2013-02-21vga: fix byteswapping.Gerd Hoffmann4-13/+13
In case host and guest endianness differ the vga code first creates a shared surface (using qemu_create_displaysurface_from), then goes patch the surface format to indicate that the bytes must be swapped. The switch to pixman broke that hack as the format patching isn't propagated into the pixman image, so ui code using the pixman image directly (such as vnc) uses the wrong format. Fix that by adding a byteswap parameter to qemu_create_displaysurface_from, so we'll use the correct format when creating the surface (and the pixman image) and don't have to patch the format afterwards.

2013-02-21ppc: fix bamboo >256MB RAM initialization in hw/ppc4xx_devs.cAlin Tomescu1-1/+1
I was trying to launch a PowerPC "bamboo" machine with more than 256MB of RAM with qemu-system-ppc -M bamboo -kernel $kernel -initrd $ramdisk -m 512, but QEMU would just hang. However, when I used -m 256, the machine would boot. I looked through the code in hw/ and it seems there is an error when the RAM memory is setup (if my understanding is correct). After patching it, the machine launched and booted successfully with 512MB of RAM. Signed-off-by: Alin Tomescu <tomescu.alin@gmail.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

Leave the core usb devices (usb hub, tablet, mouse, keyboard) enabled unconditionally. Make the other ones configurable. Exceptions: - bluetooth: not qdevified yet, has a vl.c dependency because of that, thus disabling isn't as easy as not linking the object file. - smardcard: ccid-card-emulated depends on that one *and* CONFIG_SMARTCARD_NSS.

Unfortunately, we have treated to I/O interruption word as if it contained the bitmask as well, which went unnoticed so far as - (queued-for-next) kvm made the same mistake, and - Linux guest kernels don't check the isc value in the I/O interruption word for subchannel interrupts.

Atmel, SST and Intel/Numonyx serial flash tend to power up with the software protection bits set. And thus the new m25p80.c in linux kernel would always tries to use WREN(0x06) + WRSR(0x01) to turn-off the protection. The WEL(0x02) of status register is supposed to be cleared after WRSR(0x01). There are also some drivers (i.e mine for RTOSes) would check the WEL(0x02) in status register to make sure the protection is correctly turned off.

2013-02-04acpi_piix4: fix segfault migrating from 1.2Michael Roth1-2/+2
b0b873a07872f7ab7f66f259c73fb9dd42aa66a9 bumped the vmstate version and introduced an old-style load function to handle migration from prior (<= 1.2) versions. The load function passes the top-level PIIX4PMState pointer to vmstate_load_state() to handle nested structs for APMState and pci_status, which leads to corruption of the top-level PIIX4PMState, since pointers to the nested structs are expected. A segfault can be fairly reliably triggered by migrating from 1.2 and issuing a reset, which will trigger a number of QOM operations which rely on the now corrupted ObjectClass/Object members. Fix this by passing in the expected pointers for vmstate_load_state().

2013-02-01qdev: drop extra references at creation timePaolo Bonzini2-4/+6
qdev_free and qbus_free have to do unparent+unref, because nobody else drops the initial reference (the one included by object_initialize) before them. For device_init_func and do_device_add, this is trivially correct, since the DeviceState goes out of scope. For qdev_create, qdev_try_create and qbus_init, it is a bit more tricky. What we are doing here is just assuming that the caller knows what it's doing, and won't call qdev_free/qbus_free while the device is still there. This is a pretty reasonable assumption and (behind the scenes) is also what GObject/GTK does. GTK actually has a "floating reference" that goes away as soon as the caller does gtk_container_add or something like that, but in the end qbus_init and qdev_try_create are already adding the new object to its qdev parent! So in the end the two solutions are the same. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2013-02-01qdev: move unrealization of devices from finalize to unparentPaolo Bonzini1-18/+17
Similarly, a bus holds a reference back to the device, and this will prevent the device from going away as soon as this reference is counted properly. To avoid this, move the unrealization of devices to the unparent callback. This includes recursively unparenting all the buses and (after the previous patch) the devices on those buses, which ensures that the web of references completely disappears for all devices that reside (in the qdev tree) below the one being unplugged. After this patch, the qdev tree and the bus<->child relationship is defined as "A is above B, iff unplugging A will automatically unplug B".
