Hi Hans,
Thank you for your remarks about the 2 debug patches for HVA.
I've just sent a version 2 with the following propositions:
- the encoding summary (first patch) doesn't include any longer information
about the encoding performance. There's no more computation in this patch
(hva_dbg_perf_begin and hva_dbg_perf_end removed). Thus, there's no potential
penalty on the encoding performance. So, I propose that the short summary (very
useful to easily get a status about the encoding operation) is always enabled
(dev_info).
- for the second patch, I propose that the computation of the performances
(hva_dbg_perf_begin and hva_dbg_perf_end) is conditioned by CONFIG_DEBUG_FS. It
avoids the definition of a new Kconfig option (mkt-vpu also uses
CONFIG_DEBUG_FS). As to the functions that manage the debugfs entries
(hva_*_create/remove), I propose that they are called even if DEBUG_FS is
disabled: in this case, thanks to the debugfs API, the entries will simply not
created.
Finally, I think that your proposition of having a Kconfig in the sti directory
makes sense. It might be part of a different patch series dealing with the "sti
coherency" (we discussed about that on IRC with Benjamin Gaignard few weeks
ago).
Regards,
Jean-Christophe.
