On the other hand there is arch/mips/kernel/perf_event.c ... So maybe "perf" is supported on MIPS? Is ther linux-tools / linux-utild package for OpenWrt? -- Rafał _______________________________________________ openwrt-devel mailing list [email protected] https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
