[PATCH v2 3/3] usb/hcd-xhci: Split pci wrapper for xhci base model |
|
Date: |
Wed, 24 Jun 2020 19:46:16 +0530 |
This patch sets the base to use xhci as sysbus model, for which pci
specific hooks are moved to hcd-xhci-pci.c. As a part of this requirment
msi/msix interrupts handling is moved under XHCIPCIState, and XHCIState
is non qom object, make use of 'container_of' calls to retrive
XHCIPciState. Made required changes for qemu-xhci-nec.
