The difference for example at address 0x3A

Slice, the difference introduced by rev 3444 is that there are some instructions in the code

leal MemoryMap, %edi

leal MemoryMap, %eax

movl %edi, MemoryMapSize # Save the size of the memory map

leal MemoryMapSize(%ebx), %edx # Physical base address of the memory map

 

That refer to MemoryMap and MemoryMapSize, both of which are located AFTER the IDT. Since the IDT got shortened, those memory references moved. That is why you see a change at address 0x3A and 3 others. Those are ok.

 

Please try padding with an extra entry like I suggested. The reason I said this, is that there was padding with an extra entry in CpuInterrupt.S, and I commented it out, because I didn't think it's needed.

But it could be that on some processors, the IDT needs to be padded.

 

BTW, the character 5 is showed on the screen in real mode before GDTR and IDTR are loaded, so why would IDT make a difference??

 

PS (disassemble with ndisasm -b 16.... is best. You can use -e to skip and -o to set origin)

@Zenith432 I wanted to send you a PM, but it seems like you have disabled receiving such... Sorry for OT:

Did you see that Laszlo replied to your patch mail with a suggested splitting of commits? Hope you are still going to get it merged.

 

Regards,

DF.

Clover3496.

 

I compiled clover 3496 (-t XCLANG,-t XCODE5,-t GCC53),using initially buildExtras.sh in the following systems - OS_X-10.9.5_Xcode6.2, OS_X-10.10.5_Xcode6.4,OS_X-10.11.4_Xcode7.3.

Boot the system  using boot6, boot7, UEFI succeeds.
 
 

 

I once again checked all.

Excuse me! I made a mistake.There are problems with Boot6 when compiling to OSX10.9.5 (Xcode4.6.2) and 10.10.5 (Xcode6.4) if you use the ToolChain XCODE5 . Everything else works.

The problem could be with size of boot6.
In rev 3447 I added script code to use --std-ebda on-the-fly if the code does not fit in --low-ebda.
The --std-ebda size is until 0x96000.  However, the stage 1 bootloader does not check for ebda-overrun when loading boot6/boot7.

If the ebda on a system extends down under 0x96000, it is corrupted without early detection.

So check the size of the bootfile.  boot7 is smaller because of fewer Dxe.

 

OK, thanks. It may explain why the issue shown on some processor not for all.
I will test  and invite other users to test if this padding will help.


droples, chris1111, please post exact size of your boot6 that doesn't work.

Then please try this....

build with same compiler, but use --genpage option to ./ebuild.sh.  Note size of boot6 with --genpage, then check if it succeeds booting and if you encounter problems.

Ok this is the boot6

Now test --genpage

Is this normal its bif init T  :) not 6

But same result stuck at the same point

EDIT**

this is strange on El Capitan10.11.5 with the same compiler but Xcode 7.3  everything is perfect?

chris1111, 482816 = 471.5K is the size of --std-ebda.  But if --genpage ('T') does not give error message then ebda-overrun is not the cause of the hang.  It's something else.

What do you mean same compiler and Xcode 7.3?  They're both clang, but newer clang.  Can you upload the non-working boot6? I'll try to see if it hangs on my system too.

Xcode 7.3

I'm having several of these lines:

Is that Ok?

chris1111, droples: Do you have the latest Patches_from_EDK2 up-to-date?  Building with Xcode < 7.3 requires at least

MdePkg/Include/Base.h

MdePkg/Library/UefiDevicePathLib/DevicePathToText.c

 

to be patched.  Otherwise, it'll fail for sure.

 

The problem is not ebda-overrun.

I'll try the bootfiles you uploaded later.

I tried the uploaded boot files.
The one from post #686 hangs on blank screen.
The one from post #689 Xcode62 hangs on blank screen.
The one from post *689 Xcode73 works.
 
So it's a different problem.  Since the Xcode 7.3 works, I tend to think it's the VA_LIST problem again.  Can you help me check if this is it as follows:
modify edk2/MdePkg/Include/Base.h like this

don't save it. Just modify it to make a build. Then build boot6 with xcode 7.3, try and see it hangs or gets to the menu. If it gets to the menu, try starting the EFI shell and see if it hangs. Thanks.

 

Update: never mind, I tried it myself with xcode 7.3 - and the boot works ok.  It's some other problem.

Yes I have the patch_from_edk2 .

 

Everything working perfect inside

El Capitan 10.11.5 the problem is only inside Yosemite 10.10.5

I'll download Xcode 7.2 and try reproduce the problem. It's not high priority to support older build environments though.

BTW, is the hang only with boot6? Does boot7 work with older compiler? (boot7 is -mc --no-usb)
