2014-09-26monitor: Reset HMP mon->rs in CHR_EVENT_OPENStratos Psomadakis1-0/+1
Commit cdaa86a54 ("Add G_IO_HUP handler for socket chardev") exposed a bug in the way the HMP monitor handles its command buffer. When a client closes the connection to the monitor, tcp_chr_read() will detect the G_IO_HUP condition and call tcp_chr_disconnect() to close the server-side connection too. Due to the fact that monitor reads 1 byte at a time (for each tcp_chr_read()), the monitor readline state / buffers might contain junk (i.e. a half-finished command). Thus, without calling readline_restart() on mon->rs in CHR_EVENT_OPEN, future HMP commands will fail.

2014-06-30serial: poll the serial console with G_IO_HUPRoger Pau Monne1-1/+1
On FreeBSD polling a master pty while the other end is not connected with G_IO_OUT only results in an endless wait. This is different from the Linux behaviour, that returns immediately. In order to demonstrate this, I have the following example code: http://xenbits.xen.org/people/royger/test_poll.c When executed on Linux: $ ./test_poll In callback On FreeBSD instead, the callback never gets called: $ ./test_poll So, in order to workaround this, poll the source with G_IO_HUP (which makes the code behave the same way on both Linux and FreeBSD).

The monitor is now hooked on the new event mechanism, so that later patches can convert event callers one by one. Most code are copied from old monitor_protocol_* functions with some modification. Note that two build time warnings will be raised after this patch. One is caused by no caller of monitor_qapi_event_throttle(), the other one is caused by QAPI_EVENT_MAX = 0.

2014-06-16monitor: QEMU Monitor Instruction Disassembly Incorrect for PowerPC LE ModeTom Musta1-0/+4
The monitor support for disassembling instructions does not honor the MSR[LE] bit for PowerPC processors. This change enhances the monitor_disas() routine by supporting a flag bit for Little Endian mode. Bit 16 is used since that bit was used in the analagous guest disassembly routine target_disas(). Also, to be consistent with target_disas(), the disassembler bfd_mach field can be passed in the flags argument.
