Subject: [PATCH 1/2] tuna: Print warning if setting affinity results in EBUSY
|
||||
and continue
|
||||
|
||||
When trying to isolate a CPU, if a device uses SCHED_DEADLINE and admission
|
||||
control is enabled, setting the affinity will result in the error EBUSY.
|
||||
|
||||
tuna should print a warning that this pid could not be moved, and
|
||||
continue.
|
||||
|
||||
The user can either ignore the warning or use other measures to isolate
|
||||
the cpu such as booting with isolcpus or turning off admission control
|
||||
and rerunning the tuna isolate command and then turning admission
|
||||
control back on.
