ARM support is coming

There are lots of requests to support ARm systems.  I am going to modify RU for ARM UEFI shell.

RU 5.34.0426 BETA

This is a very minor change from previous 0425 build.

NOTE: Absolutely not tested at all, please use it with cautions!

• Fix RU stops responding for a long time (looks like hang) while starting up
  
• "Probably" fix the BAR size issue

Download it from github

p.s. blogger doesn't seem to be a good place for RU release notes, plan to move to somewhere else??

RU 5.33.0425 BETA

BUG: This version has a bug that makes it look like hang.  Do not download this version.

 

This is a minor bug fix version for QEMU as reported by one of RU users.  As always, nothing has been fully tested.

• Fixed ASSERT on Pool.c in QEMU

• Detect undefined MSRs for other CPUs, not just Intel's

RU 5.32.0423 BETA

 This version supports accessing PCI segments.

• RU.EFI: Support PCI segments
• By default it still accesses the segment 0 by 0xCF8 / 0xCFC, you can use "/S10" command line argument to force RU.EFI to call PciIo protocol
  
• PCI segment > 0: It calls PciIo protocol
• F6 list format is displayed as Segment/Bus:Device:Function (00/00:00:00)
  
• Shift-F2 save memory as binary supports all memory read bus_type: PCIE, Variables, AHCI, USB, ACPI, SMBIOS
• Fix Shift-F2 saves memory binary always saved the wrong size
• Fix ALT-= UEFI variables hangs with big-size variable
• Fix data saved by "RU /D SMBIOS " is wrong
• Fix a bug of ALT-3 detecting SMSC SIO

RU 5.31.0410 BETA

WARNING: Not tested at all (as usual 😆) 

This is a fixed version from 5.30.0408 which has string operation problem causing errors of display bits, detecting SIO, accessing UEFI variable, etc.

RU 5.30.0408 BETA

WARNING: NOT TESTED AT ALL!

*** 2022/05/13 update ***

Sadly this version contained a bug that SIO detection is failed and some string display problems.  

I suggest to skip this version and wait for the next one.

Just some minor changes.  No new features.

• Fix possible SMBUS read failed
• Fix "ru /d VARS" not working
• Fix "ru /d smbios" hang
  
• Fix SMBUS manual selection not working
• Add Ctrl-Home and Ctrl-End to navigate to the first and last page of all registers
• Fix ALT-F1 Mass Storage not reading LBA correctly
• Fix Ctrl-Home/End not working for CPU MSR

Errors for writing UEFI variables

Recently I got lots of questions for writing UEFI variables (ALT =), I believe it is because users wants to unlock the capability of your system.  And some blogs even mentioned how to do it with RU.

Due to the security reason, recent UEFI system firmware will not allow you to modify sensitive settings (variables).  And there is no way to change it unless you can update the SPI by a physical  programmer.

Here are what error numbers mean (UEFI spec) after you pressed CTRL-W.
