Review of Linux Compatibility

The Technotrend TT-budget C-1501 is a PCI DVB-C card that is supported under Linux since at least Kernel version 2.6.31 (e.g. since Ubuntu 9.10).

The card has the PCI-ID 13c2:101a, and is accessed by the kernel module budget_ci and identified in the following way by the Linux System:

02:05.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
	Subsystem: Technotrend Systemtechnik GmbH Device 101a
	Flags: bus master, fast Back2Back, medium devsel, latency 123, IRQ 17
	Memory at c3001000 (32-bit, non-prefetchable) [size=512]
	Kernel driver in use: budget_ci dvb
	Kernel modules: budget-ci

The kernel module loads automatically while providing the following log messages:

saa7146: register extension 'budget_ci dvb'.
budget_ci dvb 0000:02:05.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
DVB: registering new adapter (TT-Budget C-1501 PCI)
input: Budget-CI dvb ir receiver saa7146 (0) as /devices/pci0000:00/0000:00:1e.0/0000:02:05.0/input/input4
DVB: registering adapter 0 frontend 0 (Philips TDA10023 DVB-C)...
dvb_ca adapter 0: DVB CAM detected and initialised successfully


The C-1501 is provided together with a remote and infrared receiver. The receiver is recognized as “Input-Device”

input: DVB on-card IR receiver as /class/input/input4
input: Budget-CI dvb ir receiver saa7146 (1) as /class/input/input5

and hence can be used together with LIRC. The buttons of the remote can be used with the following LIRC configuration:
