Cant Turn off Kernel DMA protection for thunderbolt 4 ?
Post before that dma give blue screen and i open up everyting but DMA Kernel Protection is always ON whatever i do? I choose inactivate Kernel DMA security but still always says that its ON when i check in msinfo.
Its TB4 and cant find any info about it to get the DMA working on this laptop with the OWC encloser and most get that DMA security of somehow? Heard its not possible to use DMA on TB4 now is that the case really?
i see pictures that you have working dma in your laptop, how you do it? can you provide devices names pls
BIOS dont have that features its a Lenovo Legion 5 pro. Thanks again
I'm really sorry, but I don't have a Lenovo Legion 5 pro system to test against.
You'd have to find some way to disable DMA and Kernel DMA protection in BIOS settings about VT-d, AMD-Vi, IOMMU, Device Guard, Kernel DMA Protection, ThunderBolt Security Level etc. and in OS settings. Similar to what I mentioned before.
Also please understand that this is an open source project and not many support it. I can't go on and buying very specific hardware from my own money to test things out just so that other hardware vendors may profit more from what I mostly give away for free.
If you don't find any settings on your Lenovo model please contact the one selling you the hardware. They may have some more tips and tricks for this.
