I was under the impression short-wchar could differ depending on the platform and thats why wide-characters were a no-no in wine. Or is it that only newer gcc's support this option?

Hi Royce: int highest_bit ( int i ) { int ret = 0; if ( i > 0xffff ) i >>= 16, ret = 16; if ( i > 0xff ) i >>= 8, ret += 8; if ( i > 0xf ) i >>= 4, ret += 4; if ( i > 0x3 ) i >>= 2, ret += 2; return ret + (i>>1); } Guys I think I have one of those optimizations manuals for asm that actually use only one multiplication by a called ¨magic number¨ to get the first bit set. I actually don´t want to trace this code in my head but if you are searching a fast BSF replacement... It was tested using brute force for the 2^32 possible values on the argumment. Maybe you could check the internet for ¨Agner Fog optimization¨. I have a very bad memory so maybe the name is wrong. This is all the info I can give until I get home. Ohh well i can do it myself: http://www.df.lth.se/~john_e/gems/gem0039.html It was Harley´s magic number. so I wasn´t that far. or you can read it here... I have a c version but I guess you don´t need that :) ---------------------------------------------------------------------------------------------------------- Fast BSF replacement ASM/80386 Macro EMBSF5 emulates the BSF instruction for non-zero argument <------------------------------------ remember to test for this!!!!!!! This macro utilizes an algorithm published in the news group comp.arch by Robert Harley in 1996. The algorithm converts the general problem of finding the position of the least significant set bit into a special case of counting the number of bits in a contiguous block of set bits. By computing x^(x-1), where x is the original input argument, a right-aligned contiguous group of set bits is created, whose cardinality equals the position of the least significant set bit in the original input plus 1. The input x is of the form (regular expression): {x}n1{0}m. x-1 has the form {x}n{0}(m+1), and x^(x-1) has the form {0}n{1}(m+1). This step is pretty similar to the one used by macro PREPBSF <http://www.df.lth.se/~john_e/gems/gem002e.html> , only that PREPBSF <http://www.df.lth.se/~john_e/gems/gem002e.html> creates a right-aligned group of set bits whose cardinality equals exactly the position of the least significant set bit. Harley's algorithm then employs a special method to count the number of bits in the right-aligned contiguous block of set bits. I am not sure upon which number theoretical argument it is founded, and it wasn't explained in the news group post. According to Harley, if a 32-bit number of the form 00...01...11 is multiplied by the "magic" number (7*255*255*255), then bits <31:26> of the result uniquely identify the number of set bits in that number. A 64 entry table is used to map that unique result to the bit count. Here, I have modified the table to reflect the bit position of the least significant set bit in the original argument, which is one less than the bit count of the intermediate result. I have tested the macro EMBSF5 exhaustively for all 2^32-1 possible inputs, i.e. for all 32-bit numbers except zero. Place the following table in the data segment: table db 0, 0, 0,15, 0, 1,28, 0,16, 0, 0, 0, 2,21,29, 0 db 0, 0,19,17,10, 0,12, 0, 0, 3, 0, 6, 0,22,30, 0 db 14, 0,27, 0, 0, 0,20, 0,18, 9,11, 0, 5, 0, 0,13 db 26, 0, 0, 8, 0, 4, 0,25, 0, 7,24, 0,23, 0,31, 0 And here follows the actual macro: ; ; emulate bsf instruction ; ; input: ; eax = number to preform a bsf on ( != 0 ) ; ; output: ; edx = result of bsf operation ; ; destroys: ; ecx ; eflags ; MACRO EMBSF5 mov edx,eax ; do not disturb original argument dec edx ; n-1 xor edx,eax ; n^(n-1), now EDX = 00..01..11 IFDEF FASTMUL imul edx,7*255*255*255 ; multiply by Harley's magic number ELSE mov ecx,edx ; do multiply using shift/add method shl edx,3 sub edx,ecx mov ecx,edx shl edx,8 sub edx,ecx mov ecx,edx shl edx,8 sub edx,ecx mov ecx,edx shl edx,8 sub edx,ecx ENDIF shr edx,26 ; extract bits <31:26> movzx edx,[table+edx] ; translate into bit count - 1 ENDM Note: FASTMUL can be defined if your CPU has a fast integer multiplicator, like the AMD. The IMUL replacement should run in about 8-9 cycles.

