Subject: [PATCH v3 0/2] PCI: hv: Hyper-V vPCI for ARM64
Date: Thu, 14 Oct 2021 08:53:12 -0700 [thread overview]
Message-ID: <1634226794-9540-1-git-send-email-sunilmut@linux.microsoft.com> (raw)
From: Sunil Muthuswamy <sunilmut@microsoft.com>
Current Hyper-V vPCI code only compiles and works for x64. 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
X64 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
