With the question continually arising regarding the binutils issue, would it not be an idea to have an build announcement section on the site where notes can be placed for all to see. A lot of people don't use IRC or read the mailing list, so it might also be useful to keep people updated with the happenings in SVN too. e.g. when accept was committed, current status of USB, etc. Gedi ************************************************************************ The information contained in this message or any of its attachments is confidential and is intended for the exclusive use of the addressee.

This patch improves by around 15-20% (tested but not scientific) the speed of ReactOS on all hardware and virtual machines. Furthermore, it improves speed by over 50% (tested but not scientific) on hardware supporting the SYSENTER/SYSEXIT call pair. On VMWare however, due to causes still under investigation, SYSENTER/SYSEXIT must be disabled, or else there is a 3X slowdown. Vmwinst takes care of writing the Windows-compatible Value in the Registry, and it is read before choosing which kind of call to execute. This means that vmware is able to take advantage of the ~20% speedup, but not of all the full capability of this patch. It also combines the previous iface tools into a single, much more dynamic and small utility, which I called NCITool (Native Call Interface Tool). Although it is almost final, I still have to set-up the macros for portability and msvc compatibility, so this is a known issue (note however that the previous version suffered from the same incompatibilies). I will fix it during the week. I would like to thank Emanuelle and KJK::Hyperion for the original tool, and most of the parsing code has remained intact, apart from some code-duplication removal and simplification. The following two issues remain in this patch, which I will look at this week as well: 1) SMP. I have not tested SYSENTER on an SMP machine, and I believe that the MSRs must be written on other CPUs as well, perhaps using an IPI? 2) Pentium Pro. It erronously reports the SEP flag but does not support SYSENTER. Code must be added at the related FIXME in order to check for this. I have, along with others, tested this patch for more then a week now, and I have found no visible problems, apart from the VMWare weirdness. If any problems are noticed due to it, please post accordingly and I will have a look at it. Best regards, Alex Ionescu

Data types: compatibility and porting

by Emanuele Aliberti

Reading the forum, it seems that porting ROS to 64-bit (x86-64) is the most wanted target. Should we begin using (and converting existing code) the new data types MS defined for Win64, to make easy that one and any other future porting effort?

usb - UHCI, OHCI and EHCI implementations

by Ryan O'Connor

Hi, This is Polonium from the irc channel (although I’m not in there all the time) Just trying to gather what’s happening with USB support, more specifically the host controller interfaces that are required to lie below the usb device drivers. Is there anyone currently working on this? If not, are there any programmers who would like to solely focus on implementing, for example, a universal host controller interface for ReactOS. While I do not know much about the topic myself, with ample resources and team members I may be able to make a good start. Anyone else interested? The specifications for the interfaces can be found on the Intel website. Regards Ryan O’Connor --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

[PATCH] minor fix for RtlStoreUlong()

by d_layer

Hi, Attached patch should fix some problems of RtlStoreUlong(). 1) store SECONDBYTE of the value correctly. 2) store a ULONG value but not a ULONG_PTR value. There is RtlStoreUlongPtr() which stores a ULONG_PTR value. http://msdn.microsoft.com/library/en-us/kmarch/hh/kmarch/k109_2dd28516-e8e4… -- d_layer

Who want to help a newbie?

by yang

Hello everyone! I am a newbie, now I am a sophomore. I learn the C programming language last year. And one month ago I found this project, and begin to read the source code last three week. But I found there are to many thing that doesn't mention in my book. I can't undertand the source code. Who want to tell me what I had to study and answer some question as a teacher even if some question may be stupid. Thanks to help a chinese open source software fan. Regards, yang
