f3627d4839 hv: Add update_vm_vlapic_state API to sync the VM vLAPIC state
This patch introduces vLAPIC state for a VM. The VM vLAPIC state can
be one of the following
 * VM_VLAPIC_X2APIC - All the vCPUs/vLAPICs (Except for those in Disabled mode) of this
	VM use x2APIC mode
 * VM_VLAPIC_XAPIC - All the vCPUs/vLAPICs (Except for those in Disabled mode) of this
	VM use xAPIC mode
 * VM_VLAPIC_DISABLED - All the vCPUs/vLAPICs of this VM are in Disabled mode
 * VM_VLAPIC_TRANSITION - Some of the vCPUs/vLAPICs of this VM (Except for those in Disabled mode)
	are in xAPIC and the others in x2APIC

Upon a vCPU updating the IA32_APIC_BASE MSR to switch LAPIC mode, this
API is called to sync the vLAPIC state of the VM. Upon VM creation and reset,
vLAPIC state is set to VM_VLAPIC_XAPIC, as ACRN starts the vCPUs vLAPIC in
XAPIC mode.

ac6c5dce81 HV: Clean vpic and vioapic logic when lapic is pt
When the lapic is passthru, vpic and vioapic cannot be used anymore. In
current code, user can still inject vpic interrupt to Guest OS, this is
not allowed.
This patch remove the vpic and vioapic initiate functions during
creating VM with lapic passthru. But the APIs in vpic and vioapic are
called in many places, for these APIs, follow the below principles:

1. For the APIs which will access uninitiated variables, and may case
hypervisor hang, add @pre to make sure user should call them after vpic or
vioapic is initiated.

2. For the APIs which only return some static value, do noting with them.

3. For the APIs which user will called to inject interrupt, such as
vioapic_set_irqline_lock or vpic_set_irqline, add condition in these
APIs to make sure it only inject interrupt when vpic or vioapic is
initiated. This change is to make sure the vuart or hypercall need not
to care whether lapic is passthru or the vpic and vioapic is initiated
or not.

ea7ca8595c HV: use tag to specify multiboot module
Previously multiboot mods[0] is designed for kernel module for all
pre-launched VMs including SOS VM, and mods[0].mm_string is used
to store kernel cmdline. This design could not satisfy the requirement
of hybrid mode scenarios that each VM might use their own kernel image
also ramdisk image. To resolve this problem, we will use a tag in
mods mm_string field to specify the module type. If the tag could
be matched with os_config of VM configurations, the corresponding
module would be loaded;

536c69b9ff hv: distinguish between LAPIC_PASSTHROUGH configured vs enabled
ACRN supports LAPIC emulation for guests using x86 APICv. When guest OS/BIOS
switches from xAPIC to x2APIC mode of operation, ACRN also supports switching
froom LAPIC emulation to LAPIC passthrough to guest. User/developer needs to
configure GUEST_FLAG_LAPIC_PASSTHROUGH for guest_flags in the corresponding
VM's config for ACRN to enable LAPIC passthrough.

This patch does the following

1)Fixes a bug in the abovementioned feature. For a guest that is
configured with GUEST_FLAG_LAPIC_PASSTHROUGH, during the time period guest is
using xAPIC mode of LAPIC,  virtual interrupts are not delivered. This can be
manifested as guest hang when it does not receive virtual timer interrupts.

2)ACRN exposes physical topology via CPUID leaf 0xb to LAPIC PT VMs. This patch
removes that condition and exposes virtual topology via CPUID leaf 0xb.

238d8bbaa2 reshuffle init_vm_boot_info
now only SOS need decide boot with de-privilege or direct boot mode, while
for other pre-launched VMs, they should use direct boot mode.

this patch merge boot/guest/direct_boot_info.c &
boot/guest/deprivilege_boot_info.c into boot/guest/vboot_info.c,
and change init_direct_vboot_info() function name to init_general_vm_boot_info().

in init_vm_boot_info(), depend on get_sos_boot_mode(), SOS may choose to init
vm boot info by setting the vm_sw_loader to deprivilege specific one; for SOS
using DIRECT_BOOT_MODE and all other VMS, they will use general_sw_loader as
vm_sw_loader and go through init_general_vm_boot_info() for virtual boot vm
info filling.

this patch also move spurious handler initilization for de-privilege mode from
boot/guest/deprivilege_boot.c to boot/guest/vboot_info.c, and just set it in
deprivilege sw_loader before irq enabling.

