Whilst I know others are working on an implementation of at least some of
this, a desire to work on the kernel user of this required an
implementation so I threw this together in the meantime and am sending
it out on the basis that it may be of use to others.
As it is an RFC I have been lazy on some cleanup and error handling.
Will fix that in a future version if we decide to take this forwards.
Based on Ben's cxl-2.0v3 branch from https://gitlab.com/bwidawsk/qemu
Possible I've picked an unstable branch so this may or may not currently
apply :) I'll rebase on Ben's next version when avaialble.
Jonathan Cameron (4):
include/standard-headers/linux/pci_regs: temp hack to add necessary
DOE definitions.
hw/pci/pcie_doe: Introduce utility functions for PCIe DOE
hw/cxl/cxl-cdat: Initial CDAT implementation for use by CXL devices
hw/mem/cxl_type3: Enabled DOE mailbox for access to CDAT
