[libc-commits] [PATCH] D153388: [libc] Add basic utility support for timing functions on the GPU

[Jon Chesterfield via Phabricator via libc-commits]

JonChesterfield added a comment.

Is that the right basis set? I wonder if we want cycle_count, frequency, width as the controls. It seems like PTX wants to do ns granularity which is useful and GCN needs the loader to write to a global to get the frequency value, and the type wraparound could be anywhere from 20 to 64
