Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

Annotated Snippet

config USB_PWC
	tristate "USB Philips Cameras"
	depends on VIDEO_DEV
	select VIDEOBUF2_VMALLOC
	help
	  Say Y or M here if you want to use one of these Philips & OEM
	  webcams:
	   * Philips PCA645, PCA646
	   * Philips PCVC675, PCVC680, PCVC690
	   * Philips PCVC720/40, PCVC730, PCVC740, PCVC750
	   * Philips SPC900NC
	   * Askey VC010
	   * Logitech QuickCam Pro 3000, 4000, 'Zoom', 'Notebook Pro'
	     and 'Orbit'/'Sphere'
	   * Samsung MPC-C10, MPC-C30
	   * Creative Webcam 5, Pro Ex
	   * SOTEC Afina Eye
	   * Visionite VCS-UC300, VCS-UM100

	  The PCA635, PCVC665 and PCVC720/20 are not supported by this driver
	  and never will be, but the 665 and 720/20 are supported by other
	  drivers.

	  Some newer logitech webcams are not handled by this driver but by the
	  Usb Video Class driver (linux-uvc).

	  The built-in microphone is enabled by selecting USB Audio support.

	  To compile this driver as a module, choose M here: the
	  module will be called pwc.

config USB_PWC_DEBUG
	bool "USB Philips Cameras verbose debug"
	depends on USB_PWC
	help
	  Say Y here in order to have the pwc driver generate verbose debugging
	  messages.
	  A special module options 'trace' is used to control the verbosity.

config USB_PWC_INPUT_EVDEV
	bool "USB Philips Cameras input events device support"
	default y
	depends on USB_PWC && (USB_PWC=INPUT || INPUT=y)
	help
	  This option makes USB Philips cameras register the snapshot button as
	  an input device to report button events.

	  If you are in doubt, say Y.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
