[Qemu-devel] [RFC 00/13]: convert device_add to the qapi |

This is an RFC because it's not 100% finished yet and I'm not sure if some
of the changes are the way to go.
Here's a summary of the series its issues, more details can be found in
the patches:
o Patches 1 to 11 convert several qemu-option and qemu-config functions
from qerror_report() to error_set(). Note that not all users of those
functions are converted, so it might be needed to call qerror_report_err()
somewhere in the call stack to keep QError semantics.
Also, new versions of qemu_opt_set() and qemu_find_opts() that take an
Error parameter are introduced. This allows for incremental conversion
(vs. converting 100% of their users in one series)
o Patch 12 introduces support for allowing QAPI functions to accept a
variable list of arguments, which are unchecked and passed "as-is"
to the QAPI function. My implementation here is very hacky, please
check the patch for details
o Patch 13 does the QAPI conversion itself, but the HMP version of
device_add lacks its help text (ie. '?'). The problem here is that hmp.c
is really a QMP client and can only use what's provided by QMP. There are
two ways to solve this:
1. Anthony told me that he has this implemented in his tree, but
I couldn't find it. Anthony, can you point me to your
implementation?
2. Add a query-drivers command or similar to get a list of drivers,
so that the HMP command can use it to implement the help text
