[kaffe] Calendar performances
Hi all, I'm using a call to rightNow = Calendar.getInstance(); and the first call need 44 seconds to accomplish (kaffe 1.1.6 - MIPS 400MHz machine) the following calls are fast (less than 1 second, I did not measure them) Is there some reason for this - is there some initialization - can it be avoided (I just need system date and time). thanks giammy -- Gianluca Moro http://groups.yahoo.com/group/embeddeditalia/ ISCRIVITI alla Mailing List Italiana su LINUX EMBEDDED [EMAIL PROTECTED] Visit http://ilpinguino.altervista.org/ ___ Yahoo!

However it is possible to disengage the heuristic by removing the property EXTERNAL_DECO in libraries/clib/awt/X/tlk.c:tlkProperties(). Could you try this ? sorry for the delay: I just take up the kaffe work again :-) I tested the modification with no results :-( the window is some (8/9) pixel more shifted to the bottom ... thanks giammy -- Gianluca Moro http://groups.yahoo.com/group/embeddeditalia/ ISCRIVITI alla Mailing List Italiana su LINUX EMBEDDED [EMAIL PROTECTED] Visit http://ilpinguino.altervista.org/ ___ Yahoo!

[kaffe] split function (String): slow implementation
Hi all,
I tested the following program, where I use
the split functin.
the 1st call to split needs 7/8 seconds to be accomplished, while
all the following calls are quickly done.
(kaffe-1.1.6 compiles on a MIPS platgorm - AMD au1100, 400MHz)
It seems that kaffe need to to something (parser initialization?)
very time consuming: is it a normal behaviour, or should not
happen this?
thanks

[kaffe] initial frame position
hi all,
I'm running kagge with a graphical output
directly on X, without any window manager.
I see that all the applicatio I start are placed in (0,0)
(upper lefr corner of the screen) while starting
my java application under kaffe it is placed in a bit
on the left, and below the upper screen (about (5,30)).
I imagine this is some default setted in kaffe or in the
java interface: is there an option to force
the position in (0,0), osmething analogous to
give -geometry +0+0?
(My test:
#
LD_PRELOAD=/usr/X11R6/lib/libX11.so:/usr/lib/libpng.so:/usr/lib/libz.so:/usr/local/lib/libjpeg.so
/usr/local/kaffe/bin/kaffe -geometry +0+0 -Dkaffe.awt.nativelib=xawt
-Xbootclasspath/p:/usr/local/kaffe/kaffeawt.jar Jnoti
gives:

[kaffe] paint and repaint ...
sorry for the probably dumb question: I have a small example that draws a rect in a paint method of the canvas. based on an event I redraw the rect with a different color (with a call to fillRect). Then i call repaint with the including modified area to avoid flickering while updating. The update is correct with java from j2sdk1.4.2_06, while in kaffe 1.1.6 with Tiny-X on a MIPS machine, the windows is cleared and only the modified rectangle is drawn: seems that repaint clear all the window and repaint only the requested rectangle: should not it clear only the requested rectangle? thanks giammy -- Gianluca Moro http://groups.yahoo.com/group/embeddeditalia/ ISCRIVITI alla Mailing List Italiana su LINUX EMBEDDED [EMAIL PROTECTED] Visit http://ilpinguino.altervista.org/ ___ Yahoo!

Do I need to enable some flags when running the demo?

[kaffe] scaled image efficiency
Hi all, I'm testing Kaffe 1.1.6 on a MIPS processor (AU1100, 400MHz) and I noted the image refresh is very slow: 10-20 seconds to draw the image whenever I move another window over it! I traced the code, and I see that the time is wasted in initScaledImage function in file libraries/clib/awt/X/img.c, fundamentally in the rescaling code. (if I draw the image without scaling it the timing is very good) Anyone found such a problem? is it correct that initScaleImage is called whenever the image comes to foreground? is there a way to optimize the scaling, or not to call initScaleImage so frequently? The 10-20 seconds pause is not acceptable in the final program :-( thanks giammy -- Gianluca Moro http://groups.yahoo.com/group/embeddeditalia/ ISCRIVITI alla Mailing List Italiana su LINUX EMBEDDED [EMAIL PROTECTED] Visit http://ilpinguino.altervista.org/ ___ Yahoo!

