    [PATCH] 2.5.35 perfmon update · c8aa9eb7
    Stéphane Eranian authored
    This patch adds/modifies:
            - fix system-wide in UP mode
            - adds defaults values for all PMC/PMD in the pfm_reg_desc tables
            - adds bitmask of reserved fields for all PMC/PMD in the pfm_reg_desc
              tables
            - on McKinley ensures that reserved fields in PMC keep their initial
              values
            - ia64_reset_pmu() renamed pfm_reset_pmu()
            - pfm_pmu_snapshot() and reset_pmcs[] are gone
            - use pfm_reg_desc for defaults values anywhere it is needed
            - we now reinitialize all PMC to their default value when the kernel
              initializes perfmon on each CPU. That's needed because we have no
              guarantee there are still in the power-up state when kernel gets
              control.
            - /proc/perfmon now shows dcr_pp/pfm_syst_wide for ALL CPUs
            - adds a perfmon_generic.h in case neither CONFIG_ITANIUM nor
              CONFIG_MCKINLEY are defined
