Re: [PATCH -mm v4 6/9] atmel_serial: Split the interrupt handler

[michael]

Hi,

All works now for me with preempt-rt. The problem is using hrtimer.

I think that hrtimer are executed with interrupts disabled so, if
this happen when I must receive a char, i have an overrun. The only
solution was the dma support to serial device.

Regards Michael
