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.

	  Support for external USB adapters designed by Technotrend and
	  produced by Hauppauge, shipped under the brand name 'DEC2000-t'
	  and 'DEC3000-s'.

	  Even if these devices have a MPEG decoder built in, they transmit
	  only compressed MPEG data over the USB bus, so you need
	  an external software decoder to watch TV on your computer.

	  This driver needs external firmware. Please use the commands
	  "<kerneldir>/scripts/get_dvb_firmware dec2000t",
	  "<kerneldir>/scripts/get_dvb_firmware dec2540t",
	  "<kerneldir>/scripts/get_dvb_firmware dec3000s",
	  download/extract them, and then copy them to /usr/lib/hotplug/firmware
	  or /lib/firmware (depending on configuration of firmware hotplug).

	  Say Y if you own such a device and want to use it.

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.
