Conghui a715a3222b asyncio: refine the setup ioctl
Remove the common interface for sbuf setup, as it is not accept by
kernel side. Instead, use dedicate setup function for asyncio to init
its sbuf.

Zhangwei6 b17b5992c8 dm: change the version format
The version info is mainly used to tell the user when and where the binary is
compiled and built, this will change the dm version format.
The dm follows the format:
major.minor-stable/unstable-remote_branch-acrn-commit_date-commit_id-dirty
(tag-current_commit_id) build by author date.
Compare to the hv version, which is:
major.minor-stable/unstable-remote_branch-acrn-commit_date-commit_id-dirty
DBG/REL(tag-current_commit_id) scenario@board build by author date.
The dm doesn't contain DBG/REL because it's given in configurator-tool
only for hv. also not contain scenario and board info.
e.g.
with tag:
$acrn-dm -v
DM: 3.1-stable-release_3.1-2022-09-27-11:15:42-7fad37e02-dirty(tag: v3.1)

Conghui 0f599e8d56 dm: add a new page for asyncio
asyncio is a new mechanism in ACRN, which is special for these devices
which need high IO performance. ACRN hypervisor would process the IO
request from User VM in an async mode.

Just like the original IOReq shared page, the devicemodel also create a
page for fastio requests. As the asyncio use the ioeventfd, so the
reuqests are handled in kernel, devicemodel only need to provide the
page.

Shiqing Gao cc309bd973 dm: refine the detection of "iasl" utility
At run time (on the *target* machine), acrn-dm depends on "iasl" to build
the ACPI tables for post-launched VMs.

This patch does:
- remove the dependency on ASL_COMPILER, which would only be used at build time
- add a new acrn-dm parameter "--iasl <iasl_compiler_path>"
  If "--iasl <iasl_compiler_path>" is specified as the acrn-dm parameter,
  acrn-dm uses <iasl_compiler_path> as the path to the "iasl" compiler;
  otherwise, "which iasl" is used to detect the "iasl" compiler.

  If "iasl" is not found at run time, refuse to launch the post-launched VM
  and exit directly.

v2 -> v3:
 - use "strlen" rather than "strncmp" to check whether asl_compiler
   has been set or not

v1 -> v2:
 - remove "iasl_param" and "with_iasl_param" to simplify the logic

Conghui 844c6e0bbc remove repetitive erasing for guest memory
The guest memory is allocated through hugetlb. Huge page fault is
triggered by writing a byte to the starting address for each huge page.
In hugetlb_fault(), The physical pages are allocated and *clear*.

So no need to erasing the memory again after hugetlb setup. This will
bring about 130ms (changes with platform) latency for each 1G memory.

Notice: this means we depends on kernel to erase the memory in huge page
fault!

The ACRN-DM uses the explicit hugetlb file to allocate the memory
for guest and the 2M/1G hugetlb can be used. This is based on mounting
hugetlb filesystem.
Now the Linux provides one flexbile memfd mechanism to allocate the memory
and this can make it possible to create the udmabuf for sharing. And the
memfd still can be based on Hugetlb 1G/2M policy. This can bring the below
benefits besides the 1G/2M hugetlb support.
a. memfd is based on anonymous file
b. possible dmabuf mechanism

v2->v3: After completing the mmap for memfd, it will call the ftruncate to
set the desired size and then add the F_SEAL_SEAL flag.

Yonghua Huang b4386566ef dm: fix mevent mutex deadlock issue
'mevent_lmutex' is initialized as default type,
 while attempting to recursively lock on this
 kind of mutext results in undefined behaviour.

 Recursively lock on 'mevent_lmutex' can be detected
 in mevent thread when user tries to trigger system
 reset from user VM, in this case, user VM reboot hang.

