The CPUID level value on Conroe, Penryn, and Nehalem are too low.

2013-06-10target-i386: Update model values on Conroe/Penryn/Nehalem CPU modelsEduardo Habkost
The CPUID model values on Conroe, Penryn, and Nehalem are too conservative and don't reflect the values found on real Conroe, Penryn, and Nehalem CPUs. This causes at least one known problems: Windows XP disables sysenter when (family == 6 && model <= 2), but Skype tries to use the sysenter instruction anyway because it is reported as available on CPUID, making it crash. This patch sets appropriate model values that correspond to real Conroe, Penryn, and Nehalem CPUs.

2013-06-10qemu-char: don't issue CHR_EVENT_OPEN in a BHMichael Roth
When CHR_EVENT_OPENED was initially added, it was CHR_EVENT_RESET, and it was issued as a bottom-half: 86e94dea5b740dad65446c857f6959eae43e0ba6 Which we basically used to print out a greeting/prompt for the monitor. AFAICT the only reason this was ever done in a BH was because in some cases we'd modify the chr_write handler for a new chardev backend *after* the site where we issued the reset (see: 86e94d:qemu_chr_open_stdio()) At some point this event was renamed to CHR_EVENT_OPENED, and we've maintained the use of this BH ever since. However, due to 9f939df955a4152aad69a19a77e0898631bb2c18, we schedule the BH via g_idle_add(), which is causing events to sometimes be delivered after we've already begun processing data from backends, leading to: known bugs: QMP: session negotation resets with OPENED event, in some cases this is causing new sessions to get sporadically reset potential bugs: hw/usb/redirect.c: can_read handler checks for dev->parser != NULL, which may be true if CLOSED BH has not been executed yet. In the past, OPENED quiesced outstanding CLOSED events prior to us reading client data. If it's delayed, our check may allow reads to occur even though we haven't processed the OPENED event yet, and when we do finally get the OPENED event, our state may get reset. qtest.c: can begin session before OPENED event is processed, leading to a spurious reset of the system and irq_levels gdbstub.c: may start a gdb session prior to the machine being paused To fix these, let's just drop the BH. Since the initial reasoning for using it still applies to an extent, work around that by deferring the delivery of CHR_EVENT_OPENED until after the chardevs have been fully initialized, toward the end of qmp_chardev_add() (or some cases, qemu_chr_new_from_opts()). This defers delivery long enough that we can be assured a CharDriverState is fully initialized before CHR_EVENT_OPENED is sent. Also, rather than requiring each chardev to do an explicit open, do it automatically, and allow the small few who don't desire such behavior to suppress the OPENED-on-init behavior by setting a 'explicit_be_open' flag. We additionally add missing OPENED events for stdio backends on w32, which were previously not being issued, causing us to not recieve the banner and initial prompts for qmp/hmp.

I'm facing two problems lately wrt QMP patch review: increasingly lack of bandwidth and lack of background in so many different areas that are getting new QMP commands almost every week. In order to help me mitigate this problem, I'm adding Eric and Markus (besides me) as maintainers of the qapi-schema.json file. Markus has been an old timer reviewer. Eric is being the most active and prolific reviewer of QMP patches for some time now. I believe Markus and Eric will keep doing their work as before, but starting now I'll require the ACK of at least one of them before appling a patch/series that touches the qapi-schema.json file.

This patch forbid the following invalid parameters to tap: 1) fd and vhostfds were specified but vhostfd were not specified 2) vhostfds were specified but fds were not specified 3) fds and vhostfd were specified For 1 and 2, net_init_tap_one() will still pass NULL as vhostfdname to monitor_handle_fd_param(), which may crash the qemu. Also remove the unnecessary has_fd check.

2013-06-06ide: Set BSY bit during FLUSHAndreas Färber
The implementation of the ATA FLUSH command invokes a flush at the block layer, which may on raw files on POSIX entail a synchronous fdatasync(). This may in some cases take so long that the SLES 11 SP1 guest driver reports I/O errors and filesystems get corrupted or remounted read-only. Avoid this by setting BUSY_STAT, so that the guest is made aware we are in the middle of an operation and no ATA commands are attempted to be processed concurrently. Addresses BNC#637297.
