2010-04-10boot: remove unused boot_devices_bitmap variableEduardo Habkost
In addition to removing the variable, this also renames the parse_bootdevices() function to validate_bootdevices(), as we don't need its return value anymore.

2010-04-10net: remove broken net_set_boot_mask() boot device validationEduardo Habkost
There are many problems with net_set_boot_mask(): 1) It is broken when using the device model instead of "-net nic". Example: $ qemu-system-x86_64 -device rtl8139,vlan=0,id=net0,mac=52:54:00:82:41:fd,bus=pci.0,addr=0x4 -net user,vlan=0,name=hostnet0 -vnc 0.0.0.0:0 -boot n Cannot boot from non-existent NIC $ 2) The mask was previously used to set which boot ROMs were supposed to be loaded, but this was changed long time ago. Now all ROM images are loaded, and SeaBIOS takes care of jumping to the right boot entry point depending on the boot settings. 3) Interpretation and validation of the boot parameter letters is done on the machine type code. Examples: PC accepts only a,b,c,d,n as valid boot device letters. mac99 accepts only a,b,c,d,e,f. As a side-effect of this change, qemu-kvm won't abort anymore if using "-boot n" on a machine with no network devices. Checking if the requested boot device is valid is now a task for the BIOS or the machine-type code.

2010-03-29Refactor target specific handling, compile vl.c only onceBlue Swirl
Move target specific functions and RAM handling to arch_init.c. Add a flag to QEMUOptions structure to indicate for which architectures the option is allowed, check the flag in run time and remove conditional code in option handling.

2010-03-19Introduce a default qmp sessionAnthony Liguori
Basically, -qmp unix:%{home}/.qemu/qmp/%{uuid}.sock,server,nowait %{uuid} will be -uuid if it's specified, otherwise, if libuuid is available, we generate a uuid. If it's not available, we don't create one. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-03-19qmp: don't make -qmp disable the default monitorAnthony Liguori
Instead, we introduce a default_qmp flag. We don't use it yet, but will in the next patch. This has a user-visible impact as specifying just -qmp will now also show a monitor on the 'vc'. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-03-19Convert atexit users to exit_notifierAnthony Liguori
All of these users have global state so we really don't see a benefit from exit_notifier. However, using exit_notifier means that there's one less justification for having global state in the first place. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-03-17tweak qemu_notify_eventPaolo Bonzini
Instead of testing specially next_cpu in host_alarm_handler, just do that in qemu_notify_event. The idea is, if we are not running (or not yet running) target CPU code, prepare things so that the execution loop is exited asap; just make that clear.

2010-03-17do not use qemu_event_increment outside qemu_notify_eventPaolo Bonzini
qemu_notify_event in the non-iothread case is only stopping the current CPU. However, if the CPU is idle and the main loop is in the select call then a call to qemu_event_increment is needed too (as done in host_alarm_handler). Since in general one doesn't know whether the CPU is executing or not, it is a safe bet to always do qemu_event_increment. Another way to see it: after this patch qemu_event_increment is the "common part" of qemu_notify_event for both the CONFIG_IOTHREAD and !CONFIG_IOTHREAD cases, which makes sense.

2010-03-17more alarm timer cleanupPaolo Bonzini
The timer_alarm_pending variable is related to the alarm timer but not placed in the struct. Also, in qemu_mod_timer the wrong flag was being tested: the timer is rearmed in the alarm timer "bottom half", so the right flag to test there is the "pending" flag. Finally, I hoisted the NULL checks from alarm_has_dynticks to host_alarm_handler. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-03-17avoid dubiously clever code in win32_start_timerPaolo Bonzini
The code is initializing an unsigned int to UINT_MAX using "-1", so that the following always-true comparison seems to be always-false at a first look. Since alarm timer initializations are never nested, it is simpler to unconditionally store the result of timeGetDevCaps into data->period.

2010-03-16qemu-option: Move the implied first name into QemuOptsListMarkus Armbruster
We sometimes permit omitting the first option name, for example -device foo is short for -device driver=foo. The name to use ("driver" in the example) is passed as argument to qemu_opts_parse(). For each QemuOptsList, we use at most one such name. Move the name into QemuOptsList, and pass whether to permit the abbreviation. This ensures continued consistency, and simplifies the commit after next in this series.
2010-03-16error: Track locations on command lineMarkus Armbruster
New LOC_CMDLINE. Use it for tracking option with argument in lookup_opt(). We now report errors like this qemu: -device smbus-eeprom: Did not find I2C bus for smbus-eeprom
2010-03-16error: Track locations in configuration filesMarkus Armbruster
New LOC_FILE. Use it for tracking file name and line number in qemu_config_parse(). We now report errors like qemu:foo.conf:42: Did not find I2C bus for smbus-eeprom In particular, gems like this message: -device: no driver specified become almost nice now: qemu:foo.conf:44: -device: no driver specified (A later commit will get rid of the bogus -device:)
