From: Alex Williamson <alex.williamson@xxxxxxxxxx> [ Upstream commit 2910306655a7072640021563ec9501bfa67f0cb1 ] Per user reports, the Creative Labs EMU20k2 (Sound Blaster X-Fi Titanium Series) generates spurious interrupts when used with vfio-pci unless DisINTx masking support is disabled. Thus, quirk the device to mark INTx masking as broken.
