Hi, While working on fixing the emulated nvme device to pass more tests in the blktests suite, I discovered that the pci_dma_rw function ignores the return value of dma_memory_rw.
The nvme device needs to handle DMA errors gracefully in order to pass the block/011 test ("disable PCI device while doing I/O") in the blktests suite. This is only possible if the device knows if the DMA transfer was successful or not. I can't see what the reason for ignoring the return value would be. But if there is a good reason, please enlighten me :) Klaus Jensen (1): pci: pass along the return value of dma_memory_rw include/hw/pci/pci.h | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) -- 2.23.0
