ReactOS eating CPU time
by Casper Hornstrup 16 Nov '04

In VMware, ReactOS eats up all available CPU time. Does anyone have an idea why? Does it also do this on real hardware? Casper

RE: [ros-diffs] [CVS reactos] Fix handling of debug traps in GDB stub/KiDispatchException.
by Hartmut Birr 14 Nov '04

14 Nov '04

Hi, this changes breaks the handling of exceptions if KDB isn't set. In KiDispatchException the variable Action is preinitialized with kdContinue. After your changes, KiDispatchException does always return without any action. After this changes, I'm not able to install reactos. At the second stage setup I do never see the reboot page. - Hartmut -----Original Message----- From: ros-diffs-bounces(a)reactos.com [mailto:ros-diffs-bounces@reactos.com] On Behalf Of Gregor Anich Sent: Sunday, November 14, 2004 12:00 AM To: ros-diffs(a)reactos.com Subject: [ros-diffs] [CVS reactos] Fix handling of debug traps in GDB stub/KiDispatchException. _____ reactos <http://cvs.reactos.com/cgi-bin/cvsweb/reactos> /ntoskrnl <http://cvs.reactos.com/cgi-bin/cvsweb/reactos/ntoskrnl> /ke <http://cvs.reactos.com/cgi-bin/cvsweb/reactos/ntoskrnl/ke> catch.c 1.51 <http://cvs.reactos.com/cgi-bin/cvsweb/reactos/ntoskrnl/ke/catch.c?rev=1.51& content-type=text/x-cvsweb-markup> - <http://cvs.reactos.com/cgi-bin/cvsweb/reactos/ntoskrnl/ke/catch.c.diff?r1=t ext&tr1=1.51&r2=text&tr2=1.52&f=h> > 1.52 <http://cvs.reactos.com/cgi-bin/cvsweb/reactos/ntoskrnl/ke/catch.c?rev=1.52& content-type=text/x-cvsweb-markup> diff -u -r1.51 -r1.52 --- catch.c 11 Nov 2004 12:27:40 -0000 1.51 +++ catch.c 13 Nov 2004 23:00:15 -0000 1.52 @@ -16,7 +16,7 @@ * along with this program; if not, write to the Free Software * Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. */ -/* $Id: catch.c,v 1.51 2004/11/11 12:27:40 ekohl Exp $ +/* $Id: catch.c,v 1.52 2004/11/13 23:00:15 blight Exp $ * * PROJECT: ReactOS kernel * FILE: ntoskrnl/ke/catch.c @@ -80,13 +80,13 @@ else if (KdDebuggerEnabled && KdDebugState & KD_DEBUG_KDB) { Action = KdbEnterDebuggerException (ExceptionRecord, Context, Tf); - if (Action == kdContinue) - { - return; - } } #endif /* KDBG */ - if (Action != kdDoNotHandleException) + if (Action == kdContinue) + { + return; + } + else if (Action != kdDoNotHandleException) { if (PreviousMode == UserMode) { @@ -94,7 +94,7 @@ { PULONG Stack; ULONG CDest; - char temp_space[12 + sizeof(EXCEPTION_RECORD) + sizeof(CONTEXT)]; // FIXME: HACKHACK + char temp_space[12 + sizeof(EXCEPTION_RECORD) + sizeof(CONTEXT)]; /* FIXME: HACKHACK */ PULONG pNewUserStack = (PULONG)(Tf->Esp - (12 + sizeof(EXCEPTION_RECORD) + sizeof(CONTEXT))); NTSTATUS StatusOfCopy; @@ -125,10 +125,11 @@ } else { - // Now it really hit the ventilation device.

Our ne2000 driver and tcpip
by art yerkes 14 Nov '04

14 Nov '04

I found the bug in our ne2000 driver that perplexed filip. The bug was that the meaning of the PACKET_HEADER part in ne2000 that was skipped was a simple header put on each packet to determine what buffer page would be used next. This header is only 4 bytes and has nothing to do with the ethernet frame header. I've now factored in the ethernet frame header and made tcpip work the right way, that is to remove consideration of the ethernet frame header at layers above lan in the receive pipe. This should make all adapters work the same way for larger packets (and ne2000 now work right). I found few references to how this actually works so I could still be wrong, but I'm going on what filip said and this: http://cvs.sourceforge.net/viewcvs.py/openh323/pwlib/tools/PacketVxD/epacke… Which basically confirms filip's opinion. Please try it out. -- Here's a simple experiment. Stand on a train track between two locomotives which are pushing on you with equal force in opposite directions. You will exhibit no net motion. None the less, you may soon begin to notice that something important is happening. -- Robert Stirniman

Just came across this: http://www.genesi.lu/ Appears to be a new PPC based platform with published specs - would be great to have ROS running on this! Cheers Jason

RE: [ros-cvs] CVS Update: reactos
by Hartmut Birr 12 Nov '04

12 Nov '04

Hi, I think some of your changes in apc.c are wrong. Apc's are always thread local. They have nothing to do with the dispatcher database lock. The only locking object is the ApcQueueLock from the thread structure. - 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: Thursday, November 11, 2004 2:24 PM > To: ros-cvs(a)reactos.com > Subject: [ros-cvs] CVS Update: reactos > > > CVSROOT: /CVS/ReactOS > Module name: reactos > Repository: reactos/ntoskrnl/ps/ > Changes by: ion(a)mok.osexperts.com 04/11/11 14:23:53 > > Modified files: > reactos/include/ddk/: kefuncs.h ketypes.h > reactos/ntoskrnl/include/internal/: ke.h ps.h > reactos/ntoskrnl/ke/: apc.c process.c wait.c > reactos/ntoskrnl/mm/: marea.c virtual.c > reactos/ntoskrnl/mm/i386/: page.c > reactos/ntoskrnl/ps/: psmgr.c > > Log message: > Kernel: > - apc.c: Fixed some bugs and used Dispatcher Lock. > Simplified some functions and renamed/inlined others. > - wait.c: Fixed some assumptions about Dispatcher Lock > and Waiting/Alertability > - process.c: Fully implemented KeStackAttachProcess and > KeStackDetachProcess.

ReactOS Versions
by Rick Langschultz 12 Nov '04

12 Nov '04

When ReactOS is built and runs windows executables stabily I think we should have a program for windows that will let you customize the platform like windows ce and compile it with all the features you want. I think that it would be a great idea because of different types of systems such as PBX/VOIP servers, application servers, and domain name servers. This would allow security to be integrated into ReactOS by limiting programs allowing open ports, and Denial of service attacks. Maybe even support for multiple architectures like SH, ARM, X86, AMD64, PPC??? With FAT, FAT32, NTFS, XFS, EXT3, EXT2, and many others. Maybe even a rom based os. Please tell me what you all think.

taskmgr crashes in regobj.c - CmiObjectParse on Virtual PC
by Theodor Willax 12 Nov '04

12 Nov '04

Hi, I'm getting repeatedly kernel crashes in regobj.c - CmiObjectParse (line 168). To reproduce the crash start task manager with a right click on the taskbar, minimize this instance of taskmanager and start a new one. Here the code ---- else { if ((FoundObject->KeyCell->Flags & REG_KEY_LINK_CELL) && !((Attributes & OBJ_OPENLINK) && (EndPtr == NULL))) { DPRINT("Found link\n"); RtlInitUnicodeString(&LinkPath, NULL); ---- FoundObject->KeyCell is NULL. Does anybody else have the same problem? I've attached two screenshots of the BSODs. Clean compile of last cvs snapshot.
