Subject: [PATCH 11/18] Delayed mips setup of PCI IRQs to bus scan time
Date: Thu, 2 Oct 2014 04:50:30 +0100 [thread overview]
Message-ID: <1412221837-17452-12-git-send-email-matt@masarand.com> (raw)
In-Reply-To: <1412221837-17452-1-git-send-email-matt@masarand.com>
From: Matthew Minter <matt@masarand.com>
Currently mips PCI IRQs are assigned at boot, this creates an extra
pass over the PCI bus and causes hot-plugged devices which are not
present at boot to not be given IRQs, this patch set fixes this by
registering assignment functions which are then run later during the
device enable code path.
