2014-06-29hw/arm/virt: Provide PL031 RTCPeter Maydell
UEFI mandates that the platform must include an RTC, so provide one in 'virt', using the PL031. This is also useful for directly booting Linux kernels which would otherwise have to run ntpdate.

2014-06-29vhost-net: disable when cross-endianGreg Kurz
As of today, vhost assumes guest and host have the same endianness. This is definitely not compatible with modern PPC64 and ARM that can change endianness at runtime.

2014-06-29virtio: memory accessors for endian-ambivalent targetsGreg Kurz
This is the virtio-access.h header file taken from Rusty's "endian-ambivalent targets using legacy virtio" patch. It introduces helpers that should be used when accessing vring data or by drivers for data that contains headers. The virtio config space is also target endian, but the current code already handles that with the virtio_is_big_endian() helper. There is no obvious benefit at using the virtio accessors in this case. Now we have two distinct paths: a fast inline one for fixed endian targets, and a slow out-of-line one for targets that define the new TARGET_IS_BIENDIAN macro.

2014-06-29virtio: add endian-ambivalent support to VirtIODeviceGreg Kurz
Some CPU families can dynamically change their endianness. This means we can have little endian ppc or big endian arm guests for example. This has an impact on legacy virtio data structures since they are target endian. We hence introduce a new property to track the endianness of each virtio device. It is reasonnably assumed that endianness won't change while the device is in use : we hence capture the device endianness when it gets reset. We migrate this property in a subsection, after the device descriptor. This means the load code must not rely on it until it is restored. As a consequence, the vring sanity checks had to be moved after the call to vmstate_load_state(). We enforce paranoia by poisoning the property at the begining of virtio_load().

2014-06-29cpu: introduce CPUClass::virtio_is_big_endian()Greg Kurz
If we want to support targets that can change endianness (modern PPC and ARM for the moment), we need to add a per-CPU class method to be called from the virtio code. The virtio_ prefix in the name is a hint for people to avoid misusage (aka. anywhere but from the virtio code). The default behaviour is to return the compile-time default target endianness.

2014-06-29exec: introduce target_words_bigendian() helperGreg Kurz
We currently have a virtio_is_big_endian() helper that provides the target endianness to the virtio code. As of today, the helper returns a fixed compile-time value. Of course, this will have to change if we want to support target endianness changes at run-time. Let's move the TARGET_WORDS_BIGENDIAN bits out to a new helper and have virtio_is_big_endian() implemented on top of it. This patch doesn't change any functionality.

2014-06-29virtio: add subsections to the migration streamGreg Kurz
There is a need to add some more fields to VirtIODevice that should be migrated (broken status, endianness). The problem is that we do not want to break compatibility while adding a new feature... This issue has been addressed in the generic VMState code with the use of optional subsections. As a *temporary* alternative to port the whole virtio migration code to VMState, this patch mimics a similar subsectionning ability for virtio, using the VMState code. Since each virtio device is streamed in its own section, the idea is to stream subsections between the end of the device section and the start of the next sections. This allows an older QEMU to complain and exit when fed with subsections: Unknown savevm section type 5 load of migration failed Suggested-by: Alexander Graf <agraf@suse.de> Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com> Reviewed-by: Alexander Graf <agraf@suse.de> Reviewed-by: Michael S.

2014-06-29vhost-user: fix regions provied with VHOST_USER_SET_MEM_TABLE messageDamjan Marion
Old code was affected by memory gaps which resulted in buffer pointers pointing to address outside of the mapped regions. Here we are introducing following changes: - new function qemu_get_ram_block_host_ptr() returns host pointer to the ram block, it is needed to calculate offset of specific region in the host memory - new field mmap_offset is added to the VhostUserMemoryRegion. It contains offset where specific region starts in the mapped memory. As there is stil no wider adoption of vhost-user agreement was made that we will not bump version number due to this change - other fileds in VhostUserMemoryRegion struct are not changed, as they are all needed for usermode app implementation - region data is not taken from ram_list.blocks anymore, instead we use region data which is alredy calculated for use in vhost-net - Now multiple regions can have same FD and user applicaton can call mmap() multiple times with the same FD but with different offset (user needs to take care for offset page alignment) Signed-off-by: Damjan Marion <damarion@cisco.com> Acked-by: Michael S.

2014-06-29pc: Move q35 compat props to PC_COMPAT_*Eduardo Habkost
For each compat property on PC_Q35_COMPAT_*, there are only two possibilities: * If the device is never instantiated when using a machine other than pc-q35, then the compat property can be safely added to PC_COMPAT_*; * If the device can be instantiated when using a machine other than pc-q35, that means the other machines also need the compat property to be set. That means we don't need separate PC_Q35_COMPAT_* macros at all, today. The hpet.hpet-intcap case is interesting: piix and q35 do have something that emulates different defaults, but the machine-specific default is applied _after_ compat_props are applied, by simply checking if the property is zero (which is the real default on the hpet code). The hpet.hpet-intcap=0x4 compat property can (should?) be applied to piix too, because 0x4 was the default on both piix and q35 before the hpet-intcap property was introduced. Now, if one day we change the default HPET intcap on one of the PC machine-types again, we may want to introduce PC_{Q35,I440FX}_COMPAT macros. But while we don't need that, we can keep the code simple.

2014-06-29linux-user: allow NULL tv argument for settimeofdayPaul Burton
The tv argument to the settimeofday syscall is allowed to be NULL, if the program only wishes to provide the timezone. QEMU previously returned -EFAULT when tv was NULL. Instead, execute the syscall & provide NULL to the kernel as the target program expected. Signed-off-by: Paul Burton <paul@archlinuxmips.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
2014-06-29linux-user: respect timezone for settimeofdayPaul Burton
The settimeofday syscall accepts a tz argument indicating the desired timezone to the kernel. QEMU previously ignored any argument provided by the target program & always passed NULL to the kernel. Instead, translate the argument & pass along the data userland provided. Although this argument is described by the settimeofday man page as obsolete, it is used by systemd as of version 213.

2014-06-29linux-user: support strace of epoll_create1Paul Burton
Add the epoll_create1 syscall to strace.list in order to display that syscall when it occurs, rather than a message about the syscall being unknown despite QEMU already implementing support for it.
