And the kernel will blow up in flames under various funny circumstances and you'll lose a fair amount of performances. The 6xx kernel requires at least the IBAT mapping the kernel text. Some of the exception handling code path can't deal with getting a hash fault at critical locations (they can mostly deal with data hash misses nowadays, but the code has to be accessible at all times). > > ... but I guess I have to setup my own page table for the reserved > > DMA memory area and implement my own alloc_pages() function!? > > No, that's already done for you behind all of these functions. > > Thanks. > > -- Dan > > -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
