Subject: [PATCH 1/7] xhci-pci: set the dma max_seg_size
Date: Mon, 16 Jan 2023 16:22:10 +0200 [thread overview]
Message-ID: <20230116142216.1141605-2-mathias.nyman@linux.intel.com> (raw)
In-Reply-To: <20230116142216.1141605-1-mathias.nyman@linux.intel.com>
From: Ricardo Ribalda <ribalda@chromium.org>
Allow devices to have dma operations beyond 64K, and avoid warnings such
as:
xhci_hcd 0000:00:14.0: mapping sg segment longer than device claims to support [len=98304] [max=65536]
