Re: [Wlug] New ULTRA1 success - almost

by Adam Gomes

Ahhh ... one lovely advantage to Sparc, is that it doesn't have the same silly size limitations that x86 does. So ... _don't_ worry about the size of the kernel. If you have room in memory, it will load. In fat, my own kernel on my Ultra 10 is 3.3MB. That's one reason why there is no "make zImage" for sparc. Of course, a smaller kernel means lower memory utilization, and that of course has its own benefits, but it's not necessary to do all that slimming that is needed for x86. Also, if you want to save some space on your disk, at the cost of a little bit of speed at boot time, you can just gzip -9 your kernel. I did this, myself. The SILO boot loader is smart enough to notice that it is a gzipped image and just decompress it itself. See on my own machine: gomer@callisto:/boot$ ls -l vmlinuz* lrwxrwxrwx 1 root root 20 May 18 2005 vmlinuz -> vmlinuz-2.4.18-sun4u -rw-r--r-- 1 root root 1379575 May 18 2005 vmlinuz-2.4.18-sun4u gomer@callisto:/boot$ file vmlinuz-2.4.18-sun4u vmlinuz-2.4.18-sun4u: gzip compressed data, was "vmlinux", from Unix, max compression gomer@callisto:/boot$ cp vmlinuz-2.4.18-sun4u ~/kernel.gz gomer@callisto:~$ gzip -d kernel.gz gomer@callisto:~$ ls -l kernel -rw-r--r-- 1 gomer gomer 3371524 Apr 15 09:06 kernel gomer@callisto:~$ file kernel kernel: ELF 64-bit MSB executable, SPARC V9, version 1 (SYSV), statically linked, not stripped (not even stripped), lol. So, please, don't lose any sleep over the size of your Kernel ... not on Sparc64 at least. --Adam On Fri, 2007-04-13 at 17:51 -0400, Eric Martin wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > I realize I may need to qualify my last post. by 'Make as many modules > as possible' I meant what Mike said.

I built a no-module kernel using all the hardware I knew I had and gzipped it, it ended up being a tad over 1 MB for my Ultra 2-specific 2.4.34, and had no problem firing up from SILO. Dmesg will give (the OP) a pretty good idea of what the generic kernel is seeing. Brian J. Conway

New ULTRA1 success - almost

by ken jones

I have succeeded in compiling Gentoo Linux-2.4.34-sparc kernel on my new ULTRA1. This machine-toy has kept me off the streets and out of trouble for the last couple days. (The weather has been cooperative toward the same end.) I have a question. The Gentoo instructions <http://www.gentoo.org/doc/en/handbook/handbook-sparc.xml?part=1&chap=7#comp…> tell me that if my kernel is too big that it might not boot. "If the (uncompressed) size is bigger than 2.5 MB (for Sparc32) or 3.5 MB (for Sparc64), reconfigure your kernel until it doesn't exceed these limits. One way of accomplishing this is by having most kernel drivers compiled as modules. Ignoring this can lead to a non-booting kernel." My kernel after a strip command is still 3.7M. -----------snip from command line after a strip command----------- (chroot) livecd linux # strip -R .comment -R .note vmlinux (chroot) livecd linux # ls -lh vmlinux -rwxr-xr-x 1 root root 3.7M Apr 13 06:03 vmlinux --------------end snip---------------- Should I take this warning seriously? How do I figure out which drivers to deselect from menuconfig? lspci gives me no response. I am not sure what is in my machine. Ken Jones

Yes, Saturday April 21 for electronics drop off. There is no limit, but they will question you probably if you bring a lot of stuff. Also, they will (I was told) check your vehicle registration to make sure you are a Worcester resident. --- Eric Martin <freak4uxxx(a)gmail.com> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Sunday, April 21 between 9 and 3 metech will be > accepting all > electronics including Computers, monitors, tvs, > LCDs, printers other > computer related equipment, stereos, cells, VCRs, > microwaves, and other > household electronics.
