Currently the MemTxResult return value is not propagated, so lost. The motivation behind this series is to make the API more robust to enforce correct use by the consumers.
All series reviewed. Since v2: - Rebased - Removed patches adding MemTxAttrs argument to DMA/PCI API (we will discuss them later). v2: https://www.mail-archive.com/qemu-devel@nongnu.org/msg746761.html The DMA API propagates MemTxResult: - MEMTX_OK, - MEMTX_device_ERROR, - MEMTX_DECODE_ERROR. Let the PCI DMA API propagate them, as they are clearer than an undocumented 'int'.
