version 1:
- Initial submission
With the first patch, a short summary about the encoding operation is
unconditionnaly printed at each instance closing:
- information about the stream (format, profile, level, resolution)
- performance information (number of encoded frames, maximum framerate)
- potential (system, encoding...) errors
With the second patch, 4 static debugfs entries are created to dump:
- the device-related information ("st-hva/device")
- the list of registered encoders ("st-hva/encoders")
- the current values of the hva registers ("st-hva/regs")
- the information about the last closed instance ("st-hva/last")
Moreover, a debugfs entry is dynamically created for each opened instance,
("st-hva/<instance identifier>") to dump:
- the information about the stream (profile, level, resolution,
alignment...)
- the control parameters (bitrate mode, framerate, GOP size...)
- the potential (system, encoding...) errors
- the performance information about the encoding (HW processing
duration, average bitrate, average framerate...)
Each time a running instance is closed, its context (including the debug
information) is saved to feed, on demand, the last closed instance debugfs
entry.
These debug capabilities are mainly implemented in the hva-debug.c file.
