One simple reason for me personally. I do not have the hardware and I am not particularly interested in it. I am interested only in cleaning up the smbus interface and moving ig4iic to iicbus. I want to get done with that as quickly as possible and my goal is just that the result is not worse than the current code. I am sure that people who are more interested than me can make the code much better. > On Mon, Oct 10, 2016 at 5:46 AM, Michael Gmelin <grembo@freebsd.org> wrote: >> On Mon, 10 Oct 2016 14:35:22 +0300 >> Andriy Gapon <avg@FreeBSD.org> wrote: >> >>> On 09/10/2016 23:22, Warner Losh wrote: >>>> There seems to be enough information present in the smbios data to >>>> know what devices are at what addresses.
