On some platforms, root port has neither MSI/MSI-X nor INTx interrupt
generated in RC mode. In this case, we have to use other interrupt(e.g.
system shared interrupt) for port service irq to have AER, Hot-plug, etc,
services to work.

Hi Ira,
My comments inline.
Hi Ira and Dan,
Here is a introduction about my scenario of this case.
My case is use async_tx API to offload raid5,
Use fsl-talitos to compute parity calculation, fsl-dma to process memcpy.
What bug occurred to me?
Exception is thrown by BUG_ON(async_tx_ack_test(de

Freescale PPC chips.
There are, for unfortunate historical reasons, two nodes with a
compatible of "gianfar". One has a device_type of "network" and the

Default CCB on P3041 is 750MHz, but espi cannot work at 40MHz with this CCB,
so we need to slow down the clock rate of espi to 35MHz to make it work stable
with the CCB.
