Conky 1.7.2 on OpenSolaris

I've tried to compile the last Conky 1.7.2 version with Lua Cairo bindings on OpenSolaris and should say it impress me. It was necessary to tinker with code a little but I liked the result.



I hope to prepare clean patch soon.

Installing OpenSolaris on a Sparc using LiveCD

I've written a sample installation script for Sparc snv125 LiveCD. Taking as basis my "zfsinstall" script for MilaX Sparc LiveCD and improving some hacks for BE, I've now a working OpenSolaris system on my old Ultra 60, with possibility for next upgrading.
Required steps:
1. Boot from LiveCD. (After booting I disabled some services like AI,LDOM which are not necessary on my Ultra).
2. Configure network (plumb interface and enable ssh).
3. Download and run zfsinstall_sparc script (i.e. ./zfsinstall_sparc c4t1d0s0)
4. Reboot.

Sample output:

root@opensolaris:/jack# ./zfsinstall c4t1d0s0
Test TI started in real mode...
Target type specified: BE
BE target prepared successfully
BE target created successfully
Starting to copy data from UFS root to /zfsroot - this may take some time.

OpenSolaris Sparc snv125 LiveCD

Following numerous requests from users I've prepared Sparc LiveCD based on osol-1002-125-ai-sparc.iso (see my previous post). Please remember that this iso is UNOFFICIAL version, I've created it only for my tests. With this iso you can test OpenSolaris on your hardware, AI tools or you can install system from this LiveCD manually, using steps from my old posts (i.e. you need to create zpool, copy all LiveCD contents to rootfs, disable live-media services, change vfstab and etc).
Temporarily iso is here.

How to make a sparc Live CD from AI

That's what I did to get the LiveCD from last AI iso.
On sparc machine:

# mkdir -p /opt/livecd/s0.
# mount -F hsfs `lofiadm -a osol-1002-122-ai-sparc.iso` /mnt

I copied all iso's content to s0 and then I've unpacked /opt/livecd/s0/boot/boot_archive with root_archive to /opt/livecd/tmp.
Next:

# cd /opt/livecd/tmp
# echo snv122 > .volumeid
# mv .autoinstall .livecd

I've also removed last block about keyboard configuration and gdm in /lib/svc/method/live-fs-root.
Next I've created lofi directory in /opt/livecd/tmp/dev and symlink in this directory to ../../devices/pseudo/lofi@0:1 (this is required for mounting solaris.zlib).
I took hsfs.bootblock from SXCE DVD and put it in boot directory.

# cd /opt/livecd/s0/boot/
# root_archive pack boot_archive /opt/livecd/tmp

Script root_archive required small hack for boot-archive size - I've added line "size=130000" before "/usr/sbin/mkfile ${size}k "$TMR".
Next I've created symlinks for boot_archive in /opt/livecd/s0/platform/sun4v and /opt/livecd/s0/platform/sun4u
Now iso:

# cd /opt/livecd/
# mkisofs -G s0/boot/hsfs.bootblock -B ... -l -ldots -R -N -D -V snv122 -o /opt/sparc_snv122.iso s0/

Live CD boots on my old Ultra 60 (you can see some warnings and services errors but that's another story):

Minimal OpenSolaris SPARC install

Using previous instructions I've successfully installed opensolaris 2009.06 on my TestFarm (thanks, Jim) T2000 from existing Nevada b98.
Steps are identical: my machine have 4 disks, so I've prepared third disk (c0t2d0) for installation (I take 4gb):

Part Tag Flag Cylinders Size Blocks
0 root wm 0 - 824 4.00GB (825/0/0) 8395200
1 unassigned wm 0 0 (0/0/0) 0
2 backup wu 0 - 14086 68.35GB (14087/0/0) 143349312
3 unassigned wm 0 0 (0/0/0) 0
4 unassigned wm 0 0 (0/0/0) 0
5 unassigned wm 0 0 (0/0/0) 0
6 unassigned wm 0 0 (0/0/0) 0
7 unassigned wm 0 0 (0/0/0) 0

Next steps (it's fast):

zpool create opensolaris c0t2d0s0
zfs create opensolaris/rootfs
zfs set compression=on opensolaris/rootfs
zfs set mountpoint=legacy opensolaris/rootfs
mkdir /zfsroot
mount -f zfs opensolaris/rootfs /zfsroot

Get detailed disk info with Caiman libraries

Using Caiman libraries you can write small programs which can be very useful in sysadmin's daily work or can help making your own installer. For example, using libtd (Target Discovery) library you can get info about system disks and partitions very fast. Here's an example of using libtd test program (test_td):

# ./test_td -d
Disk discovery
Total number of disks: 3
---------------------------------
num | name| ctype|size [MB]|
---------------------------------
1 | c2t0d0| usb| 976|
2 | c0d0| ata| 76350|
3 | c1d0| ata| 38166|
---------------------------------