In copyright law it's the result that matter, not the process. To be protected by copyright law, it must be in tangible form. Looking at disassembled code is permitted by copyright law so it's only a problem if the person doing it lacks self-discipline and uses the disassembled code in a way that violates copyright law. That said, I don't believe there is a need for reverse engineering methods for implementing the majority of ReactOS and WINE. Our goal is to run Windows software on ReactOS and other free operating systems. We have some smart people on these projects. If the Windows software vendors could figure out how to use the interfaces using the public available documentation, then we can certainly implement the interfaces from that same information. If there is an interface that isn't documented, then certainly most Windows software won't use it and there is no need to implement the interface at all.

Re: I think I know how uxtheme works...

What I am doing here is clean-room reverse engineering. Essentially it involves taking existing binary modules and sources of information and writing up what they do in a way that isnt violating the copyright on the origonal (IANAL but I dont think what I posted violates the copyright on the windows binaries). Then it involves someone else who hasnt seen the origonal copyrighted source using the resulting information to re-implement whatever the information describes. As long as the person who origonally did the reverse engineering never contributes anything to the resulting code, it is (AFAIK, IAMAL) perfectly legal (after all, this is exactly what was done when the first clone PC bios was written, one group disassembled the origonal IBM BIOS and wrote up documents on how it works and how to talk to it. Then another group not connected to the people who did the origonal reverse engineering took the documentation and re-implemented the BIOS from just the documentation without looking at the orgininal IBM implementation) I never had any plans to actually write code for this (since doing so is out of my skill range) and as long as I never do so in the future (thus "tainting" the code I write as being a potential Derived Work of the microsoft code I looked at), I dont see any way that the results of this investigation could be considered a derived work of any microsoft code. Although if I have a mis-understanding of this situation, please point out what I am doing that would make code written by someone else using the information in my posts a Derived Work of microsofts origonal binaries.

Speed Tests (was: ping Alex regarding log2() for scheduler)
by Ash 24 Mar '05

24 Mar '05

Hello, I'd like to provide a small VS.NET project file with 5 different tests. - 46ffffe9 tells everything is alright with the function calculation - times are measured with QueryPerformanceCounter - loop run cnt: 0x2ffffff result orig function 46ffffe9 it took 1491052 result orig function inlined 46ffffe9 it took 1035547 result second proposal inlined 46ffffe9 it took 1244434 result optimized asm 46ffffe9 it took 1338367 result debug asm 46ffffe9 it took 8774815 The second proposal is the original proposal but more shifts - still slower tho. Interesting is the inlined version generated by MSVC, shaving off almost 1/3 of the overall time. Also stared as "optimized asm" - no gurantee on register safety tho ;) For portability and performance sake it should be considered to create a compiler macro. This function is terribly small, any optimisations inside are outweighted by the calling overhead in this case. The most impressive one is the original function inlined, althought the ASM would only work on x86. Please do not think about using 64k tables, thats what, 1/2 of a Sempron L2 cache? It would really really trash performance.

about changelog idea
by Magnus Olsen 24 Mar '05

24 Mar '05

Hi Why not create two diffrent changelog for each release. one that contain all svn commit msg next one is what is benefit for the user. I think this is good idea. ´Then the user can read what new for them. If some want really know what we have done. Then they can read all commit msg. I think this is good idea, and will benfit alot of people.

I would think that ReactOs is not anywhere near being ready for themeing partially because it needs to write much more of the system software. Themeing can always be an option later. I have mentioned an alternate filesystem, and other services, but since I have not submitted code, people on the mailing list think i can not program something of the sort. I think it is great that people are wanting to understand the process of themeing but keep in mind that loading a theme may cut down on the resources available to the opertating system or may interfere with someone elses environment. > > From: Jonathan Wilson <jonwil(a)tpgi.com.au> > Date: 2005/03/23 Wed PM 09:19:23 EST > To: wine-devel(a)winehq.org, ros-dev(a)reactos.com > Subject: [ros-dev] I think I know how uxtheme works... > > What I strongly suspect happens is this: > 1.The themes service is always loaded and running and holds the theme data > (and it contains details of which .msstyles file to use) > 2.At some point (either at startup if the changes are global or when an app > loads if the changes are app specific, I cant find where this bit happens > but I suspect the themes service does this) control passes to ordinal 34 in > uxtheme.dll (aka ThemeHooksInstall acording to uxtheme.pdb).

