU cluster [1])(e.g. L3C PMU) or not (e.g. DDRC PMU)
2) PMUs locate on the SICL (Super IO Cluster [1]), which has no
association with certain CPU topology (e.g. CPA PMU)
Currently the associated CPUs of the PMU is detected in the cpuhp online
callback as below:
- for type 1) the CPUs match PMU's sccl_id and ccl_id
- for type 2) PMU's sccl_id is -1 and all online CPUs will be associated
Since uncore PMUs are not bound to certain CPU context and event could be
counting started by any online CPU, the associated CPUs are just a
preference. Below disadvantages are observed in current implementation:
- the PMU cannot be used if its associated CPUs are offline
- SICL PMUs are associated to all the online CPUs implicitly without
the consideration of locality
So refactor the way we detect the associated CPUs in below aspects:
- add a clear definition of hisi_pmu::associated_cpus
- initialize hisi_pmu::on_cpu based on locality if no associated CPU
found, otherwise update it from associated CPUs
- drop the detection with a sccl_id of -1 for SICL PMUs

Each TAD provides eight 64-bit counters for monitoring
cache behavior.The driver always configures the same counter for
all the TADs. The user would end up effectively reserving one of
eight counters in every TAD to look across all TADs.
The occurrences of events are aggregated and presented to the user
at the end of running the workload. The driver does not provide a
way for the user to partition TADs so that different TADs are used for
different applications.
The performance events reflect various internal or interface activities.
By combining the values from multiple performance counters, cache
performance can be measured in terms such as: cache miss rate, cache
allocations, interface retry rate, internal resource occupancy, etc.
Each supported counter's event and formatting information is exposed
to sysfs at /sys/devices/tad/. Use perf tool stat command to measure
the pmu events. For instance:
perf stat -e tad_hit_ltg,tad_hit_dtg <workload>

Since commit 13b25489b6 ("kbuild: change working directory to external
module directory with M="), the Debian package build fails if a relative
path is specified with the O= option.
$ make O=build bindeb-pkg
[ snip ]
dpkg-deb: building package 'linux-image-6.13.0-rc1' in '../linux-image-6.13.0-rc1_6.13.0-rc1-6_amd64.deb'.

make[6]: Entering directory '/home/masahiro/linux/build'
/home/masahiro/linux/Makefile:190: *** specified kernel directory "build" does not exist. Stop.
This occurs because the sub_make_done flag is cleared, even though the
working directory is already in the output directory.
Passing KBUILD_OUTPUT=. resolves the issue.

The compiler can fully inline the actual handler function of an interrupt
entry into the .irqentry.text entry point. If such a function contains an
access which has an exception table entry, modpost complains about a
section mismatch:
WARNING: vmlinux.o(__ex_table+0x447c): Section mismatch in reference ...
The relocation at __ex_table+0x447c references section ".irqentry.text"
which is not in the list of authorized sections.
Add .irqentry.text to OTHER_SECTIONS to cure the issue.

configuration is rejected and kernel gracefully falls back to dummy NUMA.

Pull memblock fixes from Mike Rapoport:
"Restore check for node validity in arch_numa.
The rework of NUMA initialization in arch_numa dropped a check that
refused to accept configurations with invalid node IDs.
Restore that check to ensure that when firmware passes invalid nodes,
such configuration is rejected and kernel gracefully falls back to
dummy NUMA"
* tag 'fixes-2024-12-06' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock:
arch_numa: Restore nid checks before registering a memblock with a node
memblock: allow zero threshold in validate_numa_converage()
- amdgu: mostly display fixes + jpeg vcn 1.0, sriov, dcn4.0 resume