# ./test_td -p all
Partition discovery for all disks
-------------------------------------
num | name| active| ID| lswp|
-------------------------------------
1 | c2t0d0p1| Yes| BF| No|
2 | c0d0p1| Yes| BF| No|
3 | c1d0p3| No| 83| No|
4 | c1d0p2| Yes| 83| No|
5 | c1d0p1| No| 82| Yes|
-------------------------------------

Now verbose output:

# ./test_td -d -v
Disk discovery
Total number of disks: 3
-------------------------------------------------------------------------------
num | name| vendor| ctype| mtype| rem| lbl| bsize|#of blocks|size [MB]|

3 | c1d0| unknown| ata| FIXED| No| VF| 512| 78164352| 38166|
-------------------------------------------------------------------------------

# ./test_td -p all -v

---------------------------------------------------------------------
num | name| active| ID| lswp| 1st block|#of blocks|size [MB]|
---------------------------------------------------------------------
1 | c2t0d0p1| Yes| BF| No| 2048| 1996800| 975|

Busybox on OpenSolaris ARM

After some steps I've got busybox running on OpenSolaris ARM under Qemu:



And here's the output I get from booting in debug mode (look how modstatic loads modules).

First OpenSolaris ARM release

Great news from OpenSolaris ARM Port project: first OS release for ARM platform is now available. This release support NEC Electronics's NaviEngine 1 (NE1) and has some interesting features: genunix, unix and required device drivers are statically linked at building time as vmunix to save the startup time, zfs is modified to save the runtime memory.


So I hope that after some time we'll see OpenSolaris powered PDA.

Minimizing SunStudio

SunStudio Express uses ~900 mb on my Nevada. But for building usual C app I need only small part of SS. For example I used only these files for building imlib2 (I tried various flags):

# cd /opt/SUNWspro; find .
.
./lib
./lib/crt1x.o
./lib/crti.o
./lib/sys
./lib/sys/libyabe.so
./lib/sys/lib_I_quad.so
./lib/sys/libsunir.so
./lib/sys/liblni.so.1
./lib/libdwarf.so
./lib/crt1.o
./lib/libmopt.a
./lib/libdwarf.so.1
./lib/lib_I_dbg_gen.so.1
./lib/values-xa.o
./lib/libm.il
./lib/lib_I_dbg_gen.so
./lib/crtn.o
./bin
./bin/iropt
./bin/fbe
./bin/cc
./bin/ir2hf
./bin/ube
./bin/acomp

# du -hs
19M .

Of course you also need headers for successful compilation, but referring to cc if space is important factor for you - 19 is not 900, right?

Minimal OpenSolaris network install script

While preparing new version of zfsinstall, I've written sample version for minimal OpenSolaris installation over network. This script also includes disk partitioning. If complete installation is needed just replace pkg list with:

entire
SUNWcsd
SUNWcs

Try it if you've problems with graphics on old laptops and you can't run GUI installer.
You can find osinstaller script in MilaX mercurial repository on OpenSolaris.org.

Busybox on OpenSolaris

I hacked busybox and now it's working on my Solaris machine. This is not very fresh version (1.2.0) because all last releases become more Linux-specific. I've removed some applets and added "df","init","mount","umount","ps" from Solaris. Network applets like "ifconfig" are currently not implemented. For embedded Solaris we need native "ifconfig" with "plumb" function.

~$ uname -a
SunOS sysadm 5.11 snv_110 i86pc i386 i86pc
~$ ./busybox
BusyBox v1.2.0 (2009.04.20-10:06+0000) multi-call binary

Usage: busybox [function] [arguments]...
or: [function] [arguments]...

BusyBox is a multi-call binary that combines many common Unix
utilities into a single executable. Most people will create a
link to busybox for each function they wish to use and BusyBox
will act like whatever it was invoked as!

Currently defined functions:
[, [[, awk, bunzip2, busybox, bzcat, cat, chgrp, chmod, chown, chroot, clear, cp, cpio, cut, date, dd, df, du, echo, ed, egrep, env, false,
fgrep, find, grep, gunzip, gzip, halt, head, hostid, hostname, hush, id, init, kill, less, ls, md5sum, mkdir, mknod, mount, mv, nc, nslookup,
poweroff, printf, ps, pwd, reboot, rm, sed, sh, sleep, sort, tar, tee, telnet, test, touch, tr, true, tty, umount, uname, unzip, vi, wc, whoami,
xargs, yes, zcat

Drawing CPU part of boot chart

I'm using kstat for drawing CPU part of boot chart (see my previous posts). I need cpu values for "user","nice","system","idle","iowait" in such order (sample output):
cpu 8 0 141 313 230 0 0 

