*** Liang__ has joined #openstack-nova13:54
sean-k-mooneydo you know who will send it?13:54
gibihuaqiang: thanks13:54
huaqiangwe are not in a same mail loop, I think13:55
huaqiangbasically, SST-BF have a core mask, not every core could be set as high priority13:55
huaqiangbut SST-CP could13:55
*** rpittau_ has joined #openstack-nova13:56
huaqianguser should call the Linux sysfs interface for which core is possible for high priority13:56
sean-k-mooneyhuaqiang: just doing an @intel seach i dont have anything related to this topic in the last day or so.13:56
sean-k-mooneyhuaqiang: yes13:56
sean-k-mooneyso for SST-BF is the core mask fixed in hardware or adjustable13:56
sean-k-mooneyfor sst-cp we can sway which core to priortise for power delivery right using a mask13:57
*** pas-ha has joined #openstack-nova13:57
*** liuyulong has quit IRC13:57
sean-k-mooneyif the cores for SST-BF are fixed in hardware we need to ensure the cpu_dedicated_set and cpu_share_set are alinged to the hardware mask13:58
huaqiangSST-BF core mask is fixed in hardware, and varies from chip to chip, even same CPU type13:58
*** rpittau has quit IRC13:58
huaqiangSST-CP is configuable13:58
sean-k-mooneyok so ya ooo would need to discover that as part of the inspection phase and setup the *_set accordingly for SST-BF13:59
*** Liang__ has quit IRC13:59
huaqiangyes, cpu_dedicated_mask must select from the SST-BF core mask13:59
sean-k-mooneybut for SST-CP we could do it the reverse way around13:59
sean-k-mooneye.g we coudl rpogram the mask based on teh cpu_dedicated_set parmater14:00
huaqiangyes, for SST-CP we can determine a core mask then set it to hardware14:00
sean-k-mooneyill not that in the downstream BZ so that we know about this limitation when we start working on the ooo changes14:01
sean-k-mooney*note14:01
sean-k-mooneyhuaqiang: you would not happen to know how we lookup the hardware mask for SST-BF would you?14:01
sean-k-mooneyis it in /sys? or do we have to check an MSR14:01
huaqianguser need to get the CPU base frequency from ‘/sys/bus/cpu/devices/cpuN/cpufreq/base_frequency’14:03
huaqianghigh priority core will have a higher frequency value14:03
huaqiangso kernel requires >=5.114:04
sean-k-mooneyok so we have to compute it its not just listed14:04
sean-k-mooneywell they woudl only have different based_frequency if the polcy was enabled14:04
sean-k-mooneyby defualt they would all have the same14:04
sean-k-mooneyor are you saying when we turn this on in the bios they go to different base frequencies and we can select the frequency14:05
huaqiangyes14:05
*** Liang__ has joined #openstack-nova14:05
huaqiangthe unit of 'base_frequency' is Mhz, you just read the CPU frequency14:05
huaqiangdo you know, in new platform ,we have another SST14:06
huaqiangthe SST-TF (turbo frequency)14:06
sean-k-mooneythree are 414:06
sean-k-mooneySST-BF adjust base frequency14:06
sean-k-mooneySST-CP adjust the core priport for core power delivery14:07
huaqiangwhich is better for create two groups of CPUs with high or low turbo frequency14:07
huaqiangturbo frequency is commonly used14:07
sean-k-mooneySST-PP disables cores/enables cores to make more power/theremals avilabel for other cores14:07
*** bhagyashris is now known as bhagyashris|afk14:07

