* license: Simplify GPL-2.0-or-later license descriptionsPhilippe Mathieu-Daudé2024-09-201-1/+3
| | | | | | | | | | | | Since the "2 | 3+" expression can be simplified as "2+", it is pointless to mention the GPLv3 license. Add the corresponding SPDX identifier to remove all doubt.

* include: Clean up includesPeter Maydell2016-02-231-1/+0
| | | | | | | | | | | | | | 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 BlockDeviceTimedStatsAlberto Garcia2015-11-121-0/+1
| | | | | | | | | | | | | 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.

* util: Infrastructure for computing recent averagesAlberto Garcia2015-11-121-0/+63
This module computes the average of a set of values within a time window, keeping also track of the minimum and maximum values. In order to produce more accurate results it works internally by creating two time windows of the same period, offsetted by half of that period. Values are accounted on both windows and the data is always returned from the oldest one. [Add missing util/replay.o to test-timed-average dependencies to fix the build. --Stefan] Signed-off-by: Alberto Garcia <berto@igalia.com> Message-id: 201b09c21bbc9c329779d2b2365ee2b9c80dceeb.1446044837.git.berto@igalia.com Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
