2013-06-28vl: convert -smp to qemu_opts_parse()Michael Tokarev
This also introduces a new suboption, "cpus=", which is the default. So after this patch, -smp n,sockets=y is the same as -smp cpus=n,sockets=y (with "cpu" being some generic thing, referring to either cores, or threads, or sockets, as before). We still don't validate relations between different numbers, for example it is still possible to say -smp 1,sockets=10 and it will be accepted to mean sockets=1.

2013-06-19vl: Fix -boot order and once regressions, and related bugsMarkus Armbruster
Option "once" sets up a different boot order just for the initial boot. Boot order reverts back to normal on reset. Option "order" changes the normal boot order. The reversal is implemented by reset handler restore_boot_devices(), which takes the boot order to revert to as argument. restore_boot_devices() does nothing on its first call, because that must be the initial machine reset. On its second call, it changes the boot order back, and unregisters itself. Because we register the handler right when -boot gets parsed, we can revert to an incorrect normal boot order, and multiple -boot can interact in funny ways. Here's how things work without -boot once or order: * boot_devices is "". * main() passes machine->boot_order to to machine->init(), because boot_devices is "". machine->init() configures firmware accordingly. For PC machines, machine->boot_order is "cad", and pc_cmos_init() writes it to RTC CMOS, where SeaBIOS picks it up. Now consider -boot order=: * boot_devices is "". * -boot order= sets boot_devices to "" (no change). * main() passes machine->boot_order to to machine->init(), because boot_devices is "", as above. Bug: -boot order= has no effect. Broken in commit e4ada29e. Next, consider -boot once=a: * boot_devices is "". * -boot once=a registers restore_boot_devices() with argument "", and sets boot_devices to "a". * main() passes boot_devices "a" to machine->init(), which configures firmware accordingly. For PC machines, pc_cmos_init() writes the boot order to RTC CMOS. * main() calls qemu_system_reset(). This runs reset handlers. - restore_boot_devices() gets called with argument "". Does nothing, because it's the first call. * Machine boots, boot order is "a". * Machine resets (e.g. monitor command). Reset handlers run. - restore_boot_devices() gets called with argument "". Calls qemu_boot_set("") to reconfigure firmware. For PC machines, pc_boot_set() writes it into RTC CMOS. Reset handler unregistered. Bug: boot order reverts to "" instead of machine->boot_order. The actual boot order depends on how firmware interprets "". Broken in commit e4ada29e. Next, consider -boot once=a -boot order=c: * boot_devices is "". * -boot once=a registers restore_boot_devices() with argument "", and sets boot_devices to "a". * -boot order=c sets boot_devices to "c". * main() passes boot_devices "c" to machine->init(), which configures firmware accordingly. For PC machines, pc_cmos_init() writes the boot order to RTC CMOS. * main() calls qemu_system_reset(). This runs reset handlers. - restore_boot_devices() gets called with argument "". Does nothing, because it's the first call. * Machine boots, boot order is "c". Bug: it should be "a". I figure this has always been broken. * Machine resets (e.g. monitor command). Reset handlers run. - restore_boot_devices() gets called with argument "". Calls qemu_boot_set("") to reconfigure firmware. For PC machines, pc_boot_set() writes it into RTC CMOS. Reset handler unregistered. Bug: boot order reverts to "" instead of "c". I figure this has always been broken, just differently broken before commit e4ada29e. Next, consider -boot once=a -boot once=b -boot once=c: * boot_devices is "". * -boot once=a registers restore_boot_devices() with argument "", and sets boot_devices to "a". * -boot once=b registers restore_boot_devices() with argument "a", and sets boot_devices to "b". * -boot once=c registers restore_boot_devices() with argument "b", and sets boot_devices to "c". * main() passes boot_devices "c" to machine->init(), which configures firmware accordingly. For PC machines, pc_cmos_init() writes the boot order to RTC CMOS. * main() calls qemu_system_reset(). This runs reset handlers. - restore_boot_devices() gets called with argument "". Does nothing, because it's the first call. - restore_boot_devices() gets called with argument "a". Calls qemu_boot_set("a") to reconfigure firmware. For PC machines, pc_boot_set() writes it into RTC CMOS. Reset handler unregistered. - restore_boot_devices() gets called with argument "b". Calls qemu_boot_set("b") to reconfigure firmware. For PC machines, pc_boot_set() writes it into RTC CMOS. Reset handler unregistered. * Machine boots, boot order is "b". Bug: should really be "c", because that came last, and for all other -boot options, the last one wins. I figure this was broken some time before commit 37905d6a, and fixed there only for a single occurence of "once". * Machine resets (e.g. monitor command). Reset handlers run. - restore_boot_devices() gets called with argument "". Calls qemu_boot_set("") to reconfigure firmware. For PC machines, pc_boot_set() writes it into RTC CMOS. Reset handler unregistered. Same bug as above: boot order reverts to "" instead of machine->boot_order. Fix by acting upon -boot options order, once and menu only after option parsing is complete, and the machine is known. This is how the other -boot options work already.

