block: pass OnOffAuto instead of bool to block_acct_setup()

2022-09-30T16:02:30+00:00

We would have one more place for block_acct_setup() calling, which should not corrupt original value. Signed-off-by: Denis V.

block: add empty account cookie type

2019-10-10T08:56:18+00:00

Each block_acct_done/failed call is designed to correspond to a previous block_acct_start call, which initializes the stats cookie. However sometimes it is not the case, e.g. some error paths might report the same cookie twice because it is hard to accurately track if the cookie was reported yet or not. This patch cleans the cookie after report. (Note: block_acct_failed/done without a previous block_acct_start at all should be avoided. Uninitialized cookie might hold a garbage value and there is still "< BLOCK_MAX_IOTYPE" assertion for that) It will be particularly useful in ide code where it's hard to keep track whether the request done its accounting or not: in the following patch of the series, trim requests will do the accounting separately.

block/accounting: introduce latency histogram

2018-03-19T19:58:37+00:00

Introduce latency histogram statics for block devices. For each accounted operation type, the latency region [0, +inf) is divided into subregions by several points. Then, calculate hits for each subregion.

block: make accounting thread-safe

I'm not trying too hard yet. Later, with multiqueue support, this may cause mutex contention or cacheline bouncing.

block: split BlockAcctStats creation and setup

2017-06-15T23:55:00+00:00

block_acct_destroy is called unconditionally in blk_delete, but there is no BlockAcctStats function that is called unconditionally in blk_new. Split block_acct_init in two, so that it will be possible to create a QemuMutex in block_acct_init and destroy it in block_acct_cleanup.

Use scripts/clean-includes to drop redundant qemu/typedefs.h

2016-03-22T21:20:16+00:00

Re-run scripts/clean-includes to apply the previous commit's corrections and updates. Besides redundant qemu/typedefs.h, this only finds a redundant config-host.h include in ui/egl-helpers.c. No idea how that escaped the previous runs. Some manual whitespace trimming around dropped includes squashed in. Signed-off-by: Markus Armbruster Signed-off-by: Paolo Bonzini

include: Clean up includes

2016-02-23T12:43:05+00:00

Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes. NB: If this commit breaks compilation for your out-of-tree patchseries or fork, then you need to make sure you add #include "qemu/osdep.h" to any new .c files that you have.

block: Add average I/O queue depth to BlockDeviceTimedStats

2015-11-12T15:22:46+00:00

This patch adds two new fields to BlockDeviceTimedStats that track the average number of pending read and write requests for a block device. The values are calculated for the period of time defined for that interval.
