Hi, I'm building a PCI driver and I'm in a fight with memory functions...maybe you can help me win? Here's the idea/problem: --- pciaddr = pci_resource_start(pcidev, 2); pcilen = pci_resource_len(pcidev, 2); --- That will, from BAR 2, give me the start address and length of my pci device memory. Now let's map this memory into kernel space (nocache): --- kernaddr = ioremap_nocache(pciaddr, pcilen); --- This should give me a _page aligned_ address in kernel virtual memory right? Still, I get kernaddr to be 0xF9282800, which is *half way* a 4K sized page! How can this be? I t should be page aligned shouldn't it? Can somebody help me? Thanks. -Kris PS. Extra information: pciaddr = 0xFEAFF800 pcilen = 0x00000400 -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