Re: [kaffe] Native library libnull.so
The idea is to check a proprty that tells Kaffe which native library to load for the native implementation of the AWT code. In your case, I guess, you'd need to add -Dkaffe.awt.nativelib=xawt (assuming that's what you compiled against) to your command line invocation. You should also get the same result by just using kaffe -Xkaffe-xlib-awt HelloWorld Thank you very much: I got it The problem was tht the xawt library was not compiled as in the libraries/clib/awt/Makefile the line #MAYBE_KAFFE_X_AWT = X was commented (I thought that, with the --with-x option in the configure I should have it compiled) Anyway I uncommented and made make again. The -D option get the correct library (while if I use the -Xkaffe-xlib-awt options I get an Error: Unrecognized JVM specific option `-Xkaffe-xlib-awt'. Now kaffe starts correctly (I have another problem, I descrive in the next mail :-( thanks again giammy -- Gianluca Moro http://groups.yahoo.com/group/embeddeditalia/ ISCRIVITI alla Mailing List Italiana su LINUX EMBEDDED [EMAIL PROTECTED] Visit http://ilpinguino.altervista.org/ ___ Yahoo!

Hi all,

My current problem is a helloworld program with

do not keep the id of the various frame, or do not update it
or something so ...
(the code on Kaffe on PC works OK)
Anyone already found something similar?
Looking around in the code, I noted in file

Java_java_awt_Toolkit_graInitGraphics
the following code
if ( graphicsP == NULL ) {
graphicsP = (TLKGraphics*) TLK_MALLOC( sizeof(TLKGraphics));
graphicsP-gc = GrNewGC();
graphicsP-region = 0;
graphicsP-target = (GR_ID)target;
graphicsP-targetType = targetType;
graphicsP-gid = (TLK_GRAPHICS_ID)graphicsP;
graphicsP-magicNo = TLK_GRAPHICS_MAGIC_NO;

which do not update target if graphicsP is already initialized
I think the code should be
if ( graphicsP == NULL ) {
graphicsP = (TLKGraphics*) TLK_MALLOC( sizeof(TLKGraphics));
graphicsP-gc = GrNewGC();
graphicsP-region = 0;
graphicsP-gid = (TLK_GRAPHICS_ID)graphicsP;
graphicsP-magicNo = TLK_GRAPHICS_MAGIC_NO;
}
graphicsP-target = (GR_ID)target;
graphicsP-targetType = targetType;
where target is always initialized (this draw all the windows)
Now the problem is that a background windows is not refreshed :-(

[kaffe] kaffe and AWT on MIPS with multiple windows
Hi all,
I'm working on the porting of KAFFE on MIPS platform, with
AWT and Nano-X interface.
My current problem is a helloworld program with
multiple frames: the problem is that all the drawing
is done on the first created frame: it seems thar AWT
do not keep the id of the various frame, or do not update it
or something so ...
(the code on Kaffe on PC works OK)
Anyone already found something similar?
thanks
giammy
Here the example code
import java.awt.*;
import java.awt.event.*;
public class HelloWorld extends Frame {
String str;
public HelloWorld (String s) {
str = s;
}
public static void main(String[] args) throws Exception {
final Frame frame = new HelloWorld(Hello1);
final Frame frame2 = new HelloWorld(Hello2);
final Frame frame3 = new HelloWorld(Hello3);
frame.setSize(400, 200);
frame2.setBounds(400, 200, 400,200);
frame3.setBounds(200, 400, 400,200);
frame.setTitle(1);
frame2.setTitle(2);
frame3.setTitle(3);
frame.setVisible(true);
frame2.setVisible(true);
frame3.setVisible(true);
}
public void paint(Graphics g) {
System.out.println(demo: paint + this);
g.drawLine(10,10,200,200);
g.setFont(new Font(Dialog, Font.PLAIN, 50));
g.setColor(Color.red);
//g.setBackground(Color.red);
g.drawString(str, 10, 100);
}
}

