[PATCH 5.15 042/117] xhci-pci: set the dma max_seg_size

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ricardo Ribalda <ribalda@xxxxxxxxxxxx>

commit 93915a4170e9defd56a767a18e6c4076f3d18609 upstream.

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]
