 executing common controller initialization. If the value is available, UFS
 subsystem will ensure the bRefClkFreq attribute of the UFS storage device is
 set accordingly and will modify it if there is a mismatch.

+6. Testing with QEMU
+====================
+
+QEMU emulates a UFS host controller as a PCI device named "ufs" and
+logical units named "ufs-lu". This can be used to test changes to the
+UFS core and to ufshcd-pci without UFS hardware.
+
+The "ufs" and "ufs-lu" devices are available since QEMU 8.2, and the
+"mcq" property since QEMU 9.1.
+
+Enable the following kernel options on top of the architecture
+defconfig::
+
+	CONFIG_SCSI_UFSHCD=y
+	CONFIG_SCSI_UFSHCD_PCI=y
+	CONFIG_BLK_DEV_SD=y
+
+Example for an arm64 guest with one 1 GiB logical unit::
+
+	qemu-img create -f raw ufs.img 1G
+	qemu-system-aarch64 -M virt -cpu max -smp 4 -m 2G -nographic \
+		-kernel arch/arm64/boot/Image -initrd rootfs.cpio.gz \
+		-append "console=ttyAMA0" \
+		-drive file=ufs.img,if=none,id=lu0,format=raw \
+		-device ufs,id=ufs0,serial=0001,mcq=on \
+		-device ufs-lu,drive=lu0,bus=ufs0,lun=0
+
+The logical unit appears as a SCSI disk (for example /dev/sda). Drop
+"mcq=on" to test the single doorbell mode instead of MCQ. The same
+-device options work with qemu-system-x86_64.
+
+The emulation accepts the link startup and hibernate enter/exit UIC
+commands and, since QEMU 11.1, DME get/set and the power mode change
+sequence, but it does not model UniPro, M-PHY or the resulting link
+state. Clock gating hardware and vendor host drivers are not exercised
+either. Changes in those areas still need testing on real hardware.