2013-06-19vl: Clean up parsing of -boot option argumentMarkus Armbruster
Commit 3d3b8303 threw in some QemuOpts parsing without replacing the existing ad hoc parser, resulting in a confusing mess. Clean it up. Two user-visible changes: 1. Invalid options are reported more nicely. Before: qemu: unknown boot parameter 'x' in 'x=y' After: qemu-system-x86_64: -boot x=y: Invalid parameter 'x' 2. If -boot is given multiple times, options accumulate, just like for -machine. Before, only options order, once and menu accumulated. For the other ones, all but the first -boot in non-legacy syntax got simply ignored.

2013-06-16vl: always define no_frameMichael Tokarev
Commit 047d4e151dd46 "Unbreak -no-quit for GTK, validate SDL options" broke build of qemu without sdl, by referencing `no_frame' variable which is defined inside #if SDL block. Fix that by defining that variable unconditionally. This is a better fix for the build issue introduced by that patch than a revert. This change keeps the new functinality introduced by that patch and just fixes the compilation. It still is not a complete fix around the original issue (not working -no-frame et al with -display gtk), because it makes only the legacy interface working, not the new suboption interface, so a few more changes are needed.

2013-06-11Unbreak -no-quit for GTK, validate SDL optionsPeter Wu
Certain options (-no-frame, -alt-grab, -ctrl-grab) only make sense with SDL. When compiling without SDL, these options (and -no-quit) print an error message and exit qemu. In case QEMU is compiled with SDL support, the three aforementioned options still do not make sense with other display types. This patch addresses that issue by printing a warning. I have chosen not to exit QEMU afterwards because having the option is not harmful and before this patch it would be ignored anyway. By delaying the sanity check from compile-time with some ifdefs to run-time, -no-quit is now also properly supported when compiling without SDL.

2013-03-12Add search path support for qemu data files.Gerd Hoffmann
This patch allows to specify multiple directories where qemu should look for data files. To implement that the behavior of the -L switch is slightly different now: Instead of replacing the data directory the path specified will be appended to the data directory list. So when specifiying -L multiple times all directories specified will be checked, in the order they are specified on the command line, instead of just the last one. Additionally the default paths are always appended to the directory data list. This allows to specify a incomplete directory (such as the seabios out/ directory) via -L. Anything not found there will be loaded from the default paths, so you don't have to create a symlink farm for all the rom blobs. For trouble-shooting a tracepoint has been added, logging which blob has been loaded from which location.

2013-03-12Add support for cancelling of a TPM commandStefan Berger
This patch adds support for cancelling an executing TPM command. In Linux for example a user can cancel a command through the TPM's sysfs 'cancel' entry using echo "1" > /sysfs/class/misc/tpm0/device/cancel This patch propagates the cancellation of a command inside a VM to the host TPM's sysfs entry. It also uses the possibility to cancel the command before QEMU VM shutdown or reboot, which helps in preventing QEMU from hanging while waiting for the completion of the command. To relieve higher layers or users from having to determine the TPM's cancel sysfs entry, the driver searches for the entry in well known locations.

2013-03-12Support for TPM command line optionsStefan Berger
This patch adds support for TPM command line options. The command line options supported here are ./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id> -device tpm-tis,tpmdev=<id>,id=<other id> and ./qemu-... -tpmdev help where the latter works similar to -soundhw help and shows a list of available TPM backends (for example 'passthrough'). Using the type parameter, the backend is chosen, i.e., 'passthrough' for the passthrough driver. The interpretation of the other parameters along with determining whether enough parameters were provided is pushed into the backend driver, which needs to implement the interface function 'create' and return a TPMDriverOpts structure if the VM can be started or 'NULL' if not enough or bad parameters were provided. Monitor support for 'info tpm' has been added. It for example prints the following: (qemu) info tpm TPM devices: tpm0: model=tpm-tis \ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Reviewed-by: Corey Bryant <coreyb@linux.vnet.ibm.com> Reviewed-by: Joel Schopp <jschopp@linux.vnet.ibm.com> Message-id: 1361987275-26289-2-git-send-email-stefanb@linux.vnet.ibm.com Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2013-03-01hw: move qdev-monitor.o to toplevel directoryPaolo Bonzini
qdev-monitor.c is the only "core qdev" file that is not used in user-mode emulation, and it does not define anything that is used by hardware models. Remove it from the hw/ directory and remove hw/qdev-monitor.h from hw/qdev.h too; this requires some files to have some new explicitly includes. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2013-02-26gtk ui: unbreak spiceGerd Hoffmann
Merge of the gtk ui brought a initialitation order issue for spice: The using_spice variable isn't set yet when checked, leading to the default UI being activated (additionally to spice remote access). Let's set display_remote when we find a -spice switch on the command line, like we do for vnc.

2013-02-21gtk: make default UI (v5)Anthony Liguori
A user can still enable SDL with '-sdl' or '-display sdl' but start making the default display GTK by default. I'd also like to deprecate the SDL display and remove it in a few releases.
