i am working with a board of mpc8313 using default mpc8313erdb.dts. But i do not know how can i correctly use DMA to transport data from memory to a PCI device. i tryed this { ..... request_irq(IRQ,....); request_dma(.....); .... }
In request_irq() , i do not know what is the parameter IRQ. And , i did not find any words about DMA in mpc8313erdb.dts . So 1. please tell me what should be the parameter IRQ? Is it the irq requested when DMA initialized or another one? 2. If i want initialize DMA, how should i do with mpc8313erdb.dts? -- View this message in context: http://www.nabble.com/a-question-of-mpc8313%2C-maybe-simple-tp18067094p18067094.html Sent from the linuxppc-dev mailing list archive at Nabble.com. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
