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

Hi James, I use this version to check, PCI segments is correct, can see CPU1's pci device,
but I check CPU1's pci device serr function found can't be trigger, CPU0 is can trigger, can you help to check this problem? thanks.
trigger PCI SERR command: FF at 07 and 01 at 43.
Hi @Whyte,
Is it working if you use mm or pci commands in UEFI shell?
Hi James
I'm not sure waht to do, did you mean at UEFI shell and use pci command to set FF at 07 and 01 at 43? thanks~
Hi James
I use PCI to found my pci scsi card:
PCI Segment 01 Bus 41 Device 04 Func 00
And I use command: pci 41 04 00 -s 01 -i
can get configuration space:
PCI Segment 01 Bus 41 Device 04 Func 00 [EFI 0141040000]

And then I check mm to set: mm 014104000 -PCIE
and clcik enter to 01410400043 and set 01 then system will hang and BMC can get SERR log, so looks like can work at EFI shell, can you help to check tool? thanks!
Hi @Whyte
I will check why writing is not working.
But it will take some time.
Does hello.ru support Legacy mode?
Yes RU.EXE is an legacy mode DOS application.
Hi James,
We met one problem that some MSRs may not be supported in some CPUs.
And that causes the general-protection Exception (13).
Is it possible to add some exception handling for fault-tolerance?
Thank you
Bin
Hi Bin,
GP fault exception was already added. Can you please try "RU /s1"? It just read standard MSRs. If it does not hang then it means the exception handler is not working.
Hi James,
最近在玩Ovmf, X64 發現ru.efi在rev 370以後會assert
[Security] 3rd party image[0] can be loaded after EndOfDxe: PciRoot(0x0)/Pci(0x1,0x1)/Ata(Primary,Master,0x0)/HD(1,MBR,0xBE1AFDFA,0x3F,0xFBFC1)/\RU423.efi.

Rev. 363是好的
我有把qemu開到4G memory了 也是一樣assert在這裡~
不曉得這會是什麼問題?
edk2使用的是edk2-stable202108
Preparation:
1. Build OvmfPkg with EDK2 codebase
build -a X64 -p OvmfPkg/OvmfPkgx64.dsc
Get Ovmf.fd after build successfully.
2. Install qemu(qemu-w64-setup-20230424.exe <- the version i use).
https://qemu.weilnetz.de/w64/
Execution:
1. Use qemu to run ovmf.fd, with bios log saved and emulate a virtual disk
we can put .efi files in the virtual disk to run it once it boots into shell.
here, I put everything include ovmf.fd and efi files in D:\temp, set "C:\Program Files\qemu" to PATH in windows.
run below command:
D:\temp\qemu -bios ovmf.FD -debugcon file:debug.log -global isa-debugcon.iobase=0x402 -hda fat:rw:d:\temp\ -m 4G
The bios serial log debug.log will be saved in the same directory(the ovmfpkg is default built with DEBUG MODE).
sorry, command should be
D:\temp\qemu-system-x86_64.exe-bios ovmf.FD -debugcon file:debug.log -global isa-debugcon.iobase=0x402 -hda fat:rw:d:\temp\ -m 4G
because I copy qemu-system-x86_64.exe as qemu.exe to make the command easier.
Hi YouGotIt,
I think RU have accessed directly to some H/W that caused the problem. Will use the OVMF to debug. Thanks for the details.
Hi YouGotIt,
I got the assert problem fixed, thanks for reporting this bug.
Thank you, James!!
