| * | uninorth: remove token register from uninorth deviceMark Cave-Ayland2018-06-121-1/+3
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | >From observation of various OS sources it can be seen that the token register introduced in 4e46dcdbd3 "PPC: Newworld: Add uninorth token register" is not required, since the only register currently implemented is the uninorth hardware version which is read-only. Remove the token register implementation and instead return the uninorth version corresponding to the hardware.

This will overlap the GICR registers value and leave the last GIC_INTERNAL irq's registers out of update. Fix this by skipping the registers banked by GICR. Also for migration compatibility if the migration source (old version qemu) doesn't send gicd_no_migration_shift_bug = 1 to destination, then we shift the data of PPI to get the right data for SPI.

Priority management and interrupt acknowledgment is also controlled by MMIO in the presenter sub-engine. These MMIO regions are exposed to guests in QEMU with a set of 'ram device' memory mappings, similarly to VFIO, and the VMAs are populated dynamically with the appropriate pages using a fault handler. But, these regions are an issue for migration. We need to discard the associated RAMBlocks from the RAM state on the source VM and let the destination VM rebuild the memory mappings on the new host in the post_load() operation just before resuming the system. To achieve this goal, the following introduces a new RAMBlock flag RAM_MIGRATABLE which is updated in the vmstate_register_ram() and vmstate_unregister_ram() routines. This flag is then used by the migration to identify RAMBlocks to discard on the source. Some checks are also performed on the destination to make sure nothing invalid was sent. This change impacts the boston, malta and jazz mips boards for which migration compatibility is broken.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces VHOST_USER_PROTOCOL_F_HOST_NOTIFIER. With this feature negotiated, vhost-user backend can register memory region based host notifiers. And it will allow the guest driver in the VM to notify the hardware accelerator at the vhost-user backend directly. Signed-off-by: Tiwei Bie <tiwei.bie@intel.com> Reviewed-by: Michael S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When multi queue is enabled e.g. for a virtio-net device, each queue pair will have a vhost_dev, and the only thing shared between vhost devs currently is the chardev. This patch introduces a vhost-user state structure which will be shared by all vhost devs of the same virtio device. Signed-off-by: Tiwei Bie <tiwei.bie@intel.com> Signed-off-by: Michael S.

This would make libvirt set the corresponding capability and then trigger failure during guest startup. This patch moves the code regarding seccomp command line options to qemu-seccomp.c file and wraps qemu_opts_foreach finding sandbox option with CONFIG_SECCOMP. Because parse_sandbox() is moved into qemu-seccomp.c file, change seccomp_start() to static function.
