[AMD] Yosemite Kernel Testing (for help use the Help Topic)

Kaya80 · January 26, 2015

Can I safely update to 10.10.1 on AMD or have to do something before replacing the kernel?

tatomi92 · January 26, 2015

With BSA_YOS_R7D system overall performance is very good (Geekbench score is much lower than on Mavericks), but wrong colors in Launchpad, Safari and login screen! Appstore works!

With 1010-anv-r7-kernel.zip almost the same experience, but also wrong colors in Desktop.

Is there any fix for that?

Not untill we know what causes this. We'll need to check all instructions.

New kernel to test.

I again modded it to software data types.

Hopefully with more success now.

BSA_YOS_R7D

Hi Andy,

i test the version X86_64_R7D with webkit.

up to now very stable, app store works, safari once (within one hour) an error message brought.

the color are clear, youtube runs well.

I installed additionally the safari picture preview kit.

Without the two kit unfortunately safari crashes, App Store can not correctly be opened, Preview Picture are distorted / in Safari are not correctly represented.

thanks

I now have access to a real AMD Athlon II X2.

It's my aunts PC which I am allowed to use.

I just converted a Chameleon based image to a vmdk (dd2vmdk) and I set the following configuration in the VMX file to enable full support.

I can now thus test out some specifics...

A tad slow (boot takes very long) but at least it works...

I will install a VMWare virtual machine and use my latest AMD kernel in order to make it work and do tests.

I also noticed on boot some things were misplaced (Black blocks on the installer which seemed to disappear after a while).

NOTE: I used Chameleon on a USB stick (and Yosemite installer), converted this to a raw image and then I made the vmdk config.

Perfect thus for hackintosh testing on AMD in VMWare Virtual Machine.

This works without any unlocker in VMWare Workstation versions even up to 11!

Oh yeah, before I forget, the download for dd2vmdk:

http://dd2vmdk.sf.net

The irony wants... so far I see no pixel bug further.

Seems to be video driver related... we should examine the video drivers in more detail...

Maybe framebuffer issues???

Some part of the code must cause this and it's either the IOFramebuffer or the IOAccelerator that causes it...

If it's IOFramebuffer related - we can make our own... the IOFramebuffer class is fully documented by Apple and fully open for anyone to use. VMWare has an open source graphics driver too...

http://sourceforge.net/projects/VMsvga2

A example of an Apple made IOFramebuffer is NVDAResman.kext.

Attached is an open source snapshot of the drivers inside VMWare.

If it's IOAccelerator related - we can only patch... in order to make an IOAccelerator we would need to implement every OpenGL instruction till OpenGL 4.

Since they're not openly coded I don't know how they work and can't thus make an IOAccelerator.

Other than that it contains only start / stop / probe (standard IOKit functions). an example of an IOAccelerator is NVDANV50Hal.kext.

EDIT: It would seem the VMWare project contains a very basic IOAccelerator.

It's only capable of accelerated block transfer (blit) functions but it's a start...

We would need to add Apple's OpenGL functions though if we wanted to make our own... this plainly will not do for HW acceleration in any way.

Only accelerated drawing is the result of this driver... not more...

The most up to date version is the 2D GL branch.

This would need still the 3D enhancements but it's nice to see these are openly coded....

Obviously some Yosemite tweaking would be required too!

Interesting chunk of code above.

Selecting the graphics device.

This would need tweaking to Intel HD in order to make it work with Yosemite.

Some functions may also need changing...

Judging by code above: it seems to emulate a GMA950...

It's still cool to know how that works thus...

Next cool piece of code - Same thing the code defining the CGL renderer...

Would also need Intel HD..

And yet another reference to the renderer id...

Would seem it really needs updating...

It also seems to implement the OpenCL engine (not bad!)

gldGetRendererInfo -> needs mods too!

Also sets a renderer id... I'm starting to think most older no more supported cards could be supported these days using a properly coded IOAccelerator.

With all of that info it should actually be possible (and with some extra reverse engineering) to make our own!

