From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chen Yu Date: Tue, 1 Dec 2020 09:22:09 +0800 Subject: [Intel-wired-lan] [PATCH 2/2][v3] e1000e: Remove the runtime suspend restriction on CNP+ In-Reply-To: References: Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: intel-wired-lan@osuosl.org List-ID: Although there is platform issue of runtime suspend support on CNP, it would be more flexible to let the user decide whether to disable runtime or not because: 1. This can be done in userspace via echo on > /sys/devices/pci0000\:00/0000\:00\:1f.d/power/control 2. More and more NICs would support runtime suspend, disabling the runtime suspend on them by default would impact the validation. Only disable runtime suspend on CNP in case of any user space regression.
