From: Jacob Keller Date: Thu, 19 Jan 2023 01:16:52 +0000 (-0800) Subject: ice: introduce .irq_close VF operation X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=537dfe06accad68123fe780ce4f883549a73db37;p=linux.git ice: introduce .irq_close VF operation The Scalable IOV implementation will require notifying the VDCM driver when an IRQ must be closed. This allows the VDCM to handle releasing stale IRQ context values and properly reconfigure. To handle this, introduce a new optional .irq_close callback to the VF operations structure. This will be implemented by Scalable IOV to handle the shutdown of the IRQ context. Since the SR-IOV implementation does not need this, we must check that its non-NULL before calling it.
