I finally got around trying this both on Jetson TK1 as well as our own Toradex Apalis TK1 module we are about to mainline. I actually applied your patch set on top of 4.6.0-rc1. While USB 3.0 seems to work fine I noticed PCIe and SATA no more to come up right with the following message: [ 2.794458] tegra-pcie 1003000.pcie-controller: PLL failed to lock: -110 [ 2.801177] tegra-pcie 1003000.pcie-controller: failed to power on PHY: -110 [ 2.809031] tegra-pcie: probe of 1003000.pcie-controller failed with error -110 Do you happen to know what could be the issue? As for USB I do get some message about the endpoint companion but do not know whether or not this is to be expected: [ 1021.575301] usb 4-1: new SuperSpeed USB device number 2 using tegra- xusb [ 1021.598913] usb 4-1: No SuperSpeed endpoint companion for config 1 interface 0 altsetting 0 ep 2: using minimum values Otherwise it looks good: ubuntu@tegra-ubuntu:~$ lsusb Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 002: ID 0951:1666 Kingston Technology DataTraveler G4 Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub And performs satisfactorily (up from around 24 MB/sec with just USB 2.0): ubuntu@tegra-ubuntu:~$ sudo hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 94 MB in 3.05 seconds = 30.81 MB/sec Apalis TK1 actually features two USB 3.0 host ports: ubuntu@tegra-ubuntu:~$ lsusb Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 005 Device 002: ID 0951:1666 Kingston Technology DataTraveler G4 Bus 005 Device 003: ID 1f75:0902 Innostor Technology Corporation IS902 UFD controller Bus 005 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub ubuntu@tegra-ubuntu:~$ sudo hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 96 MB in 3.00 seconds = 31.98 MB/sec ubuntu@tegra-ubuntu:~$ sudo hdparm -t /dev/sdb /dev/sdb: Timing buffered disk reads: 152 MB in 3.04 seconds = 49.99 MB/sec Cheers Marcel > Signed-off-by: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public. > gmane.org> > --- > Changes in v10: > - clarify that the hardware documentation means something different > when > referring to a "port" (intra-SoC connectivity) > > Changes in v9: > - rename UTMI -> USB2 to match hardware documentation > - reword according to suggestions by Stephen Warren > - make Tegra132 compatible string list consistent > - remove mailbox support > ... -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
