Windows 11: How to remove or disable ACPI to pass-thru my GPU inside a Windows VM under bhyve

[ziomario]

Hello.

What I would like to understand is why,when I try to pass my RTX 2080 ti from FreeBSD to Windows 11,it won't do it,causing the error 12. It says that it generates a resource conflict and requires additional installation).

I'm trying to debug the error. Below you see the IOMMU group of my Nvidia Geforce RTX 2080 ti passed in a Windows 11 / bhyve VM and of Windows 11 installed physically. I'm not able to understand if there are inconsistencies.

Now,inside it I still see the error 12 :

The device PCI\VEN_10DE&DEV_1E04&SUBSYS_250319DA&REV_A1\3&61aaa01&0&48 generates a resource conflict and requires additional installation.

I have more than one GPU. I have 3 gpus.

The ones you see below :

What I'm doing is to choose (from the BIOS) this gpu and I assign it to the host :

at the same time,I reserve the RTX 2080 ti to a guest os (Linux or Windows),by declaring this parameter inside the file /boot/loader.conf :

pptdevs="2/0/0 2/0/1 2/0/2 2/0/3"

Take in consideration that it works inside the Linux vm,but NOT in the Windows vm,because there are some kinds of conflicts between resources that I need to understand.

I ran msinfo32 and then I checked the resource sharing and conflicts tab to see which devices are conflicting with each other and I found something really interesting :

I'm not a developer,but I suspect that a patch is needed for bhyve. Windows needs that ACPI is enabled in bhyve,because I have disabled it between the bhyve parameters and this is what happened :



I tried to disable it in Windows,but every time Windows restarts,it is restored. What's the method to disable it permanently ?

Mario,

You've cross-posted this question to many forums, and other variations on the same theme since 2021.

NTLite forum is a community for users making custom Windows ISO's, by using the NTLite app. While we do answer a few Windows questions, this is a highly technical and narrow question which should be addressed by the FreeBSD & bhyve community.

Disabling ACPI typically creates bad side effects on a running system, especially over GPU drivers.

I don't see anywhere in your previous posts, whether you determined if this problem exists in a bare-metal Windows setup or under Windows Hyper-V, which is the native solution. In either case, you're barking up the wrong tree. This ain't the right place to ask.

more the question is difficult,more developers should be reached to be solved. In case you thought that I make spam: I don't think mine is spam. I'm trying to solve a problem that affects those users who have switched to FreeBSD and want to use it in a desktop-multimedia environment.

---> While we do answer a few Windows questions, this is a highly technical and narrow question which should be addressed by the FreeBSD & bhyve community.

Sure,I posted also there,ma not only. In some cases like this,the correct place to ask is somewhere. Infact "how to disable ACPI on Windows 11" is a question that belongs to a Windows forum.

---> Disabling ACPI typically creates bad side effects on a running system, especially over GPU drivers.

thanks for giving me this clarification. Anyway,as you can see,the questions I make since 2021 aren't exactly the same each time,but there are variations. That's because I'm trying to evaluate the problem from different perspectives.

You could have avoided focusing your attention on the purpose of my project but do it on the specific question I asked, which is in line with the site where I posted it, because it has already been asked. I proposed it again, because the topic was not well developed : here :

Windows 11 - Remove ACPI driver

Hello people, I looked to the NTLite software to try to solve the dropouts problems with the audio that afflict my pc (Dell Latitude 3500 with Motu Ultralite Mk5 interface). From some tests and verifications, in particular with the sw LatencyMon, I have identified that the ACPI.sys driver is the...

For sure not,my RTX 2080 ti works great out of the bhyve hypevisor. And I can pass it without errors if I use a KVM hypevisor.

---> In either case, you're barking up the wrong tree. This ain't the right place to ask.

Again,if you want to help me,please try to keep your attention focused on the question that I've asked,not to what I want to do. Otherwise you make me feel out of place. But since I asked a question relevant to the site (because it's been asked before), I'm in the right place. And my question is part of an ongoing research process on bhyve, it's not just a single question. I cut my teeth on this hypervisor. And I tell you that it can behave in his own way and for this reason I want to try different methods for provoking a reaction from it,because I want to understand which route I should follow.

Do you understand what this community is for? It's for supporting modded Windows images. Your question is spam, because it's mostly irrelevant to folks here. Have you confirmed it works the same on Hyper-V? No, of course not, you're using bhyve on FreeBSD. Neither of which are native Windows solutions.

There are no devs lurking here, other than NTLite's author, who by the way pays this site's hosting costs. And I don't need attitude. One of my friends was a FreeBSD dev who's recognized for making a significant contribution to an industry-standard web backend.

And he would agree, you're out of turn. This is a device driver or virtualization question that only a qualified dev can answer.
