Clemens Ladisch a5ee4eb754 PCI quirk: RS780/RS880: work around missing MSI initialization ... AMD says in section 2.5.4 (GFX MSI Enable) of #43291 (AMD 780G Family Register Programming Requirements): The SBIOS must enable internal graphics MSI capability in GCCFG by setting the following: NBCFG.NB_CNTL.STRAP_MSI_ENABLE='1' Quite a few BIOS writers misinterpret this sentence and think that enabling MSI is an optional feature. However, clearing that bit just prevents delivery of MSI messages but does not remove the MSI PCI capabilities registers, and so leaves these devices unusable for any driver that attempts to use MSI. Setting that bit is not possible after the BIOS has locked down the configuration registers, so we have to manually disable MSI for the affected devices. This fixes the codec communication errors in the HDA driver when accessing the HDMI audio device, and allows us to get rid of the overcautious quirk in radeon_irq_kms.c.
