Intermittent failures with MemProcFs #3

Closed KernelKrusha closed 10 months ago

KernelKrusha commented 1 year ago

Using MemProcFS, the latest version of the firmware on Intel i9-10850k (Z490) results in intermittent failures.

Log output: Device Info: FPGA: Bad PCIe TLP received! Should not happen!

Other than this, it seems to be working perfectly.

Alright. I'm quite sure this multiplexer could cause them: https://github.com/ekknod/pcileech-wifi/blob/main/src/pcileech_pcie_tlp_a7.sv#L111

I did freestyle implement it without further testing. I check in future if i can improve it.

Seem to be having an issue where the DMA card is unable to process any read/write operations for a few minutes at random intervals. Thought maybe it was something wrong with my setup or code but I flashed the original PCILeech firmware and I did not encounter this issue.

Same for me. Dma stop work for a few seconds after a certain number of seconds. I think it's because of the Qualcomm wireless card driver. It has a Wi-Fi update interval setting.

That's accurate. Multiplexer prefers signal from PCIe over FT601 currently.

So is there any better way to solve this problem?

ekknod commented 1 year ago

is this actually problem? it prefers device driver requests over FT601 on purpose.

Yeah, it made the firmware unusable for me. My read operations were taking way too long at certain times.

ironman97 commented 1 year ago

This is a great project, and it would be even better if it could continue to work.

About Device Info: FPGA: Bad PCIe TLP received! Should not happen!

I found that only the Intel (13900KS+Z790) platform will display these errors, and AMD (5950X+X570) seems to be work fine.

大约 Device Info: FPGA: Bad PCIe TLP received! Should not happen!

我发现只有Intel（13900KS+Z790）平台才会显示这些错误，而AMD（5950X+X570）似乎工作正常。

5900X+B550 This problem still occurs

Z690 update bios nice job.

ekknod commented 10 months ago

Core is now updated Version. 4.13. Issue should be now fixed. Disable WIFI from system tray in case you have TLP misses.
