Hello,
The goal of those two patches is to add debug and trace capabilities to CMA on going development.
The first patch allow to dump CMA bitmap status by a simple "cat /sys/kernel/debug/cma" command line.
The second add events trace points that can be used for performance and/or log with trace tools: - to enable it "echo 1 > /sys/kernel/debug/tracing/events/cma/enable" - to get the log "cat /sys/kernel/debug/tracing/events/trace"
Regards,
Benjamin
Hi all,
I have rebase my patches for debugfs and trace events on top of CMA v17.
