ACRN disables Snoop Control in VT-d DMAR engines for simplifing the
implementation. Also, since the snoop behavior of PCIE transactions
can be controlled by guest drivers, some devices may take the advantage
of the NO_SNOOP_ATTRIBUTE of PCIE transactions for better performance
when snoop is not needed. No matter ACRN enables or disables Snoop
Control, the DMA operations of passthrough devices behave correctly
from guests' point of view.

This patch is used to clean all the snoop related code.

access memory when the SNOOP bit of Secondary Level page PTE (SL-PTE)
is set, this will cause many undefined issues such as invisible cursor
in WaaG etc.

Current hv design uses EPT as Scondary Leval Page for iommu, and this
patch removes the codes of setting SNOOP bit in both EPT-PTE and SL-PTE
to avoid errors.

And according to SDM 28.2.2, the SNOOP bit (11th bit) will be ignored
by EPT, so it will not affect the CPU address translation.

Zide Chen 6040d8f6a2 hv: fix SOS vapic_id assignment issue
Currently vlapic_build_id() uses vcpu_id to retrieve the lapic_id
per_cpu variable:

  vlapic_id = per_cpu(lapic_id, vcpu->vcpu_id);

SOS vcpu_id may not equal to pcpu_id, and in that case it runs into
problems. For example, if any pre-launched VMs are launched on PCPUs
whose IDs are smaller than any PCPU IDs that are used by SOS.

This patch fixes the issue and simplify the code to create or get
vapic_id by:

- assign vapic_id in create_vlapic(), which now takes pcpu_id as input
  argument, and save it in the new field: vlapic->vapic_id, which will
  never be changed.
- simplify vlapic_get_apicid() by returning te saved vapid_id directly.
- remove vlapic_build_id().
- vlapic_init() is only called once, merge it into vlapic_create().

dongshen 00ad3863a1 hv: maintain a per-pCPU array of vCPUs and handle posted interrupt IRQs
Maintain a per-pCPU array of vCPUs (struct acrn_vcpu *vcpu_array[CONFIG_MAX_VM_NUM]),
one VM cannot have multiple vCPUs share one pcpu, so we can utilize this property
and use the containing VM's vm_id as the index to the vCPU array:

 In create_vcpu(), we simply do:
   per_cpu(vcpu_array, pcpu_id)[vm->vm_id] = vcpu;

 In offline_vcpu():
   per_cpu(vcpu_array, pcpuid_from_vcpu(vcpu))[vcpu->vm->vm_id] = NULL;

so basically we use the containing VM's vm_id as the index to the vCPU array,
as well as the index of posted interrupt IRQ/vector pair that are assigned
to this vCPU:
  0: first vCPU and first posted interrupt IRQs/vector pair
  (POSTED_INTR_IRQ/POSTED_INTR_VECTOR)
  ...
  CONFIG_MAX_VM_NUM-1: last vCPU and last posted interrupt IRQs/vector pair
  ((POSTED_INTR_IRQ + CONFIG_MAX_VM_NUM - 1U)/(POSTED_INTR_VECTOR + CONFIG_MAX_VM_NUM - 1U)

In the posted interrupt handler, it will do the following:
 Translate the IRQ into a zero based index of where the vCPU
 is located in the vCPU list for current pCPU. Once the
 vCPU is found, we wake up the waiting thread and record
 this request as ACRN_REQUEST_EVENT

dongshen 14fa9c563c hv: define posted interrupt IRQs/vectors
This is a preparation patch for adding support for VT-d PI
related vCPU scheduling.

ACRN does not support vCPU migration, one vCPU always runs on
the same pCPU, so PI's ndst is never changed after startup.

VCPUs of a VM won’t share same pCPU. So the maximum possible number
of VCPUs that can run on a pCPU is CONFIG_MAX_VM_NUM.

Allocate unique Activation Notification Vectors (ANV) for each vCPU
that belongs to the same pCPU, the ANVs need only be unique within each
pCPU, not across all vCPUs. This reduces # of pre-allocated ANVs for
posted interrupts to CONFIG_MAX_VM_NUM, and enables ACRN to avoid
switching between active and wake-up vector values in the posted
interrupt descriptor on vCPU scheduling state changes.

A total of CONFIG_MAX_VM_NUM consecutive IRQs/vectors are reserved
for posted interrupts use.

The code first initializes vcpu->arch.pid.control.bits.nv dynamically
(will be added in subsequent patch), the other code shall use
vcpu->arch.pid.control.bits.nv instead of the hard-coded notification vectors.

Rename some functions:
  apicv_post_intr --> apicv_trigger_pi_anv
  posted_intr_notification --> handle_pi_notification
  setup_posted_intr_notification --> setup_pi_notification

dongshen c2d350c5cc hv: enable VT-d PI for ptdev if intr_src->pid_addr is non-zero
Fill in posted interrupt fields (vector, pda, etc) and set mode to 1 to
enable VT-d PI (posted mode) for this ptdev.

If intr_src->pi_vcpu is 0, fall back to use the remapped mode.

dongshen f7be985a23 hv: check if the IRQ is intended for a single destination vCPU
Given the vcpumask, check if the IRQ is single destination
and return the destination vCPU if so, the address of associated PI
descriptor for this vCPU can then be passed to dmar_assign_irte() to
set up the posted interrupt IRTE for this device.

For fixed mode interrupt delivery, all vCPUs listed in vcpumask should
service the interrupt requested. But VT-d PI cannot support multicast/broadcast
IRQs, it only supports single CPU destination. So the number of vCPUs
shall be 1 in order to handle IRQ in posted mode for this device.

Add pid_paddr to struct intr_source. If platform_caps.pi is true and
the IRQ is single-destination, pass the physical address of the destination
vCPU's PID to ptirq_build_physical_msi and dmar_assign_irte

dongshen 6496da7c56 hv: add function to check if using posted interrupt is possible for vm
Add platform_caps.c to maintain platform related information

Set platform_caps.pi to true if all iommus are posted interrupt capable, false
otherwise

If lapic passthru is not configured and platform_caps.pi is true, the vm
may be able to use posted interrupt for a ptdev, if the ptdev's IRQ is
single-destination

Sainath Grandhi 47f883db30 hv: Hypervisor access to PCI devices with 64-bit MMIO BARs
PCI devices with 64-bit MMIO BARs and requiring large MMIO space
can be assigned with physical address range at the very high end of
platform supported physical address space.

This patch uses the board info for 64-bit MMIO window as programmed
by BIOS and constructs 1G page tables for the same.

As ACRN uses identity mapping from Linear to Physical address space
physical addresses upto 48 bit or 256TB can be supported.
