What: /sys/class/scsi_host/hostX/isci_id
Date: June 2011
Contact: Dave Jiang <dave.jiang@intel.com>
Description:
This file contains the enumerated host ID for the Intel
SCU controller. The Intel(R) C600 Series Chipset SATA/SAS
Storage Control Unit embeds up to two 4-port controllers in
a single PCI device. The controllers are enumerated in order
which usually means the lowest number scsi_host corresponds
with the first controller, but this association is not
guaranteed. The 'isci_id' attribute unambiguously identifies
the controller index: '0' for the first controller,
'1' for the second.

5.2.2 memory.vmscan_stat
memory.vmscan_stat includes statistics information for memory scanning and
freeing, reclaiming. The statistics shows memory scanning information since
memory cgroup creation and can be reset to 0 by writing 0 as
#echo 0 > ../memory.vmscan_stat
This file contains following statistics.
[param]_[file_or_anon]_pages_by_[reason]_[under_heararchy]
[param]_elapsed_ns_by_[reason]_[under_hierarchy]
For example,
scanned_file_pages_by_limit indicates the number of scanned
file pages at vmscan.
Now, 3 parameters are supported
scanned - the number of pages scanned by vmscan
rotated - the number of pages activated at vmscan
freed - the number of pages freed by vmscan
If "rotated" is high against scanned/freed, the memcg seems busy.
Now, 2 reason are supported
limit - the memory cgroup's limit
system - global memory pressure + softlimit
(global memory pressure not under softlimit is not handled now)
When under_hierarchy is added in the tail, the number indicates the
total memcg scan of its children and itself.
elapsed_ns is a elapsed time in nanosecond. This may include sleep time
and not indicates CPU usage. So, please take this as just showing
latency.
Here is an example.

On CPU models which support it, TjMax is read from a model-specific register.
On other models, it is set to an arbitrary value based on weak heuristics.
If these heuristics don't work for you, you can pass the correct TjMax value

help
This option enables the workaround for erratum 764369
affecting Cortex-A9 MPCore with two or more processors (all
current revisions). Under certain timing circumstances, a data
cache line maintenance operation by MVA targeting an Inner
Shareable memory region may fail to proceed up to either the
Point of Coherency or to the Point of Unification of the
system. This workaround adds a DSB instruction before the
relevant cache maintenance functions and sets a specific bit
in the diagnostic control register of the SCU.
