Хphoton Port for QNX 6.4.1

[bbceler]

André Wösten выложил на http://qnx.falloutshelter.de/ сорсы xphoton.
Он строится на xorg-server-1.6.3.
Там тоже вы найдете phinstaller.

Посмотрел, но в деле не пробовал. Интересно. Сам XPhotonом пробовал заниматься, но заморочек в нем много оказалось. Инструкцию по установке, правда, маловата.

Sorry, I cannot speak russian (but Google Translator did the job for me). You can find more information for installing it here:

http://209.226.137.8/sf/discussion/do/listPosts/projects.pkgsrc/discussion.pkginfo.topc12895

I posted it on openqnx and foundry27 too, but apparently noone is interested. I hope you can do something with it. For questions just write here, I will check this thread from time to time.

Best regards,
André Wösten

I compiled Xphoton without problems.
And so:

but
843329575   1 ./Xphoton           10r READY

I have the return to the state "./Xphoton 10r SIGWAITINFO"  in the case of the old version Xphoton.
This same is when I change the size of the window.
New xphoton still stays in the READY state after change the size when old xphoton   go to SIGWAITINFO

Okay, thank you. I will test it myself and give it a try!

OK, I found the problem. I used an internal signalling pipe (by using file descriptors) to trigger the dispatcher of the DIX. But I didn't empty it after using it.

Thanks for giving me this hint. I always wondered why the Xphoton server needs so much CPU power (in the system monitor of QNX). Now I found out that he hanged in a loop between blocking/waking up in the server scheduler which was caused by that event pipe. If you want to fix it, do following:

1. Remove the mieqProcessInputEvents-call from the RootlessWakeupHandler in miext/rootless/rootlessScreen.c

2. Replace the ProcessInputEvents function in hw/xphoton/ntoEvents.c by this one:

Код:

void
ProcessInputEvents(void)
{
int x = 1;
char byte;

mieqProcessInputEvents();
   
// Empty the signaling pipe
while (x == 1) {
x = read(ntoEventReadFD, &byte, 1);
}
}

Thanks again!

Now change the size of the window and movig window work but STATE Xphoton is RUNNING, REPLY and  READY
After closing xlogo state Xphoton changes still. And CPU work very hard.
And why state Xphoton does not change to SIGWAITINFO how this does old version Xphoton?

[awoesten]

Bogdan,

back to life. Now I really solved this problem. This is the correct code to clean the signalling pipe:

Код:

void
ProcessInputEvents(void)
{
xEvent  xe;
int x = sizeof(xe);
   
    mieqProcessInputEvents();

    // Empty the signaling pipe
    while (x == sizeof(xe)) {
      x = read(ntoEventReadFD, &xe, sizeof(xe));
    }
   
}

RootlessWakeupHandler in miext/rootless/rootlessScreen.c has to be disabled still. Now I get SIGWAITINFO

Still working on the Xphoton port, implemented correct moving of windows, correct displaying  of more than 1 window and some other stuff. Now I have to correct some disgusting charset and keyboard handling stuff.

I will report further progress here.

Regards
André

André,
OK, I checked now it is much better.
For the Xphoton compilation I prepared the pkgsrc package using your patch.

bogdan.
