[coLinux-users] hang on xp

[Paolo M. <pao...@gm...>]

Hi Henry

today for the first time I try your RC4 under XP.
I have modified the console size X and Y.

I have do it several times, so I think to do it in a correct way.

This time I have change a little my patch.
I have added two #define in include/linux/cooperative.h
#define CONSOLE_SIZE_X 120
#define CONSOLE_SIZE_Y 60

and all (kernel cocon.c, daemons and ntdriver) use
#include <linux/cooperative.h>

and use CONSOLE_SIZE_X and CONSOLE_SIZE_Y.

These are my changes :

build/linux-2.6.22.18-source/drivers/video/console/cocon.c:	c->vc_cols
= CONSOLE_SIZE_X; // 80; BY PAOLO
build/linux-2.6.22.18-source/drivers/video/console/cocon.c:	c->vc_rows
= CONSOLE_SIZE_Y; // 25; BY PAOLO
build/linux-2.6.22.18-source/include/linux/cooperative.h:#define
CONSOLE_SIZE_X 120  // BY PAOLO
build/linux-2.6.22.18-source/include/linux/cooperative.h:#define
CONSOLE_SIZE_Y 60   // BY PAOLO
stable-colinux-20080512/src/colinux/kernel/monitor.c:#include
<linux/cooperative.h> // BY PAOLO
stable-colinux-20080512/src/colinux/kernel/monitor.c:	rc =
co_console_create(CONSOLE_SIZE_X, CONSOLE_SIZE_Y, 0, &cmon->console);
// 80,25 BY PAOLO
stable-colinux-20080512/src/colinux/os/winnt/user/console-nt/widget.cpp:#include
<linux/cooperative.h> // BY PAOLO
stable-colinux-20080512/src/colinux/os/winnt/user/console-nt/widget.cpp:
       r.bottom = fs.Y * CONSOLE_SIZE_Y;  // 25 BY PAOLO
stable-colinux-20080512/src/colinux/os/winnt/user/console-nt/widget.cpp:
       r.right = fs.X * CONSOLE_SIZE_X;   // 80 BY PAOLO
stable-colinux-20080512/src/colinux/os/winnt/user/console-nt/widget.cpp:	size.X
= CONSOLE_SIZE_X; // 80 BY PAOLO
stable-colinux-20080512/src/colinux/os/winnt/user/console-nt/widget.cpp:
       size.Y = CONSOLE_SIZE_Y; // 25 BY PAOLO
stable-colinux-20080512/src/colinux/os/winnt/user/console-nt/widget.cpp:
       region.Right = CONSOLE_SIZE_X-1;  // 79 BY PAOLO
stable-colinux-20080512/src/colinux/os/winnt/user/console-nt/widget.cpp:
       region.Bottom = CONSOLE_SIZE_Y-1; // 24 BY PAOLO

As you can see I have inserted a comment "BY PAOLO" at every change.

All is compiled OK (under vmware, slackware 11.0).

After that I use the old colinux-daemon --remove-driver to remove the driver.
Then I have installed the new package and install the new driver with
the new colinux-daemon --install-driver
I have removed and installed the ntdriver WITHOUT rebooting.

I have worked for some hours, than I have tried to compile qemu under colinux.
After a while I have had internal  OOP, like when under a real linux
system I make an error coding a module.
I saw several line and at the end of them a line with <cocon> and an address.
I have thought I made an error in patching the size of console, so I
didn't take note about the fault.
I could using other windows opened, but I could not close the console-nt window.
I could not close windowXP in a clean way.
Using task manager I had the colinux-daemon at 99% of the CPU.

Now I have checked my changes and I think all was OK.

Before trying the RC4 I used the original 0.7.2 with the endless
patch. My console was 100 x 50. (not 120 x 60, like the new one).

A question :
***************
Is it secure remove the ntdriver and install a new ntdriver without rebooting ?
Under linux it is possibile and it is secure, under XP I don't know.

Now I have recompiled all (with my patch) and it is working OK. I have
recompiled qemu under colinux and all is OK.

I underline that I have used
> make clean colinux kernel
to rebuild my version, because there is a little bug in colinux
buildind process.
Using make clean I am sure the building is OK.

I realize that it is difficult trace an error with this information.
But I have decided to post the error.

Paolo
