Re: [Ocf-linux-users] infinite wait in mv_cesa (Marvell Kirkwood) icw cryptotest

[Harro H. <hr...@gm...>]

Some additional info,

When I define CESA_OCF_POLLING in cesa_ocf_drv.c everything works fine.

When I do "cat /proc/interrupts" (with #undef CESA_OCF_POLLING), I can
see that no cesa interrupts occurred. When I look at the debug output
(see previous mail) I do not see the line "cesa_interrupt_handler()"
either.

So for my configuration something is wrong/missing with my interrupts.
Any hints?

Thanks,

Harro
