Snow Leopard xnu kernel test patch
 

http://rapidshare.com/files/28528776...-AnV_test.diff
I can't compile it since I use Leopard and xcrun doesn't work under it.
Could somebody please do a test build for me?
NOTE: It could still contain a few errors or mistakes at this time.
Enjoy this new test patch... ;)

how apply the patch?

Download from opensource.apple.com these packages, and build it.

cxxfilt-9.tar.gz
dtrace-78.tar.gz
kext_tools-177.tar.gz
bootstrap_cmds-72.tar.gz

I can compile the original sources but the patched not. I get this error:

W00! i cant wait!! im SO looking forward to Snow Leopard!!!!

getsectdatafromheader is declared in <libkern/kernel_mach_header.h>
you should put #include <libkern/kernel_mach_header.h> into the failing header
That should fix this up

patch -p0 -i xnu-1456.1.26-AnV_test.diff

from the directory you have both the patch and the sources in (in xnu-1456.1.26)

I have the same error as rbm, without patching compile, and patched no.
I take a look at headers, and libkern/mach_kernel_header.h is include under ifdef kernel argument.

What do we have to do after running, patch -p0 -i xnu-1456.1.26-AnV_test.diff?
Thanks!

As I understood you in another posts, this will never work in 64-bit mode on AMD. True?

Should the "Missing }." that is mentioned in RMB post also be caused by a missing inclusion of the libkern/kernel_mach_header.h?

Where should it be included, as perisman mentions it seems to be (conditionally) included in bsd/sys/linker_set.h?

To me its unclear what is is causing this error were.

Could you shed a light on it a bit further Andy?

Cheers! :)

I guess _SYS_LINKER_SET_H_ is not defined (should it be?), cause if code in libkern/libkern/kernel_mach_header.h is changed to :

//#ifndef _SYS_LINKER_SET_H_
void *getsectdatafromheader(kernel_mach_header_t *, const char *, const char *, unsigned long *);
//#endif

the compile errors in linker_set.h regarding getsectdatafromheader disappear.

Cant seem to find though where this error:

MIG task_access_server.h
Missing }.

is caused...

btw, "why is the rum gone?" :-)

sse3emu.c:

/////////////////////
#include <stdint.h>

/* kaitek: the SSE3 emulator is automatically disabled if sse3emu_size is zero. */

const uint8_t sse3emu_data[] = { 0x00 };
const uint32_t sse3emu_size = 0;
/////////////////////



Ohno! No SSE3 emulator in 32bit after all? | -)

Somebody compiled this yet? Can't wait :D

Sure it will...
But not on SSE2 only machines

I could add that afterwards but lets first get this fixed up and working...

Check task_access_server.mig...
Try manually migging it and check for errors, then let me know...

i have an AMD machine running SL in 32 bit mode with this metode : http://www.infinitemac.com/f57/amd-s...install-t3727/ , will try to compile it tonight... hope i can help creating 64 bit XNU kernel..

Could you give me some hints on howto do that please?

look for the file in spotlight
use /usr/bin/mig <file.mig> to try to mig it...
Check the returned info + files + line

I've compiled xnu-1456.1.26 by following this guide: http://shantonu.blogspot.com/2009/09...-has-been.html

I have a Pentium-D so these are the minimum changes that need to be made to get it to boot:

changes
===============

* remove the CPUID checks in cpuid_set_info() in osfmk/i386/cpuid.c: Specifically the cpuid_family and cpuid_model panic

* change 'cpufamily = CPUFAMILY_UNKNOWN' to 'cpufamily = CPUFAMILY_INTEL_6_14' in bsd/kern/kern_mib.c

* comment out cpuid_family check in tsc_init() on line X in osfmk/i386/tsc.c. Specifically comment out this code:

if (cpuid_info()->cpuid_family != CPU_FAMILY_PENTIUM_M) {
panic("tsc_init: unknown CPU family: 0x%X\n", cpuid_info()->cpuid_family);
}

* comment out following lines in commpage_stuff_routine() on line X in osfmk/i386/commpage/commpage.c:

if ((cur_routine!=0) && (matched==0))
panic("commpage no match for last, next address %08lx", rd->commpage_address);


A few more changes are needed to get x64 support but before I add that, I wanted to get 32bit mode to work.

With the above changes, the kernel boots but it hangs after the 'BSD root: disk0s2, major 14, minor 2' print. Normally after that it prints a few 'com.apple.launchd' lines but not with the kernel that I built and I don't know why. Any ideas?

I cant find task_access_server.mig in spotlight...
Fixed the, getsectdatafromheader error with this like never_mind said:

//#ifndef _SYS_LINKER_SET_H_
void *getsectdatafromheader(kernel_mach_header_t *, const char *, const char *, unsigned long *);
//#endif

Putting in #include <libkern/kernel_mach_header.h> into linker_set.h did however not work...

Check where PADL_ and PADR_ are defined and make sure the corresponding header file is included.
Also I've read somewhere else that there might be missing #endif directives to #if directives in some of the headers.
Perhaps you should investigate?

