Linux version 2.6.14 (root@baldrick) (gcc version 4.0.2 20050808 (prerelease) (Ubuntu 4.0.1-4ubuntu9)) #1 Sun Oct 30 12:30:39 CET 2005
x86
Got this the moment I launched xawtv (using "grabdisplay"). The card is
a cheap and nasty wintv:
0000:00:08.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
Subsystem: Hauppauge computer works Inc. WinTV Series
Flags: bus master, medium devsel, latency 32, IRQ 20
Memory at dfbfe000 (32-bit, prefetchable) [size=4K]
Capabilities: <available only to root>
on a VIA chipset:
0000:00:00.0 Host bridge: VIA Technologies, Inc. VT8366/A/7 [Apollo KT266/A/333]
Subsystem: VIA Technologies, Inc.: Unknown device 0000
Flags: bus master, 66MHz, medium devsel, latency 0
Memory at e0000000 (32-bit, prefetchable) [size=128M]
Capabilities: <available only to root>
0000:00:01.0 PCI bridge: VIA Technologies, Inc. VT8366/A/7 [Apollo KT266/A/333 AGP] (prog-if 00 [Normal decode])
Flags: bus master, 66MHz, medium devsel, latency 0
Bus: primary=00, secondary=01, subordinate=01, sec-latency=0
I/O behind bridge: 0000c000-0000cfff
Memory behind bridge: dfc00000-dfcfffff
Prefetchable memory behind bridge: bfb00000-dfafffff
Capabilities: <available only to root>
I don't use overlay, since it always eventually manages to freeze the machine.
