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
