I am using pci_alloc_consistent() for obtaining contiguous memory that is cache safe. Here is how I am calling the routine
pci_alloc_consistent(NULL,size,&dummy). Note I am throwing away the bus address. The memory that I get does not seem to be cache safe. My device doesn't see the data untill I add flush_dcache_range(..). It is very undesirable for me to add flushes and invalidates. I will appreciate any help in this matter. I am using kernel version 2.4.20-pre5 for IBM PPC405GP and using version 2.95.3 for gcc on an x86 as a cross compiler. I also have CONFIG_NOT_COHERENT_CACHE defined.
