2010-03-16error: Move qemu_error & friends into their own headerMarkus Armbruster16-15/+26
2010-03-16error: Simplify error sink setupMarkus Armbruster4-77/+9
qemu_error_sink can either point to a monitor or a file. In practice, it always points to the current monitor if we have one, else to stderr. Simply route errors to the current monitor or else to stderr, and remove qemu_error_sink along with the functions to control it. Actually, the old code switches the sink slightly later, in handle_user_command() and handle_qmp_command(), than it gets switched now, implicitly, by setting the current monitor in monitor_read() and monitor_control_read(). Likewise, it switches back slightly earlier (same places). Doesn't make a difference, because there are no calls of qemu_error() in between.
2010-03-16error: Move qemu_error() & friends from monitor.c to own fileMarkus Armbruster3-89/+93
They're about reporting errors, not about the monitor.
2010-03-16monitor: Factor monitor_set_error() out of qemu_error_internal()Markus Armbruster2-8/+16
This separates the monitor part from the QError part.
2010-03-16block: Simplify usb_msd_initfn() test for "can read bdrv key"Markus Armbruster1-1/+1
The old test assumes that "hotplugged" implies "we have a current monitor for reading the key". This is in fact true, but it's not obviously true. Aside: if it were false, we could pass a null pointer to monitor_read_bdrv_key_start(), which would then crash. The previous commit permits us to check for "we have a current monitor" directly, so do that.
2010-03-16monitor: Separate "default monitor" and "current monitor" cleanlyMarkus Armbruster5-9/+10
Commits 376253ec..731b0364 introduced global variable cur_mon, which points to the "default monitor" (if any), except during execution of monitor_read() or monitor_control_read() it points to the monitor from which we're reading instead (the "current monitor"). Monitor command handlers run within monitor_read() or monitor_control_read(). Default monitor and current monitor are really separate things, and squashing them together is confusing and error-prone. For instance, usb_host_scan() can run both in "info usbhost" and periodically via usb_host_auto_check(). It prints to cur_mon, which is what we want in the former case: the monitor executing "info usbhost". But since that's the default monitor in the latter case, it periodically spams the default monitor there. A few places use cur_mon to log stuff to the default monitor. If we ever log something while cur_mon points to current monitor instead of default monitor, the log temporarily "jumps" to another monitor. Whether that can or cannot happen isn't always obvious. Maybe logging to the default monitor (which may not even exist) is a bad idea, and we should log to stderr or a logfile instead. But that's outside the scope of this commit. Change cur_mon to point to the current monitor. Create new default_mon to point to the default monitor. Update users of cur_mon accordingly. This fixes the periodical spamming of the default monitor by usb_host_scan(). It also stops "log jumping", should that problem exist.
2010-03-16tools: Remove unused cur_mon from qemu-tool.cMarkus Armbruster1-2/+0
2010-03-16pc: Factor common code out of pc_boot_set() and cmos_init()Markus Armbruster1-20/+8
Code duplicated in commit 0ecdffbb. The two versions are similar, but not identical: * cmos_init() reports errors to stderr, pc_boot_set() via qemu_error(). The latter is fine for both, so pick that for the common code. * cmos_init() obeys fd_bootchk, pc_boot_set() ignores it. Make it a parameter of the common code.
2010-03-16pc: Fix error reporting for -boot onceMarkus Armbruster1-4/+3
Commit 0ecdffbb created pc_boot_set() for use from monitor command "boot_set", via qemu_boot_set(). pc_boot_set() reports errors to cur_mon, which works fine for monitor code. Commit e0f084bf reused the function int reset handler restore_boot_devices(). Use of cur_mon is problematic in that context. For instance, the "Too many boot devices for PC" error for "-boot order=abcdefgh,once=c" goes to the monitor instead of stderr. The monitor may not even exist. Fix by switching to qemu_error().
2010-03-16savevm: Fix -loadvm to report errors to stderr, not the monitorMarkus Armbruster4-16/+14
A monitor may not even exist. Change load_vmstate() to use qemu_error() instead of monitor_printf(). Parameter mon is now unused, remove it.
2010-03-16usb: Remove disabled monitor_printf() in usb_read_file()Markus Armbruster1-8/+0
The monitor_printf() reports failure. Printing is wrong, because the caller tries various arguments, and expects the function to fail for some or all. Disabled since commit 26a9e82a. Remove it.

2010-03-10QMP: Really move the RESET event to qemu_system_reset()Luiz Capitulino1-2/+1
Something bad has happened in the merge of commit 0ee44250, as the log message says it's supposed to be in qemu_system_reset() but it is do_vm_stop(). Possibly, it was a problem with the conflict resolution with ea375f9a (which has been merged first). This commit moves (again) the RESET event into qemu_system_reset().

2010-03-10target-i386: fix SIB decoding with index = 4Aurelien Jarno1-2/+2
A SIB byte with an index of 4 means "no scaled index", even if the scale value is not 0. In 64-bit mode, if REX.X is used, an index of 4 selects %r12. This is correctly handled by the computation of the index variable, which includes the index bits, and also the REX.X prefix: index = ((code >> 3) & 7) | REX_X(s); Thanks to Avi Kivity, Jamie Lokier and Malc for the analysis of the problem and the initial patch.

2010-03-09kbd keds: vncGerd Hoffmann2-1/+20
Use led status notification support in vnc. The qemu vnc server keeps track of the capslock and numlock states based on the key presses it receives from the vnc client. But this fails in case the guests idea of the capslock and numlock state changes for other reasons. One case is guest reboot (+ keyboard reset). Another case are more recent windows versions which reset capslock state before presenting the login screen. Usually guests use the keyboard leds to signal the capslock and numlock state to the user, so we can use this to better keep track of capslock and numlock state in the qemu vnc server. Also toggle the numlock and capslock states on keydown events (instead of keyup). Guests do the same.

Property "vlan" reports "failed to parse" even when the value parses just fine, but the result doesn't name an existing VLAN. Similarly, properties "drive", "chr" and "netdev" misleadingly report "failed to parse" when the value doesn't name an existing host device. Change PropertyInfo method parse to return an error code, so that qdev_prop_parse() can report the error more accurately.
