Subject: [patch 1/3] genirq: Add config option for reservation mode
Date: Tue, 17 Oct 2017 09:54:57 +0200 [thread overview]
Message-ID: <20171017075600.369375409@linutronix.de> (raw)
In-Reply-To: 20171017075456.694047687@linutronix.de
The interrupt reservation mode requires reactivation of PCI/MSI
interrupts. Create a config option, so the PCI code can set the
corresponding flag when required.
