Quadro P2000 Error 43 only when x16 primary slot ?!

dibg · March 30, 2021, 2:43pm

Wendell did open my eyes about pcie pass-through and here im trying to make it work.

My hardware is
R9 3900x
Msi x570 mpg gaming plus
gtx 1050ti
quadro p2000

Unfortunately the mb dosen’t have the option to select primary gpu and the second pcie slot is passing thought the chipset. no bifurcation.

I managed to pass a quadro P2000 (on the x4 chipset pcie slot) into the win10 vm (manjaro host) by using this scripts : GitHub - pavolelsig/passthrough_helper_manjaro
It works but looking glass at 1440p bottleneck by the 4GB/s bandwidth (around 30fps)

So i decided to switch the 1050ti from primary to secodary and use the p2000 at full x16.
2 days later still din’t manage to do it so im reaching out for help.

The state im now is that after dumped the p2000 vbios from windows* and passed into the vm i can see image in the uefi tianocore and after the booting of windows starts no more updates in the extrnal display only in the qxl kvm based.

after i edit them with a hex editor to remove the nvidia header used for flasing.

In the window manager i get error 43. I thougth to hide the kvm allthought i din’t had to hided when i had the p2000 in the second slot still nothing.

im out of ideas at this point.

this is my logs of the pcie:

Doubtful the x4 is bottlenecking you, I ran a hd 7950 off a 1x 2.0 bus with no difference vs 16x 3.0

Your p2000 will need much less bandwidth than say a 1080

Nvidia now supports resizable bar, so if your mobo and CPU supports that with a bios update that will help with code 43

It probably has more to do with going through the chipset and maybe a plx chip than the amount of lanes, it takes a latency hit

i discuss this today on the looking glass discord, It’s actually the case tha the 4Gb/s bandwidth is not enough for 1440p.
original message:

for 4xpcie3.0 you get around 4GB/s , my max frame buffer for 1440p is 29MB so for 60 fps → 60 * (29* 2) = 3480 MB/S so near maxing out the pcie bus (i did the calcultation with 2 frames copied im not sure if that’s correct, otherwise is half that) and ofcourse the gpu needs bandwidth for the games as well so … i guess i will still have to figure out a way to use the quadro in the top slot

i just installed the 465 driver into the vm no difference, i pressure the code 43 this time it means actual problem

GigaBusterEXE · March 30, 2021, 3:52pm

Have you enabled resizable bar in bios
Looks like you need a updated Vbios as well

dibg · March 30, 2021, 4:25pm

This is not the problem and this is for the 3000 series only, i only needed to see if the error 43 is coming from the driver lock or something is wrong.

The problem is probably in something i do. This should work with a quadro with out error 43 . Maybe something i posted here is not correct.

GigaBusterEXE · March 30, 2021, 4:58pm

They’re back porting it all the way back to kepler, so you won’t get code 43 on your 1050ti is why I was posting
No idea on the quadro

update:
i hided the kvm with :

  <features>
    <acpi/>
    <apic/>
    <hyperv>
      <vendor_id state="on" value="whatever"/>
    </hyperv>
    <kvm>
      <hidden state="on"/>
    </kvm>
    <vmport state="off"/>
    <ioapic driver="kvm"/>
  </features>

allocate the audio and video of the gpu in the same bus

<address type="pci" domain="0x0000" bus="0x2d" slot="0x00" function="0x0" multifunction="on"/>
..
..
.. 
<address type="pci" domain="0x0000" bus="0x2d" slot="0x00" function="0x1"/>

removed the qxl video adapter

and it’s now the quadro displaying image thought the screen that’s connected but still it says (error 43).

dibg · March 30, 2021, 7:30pm

update:
I put the computer to sleep for a couple minutes and tried to wake it up to see if running the vm after sleep makes any difference. Nope.

I put the computer to sleep for a couple minutes and then removed the card from the slot for 1 minute and the put it back wake and run the vm to see if will makes any difference. Nope.
Dumping the vbios under linux gived me the same hash before pulling out and after.

edit actual it seems that it dosen’t read the gpu since i complete removed it and still give me the same dump

edit 2
i started the pc with out the quadro and put it when it finish booting in sleep mode. it not show up in the pcie devices so this path lead nowhere.

dibg · April 6, 2021, 5:10pm

Still nothing. Im sure we have the right talent in this forum to solve this problem. Any suggestions ?

Edit: Sorry, I just realised I necro’d this thread, another post was made and deleted which brought this to the surface.

How is this going to help things? Now your other GPU is bandwidth limited. Both GPUs need to have enough bandwidth, not just one.

Looking Glass is copying full frames of data across the bus, it’s not your typical desktop/gaming usage/bandwidth.

Error 43 is just a general failure to initialise error, it can mean many things. The most common cause is the nvidia driver detecting you’re in a VM, but it’s also known to happen if you give the VM the GPU bios which is UEFI and have not used the romparser and dd to pull out the part you need.

As for newer drivers being VM friendly, it’s only partially true. While yes they will no longer code 43 due to being in a VM, they still cripple some GPU features, such as custom resolutions which is quite important for Looking Glass users that use a HDMI dummy plug that doesn’t report the resoltuion/refresh rate they wish to use.
