Zhao Yakui 8b7767e643 ACRN:DM:VGPU: Fix the incorrect use after free

Zhao Yakui 2a7a269313 ACRN:DM:VDISPLAY:Fix the possible access after free
When virtio-gpu tries to submit the framebuffer based on
VIRTIO_GPU_CMD_2D, one pixman_image will be created. When the
sdl rendering_thread is terminated, the pixman_image will be 
released. But its pointer is set to NULL. In the next reboot,
its access in vdpy_surface_set is incorrect.

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!

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.

many legacy and modern OS. Many installer of OS distribution use
this interface to display the GUI of installer when setup a refresh
new installation on bare-metal. Besides, Windows OS always use this
interface to display it's BSOD, recovery mode & safe mode GUI. It
is need because Windows don't include virtio-gpu driver as their
in-box driver, VGA interface will be used before the virtio-gpu
driver been installed.
To be compatiable with the PCI bar layout of legacy VGA, the layout
is refined to meet with the requirement of legacy VGA and modern

Zhao Yakui eb9a58c70e ACRN:DM: Set the desired state to inject PCI legacy intx
When the virtio-XXX pci devices fall back to legacy PCI intx,
the pci_irq_assert is called to inject the interrupt and then
the pci_irq_deassert is used to mark the completion of PCI interrupt.
Currently the HV vIOAPIC uses the pin_state for the interrupt injection
of legacy PCI intx. In such case it will fail to inject the PCI legacy
intx and the guest system fails to be booted when adding the boot option
of "pci=nomsi".

PCI legacy INTx usually use active low level trigger mode as it is Open-Drain
state and allows multitple interrupt signals to share a single line.
https://wiki.osdev.org/PCI_Local_Bus_Signals
In such case DM needs to set the correct state for the PCI device so that the
HV vIOAPIC can help to inject the PCI legacy intx.

BTW: When the MSI/MSIX is used for PCI device, it uses another mechanism
to inject the interrupt. It is harmless to configure the initial state.

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.

Xiangyang Wu a31bd7bb0d DM: add command module for command monitor
The command module provides interfaces to find a command
intance, register handler for specified command, dispatch
command and invoke related handler.
find_command: find a command instance by name.
register_command_handler: register the handler for one
command instance.
dispatch_command_handlers: dispatch the command and invoke
registered handler.

v1-->v2:
	Only support single handler for one command instance.
v2-->v3:
	Remove command id.
	Add error check to avoid regiter handler to command
	instance which has handler.
	Update the second parameter type of register_command_handler
	to avoid unnecessary type conversion.

Xiangyang Wu 26fdfc6a30 DM: add socket module for command monitor
The socket module is to provide interfaces below, the unix domain
socket can be created by command monitor for the communication
between DM instance and libvirt daemon or kata container:
init_socket: allocate a new socket instance according to socket path
deinit_socket: free a socket instance
open_socket: open one unix domain socket server, initialize a
socket, create one thread to listen to client, another thread to
poll message from client.
close_socket: close one unix domain socket server
find_socket_client: find socket client instance according to fd
write_socket_char: send message through unix domain socket server

v1--v2:
	Update some log message format and copyright format.
v2-->v3:
	Update SOCKET_MAX_CLIENT to 1H since the socket instance of
	command monitor only have one client (libvirt or kata container).

Yuanyuan Zhao 47ff99fd64 dm: rtvm enable lapic_pt automatically
Enable `lapic_pt` automatically for rtvm for better performance.

Reserve `--lapic_pt` for future use. If VM is not in realtime mode,
`--lapic_pt` will cause a warning.

Yonghua Huang 4b0590415d dm: disable TCC strict CPU affinity check
By default, pCPU is allowed to request software SRAM buffer
 from given region in TCC buffer driver only if this pCPU is
 set in the target region's CPU affinity configuration.

 This check shall be disabled for software SRAM virtualization
 usage in ACRN service VM, because software SRAM buffers are
 requested by ACRN DM on behalf of user VM, but ACRN DM and
 user VM may run on different CPUs while the target software
 SRAM region may be configured only for pCPUs that user VM runs on.

 This patch turns off such affinity check in TCC driver when
 initializing vSSRAM for user VM.

Chenli Wei df9bab9aca dm: refine the mac check logic for virtio-net
The current mac detection logic only check whether there are parameters
after tap opt. Don't care whether the parameter is MAC or not, then
mac_provided will be set to 1, which will disable the mac_seed setting
when using sub parameters

This patch will check opt and fix the above issue.

GET_PLATFORM_INFO IOCTL syscall will not be supported

 on it hence shall be removed.

 Without vm_get_config(), vm_get_cpu_affinity_dm() is used

Yuanyuan Zhao 8a44067f8b dm: use lapic id to set cpu affinity.
Cpu affinty was set by pcpu id which can't be obtained
explictly by user. Use lapic id instead which can be easily
read from `/proc/cpuinfo` as `apicid`.

Yuanyuan Zhao c5537ec4d4 dm: get lapic id from madt
The GET_PLATFORM_INFO will be removed from hypervisor. The acrn-dm can
only refer to Service VM's resources from now, all the resources out of
Service VM are not awared by acrn-dm. The original info got from
GET_PLATFORM_INFO needs to changed to Service VM's perspective like lapic id.

The pcpu_id is the index of lapic instance in MADT table. This patch
parses the Service VM's MADT table to convert the pcpu_id to lapic_id instead
of GET_PLATFORM_INFO.
