The reason it has been so was that some ACPICA-related changes in Linux were not backported. I don't know why that happened, but that's something we need to be much more careful about in the future. Unfortunately, we sometimes need to make ACPICA changes in Linux urgently as bug fixes, so the workflow in which all changes would go through the ACPICA code base wouldn't be very practical. I think we need someone from your side to review proposed changes in Linux related to ACPICA and tell us which of them can be backported. If a Linux patch is ACKed by this person, it should be backported to the ACPICA code base timely, ideally as soon as it appears in the Linus' tree or after a major kernel release is made.

It has been very difficult for us to take Linux patches, backport and integrate into ACPICA, make additional changes, then forward port the final ACPICA changes to Linux, and then shoehorn the code into the original Linux patches. > > > > Difficult as in several times the work. > > > > Ming has worked very hard to forward-port the ACPICA code and then shoehorn the changes into the original Linux patches. > > > > But we can't do it this way again. > > > > We are open to suggestions on a better way to do this, perhaps Len can help. > > Well, I'm talking about a simple thing like splitting a patch into two pieces. > That's not going to take a lot of time IMO and the benefit is that more people > may actually understand what's being done. > > Moreover, if anyone hits a problem related to one of your patches, it's vital > to be able to figure out which change caused it to happen. > > Thanks, > Rafael > > > > -----Original Message----- > > From: Rafael J.
