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

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

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.

FreeLoader now multiboot compliant

by Ge van Geldorp

Freeldr can now be loaded as a "multiboot kernel" by multiboot compliant bootstrap loaders like Grub. To load FreeLoader from Grub use something like this: title ReactOS root (hd0,0) kernel /freeldr.sys You can also override settings in the [FREELOADER] section of freeldr.ini by passing them on the command like, like this: title ReactOS root (hd0,0) kernel /freeldr.sys DefaultOS=ReactOS TimeOut=0 title ReactOS (Debug) root (hd0,0) kernel /freeldr.sys DefaultOS=ReactOS_Debug TimeOut=0 After selecting "ReactOS" from the Grub menu you won't have to make another selection on the freeldr menu because of the "TimeOut=0" Gé van Geldorp.

Hi, it seems you have forgot to change the named pipe and mail slot driver. - Hartmut > -----Original Message----- > From: ros-cvs-bounces(a)reactos.com > [mailto:ros-cvs-bounces@reactos.com] On Behalf Of ion(a)cvs.reactos.com > Sent: Sunday, October 31, 2004 3:40 PM > To: ros-cvs(a)reactos.com > Subject: [ros-cvs] CVS Update: reactos > > > CVSROOT: /CVS/ReactOS > Module name: reactos > Repository: reactos/include/ddk/ > Changes by: ion(a)mok.osexperts.com 04/10/31 15:40:11 > > Modified files: > reactos/include/ddk/: iotypes.h > > Log message: > Mailslot/Named Pipe structures. > > _______________________________________________ > Ros-cvs mailing list > Ros-cvs(a)reactos.com > http://reactos.com/mailman/listinfo/ros-cvs >

Guarded mutex

by Aliberti Emanuele

I found a note, in Kernel Mustard's (Steve Dispensa) blog, about guarded mutexes, which is a completely new synchronization object to me. typedef struct _KGUARDED_MUTEX ULONG Count; PKTHREAD Owner; ULONG Contention; KGATE Gate; WORD KernelApcDisable; WORD SpecialApcDisable; ULONG CombinedApcDisable; } KGUARDED_MUTEX, *PKGUARDED_MUTEX; What are they? KM says they are less expensive than FAST_MUTEXes. By the way, what is a KGATE? Emanuele
