    perf trace beauty: Default header_dir to cwd to work without parms · 61b229ce
    Arnaldo Carvalho de Melo authored
    Useful when checking the effects of header synchs for the files it uses
    as a input to generate string tables, in retrospect this is how it
    should've been done from day 1, not requiring the header_dir to be set
    on the Makefile, will change everything later, so that the only parm,
    common to all generators will be $(srctree) and $(beauty_outdir).
    
    So, to see what it generates, just call it without any parameters:
    
      $ tools/perf/trace/beauty/vhost_virtio_ioctl.sh
      static const char *vhost_virtio_ioctl_cmds[] = {
    	[0x00] = "SET_FEATURES",
    	[0x01] = "SET_OWNER",
    	[0x02] = "RESET_OWNER",
    	[0x03] = "SET_MEM_TABLE",
    	[0x04] = "SET_LOG_BASE",
    	[0x07] = "SET_LOG_FD",
    	[0x10] = "SET_VRING_NUM",
    	[0x11] = "SET_VRING_ADDR",
    	[0x12] = "SET_VRING_BASE",
    	[0x13] = "SET_VRING_ENDIAN",
    	[0x14] = "GET_VRING_ENDIAN",
    	[0x20] = "SET_VRING_KICK",
    	[0x21] = "SET_VRING_CALL",
    	[0x22] = "SET_VRING_ERR",
    	[0x23] = "SET_VRING_BUSYLOOP_TIMEOUT",
    	[0x24] = "GET_VRING_BUSYLOOP_TIMEOUT",
    	[0x30] = "NET_SET_BACKEND",
    	[0x40] = "SCSI_SET_ENDPOINT",
    	[0x41] = "SCSI_CLEAR_ENDPOINT",
    	[0x42] = "SCSI_GET_ABI_VERSION",
    	[0x43] = "SCSI_SET_EVENTS_MISSED",
    	[0x44] = "SCSI_GET_EVENTS_MISSED",
    	[0x60] = "VSOCK_SET_GUEST_CID",
    	[0x61] = "VSOCK_SET_RUNNING",
      };
      static const char *vhost_virtio_ioctl_read_cmds[] = {
    	[0x00] = "GET_FEATURES",
    	[0x12] = "GET_VRING_BASE",
      };
      $
    
    Or:
    
      $ tools/perf/trace/beauty/sndrv_pcm_ioctl.sh
      static const char *sndrv_pcm_ioctl_cmds[] = {
    	[0x00] = "PVERSION",
    	[0x01] = "INFO",
    	[0x02] = "TSTAMP",
    	[0x03] = "TTSTAMP",
    	[0x04] = "USER_PVERSION",
    	[0x10] = "HW_REFINE",
    	[0x11] = "HW_PARAMS",
    	[0x12] = "HW_FREE",
    	[0x13] = "SW_PARAMS",
    	[0x20] = "STATUS",
    	[0x21] = "DELAY",
    	[0x22] = "HWSYNC",
    	[0x23] = "SYNC_PTR",
    	[0x24] = "STATUS_EXT",
    	[0x32] = "CHANNEL_INFO",
    	[0x40] = "PREPARE",
    	[0x41] = "RESET",
    	[0x42] = "START",
    	[0x43] = "DROP",
    	[0x44] = "DRAIN",
    	[0x45] = "PAUSE",
    	[0x46] = "REWIND",
    	[0x47] = "RESUME",
    	[0x48] = "XRUN",
    	[0x49] = "FORWARD",
    	[0x50] = "WRITEI_FRAMES",
    	[0x51] = "READI_FRAMES",
    	[0x52] = "WRITEN_FRAMES",
    	[0x53] = "READN_FRAMES",
    	[0x60] = "LINK",
    	[0x61] = "UNLINK",
      };
      $
    
    Etc.
