Please follow the link to the first version of the series for a complete description. There are two important changes in this version: a) The previous series was broken because the new parameters were missing from qmp-commands.hx. This is fixed now. [patch 10] b) This series has new tests and documentation [patches 14 and 16] I also added myself as maintainer of the throttling code [patch 17]. Regards, Berto v2: - Patch 10: Add the new parameters to qmp-commands.hx - Patch 14: New iotest for this feature - Patch 15: Fix typo in the API documentation - Patch 16: New document that explains the throttling infrastructure - Patch 17: Add myself as maintainer of the throttling code v1: https://lists.gnu.org/archive/html/qemu-block/2016-02/msg00210.html - Initial version Alberto Garcia (17): throttle: Make throttle_compute_timer() static throttle: Make throttle_conflicting() set errp throttle: Make throttle_max_is_missing_limit() set errp throttle: Make throttle_is_valid() set errp throttle: Set always an average value when setting a maximum value throttle: Merge all functions that check the configuration into one throttle: Use throttle_config_init() to initialize ThrottleConfig throttle: Add support for burst periods throttle: Add command-line settings to define the burst periods qapi: Add burst length parameters to block_set_io_throttle qapi: Add burst length fields to BlockDeviceInfo throttle: Check that burst_level leaks correctly throttle: Test throttle_compute_wait() during bursts qemu-iotests: Extend iotest 093 to test bursts qapi: Correct the name of the iops_rd parameter docs: Document the throttling infrastructure MAINTAINERS: Add myself as maintainer of the throttling code MAINTAINERS | 9 ++ block/qapi.c | 20 ++++ blockdev.c | 99 +++++++++++++----- docs/throttle.txt | 252 +++++++++++++++++++++++++++++++++++++++++++++ hmp.c | 12 +++ include/qemu/throttle.h | 55 +++++++--- qapi/block-core.json | 92 ++++++++++++++--- qmp-commands.hx | 25 +++-- tests/qemu-iotests/093 | 65 +++++++++--- tests/qemu-iotests/093.out | 4 +- tests/test-throttle.c | 88 ++++++++++++---- util/throttle.c | 132 ++++++++++++++++-------- 12 files changed, 708 insertions(+), 145 deletions(-) create mode 100644 docs/throttle.txt -- 2.7.0
