Sebastien Boeuf d810c7712d msix: Handle MSI-X vector masking ... The current MSI-X implementation completely ignores the values found in the Vector Control register related to a specific vector, and never updates the Pending Bit Array. According to the PCI specification, MSI-X vectors can be masked through the Vector Control register on bit 0. If this bit is set, the device should not inject any MSI message. When the device runs into such situation, it must not inject the interrupt, but instead it must update the bit corresponding to the vector number in the Pending Bit Array. Later on, if/when the Vector Control register is updated, and if the bit 0 is flipped from 0 to 1, the device must look into the PBA to find out if there was a pending interrupt for this specific vector. If that's the case, an MSI message is injected and the bit from the PBA is cleared. Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com>		2019-06-07 13:33:53 +01:00
