Subject: [GIT PULL] PCI changes for v3.18
Date: Wed, 8 Oct 2014 11:20:29 -0600 [thread overview]
Message-ID: <20141008172029.GA8854@google.com> (raw)
Hi Linus,
The interesting things here are:
- Turn on Config Request Retry Status Software Visibility. This caused
hangs last time, but we included a fix this time.
- Rework PCI device configuration to use _HPP/_HPX more aggressively
- Allow PCI devices to be put into D3cold during system suspend
- Add arm64 PCI support
- Add APM X-Gene host bridge driver
- Add TI Keystone host bridge driver
- Add Xilinx AXI host bridge driver
Bjorn
