perf trace beautify ioctl: Beautify vhost virtio ioctl's 'cmd' arg Also trying a new approach, using a copy of uapi/linux/vhost.h we auto generate the string tables, then include it in the ioctl cmd beautifier. This way either the KVM developers will add the new commands to the tools/ copy, like is happening with other areas of tools/include/ (bpf.h comes to mind), or we'll be notified when building perf that our copy drifted. E.g., doing syswide tracing grepping for the newly beautified VHOST ioctls: # perf trace -e ioctl 2>&1 | grep VHOST 3873.064 ( 0.099 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_NET_SET_BACKEND, arg: 0x7fff053dffe0) = 0 3873.168 ( 0.019 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_NET_SET_BACKEND, arg: 0x7fff053dffe0) = 0 3873.226 ( 0.006 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_GET_VRING_BASE, arg: 0x7fff053dff60) = 0 3873.244 ( 0.002 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_GET_VRING_BASE, arg: 0x7fff053dff60) = 0 3873.817 ( 0.014 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_SET_VRING_CALL, arg: 0x7fff053dff20) = 0 3873.838 ( 0.004 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_SET_VRING_CALL, arg: 0x7fff053dff20) = 0 4701.372 ( 0.006 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_SET_VRING_CALL, arg: 0x7fff053dfe20) = 0 4701.417 ( 0.007 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_SET_VRING_CALL, arg: 0x7fff053dfe20) = 0 4701.563 ( 0.004 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_SET_FEATURES, arg: 0x7fff053dfe88) = 0 4701.571 ( 0.028 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_SET_MEM_TABLE, arg: 0x563c7c906870) = 0 4701.604 ( 0.003 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_SET_VRING_NUM, arg: 0x7fff053dff00) = 0 4701.609 ( 0.002 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_SET_VRING_BASE, arg: 0x7fff053dff00) = 0 4701.615 ( 0.002 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_SET_VRING_ADDR, arg: 0x7fff053dfe70) = 0 4701.619 ( 0.008 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_SET_VRING_KICK, arg: 0x7fff053dfef0) = 0 4701.634 ( 0.004 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_SET_VRING_NUM, arg: 0x7fff053dff00) = 0 4701.640 ( 0.002 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_SET_VRING_BASE, arg: 0x7fff053dff00) = 0 4701.644 ( 0.002 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_SET_VRING_ADDR, arg: 0x7fff053dfe70) = 0 4701.648 ( 0.009 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_SET_VRING_KICK, arg: 0x7fff053dfef0) = 0 4701.665 ( 0.005 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_NET_SET_BACKEND, arg: 0x7fff053dff80) = 0 4701.672 ( 0.004 ms): qemu-system-x8/21238 ioctl(fd: 27</dev/vhost-net>, cmd: VHOST_NET_SET_BACKEND, arg: 0x7fff053dff80) = 0 ^C '-e ioctl' uses tracepoint filters, in time this will be replaces by eBPF filters hooked at the syscall tracepoints and that "grep VHOST" will also be done with eBPF, right at the kernel, to reduce overhead.

perf beauty: Move uapi/linux/vhost.h copy out of the directory used to build perf It is only used to generate string tables, not to build perf, so move it to the tools/perf/trace/beauty/include/ hierarchy, that is used just for scraping. This is a something that should've have happened, as happened with the linux/socket.h scrapper, do it now as Ian suggested while doing an audit/refactor session in the headers used by perf. No other tools/ living code uses it, just <linux/vhost.h> coming from either 'make install_headers' or from the system /usr/include/ directory.