I've written the small kstat utility and added its call in a bootchartd script (utility writes /var/log/bootchart/proc_stat.log):
#include <kstat.h>
#include <sys/sysinfo.h>
#include <stdio.h>
#include <string.h>

static kstat_ctl_t *kc;
static kstat_t *ksp;

static unsigned int cpu_user, cpu_system, cpu_nice, cpu_idle, cpu_iowait;

int main(int argc, char **argv) {
cpu_stat_t *cpu_stat;

kc = kstat_open();

if (kc != NULL) {

ksp = kstat_lookup(kc, "cpu_stat", 0, "cpu_stat0");
if (ksp != NULL && ksp->ks_type == KSTAT_TYPE_RAW)
{
if (kstat_read(kc, ksp, NULL) != -1 &&  
ksp->ks_data_size == sizeof(cpu_stat_t))
{
  cpu_stat = (cpu_stat_t *)ksp->ks_data;
  cpu_user=cpu_stat->cpu_sysinfo.cpu[CPU_USER];
  cpu_nice=cpu_stat->cpu_sysinfo.cpu[CPU_WAIT];
  cpu_system = cpu_stat->cpu_sysinfo.cpu[CPU_KERNEL] ;
  cpu_iowait=cpu_stat->cpu_syswait.iowait;
  cpu_idle=cpu_stat->cpu_sysinfo.cpu[CPU_IDLE];

 printf("cpu  %d %d %d %d %d 0 0\n",
 cpu_user,cpu_nice,cpu_system,cpu_idle,cpu_iowait);
        }
    }
  }
}

Reducing Boot Time

In the last MilaX release (0.3.3) I've tried to reduce boot time from kernel startup to desktop environment up and running. I left only necessary SMF-services for LiveCD and changed startup sequence. The main idea - network services and compressed usr filesystem mounting can start after X server starting.
Here the services list after full booting:
STATE          STIME    FMRI
online         19:49:10 svc:/system/svc/restarter:default
online         19:49:13 svc:/network/datalink-management:default

Bootchart picture offers some details:





Certainly USB-booting yields the best results: for example on my DELL notebook I've booted MilaX from usb stick for 27 seconds. I've not included Moinak's code for compressed ramdisk support in this release, but I hope that I'll make it further.

Getting maximum info at booting

As I already written above, it's very useful to know all the current processes in boot time. You can get more interesting information. If we look at the contents of "live-devices-local" script in OpenSolaris LiveCD we'll see possibility to use iosnoop with output in logfile (iosnoop uses DTrace to monitor disk events in real time):

...
# Turn on I/O tracing if requested and possible
trace=`prtconf -v /devices|sed -n '/trace/{;n;p;}'|cut -f 2 -d\'`
if [ "$trace" = "on" ]; then
if [ -n "$mntpt" ]; then
outputfile="${mntpt}/traceout"
echo "Enabling I/O Tracing ..." > /dev/console
/opt/DTT/Bin/iosnoop -Deg > "$outputfile" 2> /dev/console &
# Wait for iosnoop to actually initialize
sleep 10
else
echo "Unable to enable I/O Tracing" > /dev/console
echo "Must have a mountable Solaris root slice on harddisk" > /dev/console
echo "to hold trace output" > /dev/console
fi
fi
...

Here's another fast way without using "live-devices-local" script: boot with "-m milestone=none" and next (I'm using opensnoop):

mount -F tmpfs -o size=32m swap /var/log
/opt/DTT/Bin/opensnoop -eg > /var/log/opensnoop.log &
svcadm milestone all

Except iosnoop a lot of helpful information can be gathered using other DTrace scripts (opensnoop,errinfo) with various arguments. For example, the opensnoop script considerably simplifies search of all files necessary for booting without errors.

Boot chart with help of DTrace and Python

Anonymous tracing allows to receive more interesting information about Solaris booting process. I use a simple D-script (boot.d):

#!/usr/sbin/dtrace -Cs
#pragma D option quiet
/* I need process pid, his forks and life time */
proc:::create
{
printf("<fork ppid=%d cpid=%d execname=%s time=%d />\n",
pid,args[0]->pr_pid,execname,`lbolt*10/ `hz);
}

proc:::exec-success
{
printf("<process pid=%d execname=%s time=%d />\n",
pid,execname,`lbolt*10/ `hz);
}

proc:::exit
{

printf("<end pid=%d execname=%s time=%d />\n",
pid, execname,`lbolt*10/ `hz);
}

Then I enable anonymous tracing:

dtrace -AFs /boot/boot.d
reboot

After reboot I write a logfile and disable anonymous tracing:

dtrace -ae -o bootlog
dtrace -A

Logfile looks like this:

CPU FUNCTION
0 | exec_common:exec-success <process pid=1 execname=init time=63 />
0 | cfork:create <fork ppid=1 cpid=4 execname=init time=66 />
0 | exec_common:exec-success <process pid=4 execname=ksh93 time=67 />
0 | exec_common:exec-success <process pid=4 execname=autopush time=87 />
0 | proc_exit:exit <end pid=4 execname=autopush time=92 />
0 | cfork:create <fork ppid=1 cpid=5 execname=init time=92 />
0 | exec_common:exec-success <process pid=5 execname=ksh93 time=92 />
0 | exec_common:exec-success <process pid=5 execname=soconfig time=94 />
...

Now by help of a python it's possible to parse logfile. I've written a small script bootchart.py for parsing and chart construction. It would be great to trace and draw the cpu part but this is not implemented yet.
To create boot chart you need run bootchart.py with logfile as an argument:

bootchart.py bootlog

This is a boot chart example for OpenSolaris 2008.11:
