xhci: add quirk for host controllers that don't update endpoint DCS

2021-10-27T07:56:46+00:00

commit 5255660b208aebfdb71d574f3952cf48392f4306 upstream. Seen on a VLI VL805 PCIe to USB controller. For non-stream endpoints at least, if the xHC halts on a particular TRB due to an error then the DCS field in the Out Endpoint Context maintained by the hardware is not updated with the current cycle state. Using the quirk XHCI_EP_CTX_BROKEN_DCS and instead fetch the DCS bit from the TRB that the xHC stopped on.

usb: musb: dsps: Fix the probe error path

2021-10-20T09:45:00+00:00

commit c2115b2b16421d93d4993f3fe4c520e91d6fe801 upstream. Commit 7c75bde329d7 ("usb: musb: musb_dsps: request_irq() after initializing musb") has inverted the calls to dsps_setup_optional_vbus_irq() and dsps_create_musb_pdev() without updating correctly the error path. dsps_create_musb_pdev() allocates and registers a new platform device which must be unregistered and freed with platform_device_unregister(), and this is missing upon dsps_setup_optional_vbus_irq() error. While on the master branch it seems not to trigger any issue, I observed a kernel crash because of a NULL pointer dereference with a v5.10.70 stable kernel where the patch mentioned above was backported. With this kernel version, -EPROBE_DEFER is returned the first time dsps_setup_optional_vbus_irq() is called which triggers the probe to error out without unregistering the platform device. Unfortunately, on the Beagle Bone Black Wireless, the platform device still living in the system is being used by the USB Ethernet gadget driver, which during the boot phase triggers the crash. My limited knowledge of the musb world prevents me to revert this commit which was sent to silence a robot warning which, as far as I understand, does not make sense. The goal of this patch was to prevent an IRQ to fire before the platform device being registered. I think this cannot ever happen due to the fact that enabling the interrupts is done by the ->enable() callback of the platform musb device, and this platform device must be already registered in order for the core or any other user to use this callback. Hence, I decided to fix the error path, which might prevent future errors on mainline kernels while also fixing older ones.

xhci: Enable trust tx length quirk for Fresco FL11 USB controller

2021-10-20T09:45:00+00:00

commit ea0f69d8211963c4b2cc1998b86779a500adb502 upstream. Tested on SD5200T TB3 dock which has Fresco Logic FL1100 USB 3.0 Host Controller. Before this patch streaming video from USB cam made mouse and keyboard connected to the same USB bus unusable. Also video was jerky. With this patch streaming video doesn't have any effect on other periferals and video is smooth.

xhci: Fix command ring pointer corruption while aborting a command

2021-10-20T09:45:00+00:00

commit ff0e50d3564f33b7f4b35cadeabd951d66cfc570 upstream. The command ring pointer is located at [6:63] bits of the command ring control register (CRCR). All the control bits like command stop, abort are located at [0:3] bits. While aborting a command, we read the CRCR and set the abort bit and write to the CRCR. The read will always give command ring pointer as all zeros. So we essentially write only the control bits. Since we split the 64 bit write into two 32 bit writes, there is a possibility of xHC command ring stopped before the upper dword (all zeros) is written. If that happens, xHC updates the upper dword of its internal command ring pointer with all zeros. Next time, when the command ring is restarted, we see xHC memory access failures. Fix this issue by only writing to the lower dword of CRCR where all control bits are located.
