2021-12-13drm/amdgpu: skip reset other device in the same hive if it's SRIOV VFZhigang Luo
On SRIOV, host driver can support FLR(function level reset) on individual VF within the hive which might bring the individual device back to normal without the necessary to execute the hive reset. If the FLR failed , host driver will trigger the hive reset, each guest VF will get reset notification before the real hive reset been executed. The VF device can handle the reset request individually in it's reset work handler. This change updated gpu recover sequence to skip reset other device in the same hive for SRIOV VF.

Move the cs_setup delay to the end of spi_set_cs. From include/linux/spi/spi.h: * @cs_setup: delay to be introduced by the controller after CS is asserted The cs_setup delay needs to happen *after* CS is asserted, that is, at the end of spi_set_cs, not at the beginning. Otherwise we're just delaying before the SPI transaction starts at all, which isn't very useful.

2021-12-13usb: gadget: u_ether: fix race in setting MAC address in setup phaseMarian Postevca
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().

Without the bound checks for scpi_pd->name, it could result in the buffer overflow when copying the SCPI device name from the corresponding device tree node as the name string is set at maximum size of 30. Let us fix it by using devm_kasprintf so that the string buffer is allocated dynamically.

`vaddr` is a pointer to unsigned char. sizeof(vaddr) here intends to get the size of a pointer. But readers may get confused. Change sizeof(vaddr) to sizeof(unsigned long) makes more sense.

2021-12-13usb: Introduce Xen pvUSB frontend (xen hcd)Juergen Gross
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 Nguyen
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.
