drm/i915: Add tracepoints By adding tracepoint equivalents for WATCH_BUF/EXEC we are able to monitor the lifetimes of objects, requests and significant events. These events can then be probed using the tracing frameworks, such as systemtap and, in particular, perf. For example to record the stack trace for every GPU stall during a run, use $ perf record -e i915:i915_gem_request_wait_begin -c 1 -g And $ perf report to view the results.
