[Qemu-devel] [PATCH 0/3] fw_cfg: add DMA operations

From: Marc-André Lureau <address@hidden>


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.

Marc-André Lureau (3):
  fw_cfg: add DMA register
  fw_cfg: do DMA read operation
  fw_cfg: add DMA write operation proof-of-concept