OpenCL is implemented through the gldCreateComputeContext and gldCreateComputeContext functions (that and some extra functions).

gldInitDispatch defines apparently the supported OpenGL functions...

Interesting...

Wow! The desktop surely is colorful :-/

The irony... it would seem like??? palignr still??

Color is not quite present in the screen capture.

First press of command 3 also had as result that image data could not be saved...

I saw clearly that it mostly "misses color".

Just finished installing the VMWare tools... we'll see now if things are better...

Installing VMWare tools with custom parts did not help.

It would seem the problem is in the opemu (palignr or some other instruction responsable for doing some essential work!)

Ethernet in the VM required a small fix.

Add to Info.plist 0x10d38086 of Intel82574L.kext and remove IOPCISecondaryMatch.

Then ethernet works.

I put the desktop on auto-switch between images. image is now fine... (weird but hell)

I also now see the Safari bug mentioned.

It seems indeed like a misalignment of pixels.

I tried capturing a screen (took 5 attempts but hell).

Final result lacked color...

Installed WebKit patch, Safari seems stable.

Gonna test App Store now as final thing for today (need Xcode...)

App Store seems to work but very slowly...

Djeez

Then again... no packages are showing up....

Interesting case...

It does however show an update (which I'm applying through the Terminal)

Nope... no luck... no App Store...

Would seem the opemu needs further fixing...

I'm betting pallignr gives incorrect results..

I'm installing all and now App Store works!

It would seem I needed to login quickly this way.

Type gcc and select download Xcode.

Force it to download it and enter apple id.

Store works...

I noticed:

When I switched the VM back to windowed... desktop distorted again.

The problem is definitely somewhere in the blitting algorithms...

If we could pinpoint that function... bingo... we know what is wrong...

I'm betting there is an SSSE3 function in there and that's the one we need to examine...

user78405 · January 27, 2015

i am noticing lot activity on AMD side kernel lately, i think you all getting close of fixing yosemite kernel of making run faster on AMD FX but the processor is running fine on this kernel but the problem is due to GPU drivers are not running fast as should be like maverick last kernel was almost perfect speed in video and cpu, i understand this is very hard to code this correctly, everytime apple unleashed next os verison it gets worst for all of you, because without you, this can never work on AMD and correct specification Custom parts unlike LINUX and WIndows does very well..and still Windows 10 is something that apple couldn't counter this time around, this might be the best Windows version to reign in again...and its up to apple decision to counter that with more changes or yosemite might bust when that happen..

Hi AnV

TEST this

Replace 10.9.5 ImageIO no pixel bug

But Can not replace the file on 10.10

replace the file Must operate on other OS

path: /System/Library/Frameworks/ImageIO.framework

ImageIO-1095.zip

Andy Vandijck · January 27, 2015

Well chosen Terminal command can do it with the OS running.

Other thing:

I want to find the cause and fix it... would be more interesting as it most likely would fix all issues.

No more custom components then...

Stable good system ootb with only simple change of kernel.

I'm also thinking of switching the code back to opemu mark 3 as we now have SSEPlus!

Should be fine thus and support more and better instructions easily.

I would be able to add SSE4.1 and SSE4.2 with almost zero effort.

If one of those is used then, ... You guessed it ... it'll work...

I'm totally not worried about Windows 10...

In all accounts it is still Windows 7 with 8 extensions and a "stolen" "expose".

I'm totally not impressed with what they have done in the last few years.

If I had this amount of time I'd totally overhaul that OS...

They have thousands of Developers and this is what they accomplished? lol... what a laugh...

Those modifications could have been done in about 3 months by good skilled development engineers.

They're lazy and money hungry...

"You get free upgrade for the first year".

Yeah sure... I get full free OS forever with OS X...

Follow Apple then there too MS, oh yeah... right... no hardware to sell other than crappy tablets.

