Previous discussion can be found at https://lore.kernel.org/dri-devel/dqhnxhgho6spfh7xhw6yvs2iiqeqzeg63e6jqqpw2g7gkrfphn@dojsixyl4esv/ Changelog: v4: - Fixed wrong assignment location for frequency values in Panthor's devfreq - Removed the last two commits about registering size of internal BO's - Rearranged patch series so that sysfs knob is done last and all the previous time sampling and fdinfo show dependencies are already in place v3: - Fixed some nits and removed useless bounds check in panthor_sched.c - Added support for sysfs profiling knob and optional job accounting - Added new patches for calculating size of internal BO's 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.
