| * [SCSI] uas: disable use of blk-mq I/O pathChristoph Hellwig2014-10-031-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | The uas driver uses the block layer tag for USB3 stream IDs. With blk-mq we can get larger tag numbers that the queue depth, which breaks this assumption. A fix is under way for 3.18, but sits on top of large changes so can't easily be backported. Set the disable_blk_mq path so that a uas device can't easily crash the system when using blk-mq for SCSI.

* | USB: storage: Add quirks for Entrega/Xircom USB to SCSI convertersMark2014-09-201-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB- SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI chain to be accessed. Without it only the (single) device with SCSI ID 0 can be used. The standalone converter sold by Entrega had model number U1-SC25. Xircom acquired Entrega and re-branded the product line PortGear. The PortGear USB to SCSI Converter (model PGSCSI) is internally identical to the Entrega product, but later models may use a different USB ID. The Entrega-branded units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and Macintosh drivers also support 085A:0028. Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac (8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may have initially used the same ID as the standalone U1-SC25 (1645:0007), but later production used 085A:0026. My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133 probably also exist. This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I couldn't find any mention of that actually existing in the wild; perhaps it was cancelled before release?

* | USB: storage: Add quirk for Ariston Technologies iConnect USB to SCSI adapterMark2014-09-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi, The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g. iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM Microsystems chips. Only the connectors differ; both have the same USB ID. The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other than 0. I don't have one of these, but based on the other entries for Shuttle/ SCM-based converters this patch is very likely correct. I used 0x0000 and 0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which bcdDevice value the products use.

* | USB: EHCI: unlink QHs even after the controller has stoppedAlan Stern2014-09-191-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Old code in ehci-hcd tries to expedite disabling endpoints after the controller has stopped, by destroying the endpoint's associated QH without first unlinking the QH. This was necessary back when the driver wasn't so careful about keeping track of the controller's state. But now we are careful about it, and the driver knows that when the controller isn't running, no unlinking delay is needed. Furthermore, skipping the unlink step will trigger a BUG() in qh_destroy() when the preceding QH is released, because the link pointer will be non-NULL. Removing the lines that skip the unlinking step and go directly to QH_STATE_IDLE fixes the problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Resuming from hibernate (S4) will restart and re-initialize xHC. The device contexts are freed and will be re-allocated later during device reset. Usb core will disable link pm in device resume before device reset, which will try to change the max exit latency, accessing the device contexts before they are re-allocated. There is no need to zero (disable) the max exit latency when disabling hw lpm for a freshly re-initialized xHC. So check that device context exists before doing anything. The max exit latency will be set again after device reset when usb core enables the link pm.

This is a result of two things: 1. xhci_mem_cleanup() in xhci-mem.c free's xhci->lpm_command if it's not NULL, but doesn't set it to NULL after the free. 2. xhci_mem_cleanup() is called twice on resume, once for normal restart and once from xhci_mem_init() if dma_alloc_coherent() fails, resulting in a free of xhci->lpm_command that has already been freed. The fix is to set xhci->lpm_command to NULL after freeing it.

Where as in BOT mode they appear to work fine, so the best way forward with these devices is to just blacklist them for uas usage. Unfortunately this is easier said then done. as older versions of the ASM1053 (which works fine) use the same usb-id as the ASM1051. When connected over USB-3 the 2 can be told apart by the number of streams they support. So this patch adds some less then pretty code to disable uas for the ASM1051. When connected over USB-2, simply disable uas alltogether for devices with the shared usb-id.

That condition would trigger a fake connection to a non-existent device so that usbcore would trigger a warm reset of the port, thus taking the link out of reset. This has the side-effect of preventing any xHCI host connected to a Linux machine from starting and running the USB 3.0 Electrical Compliance Suite because the port will mysteriously taken out of compliance mode and, thus, xHCI won't step through the necessary compliance patterns for link validation. This patch fixes the issue by just adding a missing check for XHCI_COMP_MODE_QUIRK inside xhci_hub_report_usb3_link_state() when PORT_CAS isn't set.

The known example uses interface numbers 12 and 13 for the ECM control and data interfaces respectively, consistent with CDC MBIM function interface numbering on other Sierra devices. It seems cleaner to restrict this driver to the ff/ff/ff vendor specific interfaces rather than increasing the already long interface number blacklist. This should be more future proof if Sierra adds more class functions using interface numbers not yet in the blacklist.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PHY configuration is stored in an opaque "config" field, but when allocating the structure, its proper size needs to be known. In the case of UTMI, the proper structure is tegra_utmip_config of which a local variable already exists, so we can use that to obtain the size from.

It was result of fact that maximum endpoint address was taken as total number of endpoints in function. This patch adds endpoint descriptors counting and storing their addresses in eps_addrmap to verify their cohesion in each speed. Endpoint address map would be also useful for further features, just like vitual endpoint address mapping.

This function will be called after a transmission finished by DMAC. So, the function should check if the transmission packet is short packet or not. Also the function should call try_run to send the zero packet by the pio handler if the "*is_done" is not set. Otherwize, the transaction will not finish if a gadget driver sets the "zero" flag in a transmission.
