Questions about MSI limits in GoInterruptPolicy

[dermodemon]

1. What are those MSI limit parameters and what are they doing?
2. Can i go higher than a default MSI limit (my XHCI limit is 8, what will happen when i set it to 32 for example)?
3. Why my gpu msi limit is only 1 and XHCI for example is 8?

I would advise against doing any modification to the driver default MSI limit, this is something done on a driver software level and it can lead to issues if you change it.
Instead, consider trying to change the core (default is Core 0 for all drivers) in which the DPC/ISR's are being executed.
This can lead to benefits.

Which drivers can be bound to the kernel and which ones should not be touched to avoid a BSOD?
