Subject: [PATCH 0/4] perf: ampere: Add support for Ampere SoC PMUs
Date: Wed, 21 Jun 2023 18:11:37 -0700 [thread overview]
Message-ID: <20230622011141.328029-1-ilkka@os.amperecomputing.com> (raw)
Changes since v3:
* use_64b_counter_reg => has_atomic_dword (patch 1/4)
* Removed the unnecessary hook for group validation (patch 3/4)
* Added group config validation to ampere_cspmu_validate_event() (patch 4/4)
* Rebased the patchset
Changes since v2:
* Changed to use supports_64bits_atomics() and replaced the split writes
with lo_hi_writeq()
* Added implementation specific group validation to patch 3
* Dropped shared interrupt patch
* Removed unnecessary filter_enable parameter from ampere module
* Added group validation to ampere module
Changes since v1:
* Rather than creating a completely new driver, implemented as a submodule
of Arm CoreSight PMU driver
* Fixed shared filter handling
