Subject: [PATCH 0/2] PCI: hv: Hyper-V vPCI for ARM64
Date: Mon, 13 Sep 2021 17:35:45 +0000 [thread overview]
Message-ID: <MW4PR21MB20022E3A433CFA1558C71485C0D99@MW4PR21MB2002.namprd21.prod.outlook.com> (raw)
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.
This patch series adds support for Hyper-V vPCI for ARM64 by first
breaking the current hard coded dependency in the vPCI code and
making it arch neutral. That is in the first patch. The second
patch introduces a Hyper-V vPCI MSI IRQ chip for allocating SPI
vectors.
This patch depends on two other independent patch sets. First one
is the patch series from Michael Kelley titled:
"Enable Linux guests on Hyper-V on ARM64"
and the second one is from Boqun Feng titled:
"PCI: hv: Support host bridge probing on ARM64". Neither of these
patches are merged into one branch at the moment. I think its best
to carry this patch with the 'hyperv-next' tree after merging Boqun's
patch series.
