      chardev: Use timer instead of bottom-half to postpone open event · ac4119c0
      由 Jan Kiszka 提交于 
      As the block layer may decide to flush bottom-halfs while the machine is
still initializing (e.g. to read geometry data from the disk), our
postponed open event may be processed before the last frontend
registered with a muxed chardev.

Until the semantics of BHs have been clarified, use an expired timer to
achieve the same effect (suggested by Paolo Bonzini). This requires to
perform the alarm timer initialization earlier as otherwise timer
subsystem can be used before being ready.

      This patch mostly mimics what was done to TCP sockets, but simpler
because there is only one address to try.  It also includes a free EINTR

      do not include <libutil.h> needlessly or if it doesn't exist · 3294ce18
      由 Michael Tokarev 提交于 
      <libutil.h> and <util.h> on *BSD (some have one, some another)
were #included just for openpty() declaration.  The only file
where this function is actually used is qemu-char.c.

In vl.c and net/tap-bsd.c, none of functions declared in libutil.h
(login logout logwtmp timdomain openpty forkpty uu_lock realhostname
fparseln and a few others depending on version) are used.

Initially the code which is currently in qemu-char.c was in vl.c,
it has been removed into separate file in commit 0e82f34d
Fri Oct 31 18:44:40 2008, but the #includes were left in vl.c.
So with vl.c, we just remove includes - libutil.h, util.h and
pty.h (which declares only openpty() and forkpty()) from there.

The code in net/tap-bsd.c, which come from net/tap.c, had this

commit 5281d757
Author: Mark McLoughlin <markmc@redhat.com>
Date:   Thu Oct 22 17:49:07 2009 +0100

    net: split all the tap code out into net/tap.c

Note this commit not only moved stuff out of net.c to net/tap.c,
but also rewrote large portions of the tap code, and added these
completely unnecessary #includes -- as usual, I question why such
a misleading commit messages are allowed.

Again, no functions defined in libutil.h or util.h on *BSD are
used by neither net/tap.c nor net/tap-bsd.c.  Removing them.

And finally, the only real user for these #includes, qemu-char.c,
which actually uses openpty().  There, the #ifdef logic is wrong.
A GLIBC-based system has <pty.h>, even if it is a variant of *BSD.
So __GLIBC__ should be checked first, and instead of trying to
include <libutil.h> or <util.h>, we include <pty.h>.  If it is not
GLIBC-based, we check for variations between <*util.h> as before.

This patch fixes build of qemu 1.1 on Debian/kFreebsd (well, one
of the two problems): it is a distribution with a FreeBSD kernel,
so it #defines at least __FreeBSD_kernel__, but since it is based
on GLIBC, it has <pty.h>, but current version does not have neither
<util.h> nor <libutil.h>, which the code tries to include 3 times
but uses only once.

      qemu-option: qemu_opts_create(): use error_set() · 8be7e7e4
      由 Luiz Capitulino 提交于 
      This commit converts qemu_opts_create() from qerror_report() to
error_set().

Currently, most calls to qemu_opts_create() can't fail, so most
callers don't need any changes.

The two cases where code checks for qemu_opts_create() erros are:

 1. Initialization code in vl.c. All of them print their own
    error messages directly to stderr, no need to pass the Error
    object

 2. The functions opts_parse(), qemu_opts_from_qdict() and
    qemu_chr_parse_compat() make use of the error information and
    they can be called from HMP or QMP. In this case, to allow for
    incremental conversion, we propagate the error up using
    qerror_report_err(), which keeps the QError semantics

      Kick io-thread on qemu_chr_accept_input · 98c8ee1d
      由 Jan Kiszka 提交于 
      Once a chr frontend is able to receive input again, we need to inform
the io-thread about this fact. Otherwise, main_loop_wait may continue to
select without the related backend file descriptor in its set. This can
cause high input latencies if only low-rate events arrive otherwise.
