Subject: smartpqi cannot change IRQ smp_affinity
Date: Wed, 30 Jun 2021 22:17:17 +0200 [thread overview]
Message-ID: <c8ed244c-61d0-eead-8ec3-fe8f2e239d71@redhat.com> (raw)
Hi Hellwig and Don,
On driver smartpqi I cannot change smp_affinity and smp_affinity_list
entries.
It was suppose to be fixed by this patch:
https://patchwork.kernel.org/project/linux-scsi/patch/154422179851.1218.10349207247849277036.stgit@brunhilda/
I can see that Hellwig added back PCI_IRQ_AFFINITY flag in commit
5219822687be ("scsi: smartpqi: switch to pci_alloc_irq_vectors").
Is there another way I can control which CPU that process IRQs from the
disk controller?
