2013-07-04vmport: Disentangle read handler type from portioJan Kiszka1-2/+2
In case the latter may vanish one day, make sure the vmport read handler type will remain unaffected. This is also conceptually cleaner. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2013-07-04pvpanic: initialization cleanupMichael S. Tsirkin1-14/+16
Avoid use of static variables: PC systems initialize pvpanic device through pvpanic_init, so we can simply create the fw_cfg file at that point. This also makes it possible to skip device creation completely if fw_cfg is not there, e.g. for xen - so the ports it reserves are not discoverable by guests. Also, make pvpanic_init void since callers ignore return status anyway.

2013-07-01mac-io: Add escc-legacy memory alias regionAlexander Graf1-0/+47
Mac OS X's debugging serial driver accesses the ESCC through a different register layout, called "escc-legacy". This layout differs from the normal escc register layout purely by the location of the respective registers. This patch adds a memory alias region that takes normal escc registers and maps them into the escc-legacy register space. With this patch applied, a Mac OS X guest successfully emits debug output on the serial port when run with debug parameters set, for example by running: $ qemu-system-ppc -prom-env -'boot-args=-v debug=0x8 io=0xff serial=0x3' \ -cdrom 10.4.iso -boot d Signed-off-by: Alexander Graf <agraf@suse.de>

2013-06-25i.MX31: Fix PRCS bit testStefan Weil1-1/+1
cppcheck detected a condition which was always false. According to the MCIMX31 Reference Manual, the PRCS bits have to be 01 to select the Frequency Pre-Multiplier (FPM). PRCS uses bits 1 and 2, so we have to test for 2.

2013-06-20memory: make section size a 128-bit integerPaolo Bonzini1-2/+2
So far, the size of all regions passed to listeners could fit in 64 bits, because artificial regions (containers and aliases) are eliminated by the memory core, leaving only device regions which have reasonable sizes An IOMMU however cannot be eliminated by the memory core, and may have an artificial size, hence we may need 65 bits to represent its size.

2013-06-12ivshmem: add missing error exit(2)Stefan Hajnoczi1-0/+1
If the user fails to specify 'chardev' or 'shm' then we cannot continue. Exit right away so that we don't invoke shm_open(3) with a NULL pointer. It would be nice to replace exit(1) with error returns in the PCI device .init() function, but leave that for another patch since exit(1) is currently used elsewhere. Spotted by Coverity.

2013-04-30introduce a new qom device to deal with panicked eventHu Tao2-0/+125
pvpanic device is used to send guest panic event from guest to qemu. When guest panic happens, pvpanic device driver will write a event number to IO port 0x505(which is the IO port occupied by pvpanic device, by default). On receiving the event, pvpanic device will pause guest cpu(s), and send a qmp event QEVENT_GUEST_PANICKED.
