RU 5.40.0433 Beta for ARM support

Finally I fixed several GCC build errors and do the test inside QEMU and it seems to be working. So I decided to release it during a day off for incoming Typhoon.

This version is mainly forAARCH64 

BUT!  It was ONLY TESTED in QEMU

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

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.

0x00000000 EFI_SUCCESS               

0x00000001 EFI_LOAD_ERROR

RU5.28.0397 BETA

Updated: 0396 build was removed and here is the new update 0397 build, thanks to @martin reporting the problem.

This version fixed mainly SIO and keyboard not working properly.  But I just did some very limited tests and some are not even tested.  Please note that It's not guaranteed that it works as expected.

Fix

• Fix RU can't remember SIO LDN
  
• Possibly fix the problem of reading keyboard input
• Fix the problem of showing many non-existed SIOs
• Possibly fix RU /L for SMBUS not working
  

RU /Sxx (Safe mode)

        xx stands for bits, for examples: RU /S4 means to skip SIO detection

• BIT0=1: Read MTRR only for ALT-8 CPU
  
• BIT1=1: Display readings from keyboard
  
• BIT2=1: Skip detecting SIO
• BIT3=1: Skip initializing text mode

RU 5.27.0388 BETA

This version mainly add a test switch in command line for debugging keyboard combination problems.

Also it fixes the problem of "Save all PCI devices" resulting wrong data saved when 32-bit width is selected as reported by an user.

NOTE: It has not been tested, any wrong readings can be happened.

Command line "/S"

• RU /S2
• It shows RU key codes on the top of the screen when a key is pressed
  
• RU /S1
• It will only access CPU MTRRs, not all MSRs.  This is to avoid the hang while reading full set of MSRs

RU 5.26.0386 BETA

This version only fixes dome problem.  The main change is that RU takes too much time on some system scanning PCI devices.

NOTE: I didn't test it at all so it could be buggy.

• Fix PCI hangs with PCI device base code 0xa.
• Add IDE/AHCI prefix to ALT-5(HDD detection) device name
• Fix "RU /L" loading file error
• Fix SMBIOS data not restored after re-enter RU
• SIO: Fix it detected lots of non-existed SIOs on some systems
• Fix ACPI table displayed wrong MCFG/FPDT/DMAR/DBG2 details
• Add new ACPI UEFI table
• Previously RU scan all PCI functions unconditionally for better compatibility but it takes time. It is changed to scan PCI functions only if it's multi-function
  
• Use Shift-F6  for scanning PCI functions unconditionally.
• Fix SPD ALT-0 read failed (error: not existed)

Known issues: 

•  All characters typed will be converted to lower cases

RU 5.25.0379 Beta

This release was requested by an user to support detecting multiple SIO.  Again, not all functions are tested.

• Support Exar SIO detection
• Support for detecting up to 6 SIOs at the same time (NOT TESTED)
• Fix ACPI (ALT-6) hangs on Intel Menlow platform
• Ctrl-S is replaced by Ctrl-U to toggle sound
• Fix some strings displaying problems

Tutorial: Type to find string

On any screen like below, you can just type any key to start the "find" dialog, so you don't need to browse the name one by one.  This has been done for years but I doubt anyone knows that.

Below is an example on variable (ALT-=) selection screen:

RU 5.24.0370 Beta

Features

• List all available MSRs from #0 - #1000 even for those MSRs not recorded in RU name database

• Add page number displayed for CPU MSR
• SIO: Add Fintek vendor IDs for auto-detection (NOT-TESTED)
• SIO: Fix auto-detection is not working (tested only on one system)
• Command line mode ` : All functions key are allowed (not sure is there will be any side effects)
• Command line mode ` : The line will be changed to color red indicating it is in command line mode
• Fix ACPI ALT-6 page number are displayed incorrectly after page #0xFF
• UEFI configuration table from System Info CTRL-I can be browsed more than one page
• Some minor UI changes

RU 5.22.0354 Beta

This is a bugs fixed version release.  There are some long-existed problems caused system hung but just few reported to me.  I am wondering why just few people notice that...
However it is still not tested and I always created some other bugs XD.

Bugs fixed - Multiple hangs fixed!

• Fix RU.EFI hangs while reading MSR hangs in Kabylake platform
• Fix RU.EFI hangs running on Comet Lake U platform since 5.11.0196
• Fix RU.EFI hangs in a system without GOP
• Fix writing to CPU MSRs is not working
• Fix CTRL-G not working, it sometimes go to address 0
• Fix RU.EFI Ctrl-F, Ctrl-D waits for keys to continue

 Minor changes

• ALT-8 CPU MSR will first select which CPU to look at, so as ALT-M
• Display Number of CPUs in System Info [CPU] section.
• Add /S to command line as SAFE mode

Known issue: ALT-8 Can only read MTRRs...  I created another bug XD, fixed and will be released soon.

Reading EC controllers?

It's done!  Check it out.
