Subject: [Qemu-devel] [PATCH v3 0/2] PCI-e device multi-function hot-add support
Date: Tue, 13 Oct 2015 16:41:33 +0800	[thread overview]
Message-ID: <1444725695-27517-1-git-send-email-caoj.fnst@cn.fujitsu.com> (raw)

Support PCI-e device hot-add multi-function via device_add, just ensure
add the function 0 is added last. While allow user to roll back in the
middle via device_del, in case user regret.

changelog:
1. Flag device as unexposed when func 0 doesn`t exist, via return 0xFF
   in case of gratuitous pci bus scan.
2. Since device is unexposed to guest, can remove function individually,
   without interaction with the guest.

Cao jin (2):
  enable multi-function hot-add
  remove function during multi-function hot-add