 The backtrace for this issue:
  #1 in mevent_qlock () at core/mevent.c:93
  #2 in mevent_delete_even at core/mevent.c:357
    ===>Recursively LOCK
  #3 in mevent_delete_close at core/mevent.c:387
  #4 in acrn_timer_deinit at core/timer.c:106
  #5 in virtio_reset_dev at hw/pci/virtio/virtio.c:171
  #6 in virtio_console_reset at
     hw/pci/virtio/virtio_console.c:196
  #7 in virtio_console_destroy at
    hw/pci/virtio/virtio_console.c:1015
  #8 in virtio_console_teardown_backend at
    hw/pci/virtio/virtio_console.c:1042
  #9 in mevent_drain_del_list () at
    core/mevent.c:348 ===> 1st LOCK
  #10 in mevent_dispatch () at core/mevent.c:472
  #11 in main at core/main.c:1110

  So the root cause is:
  mevent_mutex lock is recursively locked by mevent thread
  itself (#9 for this first lock and #2 for recursively lock),
  which is not allowed for mutex with default attribute.

  This patch changes the mutex type of 'mevent_lmutex'
  from default to "PTHREAD_MUTEX_RECURSIVE", because
  recrusively lock shall be allowed as user of mevent
  may call mevent functions (where mutex lock maybe required)
  in teardown callbacks.

fix bug: if PTM-CAP device, like TSN in multi-hostbridge could cause
acrn-dm crash.

original PTM PCI code has not handled multi-hostbridge case, and just
handled hostbridge (00:00.0) case.

this patch calls PCI access API to handle PTM-CAP device/bridge
(root port) structure, to avoid scan PCI hierarchical.

Chenli Wei 8594d15d0c dm:change mac_seed to virtio-net sub-parameter
As a parameter of acrn-dm,the mac_seed is only used for virtio-net.

So this patch change it to the sub-parameter of virtio-net.

Yuanyuan Zhao 940b78d42f dm: remove short version of dm dynamic param `-W`
Rename '--virtio_msix' to '--virtio_msi' for this param
means 'force virtio to use singel-vector MSI'.

`-W` is the short version of `--virtio_msi`. But it's
confusing that `-W` and `--virtio_msi` are irrelevant literally.
So remove the short version `W` to prompt user friendliness.

Yonghua Huang 6bf70e3e35 dm: add ssram support for user VM
Hook ssram init && de-init functions to vdev
 devices lifecycle management:

 1) initialize ssram when vdev devices
    are initialized.

 2) de-initialize ssram when vdev devices
    are reset or destroyed.

 notes:
 ssram configuration data can be released only when
 user VM shutdown, hence it can't be done in deinit_vssram().

  - VM reboot:
    do deinit_vssram() only.

  - VM shutdown:
    do both deinit_vssram() and clean_vssram_config().

Yonghua Huang 28713b3e3e dm: parse bootargs of vssram regions
1) With this patch, '--ssram' option is updated to enable
    vSSRAM feature support for ACRN user VMs.

   '--ssram' argument of Device Model shall follow below format:
	--ssram {Ln,vcpu=vcpu_set,size=nK|M;}
   example:
    --ssram L2,vcpu=0,1,size=4K;L2,vcpu=2,3,size=1M;L3,vcpu=all,size=2M

 2) define data structure and variable
    to store the configuration data for later processing.

 3) add new API to cleanup configuration data when VM shutdown.

virtual RTCT will be created on TCC driver interface, instead of
  pass-through native RTCT to ACRN user VMs.

  this patch removes dependency on native RTCT table:
   - rename build_vrtct() function to init_ssram()
     and minor changes inside.
   - drop function create_and_inject_vrtct()
   - add one API to get virtual RTCT table.
   - rename variable 'pt_rtct' to 'ssram'

Yuanyuan Zhao da0d24326e dm: replace UUID with vmname.
The UUID has several usages before:
1, For HV to identify the static VM configuration of post-launched VM.
2, Seed virtualization.
3, Slightly prevent launching malicous VM from SOS as lack of secure
boot.

The UUID is confused to user, user don't understand what it is. And user
don't know where to get/apply the UUID. The worst experience is user
can't launch any VMs w/o re-compile the hv. Everything needs to be
static decided in building phase.

Now we decide to remove UUID and split each usage. For 1st usage, use
vmname as the identifier of static VM configuration. For 2nd one, we
will use --vseed as the new parameter. For 3rd one, will pretect by
SOS's dm-verity.

This patch will remove the UUID parameter and support 1st&3rd usages
from DM part. For 2nd usage, another patch will be submitted later.
