2016-06-09cpu-exec: Rename cpu_resume_from_signal() to cpu_loop_exit_noexc()Peter Maydell
The function cpu_resume_from_signal() is now always called with a NULL puc argument, and is rather misnamed since it is never called from a signal handler. It is essentially forcing an exit to the top level cpu loop but without raising any exception, so rename it to cpu_loop_exit_noexc() and drop the useless unused argument.

2016-06-07virtio-blk: Remove op blocker for dataplaneFam Zheng
Block layer is prepared to unspecialize dataplane, an evidence is this almost complete list of unblocked operations. It has all types except two (actually three if DATAPLANE itself counts but blockdev.c makes sure attaching twice is not possible): MIRROR_TARGET and BACKUP_TARGET. blockdev-mirror refuses to start if target is attached, so the first is not a problem. By removing BACKUP_TARGET, blockdev-backup will become permissive to write to a virtio-blk dataplane disk, but that is not worse than non-dataplane given the latter is already possible. In either case, blockdev.c always checks the target and source are on the same AioContext, or bring them together if possible. Signed-off-by: Fam Zheng <famz@redhat.com> Acked-by: Michael S.

2016-06-07virtio: move bi-endian target support to a single locationGreg Kurz
Paolo's recent cpu.h cleanups broke legacy virtio for ppc64 LE guests (and arm BE guests as well, even if I have not verified that). Especially, commit "33c11879fd42 qemu-common: push cpu.h inclusion out of qemu-common.h" has the side-effect of silently hiding the TARGET_IS_BIENDIAN macro from the virtio memory accessors, and thus fully disabling support of endian changing targets. To be sure this cannot happen again, let's gather all the bi-endian bits where they belong in include/hw/virtio/virtio-access.h. The changes in hw/virtio/vhost.c are safe because vhost_needs_vring_endian() is not called on a hot path and non bi-endian targets will return false anyway. While here, also rename TARGET_IS_BIENDIAN to be more precise: it is only for legacy virtio and bi-endian guests. Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com> Reviewed-by: Michael S.

Also as 'TCPA' is allocated 0 filled, there is no point in calculating always 0 log_area_start_address and set tcpa->log_area_start_address to it since the field should always point to start of ACPI_BUILD_TPMLOG_FILE.

And find blob by name looking up allocated file entries inside of bios_linker_add_foo() commands.

2016-06-07pc: acpi: cpuhp-legacy: switch ProcessorID to possible_cpus idxIgor Mammedov
In legacy cpu-hotplug ProcessorID == APIC ID is used in MADT and cpu-hotplug AML. It was fine as both are 8bit and unique. Spec depricated Processor() with corresponding ProcessorID and advises to use Device() and UID instead of it. However UID is just 32bit and it can't fit ARM's arch_id(MPIDR) which is 64bit. Also in case of sparse arch_id() distribution, managment/lookup of maps by arch_id(APIC ID/MPIDR) becomes complex and expensive. In preparation to common CPU hotplug with ARM and to simplify lookup in possible_cpus[] map switch ProcessorID to possible_cpus index in MADT. Legacy cpu-hotplug considerations: HW interface of it is APIC ID based bitmask so it's impossible to change, also CPON package in AML also APIC ID based as well all the methods. To avoid massive rewrite of AML keep is so and just break assumption that ProcessorID == APIC ID, ammending CPU_MAT_METHOD to accept APIC ID and possible_cpus index, it needs them both to patch MADT entry template. Also switch to possible_cpus index Processor(ProcessorID) AML. That way changes to MADT/AML are minimal and kept inside AML/MADT not affecting external interfaces.