Too bad lol.

theconnactic · January 27, 2015

Folks, I'm impressed. When Mavericks finally went open source, it took a really long time to make it useable, and we should remember Mavericks was, in many aspects, incremental an update to Mountain Lion, while Yosemite had a lot of code rewritten from the roots. Luckily to us, Apple released the open source code in a period of weeks from the App Store release of 10.10, but we're even luckier to have quite a few skilled developers so committed to get everything running like it should, even for nine SSSE3 CPUs. Nice work, people: hats off to all of you.

I'm using AnV's BSA_YOS_R7D from here: #612

Both the installer and the OS proper work on my Athlon II X2 250, with no perceptible graphics glitches - but before I patched the appropriate AMD kexts for my HD5450, I was getting that hideously distorted multicoloured desktop background shown in AnV's post #630 's second thumbnail picture. It seems I also cannot drag and drop files using my mouse. Didn't try screenshots yet, but watched a lot of Netflix stuff without issues. Will test further, in a more systematic way,

All the best!

Hi AnV

I have a new found

On My machine OPEMU SSE3 dont works

SSSE3 working Only

My Processor AthlonII X2 270 is no SSSE3 instructions

Here is My Guess

Mac OS X Minimum Requirements are CPU Must Support MMX SSE SSE2 SSE3 SSSE3 instructions etc.

But Athlon No SSSE3. When Run APP have SSSE3 Opcode. So return "case T_INVALID_OPCODE" (in trap.c)

because Athlon dont know SSSE3. So Need SSSE3 Opcode Emulator.

Athlon has SSE3, know SSE3. So Not return "case T_INVALID_OPCODE”. dnot Run “SSE3_abc_run” code.

FX CPU Support SSSE3. May Not need SSE3/SSSE3 Opcode Emulator.

If FX CPU Not need SSE3/SSSE3 Opcode Emulator. can use the following code to test(opemu):

unsigned char opemu_ktrap(x86_saved_state_t *state){    x86_saved_state64_t *saved_state = saved_state64(state);    uint8_t *code_buffer = (uint8_t *)saved_state->isf.rip;    unsigned int bytes_skip = 0;    // rdmsr 0x0f 0x32    if((code_buffer[0]==0x0f) && (code_buffer[1]==0x32))    {        printf("[MSR] unknown location 0x%016llx\r\n", saved_state->rcx);        // best we can do is return 0;        saved_state->rdx = saved_state->rax = 0;        bytes_skip = 2;    }    if(!bytes_skip)    {        uint8_t *ripptr = (uint8_t *)&(saved_state->isf.rip);        printf("invalid kernel opcode (64-bit): ");        print_bytes(ripptr, 16);        /* Fall through to trap */        return 0;    }    return 1;}void opemu_utrap(x86_saved_state_t *state){    int longmode;    unsigned int bytes_skip = 0;    vm_offset_t addr;    if ((longmode = is_saved_state64(state)))    {        x86_saved_state64_t *saved_state = saved_state64(state);        uint8_t *code_buffer = (uint8_t*)saved_state->isf.rip;        addr = saved_state->isf.rip;        uint16_t opcode;        opcode = *(uint16_t *) addr;        x86_saved_state64_t *regs;        regs = saved_state64(state);        //sysenter 0x0f 0x34        if (opcode == 0x340f)        {            regs->isf.rip = regs->rdx;            regs->isf.rsp = regs->rcx;            if((signed int)regs->rax < 0)            {                //printf("mach call 64\n");                mach_call_munger64(state);            }            else            {                //printf("unix call 64\n");                unix_syscall64(state);            }            return;        }        //sysexit 0x0f 0x35        if (opcode == 0x350f)        {            regs->isf.rip = regs->rdx;            regs->isf.rsp = regs->rcx;            /*if (kernel_trap)            {                addr = regs->rcx;                return 0x7FFF;            } else { */            thread_exception_return();            //}            return;        }        if(!bytes_skip)        {            uint8_t *ripptr = (uint8_t *)&(regs->isf.rip);            printf("invalid user opcode 64: ");            print_bytes(ripptr, 16);            /* Fall through to trap */            return ;        }    }    else    {        x86_saved_state32_t *saved_state = saved_state32(state);        uint64_t op = saved_state->eip;        uint8_t *code_buffer = (uint8_t*)op;        addr = saved_state->eip;        uint16_t opcode;        opcode = *(uint16_t *) addr;        x86_saved_state32_t *regs;        regs = saved_state32(state);        //sysenter 0x0f 0x34        if (opcode == 0x340f)        {            regs->eip = regs->edx;            regs->uesp = regs->ecx;            if((signed int)regs->eax < 0)            {                mach_call_munger(state);            }            else            {                unix_syscall(state);            }            return;        }        //sysexit 0x0f 0x35        if (opcode == 0x350f)        {            regs->eip = regs->edx;            regs->uesp = regs->ecx;            thread_exception_return();            return;        }        if(!bytes_skip)        {            uint8_t *eipptr = (uint8_t *)&(regs->eip);            printf("invalid user opcode 32: ");            print_bytes(eipptr, 16);            /* Fall through to trap */            return ;        }    }    thread_exception_return();    /*** NOTREACHED ***/   // return ;//EMULATION_FAILED;}

