Message-ID: <20020116202640.A485@earthlink.net> (raw)
About running the Andrea VM in 4M:
I booted in single user mode.
bash-2.05a# uname -a
Linux mountain 2.4.18pre2aa2 #1 Wed Jan 9 21:44:03 EST 2002 i586 unknown
bash-2.05a# dmesg| grep mem
Kernel command line: BOOT_IMAGE=2418p2aa2 ro root=1602 console=ttyS1,38400n8 single mem=4m
Memory: 2100k/4096k available (891k kernel code, 1608k reserved, 215k data, 196k init, 0k highmem)
Freeing unused kernel memory: 196k freed
Manually started syslogd, klogd and brought up the lo and eth0 interfaces and started sshd.
I can ssh into the box:

Running 4M is interesting. If I really wanted to run 4M, I'd use ash
for the shell, and try uClibc instead of glibc.
The test that really impresses me the most about 2.4.18pre2aa2 is what
I see on this test on an Athlon 1333 with 1024MB RAM:
simultaneously:
run continuous loop of mtest01 -p 85 -w # allocate and write to 85% of VM
create and cpio 10 330 MB files
nice -19 setiathome &
listen to mp3blaster # a few skips at the beginning, then smooth.
I've tested a bunch of kernels lately. This is only what's sitting in /boot
since I last cleaned it out:
mountain:/boot$ ls vml*
vmlinuz vmlinuz-2.4.17rc2aa2-old vmlinuz-2.4.18-pre3
vmlinuz-2.4.18pre2 vmlinuz-2.4.18pre3ll vmlinuz-2.5.1-dj11
vmlinuz-2.5.2-pre10 vmlinuz-2.5.2-pre9 vmlinuz-2.4.17
vmlinuz-2.4.17rc2aa2-wli vmlinuz-2.4.18-pre4 vmlinuz-2.4.18pre2aa1
vmlinuz-2.4.18pre3pe vmlinuz-2.5.1-dj13 vmlinuz-2.5.2-pre11
vmlinuz-2.5.2-pre9mingo vmlinuz-2.4.17-rmap11a vmlinuz-2.4.17rmap11b
vmlinuz-2.4.18pre1-mjc2nio vmlinuz-2.4.18pre2aa2 vmlinuz-2.4.18pre3pelb
vmlinuz-2.5.1-dj14 vmlinuz-2.5.2-pre5 vmlinuz.old
vmlinuz-2.4.17rc2aa2 vmlinuz-2.4.18-pre1 vmlinuz-2.4.18pre1mjc2
vmlinuz-2.4.18pre3-ac2 vmlinuz-2.5.1 vmlinuz-2.5.2
vmlinuz-2.5.2-pre6-mingo
IMHO, 2.4.18pre2aa2 is the best!
