      Add the "-semihosting-config" option. · a38bb079
      Liviu Ionescu 提交于
      The usual semihosting behaviour is to process the system calls locally and
      return; unfortuantelly the initial implementation dinamically changed the
      target to GDB during debug sessions, which, for the usual arm-none-eabi-gdb,
      is not implemented. The result was that during debug sessions the semihosting
      calls were discarded.
      
      This patch adds a configuration variable and an option to set it on the
      command line:
      
          -semihosting-config [enable=on|off,]target=native|gdb|auto
      
      This option enables semihosting and defines where the semihosting calls will
      be addressed, to QEMU ('native') or to GDB ('gdb'). The default is auto, which
      means 'gdb' during debug sessions and 'native' otherwise.

      sysbus: Make devices spawnable via -device · 33cd52b5
      Alexander Graf 提交于
      Now that we can properly map sysbus devices that haven't been connected to
      something forcefully by C code, we can allow the -device command line option
      to spawn them.
      
      For machines that don't implement dynamic sysbus assignment in their board
      files we add a new bool "has_dynamic_sysbus" to the machine class.
      When that property is false (default), we bail out when we see dynamically
      spawned sysbus devices, like we did before.

      smbios: Encode UUID according to SMBIOS specification · caad057b
      Eduardo Habkost 提交于
      Differently from older versions, SMBIOS version 2.6 is explicit about
      the encoding of UUID fields:
      
      > Although RFC 4122 recommends network byte order for all fields, the PC
      > industry (including the ACPI, UEFI, and Microsoft specifications) has
      > consistently used little-endian byte encoding for the first three fields:
      > time_low, time_mid, time_hi_and_version. The same encoding, also known as
      > wire format, should also be used for the SMBIOS representation of the UUID.
      >
      > The UUID {00112233-4455-6677-8899-AABBCCDDEEFF} would thus be represented
      > as 33 22 11 00 55 44 77 66 88 99 AA BB CC DD EE FF.
      
      The dmidecode tool implements this and decodes the above "wire format"
      when SMBIOS version >= 2.6. We moved from SMBIOS version 2.4 to 2.8 when
      we started building the SMBIOS entry point inside QEMU, on commit
      c97294ec.
      
      Change smbios_build_type_1_table() to encode the UUID as specified.
      
      To make sure we won't change the guest-visible UUID when upgrading to a
      newer QEMU version, keep the old behavior on pc-*-2.1 and older.

      VMWare apparently doesn't like running under QEMU due to our
      incomplete emulation of it's special IO Port.  This adds a
      pc & q35 property to allow it to be turned off.

      well-defined listing order for machine types · 2709f263
      Laszlo Ersek 提交于
      Commit 261747f1 ("vl: Use MachineClass instead of global QEMUMachine
      list") broke the ordering of the machine types in the user-visible output
      of
      
        qemu-system-XXXX -M \?
      
      This occurred because registration was rebased from a manually maintained
      linked list to GLib hash tables:
      
        qemu_register_machine()
          type_register()
            type_register_internal()
              type_table_add()
                g_hash_table_insert()
      
      and because the listing was rebased accordingly, from the traversal of the
      list to the traversal of the hash table (rendered as an ad-hoc list):
      
        machine_parse()
          object_class_get_list(TYPE_MACHINE)
            object_class_foreach()
              g_hash_table_foreach()
      
      The current order is a "random" one, for practical purposes, which is
      annoying for users.
      
      Introduce new members QEMUMachine.family and MachineClass.family, allowing
      machine types to be "clustered". Introduce a comparator function that
      establishes a total ordering between machine types, ordering machine types
      in the same family next to each other. In machine_parse(), list the
      supported machine types sorted with the comparator function.
      
      The comparator function:
      - sorts whole families before standalone machine types,
      - sorts whole families between each other in alphabetically increasing
        order,
      - sorts machine types inside the same family in alphabetically decreasing
        order,
      - sorts standalone machine types between each other in alphabetically
        increasing order.
      
