Override enable bits may not be restored when going to low power mode (e.g. when in DWC2_POWER_DOWN_PARAM_NONE). These bits are set when probing/initializing drd (role switch). Restore them upon resume from low power mode (in case these have been lost). To achieve this, the last known role is restored upon resume. And the override enable bits are always set when configuring aval, bval and vbval. When resuming, forcing the role should be done only once, or this can cause port changes in HOST mode for instance. So, only restore FORCEDEVMODE/FORCEHOSTMODE when role_sw is unused Acked-by: Minas Harutyunyan <Minas.Harutyunyan@synopsys.com> Signed-off-by: Fabrice Gasnier <fabrice.gasnier@foss.st.com> Link: https://lore.kernel.org/r/1638806203-6624-4-git-send-email-fabrice.gasnier@foss.st.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2021-12-16usb: hub: avoid warm port reset during USB3 disconnectMathias Nyman1-5/+19
During disconnect USB-3 ports often go via SS.Inactive link error state before the missing terminations are noticed, and link finally goes to RxDetect state Avoid immediately warm-resetting ports in SS.Inactive state. Let ports settle for a while and re-read the link status a few times 20ms apart to see if the ports transitions out of SS.Inactive. According to USB 3.x spec 7.5.2, a port in SS.Inactive should automatically check for missing far-end receiver termination every 12 ms (SSInactiveQuietTimeout) The futile multiple warm reset retries of a disconnected device takes a lot of time, also the resetting of a removed devices has caused cases where the reset bit got stuck for a long time on xHCI roothub. This lead to issues in detecting new devices connected to the same port shortly after.

In current design, when the tcpm port is unregisterd, the kthread_worker will be destroyed in the last step. Inside the kthread_destroy_worker(), the worker will flush all the works and wait for them to end. However, if one of the works calls hrtimer_start(), this hrtimer will be pending until timeout even though tcpm port is removed. Once the hrtimer timeout, many strange kernel dumps appear. Thus, we can first complete kthread_destroy_worker(), then cancel all the hrtimers. This will guarantee that no hrtimer is pending at the end.

2021-12-14USB: serial: cp210x: fix CP2105 GPIO registrationJohan Hovold1-2/+4
When generalising GPIO support and adding support for CP2102N, the GPIO registration for some CP2105 devices accidentally broke. Specifically, when all the pins of a port are in "modem" mode, and thus unavailable for GPIO use, the GPIO chip would now be registered without having initialised the number of GPIO lines. This would in turn be rejected by gpiolib and some errors messages would be printed (but importantly probe would still succeed). Fix this by initialising the number of GPIO lines before registering the GPIO chip. Note that as for the other device types, and as when all CP2105 pins are muxed for LED function, the GPIO chip is registered also when no pins are available for GPIO use.

2021-12-13usb: gadget: u_ether: fix race in setting MAC address in setup phaseMarian Postevca1-10/+6
When listening for notifications through netlink of a new interface being registered, sporadically, it is possible for the MAC to be read as zero. The zero MAC address lasts a short period of time and then switches to a valid random MAC address. This causes problems for netd in Android, which assumes that the interface is malfunctioning and will not use it. In the good case we get this log: InterfaceController::getCfg() ifName usb0 hwAddr 92:a8:f0:73:79:5b ipv4Addr 0.0.0.0 flags 0x1002 In the error case we get these logs: InterfaceController::getCfg() ifName usb0 hwAddr 00:00:00:00:00:00 ipv4Addr 0.0.0.0 flags 0x1002 netd : interfaceGetCfg("usb0") netd : interfaceSetCfg() -> ServiceSpecificException (99, "[Cannot assign requested address] : ioctl() failed") The reason for the issue is the order in which the interface is setup, it is first registered through register_netdev() and after the MAC address is set. Fixed by first setting the MAC address of the net_device and after that calling register_netdev().

