This commit introduces utility functions for the creation and deallocation
of QemuDmaBuf instances. Additionally, it updates all relevant sections
of the codebase to utilize these new utility functions.
v7: remove prefix, "dpy_gl_" from all helpers
qemu_dmabuf_free() returns without doing anything if input is null
(Daniel P. Berrangé <berrange@redhat.com>)
call G_DEFINE_AUTOPTR_CLEANUP_FUNC for qemu_dmabuf_free()
(Daniel P. Berrangé <berrange@redhat.com>)
v8: Introduction of helpers was removed as those were already added
by the previous commit
v9: set dmabuf->allow_fences to 'true' when dmabuf is created in
virtio_gpu_create_dmabuf()/virtio-gpu-udmabuf.c
removed unnecessary spaces were accidently added in the patch,
'ui/console: Use qemu_dmabuf_new() a...'
v11: Calling qemu_dmabuf_close was removed as closing dmabuf->fd will be
done in qemu_dmabuf_free anyway.
(Daniel P. Berrangé <berrange@redhat.com>)
v12: --- Calling qemu_dmabuf_close separately as qemu_dmabuf_free doesn't
do it.
--- 'dmabuf' is now allocated space so it should be freed at the end of
dbus_scanout_texture
v13: --- Immediately free dmabuf after it is released to prevent possible
leaking of the ptr
(Marc-André Lureau <marcandre.lureau@redhat.com>)
--- Use g_autoptr macro to define *dmabuf for auto clean up instead of
calling qemu_dmabuf_free
(Marc-André Lureau <marcandre.lureau@redhat.com>)
v14: --- (vhost-user-gpu) Change qemu_dmabuf_free back to g_clear_pointer
as it was done because of some misunderstanding (v13).
--- (vhost-user-gpu) g->dmabuf[m->scanout_id] needs to be set to NULL
to prevent freed dmabuf to be accessed again in case if(fd==-1)break;
happens (before new dmabuf is allocated). Otherwise, it would cause
invalid memory access when the same function is executed. Also NULL
check should be done before qemu_dmabuf_close (it asserts dmabuf!=NULL.).
