Why does the Intel Agilex® 7 FPGA P-Tile Multi-Channel DMA Intel® FPGA IP for PCI Express* BAM and BAS mode cause host systems to fail to boot when a VFIO-based driver is being used?

Description

Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 22.3 and earlier, the Intel Agilex® 7 FPGA P-Tile Multi-Channel DMA Intel® FPGA IP for PCI Express* Bursting Avalon® Master (BAM) and Bursting Avalon® Slave (BAS) mode configuration incorrectly advertises Function Level Reset (FLR) capability when this is NOT supported in this mode.

This can then cause the host system to fail to boot if Virtual Function IO (VFIO) based driver is used.

Resolution

To stop the Intel Agilex® 7 FPGA P-Tile Multi-Channel DMA Intel® FPGA IP for PCI Express* BAM and BAS incorrectly advertising FLR capability in the Intel® Quartus® Prime Pro Edition Software version 22.3, please install the patch below:
