tools headers uapi: Sync linux/usbdevice_fs.h with the kernel sources
To pick up the changes from: 4ed3350539aa ("USB: usbfs: Add a capability flag for runtime suspend") 7794f486ed0b ("usbfs: Add ioctls for runtime power management") This triggers these changes in the kernel sources, automagically supporting these new ioctls in the 'perf trace' beautifiers. Soon this will be used in things like filter expressions for tracepoints in 'perf record', 'perf trace', 'perf top', i.e. filter expressions will do a lookup to turn things like USBDEVFS_WAIT_FOR_RESUME into _IO('U', 35) before associating the tracepoint expression to tracepoint perf event. $ tools/perf/trace/beauty/usbdevfs_ioctl.sh > before $ cp include/uapi/linux/usbdevice_fs.h tools/include/uapi/linux/usbdevice_fs.h $ git diff diff --git a/tools/include/uapi/linux/usbdevice_fs.h b/tools/include/uapi/linux/usbdevice_fs.h index 78efe870c2b7..cf525cddeb94 100644 --- a/tools/include/uapi/linux/usbdevice_fs.h +++ b/tools/include/uapi/linux/usbdevice_fs.h @@ -158,6 +158,7 @@ struct usbdevfs_hub_portinfo { #define USBDEVFS_CAP_MMAP 0x20 #define USBDEVFS_CAP_DROP_PRIVILEGES 0x40 #define USBDEVFS_CAP_CONNINFO_EX 0x80 +#define USBDEVFS_CAP_SUSPEND 0x100 /* USBDEVFS_DISCONNECT_CLAIM flags & struct */ @@ -223,5 +224,8 @@ struct usbdevfs_streams { * extending size of the data returned. */ #define USBDEVFS_CONNINFO_EX(len) _IOC(_IOC_READ, 'U', 32, len) +#define USBDEVFS_FORBID_SUSPEND _IO('U', 33) +#define USBDEVFS_ALLOW_SUSPEND _IO('U', 34) +#define USBDEVFS_WAIT_FOR_RESUME _IO('U', 35) #endif /* _UAPI_LINUX_USBDEVICE_FS_H */ $ tools/perf/trace/beauty/usbdevfs_ioctl.sh > after $ diff -u before after --- before 2019-09-27 11:41:50.634867620 -0300 +++ after 2019-09-27 11:42:07.453102978 -0300 @@ -24,6 +24,9 @@ [30] = "DROP_PRIVILEGES", [31] = "GET_SPEED", [32] = "CONNINFO_EX", + [33] = "FORBID_SUSPEND", + [34] = "ALLOW_SUSPEND", + [35] = "WAIT_FOR_RESUME", [3] = "RESETEP", [4] = "SETINTERFACE", [5] = "SETCONFIGURATION", $ This addresses the following perf build warning: Warning: Kernel ABI header at 'tools/include/uapi/linux/usbdevice_fs.h' differs from latest version at 'include/uapi/linux/usbdevice_fs.h' diff -u tools/include/uapi/linux/usbdevice_fs.h include/uapi/linux/usbdevice_fs.h Cc: Alan Stern <stern@rowland.harvard.edu> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Brendan Gregg <brendan.d.gregg@gmail.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Luis Cláudio Gonçalves <lclaudio@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lkml.kernel.org/n/tip-x1rb109b9nfi7pukota82xhj@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
