[kaffe] now what?
Hi folks Well, my kaffe port to the Helio pda (mipsel, r3912 cpu) has hit a stumbling block and I'm a little stumped. When trying to execute a class file, findInJar.c (I think) does a readdir() on some directory. readdir() is crashing with a signal 10. I can't figure out why ;-( I've tried multiple versions of glibc. No one on the linux-mips list can duplicate the problem. I wonder if it has something to do with my file system being read only? Anyway, here are the options I could come up with: 1. Contact the glibc developers and ask them some specific questions. Unfortunately, the most appropriate mechanism they have (per their website) is their bug tracker. If at all possible, I'd like to talk to someone with knowledge of glibc. Does anyone know how to get ahold of those guys? 2. Scrap glibc for uClibc. Will kaffe compile/run with uClibc? 3. Figure out how Pocketlinux did this. Can someone tell me how to get to the Pocketlinux source out of CVS? 4. Hack kaffe. I really don't want to do this. 5. Scrap kaffe. Don't worry, after this many years option number 4 is much much more appealing. Does anyone have any other ideas?

[kaffe] kaffe debug output
Hi folks A few days ago I sent the output of running kaffe with -vmdebug ALL to the list. Dalibor wondered why calls to initCollector() were missing and suggested I use the CVS snapshot. Below is the output from -vmdebug ALL with CVS code from 01/02/04. initCollector() calls are present. Why is it trying to add Klasses.jar to the classpath? Wasn't it replaced by rt.jar? Also, the 2nd to last line mentions freelist 0. Is this ok? Does it makes sense to double check the alloc'd/free'd amounts of memory?

Re: [kaffe] SIGSEGV running kaffe
Dalibor Happy New Year! I've got to research how to start gdbserver after boot with no command prompt. Any suggestions? Have you tried asking on the gdb mailing list? No. I asked on the linux-mips list. After I wrote this I began to suspect the problem was the automatic console busybox starts up on the serial port. The linux-mips folks confirmed this and I've got to try to turn off the busybox serial console . Could you retry with kaffe from current CVS? The lack of initCollector() for one in your output strikes me as very weird. That's one of the first things to happen when kaffe is initialised, see baseClasses.c for details. Will do.

Re: [kaffe] SIGSEGV running kaffe
Kevin, et al Are you trying to use the JIT? So far as I know, the JIT3 engine is still broken for MIPS/mipsel, and generates code which ends up dereferencing uninitialized pointers embedded in internal data structures. No. I configured kaffe using --with-engine=intrp Mark _ Tired of slow downloads?

[kaffe] SIGSEGV running kaffe
Hi folks A little update on my tracking down the cause of the SIGSEGV when kaffe tries to run a class on my mipsel-linux pda. I've temporarily ruled out using gdbserver. I've only got 1 serial port and its running a shell. I've got to research how to start gdbserver after boot with no command prompt. Any suggestions? In the meantime, I ran: /bin # kaffe-bin -ss 1M -ms 1M -mx 2M -as 1M -cp /bin -vmdebug ALL FirstClass and got the output below. Any suggestions about what I'm looking for? A cursory glance at the alloc/malloc information doesn't make the problem jump out at me. I was hoping it would be as simple as trying to malloc something at 0xf or some other such screwy address.

Probably quite slow, if it works at all. You need a kernel that's compiled with kgdb support. Do you mean track back to kaffe from where the kernel generates the SIGSEGV? b) Adding support for gdb stubs for mips to kaffe. There is a mips-stub.c in the linux kernel sources [1] and there is some documentation on using remote stubs [2]. We are thinking alike ;-) This is the next step in my plan. Over the weekend, I dug out mips-stub.c (ok, in my kernel source its called gdb-stub.c). I've been researching what gdb required stuff is present, is missing and so on. Do any of the kaffe mips users have mipsel appropriate debugging stubs lying around. that I can look at? I can't believe I'm the first guy to do this.

