Re: [ros-dev] [ros-diffs] [sginsberg] 35600: - Remove KEBUGCHECK and KEBUGCHECKEX macros - Replace "KeBugCheck(0)" by ASSERT(FALSE) - Replace deprecated "CPRINT" by DRINT1

KEBUGCHECK stops the execution also in release mode. For example, in ntoskrnl/dbgk/dbgkobj.c, code now continues even if DbgkpQueueMessage failed. Are you sure it is safe to continue in that case?

- In IoAcquire/ReleaseCancelSpinLock, use the queued "IopCancelSpinLock" instead of a ros-specific "CancelSpinLock" standard spinlock - Misc fixes

by Stefan Ginsberg

In the kernel, stdcall IoCallDriver is macroed to the fastcall IofCallDriver. However, for clarification I think that IoCallDriver should be used, and this is what we do everywhere else. >Why this? >> ====================================================================== >> --- trunk/reactos/ntoskrnl/io/iomgr/iofunc.c [iso-8859-1] (original) >> +++ trunk/reactos/ntoskrnl/io/iomgr/iofunc.c [iso-8859-1] Sat Aug 23 >> 11:30:14 2008 >> @@ -682,7 +682,7 @@ >> StackPtr->FileObject = FileObject; >> >> /* Call the Driver */ >> - return IofCallDriver(DeviceObject, Irp); >> + return IoCallDriver(DeviceObject, Irp); >> } >> >> /* >> @@ -732,7 +732,7 @@ >> StackPtr->FileObject = FileObject; >> >> /* Call the Driver */ >> - return IofCallDriver(DeviceObject, Irp); >> + return IoCallDriver(DeviceObject, Irp); >> } >> >> _________________________________________________________________ Discover the new Windows Vista http://search.msn.com/results.aspx?q=windows+vista&mkt=en-US&form=QBRE

Re: [ros-dev] [ros-diffs] [arty] 35581: Catch failure to release the cancel spinlock. Would've spotted my error in tcpip.sys.

by Alex Ionescu

--- Please, please, don't think I'm trying to say "revert this!" --- There are dozens (if not more) places in the kernel where such checks could/should be made. I believe the more correct approach instead of adding them to every function, is to use a similar framework to Microsoft's Driver Verifier, where such functions are hooked and wrapped through similar verifications. I'm not saying this particular assert should be removed, I'm just letting people know that if there's going to be major work on this -- there's a better way. Just my 2c.

Re: [ros-dev] [ros-diffs] [sginsberg] 35565: - In IoAcquire/ReleaseCancelSpinLock, use the queued "IopCancelSpinLock" instead of a ros-specific "CancelSpinLock" standard spinlock - Misc fixes

by Alex Ionescu

Please don't write formatting fixes as "Misc Fixes". It's a pain for reviewers who expect actual functionality fixes, and also for changelog writers, which will try to understand what exactly you fixed. Furthermore, such formatting patches should have [FORMATTING] attached to them. And finally, formatting patches should not be mixed with code patches. I know you're new to trunk, but perhaps you should read over the rules first. I appreciate your patches, but you have a bit of a cowboy attitude with your commits, which is bound to hurt someone in the end.

Re: [ros-dev] [ros-diffs] [tkreuzer] 35518: Implement KiSystemStartup in C instead of asm, implement KiSwapStack intrinsic, get rid of KiSetupStackandInitializeKernel, instead do the work in KiSystemStartupReal in C. Move Stack definitions into trap.S and get rid of the whole boot.S file. Comment out the sync loop for the moment and add a comment why it doesn't work (InterlockedBitTestAndSet64 doesn't work correctly).

by Thomas Bluemel

Calling from KiSwapStack from C seems quite scary. C doesn't know anything about you messing with the stack, so any subsequent code may still refer to a now invalid stack. There's a reason this was implemented in asm... tkreuzer(a)svn.reactos.org wrote: > Author: tkreuzer > Date: Thu Aug 21 16:16:57 2008 > New Revision: 35518 > > URL: http://svn.reactos.org/svn/reactos?rev=35518&view=rev > Log: > Implement KiSystemStartup in C instead of asm, implement KiSwapStack intrinsic, get rid of KiSetupStackandInitializeKernel, instead do the work in KiSystemStartupReal in C.

Has anyone given any thought to coding so that the OS can use the GPU

by Matthew Therault

Just a random thought wondering if anyone else has thought about it. They are making great strides into how the GPU can now be used as a processor. -- Two men walk into a bar....... Third one ducks.... Think about it, it will come to you. :P

Re: [ros-dev] [ros-diffs] [tkreuzer] 35458: Move some architecture specific code from KiRosPrepareForSystemStartup into KiArchInitSystem, defined for each architecture. Enable KiRosBuildReservedMemoryMap for _M_AMD64

by Alex Ionescu

Please rename the function to KiFreeLdrHackKiArchHackHack or something like that, and move it away from cpu.c, somewhere like i386/freeldr.c to make clear that this function has NOTHING TO DO with how NT should boot and is a hack because FreeLDR is a piece of shit that nobody seems to want to fix.
