  "message": "dma: return empty dirty bitmap for unmapped or message-based regions (#877)\n\nTo align with kernel VFIO uAPI behavior, the server should not fail the\nmigration when asked to report dirty pages for unmapped or non-FD DMA\nregions.\n\nFor regions accessed via messages (REGION_ACCESS_MODE_MSG) or unmapped\nfirmware/MMIO regions, the client physically executes the memory writes\nand natively tracks them in its own dirty bitmap.\n\nReturn an empty (zeroed) bitmap instead of -EINVAL for these regions\nso the client migration does not crash.\n\nSigned-off-by: Hugo Komatsu \u003chugo.komatsu@nutanix.com\u003e",
