Subject: [PATCH v2 00/26] x86, irq: support ioapic device hotplug
Date: Fri, 8 Feb 2013 11:27:57 -0800 [thread overview]
Message-ID: <1360351703-20571-1-git-send-email-yinghai@kernel.org> (raw)
Hi,
Current x86 code does not support iapic hotplug yet.
This patcheset will try to pre-reserve irq block in allocated_irqs bitmap.
for hot add ioapic controller, also record irq_base in gsi_config, so later
could use it to convert gsi to irq for pci device using that ioapic controller.
Need to new realloc_irq to allocate irq_desc/cfg later.
It is based on x86/apic and pci/next that is supporting pci root bus hotplug now.
could get them from:
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-x86-irq
Yinghai Lu (26):
x86, irq: Change irq_remap_modify_chip_defaults to static
