From: Alex Williamson <alex.williamson@redhat.com> To: linux-pci@vger.kernel.org Cc: linux-kernel@vger.kernel.org, linux-nvme@lists.infradead.org Subject: [PATCH 0/2] PCI: NVMe reset quirk Date: Mon, 23 Jul 2018 16:24:14 -0600 [thread overview] Message-ID: <20180723221533.4371.90064.stgit@gimli.home> (raw) As discussed in the 2nd patch, at least one NVMe controller sometimes doesn't like being reset while enabled and another will timeout during a subsequent re-enable if it happens too quickly after reset. Introduce a device specific reset quirk for all NVMe class devices so that we can try to get reliable behavior from them for device assignment and any other users of the PCI subsystem reset interface. Patches against current PCI next branch.
