[ ... ]Not sure if this is a valid conversion. Originally the driver would allocate a single buffer; with this buffer we have two distinct buffers. Given that this is used to download the microcode I'm not sure if this isn't a hardware-dependent structure which requires a single buffer including the sglist. Brian, can you shed some light here?The struct ipr_sglist is not a hardware defined data structure, so on initial glance, this should be OK. I'll load it up and give it a try to make sure it doesn't break code download.Hello Brian, Have you already obtained any test results?Bart, Yes. I tried this out on an ipr adapter and it looks fine.
