What:		/sys/block/<disk>/bcache/unregister

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		A write to this file causes the backing device or cache to be

		unregistered. If a backing device had dirty data in the cache,

		writeback mode is automatically disabled and all dirty data is

		flushed before the device is unregistered. Caches unregister

		all associated backing devices before unregistering themselves.



What:		/sys/block/<disk>/bcache/clear_stats

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		Writing to this file resets all the statistics for the device.



What:		/sys/block/<disk>/bcache/cache

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For a backing device that has cache, a symlink to

		the bcache/ dir of that cache.



What:		/sys/block/<disk>/bcache/cache_hits

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For backing devices: integer number of full cache hits,

		counted per bio. A partial cache hit counts as a miss.



What:		/sys/block/<disk>/bcache/cache_misses

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For backing devices: integer number of cache misses.



What:		/sys/block/<disk>/bcache/cache_hit_ratio

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For backing devices: cache hits as a percentage.



What:		/sys/block/<disk>/bcache/sequential_cutoff

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For backing devices: Threshold past which sequential IO will

		skip the cache. Read and written as bytes in human readable

		units (i.e. echo 10M > sequntial_cutoff).



What:		/sys/block/<disk>/bcache/bypassed

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		Sum of all reads and writes that have bypassed the cache (due

		to the sequential cutoff).  Expressed as bytes in human

		readable units.



What:		/sys/block/<disk>/bcache/writeback

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For backing devices: When on, writeback caching is enabled and

		writes will be buffered in the cache. When off, caching is in

		writethrough mode; reads and writes will be added to the

		cache but no write buffering will take place.



What:		/sys/block/<disk>/bcache/writeback_running

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For backing devices: when off, dirty data will not be written

		from the cache to the backing device. The cache will still be

		used to buffer writes until it is mostly full, at which point

		writes transparently revert to writethrough mode. Intended only

		for benchmarking/testing.



What:		/sys/block/<disk>/bcache/writeback_delay

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For backing devices: In writeback mode, when dirty data is

		written to the cache and the cache held no dirty data for that

		backing device, writeback from cache to backing device starts

		after this delay, expressed as an integer number of seconds.



What:		/sys/block/<disk>/bcache/writeback_percent

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For backing devices: If nonzero, writeback from cache to

		backing device only takes place when more than this percentage

		of the cache is used, allowing more write coalescing to take

		place and reducing total number of writes sent to the backing

		device. Integer between 0 and 40.



What:		/sys/block/<disk>/bcache/synchronous

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For a cache, a boolean that allows synchronous mode to be

		switched on and off. In synchronous mode all writes are ordered

		such that the cache can reliably recover from unclean shutdown;

		if disabled bcache will not generally wait for writes to

		complete but if the cache is not shut down cleanly all data

		will be discarded from the cache. Should not be turned off with

		writeback caching enabled.



What:		/sys/block/<disk>/bcache/discard

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For a cache, a boolean allowing discard/TRIM to be turned off

		or back on if the device supports it.



What:		/sys/block/<disk>/bcache/bucket_size

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For a cache, bucket size in human readable units, as set at

		cache creation time; should match the erase block size of the

		SSD for optimal performance.



What:		/sys/block/<disk>/bcache/nbuckets

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For a cache, the number of usable buckets.



What:		/sys/block/<disk>/bcache/tree_depth

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For a cache, height of the btree excluding leaf nodes (i.e. a

		one node tree will have a depth of 0).



What:		/sys/block/<disk>/bcache/btree_cache_size

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		Number of btree buckets/nodes that are currently cached in

		memory; cache dynamically grows and shrinks in response to

		memory pressure from the rest of the system.



What:		/sys/block/<disk>/bcache/written

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For a cache, total amount of data in human readable units

		written to the cache, excluding all metadata.



What:		/sys/block/<disk>/bcache/btree_written

Date:		November 2010

Contact:	Kent Overstreet <kent.overstreet@gmail.com>

Description:

		For a cache, sum of all btree writes in human readable units.
