backends: Add TPM files into their own directory

2020-06-19T11:24:42+00:00

As we will have various TPM backend files, it is cleaner to use a single directory. Suggested-by: Stefan Berger Signed-off-by: Philippe Mathieu-Daudé Reviewed-by: Stefan Berger Message-id: 20200612085444.8362-3-philmd@redhat.com Signed-off-by: Stefan Berger

Add dbus-vmstate object

2020-01-06T14:41:32+00:00

When instantiated, this object will connect to the given D-Bus bus "addr". During migration, it will take/restore the data from org.qemu.VMState1 instances. See documentation for details. Signed-off-by: Marc-André Lureau Reviewed-by: Daniel P. Berrangé

rng-builtin: add an RNG backend that uses qemu_guest_getrandom()

2019-09-04T10:32:51+00:00

Add a new RNG backend using QEMU builtin getrandom function. It can be created and used with something like: ... -object rng-builtin,id=rng0 -device virtio-rng,rng=rng0 ... Signed-off-by: Laurent Vivier Message-Id: <20190820160615.14616-2-lvivier@redhat.com>

Add vhost-user-backend

2019-05-10T10:48:35+00:00

Create a vhost-user-backend object that holds a connection to a vhost-user backend (or "slave" process) and can be referenced from virtio devices that support it. See later patches for input & gpu usage. Note: a previous iteration of this object made it user-creatable, and allowed managed sub-process spawning, but that has been dropped for now.

vhost: restrict Linux dependency to kernel vhost

2019-02-21T17:28:01+00:00

vhost-user does not depend on Linux; it can run on any POSIX system. Restrict vhost-kernel to Linux in hw/virtio/vhost-backend.c, everything else can be compiled on all POSIX systems.

hostmem-file: make available memory-backend-file on POSIX-based hosts

2018-10-02T17:09:13+00:00

Before this change, memory-backend-file object is valid for Linux hosts only because hostmem-file.c is compiled only on Linux hosts. However, other POSIX-based hosts (such as macOS) can support memory-backend-file object in the same way as on Linux hosts. This patch makes hostmem-file.c and related functions to be compiled on all POSIX-based hosts to make available memory-backend-file on them.

Add memfd based hostmem

2018-02-07T13:09:25+00:00

Add a new memory backend, similar to hostmem-file, except that it doesn't need to create files. It also enforces memory sealing. This backend is mainly useful for sharing the memory with other processes. Note that Linux supports transparent huge-pages of shmem/memfd memory since 4.8. It is relatively easier to set up THP than a dedicate hugepage mount point by using "madvise" in /sys/kernel/mm/transparent_hugepage/shmem_enabled. Since 4.14, memfd allows to set hugetlb requirement explicitly. Pending for merge in 4.16 is memfd sealing support for hugetlb backed memory.