If I remeber right Eirc Kohl offered to release some of his work to Wine for the binary format so you might want to ping him about the implementation details.

I rm -fr'd my reactos tree and did a clean CVS checkout and things are cool now. I guess the current build system left some crap around that caused problems. Nice work btw on the smss stuff. How much trouble do you think it would be possible to make a native mode console application in smss like the Windows recovery console? I have been thinking about doing this for the boot CD for a while but would like to make it more powerful than the Windows recovery console.

What I think of doing is: keep the boot registry as is (more less). Put in on wine/wine/config a key system that enables a "plugin" system of registry loaders/savers. Builtin plugins are current format and Windows binary format. Other formats could be easily implemented; candidates could be XML, MySQL etc... The system I thought of would also save the hives and sub trees, to the files/plugins it was loaded from. Each plugin could also implement a write behind so Data don't get lost in case of a crash or power lost. Good point with the on demand-loading/cache of keys. It should be done this way. So in summary: 1. Implement a Memory registry with plugin drivers and mount semantics. This driver goes here, that driver mounts there. 2. Implement 2 basic drivers: Wine builtin format, Windows binary format. 3. Enable dynamic load of external drivers. The Initial registry system is always loaded from system.reg builtin format which is also the "fstab" file of the registry. At minimum every thing is exactly like now one (two) files builtin format, and that's it. At the maximum it can be highly object oriented with per user, per application, per group management. Please tell me what you think. Any libraries I should look into? How is ReactOS's current (future) system? Free Life Boaz

RC1 of ros 0.2.6 is out
by Robert Köpferl 21 Mar '05

21 Mar '05

Hi, I just finished uploading the RC1 to sf.net The last build worked quite well, but improvements to the branch are welcome. If no major issues occour, we may perhaps advance to Release as next step, already. BTW: RosApps is from 2003, still. They are already in the installation, aren't they? So should they be hidden?

Serial port IRQ detection
by Mark Junker 21 Mar '05

21 Mar '05

Hi, is there a requirement for the serial port IRQ detection? This was also part of my old sources but currently I simply don't know how to do it inside the ReactOS serial driver. BTW: How does the "serenum" stuff works? Regards, Mark

Serial port type detection
by Mark Junker 20 Mar '05

20 Mar '05

Hi, I found some old sources from me where I detect the IRQ and the type (8250, 16450, 16550, 16550A) of a COM port. I converted the type detection sources to C. The detection if there is a COM port at all is made by inverting all bits of the LCR twice. All chips > 8250 have a scratch pad and all 16550A+ have a usable FIFO. I attached the diff for reactos/drivers/dd/serial/legacy.c. BTW: I'm sorry about it but my editor always changes TABs to spaces ...

Update reported version to Windows 2000 (Service Pack?)
by Steven Edwards 20 Mar '05

20 Mar '05

Hi, Most of the dev team seems to be in agreement with bumping the reported version number to Win2k but if anyone has any objections speak now or forever maintain a patch. I need Win2k to be reported as the version number as many newer applications such as Office 2003 will not install unless that is the latest version. If you find any places where a function, resource or anything reports a value as NT4 or something ReactOS dependant please change it to match Windows 2000 behavior. Also I propose we just report Service Pack 4. Thanks Steven __________________________________ Do you Yahoo!? Yahoo!

This is the text of the final few seconds before the compilation ran out of steam. The compiler is the standard MinGW32-gcc plus MinGW-g++, etc, in the MinGW-3.1.0-1.exe package; the computer's a Compaq 4000 Deskpro; the OS is MS Win95, bog-standard as far as I know.
