Re: [ros-dev] [ros-diffs] [jimtabor] 44902: [Win32k] - Patch by Dan Kegel: Fix minor read buffer overrun in CombineRgn. http://bugs.winehq.org/show_bug.cgi?id=20851 - When locking and unlocking regions, use probe to check attribute space first before

To slow things down. ATM there is a fault created when the mouse moves with updates, creates and destroying region handles. The kernel fault occurs inside SEH which should not happen right? What we need is a semaphore that is used for the whole handle manager. This is my point over the years about the stability inside win32k. It running full bore, spinning out of control. Surprised it still works after turning everything on in my tree.

Sorry, it's not "forgotten" but rather "missing". WBR, Aleksey Bragin.

Trunk breakage
by Olaf Siejka 02 Jan '10

02 Jan '10

I would like to ask everyone to hold a bit with commits, as trunk has now regressed a bit. From revision 44885 (new pool code) we have crashes at several places: http://www.reactos.org/paste/index.php/6313/ clicking on My Computer http://www.reactos.org/paste/index.php/6311/ servman http://www.reactos.org/paste/index.php/6312/ The common part is ExAllocatePoolWithTag function. Arm Ninja Team is asked for fixes. Thanks in advance.

GCC 4.4.x -- What's missing?
by Alex Ionescu 02 Jan '10

02 Jan '10

Hi, As far as I am aware, GCC 4.4.x now works on Linux through RosBE 1.5 (minus some missing patches for 64-bit hosts), and I've gotten it to work on SnowLeopard with some minor hacks -- ie, all that's missing is for Colin, when he has time, to integrate the little fixes for these non-standard hosts. As for Windows, I think there is a fully working binary GCC 4.4.x/RosBE that builds trunk just fine. So what's missing for 4.4.x to become official, RosBE 1.5 to RTM, and for the 4.4.x patch from BZ to be committed (The one that gets trunk building)? Best regards, Alex Ionescu

MmSecureVirtualMemory
by Olaf Siejka 02 Jan '10

02 Jan '10

Could anyone please consider implementing the above? According to http://msdn.microsoft.com/en-us/library/ms802934.aspx - MmUnsecureVirtualMemory could be required as well. Lack of those functions is currently breaking up 3d acceleration passthrough with Virtualbox 3.1.0 and newer. Thanks in advance

Re: [ros-dev] [ros-diffs] [ros-arm-bringup] 44885: - Switch to using ARM3 paged pool -- all pool allocations are now handled by ARM3, which should be much more efficient, and combines both NP and P code together.

Re: [ros-dev] Ros-dev Digest, Vol 65, Issue 2
by Babar Shafiq 02 Jan '10

02 Jan '10

Hi All, Just want to say thanks for this wonderful project. Works like a charm in VritualBox image. It is unbelievable that total size of this great OS is just 37MB. In Virtual Box, default config for Video memory is too low which cause error on loading the VirtualBox image, after increasing it to 16mb all works fine. May be useful for someone else on the list. Waiting for the stable version to use on my laptop. Babar Shafiq Nazmi.