[kaffe] mipsel SIGSEGV
Hello A few weeks ago I wrote about the SIGSEGV when executing a class with Kaffe built for mipsel. I've tried cross debugging with gdb (from i386 connecting to mipsel) with little success. The latest problem is: (gdb) target mips /dev/ttyUSB0 Expected "", got "": FAIL Expected "", got "": FAIL Expected "", got "": FAIL Failed to initialize. Ending remote MIPS debugging. You can't do that without a process to debug. Is anyone familiar enough with gdb to tell me what's missing? I know kaffe should probably be compiled with the appropriate gdb -stubs.h & .c files; but I don't understand what's going wrong with the initialization.

Its late on Sunday and I wanted to post it before I signed off and forgot. I'll do some analysis on it tomorrow. On a related subject, I need advice about debugging kaffe remotely. I'd like to run gdb on my i386 laptop, run kaffe on my mipsel pda and debug mipsel kaffe from my laptop. Can anyone point me to READMEs, FAQs or HOWTOs on the web?

[kaffe] good initial stack/heap size in embedded environment
Hi folks I've gotten kaffe compiled and installed on my Helio. I'm getting a SIGSEGV when I try to use kaffe to execute a class file. I've tracked it down to kaffe/kaffevm/itypes.c It happens among the calls to initPrimClass in initTypes(). I don't get the signal in the same place-each time I run a different number of initPrimClass calls succeed. It got me wondering if kaffe is trying to reserve too much stack or heap. The Helio has 8Mb RAM and 2Mb flash. Can I use the default stack/heap size (what is the default size?) or should I specify one at the command line? If I've got to feed sizes in at the command line, what are reasonable values? Mark _ Say goodbye to busy signals and slow downloads with a high-speed Internet connection!

[kaffe] cannot find libnative
Hi folks For the last couple of years I've been trying to create a version of kaffe for use on my mipsel based Helio pda. It been an on again, off again project. Well, its on again. I've taken three paths. The first is working with a copy of the Transvirtual pocketlinux kaffe source I found buried on some ftp site on the net a few months ago. The second path is trying to use the v1.1.0 release of kaffe. The third is using a prebuilt version I got from Transvirtual's pocketlinux website several years ago. What started as an attempt to create a java PIM for myself has turned into "I'd really like to be able to create my own mipsel version of kaffe." I'll use the prebuilt version only when I get tired of hacking the kaffe source. I haven't gotten tired of it yet. Anyway, as of today, the status is: 1. The Transvirtual pocketlinux kaffe source will compile for mipsel and I can include/exclude the features I want. It also has the Transvirtual framebuffer awt implementation. However, it won't run. I've tracked the problem to a call to kaffevm/systems/unix-jthreads/internal.c A call to readdir(DIR* dir) crashes with a signal 11 and I can't figure out why. 2. The kaffe v1.1.0 release also compiles for mipsel. I can also include/exclude the features I want. When it runs, it complains about not being able to find libnative. Based on a quick read of the mailing list archive and a look at the generated code, it looks like (even when compiled statically) there are a series of libraries kaffe needs at run time. The libnative.a in question is about 2mb. The pda won't hold that much. So I've got 2 choices. Continue to work with the Transvirtual source, solve the readdir problem and any others that come up. Or, use kaffe v1.1.0 and figure out how to compile the required libraries into the kaffe executable. Then merge the Transvirtual framebuffer awt code into kaffe v1.1.0 or v1.2.0 or whichever version y'all want. I think option 2 is the way to go. kaffe v1.x is actively developed and supported. Can someone tell me if there is a way merge the libraries kaffe needs at run time into the static binary? Can anyone give me any hints as to merging in a new awt implementation?

[kaffe] Sun's javac and compiling rt.jar without debugging symbols

Pocketlinux' Kaffe was and still is one of the most complete and best embedded solutions. For that reason I'd like to see Kaffe.org's version try to reach its full potential in this avenue. Pocketlinux Kaffe is still, AFAIK, the only Java virtual machine for the Helio with its little endian mips processor. I'm going to go out on a limb and say its the only one for the mips architecture.
