I am just wondering if there is any way to check the DMA Channels that are allocated during runtime on a QNX 4.25 machine. Something like sin irq would be fine but I can’t find anything in that direction…
Check out rsrcdbmgr_query(). Of course, it is a cooperative system, so as long as the ISA driver used rsrcdbmgr_attach() to reserve the DMA resource you’re in luck…
