Vijay Dhanraj 517707dee4 DM/HV: Increase VM name len
VM Name length is restricted to 32 characters. kata creates
a VM name with GUID added as a part of VM name making it around
80 characters. So increasing this size to 128.

v1->v2:
It turns out that MAX_VM_OS_NAME_LEN usage in DM and HV are for
different use cases. So removing the macro from acrn_common.h.
Definied macro MAX_VMNAME_LEN for DM purposes in dm.h. Retaining
original macron name MAX_VM_OS_NAME_LEN for HV purposes but defined
in vm_config.h.

Peter Fang f412d52546 dm: protect pthread_cond_wait() against spurious wakeups
Users of pthread_cond_wait() should take care of spurious wakeups and it
is usually used in conjunction with a predicate. Not doing so can result
in unintended behavior. For example:

virtio_net_tx_thread():
  entry -> pthread_cond_wait() -> spurious wakeup ->
  vq_clear_used_ring_flags() -> segfault (vq->used uninitialized)

tpm_crb_request_deliver():
  entry -> pthread_cond_wait() -> spurious wakeup ->
  swtpm_handle_request() called needlessly

virtio_rnd_get_entropy():
  entry -> pthread_cond_wait() -> spurious wakeup ->
  no avail ring processing ->
  virtio_rnd_notify() skips pthread_cond_signal() due to
  rnd->in_progress ->
  vq_endchains() called needlessly ->
  wait in pthread_cond_wait() indefinitely

Fix these uses of pthread_cond_wait() by using predicates.

The only use case without a clear predicate is the tx thread in
virtio-mei, because it works with two-dimensional linked lists.

v1 -> v2:
- fix bugs and comments
- reduce code redundancy

Peter Fang 20164799cb dm: leave a gap for 32-bit PCI hole in E820 map
Guest OS (e.g. Linux) may rely on a gap in E820 map in the 32-bit memory
space to determine the MMIO space for its PCI devices. Leave this gap
when building E820 map to keep the guest's PCI subsystem working.

After commit 7752d5cfe3d11ca0bb9c673ec38bd78ba6578f8e, Linux kernel no
longer requires the MMCONFIG region to be reserved in the E820 map.
Nonetheless, keep it in the reserved region to be on the safe side.

Xiaoguang Wu b159d66fb3 DM USB: refine the polling thread for libusb events
The thread function usb_dev_sys_thread is the source of libusb events,
which is also the basis of USB/xHCI emulation. During S3 process,
function libusb_handle_events_timeout may fail and return -1, which
could result of exit of the thread (BTW, this failure is resulted from
USB native reseting behavior during S3). Under this situation, the emulation
of USB/xHCI could never continue.

This patch fix this issue by continuing to call libusb_handle_events_timeout
even it reture -1. The return value will be finally ok after S3 process is
completed.

This patch will continue poll after failure and hence fix this issue.
