Subject: [RFC PATCH 0/3] hw/arm/virt: CXL enablement including gpex-acpi
Date: Mon, 1 Feb 2021 23:26:52 +0800	[thread overview]
Message-ID: <20210201152655.31027-1-Jonathan.Cameron@huawei.com> (raw)

Very basic initial enablement of CXL on arm virt with relevant ACPI table
construction. Includes changes in gpex-acpi to ensure correct DSDT for
any pci_expand_bridge/pxb-cxl bridges.  Note not looking to do the
primary root bridge yet.

Based on Ben's tree cxl-2.0v3 at https://gitlab.com/bwidawsk/qemu

To actually get the memory appropriately exposed to the OS a few additional
changes are needed as discussed in thread
https://lore.kernel.org/qemu-devel/20210128174009.00007536@Huawei.com/

I will rebase this on future versions of Ben's series as needed.
