#yocto -kernel startup of devices/platform/amba/ffa00000.perf-monitor #yocto
Monsees, Steven C (US)
I am running with zeus…, during kernel startup I see perf-monitors setup
[ 3.564635] xilinx-axipmon ffa00000.perf-monitor: Probed Xilinx APM [ 3.571139] xilinx-axipmon fd0b0000.perf-monitor: Probed Xilinx APM [ 3.577571] xilinx-axipmon fd490000.perf-monitor: Probed Xilinx APM [ 3.583987] xilinx-axipmon ffa10000.perf-monitor: Probed Xilinx APM
Are these are tied to uio0 thru uio3 ? Can someone tell me what recipe initializes and brings these in ? Is it possible to delay their initialization/startup ? (I would like to have them come into play after I setup the uio_fpga interrupt…) root@cvpx-default ls -la /sys/class/uio total 0 drwxr-xr-x 2 root root 0 Jan 1 1970 . drwxr-xr-x 49 root root 0 Jan 1 1970 .. lrwxrwxrwx 1 root root 0 Jan 1 1970 uio0 -> ../../devices/platform/amba/ffa00000.perf-monitor/uio/uio0 lrwxrwxrwx 1 root root 0 Jan 1 1970 uio1 -> ../../devices/platform/amba/fd0b0000.perf-monitor/uio/uio1 lrwxrwxrwx 1 root root 0 Jan 1 1970 uio2 -> ../../devices/platform/amba/fd490000.perf-monitor/uio/uio2 lrwxrwxrwx 1 root root 0 Jan 1 1970 uio3 -> ../../devices/platform/amba/ffa10000.perf-monitor/uio/uio3 lrwxrwxrwx 1 root root 0 Jul 28 17:36 uio4 -> ../../devices/uio_fpga/uio/uio4 root@cvpx-default
