[Qemu-devel] [PATCH v4 0/10] qemu-binfmt-conf.sh

[Unai Martinez-Corral <unai.martinezcorral@ehu.eus>]

Hi,

This series reworks qemu-binfmt-conf.sh:

* Argument <CPU> from option '--systemd' is generalized to <TARGETS>, and it is
  accepted for any mode (default, debian or systemd). It can be a single target
  arch or a list of them.
* Option '--clear' is added, which allows to remove an already registered
  target interpreter or a list of them. The implementation is functional but
  partial. Please, see the corresponding commit.
* Option '--test|--dry-run' is added, which allows to execute the CHECK according
  to the provided arguments, but no interpreter is configured.
* Support to set options through environment variables: QEMU_TARGETS,
  QEMU_PATH, QEMU_SUFFIX, QEMU_PERSISTENT, QEMU_CREDENTIAL, QEMU_CLEAR and
  QEMU_TEST.

The following changes are not backward compatible:

* Option '--persistent' no longer requires/accepts an argument.
* Option '--credential' no longer requires/accepts an argument.
* Option '--systemd' no longer requires/accepts an argument.
* Option '--qemu-path' is renamed to '--path'.
* Option '--qemu-suffix' is renamed to '--suffix'.

The functionality of all of them is untouched. Changes are related to syntax only.

The main differences compared to v3 are:

* Suggestions by Laurent Vivier regarding syntax and usage of redundant variables are
  addressed.
* The same presentation format as for qemu-XXXX ("Argument Env-variable Description")
  is used and defaults for envvars are shown.
* '--reset' (now '--clear') is exclusive, i.e., the list of positional arguments is used,
  and no registration function is executed.
* Commas are no longer accepted as separators for TARGETS.
* The order of some patches is reorganized and some are squashed:
  * v4 4/10 is new
  * v3 4/10 -> v4 5/10
  * v3 5/10 -> v4 6/10
  * v3 6/10 and 10/10 --> v4 7/10
  * v3 7/10 -> v4 8/10
  * v3 8/10 and v3 9/10 --> v4 9/10
  * v4 10/10 is new

Based on:

* [PATCH v3 0/10] qemu-binfmt-conf.sh
* [PATCH v2] qemu-binfmt-conf.sh: add CPUS, add --reset, make -p and -c boolean (no arg)
* [PATCH] qemu-binfmt-conf.sh: add CPUS, add --reset, make -p and -c boolean (no arg)