*** dave-mccowan has joined #openstack-nova14:23
sean-k-mooneykernel ovs is tricker since some of the processing is also done in the vhost_threads wo ideally you want toes to also be on the high priority cores14:24

sean-k-mooneyhuaqiang: partly yes but i dont belive the core affitiy we apply to the vm cpus applyse to the kernel thread spwaned by the vhost kernel module14:40
sean-k-mooneythe are not forked or spwaned from the process14:40
sean-k-mooneyso i would not assume any cgroup/taskset limits applied to the eumlator thread  or to the vcpus would have any affect on where they run14:41
sean-k-mooneyyou could restict the ovs-vsitchd to a set of thread too but again i thikn that woudl only apply to the user spacee process not the kernel threads. it may be its not clear that it would14:42
sean-k-mooneyanyway i think this is out of scope of nova14:42
huaqiangcan you limit the kernel threads to some CPUs?14:45
huaqiangI know the interrput thread could be pinned14:45
*** mlycka has quit IRC14:46
huaqiangany know nova don't have the capability for kernel pinning14:46

sean-k-mooneygmann: is there a patch to adress the libffi-dev dep for https://review.opendev.org/#/c/738130/116:40
sean-k-mooneyi could add it a bindeps file for os-vif adn list it i guess but this is needed for any pyton lib that uses the forign function interface lib16:41
*** derekh has quit IRC16:41
sean-k-mooneywe dont use it directly its transitive16:41
elodsean-k-mooney: we've just seen the same issue and I think if you change the cffi in lower-constraints.txt to a newer one then that failure won't come16:44
*** xek_ has quit IRC16:45
elodsean-k-mooney: since the problem is that cffi is not there in wheels repo16:45
sean-k-mooneyi doutb it this is becasue we dont have the cpackage so when we compile it fails to find the header16:45
elodat least 1.11.516:45
gmannsean-k-mooney elod it should be from bindep but i have not tried the cffi new version16:45
sean-k-mooneychanging  a pip constratint shoudl not alter that16:45
elodsean-k-mooney: that's why only the lower-constraints job fails and any other passes16:46
sean-k-mooneyhave they started packaging the c header files for cffi?16:46
*** whoami-rajat has quit IRC16:46
sean-k-mooneyhum ok16:46
gmanncffi==1.11.5 is current now.16:47
sean-k-mooneywell we can raise it i guess but really we shoudl just be installing the header file form the distro16:47
*** ociuhandu has joined #openstack-nova16:47
gmannok, let me update the patch and try16:47
elodcffi=1.14.0 is installed without any problem, see https://zuul.opendev.org/t/openstack/build/b8c5b0f682284567949ba9a0b598f61e/log/tox/py38-1.log#6316:48
sean-k-mooneywell we dont have bindeps in os-vif currently are you going to raise the lower-constiat or add a bindep.txt16:48
sean-k-mooneywe shoudl add bindep.txt but there are other things we shoudl do in general fo that.16:48
elodof course, adding bindep.txt with all the relevant binary dependency is a good thing :)16:50
gmannyeah bindeps with libffi-dev [platform:dpkg]16:51
elodjust wanted to let you know why is the weird behavior (failing with lower-constraints job but not at the other jobs)16:51
elod:)16:51
sean-k-mooneydevstafck normally instlls that for us and it used to be installed in the base infra images16:52
sean-k-mooneyso we never needed it until now16:52
sean-k-mooneyeven with older cffi versions16:52
*** gouthamr has joined #openstack-nova16:52
sean-k-mooneythat why we are now seeing it16:52
sean-k-mooneygmann: if you start with adding a bindeps file ill propose followups to add our other deps later16:52
sean-k-mooneye.g. openvswith for our functional tests16:53

gmannsean-k-mooney sure17:13

sean-k-mooneybut i can rebase that on top of yours17:16
gmannsean-k-mooney either is fine or once it pass then we can add in 728037 also.17:18
sean-k-mooneysure both works17:18
sean-k-mooneydo you know what the plannned eta is for the switch to focal17:19
gmannwhich can merge independent of focaltion work17:19
gmannfocal-migration17:19
sean-k-mooneyyep17:19
gmannsean-k-mooney July end for now but i think it might delay.17:19
sean-k-mooneyas i said the dep used to be in the nodepool images and its install by devstack so that is why we are just seing this now17:20
gmannyeah, there are lot of updates in images, so not sure if that is one of that. infra team can confirm17:20
