The code in 'syslib'=20 deals with items that are not directly related with the CPU cores=20 (arch/ppc/kernel) or with board issues (arch/ppc/platforms). Any code=20= that is generic for a number of systems should be in arch/ppc/syslib. =20= So code managing pci, interrupt controllers, generic system setup, etc=20= lives in arch/ppc/syslib. The transition predates my work with 2.6, I would guess that Paul M.=20 was influential in this change. If you are just doing a board port then your files should end up in=20 arch/ppc/platforms. It should be rare that you would need to touch=20 anything in arch/ppc/syslib. - kumar On Dec 24, 2004, at 11:05 AM, Povolotsky, Alexander wrote: > Hi, > > In Linux 2.6 I see the new directory arch/ppc/syslib, which does not=20= > exist > in Linux 2.4(.26). > I would GREATLY APPRECIATE if Tom or Dan (or someone else) could=20 > explain > what are the reasons for creating this new directory and describe on=20= > what > basis existing > Linux 2.4 files went there and why=A0 ... > and if there any new files (vs Linux 2.4) were created in that new=20 > directory > ?=A0 > > In general, I am seeking advise on porting PPC platform > (in my case it isvariant of 8xx ) from Linux 2.4.(.26) to Linux > 2.6(.10-rc3). > =A0Did anyone created howto document on this subject ? > > Thanks, > > Alex > _______________________________________________ > Linuxppc-embedded mailing list > Linuxppc-embedded@ozlabs.org > https://ozlabs.org/mailman/listinfo/linuxppc-embedded
