Subject: [PATCH 0/4] PCI: dwc: Do not enumerate bus before endpoint devices are ready
Date: Wed, 11 Jun 2025 12:51:41 +0200 [thread overview]
Message-ID: <20250611105140.1639031-6-cassel@kernel.org> (raw)
Hello all,
The DWC PCIe controller driver currently does not follow the PCIe
specification with regards to the delays after link training, before
sending out configuration requests. This series fixes this.
At the same time, PATCH 1/4 addresses a regression where a Plextor
NVMe drive fails to be configured correctly. With this series, the
Plextor NVMe drive works once again.
Kind regards,
Niklas

up
PCI: dwc: Reduce LINK_WAIT_SLEEP_MS
