[PATCH v4 0/4] media: venus: Update clock scaling and core selection
From: Aniket Masule
Date: Tue Jul 02 2019 - 10:46:57 EST
In this patch series, clock scaling and core selection methods are
updated. Current clock scaling and core selection methods are same
for vpu4 and previous versions. Introducing load calculations using
vpp cycles, which indicates the cycles required by video hardware to
process each macroblock. Also adding vsp cycles, cycles require by
stream processor. Clock scaling is now done more precisely using vpp
and vsp cycles. Instance is assigned to core with minimum load, instead
of static assignment.
Changes since v3:
- vsp_cycles and vpp_cyles are now unsigned long.
- Core number counting aligned with VIDC_CORE_ID_.
- Aligned hardware overload handling of scale_clocks_v4 with scale_clocks.
- Added bitrate based clock scaling patch in this patch series.
- Instance state check is now moved from scale_clocks to load_scale_clocks.
