Prem,
I've not run the emulator on Windows in a very very long time. But lets take a
look at your error message.
/Volumes/Case/UDK2018(vUDK2018)>git grep "Could not allocate
PeiServicesTablePage"
EmulatorPkg/Unix/Host/Host.c:508: printf ("MapFd0(): Could not allocate
PeiServicesTablePage @ %lx\n", (long unsigned int)EmuMagicPage);
That seems to point to PcdPeiServicesTablePage
/Volumes/Case/UDK2018(vUDK2018)>git grep PcdPeiServicesTablePage -- *.dec
EmulatorPkg/EmulatorPkg.dec:73:
gEmulatorPkgTokenSpaceGuid.PcdPeiServicesTablePage|0x1003000000|UINT64|0x0000101b
Which has a default value of 0x1003000000. But since you built for IA32 it gets
truncated to 0x03000000
Do you need 32-bit IA32? Can do a 64-bit build and use X64. Something like:
build -p EmulatorPkg\EmulatorPkg.dsc -t VS2015x86 -D WIN_SEC_BUILD -a X64 -m
EmulatorPkg/Win/Host/WinHost.inf
It looks like that is hard coded address that needs to get allocated in the
emulator, and in your case that allocation is failing.
Thanks,
Andrew Fish
PS I'm not sure the printf is correct: printf ("MapFd0(): Could not
allocate PeiServicesTablePage @ %lx\n", (long unsigned int)EmuMagicPage);
Given the width of long is different on different platforms. UINT64 uses long
long to make sure things are 64-bits. Not to mention EmuMagicPage is a pointer,
not an long unsigned int.
