Detailed powertop measurements
More details:
I ran zap and vdr on a system that is idle. Without zap or vdr the system does about 5 wakups per second and spends about 0.1% of its time in C0 (cpu running).
Polling of the remote is disabled using the module option disable_rc_polling=1 for the dvb_usb module. The hardware PID filter is enabled with the option force_pid_filter_usage=1 for the same module.
vdr is the one from e-tobi.net/vdr-experimental lenny vdr-extensions here's the list of plugins that were enabled during the test: | Searching for plugins (VDR 1.6.0-2/1.6.0) (cache hit): epgsearch quickepgsearch conflictcheckonly live epgsearchonly ffnetdev streamdev-server.
MSI DigiVOX mini II rev.3
Compiled and installed according to the instructions on MSI_DigiVox_mini_II_V3.0.
The device has a hardware PID filter, but the maximum block size for transfers over USB seems to be limited to 512.
