Subject: [PATCH v3 20/27] powerpc/powernv/pmem: Forward events to userspace
Date: Fri, 21 Feb 2020 14:27:13 +1100 [thread overview]
Message-ID: <20200221032720.33893-21-alastair@au1.ibm.com> (raw)
In-Reply-To: <20200221032720.33893-1-alastair@au1.ibm.com>
From: Alastair D'Silva <alastair@d-silva.org>
Some of the interrupts that the card generates are better handled
by the userspace daemon, in particular:
Controller Hardware/Firmware Fatal
Controller Dump Available
Error Log available
This patch allows a userspace application to register an eventfd with
the driver via SCM_IOCTL_EVENTFD to receive notifications of these
interrupts.
Userspace can then identify what events have occurred by calling
SCM_IOCTL_EVENT_CHECK and checking against the SCM_IOCTL_EVENT_FOO
masks.
