Hi all,
=20
I am working on evbmips port of NetBSD. The processor has 1 PCI DMA
controller and there is one more controller with 4 channels. This DMA is
shared between Serial i/o and ACLC controller.=20
=20
How can this be done?=20
The bus_space_dma framework is being initialized for PCI DMA
controller(single channel, dedicated). Can we have another instance of
bus_space_dma framework for the other controller? If yes then, in that
case how can we manage this sharing of DMA channels between Serial i/o
and ACLC.
=20
Regards,
Rishabh
