Jian Jun Chen 781e7dfb29 dm: virtio: rename virtio ring structures and feature bits
Some virtio ring structures and virtio feature bits are using the
same name/definition as those in kernel header files(linux/
virtio_ring.h, linux/virtio_config.h). Kernel header files must
be included to perform ioctls to support vhost. There are
compiling errors due to duplicated definitions. In this patch
the following renamings are done:

VRING_DESC_F_NEXT -> ACRN_VRING_DESC_F_NEXT
VRING_DESC_F_WRITE -> ACRN_VRING_DESC_F_WRITE
VRING_DESC_F_INDIRECT -> ACRN_VRING_DESC_F_INDIRECT

VRING_AVAIL_F_NO_INTERRUPT -> ACRN_VRING_AVAIL_F_NO_INTERRUPT
VRING_USED_F_NO_NOTIFY -> ACRN_VRING_USED_F_NO_NOTIFY

VIRTIO_F_NOTIFY_ON_EMPTY -> ACRN_VIRTIO_F_NOTIFY_ON_EMPTY
VIRTIO_RING_F_INDIRECT_DESC -> ACRN_VIRTIO_RING_F_INDIRECT_DESC
VIRTIO_RING_F_EVENT_IDX -> ACRN_VIRTIO_RING_F_EVENT_IDX
VIRTIO_F_VERSION_1 -> ACRN_VIRTIO_F_VERSION_1

vring_avail -> virtio_vring_avail
vring_used -> virtio_vring_used
vring_size -> virtio_vring_size

Jie Deng f37588505b dm: virtio_net: remove netmap/vale backend support
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.

This is temperory workaround for DM crash when doing fastboot
reboot. In fastboot, it will disable USB host functionality by
disable device respsone to one PCI bar. While DM code just release
the bar in this case. Which break the reboot functionality.

The workaround is to remove the assert to avoid DM abort. This is
safe because reboot will remove all memory range registered.

We will have offiical fixing later.

Liang Yang 612037e138 DM USB: xHCI: enable Flat Mode Hub emulation support.
Flat Mode for hub emulation means DM emulates USB devices under hub but
hide hub itself. Under this design the Guest OS cannot see any emulated
hub. So in the perspective of Guest OS, all the emulated devices are
under root hub.

This patch is used to enable feature as mentioned above. And please NOTE,
it is the initial version of hub flat Mode hub emulation, there are one
limitation: only one physical hub is supported. If second physical hub is
connected, the connect and disconnect behavior in second hub may affect
the function of first emulated hub.

The USB HUB device model should be the final long term solution, but it is
very complex. Use flat mode HUB emulation as the short term solution first
to support some USB touch devices which integrated internal HUB.

Jian Jun Chen f1e87f60fc dm: vrtc: use signalfd to poll signal from timer
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.

Xiaoguang Wu 0b405ee780 DM USB: xHCI: change flow of creation of virtual USB device
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
from the start position in the buffer. But at the same time the
UOS xHCI driver still wants to access the old position in the
Event Ring before suspending, which will result of unexpected

Xiaoguang Wu b95f93927b DM USB: temporary solution for corner case of control transfer
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.

Xiaoguang Wu 640d896508 DM USB: change TRB ring processing logic for ISOC transfer
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.

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.

Jian Jun Chen c001911e19 dm: virtio: support virtio 1.0 PCI configuration access capability
The VIRTIO_PCI_CAP_PCI_CFG capability creates an alternative access
method to the common configuration, notification, ISR and device-
specific configuration regions.

To access a device region, the driver writes into the capability
structure (ie. within the PCI configuration space) as follows:

- 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
into the given cap.bar at offset cap.offset.

Yu Wang 8c06b69622 dm: Reorganize ACRN DM directory.
The current dm, all non-pci and non-acpi related files are put into
hw/platform directory. This is actually disturbed the meaning of
*platform*. The platform devices are mean of board and SoC specific
non-PCI devices, like usb devices, etc.

This patch refines the ACRN dm directory architecture.

For some common device logic files, likes block_if.c/uart_core.c or
usb_core.c. They will move to hw/ directly.

For platform architecture depended files, create arch/ under root dir.
And create sub-dir arch/x86 for x86 architecture, will create more
architectures in future. The pm.c will move to this new dir.

The hw/acpi will be moved to hw/platform/acpi due to acpi also be

The original code assume there is only one configuration for
virtio-blk, and 'b' is just located after that configuration,
so to get the value of 'b', it will end char *config by adding
'\0' after the first configuration.

Thus, char *config will change from:
  /XXXX_vdisk_file,range=xxx/xxx
to:
  /XXXX_vdisk_file
and char *b will point to:
  range=xxx/xxx
So, the range will never take effect for virtio-blk.

Now, 'b' is designed to located just after emul, and
char *config will point to all configurations after 'b'.

Note: only ",b," is taken for boot device option.

Liu Yuan 61db2c78cc IOC mediator: support IOC lifecycle
This patch implements the IOC lifecycle virtualization.

In native environment, lifecycle is uesed for SoC system power control,
likes enter/exit S3/S5. So these related messages can not forward directly
between physical IOC and Guest OS, they need to be mapped to VM pause, exit
and launch.

Yin Fengwei c6bf67543c DM: mevent_add/del refine for Linux
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.
