pmppc7448/mv64x60 DMA from PCI to memory

Hi, I'm working on a project using this processor: http://www.artesyncp.com/products/PmPPC7448.html on a custom VME carrier, as shown below. We're wanting to suck large amounts of data from a PCI device which _cannot_ perform bus-mastered DMA (it is a PCI Target only). The Marvell Chip used by

question about linux with Xilinx ML-403

Dear Rick, First, thanks a lot for your information. However I still have something to ask. Our best recommendation is to use the drivers/net/xilinx_enet directory for the temac driver and just enable the Xilinx 10/100 Ethernet in menuconfig. I am not so clear with this. Do you mean that I

delay programming

That depends on how accurate you want. Sleep() functions can't be too accurate for Linux schedule characteristic. To get best accuracy, you can use hardware timer. udelay() is a choice which reduces the overall system performance. Best Regards, Leo -Original Message- From:
