Hello, I would like to know if it is safe to use the BUS_DMA_WAITOK flag with bus_dmamem_alloc(), in the context of the device_attach routine? Many drivers use BUS_DMA_NOWAIT.
I need a 32Ko buffer and on low memory my driver cannot attach (bus_dmamem_alloc returns ENOMEM). Will BUS_DMA_WAITOK help in this case? Thanks in advance, regards. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[email protected]"
