[Qemu-devel] [PATCH v2 2/4] fw_cfg: do DMA read operation
From: Marc-André LureauModify fw_cfg_read_blob() to use DMA if the device supports it. Return errors, because the operation may fail. This is a proof-of-concept patch with some FIXME. It uses yield() to wait for the memory to be cleared. Help on how to improve this
