[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.

Regards
Paolo

Have you replaced the file "vmlinux"? You should!

Yes, I saw  are all changes, I know. Think, you have changed correctly.

Yes, it's save, if you have verifyed, that the driver was unloaded.
Under Windows the driver sometimes can not unload, if any daemon is
active. So, I remember, you don't get an error. After --remove-driver
you should check, that the driver is true unloaded. Only if no driver is
installed, the next --install-driver is working.

You have cleaned the Linux kernel?

The source has no dependency to "include/linux/cooperative.h". You needs
to remove all objects (*.o) and archives (*.a), which can have the
console size compiled in.

Your patch needs to rebuild all. All means coLinux ntkernel (linux.sys),
daemons (colinux-console-nt) and the Linux kernel (vmlinux).

I suggest you to use these patches:
  console-size-40x120-colinux-0.7.3.patch
  console-size-40x120-linux-2.6.22.18-co-0.7.3.patch
There don't exist build time depency for console size between Linux
kernel and ntkernel. Only rebuild the coLinux driver and daemons ("make
clean && make colinux"), than reinstall the driver and use the new
daemons to have the new console size.
You not need to rebuild Linux kernel, after you have ones compiled with
the runtime size set (CO_OPERATION_CONSOLE_SIZES).

This patch for console sizes defines exist in 0.8.0 now, since yesterday
;-) Checkout the last source from SVN or from autobuild.

I have also uploaded console with 40x120 for 0.8.0:
http://www.henrynestler.com/colinux/testing/devel-0.8.0/20080520-con-40x120/

The same as 0.7.3:
http://www.henrynestler.com/colinux/testing/stable-0.7.3/20080521-con-40x120/

OK, my old driver was unloaded correctly because I could install the new driver.

No, I have not cleaned the Linux kernel.
I have only rebuild it using make in the linux-xxx-build directory
I thought that the linux building process automatically sees the
changes and recompiles the new source.
Maybe it was better to make clean and rebuild all the Linux kernel to
avoid dependecies problems.

Ok, is this done by make clean in the linux-xxx-build ? Is it right ?

OK, Now I check my changes to understand if I have made some error
(maybe some dependencies problem).
In the future I will use your patch.

I think that the problem is mine (not a colinux problem) because in
the OOP trace I have seen the "cocon" string.
I will post if I will have the same error or if the error vanishes.

Then I small idea ....
Don't you think that in the main Makefile a "make clean-kernel" is missing ?
The "make clean" only clean colinux daemon and driver, the kernel is
not touched.
But maybe you prefer do it manually.....

Thanks for your time !

Paolo
