It's actually linuxppc-2.5, the "old" linuxppc_2_5 tree was used when Linus didn't us bk, it's no longer maintained. > linuxppc_2_4 is the stable PowerPC specific 2.4 tree (all, or the > majority, of which has been merged into Marcelo's 2.4 tree, I think). Mostly. A few newer stuffs that didn't make it into Marcelo's 2.4 are there. > linuxppc_2_4_devel is where any remaining 2.4-specific development by > Cort is going on, and linuxppc_2_4_benh is Ben's tree (where the really > experimental stuff is).

Actually, Cort is no longer maintaining PPC trees. linuxppc_2_4_devel contains support for more boards and is (slowly) beeing merged into linuxppc_2_4 and Marcelo as well. It was used as a playground for new developements when 2.5 wasn't started yet, and is used for new board support in 2.4 before it's ready for the stable tree. My rsync kernel (also available as patches against official 2.4 on ftp.kernel.org) is based on linuxppc_2_4. It contains additional cutting-edge support for PowerMac machines. It's not really experimental any more, but some stuffs here didn't make it into the other trees yet for various reasons. I also have a kernel for experimental stuffs, but I don't advertise it to avoid adding more confusion ;) Note that the current maintainer of the entire PPC architecture is Paul Mackerras (Cort resigned a while ago). I maintain the PowerMac support, and various other people are involved in support for the bazillion of boards/platforms supported by the PPC kernel. -- Benjamin Herrenschmidt <[EMAIL PROTECTED]>
