Subject: [PATCH v4 0/2] Mesh PMU: Add tertiary match group support
v4: * No changes, only rebased on top of v6.10-rc4
v3:
* Replaced wp_cfg in arm_cmn_hw_event with wp_idx that keeps
track, whether the event uses 0 or 1 index for the given direction
* Cleaned and simplified allocation/claiming of wp config
* arm_cmn_val_add_event() can't and won't fail anymore
* Separated wp_combine from wp[] in event validation phase
* use memset()/sizeof() when clearing an event
* Still kept wp config allocator in separate functions - at least
for now
* https://lore.kernel.org/all/20240329013215.169345-1-ilkka@os.amperecomputing.com/
v2:
* Wp config registers are allocated on node basis, instead
of using the same one globally
* Use bitmap in the event structure to keep track on the
wp config registers assigned to the specific event.
* The bitmap tracks only either UP (wp conf 0&1) or DOWN
(wp conf 2&3) registers.
* Dropped the second patch
("The patch set v2 is now in the internal mailing list")
as perf/sysfs doesn't really support items with the same
name even if visibility would handle them.
* Addressed a bunch of other comments by the author
* https://lore.kernel.org/all/20240307230929.6233-2-ilkka@os.amperecomputing.com/
v1:
* https://lore.kernel.org/all/20240126221215.1537377-1-ilkka@os.amperecomputing.com/
