Subject: [PATCH v4 pci 0/2] PCI/MSI: pci-xgene-msi: Enable MSI support in ACPI boot for X-Gene v1
Date: Tue, 26 Sep 2017 11:49:19 -0600 [thread overview]
Message-ID: <1506448161-30961-1-git-send-email-kdinh@apm.com> (raw)
This patch set enables ACPI MSI support for X-Gene PCIe v1 hardware
and provides the proper MSI driver initialization ordering.
Signed-off-by: Khuong Dinh <kdinh@apm.com>
---
v4:
- Remove Marc Zyngier ACK in v2
- Use acpi_bus_scan on MSI controller handle when MSI device is found
- Register ACPI MSI driver when MSI device is found instead of using
subsys_initcall
- Split ACPI MSI driver support into two patches - one to enable MSI
support for X-Gene PCIe v1 hardware, one to enforce MSI driver loaded
before PCIe controller driver in ACPI boot mode
v3:
- Input X-Gene MSI base address for irq_domain_alloc_fwnode
- Add a hook to enforce X-Gene MSI be probed prior acpi_bus_scan happens
v2:
- Verify with BIOS version 3.06.25 and 3.07.09
v1:
- Initial version
