[PATCH blktests v3 00/12] nvme testsuite runtime optimization

[Daniel Wagner]

Addessed all the comments I got for v2. If I didn't response to all
comments that just means I silently acked them and updated the series
accordingly. Hopefully I didn't miss anything.

I've changed the defaults back to the previous hard coded defaults. That means
the default image size is 1G and the many iterations count is 1000 (nvme/002
always runs 1000 as this is necessary to actually test the page overflow).

This time I also made sure the nvme pci tests nvme/030... get executed. With the
defaults the loop transport gives

loop:
  real    13m17.778s
  user    0m27.396s
  sys     5m48.958s

and with nvme_img_size=16M nvme_num_iter=10 it gets down to

loop:
  real    6m2.588s
  user    0m13.450s
  sys     1m55.236s

Althought some of the tests get skipped (nvme/012, nvme/013) with such small
test image sizes.

The values for tcp and rdma are similiar

tcp:
  real    8m29.010s
  user    0m14.068s
  sys     2m57.573s

rdma:
  real    8m46.285s
  user    0m13.843s
  sys     2m2.662s

get down to

tcp:
  real    2m18.117s
  user    0m5.928s
  sys     0m42.649s

rdma:
  real    2m5.546s
  user    0m6.474s
  sys     0m37.818s

The fc transport is not passing all tests and hence let's ignore it for now.

Obviously you can also turn the values in the other direction and increase the
tests 'coverage'.

Thanks,
Daniel


changes:
v3:
  - 'nvme/rc' instead of 'nvme-rc' subject prefi	x
  - fixed spaces vs tabs indention
  - nvme/014, nvme/015 dropped -1 in #block calculation
  - common/xfs: use 'tail -1' instead 'awk'
  - common/xfs: no need for printf for integer division
  - nvme/035 limit disk size via nvme_img_size
  - set defaults to previous values: nvme_img_size=1G, nvme_num_iter=1000
  - nvme/032, nvme/040 let fio figure out image size
    set timeout to infinity
    cleanup fio
  - add documentation for nvme_tr_type, nvme_img_size and nvme_num_iter
  - limited nproc to 32 for num jobs for random fio job
  - drop job size limit calculation
  - drop nvme_num_iter from nvme/002
  - limit xfs fio job size inside _xfs_run_fio_verify_io()
  - added reviewed tags

v2:
  - made image size configurable via nvme_img_size env
  - make number of iteration configurable via nvme_num_iter
	- do not hard code test values
  - calculate job size
	- use runtime for fio background jobs
  - https://lore.kernel.org/linux-nvme/20230421060505.10132-1-dwagner@xxxxxxx/

v1:
  - initial version
  - https://lore.kernel.org/linux-nvme/20230419085643.25714-1-dwagner@xxxxxxx/
