as steve mentioned earlier, the vmlinux kernel is not on the image and is loaded separately. you can see it in the directory listing you provided in an earlier email.
note that is just the binary, so you won't get any scheduling information out of it. if you want to modify the linux scheduler, you'll have to modify kernel code and recompile the binary yourself. see here: http://m5.eecs.umich.edu/wiki/index.php/Using_linux-dist_to_Create_Disk_Images_and_Kernels_for_M5 and here for linux patches and a precompiled cross compiler (if you don't want to create your own as described above). http://m5.eecs.umich.edu/wiki/index.php/Download as you can see, a lot of useful information is provided on the website, you'll probably save yourself a lot of time if you just go through it, then you won't have to wait on us for answers that are right there. we also have a tutorial and audio to go with it online that i think might be very helpful to you, loaded with information. lisa On Fri, May 9, 2008 at 11:04 AM, Mike Anderson <[EMAIL PROTECTED]> wrote: > Thanks, It works. > > I redownloaded it and mount it again according to FAQ. > > But, there is no linux kernel source files inside "linux-latest.img". > > Where to find out what scheduling algorithms that the disk image of m5 > simulator is > using to run the benchmarks ? > > thanks > > Mike > May 9 2008 > > > > Date: Thu, 8 May 2008 20:04:46 -0400 > > From: [EMAIL PROTECTED] > > > To: [email protected] > > Subject: Re: [m5-users] about m5term and linux kernel > > > > It looks like when you ran mke2fs you reformatted the image... > > > > I think there may be some confusion on how this is supposed to work. > > Basically, there are several layers of stuff going on here.
