2012-05-12vga: disable default VGA if appropriate -device is usedPaolo Bonzini
This is a partial revert of commits a369da5 (vga: improve VGA logic, committed 2012-01-22) and c5bd4f3 (vga: fix -nodefaults -device VGA, 2012-01-24) which broke command-line option parsing in different ways. Since commit a369da5 it has become impossible to specify a VGA device entirely with QemuOpts-enabled options, i.e. without needing an explicit "-vga none". In addition, until commit c5bd4f3 -nodefaults would not disable the device you specified with the legacy "-vga" option, independent of the order. Since commit c5bd4f3 QEMU -nodefaults will override a previous -vga option. I did not reintroduce machine->no_vga. Boards can simply ignore the vga_interface_type variable, and most will indeed do so. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-05-10target-arm/cpu.h: Make cpu_init("nonexistent cpu") return NULLPeter Maydell
The macro definition of cpu_init meant that if cpu_arm_init() returned NULL this wouldn't result in cpu_init() itself returning NULL. This had the effect that "-cpu foo" for some unknown CPU name 'foo' would cause ARM targets to segfault rather than generating a useful error message. Fix this by making cpu_init a simple inline function. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Andreas Färber <afaerber@suse.de>

For targets where TARGET_LONG_BITS != 32, i.e. 64-bit guests, addr_reg is moved to r4. For hosts without TCG_TARGET_CALL_ALIGN_ARGS either data_reg2 or data_reg or a masked version thereof would overwrite r4. Place it in r5 instead, matching TCG_TARGET_CALL_ALIGN_ARGS hosts.

2012-05-08hmp: fix bad value conversion for M typeLuiz Capitulino
The M type converts from megabytes to bytes. However, the value can be negative before the conversion, which will lead to a flawed conversion. For example, this: (qemu) balloon -1000000000000011 (qemu) Just "works", but the value passed by the balloon command will be something else. This patch fixes this problem by requering a positive value before converting. There's really no reason to accept a negative value for the M type.

2012-05-08runstate: introduce suspended stateLuiz Capitulino
QEMU enters in this state when the guest suspends to ram (S3). This is important so that HMP users and QMP clients can know that the guest is suspended. QMP also has an event for this, but events are not reliable and are limited (ie. a client can connect to QEMU after the event has been emitted). Having a different state for S3 brings a new issue, though. Every device that doesn't run when the VM is stopped but wants to run when the VM is suspended has to check for RUN_STATE_SUSPENDED explicitly. This is the case for the keyboard and mouse devices, for example. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com>

2012-05-08user-exec.c: Don't assert on segfaults for non-valid addressesPeter Maydell
h2g() will assert if passed an address that's not a valid guest address, so handle_cpu_signal() needs to check before passing "data address which caused a segfault" to it, since for a misbehaving guest that could be anything. If the address isn't a valid guest address then we can simply skip the attempt to unprotect a guest page which was made read-only to catch self-modifying code. This assertion probably fires more readily now than it used to do because of recent changes to default to reserving guest address space.

2012-05-07qcow2: Limit COW to where it's neededKevin Wolf
This fixes a regression introduced in commit 250196f1. The bug leads to data corruption, found during an Autotest run with a Fedora 8 guest. Consider a write request whose first part is covered by an already allocated cluster, but additional clusters need to be newly allocated. When counting the number of clusters to allocate, the qcow2 code would decide to do COW for all remaining clusters of the write request, even if some of them are already allocated. If during this COW operation another write request is issued that touches the same cluster, it will still refer to the old cluster. When the COW completes, the first request will update the L2 table and the second write request will be lost. Note that the requests need not overlap, it's enough for them to touch the same cluster. This patch ensures that only clusters that really require COW are considered for allocation. In this case any other request writing to the same cluster will be an allocating write and gets serialised.

2012-05-07hw/ac97: Make a bunch of mixer registers read onlyHans de Goede
The Linux ac97 driver tries to see if optional things like video input volume control are available in 2 ways: 1) See if the mute bit is set after reset, if it is no further tests are done 2) If the mute bit is not set it does a write/read test of the mute bit This patch changes our ac97 to conform to what the Linux driver expects, it initializes registers for things which we don't emulate to 0 (so the mute bit is not set) and makes them read only. This causes Linux to now longer show the following (functionless) controls in alsamixer: Master Mono vol + mute 3d Control toggle PCM out pre / post 3d select Surround toggle CD vol + mute Mic vol + mute Mic boost toggle Mic mic1 / mic2 select Video vol + mute Phone vol + mute Beep mono vol + mute Aux vol + mute Mono "output mic" / "mix" select Sigmatel 4 speaker stereo toggle Sigmatel ADC 6Db att toggle Sigmatel DAC 6Db att toggle This patch was also tested with a Windows XP guest and there it also makes a number of functionless mixer controls go away.
