Re: Virtual PC with ReactOS 0.3.8 : ok

What I meant by hardcoded is that the addresses of COM1, COM2, etc is hardcoded in kdcom. It doesn't seem to use the information that it gets via PNP in the normal serial mode driver that a userland program would call through.

Re: Virtual PC with ReactOS 0.3.8 : ok

Originally I had tried attaching the debugger to both COM ports with no success. I can make the following observations however. From userland, the COM ports seem to work, but they are reversed. Win2K running under VirtualPC doesn't have this problem, and VirtualPC doesn't have an option to swap the ...

Re: Virtual PC with ReactOS 0.3.8 : ok

For VirtualPC (technically VirtualServer), I get (in this order): (drivers\serial\serial\pnp.c:218) New COM port. Base = 0x2f8, Irql = 24 (drivers\serial\serial\pnp.c:226) Comparing addresses: KdComPortInUse: 00000000, ComPortBase: 000002F8 (drivers\serial\serial\devctrl.c:67) SerialSetBaudRate(COM1...

Re: ReactOS Roadmap: version 0.3.11

You are not really that long with us to witness any gcc-related suffering, but believe me, it exists. For example, its a source of our reluctance towards any c++ code. It's funny - we went through the same thing some 10-15 years ago with Linux. Some wanted C++, others felt the compiler wasn't stabl...

Re: Virtual PC with ReactOS 0.3.8 : ok

Update: I have spent some time fooling with this, and there are some rather strange things going on under VirtualPC. Essentially I can't get anything working at all that involves COM ports and the kernel using VirtualPC. No GDB, no KDB, no DebugPrint messages. If I attempt to use Tab-K, the system f...

Re: Virtual PC with ReactOS 0.3.8 : ok

Possible, I guess. The problem I see on VirtualPC is that the mouse moves in a very jerky fashion - almost as if it is polling the device every second or two instead of responding immediately to interrupts. And for that matter, double-clicking doesn't work on VirtualPC. The queueing issue in the bug...

Re: Virtual PC with ReactOS 0.3.8 : ok

I am trying to play with this some to figure out what the issue with the mouse is. What I would like is to get the various logging things in the i8042 driver to be written somewhere - ideally to the COM port where I can see it in putty. But so far I get no output.. I hacked i8042prt.c to have this: ...

Re: ReactOS Roadmap: version 0.3.11

I just submitted a bug with a testcase - 4711. What seems to happen is that the child process starts running and the debugger never gets any debug event notifications. In my case, the child test is just a hello world program, so it runs and exits. I have this vague recollection that some of this use...

Re: ReactOS Roadmap: version 0.3.11

Currently as an interim measure we have RosDbg and Kdbg, both found on the wiki. Yeah, I know. But to use it, it seems like you have to be in a position to do your own custom build with special flags set, and for those of us who don't really have the time that is a pretty big hurdle. Really what I ...

Re: ReactOS Roadmap: version 0.3.11

One thing I would like to request is that someone work on windbg and cdb and fix reactos so that these are stable and usable debuggers. I spent some time playing with ReactOS, and I have a list of close to 30 issues. A few of them I have seen discussed, most I have not. Some would in fact be difficu...

Re: Translating the BSOD

But in the end, wouldn't it be far more helpful to add support for doing a memory dump when the kernel crashes rather than just translating the actual blue screen? The trick is to find a place to write the thing, and you don't really know what you can trust in the kernel. I am guessing you could dum...
