Xiaoguang Wu e9211514e7 DM USB: modify disconnecting logic to support Windows 10
The Windows 10 feeds back quicker than Linux OS when error occured
due to device disconnecting, it will quickly reset the xHCI controller
before the DM starts to emulate disconnect event and it may cause some
unexpected errors such as crash.

This patch will do one more check when error happens, if the error
is induced by device disconnecting, the DM will not report error and
just wait until the disconnect event is reported to the guest. This
change could produce the correct hehavior as we expected.

Xiaoguang Wu 06781b37e9 DM USB: dynamically allocate block count for struct usb_xfer
The block count of the struct usb_xfer is hard coded by the macro
USB_MAX_XFER_BLOCKS (1024), it wastes memory if 1024 blocks are
allocated for low speed transfer such as control transfer or interrupt
transfer. This patch introduces a new method to allocate different
number of blocks according to different endpoint type.

Xiaoguang Wu 8949a5802a DM USB: introduce struct xhci_block for xHCI emulation
In the struct usb_block, there are some fields such as 'ccs',
'streamid', which should not be seen in the USB layer. This
patch intruduces new struct xhci_block to include the variables
for xHCI emulation.

Xiaoguang Wu 236c23e418 DM USB: introduce enum type usb_block_type
In the process of USB data transfer, there three kinds of data blocks:
a. Non data block, which contains some control information;
b. Partial data block, which contains part of a large data chunk;
c. Full data block, which contains a complete data chunk.

In previous implementation, the differences mentioned above are described
by the usb_block::chained. But the 'chained' is concept in the xHCI area
and should not appear in the USB layer. This patch introduces enum type
usb_block_type to replace the 'chained' field in struct usb_block.

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.

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
considered as part of platform.
