vPIT is used as a source of system timer by UEFI (e.g. OVMF).
This is ported from Bhyve, with a few changes:
- move to user space, using POSIX timer
- support timer mode 3
- improve the emulation of OUT and STATUS byte
- improve the emulation of counter behavior
- improve the emulation of CE update in periodic mode
- treat CR == 0 as 0x10000

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.

Netmap/vale attempts to speed up network communication by bypassing the
TCP/IP network stack, which requires patching the physical NIC driver so
that applications developed based on netmap can interact directly with
the physical NIC driver. It may make sense for some specific scenarios
which requres very high bandwith (10Gb/s or 100Gb/s), we can even put up
with the complexity and compatibility introduced by this techology.
However for ACRN, a virtualization solution for IoT, there is no need to
support this backend. For 1Gb NICs or below, the VBS-U/tap solution
can already achieve near-native bandwidth. To keep simplicity and
improve compatibility, remove the netmap/vale support in dm.

In the current implementation sigev_notify is configured as
SIGEV_THREAD. When timer expires an async thread is created and
the registered timer callback is called in the context of this
thread. vrtc_update_timer will access the global data vrtc. There
is a race condition that vrtc is freed when deinit and then a timer
expires. In this case vrtc_update_timer will access a freed buffer
which causes problem such as heap corruption and segment fault.
In this patch signal model is used when timer is created. The signal
is masked and a signalfd is used to poll on it with mevent. This avoids
the race condition.

The xHCI emulation greatly depends on the user space library libusb
which is based on the usbfs module in Linux kernel. The libusb will
bind usbfs to physical USB device which makes hardware control over
libusb in user space possible.
The pci_xhci_dev_create is called in pci_xhci_native_usb_dev_conn_cb
which is a callback function triggered by physical USB device plugging.
This function will bind the physical USB device to usbfs in SOS, which
we depend to create the communication between UOS xHCI driver with
physical USB device.
This design will fail if the reconnection happened in the SOS, which
will bind class driver to the physical USB device instead of usbfs,
hence the libusb device handle in DM is invalid.
Currently, the native S3 will disable the vbus for all xHCI ports and
re-drive during S3 resume. This behavior cause native USB driver unbind
the usbfs and bind to related class driver, then made the DM lost
control and failed to continue emulation.
To fix this issue, place the pci_xhci_dev_create in the function
pci_xhci_cmd_enable_slot. According to the xHCI spec 4.5.3 Figure 10,
the UOS always send Enable Slot command when a device is attached or
recovered from errors (by Disable Slot command). So every time the SOS
can't resuming normally or some unexpected disconnection happens, this
desigen will always survive by Disable Slot and Enable Slot command
series from UOS xHCI driver.

In UOS, during the process of xHCI resuming, the xHCI driver
will restore the ERSTBA (Event Ring Segment Table Base Address)
register to be the value before suspending. And at this point,
the old DM implementation will set both er_enq_idx and
er_events_cnt to be zero, so the DM will access the Event Ring

In the process of implementation for USB isochronous transfer, the
timeout (100ms) is not enough for Plantronics USB headset. So pass
longer timeout (300ms) to function libusb_control_transfer will
make USB headset of Plantronics work.
This change only results a longer execution time in ENUMERATION process
for few devices like Plantronics USB headset which need more time to do
its internal operations. For most USB devices, time less than 100ms are
enough to complete the execution of libusb_control_transfer. So basically
it will not affect the whole system performance.
In the long term, a better solution (eg: async control transfer) will be
introduced to replace current implementation.

Current ring buffer processing logic assumes every transaction
will be submited to physical device before next transaction
coming. So it use two states 0 (free) and 1 (used) to represent
the state of every data block in the ring buffer. With the help
of the two state, the ring buffer could accept and process data
normally.
But this logic is not proper for ISOC transfer, which generally
submits many transactions even none of them arrive the physical
device. So this patch uses three values to represent the state
of data block in the ring buffer:
USB_XFER_BLK_FREE: this block could be filled with new data;
USB_XFER_BLK_HANDLING: this block is submited to physical device
but response from device is still not received;
USB_XFER_BLK_HANDLED: this block has been processed by physical
device.
The new logic will do different things for each state, which will
make the ISOC transfer work successfully.

