Bart Van Assche [Sat, 12 Sep 2020 14:58:00 +0000 (07:58 -0700)]
helper_thread: Increase timer accuracy

The helper_thread uses select() to wait for the next event. select() rounds
up its timeout argument to 1 / HZ. Increase timer accuracy by using a
high-res timer if possible. This patch has been tested by running the
following fio command and by verifying that the next_log and
msec_to_next_event were always above 100 ms:

./fio --debug=helperthread --bandwidth-log --write_bw_log=log --log_avg_msec=1000 --ioengine=null --name=null --size=1G --rw=randwrite --loops=999999 --runtime=60

To avoid this inconsistency, initialize the open zone list referring the

Shin'ichiro Kawasaki [Tue, 1 Sep 2020 08:20:00 +0000 (17:20 +0900)]
zbd: Decrement open zones count at write command completion

When max_open_zones or job_max_open_zones option is provided, fio counts
number of open zones. This open zone accounting is done during submission
of write commands. When write command is submitted to a zone for the
first time, the zone is counted as open. When a write command which will
fill the zone gets submitted, the zone is counted as closed. However,
this count at write command submission may open zones more than the
limit. When writes to zones more than the limit are submitted with high
queue depth, those writes in-flight open zones more than the limit.

To avoid such writes beyond max open zones limit, decrement number of
open zones count not at write command submission but at write command
completion. By doing this, the number of zones with in-flight write
commands are kept within the limit with accuracy. Introduce the helper
function zbd_end_zone_io() for this decrement and zbd_close_zone() call.

The zbd_close_zone() function requires thread_data argument. To refer
thread_data at write command completion, add the argument to zbd_put_io()
and zbd_queue_io() callbacks. Also add a loop to the zbd_close_zone()
function which converts zone_info array index to open_zones array index
to avoid loop code duplication.

Even when io_u points to an open zone, the zone may not be valid for
write since in-flight write commands may make the zone full. Check this
in zbd_open_zone() to handle such zones as in full status.

Because of the zone close timing change, there might be no open zone when
zbd_convert_to_open_zone() is called. Do not handle such case as an
error and open other zones.

When zbd_convert_to_open_zone() finds all open zones can not be used for
next write, it opens other zones. This zone open fails when the number of
open zones hits one of the limits: 1) number of zones in the fio write
target region, 2) max_open_zones option or 3) job_max_open_zones option.
To avoid the zone open failure, wait for writes in-flight completes and
open zones get closed before opening other zones.

flow: add ability for weight-based flow control on multiple jobs

Fixes: #741 - fio how to run mix workload all 4 patterns in one job file

Previously, 'flow' was used to regulate activity between 2 or more jobs with
certain weight.  However, the implementation was ineffective when regulating
more than 2 jobs with different weights, since it relied on a single,
shared counter, and was missing logic to track individual job's activity
and regulate it according to it's requested weight in proportion to other jobs'
requested weight and activity.

This commit modifies the 'flow' functionality to track each job's
activity and the total activity belonging to a 'flow_id' group.
Using this new information, the 'flow' logic is then modified to
regulate a job's activity in proportion to other jobs in the
same group.  Similar to previous behavior, the regulation is done by
stalling a job's activity.

New jobs joining an existing 'flow_id' group or jobs repead from said
group will cause re-calibration of the weights and alter the activity as a
result.  For example, 3 jobs (j1,j2,j3) with weights (1:2:3)
respectively will maintain activity ratio of 1:2:3.  Thus, j1 will have
activity of 1/6, j2 - 2/6 and j3 - 1/2.

If j3 exits prematurely, the proportion is re-calibrated
such that j1 will strive to have activity of 1/3 and j2 - 2/3.

Re-calibration phase may cause a hiccup in the activity of one or more
jobs since the new desired proportion might not be achieved quickly
enough.