Introduces the Xen pvUSB frontend. With pvUSB it is possible for a Xen domU to communicate with a USB device assigned to that domU. The communication is all done via the pvUSB backend in a driver domain (usually Dom0) which is owner of the physical device. The pvUSB frontend is a USB hcd for a virtual USB host connector. The code is taken from the pvUSB implementation in Xen done by Fujitsu based on Linux kernel 2.6.18. Changes from the original version are: - port to upstream kernel - put all code in just one source file - move module to appropriate location in kernel tree - adapt to Linux style guide - minor code modifications to increase readability Signed-off-by: Juergen Gross <jgross@suse.com> Link: https://lore.kernel.org/r/20211123132048.5335-3-jgross@suse.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2021-12-13usb: dwc3: gadget: Support Multi-Stream TransferThinh Nguyen2-5/+30
Synopsys introduced a new enhancement to DWC_usb32 called Multi-Stream Transfer (MST) to improve bulk streams performance for SuperSpeed and SuperSpeed Plus. This enhancement allows the controller to look ahead and process multiple bulk streams. Previously, to initiate a bulk stream transfer, the driver has to issue Start Transfer command and wait for the stream to complete before initiating a new stream. As a result, the controller does not process TRBs beyond a single stream. With the enhancement, as long as there are new requests, the dwc3 driver can keep preparing new TRBs and the controller can keep caching and processing them without waiting for the transfer completion. The programming flow is similar to regular bulk endpoint with a few additional rules: 1) Chained TRBs of the same stream must have a matching stream ID 2) The last TRB of a stream must have CHN=0 3) All the TRBs with LST=0 must have CSP=1 Depends on the application and usage, internal tests show significant performance improvement in UASP transfers with this enhancement.

2021-12-10xhci: avoid race between disable slot command and host runtime suspendMathias Nyman3-8/+16
Make xhci_disable_slot() synchronous, thus ensuring it, and xhci_free_dev() calling it return after xHC controller completes the disable slot command. Otherwise the roothub and xHC host may runtime suspend, and clear the command ring while the disable slot command is being processed. This causes a command completion mismatch as the completion event can't be mapped to the correct command. Command ring gets out of sync and commands time out. Driver finally assumes host is unresponsive and bails out. usb 2-4: USB disconnect, device number 10 xhci_hcd 0000:00:0d.0: ERROR mismatched command completion event ... xhci_hcd 0000:00:0d.0: xHCI host controller not responding, assume dead xhci_hcd 0000:00:0d.0: HC died; cleaning up Cc: <stable@vger.kernel.org> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20211210141735.1384209-3-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2021-12-10xhci: Remove CONFIG_USB_DEFAULT_PERSIST to prevent xHCI from runtime suspendingKai-Heng Feng1-4/+0
When the xHCI is quirked with XHCI_RESET_ON_RESUME, runtime resume routine also resets the controller. This is bad for USB drivers without reset_resume callback, because there's no subsequent call of usb_dev_complete() -> usb_resume_complete() to force rebinding the driver to the device. For instance, btusb device stops working after xHCI controller is runtime resumed, if the controlled is quirked with XHCI_RESET_ON_RESUME. So always take XHCI_RESET_ON_RESUME into account to solve the issue.

2021-12-09Revert "usb: dwc3: dwc3-qcom: Enable tx-fifo-resize property by default"Douglas Anderson1-15/+0
This reverts commit cefdd52fa0455c0555c30927386ee466a108b060. On sc7180-trogdor class devices with 'fw_devlink=permissive' and KASAN enabled, you'll see a Use-After-Free reported at bootup. The root of the problem is that dwc3_qcom_of_register_core() is adding a devm-allocated "tx-fifo-resize" property to its device tree node using of_add_property(). The issue is that of_add_property() makes a _permanent_ addition to the device tree that lasts until reboot. That means allocating memory for the property using "devm" managed memory is a terrible idea since that memory will be freed upon probe deferral or device unbinding. Let's revert the patch since the system is still functional without it. The fact that of_add_property() makes a permanent change is extra fodder for those folks who were aruging that the device tree isn't really the right way to pass information between parts of the driver. It is an exercise left to the reader to submit a patch re-adding the new feature in a way that makes everyone happier.
