Subject: [PATCH v7 0/2] PCI: hv: Hyper-V vPCI for arm64
Date: Fri, 17 Dec 2021 10:51:59 -0800 [thread overview]
Message-ID: <1639767121-22007-1-git-send-email-sunilmut@linux.microsoft.com> (raw)
From: Sunil Muthuswamy <sunilmut@microsoft.com>
Current Hyper-V vPCI code only compiles and works for x86. There are some
hardcoded assumptions about the architectural IRQ chip and other arch
defines.
Add support for Hyper-V vPCI for arm64 by first breaking the current hard
coded dependency using a set of new interfaces and implementing those for
x86 first. That is in the first patch. The second patch adds support for
Hyper-V vPCI for arm64 by implementing the above mentioned interfaces. That
is done by introducing a Hyper-V vPCI specific MSI IRQ domain & chip for
allocating SPI vectors.
changes in v1 -> v2:
- Moved the irqchip implementation to drivers/pci as suggested
by Marc Zyngier
- Addressed Multi-MSI handling issues identified by Marc Zyngier
- Addressed lock/synchronization primitive as suggested by Marc
Zyngier
- Addressed other code feedback from Marc Zyngier
changes in v2 -> v3:
- Addressed comments from Bjorn Helgaas about patch formatting and
verbiage
- Using 'git send-email' to ensure that the patch series is correctly
threaded. Feedback by Bjorn Helgaas
- Fixed Hyper-V vPCI build break for module build, reported by Boqun Feng
changes in v3 -> v4:
- Removed the separate file for IRQ chip that was there in previous
iterations and moved the IRQ chip implementation to pci-hyperv.c.
Feedback by Michael Kelley and Marc Zyngier.
- Addressed various comments from Marc Zyngier about structuring and
layout.
- Addressed comment from Marc Zyngier about IRQ affinity and other
miscellaneous comments.
changes in v4 -> v5:
- Fixed an issue with picking the right cpu for irq affinity, identified
by Marc Zyngier.
changes in v5 -> v6:
- Minor comment updates suggested by Michael Kelley.
changes in v6 -> v7:
- Addressed feedback from Marc Zyngier about IRQ cleanup in the error path
and explicitly setting the IRQ trigger type.
- Address feedback from Bjorn Helgaas about subject line format.
