Subject: [RFC][PATCH 0/7] trace memory objects
Date: Mon, 29 Aug 2011 11:29:51 +0800 [thread overview]
Message-ID: <20110829032951.677220552@intel.com> (raw)
Andrew, Ingo,
I'd like to introduce three memory object interfaces
/debug/tracing/objects/mm/pages/dump-pfn
/debug/tracing/objects/mm/pages/dump-file
/debug/tracing/objects/mm/pages/dump-fs
for dumping
- a range of PFNs
- the cached inodes (icache)
- the cached inode pages (page cache)
The "dump-pfn" interface is a superset of the existing /proc/kpageflags and
/proc/kpagecount interfaces. Example output:
# echo 10000 +10 > /debug/tracing/objects/mm/pages/dump-pfn
# cat /debug/tracing/trace
# tracer: nop
#
# TASK-PID CPU# TIMESTAMP FUNCTION

The "dump-file", "dump-fs" interfaces could be pretty useful for examining
the page cache status. Example output:

# echo / > /debug/tracing/objects/mm/pages/dump-fs
# head -50 /debug/tracing/trace
# tracer: nop
