1ed96bfbf8 dm: virtio-gpu: VGA compability support
Legacy VGA & VBE interface as a common interface is supported by
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
virtio-gpu.

It can display graphic outputs of guest vm which is stored in
service vm's buffers by virtio-gpu. Display operation is accelerated
by Intel GPU PF(SRIOV) device with SDL(OpenGL ES 2.0 backend) API.
This provides one generic display solution. When the virtio-gpu is

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.

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:
   in mevent_qlock () at core/mevent.c:93
   in mevent_delete_even at core/mevent.c:357
    ===>Recursively LOCK
   in mevent_delete_close at core/mevent.c:387
   in acrn_timer_deinit at core/timer.c:106
   in virtio_reset_dev at hw/pci/virtio/virtio.c:171
   in virtio_console_reset at
     hw/pci/virtio/virtio_console.c:196
   in virtio_console_destroy at
    hw/pci/virtio/virtio_console.c:1015
   in virtio_console_teardown_backend at
    hw/pci/virtio/virtio_console.c:1042
   in mevent_drain_del_list () at
    core/mevent.c:348 ===> 1st LOCK
   in mevent_dispatch () at core/mevent.c:472
   in main at core/main.c:1110

  So the root cause is:
  mevent_mutex lock is recursively locked by mevent thread
  itself ( for this first lock and  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.

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().

7d0c05f3ff dm: Skip injecting _PPC and _PCT when _PSS is not constructed
This patch is to eliminate kernel error msgs:
'ACPI Error: AE_NOT_FOUND, Evaluating _PSS'

This is caused by missing of _PSS table in guest ACPI. It would
happen when pstate is not injected to the guest.

Kernel ACPI pstate driver first probes
_PPC(performance capabilites) and _PCT(performance control)
in ACPI. If they exist, then it loads the _PSS(performance state).
If _PPC/_PCT are presented while _PSS is missing, it prints
the error msg.

In acrn-dm, _PPC/_PCT are hard-coded to all vCPUs, while _PSS
are constructed with the pCPUs' pstate data. This is base on
assumption that all VMs can have pstate.

Now the pstate is given to VM only when the VM is not sharing
any CPU(and no RTVM is setup in the scenario).
When the VM doesn't have pstate, the hypercall will return px_cnt=0,
and the _PSS is not constructed. In this case, _PPC/PCT should not
be injected, too.

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.

hv is responsible to ensure PTM is always enabled on hw root port if
that root port is PTM root-capable.  If PTM root is not enabled already in physical
root port before guest launch, guest OS can only enable it in root port's virtual
config space and PTM may not function as desired so we would rather not
to allow user to enable PTM on pass-thru device in this case.
Also revisit a few comments to add assumption that acrn only support a
simple PTM hierarch emulation i.e., EP (ptm requestor) is directly connected
to root port (ptm root), or ptm requestor is rcie).

V4:
 - Change behavior from V3: When users tries to enable PTM while PTM root is not enabled on
physical root port, allow user to launch VM and pass thru the device
with no PTM support.
V3:
 - When users tries to enable PTM while PTM root is not enabled on
physical root port, allow user to launch VM and enable PTM in virtual
root port.  This is not going to enable PTM on physical root port.

"--pm_notify_channel uart" means a vuart channel will be created in the
User VM to allow communication with the VM's life_mngr. The Service VM
can then initiate S5 in the guest via its dm's monitor interface. The
additional option, "allow_trigger_s5", will create a socket connection

    Change 64-bit MMIO BAR window to 256G-512G

    DM maps 64-bit mmio BARs of vdev into 4G-5G, for post-launched VMs. At native
    platform, 64-bit MMIO BARs which have 39-bit address, are always mapped into
    256G-512G address space.
    DM will change the address window of 64-bit vdev BARs of post-launched VMs to
    256G-512G. That ask OVMF to do the same change, to boot from passthrough SATA/MVME
    disks, which have 64-bit MMIO BAR.

ACRN didn't support dynamic memory allocation. SO it would reserve
a big page pool and use the GPA as index to get a page to do EPT
mapping. In order to save memory, we put high MMIO windows to [4G, 5G].
AFter we support dynamic page allocation for EPT mapping, we move
high MMIO windows to where it used to ([256G, 512G]) for 39 bits physical
address), we could move high memory to where is used to too ([4G, 4G +
size]).

If acrn-dm create pci vuart with
'-s,<slot>,uart,vuart_idx:<value>', then acrn-dm will not
create pci uart at DM land, but create an vuart-pci virtual device
at HV land.
When create a HV land vuart-pci vdev, user must specify its vuart id.
Which is defined in vm_config, is the acrn_vm_pci_dev_config.vuart_idx

460124f984 dm: e820: refine e820 layout
We don't reserve PCI MMIO in e820 Table, it's included in DSDT ACPI Table.
About 0xA0000 - 0x100000 entry, we don't have any ACPI Table touch this region.
So we could remove it too.

After this change, we could only pass the reserved e820 table which we must
reserve to OVMF. In this case, the OVMF could trust ACRN-DM and pass the
reserved e820 table to guest instead of dropping it.

This patch needs the corresponding modify in OVMF. Otherwise, the guest could
not boot.

830b7749de dm: correctly handle EAGAIN in pm_vuart when listening
pm_vuart stops listening and relays the message right away if it
encounters EAGAIN during read(). This causes the messages relayed to be
fragmented.

Only relay the message when it encounters a null character or a newline
character, or when the buffer is full.
