Hi,
I need help and/or advice on the following problem:
New mainboard platfrom with latest chipset from a chipset vendor that can't do the job that we are asking for. The chipset (especially the SATA controller is supported in Kernel 2.6.24 and later.
The target market for those boards is using old fashioned distributions like CentOS, Debian, Fedora 8 openSUSE 10 and so on. So the gap is that the latest driver from 2.6.24 is not yet in those distributions. The impact of this is that the customer in the target market can't use the mainboards to run actual Linux distributions on them.
So there is a need ot backport e.g. the AHCI driver from 2.6.24 to 2.6.16 or 2.6.18. Doing a diff on the sources makes me think this is a sort of "mission impossible" since it sureley isn't just the ahci code that changed but also a lot in the kernel infrastructure meanwhile.
So what options do we have to help the customer? Changing to 2.6.24 kernel is not an option due to the customer. So it looks like the only way to "solve" this is a backport, but then we come to "who can do this?".
Any hints welcome and thanks a lot for your attention Rainer -- Dipl.-Inf. (FH) Rainer Koenig Project Manager Linux Business Clients Dept. IP BC E SW OS
