This patch series enables userspace utilities like gputop and nvtop to query a render context's fdinfo file and figure out rates of engine and memory utilisation. Changelog: v2: - Split original first patch in two, one for FW CS cycle and timestamp calculations and job accounting memory management, and a second one that enables fdinfo. - Moved NUM_INSTRS_PER_SLOT to the file prelude - Removed nelem variable from the group's struct definition. - Precompute size of group's syncobj BO to avoid code duplication. - Some minor nits.
