AMD Support Being Added To UFS Host Controller PCI Driver In Linux 7.2

Source Domain: www.phoronix.com

Linux’s ufshcd-pci as the Universal Flash Storage host controller PCI driver has supported a variety of Intel devices to this point while for Linux 7.2 the first AMD device is set to be added.

A patch was posted to the Linux kernel mailing list last week by an AMD engineer to add a PCI device for AMD UFS controllers. This AMD 0x1B29 ID for UFS controllers is the first non-Intel product being added to this ufshcd-pci driver. No other changes are needed to this ufshcd-pci common driver besides adding the AMD vendor/device ID addition.

The patch doesn’t elaborate on what product(s) this is ultimately going to correlate to for this UFS host controller driver. Within the Linux kernel there is already the ufs-amd-versal2 UFS host controller driver for Versal2 SoCs. So presumably this new addition to the ufshcd-pci is for non-Versal AMD wares.

In any event, the patch is now applied and confirmed for its planned submission to the upcoming Linux 7.2 kernel cycle.
