[Qemu-devel] [PATCH v3 0/5] fw-cfg: docs, cleanup, and user-provided cmd

From: Gabriel L. Somlo
Subject: [Qemu-devel] [PATCH v3 0/5] fw-cfg: docs, cleanup, and user-provided cmdline blobs
Date: Sat, 21 Mar 2015 16:23:45 -0400

Document and clean up fw_cfg; additionally, allow user-provided blobs to
be inserted into fw_cfg via the qemu command line.

Changes since v2:

    - entire series depends on (applies on top of) another fw_cfg patch:
      which is currently queued for 2.3.0-rc.

    - documentation (1/5) is now correct about all architectures using
      fw_cfg revision 0x1 :)

    - patches 2/5, 3/5, and 4/5 are unchanged

    - patch 5/5 (command-line insertion of fw_cfg blob) is now using
      qemu_opts_foreach() after machine_init, and is therefore
      compliant with -writeconfig and -readconfig (thanks again Laszlo,
      Gerd, and Markus for the quick tutorial!).
      Also, ee additional comments below the commit log in the actual
      patch message.


Gabriel L. Somlo (5):
  fw_cfg: add documentation file (docs/specs/fw_cfg.txt)
  fw_cfg: remove support for guest-side data writes
  fw_cfg: prevent selector key conflict
  fw_cfg: prohibit insertion of duplicate fw_cfg file names
  fw_cfg: insert fw_cfg file blobs via qemu cmdline
