Subject: [PATCH 0/2] irq,xen: fix event channel masking on suspend/resume
Date: Mon, 17 Jul 2017 19:47:01 +0200 [thread overview]
Message-ID: <20170717174703.4603-1-jgross@suse.com> (raw)
Commit bf22ff45bed664aefb5c4e43029057a199b7070c ("genirq: Avoid
unnecessary low level irq function calls") broke Xen suspend/resume
handling as Xen fiddled with masking/unmasking of event channels (or
irqs) without letting the irq subsystem know about it.
Fix this by setting the correct states in irq and remove the masking
from Xen.
Juergen Gross (2):
irq: adjust state of irq in resume_irq() when IRQF_FORCE_RESUME set
xen: dont fiddle with event channel masking in suspend/resume
