[PATCH v2 0/5] media: venus: Update clock scaling and core selection
From: Aniket Masule
Date: Tue Jun 11 2019 - 02:10:14 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. Clock scaling is now done more precisely using
vpp cycles. Instance is assigned to core with minimum load, instead of
of static assignment
Changes since v1:
- Corrected VPP cycles entries in codec data table.
- Removed filled_len from arguments to calculate_inst_freq,
filled_len won't be used in this patch series.
filled_len will be used in clock scaling based on bitrate.
