Subject: [PATCH v3 0/4] Add binder state and statistics to binderfs
Date: Tue, 3 Sep 2019 09:16:51 -0700 [thread overview]
Message-ID: <20190903161655.107408-1-hridya@google.com> (raw)
Currently, the only way to access binder state and
statistics is through debugfs. We need a way to
access the same even when debugfs is not mounted.
These patches add a mount option to make this
information available in binderfs without affecting
its presence in debugfs. The following debugfs nodes
will be made available in a binderfs instance when
mounted with the mount option 'stats=global' or 'stats=local'.
/sys/kernel/debug/binder/failed_transaction_log
/sys/kernel/debug/binder/proc
/sys/kernel/debug/binder/state
/sys/kernel/debug/binder/stats
/sys/kernel/debug/binder/transaction_log
/sys/kernel/debug/binder/transactions
Hridya Valsaraju (4):
binder: add a mount option to show global stats
binder: Add stats, state and transactions files
binder: Make transaction_log available in binderfs
binder: Add binder_proc logging to binderfs
