Hi, it seems to work with
perf stat -a -e "uncore_mbox_0/event=bbox_cmds_read/" /bin/ls These counter are also shown in: $ ls /sys/bus/event_source/devices/uncore_mbox_*/events /sys/bus/event_source/devices/uncore_mbox_0/events: bbox_cmds_read bbox_cmds_write /sys/bus/event_source/devices/uncore_mbox_1/events: bbox_cmds_read bbox_cmds_write [hollmann@inwest stream]$ ls /sys/bus/event_source/devices/uncore_mbox_*/events /sys/bus/event_source/devices/uncore_mbox_0/events: bbox_cmds_read bbox_cmds_write /sys/bus/event_source/devices/uncore_mbox_1/events: bbox_cmds_read bbox_cmds_write Other counters are in: $ ls /sys/bus/event_source/devices/uncore_rbox_*/events /sys/bus/event_source/devices/uncore_rbox_0/events: qpi0_date_response qpi0_flit_send qpi0_idle_filt qpi1_date_response qpi1_filt_send qpi1_idle_filt /sys/bus/event_source/devices/uncore_rbox_1/events: qpi0_date_response qpi0_flit_send qpi0_idle_filt qpi1_date_response qpi1_filt_send qpi1_idle_filt Maye this helps somebody else. 2013/12/19 Andreas Hollmann <andreas.hollm...@gmail.com>: > Hi, > > I have a problem to read the IMC uncore counters (other uncore > counters do also not work). > > -- > perf stat -a -e "uncore_imc_0/event=0xff,umask=0x00/" /bin/ls > invalid or unsupported event: 'uncore_imc_0/event=0xff,umask=0x00/' > -- > > They are not even shown under /sys/... > > Is there uncore support for the Westmere EX in the Linux Kernel? > > If there is support, do I have a BIOS issue that these > counters/devices are not exported and > visible in the kernel?
