2016-04-19usb: wusbcore: remove unreachable codeSudip Mukherjee
The call to wusb_dev_sysfs_rm() which is just after return will never be executed. On checking the code, wusb_dev_sysfs_add() is the last one to be executed so even if that fails we do not need wusb_dev_sysfs_rm() in the error path.

2016-04-19usbip: event handler as one threadNobuo Iwata
Dear all, 1. Overview In current USB/IP implementation, event kernel threads are created for each port. The functions of the threads are closing connection and error handling so they don't have not so many events to handle. There's no need to have thread for each port. BEFORE) vhci side - VHCI_NPORTS(8) threads are created. $ ps aux | grep usbip root 10059 0.0 0.0 0 0 ? S 17:06 0:00 [usbip_eh] root 10060 0.0 0.0 0 0 ? S 17:06 0:00 [usbip_eh] root 10061 0.0 0.0 0 0 ? S 17:06 0:00 [usbip_eh] root 10062 0.0 0.0 0 0 ? S 17:06 0:00 [usbip_eh] root 10063 0.0 0.0 0 0 ? S 17:06 0:00 [usbip_eh] root 10064 0.0 0.0 0 0 ?

S 17:06 0:00 [usbip_eh] BEFORE) stub side - threads will be created every bind operation. $ ps aux | grep usbip root 8368 0.0 0.0 0 0 ? S 17:56 0:00 [usbip_eh] root 8399 0.0 0.0 0 0 ? S 17:56 0:00 [usbip_eh] This patch put event threads of stub and vhci driver as one workqueue. AFTER) only one event threads in each vhci and stub side. $ ps aux | grep usbip root 10457 0.0 0.0 0 0 ? S< 17:47 0:00 [usbip_event] 2. Modification to usbip_event.c BEFORE) kernel threads are created in usbip_start_eh(). AFTER) one workqueue is created in new usbip_init_eh(). Event handler which was main loop of kernel thread is modified to workqueue handler. Events themselves are stored in struct usbip_device - same as before. usbip_devices which have event are listed in event_list. The handler picks an element from the list and wakeup usbip_device. The wakeup method is same as before. usbip_in_eh() substitutes statement which checks whether functions are called from eh_ops or not. In this function, the worker context is used for the checking. The context will be set in a variable in the beginning of first event handling. usbip_in_eh() is used in event handler so it works well. 3. Modifications to programs using usbip_event.c Initialization and termination of workqueue are added to init and exit routine of usbip_core respectively. A. version info v2) # Merged 1/2 event handler itself and 2/2 user programs because of auto build fail at 1/2 casued unmodified user programs in 1/2.

previously we were using a maximum of 32 TRBs per endpoint. With each TRB being 16 bytes long, we were using 512 bytes of memory for each endpoint. However, SLAB/SLUB will always allocate PAGE_SIZE chunks. In order to better utilize the memory we allocate and to allow deeper queues for gadgets which would benefit from it (g_ether comes to mind), let's increase the maximum to 256 TRBs which rounds up to 4096 bytes for each endpoint.

2016-04-14usb: dwc3: gadget: always enable CSPFelipe Balbi
CSP bit of TRB Control is useful for protocols such CDC EEM/ECM/NCM where we're transferring in blocks of MTU-sized requests (usually MTU is 1500 bytes). We know we will always have a short packet after two (for HS) wMaxPacketSize packets and, usually, we will have a long(-ish) queue of requests (for our g_ether gadget, we have at least 10 requests). Instead of always stopping the queue processing to interrupt, giveback and restart, let's tell dwc3 to interrupt but continue processing following request if we have anything already pending in the queue. This gave me a considerable improvement of 40% on my test setup. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

I can't remember the exact size of default FIFO, but it was less than one bulk superspeed packet (<1024) which would prevent USB3 from ever working on OMAP5 ES1.0. However, OMAP5 ES1.0 support has been dropped by commit aa2f4b16f830 ("ARM: OMAP5: id: Remove ES1.0 support") which renders FIFO resizing unnecessary.

Add a flag to indicate that the host is being removed to avoid queueing configure_endpoint commands for the dropped endpoints.

On some xHCI controllers (e.g. R-Car SoCs), the AC64 bit (bit 0) of HCCPARAMS1 is set to 1. However, the xHCs don't support 64-bit address memory pointers actually. So, in this case, this driver should call dma_set_coherent_mask(dev, DMA_BIT_MASK(32)) in xhci_gen_setup(). Otherwise, the xHCI controller will be died after a usb device is connected if it runs on above 4GB physical memory environment.

Nothing major, the normal USB gadget fixes and usb-serial driver ids, along with some other fixes mixed in. All except the USB serial ids have been tested in linux-next, the id additions should be fine as they are 'trivial'" * tag 'usb-4.6-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (25 commits) USB: option: add "D-Link DWM-221 B1" device id USB: serial: cp210x: Adding GE Healthcare Device ID USB: serial: ftdi_sio: Add support for ICP DAS I-756xU devices usb: dwc3: keystone: drop dma_mask configuration usb: gadget: udc-core: remove manual dma configuration usb: dwc3: pci: add ID for one more Intel Broxton platform usb: renesas_usbhs: fix to avoid using a disabled ep in usbhsg_queue_done() usb: dwc2: do not override forced dr_mode in gadget setup usb: gadget: f_midi: unlock on error USB: digi_acceleport: do sanity checking for the number of ports USB: cypress_m8: add endpoint sanity check USB: mct_u232: add sanity checking in probe usb: fix regression in SuperSpeed endpoint descriptor parsing USB: usbip: fix potential out-of-bounds write usb: renesas_usbhs: disable TX IRQ before starting TX DMAC transfer usb: renesas_usbhs: avoid NULL pointer derefernce in usbhsf_pkt_handler() usb: gadget: f_midi: Fixed a bug when buflen was smaller than wMaxPacketSize usb: phy: qcom-8x16: fix regulator API abuse usb: ch9: Fix SSP Device Cap wFunctionalitySupport type usb: gadget: composite: Access SSP Dev Cap fields properly ...

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus Felipe writes: usb: fixes for v4.6-rc3 We have two more fixes to f_midi. It should now behave much better. dwc3-keystone.c has gotten a fix which now allows it to work on keystone device when running in peripheral mode. A similar fix for DMA configuration was made for udc-core, too. We have a new PCI ID for Intel's Broxton platform. DWC3 can run on those platforms as well. And we also have some dwc2 got a fix for dr_mode usage, while renesas controller got 3 important fixes: a NULL pointer deref fix, IRQ <-> DMA race fix, and a fix to prevent a situation where we would queue a request to a disabled endpoint.
