This is the extension of AXI ID filter. Filter is defined with 2 configuration registers per counter 1-3 (counter 0 is not used for filtering and lacks these registers). * Counter N MASK COMP register - AXI_ID and AXI_MASKING. * Counter N MUX CNTL register - AXI CHANNEL and AXI PORT. -- 0: address channel -- 1: data channel This filter is exposed to userspace as an additional (channel, port) pair. The definition of axi_channel is inverted in userspace, and it will be reverted in driver automatically. AXI filter of Perf Monitor in DDR Subsystem, only a single port0 exist, so axi_port is reserved which should be 0. e.g. perf stat -a -e imx8_ddr0/axid-read,axi_mask=0xMMMM,axi_id=0xDDDD,axi_channel=0xH/ cmd perf stat -a -e imx8_ddr0/axid-write,axi_mask=0xMMMM,axi_id=0xDDDD,axi_channel=0xH/ cmd Signed-off-by: Xu Yang <xu.yang_2@nxp.com> Reviewed-by: Frank Li <Frank.Li@nxp.com> Link: https://lore.kernel.org/r/20231120093317.2652866-1-xu.yang_2@nxp.com Signed-off-by: Will Deacon <will@kernel.org> |
