[sstepd-list] sstepd 0.2.1 has been released!

[Takahiro Y. <tak...@mo...>]

Hello again.  I'm alive :-)

sstepd 0.2.1 is out of door.  This is the second release from the
stable branch.  Please pick your copy from the usual place and give it
a try.  It just works here, but Your Mileage May Vary (tm).

In fact, the 0.2.1 had already been released in 16.12.2004, but I've
just forgotten announcing it on the site and lists.  Please don't sue
me for missing X'mas present :-)

sstepd 0.2.1 fixes 2 bugs found in 0.2.0:

 - Incorrectly states it's not running as root or not.
 - gcc 3.4.x compilation breakage.

As usual, any feature breakage on the release is safe to regard as a
bug.  And panics and errors in normal configuration is almost always a
bug.  Please report them, preferably at
sst...@li....

(Formatting of announcement is quite different from the 0.2.0 release
time; This time is quite tidy, terse, and readable, isn't it?)

I hope you enjoy it.
Bye,

[sstepd-list] sstepd 0.2.0 has been released!

[Takahiro Y. <tak...@mo...>]

Hello,

After 6 monthes of silence, sstepd 0.2.0 is tagged and ready for download.
Please get it from usual place.

This release is our first stable *alpha* one.
So feel free and jump in :-)

Moderate rewrite has been done on this release.  Please feel free to report
problems if it happens to fail or panicks on you.


Release Highlights:

1. sysfs support.
==================

Finally, sysfs is supported.  That is, we're no longer only for 2.4 kernels! 
(Tested here with 2.6.3 and 2.4.20.)

./configure should detect the version of kernel you are running and correctly
determine which scheme to be used.  Should it fails or you're crossing, use 
the --{enable|disable}-sysfs option to override it.


2. Working global options.  
===========================

The global options in the configuration file is fully working.

The 'disable_on' lets you specify affinity masks.

And the 'update_interval' option lets you specify the frequency update
interval.  This is what the '-i' command line option was meant for; as it
still has the precedence, so check your boot script again!


3. Massive updates on documentations.
======================================

The man pages are no longer crap.  They should now be somewhat at least
useful.  The CONFIG-FILE in the distribution is to be deprecated.


4. Much lower frequency update interval.
=========================================

The default frequency update interval has been changed to 66ms (15 updates/s).
It was 3000ms in previous releases.  If the new one is too low for your
machine, tune it with the configuration file, or use the '-i' command line
option.


5. Hardened parser/lexers.
===========================

The error/token checks on parser/lexers are hardened.  Please help us hardening
them more further by providing crashing cases.


Bugs? Suggestions? 
Please feel free to speak your mind at <sst...@li...>.

We'll be glad to hear your feedback and ideas!

Enjoy,

[sstepd-list] sstepd 0.1.8 has been released.

[Takahiro Y. <tak...@mo...>]

Hello, 

sstepd 0.1.8 is ready.

This release contains the fix to a potential blocker in 0.1.7.
In fact, it seemed that 'autoheader' invoked spuriously on 'make install.'

The culprit turned out to be my autogen.sh.
That little thing is for deleting/regenerating auto* stuff, but it appearently
did in wrong order. I've fixed that, and hopefully did the right thing.
(For curious: use CVS.)

If that issue blocked your testing, please try 0.1.8.

Other release highlights:
- Other build system fixes/tidy-up.
- Man pages should be more readable.
- Man pages are now generated.
- Started documenting sstepd.conf(5).

... Almost everything are irrelevant to actual functioning.

As usual, any feature/build breakage is a bug.
Please report it on the sstepd-devel list.

Enjoy,

[sstepd-list] sstepd 0.1.7 has been released.

[Takahiro Y. <tak...@mo...>]

Hello,

sstepd 0.1.7 is out of door.
This release is to be alpha (not pre.)

Well, cpufreqd appears to be equipped with CPU monitoring since 1.1-rc1.
But sstepd has had a big step forward, too:

  Configuration file support has been added.

The parser / operation code is not heavily tested, though.
It will probably break if you feed something strange.
So please beware.

Other release highlight is:

  - The cputime load model now takes moving average.
     (interval option in the config file)

  - Following load models have been added:
    'loadavg_1', 'loadavg_5', 'loadavg_15' (measures load average)
  
  - Following power mode have been added:
    'const' (constant freq/rate),
    'linear' (linear scaler),
    'binary' (binary stepper),
    'powersave' ('powersave' governor),
    'performance' ('performance' governor).

  - Broken long option support has been fixed.
    --help and --version, has been restored.

Anyways, now we have configuration file support.
Now we need is a comprehensive documentation, and a handful of useful modules.

So please take a look of the new sstepd, code up (or just suggest) something cool, and contribute!
Let's make it more useful.

Enjoy,

[sstepd-list] sstepd 0.1.6 has been out!

[Takahiro Y. <tak...@mo...>]

Hello, 

Oops. I did it again. Another midnight release ;)

sstepd 0.1.6 has been released.

This is pre-alpha as usual; so please beware.

read_cpufreq_info() now restores current cpufreq governor. 
This makes SIGIO not to leave CPUs under userspace governor without control.

Next, termination mode has been defined. sstepd now switches CPUs into 
performance mode if it gets terminated in demand-based control mode. 
Nothing special will be done if it's in other modes.

So in short:
SIGUSR1, SIGTERM  -> Always terminate in powersave mode.
SIGUSR2, SIGTERM  -> Always terminate in performance mode.
(SIGHUP,) SIGTERM -> Switches CPUs into performance mode on termination. 
                     This is the new behavior.

Finally the '-f' (--foreground) switch makes sstepd to dump its output right onto
stderr.

Please report any feature/build/etc breakage on sstepd-list or sstepd-devel.

Enjoy,

[sstepd-list] sstepd 0.1.5 has been out!

[Takahiro Y. <tak...@mo...>]

Hello,

I'm not quite sure this reaches somebody's mailbox,
sstepd 0.1.5 is out today.

The '-i' (--interval) option has been added for tweaking CPU frequency update
interval. The smaller interval gives usually better response/performance.

The man page readability has been improved, I guess.
And the architecture reforming for implementing modules continues since 0.1.4.

If there's any feature breakage, please report it at sstepd-devel list.

Enjoy,
