NIC irq nobody cared ? virtual to physical and DMA questions
Hello List, This time the questions are different. Given the following output could anyone please tell me what is wrong ? In explicit what does that mysterious nobody cared message mean? And another stupid question: should DMA for a network card be enabled before or maybe _after_ interrupts get enabled? And... how to convert virtual address to physical one?

Hello Arjan, On 28th november 2005 (22:03:38) you wrote: oh it's *your own* netdev... Yes:-) Sorry for not being precise that makes things a lot easier ;) it's custom to have driver private data per net dev (see netdev_priv() to get it, alloc_etherdev() takes the size of it as argument). It's custom to make that private data a struct in which you can store the pci device pointer yourself, as well as any other per card data that you need to store Ok, I will do it like that then.

memory allocation for DMA operations from network interface
Hello List, My question is about DMA transfers from network device. I suspect these transfers require allocating physically contiguous memory blocks. What is the proper way to allocate such contiguous memory for DMA purposes inside the kernel? Also what is the proper and architecture independent way to convert virtual address to physical one? kind regards Mateusz Berezecki - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

atheros driver - desc
Hi list members, I just post the code for review for anyone interested. I would be more than pleased to hear some feedback from you on the code. Im sending a series of 8 patches splitted and diffed as in SubmittingPatches documentation. The driver is not yet fully working because I didn't finish kernel integration yet. Almost all driver I/O ops are reverse engineered independently of openbsd openhal which is missing just too much. Ok, enough talking. Most of the atheros 5212 hal is now open :) sending patches...