Hi !

Why remove the code ? The FX processors automatically determine ssse3 enabled or disabled , and if you disable ssse3 - then don't work ssse3 emulation . If insert ssse3 emulation in opemu , and if in old cpus no have ssse3 , then goto to emu ssse3 !

We know what to fix in opemu ! But we must check what the problem instructions ...

Not disable or enable problem

You Can Download "Hopper Disassembler"

Download My attachment open with "Hopper Disassembler"

I write instructions OPCODE to this binary File

goto RIP 1466

What is opcode -> Operation code

a binary file contents is compiled machine code

App binary file Instructions opcode -> CPU

if cpu Unable to discern Instructions

goto case T_INVALID_OPCODE

You don’t do the test How do you know ?

If FX not run OPEMU SSSE3 EMU

On the FX machine You do the test Unable get any results

Kernel Panic after upgrading to 10.10.2

Last kernel BSA R7D not compatible with 10.10.2 ?

Kernel Panic after upgrading to 10.10.2

Last kernel BSA R7D not compatible with 10.10.2 ?

this should be a different cause. the source should work with the latest versions of Yosemite. Although I have not yet tested the current kernel

but the recent kernel running under 10.10.2 current build.

perhaps you need to use the System.kext from the kernel package.

repair disk permissions and refresh the cache, then start your system again.

FX CPU SSSE3 TEST

Other CPU Don’t Test

If your CPU support SSSE3 instructions

Help me test

it can into the desktop ?

if into desktop

Test Screen Capture & Image jpg Preview

I Want to know
FX is not Run SSSE3 Opcode EMU?
and SSSE3 OPCODE EMU is correct?

Please give me feedback

this opemu I dont add Any OPCode Emulator

Retain sysenter & sysexit only

Thank you for your test

In Safari? Yes

No bugs

In Safari? Yes

No bugs

Thank you...

now I know

If CPU is Supported SSSE3 & SSE4.1 & SSE4.2 & AVX1.0 No Need OPEMU instructions Emulator

and Not Run Function SSSE3_run

SSE3_abc_run is for SSE2 CPU or K8 early period CPU

On FX NO Bug

FX is Supported SSSE3 & SSE4.1 & SSE4.2 & AVX1.0

On Athlon or Phenom bugs

Maybe:

1.SSSE3 instructions Emulator Error

old opemu Function palignr is error

SSEPlus Unknown Maybe Fixed

2.Image error problem in ImageIO

Maybe ImageIO opcode Include SSE 4.1 or 4.2 or AVX1.0 instructions

So May be required SSE4.x or AVX1.0 opcode Emulator

With kernel-SSSE3-TEST.zip I get invalid user opcode 64 error..

Meowthra · January 28, 2015

With kernel-SSSE3-TEST.zip I get invalid user opcode 64 error..

This TEST AMD K10 FX CPU or APU SSSE3 CPU

K10 Phenom or Athlon Not Support
