lx64 brand (current status)

Hi,
I progress rather slow in recent weeks, and will still be in the hard process of checking Linux system call emulation and adding new ones for quite a (unpredictable) time.
However, we can now run some "real" Linux programs now. No singal, no thread, no trace ...
Regards,
Wei Shen

That sounds like fantastic progress.
Could you share a little more about what you've done, and how you're making
forward progress? I'm guessing that you start by booting a 32-bit Linux
zone, and then run individual 64-bit applications within that. Is that
right, or do you have a zone that just runs 64-bit binaries?
Have you thought about making this an official Project on opensolaris.org?
We've seen a fair bit of interest in 64-bit Linux on this list in the past,
so there might be other people who would be eager to help out. You don't
need a formal project for that, but it might make collaboration easier.
Nils

awesome...
i'd also wonder if getting a project, or at least a source code
repository, up onto opensolaris would be helpful. if you've actually got
full 64-bit zone with processes up and running, then it sounds like analyzing
and fixing individual system calls could be a parallelizable task that other
community members might be able to help out with.

Dear Edward,
awesome...

That is great if possible. I already feel overwhelmed by the task. However, I think it still requires some time to make a relatively steady 64-bit zone. I have done only some simplest test yet. And I also need time to trim my code to make them neat enough to appear in public ^_^
How about the progress on "Bug 6562537"? Please inform me when it get fixed, so that I can update my code accordingly.
Regards,
Wei

hey wei,
i putback the fix for 6562537 on monday, so you should be able to get
it now. :)
i also had two more questions:
- what distro are you working with? (centos 3.x?)
- have you gotten to the point of actually trying to boot a full
64-bit version of that distro? or are you still booting a 32-bit
version and just running 64-bit applications by hand?
it's great to hear about your progess.
thanks
ed

I see. Thanks!
i also had two more questions:
- what distro are you working with? (centos 3.x?)
Centos 3.8
- have you gotten to the point of actually trying to boot a full
64-bit version of that distro? or are you still booting a 32-bit
version and just running 64-bit applications by hand?
No, I use a 32-bit distro as the test environment. But, I think the only difference between booting a "full 64-bit distro" and a 32-bit distro is that we are not running 64-bit init, login, bash, and several basic daemons. I have not tried, but I think I can not make all of them run presently. In fact, I found several weird problems today.

No, it indeed needs not so much time, but I have to pause time to time for other work.
Could you share a little more about what you've done, and how you're making

zone, and then run individual 64-bit applications within that. Is that

Yes, I start by adding 64-bit support (elfexec, syscall callback, 64bit support library, etc.) to a lx zone, and my plan is finally one lx brand for both 32-bit and 64-bit Linux.
Have you thought about making this an official Project on
opensolaris.org ?
We've seen a fair bit of interest in 64-bit Linux on this list in the past,
so there might be other people who would be eager to help out. You don't

That sounds great! On my side, the only problem is that I progress slow and may be unable to be faster, for other work I have and also for lack of a convenient x64 development platform.

Wei Shen