20f97f7559 restruct boot and bsp dir for firmware stuff
currently, ACRN hypervisor can either boot from sbl/abl or uefi, that's
why we have different firmware method under bsp & boot dirs.
but the fact is that we actually have two different operations based on
different guest boot mode:
1. de-privilege-boot: ACRN hypervisor will boot VM0 in the same context as
native(before entering hypervisor) - it means hypervisor will co-work with
ACRN UEFI bootloader, restore the context env and de-privilege this env
to VM0 guest.
2. direct-boot: ACRN hypervisor will directly boot different pre-launched
VM(including SOS), it will setup guest env by pre-defined configuration,
and prepare guest kernel image, ramdisk which fetch from multiboot modules.

this patch is trying to:
- rename files related with firmware, change them to guest vboot related
- restruct all guest boot stuff in boot & bsp dirs into a new boot/guest dir
- use de-privilege & direct boot to distinguish two different boot operations

this patch is pure file movement, the rename of functions based on old assumption will
be in the following patch.

5f87e716b8 hv: release IOMMU irte when releasing ptirq remapping entries
IRTE is freed if ptirq entry is released from remove_msix_remapping() or
remove_intx_remapping(). But if it's called from ptdev_release_all_entries(),
e.g. SOS shutdown/reboot, IRTE is not freed.

This patch adds a release_cb() callback function to do any architectural
specific cleanup. In x86, it's used to release IRTE.

On VM shutdown, vpci_cleanup() needs to remove MSI/MSI-X remapping on
ptirq entries, thus it should be called before ptdev_release_all_entries().

For pre-launched VMs MSI/MSI-x configuration writes are not intercepted by ACRN.
It is pass-thru and interrupts land in ACRN and the guest vector is injected into
the VM's vLAPIC. With this patch, ACRN intercepts MSI/MSI-x config writes and take
the code path to remap interrupt vector/APIC ID as it does for SOS/UOS.

ede1459e19 hv: fix the vm pointer check before use
After using get_vm_from_vmid(), vm pointer is always not NULL. But there are still many NULL pointer checks.
This commit replaced the NULL vm pointer check with a validation check which checks the vm status.
In addition, NULL check for pointer returned by get_sos_vm() and get_vm_config() is removed.

cee45a80d9 hv: add default handlers for PIO/MMIO access
Add the default handlers for PIO and MMIO access which returns all
FFs on read and discards write. These default handlers are registered
when SOS VM or pre-launched VM is created.

v3 -> v4:
- use single layer if in hv_emulate_pio
- change the implementation of pio_default_read

v2 -> v3:
- use runtime vm type instead of CONFIG_PARTITION_MODE
- revise the pio/mmio emulation functions
- revise the pio/mmio default read functions according to MISRA C
- revise the commit message

v1 -> v2:
- add default handlers members in struct acrn_vm and add interfaces
  to register default handlers for PIO and MMIO.

382acfaf28 HV: Using INIT to kick vCPUs off when RTVM poweroff by itself
When RTVM is trying to poweroff by itself, we use INIT to
kick vCPUs off the non-root mode.

For RTVM, only if vm state equal VM_POWERING_OFF, we take action to pause
the vCPUs with INIT signal. Otherwise, we will reject the pause request.

83d11bbff8 HV: Register S5 pio handler for dm-launched RTVM
The virtual pm port of RTVM is intercepted by HV. But the HV needs to inform the DM as well.
So we will forward the virtual S5 request to DM too

The handler in HV just set the pm state flag (VM_POWERING_OFF) which indicate that the RTVM is powering
off by itself. Meanwhile, there are data resources in VHM and DM should be released once we handle the PM
of RTVM in HV. So, return to DM to go through the entire VM destroy cycles to release the resources.
During the cycles, the DM will try to pause vm through hypercall. In the hypercall handler in HV, we will
check the pm state flag. If it is set, pause all the vCPUs of the vm. Otherwise, reject the request.

In this way, we can make sure that RTVM can only trigger its s5 by itself. All
other S5 request from external will be rejected.

Here is sequence chart of RTVM s5.

5398c901f6 hv: remove CONFIG_PARTITION_MODE for pre-launched VM vE820 creation
Preparing for hybrid mode:

- create vE820 for pre-launched VMs and do other init code when the
  vm_config->type is PRE_LAUNCHED_VM.
- create ve820.c for each board because without wrapping by
  CONFIG_PARTITION_MODE, ve820_entry[] needs to be visible even when
  compiling target boards that haven't enabled pre-launched VMs.
- remove create_prelaunched_vm_e820() from vm.c and implement board
  specific function for each $(CONFIG_BOARD)/ve820.c. The reasons being:
  - don't need to define ve820_entry[32] for those boards that don't
    support pre-launched VMs.
  - more importantly, this makes it much easier to create different per-VM
    vE820 when it's needed.

