8348800871 dm: virtio_rnd: use delayed blocking IO to make virtio_rnd works on Linux based SOS
Randomness sourced from /dev/random which does not block
once it has been seeded at bootup and you will always get
something when you read from that file. This is true on
Freebsd but unfortunately things are not the same on Linux.
Most cases, you can't read anything from /dev/random especially
on current acrn platform which lacking random events.
virtio_rnd inherted from freebsd doesn't work anymore.

This patch makes virtio_rnd working on Linux based SOS. It uses
blocking IO to sevice the front-end random driver and delays the
read operation into a new thread to avoid blocking the main
notify thread.

    writeback   | yes
    writethru   | no

2. To toggle cache mode, run below command in guest OS:

f4fcf5d6eb dm: virtio: remove hv_caps from virtio_ops
currently, each virtio device has their own virtio_ops implementation.
Take virtio-blk for example:

static struct virtio_ops virtio_blk_ops = {
        "virtio_blk",
        1,
        sizeof(struct virtio_blk_config),
        virtio_blk_reset,
        virtio_blk_notify,
        virtio_blk_cfgread,
        virtio_blk_cfgwrite,
        NULL,
        NULL,
        VIRTIO_BLK_S_HOSTCAPS,
};

If start DM with two virtio-blk, this global variable will be
assigined to two virtio-blk instances. Changing hv_caps for one
instance will affect others. But different instances may need
different capabilities.

To support this requirement, we suggest to move hv_caps to
virtio_base structure, and each instance can return their own
capabilities.

c492a14e53 hv: pirq: do not indicate priority when allocate vector
It's not necessary to specify priority for dynamic allocated vector, because
nested irq is not supported on HV, and irq of any priority would cause VM exit.

This commit makes the following changes:
 - remove the argument indicating priority in struct irq_request_info and
   following functions:
    ptdev_activate_entry()
    find_available_vector()
    irq_desc_alloc_vector()
    normal_register_handler()
 - change the macro of vector ranges:
    VECTOR_DYNAMIC_START/END for dynamically allocable vectors;
    VECTOR_FIXED_START/END for fixed allocated vectors, such as vector for
    timer etc.

229bf32eb5 hv:Refine destroy_secure_world API
-- add clear trusty memory flag
  In some cases such as UOS power off or UOS full reset,
  need to clear trusty memory,no need to clear memory such as
  UOS S3 or UOS system reset,then add a flag to distinguish it
  when destroy secure world.
-- Restore trusty memory to guest normal world.
-- Moved free trusty EPT inside destroy_secure_world
  In some cases such as UOS S3 or UOS system reset,
  only need to free trusty EPT, this patch move free
  trusty EPT inside destroy_secure_world.
  Because PD/PT are shared in both secure world's EPT
  and normal world's EPT,before freeing trusty EPT,
  it will memset all PDPTEs except trusty memory,
  then call 'free_ept_mem', it can only free trusty EPT,
  and does't affect shared normal world EPT.

v2-->v3:
    -- Used new mmu api ept_mr_add when restore trusty memory
       to SOS and normal world
    -- Dropped this patch "Removed reverted page tables for trusty memory"
       because map_mem will be removed in future
       It will have a patch, need to update this api(ept_mr_add),
       it will not create inverted page tables for trusty memory.

v1-->v2:
   -- free trusty ept
       still use free_ept_mem, not add a new api,but need to
       memset pdptes except trusty memory

2fc3bdec40 HV: trusty: new hypercall to save/restore context of secure world
New field in VM's structure:
    sworld_snapshot: save cpu_context of secure world.

New hypercall: HC_SAVE_RESTORE_SWORLD_CTX
    In UOS S3 suspend path: trusty kernel driver will call this hypercall
    to require Hypervisor save context of secure world.
    In UOS S3 resume path: virtual firmware will call this hypercall to
    require Hypervisor restore context of secure world.

New bit in secure_world_control.flag:
    ctx_saved: indicate whether cpu_context of secure world is saved.

The security information will not pass to HV through Hypercall,
so remove the unused HC_GET_SEC_INFO.

b5b769f45a HV: trusty: refine secure_world_control
Define Bitmap flag to indicate secure world's state:
    supported: 0(not supported), 1(supported)
    active:    0(inactive), 1(active)

Refine secure_world_memory:
    base_gpa_in_sos: base_gpa from SOS's view
    base_gpa_in_uos: base_gpa from UOS's view, this is the original base_gpa
                     allocated by bootloader.
    Recording above GPA is for usage of trusty EPT destroy and re-create.
    There is an assumption: the secure world's memory address is contiguous
    in both SOS and physical side.
