Hi, Im new to the forum but was very interested in this how-to, thank you for sharing! I've followed the instructions, but I'm running into issues with the passthrough itself. When I start the openwrt VM I get the following:
If I remove the passthru then openwrt starts, so it seems to be an issue with the passthrough. I set and enabled all of the tunables and have set the devctl to use ppt0 as described. I have tried a few formats of passthrough, some sites I've seen to use 2/0/0=7:0, whereas some show 2/0/0=07.0 but both give me the same status 4 error.
Another user had the same status 4 error, and vmm_load = "YES" resolved it for them but I still have the same problem in my case. Are there any other tricks or tips for getting the wifi device passthrough to work? The specific device I am trying to pass to openwrt is 'QCA986x/988x 802.11ac Wireless Network Adapter'.
I also enabled debug and have these other logs:
Would appreciate any and all feedback, thank you!