The 'actual' hypervisor page table installed in enable_paging() is 1:1

hpa2hva() are implemented based on these page tables and can't be used
when the init page tables take effect.

This patch does the following cleanup:

- remove all hva2hpa()/hpa2hva() before calling enable_paging()
- get_hv_image_base() returns HVA, not HPA. So add hva2hpa() for all cases
  that are called afte enable_paging().

66e0023029 HV: sanitize vm config
Add a API to sanitize vm_configs[] array, in this API, we will do sanity
check for VM configurations and refill some fields in vm_configs[]. If
sanity check is failed, the HV would reject to boot.

About pcpu_bitmap of SOS_VM:

We should not hard code pcpu_bitmap for SOS_VM, this is not convenient for
unconfigured boards. The pcpu_bitmap follows a very simple rule:

All physical CPUs except ocuppied by Pre-launched VMs are all belong to
SOS_VM. In this way, the pcpu_bitmap of a SOS_VM is decided by pcpu_bitmap
status in PRE_LAUNCHED_VMs.

To get the correct pcpu_bitmap of SOS_VM, We need to setup another rule, that
the vm_configs[] array should follow the order of PRE_LAUNCHED_VM - SOS_VM
strictly.

With this patch enabled, the pcpu_bitmap field of sos vm config is not needed
to configure;

	         When I/O request is completed, SOS will mark the completion status and

e8296dce05 hv: Add IO request completion polling feature
This patch introduce a new mode of IO request completion, polling mode.

Now, the sketch of ioreq process can be,
  A. UOS vcpu0 generate PIO/MMIO ->
   B. pcpu1(vcpu0 of UOS) trap into HV ->
    C. pcpu1 build ioreq, send IPI and enter idle ->
     D.1 pcpu0(vcpu0 of SOS) response IPI,
     D.2 pcpu0 handle the ioreq in HV, kernel, DM,
     D.3 pcpu0 mark ioreq as complete,
     D.4 pcpu0 hypercall to enter HV ->
       E.1 pcpu0 send IPI to wake pcpu1 up
       E.2 UOS vcpu0 continue running

With this change, it skips D.4, E.1 steps. In step C, pcpu1 will enter a
polling ioreq state idle after send out the IPI.
It can save about ~5000 cpu cycles.

In polling mode, we do the polling in idle instead of pause cpu all the
time. It will consume more power. A better way is to use monitor/mwait
instructions which can put cpu into a sleep state with monitoring a
memory address. Unfortunately, APL has bug with monitor. We can gather
all ioreqs state into one monitorable memory and take advantage of
monitor/mwait for future platform.

The way polling or notification is per VM. We can config VMs in
different mode. By default, IO request completion will use notification
mode for all VMs. We can switch it by Kconfig.

  In some cases such as UOS S3 or UOS system reset,

  Because PD/PT are shared in both secure world's EPT
  and normal world's EPT,before freeing trusty EPT,
  it will memset all PDPTEs except trusty memory,
  then call 'free_ept_mem', it can only free trusty EPT,
  and does't affect shared normal world EPT.

4dc39fdb8e HV:treewide:Add 16-bit atomic operations and update vpid type
There are some integer type conversions reported by static
analysis tool for vcpu id, number of created vcpus, and
vpid, to reduce these type conversions, redesign vcpu id,
number of created vcpus, and vpid type as uint16_t as per
their usage, related 16-bit atomic operations shall be
added in HV.
MISRA C requires that all unsigned constants should have the suffix 'U'
(e.g. 0xffU), but the assembler may not accept such C-style constants.

Add 16-bit atomic add/dec/store operations;
Update temporary variables type and parameters type of
related caller;
Update vpid type as uint16_t;
Replace Macro with constant value for CPU_PAGE_SIZE.

Note: According to SDM A.10, there are some bits defined
in the IA32_VMX_EPT_VPID_CAP MSR to support the INVVPID
instruction, these bits don't mean actual VPID, so
the vpid field in the data struct vmx_capability doesn't
be updated.

V1--V2:
	update comments for assembly code as per coding style;

ACRN needs to trap the pm1a/pm1b written/read from VM0. So we
could know when should we put the system to S3.

We will have two path back to VM0:
 - S3 enter/exit sucess. Will reset VM0 and jump to VM0 wakeup vec
   with real mode
 - S3 enter/exit failed. Will return to the next instruction of
   pm1a/pm1b register writing. VM0 will read the pm1a/pm1b evt
   register to check whether it's waked up or not.
