Subject: Re: [Patch V3 00/16] Enable support of IOAPIC hotplug on x86 platforms
Date: Wed, 16 Jul 2014 11:01:45 +0800 [thread overview]
Message-ID: <53C5EB19.7060104@linux.intel.com> (raw)
In-Reply-To: <20140715161035.GA8097@laptop.dumpdata.com>
Hi Konrad,
We have found the root cause with your great support. If BIOS
assigns an IRQ number for a PCI device, acpi_pci_irq_enable() fails to
assign IOAPIC IRQ then due to the check:
if (dev->irq > 0)
return 0;
For a quick workaround, just comment out above check. But we
need some time to figure out a clean fixup for it. We will send out new
version once it gets resolved.
Thanks for your great help again.
Regards!
Gerry