      After this patch, all machine types are considered standalone, and
      accordingly, the output is alphabetically ascending. This will be refined
      in the following patches.

      In case of -daemonize, we write non-zero to the daemon
      pipe only if pidfile creation failed, so the parent will
      report error about pidfile problem.  There's no need to
      make special case for this, since all other errors are
      reported by the child just fine.  Let the parent report
      error and simplify logic in os_daemonize().
      
      This way, we don't need os_pidfile_error() function, since
      it only prints error now, so put the error reporting printf
      into the only place where qemu_create_pidfile() is called,
      in vl.c.
      
      While at it, fix wrong indentation in os_daemonize().

      pc/vl: Add units-per-default-bus property · 16026518
      John Snow 提交于
      This patch adds the 'units_per_default_bus' property which
      allows individual boards to declare their desired
      index => (bus,unit) mapping for their default HBA, so that
      boards such as Q35 can specify that its default if_ide HBA,
      AHCI, only accepts one unit per bus.
      
      This property only overrides the mapping for drives matching
      the block_default_type interface.
      
      This patch also adds this property to *all* past and present
      Q35 machine types. This retroactive addition is justified
      because the previous erroneous index=>(bus,unit) mappings
      caused by lack of such a property were not utilized due to
      lack of initialization code in the Q35 init routine.
      
      Further, semantically, the Q35 board type has always had the
      property that its default HBA, AHCI, only accepts one unit per
      bus. The new code added to add devices to drives relies upon
      the accuracy of this mapping. Thus, the property is applied
      retroactively to reduce complexity of allowing IDE HBAs with
      different units per bus.
      
      Examples:
      
      Prior to this patch, all IDE HBAs were assumed to use 2 units
      per bus (Master, Slave). When using Q35 and AHCI, however, we
      only allow one unit per bus.
      
      -hdb foo.qcow2 would become index=1, or bus=0,unit=1.
      -hdd foo.qcow2 would become index=3, or bus=1,unit=1.
      -drive file=foo.qcow2,index=5 becomes bus=2,unit=1.
      
      These are invalid for AHCI. They now become, under Q35 only:
      
      -hdb foo.qcow2 --> index=1, bus=1, unit=0.
      -hdd foo.qcow2 --> index=3, bus=3, unit=0.
      -drive file=foo.qcow2,index=5 --> bus=5,unit=0.
      
      The mapping is adjusted based on the fact that the default IF
      for the Q35 machine type is IF_IDE, and units-per-default-bus
      overrides the IDE mapping from its default of 2 units per bus
      to just 1 unit per bus.

      blockdev: Orphaned drive search · a66c9dc7
      John Snow 提交于
      When users use command line options like -hda, -cdrom,
      or even -drive if=ide, it is up to the board initialization
      routines to pick up these drives and create backing
      devices for them.
      
      Some boards, like Q35, have not been doing this.
      However, there is no warning explaining why certain
      drive specifications are just silently ignored,
      so this function adds a check to print some warnings
      to assist users in debugging these sorts of issues
      in the future.
      
      This patch will not warn about drives added with if_none,
      for which it is not possible to tell in advance if
      the omission of a backing device is an issue.
      
      A warning in these cases is considered appropriate.

      async: aio_context_new(): Handle event_notifier_init failure · 2f78e491
      Chrysostomos Nanakos 提交于
      On a system with a low limit of open files the initialization
      of the event notifier could fail and QEMU exits without printing any
      error information to the user.
      
      The problem can be easily reproduced by enforcing a low limit of open
      files and start QEMU with enough I/O threads to hit this limit.
      
      The same problem raises, without the creation of I/O threads, while
      QEMU initializes the main event loop by enforcing an even lower limit of
      open files.
      
      This commit adds an error message on failure:
      
       # qemu [...] -object iothread,id=iothread0 -object iothread,id=iothread1
       qemu: Failed to initialize event notifier: Too many open files in system