It seems that their defined in mach_traps.h...
Not sure which header file to include...

I'm not sure where they are in but if they are for example in osfmk/i386/mach_traps.h
you #include <i386/mach_traps.h>
Just an example...
Check the base path and include it before the definitions
Also check for those unmatched #if s
I have bought an external HD so I'll be on Snow myself soon ;)

Nice to hear that Andy, looking forward to AnV snow kitty kernel :)

I am not pleased with the modbin kernel...
It panics right after init :(
I'm not able to install SL on my external HD :-/

What does the kernel panic say andy? Did you tried the test7 kernel?
I haven't had the time too check on the error while compiling yet...
Hope you can figure it out :)

Hi Andy,

migging the .h file (there's no .mig files?) is giving me buckets of error, but also on other .h files, so I am probably not doing it right.

But what I found is that , the "missing }." is caused by a missing newline in osfmk/conf/MASTER.i386

Seems hard to believe? Just open osfmk/conf/MASTER.i386 , go to the lastline, slam some <returns> (ok 1's enough) into the file (so, at the end) and after that the error is gone.

Tough one!

Let's see about this next error..

BBL! :)

p.s.

this is what diff gave me (opendiff didn't show me this, annoying!!!):

80,84d79
<
< # added builtin decryptor functions
< #
< options BUILTIN_DECRYPTER
< #options BUILTIN_DECRYPTER_VERBOSE
\ No newline at end of file

Me neither! ;-)

Need custom kernel with SSE3 emulator, or no go :)

Forward we go! :)

p.s. why are you not able to install it on external hd??

It crashes after basic initialization with reason : unknown...
Seems my CPU isn't supported on that kernel (Intel Celeron M 420)

Since the installer can't load up due to the not working kernel...
I tried installing from USB HD

Oh hehe, i thought you tried to install via OSinstall.mpkg...

Need that kernel too ;)

BTW, I am compiling the SL kernel on LEO. That of course doesn't really work, but what I can do is compile most, so I can at least check for compile errors. I've installed 10.6 SDK headers manually in Leo. I even managed to compile one kernel at some point, but it gave my a brick due to linker errors. I know I need 10.6 compiler/linker/tools etc to really make it, but in Leo i've been able to compile to check for syntax errors etc using some tricks.

Are you also compiling this way now Andy? I understand you are not running SL so far either..

Got a lil further, still allot of errors...

Also on pastebin: http://pastebin.com/m24986ef1

PE_parse_boot_arg should be replaced with PE_parse_boot_argn
example: PE_parse_boot_arg("argument", &var) -> PE_parse_boot_argn("argument", &var, sizeof(var))
PADL_ and PADR_ you should look up and make sure bsd/vfs/vfs_attrlist.c has the header included before bsd/sys/sysproto.h

I also found a way to do it by removing -Werror and making sure it doesn't use xcrun for the tools in makedefs/makeinc.cmd + various Makefiles
I've been thinking of writing a little xcrun tool which does the same without changing it (just printing the tools statically e.g. xcrun -find mig should return /usr/bin/mig)

Yes it worked when i added the the right PE_parse line, but i dont think i have the knowledge/time to go any further with it...

One question, what do i need to get rid of this;
Thanks!

Add to makedefs/MakeInc.def on top:
export BUILD_STABS = 1

Thanks man ;) Was kinda annoying when compiling :p

No problem ;)

k so does this mean we have a working Voodoo kernel? cause im dying here... my Leo install is ALL messed up and I dont want to erase it.. it has a LOT of stuff i need.. its what I get for not buying a TM backup disc...

Ok so vfs_attrlist.c is in bsd/vfs/
And mach_traps.h is in osfmk/mach/

Should i add;
#include <osfmk/mach/mach_traps.h>
To vfs_attrlist.c?

And Andy wouldn't it be easier if you would maybe remotely control my pc to test? :p

yes... before the inclusion of the "bad header"
P.S. Sorry... I'm using a win PC right now... can't remotely control... :(

teamveiwer!! cross platform lol

Hmm tried that, said it couldn't find the directory/file
I used a VNC server for remote control. Should work with any VNC Viewer for windows too :)
But its 23:00 here now and i need to get up at 6:45.
So maybe we can remote control tomorrow...

Yeah... same time here... 22:58...
Also is early day for me tomorrow but I'll continue a little bit longer ;)

I had the same problem with my box. I tried a different boot file and that fixed it. The 'debug boot' file listed here: http://www.insanelymac.com/forum/ind...owtopic=181699 worked for me as does the new Chameleon 2.0 RC3.

Morning ;)

I get these errors now:

That stuff it errors on is defined in osfmk/i386/mp.c, but I don't get how this should be available in osfmk/i386/i386_init.c. Does it need to be compiled before i386_init.c (i guess its a global define or so??)

Any thoughts?

what is sysproto.h use for?

wait, now i get it, slave_tsc_init moved, so i guess those declarations need to go somplace else..
