Subject: [Patch Part2 v5 00/31] Enable hierarchy irqdomian on x86 platforms
Date: Thu, 6 Nov 2014 22:20:13 +0800 [thread overview]
Message-ID: <1415283644-2559-1-git-send-email-jiang.liu@linux.intel.com> (raw)
We plan to restructure x86 interrupt code based on hierarchy irqdomain,
that is to build irqdomains for CPU vector, interrupt remapping unit,
IOAPIC, MSI and HPET etc and organize those irqdomains in hierarchy mode.
Each irqdomain manages corresponding interrupt controller and talks to
parent interrupt controller through public irqdomain interfaces. We also
support stacked irq_chip based on hierarchy irqdomain. It will make the
x86 interrupt architecture much more clear and more easy to maintain
with hierarchy irqdomain and stacked irq_chip. It may also help ARM
interrupt management architecture too.
This is the second patch set to enable support of hierarchy irqdomain
on x86 platforms. It's based on tip/x86/apic branch.
And you may access it at:
https://github.com/jiangliu/linux.git irqdomain/p2v5
And there will be a third patch set to convert IOAPIC driver to support
hierarchy irqdomain and clean up code.
Patch 1-5 enhance irqdomain and irq core to support hierarchy irqdomain
and stacked irqchip.
Patch 6-12 implement an irqdomain to manange CPU interrupt vectors, and
it's the root irqdomain for x86 platforms.
Patch 13-16 converts Intel and AMD interrupt remapping drivers to
support hierarchy irqdomain.
Patch 17-23 converts HPET and MSI to support hierarchy irqdomain.
Patch 24-27 cleans up unsued code in x86 arch and interrupt remapping
drivers.
Patch 28-31 converts DMAR, HTIRQ and UV to support hierarchy irqdomain.
We have tested this patchset on Intel 32-bit and 64-bit systems. And it
also passes Fengguang's 0day tests. But helps are need for testing:
1) AMD HT_IRQ
2) UV platform
V4->V5:
1) Refine PCI MSI interfaces to support hierarchy irqdomain
2) Fix a bug with dealing multiple MSI interrupts
3) Improve commit messages
V3->V4:
1) Simplify IRQ remapping interfaces
2) Hide all IRQ remapping logic from MSI/HPET drivers
3) Move most MSI irqdomain code to public drivers/pci/msi.c so it could
be resued
4) Improve common PCI MSI code
5) Rebase to tip/x86/apic
V2->V3:
1) Fix bugs in handling OF irqdomain
2) Add documentation
3) Rebase to v3.18-rc2
V1->V2
1) Add hierarchy iredomain support of DMAR IRQ and UV IRQ.
2) Fix bugs reported by Joe C.
3) Address all review comments from Thomas
4) Fix a bug found during tests
5) Fix errors and warning found by 0day tests
