The bus supplies power to peripherals and allows for hot swapping. Up to 127 USB peripherals can be connected to a single USB host in a tree structure. The USB host is the root of the tree, the peripherals are the leaves and the inner nodes are special USB devices called hubs. Most PCs now have USB host ports, used to connect peripherals such as scanners, keyboards, mice, modems, cameras, disks, flash memory, network links, and printers to the PC. Say Y here if your computer has a host-side USB port and you want to use USB devices. You then need to say Y to at least one of the Host Controller Driver (HCD) options below. Choose a USB 1.1 controller, such as "UHCI HCD support" or "OHCI HCD support", and "EHCI HCD (USB 2.0) support" except for older systems that do not have USB 2.0 support. It doesn't normally hurt to select them all if you are not certain. If your system has a device-side USB port, used in the peripheral side of the USB protocol, see the "USB Gadget" framework instead. After choosing your HCD, then select drivers for the USB peripherals you'll be using. You may want to check out the information provided in and especially the links given in . To compile this driver as a module, choose M here: the module will be called usbcore. if USB source "drivers/usb/core/Kconfig" source "drivers/usb/mon/Kconfig" source "drivers/usb/wusbcore/Kconfig" source "drivers/usb/host/Kconfig" source "drivers/usb/renesas_usbhs/Kconfig" source "drivers/usb/class/Kconfig" source "drivers/usb/storage/Kconfig" source "drivers/usb/image/Kconfig" source "drivers/usb/usbip/Kconfig" endif source "drivers/usb/mtu3/Kconfig" source "drivers/usb/musb/Kconfig" source "drivers/usb/dwc3/Kconfig" source "drivers/usb/dwc2/Kconfig" source "drivers/usb/chipidea/Kconfig" source "drivers/usb/isp1760/Kconfig" comment "USB port drivers" if USB config USB_USS720 tristate "USS720 parport driver" depends on PARPORT select PARPORT_NOT_PC ---help--- This driver is for USB parallel port adapters that use the Lucent Technologies USS-720 chip. These cables are plugged into your USB port and provide USB compatibility to peripherals designed with parallel port interfaces. The chip has two modes: automatic mode and manual mode. In automatic mode, it looks to the computer like a standard USB printer. Only printers may be connected to the USS-720 in this mode. The generic USB printer driver ("USB Printer support", above) may be used in that mode, and you can say N here if you want to use the chip only in this mode. Manual mode is not limited to printers, any parallel port device should work. This driver utilizes manual mode. Note however that some operations are three orders of magnitude slower than on a PCI/ISA Parallel Port, so timing critical applications might not work. Say Y here if you own an USS-720 USB->Parport cable and intend to connect anything other than a printer to it.

The ULPI specification defines a standard set of registers that can be used to detect the vendor and product which allows ULPI to be handled as a bus. This module is the driver for that bus. The ULPI interfaces (the buses) are registered by the drivers for USB controllers which support ULPI register access and have ULPI PHY attached to them. The ULPI PHY drivers themselves are normal PHY drivers. ULPI PHYs provide often functions such as ADP sensing/probing (OTG protocol) and USB charger detection. To compile this driver as a module, choose M here: the module will be called ulpi. endif # USB_SUPPORT Makefile?id=e6e7b48b295afa5a5ab440de0a94d9ad8b3ce2d0'>e6e7b48b295afa5a5ab440de0a94d9ad8b3ce2d0 (diff)
drm/atomic: Fix double free in drm_atomic_state_default_clear
drm_atomic_helper_page_flip and drm_atomic_ioctl set their own events in crtc_state->event. But when it's set the event is freed in 2 places. Solve this by only freeing the event in the atomic ioctl when it allocated its own event. This has been broken twice. The first time when the code was introduced, but only in the corner case when an event is allocated, but more crtc's were included by atomic check and then failing. This can mostly happen when you do an atomic modeset in i915 and the display clock is changed, which forces all crtc's to be included to the state. This has been broken worse by adding in-fences support, which caused the double free to be done unconditionally.
