[Intel-gfx] [PATCH v3 01/11] drm/i915: Add i915 perf infrastructure

2016-08-15 Thread Robert Bragg
Adds base i915 perf infrastructure for Gen performance metrics. This adds a DRM_IOCTL_I915_PERF_OPEN ioctl that takes an array of uint64 properties to configure a stream of metrics and returns a new fd usable with standard VFS system calls including read() to read typed and sized records; ioctl()
