Project 2.6 mipsel

This Page should be used to collect all the wisdom regarding compiling a working 2.6-kernel for the LS 2(mips).

All compiling information and information about patches should get here. if needed i can modify mediawiki to allow some more filetypes to be allowed to upload to the wiki. this way we could even share our patches directly here on this page.

Compiling a 2.4 Kernel


1) Build a 2.4.20-kernel from the gpl-source

(there you won`t need to apply the melfs.patch as this is obviously included)

we will test it by trying to load the resulting vmlinux.bin with the mips-loader.o

2) Create a patch for compiling a working LS2 Kernel from the vanilla kernel 2.4.20

After we know that we can build the kernel from GPL Source we need to find out what the differences are between the vanilla kernel and the GPL-Source Kernel. I tried to create a diff between those kernel-sources already (but i noticed that there are far too much lines in it as some lines have a "-" before and later a "+" for adding the unmodified again...maybe this is related to some additional blank lines or comments?

Here is a diff of the arch-tree between the vanilla 2.4.20 kernel and linux-2.4.20_mipsel_linkstation

and here is a complete kernel-diff

3) Build the latest 2.4-Kernel available

We should have a patch to create a LS2-kernel from the vanilla 2.4.20 kernel. Now we can try to create the latest 2.4-kernel available. currently this is (released on the 22.8.2006) 

Notes for everyone

do not forget to apply the melfs.patch because of the custom ext2_magic_number buffalo invented to protect the linux filesystem from is the melfs patch which takes care of that

Compiling a 2.6 Kernel

Currently there is no patch for that. As a starting point we want to find out whats the differences between the vanilla kernel 2.4.20 and the GPL-one. after creating a patch for that we want to create the latest 2.4 Kernel. after this has been accomplished we want to look at porting the 2.6-kernel to the LS2

Information about loader.o for the LS2

This should be possible....because Ejii coded the assembler stuff needed by loader.o because of the different CPU (mips instead of ppc) for this and he already compiled a kernel for that:
