How is it best to determine if MSI is active for a PCI-E GPU?Ĥ. This contradicts the first question: AMD GPUs use MSI by default, while nVidia GPUs use INT (INT being the older interrupt signaling method) - true or false?ģ. MSI is ALWAYS used on PCI-E because PCI-E simply doesn't support any other interrupt method - true or false? (this is probably false because there are apps that can force MSI on a PCI-E GPU - why do they exist if PCI-E supposedly only uses MSI?)Ģ. Here's a short article about advantages of MSI interrupts - ġ.
Specifically, I'm interested about PCI-E GPUs and interrupts. I've got a few questions about PCI-Express interrupts, because there are many misconceptions on the web regarding them.