[kaffe] kaffe + nano-X + MIPS
Hi all, As you (probably) remmember I'm porting kaffe on a MIPS platform with Nano-X. PROBLEM 1: I was stunned as the java windows frame was shown, but the contents were missing. The problem, as pinted out Dalibor, was caused by the parameter passing on MIPS platform. I compiled the libffi library and compiled kaffe with --with-libffi and the problem was solved. PROBLEM 2: I draw lines, rectangles, but not arcs!!! The problem was with the differents meaning in the GrArcAngle and java drawArc function: the conclusion was that, in file libraries/clib/awt/nano-X/graphics.c I replaced all occurences of GrArcAngle with GMY_GrArcAngle, and added the following define: #define GMY_GrArcAngle(id,gc,x,y,rx,ry,a1,a2,t) GrArcAngle(id,gc,(x)+(rx)/2,(y)+(ry)/2,(rx)/2,(ry)/2,a1,(a1)+(a2),t) Nano-X x,y is the center of the arc, while java x,y is the upper left point of the rectangle including the elipse containing the arc (desumed running vaious examples on PC) hope this helps, Now I ocntinue with the tests giammy -- Gianluca Moro Visit http://ilpinguino.altervista.org/ [EMAIL PROTECTED] MyBlog http://blog.libero.it/giangiammy/ __ Yahoo!

Re: [kaffe] kaffe awt and thread management on MIPS
Recently, I am working on JIT and XScale series, and I have commited some Nano-X related fixes into cvs repository. Could you please take it a try with cvs head? However, thank you for sending and sharing the previous information about Nano-X AWT backend and threading on MIPS, which is another great platform Kaffe should support. Hi Jim, I found some problems with the last version of Kaffe (1.1.6), in particular, the problem I found was: java.lang.ExceptionInInitializerError caused by: java.lang.NullPointerException at java.awt.Toolkit.fntInitFont (Toolkit.java:native) Looking at the code, it seems that the function which initializa the fonts return an id (an integer, i think) while the nativeData field is declared as Pointer. I think that this gives the exception. I checked kaffe-1.1.5 and I saw tha nativeData was declared as Ptr: compiling kaffe-1.1.5 and following the same steps I followed for 1.1.6, I got a runnable kaffe which gave no exceptions. I'll check, as soon as I get a working kaffe, the CVS head, but I think I'll need to change the Pointer declaration to test it :-( Anyway, thans so far for kaffe team support bye giammy -- Gianluca Moro Visit http://ilpinguino.altervista.org/ [EMAIL PROTECTED] MyBlog http://blog.libero.it/giangiammy/ __ Yahoo!

[kaffe] kaffe awt and thread management
I'm testing kaffe in MIPS platform with Nano-X: my test program open a windows, but do not show anything in it (while the same program on Pc show the inner objects) Tracing the code, I see that the function kaffe-1.1.5/libraries/javalib/java/lang/VMThread.java:sleep() is calling the function vt.wait with parameter 250ms, but it never returns. From what I understand, that function calls /kaffe-1.1.5/libraries/clib/native/Object.c:java_lang_VMObject_wait, whose debugging message gives me 0x10276010 (0x102622f8) waiting for 0x102622f8, 0 It seems that here the parameter (250ms) became 0: do I understand correctly? And if so, why (and where) the 250 value was lost?

