In Synopsys's dwc3 data book: To avoid underrun and overrun during the burst, in a high-latency bus system (like USB), threshold and burst size control is provided through GTXTHRCFG and GRXTHRCFG registers. In Realtek DHC SoC, DWC3 USB 3.0 uses AHB system bus. When dwc3 is connected with USB 2.5G Ethernet, there will be overrun problem. Therefore, setting TX/RX thresholds can avoid this issue.

Realtek DHC RTD SoCs integrate dwc3 IP and has some customizations to support different generations of SoCs. The RTD1619b subclass SoC only supports USB 2.0 from dwc3. The driver can set a maximum speed to support this. Add role switching function, that can switch USB roles through other drivers, or switch USB roles through user space through set /sys/class/usb_role/.

Displayport Alternatemode 2.1 requires cable capabilities such as cable signalling, cable type, DPAM version which then will be used by mux driver for displayport configuration.

Displayport Alternate mode 2.1 requires configuration for additional cable details such as signalling for cable, UHBR13.5 Support, Cable type and DPAM version. These details can be used with mux drivers to configure SOP DP configuration for Displayport Alternate mode 2.1.

The uvc_video_enable function is calling cancel_work_sync which will be blocking as long as new requests will be queued with the while loop. To ensure an earlier stop in the pumping loop in this particular case we rework the worker to requeue itself on every requests. Since the worker is already running prioritized, the scheduling overhad did not have real impact on the performance.

The uvc_video_enable function of the uvc-gadget driver is dequeing and immediately deallocs all requests on its disable codepath. This is not save since the dequeue function is async and does not ensure that the requests are left unlinked in the controller driver. By adding the ep_free_request into the completion path of the requests we ensure that the request will be properly deallocated.

In _dwc2_hcd_urb_enqueue(), "urb->hcpriv = NULL" is executed without holding the lock "hsotg->lock". In _dwc2_hcd_urb_dequeue(): spin_lock_irqsave(&hsotg->lock, flags); ... if (!urb->hcpriv) { dev_dbg(hsotg->dev, "## urb->hcpriv is NULL ##\n"); goto out; } rc = dwc2_hcd_urb_dequeue(hsotg, urb->hcpriv); // Use urb->hcpriv ... out: spin_unlock_irqrestore(&hsotg->lock, flags); When _dwc2_hcd_urb_enqueue() and _dwc2_hcd_urb_dequeue() are concurrently executed, the NULL check of "urb->hcpriv" can be executed before "urb->hcpriv = NULL". After urb->hcpriv is NULL, it can be used in the function call to dwc2_hcd_urb_dequeue(), which can cause a NULL pointer dereference. This possible bug is found by an experimental static analysis tool developed by myself. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations. The above possible bug is reported, when my tool analyzes the source code of Linux 6.5. To fix this possible bug, "urb->hcpriv = NULL" should be executed with holding the lock "hsotg->lock". After using this patch, my tool never reports the possible bug, with the kernelconfiguration allyesconfig for x86_64. Because I have no associated hardware, I cannot test the patch in runtime testing, and just verify it according to the code logic.

Currently did varaible is used for HW differences between the devices which complicates the code by adding checks. Therefore it is better to convert enum->pointer for data match and extend match support for both ID and OF tables by using i2c_get_match_data(). Add struct rt1711h_chip_info with did variable and replace did->info in struct rt1711h_chip. Later patch will add more hw differences to struct rt1711h_chip_info and avoid checking did for HW differences.

Drivers must not reference functions marked with __exit as these likely are not available when the code is built-in. There are few creative offenders uncovered for example in ARCH=amd64 allmodconfig builds. So only trigger the section mismatch warning for W=1 builds. The dual rule that drivers must not reference .init.* is implemented since commit 0db25245 ("modpost: don't allow *driver to reference .init.*") which however missed that .exit.* should be handled in the same way. Thanks to Masahiro Yamada and Arnd Bergmann who gave valuable hints to find this improvement.
