KMODE_EXCEPTION after pressing Cancel button in Taskbar Settings dialog
by Theodor Willax 04 Nov '04

04 Nov '04

Hello, I'm getting repeatedly a KMODE_EXCEPTION when pressing the Cancel button in the Taskbar Settings dialog. See both screenshots attached. I got this blue screen with several versions of the 0.2.5 cvs tree on my virtual pc. The last build I did with the cvs tree from yesterday evening. How could I debug this error? Thanks, Theo _________________________________________________________________ Machen Sie lästigen E-Mails ein Ende.

Re: [ros-dev] connect gdb to named pipe in ms virtual pc session

Hello Filip, I see what your patch should achieve. But pipetunnel doesn't work although I defined out the serial port detection code according to your patch. I will post if I'm successful in getting pipetunnel to work on virtual pc.

Using zones in NTOS
by Aliberti Emanuele 03 Nov '04

03 Nov '04

What are the advantages in using zones when allocating memory in kernel mode? Are there other ways to pre-allocate an address range to be used for small memory objects management (NP pool)? Emanuele

Some more questions: a) Do I need to compile the cvs snapshot with special make options to debug trough serial ports? b) Works the named pipe approach with ms virtual pc? c) Do I need a special gdb version?

address of a variable
by Hartmut Birr 03 Nov '04

03 Nov '04

Hi, if I have address of a variable in the bss section from ntoskrnl, how can I find out the name? Searching into the map file doesn't help. Possible the address is a pointer into a structure. - Hartmut

connect gdb to named pipe in ms virtual pc session
by Theodor Willax 03 Nov '04

03 Nov '04

Hi, could anybody tell me how to connect gdb.exe to my named pipe "\\.\pipe\roscom2" of a virtual pc session (on virtual com2 port). I'm running gdb on Win XP SP2 and use ros 0.2.5-cvs last updated 11/03/04. I set up "pipetunnel.exe roscom2" in one command prompt window, started virtual pc session in debug mode and now try to connect gdb to pipetunnel. pipetunnel is now listening on tcp port 9999.
