/* actually SetCpuFreq is used to determine if the system is in standby
|
|
this is an "elegant" hack, because:
|
|
* during a recording, cpu freq is kept "high", even if the box is sent to standby
|
|
* the "SetStandby" call is made even if a recording is running
|
|
On the TD, setting standby disables the frontend, so we must not do it
|
|
if a recording is running.
|
|
For now, the values in neutrino are hardcoded:
|
|
* f == 0 => max => not standby
|
|
* f == 50000000 => min => standby
