2024-02-17usb: gadget: functionfs: Add DMABUF import interfacePaul Cercueil
This patch introduces three new ioctls. They all should be called on a data endpoint (ie. not ep0). They are: - FUNCTIONFS_DMABUF_ATTACH, which takes the file descriptor of a DMABUF object to attach to the endpoint. - FUNCTIONFS_DMABUF_DETACH, which takes the file descriptor of the DMABUF to detach from the endpoint. Note that closing the endpoint's file descriptor will automatically detach all attached DMABUFs. - FUNCTIONFS_DMABUF_TRANSFER, which requests a data transfer from / to the given DMABUF. Its argument is a structure that packs the DMABUF's file descriptor, the size in bytes to transfer (which should generally be set to the size of the DMABUF), and a 'flags' field which is unused for now. Before this ioctl can be used, the related DMABUF must be attached with FUNCTIONFS_DMABUF_ATTACH. These three ioctls enable the FunctionFS code to transfer data between the USB stack and a DMABUF object, which can be provided by a driver from a completely different subsystem, in a zero-copy fashion.

2024-02-17usb: dwc3: gadget: Rewrite endpoint allocation flowThinh Nguyen
The driver dwc3 deviates from the programming guide in regard to endpoint configuration. It does this command sequence: DEPSTARTCFG -> DEPXFERCFG -> DEPCFG Instead of the suggested flow: DEPSTARTCFG -> DEPCFG -> DEPXFERCFG The reasons for this deviation were as follow, quoted: 1) The databook says to do %DWC3_DEPCMD_DEPSTARTCFG for every %USB_REQ_SET_CONFIGURATION and %USB_REQ_SET_INTERFACE (8.1.5). This is incorrect in the scenario of multiple interfaces. 2) The databook does not mention doing more %DWC3_DEPCMD_DEPXFERCFG for new endpoint on alt setting (8.1.6). Regarding 1), DEPSTARTCFG resets the endpoints' resource and can be a problem if used with SET_INTERFACE request of a multiple interface configuration. But we can still satisfy the programming guide requirement by assigning the endpoint resource as part of usb_ep_enable(). We will only reset endpoint resources on controller initialization and SET_CONFIGURATION request. Regarding 2), the later versions of the programming guide were updated to clarify this flow (see "Alternate Initialization on SetInterface Request" of the programming guide). As long as the platform has enough physical endpoints, we can assign resource to a new endpoint. The order of the command sequence will not be a problem to most platforms for the current implementation of the dwc3 driver. However, this order is required in different scenarios (such as initialization during controller's hibernation restore). Let's keep the flow consistent and follow the programming guide.
