This was tested with dummy_hcd on a local machine. HS, SS + stream support works, command tagging is supported. Ach, it is UAS only right now, BOT is missing. The gadget is configured via configfs like the remaining part of the target framework. This gadget has a _few_ dependencies to get everything working including a few bug fixes in the linux UAS driver for HS or some extensions to the target framework itself. Each patch was posted earlier here or there. My working tree can be found at in the git repository at: git://git.linutronix.de/users/bigeasy/linux.git target_uas it is Linux 3.2 based. Here is my script which which I used for testing: |#!/bin/sh | |#modprobe dummy_hcd is_super_speed=1 |modprobe dummy_hcd |modprobe target_core_mod |modprobe tcm_usb_gadget |mount a -t configfs /sys/kernel/config | |CONFIGFS=/sys/kernel/config/; |TARGET=$CONFIGFS/target/core/ |FABRIC=$CONFIGFS/target/usb_gadget/ | |# RD |mkdir -p $TARGET/rd_mcp_0/ramdisk |echo rd_pages=32768 > $TARGET/rd_mcp_0/ramdisk/control |echo 1 > $TARGET/rd_mcp_0/ramdisk/enable | |# file |mkdir -p $TARGET/fileio_0/fileio |echo "fd_dev_name=/root/file.bin,fd_dev_size=31457280" > $TARGET/fileio_0/fileio/control |echo 1 > $TARGET/fileio_0/fileio/enable | |mkdir -p $FABRIC/naa.6001405c3214b06a/tpgt_1 |mkdir $FABRIC/naa.6001405c3214b06a/tpgt_1/lun/lun_0 |mkdir $FABRIC/naa.6001405c3214b06a/tpgt_1/lun/lun_1 |echo naa.6001405c3214b06b > $FABRIC/naa.6001405c3214b06a/tpgt_1/nexus | |ln -s $TARGET/rd_mcp_0/ramdisk $FABRIC/naa.6001405c3214b06a/tpgt_1/lun/lun_0/virtual_scsi_port |ln -s $TARGET/fileio_0/fileio $FABRIC/naa.6001405c3214b06a/tpgt_1/lun/lun_1/virtual_scsi_port later to connect the gadget: |echo 1 > /sys/kernel/config/target/usb_gadget/naa.6001405c3214b06a/tpgt_1/enable This setups a device with two luns. I believe I addressed all comments which came up on my last RFC. I still have one static tpg because it exposes the gadget framework limitation. Once we extend the gadget framework for multi udc support this limitation can go away.
