VmmWinInit_TryIntialize: Initializtion Failed #139

Closed Nigesi closed 4 years ago

Nigesi commented 4 years ago

Hey Ulf, much appreciate your work, thanks so much.

I try to solve this issue, but i have no clue what I'm doing wrong. I update to the version 4.6 and still got that issue

The secruity options in my bios are disabled and I'm working on a Ryzen 1600x.

Any clue?

Test

Yes, bitstream changes to the fpga isn't enough to fix it completely on AMD. I also have to make a small change to the MemProcFS.

You can't read the whole memory block of lower 1MB in VmmWinInit_DTB_FindValidate(); it will have to be changed to it only read between addresses in the below image. Note that is the new code that will be published; if making changes you'll have to adjust it to the older reading function.

I'm publish this as soon as I have a bunch of other features ready; aiming for August/September some time.

Please try the release just released. This should now be fixed. For best stability I would suggest starting MemProcFS with: MemProcFS.exe -device fpga -memmap auto on your Ryzen system. Note that I have only tested it on a 3900X but I believe other Ryzens should behave the same.

Since this should now be fixed I'm closing the issue. If you should still experience any issues please let me know and re-open the issue.
