Zide Chen 873ed752d4 misc: sanity check VM config for nested virtualization
- SOS does not allow LAPIC passthru unless nested virtualization is
  enabled on SOS.

- Currently nested virtualization requires LAPIC passthru, so if
  GUEST_FLAG_VMX_ENABLED is set, GUEST_FLAG_LAPIC_PASSTHROUGH must be
  set in same VM.

- Per VM GUEST_FLAG_VMX_ENABLED can be set only if CONFIG_VMX_ENABLED
  is set.

Liang Yi 688a41c290 hv: mod: do not use explicit arch name when including headers
Instead of "#include <x86/foo.h>", use "#include <asm/foo.h>".

In other words, we are adopting the same practice in Linux kernel.

Geoffroy Van Cutsem 79892f911d misc: adjust code for gcc-10
The latest gcc 10.x changes the default to '-fno-common'. This causes a couple
of build failures in ACRN. This patch changes the default behaviour to
'-fcommon' for the 'acrnprobe' tool and fixes the 'hv_prebuild' codebase.

More details on that change can be found here:

Tao Yuhong 55b7fae67a HV: pci-vuart: pci based vuart emulation
Add emulation for pci based vuart device mcs9900 at hv land.
add struct pci_vdev_ops vuart_pci_ops, the vdev callbalks for vuart.

How to use
In misc/vm_configs/scenarios/<SCENARIO>/<BOARD>/pci_dev.c, add pci
vuart config to vm_pci_devs[] array. For example:

struct acrn_vm_pci_dev_config vm0_pci_devs[] = {
       /* console vuart setting*/
       {
               .emu_type = PCI_DEV_TYPE_HVEMUL,
               .vbdf.bits = {.b = 0x00U, .d = 0x04U, .f = 0x00U},
               .vdev_ops = &vmcs_ops,
               .vbar_base[0] = 0x80001000,	/* mmio bar */
               .vbar_base[1] = 0x80002000,	/* msix bar */
               .vuart_idx = 0,
       },
       /* communication vuart setting */
       {
               .emu_type = PCI_DEV_TYPE_HVEMUL,
               .vbdf.bits = {.b = 0x00U, .d = 0x05U, .f = 0x00U},
               .vdev_ops = &vmcs_ops,
               .vbar_base[0] = 0x80003000,
               .vbar_base[1] = 0x80004000,
               .vuart_idx = 1,
               .t_vuart.vm_id = 1U,
               .t_vuart.vuart_id = 1U,
       },
}

dongshen a425730f64 acrn-config: rename MAX_PLATFORM_CLOS_NUM to HV_SUPPORTED_MAX_CLOS
HV_SUPPORTED_MAX_CLOS:
 This value represents the maximum CLOS that is allowed by ACRN hypervisor.
 This value is set to be least common Max CLOS (CPUID.(EAX=0x10,ECX=ResID):EDX[15:0])
 among all supported RDT resources in the platform. In other words, it is
 min(maximum CLOS of L2, L3 and MBA). This is done in order to have consistent
 CLOS allocations between all the RDT resources.

add an IVSHMEM regoin and the related configuration parameters in
hybrid_rt scenario on whl-ipc-i5. The size of the shared memory is
2M, and it is used for the communication between VM0 and VM2.

v6: rename shm name; remove unnecessary MACROs.

v7: rename MACRO for shm name; add unassigned vbdf for post-launched
    VMs.

Victor Sun b5dfe369da HV: move vm configuration check to pre-build time
This patch will move the VM configuration check to pre-build stage,
a test program will do the check for pre-defined VM configuration
data before making hypervisor binary. If test failed, the make
process will be aborted. So once the hypervisor binary is built
successfully or start to run, it means the VM configuration has
been sanitized.

The patch did not add any new VM configuration check function,
it just port the original sanitize_vm_config() function from cpu.c
to static_checks.c with below change:
  1. remove runtime rdt detection for clos check;
  2. replace pr_err() from logmsg.h with printf() from stdio.h;
  3. replace runtime call get_pcpu_nums() in ALL_CPUS_MASK macro
     with static defined MAX_PCPU_NUM;
  4. remove cpu_affinity check since pre-launched VM might share
     pcpu with SOS VM;

The BOARD/SCENARIO parameter check and configuration folder check is
also moved to prebuild Makefile.
