perf/urgent fixes:
- Show group details on the title line in the annotate browser and 'perf annotate --stdio2' output, so that the per-event columns can have headers (Arnaldo Carvalho de Melo) - Fixup vertical line separating metrics from instructions and cleaning unused lines at the bottom, both in the annotate TUI browser (Arnaldo Carvalho de Melo) - Remove duplicated 'samples' in lost samples warning in 'perf report' (Arnaldo Carvalho de Melo) - Synchronize i915_drm.h, silencing the perf build process, automagically adding support for the new DRM_I915_QUERY ioctl (Arnaldo Carvalho de Melo) - Make auxtrace_queues__add_buffer() allocate struct buffer, from a patchkit already applied (Adrian Hunter) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEELb9bqkb7Te0zijNb1lAW81NSqkAFAlrHVT0ACgkQ1lAW81NS qkC+gRAApp4gb5bVnZJZRfZgkxjiMjIpcoHKepPt44ZgHiNFOJllBhM0QpTMrZ1Y zLjENKdRYmx3T8Oj+KbIHBlSRH9gqMh4vkEF75QhWQXUw6QuB43ZU/zVbulf8Lwb D7T+9h66bJTEhWKAIYb73rQeBPWu6UpP42yXLGiAYd8Wj4NAseYdqfO1W+kC9Niv 7tmT5ld69Jba8I8rMr0dKhi5GiK9Gj5aWDGlGJ1uefil/jwSR3V0oA32Xv84hfop qgbHdc+b/2M04AdFOKbHcMLspKxkZE63Jt+dVkZHWeXfJ/hctwsGbQYEbaZ1Eme2 FDPIGBWq2Ylp09564QwmiAPWG9LVsBa9ipOGt4ZRLP6YZK6e5N1utR0jlgDfLNrD ZmJIE88zHCL6yBmeNwdNUVTuJtznshUeMJaI6FTYwUA5ZWdrF8Es3AqHPLDzsRjt 6QxX7U+DjW9fdzpY23yOc9+Z0z8+2zGVdyEmJlLjENH6Cmyo8sc+PHqhyQi5tK2g xx8cMzGfucrBQdmX0QB/BXjhBn0KkJz/n5YZ2F50RpsZr0MnY1iBHjQF6pcqXvir GKpJLas4K418iXhI+1rncAXxP4RTRduw0BL2urwHWZB9QeFjnZ5XyXFpKCI10flP VDHy5otq3k+tWl2Hb7s/vafZfA+oVyO/KKcHuABIVR9uQGdJSIE= =DzpH -----END PGP SIGNATURE----- Merge tag 'perf-urgent-for-mingo-4.17-20180406' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent Pull perf/urgent fixes from Arnaldo Carvalho de Melo: - Show group details on the title line in the annotate browser and 'perf annotate --stdio2' output, so that the per-event columns can have headers (Arnaldo Carvalho de Melo) - Fixup vertical line separating metrics from instructions and cleaning unused lines at the bottom, both in the annotate TUI browser (Arnaldo Carvalho de Melo) - Remove duplicated 'samples' in lost samples warning in 'perf report' (Arnaldo Carvalho de Melo) - Synchronize i915_drm.h, silencing the perf build process, automagically adding support for the new DRM_I915_QUERY ioctl (Arnaldo Carvalho de Melo) - Make auxtrace_queues__add_buffer() allocate struct buffer, from a patchkit already applied (Adrian Hunter) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
