Subject: [PATCH 0/3] fw_cfg: add DMA operations
Date: Fri, 28 Apr 2017 16:45:07 +0400 [thread overview]
Message-ID: <20170428124510.23654-1-marcandre.lureau@redhat.com> (raw)
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.
Marc-André Lureau (3):
fw_cfg: add DMA register
fw_cfg: do DMA read operation
fw_cfg: add DMA write operation proof-of-concept
