Re: how to allocate 9MB of memory in kernel ?

Hi all ... I am uploading the source code which is doing the following :- 1. mapping cpld register using ioremap coping the data to circular buffer and remapping it to user space . 2. It can also map kernel virtual dma memory to user space if compiled conditionally . following is the problem

Xilinx Linux 2.6 for XPS LL_TEMAC and LL_FIFO problem

Dear All, I have done a design using EDK 8.2 using Hard_Temac IP component. In the EDK 9.2 there is a new idea to use ll_temac in conjunction with ll_fifo or ll_dma. So far I was using happily the linux kernel by Grant Likey. Unfortunately it does not deal with ll_temac. I have download the

RE: Xilinx Linux 2.6 for XPS LL_TEMAC and LL_FIFO problem

Mirek, I'm currently using the driver (CONFIG_XILINX_LLTEMAC) with the DMA portion with no problem, which is what you kind of eluded to. From what I've seen, the drver source does support the FIFO portion. It just relies on having the proper definition for the TEMAC in either the DTS or the

RE: Xilinx Linux 2.6 for XPS LL_TEMAC and LL_FIFO problem

Hi Mirek, We are not currently testing the LL TEMAC driver with the LL FIFO. We only test with the DMA configuration. I also realize this may not be documented that well and we may need to work on that. Our reasoning is that in the Virtex5 FXT devices the DMA is hard so that it does not cost any
