- Log ----------------------------------------------------------------- commit 5472754c47ed084413da2bc332f2c27a1f5d262a Author: Petri Savolainen petri.savolainen@nokia.com Date: Fri Jan 3 13:36:42 2020 +0200
test: sched_perf: add queue context data touch options
Added -k and -l options to enable performance testing with queue context data touch. Option -k controls the number of (uint64_t) words to read from the queue context (on every received event). Option -l controls the number of words to read and write, after the read only words (-k option).
In forwarding mode next queue handle is stored into the start of the queue context.

Added -n and -m options to enable performance testing with event payload data touch. Option -n controls the number of (uint64_t) words to read from the start of payload data (on each received event). Option -m controls the number of words to read and write, after the read only words (-n option).
