I got the latest kernel source from kernel.org . I untarred it and did the following, linux-2.6.28> make menuconfig linux-2.6.28> make drivers/gpu/drm linux-2.6.28> make drivers/gpu/drm/drm.ko Now I got the files I needed, drm.ko & i915.ko. Unfortunately when I tried loading the modules I got an error like, error inserting 'drm.ko' : -1 Invalid module format I found out that this was because of version differences between the kernel I was using and the kernel with which I compiled the modules. I added the Jaunty repository and installed 2.6.28 into my Ubuntu. Now, when I run "uname -r" I get, 2.6.28-4-generic I still got the "Invalid module format" error with this, so I downloaded the kernel sources from the Ubuntu repository. As a result, I got the following 2 folders on my system, /usr/src/linux-headers-2.6.28-4 /usr/src/linux-headers-2.6.28-4-generic They appear to contain the kernel sources I need. In fact, I could run "make menuconfig" in both of them. (From what I can tell, the generic folder contains symbolic links for most of the directories & files to the other one) I copied the folders to my home directory and when I run, make drivers/gpu/drm I get this reply, make: Nothing to be done for `drivers/gpu/drm'. At this point, the .o files are not even created. Anyway, I then ran, make drivers/gpu/drm/drm.ko And here is the output I get, CHK include/linux/version.h CHK include/linux/utsrelease.h SYMLINK include/asm -> include/asm-x86 HOSTCC scripts/basic/fixdep HOSTCC scripts/basic/docproc HOSTCC scripts/basic/hash make[1]: *** No rule to make target `kernel/bounds.c', needed by `kernel/bounds.s'. Stop. make: *** [prepare0] Error 2 It's the same error no matter which of the above 2 folders I run the make from. This one really has me stumped. I've spent the whole weekend at this and not being able to compile the Ubuntu source when I can compile the kernel.org source is VERY frusterating. Any ideas on what I'm doing wrong ? Or did I miss a step somewhere ? Yours, Abru (Abraham Varricatt) ------------------------------------------------------------------------------ Check out the new SourceForge.net Marketplace.
