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

Ilkka Koskinen (4):
  perf: arm_cspmu: Split 64-bit write to 32-bit writes
  perf: arm_cspmu: Support implementation specific filters
  perf: arm_cspmu: Support implementation specific validation
  perf: arm_cspmu: ampere_cspmu: Add support for Ampere SoC PMU
