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

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.

I guess you'll be claiming your Millennium Prize now. (For the uninformed: http://en.wikipedia.org/wiki/P_versus_NP_problem) On 2010-01-02, at 11:17 AM, ros-arm-bringup(a)svn.reactos.org wrote: > and combines both NP and P code together. Best regards, Alex Ionescu

Re: [ros-dev] Ros-dev Digest, Vol 65, Issue 2

by Babar Shafiq

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.

Re: [ros-dev] [ros-diffs] [ros-arm-bringup] 44871: NMI Support Patch 10: [NTOS]: Write barebones NMI Trap handler which does a TSS context switch to the NMI TSS and then calls the HAL NMI handler. [NTOS]: Implement KiSaveProcessorState for doing a PRCB context save/restore. You should now be able to test the new NMI functionality by either building the circuit referenced in my e-mail and attaching it to your PCI bus, or by using "nmi 0" in the QEMU stdio console.

Re: [ros-dev] [ros-diffs] [ros-arm-bringup] 44856: NMI Support Patch 5: [HAL]: Do correct TLB flushing for systems with global page support. [HAL]: Clean leading whitespace and comments.

by Alex Ionescu

Why don't you cache this instead of querying it for each TLB flush? Seems stupidly wasteful -- I thought the point was to "make it better"?? Isn't this what HalpGetFeatureBits is for?

So you're adding functions from the x86 HAL in NT6 to our NT5.2-targeted AMD64 HAL? Is it just me who gets confused here? If it's alright, I'd like to hear some explanations. Best regards, Colin

Re: [ros-dev] [ros-diffs] [tkreuzer] 44840: [HAL] Replace the asm implementations of HalpAcquireSystemHardwareSpinLock and HalpReleaseCmosSpinLock with C implementations. The old ones didn't work on SMP, as they were only compiled once as UP.
