From: Marc-André Lureau <marcandre.lureau@redhat.com> Hi, This series brings DMA operations support to the fw_cfg kernel module. There is a few FIXME that I don't know how to improve. The 'write' operation is only meant as a proof-of-concept, since some qemu firmware maintainers are strongly against the usage of this operation by the kernel/user-space.
