EfiPy_r0.1.4(24622) release

Release Note
This is personal project (author: https://www.facebook.com/wu.max.39).
EfiPy_r0.1.4(24622) is released today for sync for UDK 2017 rev 24622.

What is the next of EfiPy:

1. Easy memory operation in UEFI shell with Python. (Status: in progress)
Example:
1.1. MSR operation:
print "msr[0x1B][8]:    0x%016X" % msr[0x1B][8]
print "msr[0xFE]:       0x%016X" % msr[0xFE]
print "msr[0xFE][7:0]:  0x%016X" % msr[0xFE][7:0]
print "msr[0xFE][0x08]: 0x%016X" % msr[0xFE][0x08]
print "msr[0xFE][0x0A]: 0x%016X" % msr[0xFE][0x0A]
1.2 Memory operation:
print " Mem8[0x3FF39018]: 0x%02X"  % Mem8[0x3FF39018]
print "Mem16[0x3FF39018]: 0x%04X"  % Mem16[0x3FF39018]
print "Mem32[0x3FF39018]: 0x%08X"  % Mem32[0x3FF39018]
print "Mem64[0x3FF39018]: 0x%016X" % Mem64[0x3FF39018]
1.3 IO port
print "Io8[0x71][0:7] & 0x86:   0x%02X" % (Io8[0x71][0:7] & 0x86)
print "Io8[0x71] & 0x86:        0x%02X" % (Io8[0x71]      & 0x86)
print "Io8[0x71][0:7] | 0x86:   0x%02X" % (Io8[0x71][0:7] | 0x86)
print "Io8[0x71][7:0] | 0x86:   0x%02X" % (Io8[0x71][7:0] | 0x86)
1.4 CPUID
print "CPUID(0x01).Regs.EAX.Uint32: 0x%08X" % CPUID(0x01).Regs.EAX.Uint32
print "CPUID(0x01).EAX (Hex): 0x%08X" %       CPUID(0x01).EAX
print "CPUID(0x01).EAX (Bin): %s" %           bin(CPUID(0x01).EAX)
print "===> EAX.SteppingId: [Bits 3:0] Stepping ID"
print "CPUID(0x01).EAX[3:0]: 0x%08X" %        CPUID(0x01).EAX[3:0]
print "CPUID(0x01).EAX.SteppingId: 0x%03X" % CPUID(0x01).EAX.SteppingId
1.5 others...

2. Py2Efi (Status: in progress)
What is Py2Efi?
Capsule program running in EFI shell which packs python libraries into single .efi file.
This capsuled .efi file is a standalone EFI program which makes itself run in another platform without any other python programs.

    Hi Max,

    I found your project will fail on EDK2 Nt32 enviroment. below is my fix.

    Hi Bin.lain,

    Thanks for your feedback.
    As current EfiPy status, it is at its early stage and developed on X64 ABI.
    you did fix error if EfiPy is ported for IA32 ABI.

    EfiPy exists EFIPY_MDE_CPU_TYPE constants in Python _EfiPy module (EfiPyMain.c) for ABI identification in the future.
    For multiple ABIs support, EfiPy will import ABI dependence module by EFIPY_MDE_CPU_TYPE. The module will include UINTN, INTN, ENUM, at least.

      Hi Bin.lain,

      As your comment. It has release(EfiPy_r0.1.8(24622)) including other ISAs.
      Note, EfiPy does not yet support the other ISAs.

      Thanks
      Max