Re: [kaffe] kaffe awt and thread management on MIPS
Hi, I compiled my kaffe on mips with the following ./configure --with-jikes=no --with-engine=intrp --enable-pure-java-math --without-esd --without-kaffe-x-awt --with-kaffe-nanox-awt --with-rt-jar=/home/AMDgiammy/kaffe-1.1.5/libraries/javalib/rt.jar --without-classpath-gtk-awt --enable-debug --with-nanox-include=/usr/include/microwin --with-nanox-library=/usr/lib --with-threads=unix-jthreads perhaps the problem on threads in the MIPS porting can be solved with ad appropriate configuration of ./configure or CFLAGS or so: I found in the web, for example setenv CFLAGS -G 0 -mno-abicalls -fno-pic -mcpu=r4300 -mips2 but such a configuration fails in the configuration, while finding the size of a void *. Is there someone who compiled a more recent version of kaffe (I'm working on 1.1.5), and have a working configuration?

That might suggest there is a bug in the config/mips/* implementation of the ABI, or in the JNI code. You can try bulding Kaffe with libffi, which comes from gcc, and is in general up to date with different ABI changes. If it's a bug in the JNI code, you could look at fixing the compiler warnings in kaffe/kaffevm/jni* directory. cheers, dalibor topic -- Gianluca Moro Visit http://ilpinguino.altervista.org/ [EMAIL PROTECTED] MyBlog http://blog.libero.it/giangiammy/ __ Yahoo!

I'm getting a very weird behaviour: if I start a demo
(just open a window and set a green background) it starts
with no errors, and stay there: 1 time in (about) 30

not see nothing!!!
...
that sounds like a race condition somewhere :( You may want to check
what happens during a successful startup vs a fialing startup and try
to
add 'synchronized' keyword in the class library for awt backend for
nanox where it turns out be appropriate :(
Hi Dalibor, I think the problem is in the thread library:
kaffe was compiled with standard thread library (pthread);
I tried to compile with the jthread library (--with-unix-jthreads)
and the initialization always complete correctly.
By the way, with pthreads, when the initialization was correct needed
30seconds, now it needs 10 seconds.
Now I'm testing programs behaviour, starting from helloworld:
import java.awt.*;
public class Hello extends Frame {
public static void main(String argv[])
{
new Hello();
}
public Hello() {
super(Hello World!);
Label hello = new Label(Hello World);
// bring it under geometry control
add(Center, hello);
resize(500, 500);
// map the widgets
show();
}
}
this works correctly on PC, while on Nano-X do not display
the label in the window (the window appears, but is empty)
The window title string on the contrary is shown correctly.
Now I'm investigating about this :-(
Thanks so far
bye

[kaffe] Awt - missing paint invocation
Hi all,
I'm testing a simple program with kaffe-1.1.5:
it draws some lines, and on PC it works correctly:
on my porting on MIPS machine, it do not show
anything: from what I have seen, the function
paint is not called: does anyone have an idea
where to check to verify why the function paint
is not called? (even if I add a label it is not
shown: it seems that everything in the frame is
not shown!)
Follows my test code:

[kaffe] problem starting kaffe with Nano-X - AWT

Hi, I'm working on a AU1100, with MMU; from the datasheet: The Au1100 processor is a complete SOC based on the MIPS32 instruction set. Designed for maximum performance at very low power, the Au1100 runs up to 500 MHz. Power dissipation is less than 0.25 watt for the 400 MHz version. Highly integrated with onchip SDRAM, SRAM/Flash EPROM memory controllers, a LCD controller, 10/100 Ethernet Controller, USB Host and Device, UARTs (3), and GPIOs (up to 48,24 dedicated). The Au1100 processor runs a variety of operating systems, including Windows® CE.NET, Linux and VxWorks. Moreover, the integration of peripherals with the unique, high performance, MIPS-compatible core provides low system cost, small form factor, low system power requirement, simple designs at multiple performance points and thus, short design cycles. For the configuration it was not very direct: I compiled kaffe on PC # ./configure --with-engine=intrp --enable-pure-java-math --without-esd --without-kaffe-x-awt --with-kaffe-nanox-awt --without-classpath-gtk-awt then I changed /home/giammy/working/kaffe-1.1.6/libraries/javalib/Makefile uncommenting the line: #MAYBE_PEERLESS_KAFFE_AWT = awt-implementations and gave the make.
