In some industries, that’s exactly what Linux does, thanks to advances like kpatch and kgraph.įor laptop and desktop users, though, that metric is a little extreme. Linux is fully capable of running not weeks, but years, without a reboot. May 05 14:44:18. systemd: Started Load CPU microcode update. May 05 14:44:18. systemd: Starting Load CPU microcode update.

USR CPUINFO HOW TO
Note that I'm not worrying here how to further quote and escape this to be able to wrap it in 'bash -c' and place that in an ExecStart= line - all the more reason to put whatever one decides to use inside an auxiliary script file! || echo 1 > /sys/devices/system/cpu/microcode/reload Grep -q '^vendor_id]*: GenuineIntel$' /proc/cpuinfo \ If you're going to try to use a one-(long-)line shell construct (and including robustifying the grep patterns, which Frank started, but didn't carry far enough) how about something much more straightforward like this: But even more so, what is that horrible shell construct? Grep for 'GenuineIntel' in /proc/cpuinfo and return the name of the file if it matches, then xargs that into grepping for 'model 79' in whatever file might have had a match from the first grep (gee, might it have been /proc/cpuinfo?), tossing away any matches found into /dev/null and then if that found nothing, then do the echo. I have to agree w/ Harald that this is one of the ungodliest kludges I have ever seen.įirst, yes, it should have been put in an auxiliary script rather than being shoehorned in with 'bash -c'. +ExecStart=/usr/bin/bash -c 'grep -l GenuineIntel /proc/cpuinfo | xargs grep -l "model.*79" > /dev/null || echo 1 > /sys/devices/system/cpu/microcode/reload' ExecStart=/usr/bin/bash -c "grep -l GenuineIntel /proc/cpuinfo | xargs grep -l "model.*79" > /dev/null || echo 1 > /sys/devices/system/cpu/microcode/reload" The simplest fix could be to replace the outer quotes with single apostrophes: Loaded: loaded (/usr/lib/systemd/system/rvice enabled vendor preset: enabled) Led 09 09:23:19 localhost systemd: rvice lacks both ExecStart= and ExecStop= setting. Led 09 09:23:19 localhost systemd: Trailing garbage, ignoring.
Version-Release number of selected component (if applicable): In the journal I can see systemd reports errors about loading the unit. The latest update of microcode_ctl broke the rvice systemd unit.
