Re: Tianocore hangs on boot

["Ma, Maurice" <maurice.ma@intel.com>]

Hi,  Janne,

By looking into your log, it seems to be some memory map related issue.  The CorebootPayloadPkg failed to find the proper usable low memory.

I noticed an entry in your coreboot memory map as below:
2. 00000000000C0000 - 000000003FFAFFFF [01]

And this entry was not handled properly by the CbSupportPei module.   This module currently assumes an memory map type 1 entry with (base >= 1MB) exists.  But in your case it combines with legacy C/D/E/F segments.    I think we should fix this in CbSupportPei module.

Could you please try the following change and let me know the result?  

--- a/CorebootModulePkg/CbSupportPei/CbSupportPei.c
+++ b/CorebootModulePkg/CbSupportPei/CbSupportPei.c
@@ -170,6 +170,12 @@ CbMemInfoCallback (
              EFI_RESOURCE_ATTRIBUTE_WRITE_BACK_CACHEABLE;

   MemInfo = (CB_MEM_INFO *)Param;
+
+  if ((Base  < 0x100000) && ((Base + Size) > 0x100000)) {
+         Size -= (0x100000 - Base);
+         Base  = 0x100000;
+  }
+
   if (Base >= 0x100000) {
     if (Type == CB_MEM_RAM) {
       if (Base < 0x100000000ULL) {

Thanks
Maurice

Subject: [edk2] Tianocore hangs on boot

Hello everyone,

I' currently trying to get CorebootPayloadPkg to work on QEMU.
I turned on Tianocore debugging (see my previous message) and tried to run a coreboot with UEFIPAYLOAD.fd as ELF executable payload which resulted in the VM hanging.
I also tried to add it as a payload of the "Tianocore" type (which seemed to be more logical but is not what the documentation says), but I got the same result.

My QEMU command line: qemu-system-x86_64 -M pc -bios build/coreboot.rom -serial stdio -m 1G -vga qxl

It just keeps hanging here.

I'm sorry for just dumping the log here, but I really don't understand what the problem is and hope anybody here knows something so I can boot Tianocore with Coreboot.

Thanks in advance.
