Public bug reported: Three patches are needed to add support for Amazon / Annapurna Labs "Graviton" PCIe controller, which is required for future AWS instance types.
The feature is to be enabled for Ubuntu kernels >= linux-aws-bionic. The first patch is from mainline; the other two are AWS specific quirks from Amazon Linux, not yet upstream. 4166bfe530 PCI: al: Add Amazon Annapurna Labs PCIe host controller driver UBUNTU: SAUCE: [aws] irqchip/gic-v2m: invoke from gic-v3 initialization and add acpi quirk flow UBUNTU: SAUCE: [aws] arm64: acpi/pci: invoke _DSM whether to preserve firmware PCI setup ** Affects: linux-aws (Ubuntu) Importance: Undecided Assignee: Kamal Mostafa (kamalmostafa) Status: In Progress ** Affects: linux-aws (Ubuntu Bionic) Importance: Undecided Assignee: Kamal Mostafa (kamalmostafa) Status: In Progress ** Affects: linux-aws (Ubuntu Cosmic) Importance: Undecided Status: New ** Affects: linux-aws (Ubuntu Disco) Importance: Undecided Status: New ** Affects: linux-aws (Ubuntu Eoan) Importance: Undecided Assignee: Kamal Mostafa (kamalmostafa) Status: In Progress ** Affects: linux-aws (Ubuntu Ff-series) Importance: Undecided Status: New ** Description changed: Three patches are needed to add support for Amazon / Annapurna Labs "Graviton" PCIe controller, which is required for future AWS instance types.
