What:		/proc/diskstats

Date:		February 2008

Contact:	Jerome Marchand <jmarchan@redhat.com>

Description:

		The /proc/diskstats file displays the I/O statistics

		of block devices. Each line contains the following 14

		fields:

		 1 - major number

		 2 - minor mumber

		 3 - device name

		 4 - reads completed succesfully

		 5 - reads merged

		 6 - sectors read

		 7 - time spent reading (ms)

		 8 - writes completed

		 9 - writes merged

		10 - sectors written

		11 - time spent writing (ms)

		12 - I/Os currently in progress

		13 - time spent doing I/Os (ms)

		14 - weighted time spent doing I/Os (ms)

		For more details refer to Documentation/iostats.txt

What:		/sys/block/<disk>/stat

Date:		February 2008

Contact:	Jerome Marchand <jmarchan@redhat.com>

Description:

		The /sys/block/<disk>/stat files displays the I/O

		statistics of disk <disk>. They contain 11 fields:

		 1 - reads completed succesfully

		 2 - reads merged

		 3 - sectors read

		 4 - time spent reading (ms)

		 5 - writes completed

		 6 - writes merged

		 7 - sectors written

What:		/sys/block/<disk>/<part>/stat

Date:		February 2008

Contact:	Jerome Marchand <jmarchan@redhat.com>

Description:

		The /sys/block/<disk>/<part>/stat files display the

		same as the above-written /sys/block/<disk>/stat

		format.

What:		/sys/firmware/acpi/interrupts/

Date:		February 2008

Contact:	Len Brown <lenb@kernel.org>

Description:

		All ACPI interrupts are handled via a single IRQ,

		the System Control Interrupt (SCI), which appears

		as "acpi" in /proc/interrupts.

		However, one of the main functions of ACPI is to make

		the platform understand random hardware without

		special driver support.  So while the SCI handles a few

		well known (fixed feature) interrupts sources, such

		as the power button, it can also handle a variable

		number of a "General Purpose Events" (GPE).

		A GPE vectors to a specified handler in AML, which

		can do a anything the BIOS writer wants from

		OS context.  GPE 0x12, for example, would vector

		to a level or edge handler called _L12 or _E12.

		The handler may do its business and return.

		Or the handler may send send a Notify event

		to a Linux device driver registered on an ACPI device,

		such as a battery, or a processor.

		To figure out where all the SCI's are coming from,

		/sys/firmware/acpi/interrupts contains a file listing

		every possible source, and the count of how many

		times it has triggered.

		$ cd /sys/firmware/acpi/interrupts

		$ grep . *

		gpe_all:241

		sci:241

		sci - The total number of times the ACPI SCI

		has claimed an interrupt.

		gpe_all - count of SCI caused by GPEs.

		gpeXX - count for individual GPE source

		ff_gbl_lock - Global Lock

		ff_pmtimer - PM Timer

		ff_pwr_btn - Power Button

		ff_rt_clk - Real Time Clock

		ff_slp_btn - Sleep Button

		error - an interrupt that can't be accounted for above.

		Root has permission to clear any of these counters.  Eg.

		# echo 0 > gpe11

		All counters can be cleared by clearing the total "sci":

		# echo 0 > sci

		None of these counters has an effect on the function

		of the system, they are simply statistics.

		example would be, if User A has shares = 1024 and user

		B has shares = 2048, User B will get twice the CPU

		bandwidth user A will. For more details refer
