2012-03-19xen mapcache: check if memory region has moved.Anthony PERARD
This patch changes the xen_map_cache behavior. Before trying to map a guest addr, mapcache will look into the list of range of address that have been moved (physmap/set_memory). There is currently one memory space like this, the vram, "moved" from were it's allocated to were the guest will look into. This help to have a succefull migration.

2012-03-19Introduce "xen-save-devices-state"Stefano Stabellini
- add an "is_ram" flag to SaveStateEntry; - register_savevm_live sets is_ram for live_savevm devices; - introduce a "xen-save-devices-state" QAPI command that can be used to save the state of all devices, but not the RAM or the block devices of the VM. Changes in v8: - rename save-devices-state to xen-save-devices-state. Changes in v7: - rename save_devices to save-devices-state. Changes in v6: - remove the is_ram parameter from register_savevm_live and sets is_ram if the device is a live_savevm device; - introduce save_devices as a QAPI command, write a better description for it; - fix CODING_STYLE; - introduce a new doc to explain the save format used by save_devices.

In cpu_physical_memory_rw, a change has been introduced and qemu_get_ram_ptr is no longuer called with the ram addr we want to access, but only with the section address. This patch fixes this. (All other call to qemu_get_ram_ptr are already called with the right address.) This patch fixes Xen guest.

2012-03-19scsi: copy serial number into VPD page 0x83Paolo Bonzini
Currently QEMU passes the qdev device id to the guest in an ASCII-string designator in page 0x83. While this is fine, it does not match what real hardware does; usually the ASCII-string designator there hosts another copy of the serial number (there can be other designators, for example with a world-wide name). Do the same for QEMU SCSI disks. ATAPI does not support VPD pages, so it does not matter there. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-03-19scsi-cd: check ready condition before processing several commandsPaolo Bonzini
This commit is more or less obvious. What it caused is less obvious: SCSI CD drives failed to eject under Linux, though for example the "change" command worked okay. This happens because of the autoclose option in the Linux CD-ROM driver. The actual chain of events is quite complex and somehow involves udev helpers; the actual command that matters is READ TOC, though honestly it's not really clear to me how because it should always be invoked after autoclose, not before.

2012-03-19spice: fix broken initializationAlon Levy
Commit 1b71f7c14fab6f00c2680d4489fbee7baf796e4f moved MODULE_INIT_QOM to way before MODULE_INIT_MACHINE, thereby breaking assumptions made in spice-core.c which registered both a type initializer and a machine intializer. This fix removes the type registration, and replaces it with calling qemu_spice_init in vl.c after command line parsing (second pass) is done, and after timers are armed, required by spice server.

2012-03-19vnc: Fix packed boolean struct membersStefan Weil
This patch fixes warnings reported by splint: For variables which are packed in a single bit, a signed data type like 'int' does not make much sense. There is no obvious reason why the two values should be packed, so I removed the packing and changed the data type to bool because both are used as boolean values. v2: Some versions of gcc complain after this modification, for example gcc (Debian 4.4.5-8) 4.4.5): ui/vnc-auth-sasl.c: In function ‘vnc_sasl_client_cleanup’: ui/vnc-auth-sasl.c:34: error: suggest parentheses around assignment used as truth value Obviously, the compiler does not like code which does bool = unsigned = bool = 0 Splitting that code in three statements works.

2012-03-19memory: check for watchpoints when getting code ram_addrAvi Kivity

2012-03-19exec: fix write tlb entry misused as iotlbAvi Kivity
A couple of code paths check the lower bits of CPUTLBEntry::addr_write against io_mem_ram as a way of looking for a dirty RAM page. This works by accident since the value is zero, which matches all clear bits for TLB_INVALID, TLB_MMIO, and TLB_NOTDIRTY (indicating dirty RAM). Make it work by design by checking for the proper bits. Signed-off-by: Avi Kivity <avi@redhat.com>

2012-03-17w64: Fix data type of next_tb and tcg_qemu_tb_execStefan Weil
next_tb is the numeric value of a tcg target (= QEMU host) address. Using tcg_target_ulong instead of unsigned long shows this and makes the code portable for hosts with an unusual size of long (w64). The type cast '(long)(next_tb & ~3)' was not needed (casting unsigned long to long does not change the bits, and nor does casting long to pointer for most (= all non w64) hosts. It is removed here. Macro or function tcg_qemu_tb_exec is used to set next_tb. The function also returns next_tb. Therefore tcg_qemu_tb_exec must return a tcg_target_ulong.
