Subject: [PATCH 0/3] Support discontinuous PMU counters
Date: Tue,  3 Oct 2023 13:49:34 +0100	[thread overview]
Message-ID: <20231003125107.34859-1-rbradford@rivosinc.com> (raw)

Currently the available PMU counters start at HPM3 and run through to
the number specified by the "pmu-num" property. There is no
requirement in the specification that the available counters be
continously numbered. This series add suppport for specifying a
discountinuous range of counters though a "pmu-mask" property.

  target/riscv: Propagate error from PMU setup

  target/riscv: Don't assume PMU counters are continuous