The Intel Trace Hub (aka. North Peak, NPK) is a trace aggregator for
Software, Firmware, and Hardware. On the virtualization platform, it
can be used to output the traces from SOS/UOS/Hypervisor/FW together
with unified timestamps.
There are 2 software visible MMIO space in the npk pci device. One is
the CSR which maps the configuration registers, and the other is the
STMR which is organized as many Masters, and used to send the traces.
Each Master has a fixed number of Channels, which is 128 on GP. Each
channel occupies 64B, so the offset of each Master is 8K (64B*128).
Here is the detailed layout of STMR:
M=NPK_SW_MSTR_STP (1024 on GP)
+-------------------+
| m[M],c[C-1] |
Base(M,C-1) +-------------------+
| ... |
+-------------------+
| m[M],c[0] |
Base(M,0) +-------------------+
| ... |
+-------------------+
| m[i+1],c[1] |
Base(i+1,1) +-------------------+
| m[i+1],c[0] |
Base(i+1,0) +-------------------+
| ... |
+-------------------+
| m[i],c[1] |
Base(i,1)=SW_BAR+0x40 +-------------------+
| m[i],c[0] | 64B
Base(i,0)=SW_BAR +-------------------+
i=NPK_SW_MSTR_STRT (256 on GP)
CSR and STMR are treated differently in npk virtualization because:
1. CSR configuration should come from just one OS, instead of each OS.
In our case, it should come from SOS.
2. For performance and timing concern, the traces from each OS should
be written to STMR directly.
Based on these, the npk virtualization is implemented in this way:
1. The physical CSR is owned by SOS, and dm/npk emulates a software
one for the UOS, to keep the npk driver on UOS unchanged. Some CSR
initial values are configured to make the UOS npk driver think it
is working on a real npk. The CSR configuration from UOS is ignored
by dm, and it will not bring any side-effect. Because traces are the
only things needed from UOS, the location to send traces to and the
trace format are not affected by the CSR configuration.
2. Part of the physical STMR will be reserved for the SOS, and the
others will be passed through to the UOS, so that the UOS can write
the traces to the MMIO space directly.
A parameter is needed to indicate the offset and size of the Masters
to pass through to the UOS. For example, "-s 0:2,npk,512/256", there
are 256 Masters from #768 (256+512, #256 is the starting Master for
software tracing) passed through to the UOS.
CSR STMR
SOS: +--------------+ +----------------------------------+
| physical CSR | | Reserved for SOS | |
+--------------+ +----------------------------------+
UOS: +--------------+ +---------------+
| sw CSR by dm | | mapped to UOS |
+--------------+ +---------------+
Here is an overall flow about how it works.
1. System boots up, and the npk driver on SOS is loaded.
2. The dm is launched with parameters to enable npk virtualization.
3. The dm/npk sets up a bar for CSR, and some values are initialized
based on the parameters, for example, the total number of Masters for
the UOS.
4. The dm/npk sets up a bar for STMR, and maps part of the physical
STMR to it with an offset, according to the parameters.
5. The UOS boots up, and the native npk driver on the UOS is loaded.
6. Enable the traces from UOS, and the traces are written directly to
STMR, but not output by npk for now.
7. Enable the npk output on SOS, and now the traces are output by npk
to the selected target.
8. If the memory is the selected target, the traces can be retrieved
from memory on SOS, after stopping the traces.

To access a device region, the driver writes into the capability

- The driver sets the BAR to access by writing to cap.bar
- The driver sets the size of the access by writing 1, 2 or 4 to
cap.length
- The driver sets the offset within the BAR by writing to cap.offset
At that point, pci_cfg_data will provide a window of size cap.length

This patch refines the ACRN dm directory architecture.

For platform architecture depended files, create arch/ under root dir.

Thus, char *config will change from:

to:
/XXXX_vdisk_file
and char *b will point to:

So, the range will never take effect for virtio-blk.

IOC mediator communicates with native IOC HW through several native channels of
CBC protocol. And IOC mediator communicates with virtual UART through one virtual
channel.
This patch implements channel operations including open/close/read/write.

IOC mediator main functionality is transfer data between native CBC char
devices and virtual UART, it is implemented as full virtualization, Guest
OS can reuse native CBC driver directly.

Unlike kqueue/kevent of BSD, the epoll of Linux could be
add/del by using different API on the fly.
This patch drops the notify used by mevent_add/del and
call epoll_ctl to add/delete target fd. Only keeps
global_head to track mevent added and makes the code
logic in mevent_dispatch() a littel bit simpler.
Another thing is related with epoll_ctl. If the target
fd is regular fd which doesn't support epoll, epoll_ctl
will return -1. When DM is start by systemd, the STDIO
is not mapped to terminal, epoll_ctl on STDIO could
return -1. Which block UOS boot. We only call mevent_add
after confirm STDIO is mapped to terminal.

There are two build issues:
- add -fno-strict-aliasing to address
error: dereferencing type-punned pointer will break strict-aliasing rules
- initialize tfd to zero to address
error: ‘tfd’ may be used uninitialized in this function

After this patch reverted, UOS launched successfully.
Firmware need to disconnect the client connection when host's message
overlow the receive buffer in firmware. We emulate this behavior in
backend service.

Now, we treat a read/write ENODEV error as a firmware reset. When MEI
reset happens in driver, we need disconnect all active clients and
restart HBM flow.

HECI Bus Message is important for HECI clients communication. They use
HBM for connect, disconnect, get property and so on. In backend service,
we need do some emulation for HBM as we are running on top of native
MEI driver.

Backend service access the native HECI driver through MEI driver
interface in service OS. Some MEI clients need to be multiplexed,
the backend service will engage necessary service at clients filter.
TX thread is for passing data from guest to host MEI driver, then to
native hardware. RX thread is for passing data from native hardware to
guest.
