Does DspLink support Linux "suspend to ram"?

Filippo Ferrara

I'm working with dsplink_linux_1_65_00_02 on omap l138 and Linux (Texas distribution).

Echa time I run some application that uses dsplink library and try to put the system into "suspend to ram" state (ex by echo mem > /sys/power/state)
the system doesn't enter in suspension state (it says "2 tasks refusing to freeze").

Am I doing some error or dsplink channel have to closed before enter in suspension state?

Thank you

    I'm not an expert on this topic, but I am highly doubtful that the DSPLink driver supports any kind of power manangement features of the kind you describe.  I suspect that you would have to close any application actively using DSPLink (or at least have that application stop the use of the DSPLink) before a suspend operation can be completed.

    I'll see if I can get more details on this.
