Description Jiri Kastner 2016-11-11 14:22:19 UTC

Description of problem:
even tuned has realtime and nfv profiles, real low latency can't be achieved without tuning bios, which can be performed manually or in unattended way using bios setting utilities provided by manufacturers. tuned should use those utilities to interact with bios.

Version-Release number of selected component (if applicable):


How reproducible:
always

Steps to Reproduce:
1. yum install @rt
2. rteval -d20m
3. check output

Actual results:
without tuning bios latencies are high despite of applied realtime profile (let say 500us)

Expected results:
with bios options turned to tuned options, administrator will have bigger control of system covering also bios from tuned options.

Comment 2 Jiri Kastner 2016-11-11 15:41:19 UTC

xml format: HP (hp-conrep), dell (syscfg - seems not for all systems), Fujitsu (not managed yet to get it running, needs precompiled modules - no sources)

text config format (option=value): dell

batch script: ibm/lenovo (asu batch file)

calling options on commands line: syscfg --logicproc=disable ...

notes:

syscfg - -i/-ix mostly leads to segfaults, best way is to use --logicproc=disable --cstates=disable --virtualization=disable ...

hp-conrep - probably best way is to use modified conrep.xml (with added options from low latency guide) config for verification and transformation of conrep.dat generated by hp-conrep -s

asu - options differ between (probably) imm versions. x3550 m2/3 have same options, while x3550 m4 has different names, but same like m4/5 from different lines (compared with x3630-m4 and x3650-m5)
