Zhao Yakui 072e77e746 DM: Disable plane_restriction on 4.19 kernel
Now the plane_restriction is not ready on 4.19-rcX kernel. So it will be
disabled temporally.
This change is only used to disable the plane_restriction for UOS when UOS
based on 4.14 kernel is launched in 4.19 sos kernel.

V1->V2: Commit log adds the description that this change is used to disable
the plane_restriction in 4.14 UOS kernel.

Zhao Yakui 5a64af2066 DM: Use the pass-through mode for IPU on 4.19 kernel
Now the IPU mediator driver is not ready on 4.19-rcX kernel. So the IPU will
fallback to pass-trhough mode temporally and be assigned to guest directly.
After the IPU mediator driver is ready, the ipu_passthrough flag will be
changed to zero.

V1-V2: Describe the issue clearly in commit log.

Zhao Yakui 38099e4b78 DM: Add the boot option to avoid loading dwc3_pci USB driver
The latest kernel has some issues when unloading dwc3_pci USB driver.
It will cause the kernel panic when unloading dwc3_pci driver in order to
assign USB controller to guest.
So the dwc3_pci won't be loaded.

Xiaoguang Wu 0d4a88e620 DM USB: xHCI: change logic of binding libusb to native device
Previous implementation binds libusb (in other words: usbfs) with
native device when DM receives the Enable Slot command. But according
to xHCI spec 4.6.5, the binding relationship is decided when the
Address Device command is received, so this implementation is not
consistent with hardware behaviors.

And this incompatible could induce following issue. When two or more
USB devices are connected at the same time, eg, connecting two devices
before Guest OS is booted, the virtual slot id may bind to wrong root
hub port.

This patch will do the binding when Address Device command is received
and related issues will be fixed.

Yin Fengwei 9df8790ffc hv: Fix two minor issues in instruction emulation code
1. The wrong operand size is assigned in instruction decode phase
   if the operand size is 1 byte.

   According to the SDM, the bit 0(w bit) of opcode should be checked
   first to detect whether the operand size is 1 byte. Then, check
   whether there is prefix to overwrite the default operand size.

   The original instruction decode doesn't care about the operand
   size. But do opsize fixup during instruction emulation phase.
   With ACRN we need operand size packed to ioreq and send to DM
   after instruction decode.

2. We should always touch the GPA by following opsize to avoid side
   effect (especially when GPA is for a MMIO).

Shuo Liu 56992c7373 dm: combine VM creating and ioreq shared page setup
This patch depends on a vhm patch merged, "vhm: setup ioreq shared buf
in IC_CREATE_VM ioctl". We intend to combine VM creating and ioreq
shared page setup into one step. For compatibility issue, we need follow
the patch dependency to merge accordingly.

This patch also drops vm_open/vm_close which will be intergrated into
vm_create/vm_destroy.

Zhao Yakui a189be26ff HV: Add one hcall to set the upcall vector passed from sos_kernel
Currently the acrn-hypervisor is using the PLATFORM_IPI vector to notify
the sos_kernel. And then sos_kernel will handle the notification from acrn
hypervisor in PLATFORM_IPI ISR. But as the PLATFORM_IPI ISR can be registered
by the other modules, it will have the conflict when trying to register
acrn intr ISR. So the HYPERVISOR_CALLBACK_VECTOR will be used instead.

In order to switch the notification vector from PLATFORM_IPI to
HYPERVISOR_CALLBACK_VECTOR, one API is added so that sos can configure
the up-notifier interrrupt vector.

Zhao Yakui 228699131b HV: Add the definition of VECTOR_HYPERVISOR_CALLBACK_VHM
It is from the HYPERVISOR_CALLBACK_VECTOR in sos_kernel.
After this vector is used in both kernel and hypervisor, this will be defined
as the default vector.

Zhao Yakui a8e688eb72 HV: Use the variable to fire VHM interrupt
This is to do the preparation of switch the notifier vector from
PLATFORM_IPI to HYPERVISOR_CALLBACK_VECTOR.
