    [SOLVED] PVE 8.2 zfs now grub? and rescue still not working :(

    I recently installed PVE 8.2 from the new iso available. And as per usual I used a zfs mirror to install on. However this time around the boot loader seems to be grub rather than systemd boot. Last I was aware of is that when using zfs the installer defaults to systemd boot and not grub...

    AMD iGPU passthrough won't work

    something like this is what you want to see on the host when you run dmesg | grep amdgpu [ 5.084765] amdgpu 0000:06:00.0: enabling device (0006 -> 0007) [ 5.087448] amdgpu 0000:06:00.0: amdgpu: Fetched VBIOS from VFCT [ 5.087458] amdgpu: ATOM BIOS: 113-CEZANNE-017 ATOM BIOS: ***** And...

    AMD iGPU passthrough won't work

    none of it during your reinstall and getting the amdgpu driver to load correctly on the host. once you have that up and running then it becomes time to think about passing it through

    AMD iGPU passthrough won't work

    in your case it is best to start over. as disabling IOMMU is not required in order to not blacklist or load vfio drivers. So better use a clean slate and document well what you are doing or use a tutorial from proxmox it self like https://pve.proxmox.com/wiki/PCI(e)_Passthrough

    I can't make that call for you :) I for one am starting over again pretty soon. But I do not know how much you have already tweaked your system.

    AMD iGPU passthrough won't work

    I am unaware of any tutorial you have used. but it does not matter. just undo anything you did and see if you can get the amdgpu driver to load normally.

    AMD iGPU passthrough won't work

    dont run any vm that has that igpu passed through. remove any blacklists remove the vfio-driver loading for the igpu. just like in the tutorials but then in reverse. and then show the output of dmesg | grep amdgpu you will find the name of the vbios file being used if the motherboard supplies...

    AMD iGPU passthrough won't work

    My advice would be is to first not blacklist it and not pass it through and also not load vfio drivers at any stage. let your host system figure out which vbios file to use. or do you get greeted with an error message that a VBIOS file could not be found in your host's dmesg? I have had that...

    [SOLVED] rescue boot change kernel cmdline

    thank you leesteken. it did hint me more into the right direction. I was able to use the proxmox iso debug installer which I exited to enter a shell then I was able to update the /etc/kernel/cmdline using the steps found below...

    [SOLVED] rescue boot change kernel cmdline

    I run the latest proxmox with root on zfs I locked myself out of the system by having added too many kernel cmdline parameters (/etc/kernel/cmdline) related to the disabling of the display. So I tried using the rescue boot option on the most recent pve iso but it errors out stating it can not...

    AMD iGPU passthrough won't work

    I see you are still blacklisting the amdgpu driver? or perhaps not blacklisting it but having the vfio-pci being used for your igpu instead. the idea is to have it load normally to be able to see in the dmesg which BIOS rom file is loaded as supplied by the firmware on the motherboard. But...

    AMD iGPU passthrough won't work

    ahh well you know the age old saying. give a man enough to drink and he will start reading up out of sheer boredom :) So in order to work from the top down you indeed need to revert a few steps back in order for me to be able to help out. If things never worked on the host then I am not sure I...

    AMD iGPU passthrough won't work

    ok. it looks like you are missing a lot of command line parameters but that is of later concern. also I did not see the amd driver being correctly loaded. So please make sure they are on the host by disabling blacklisting and any VM that might want to use it. then on the host (no VM just yet...

    AMD iGPU passthrough won't work

    you see, rather than focusing on the Vm it self I would like to tackle this potential problem from the top down. For example I have tried many configurations for VMs and I like the linux way of booting in where I can see things go right or wrong. Now if we get a linux VM up and running then we...

    what specific tutorial are you referring to? Please remember I am just soo busy that sometimes I have time to write a long wided answer like I do now. But reading up on long threads has never been my strong point if I enter as an advice giver rather than the needer of advice. So. Please show...

    AMD iGPU passthrough won't work

    I will still try and help. what specific hurdle are you facing at the moment? If you can be forthcoming then that saves me from reading up on a thread of which I have read sooooo many already. some of them end up in success while most just end up abandoned after a while.

    AMD iGPU passthrough won't work

    it can never be on the proxmox side as proxmox is just a layer on top of debian which is just yet another lay on linux. Please be more specific. Also ubuntu also failed for me while I was at 90% of reaching my goal. So once again if you are serious about this issue then please be serious...
