- use get_dwords() and put_dwords() from EHCI sources for reading / writing xHCI data structures as dword array. This fixes some endianness issues. - simplified copying data from / to data structures since we can now use the dword array with the correct byte order directly. - fixed all remaining "strict-aliasing" GCC warnings.

/* Notes by Ben Lunt:
|
|
* This emulates a NEC/Renesas uPD720202 2-port (2 socket, 4-port register sets)
|
|
* Root Hub xHCI Host Controller.
|
|
* Many, many thanks to Renesas for their work and effort in helping my research.
|
|
*
|
|
* I have tested in with my own tests and WinXP Home Edition SP3.
|
|
*
|
|
* Use port1 and port2 to emulate a Super-speed device, and use port3 and port4
|
|
* to emulate Low-, Full-, or High-speed devices.
|
|
*
|
|
* Examples:
|
|
* usb_xhci: enabled=1, port3=disk:"usbdisk.img", options3=speed:low
|
|
* usb_xhci: enabled=1, port3=disk:"usbdisk.img", options3=speed:full
|
|
* usb_xhci: enabled=1, port3=disk:"usbdisk.img", options3=speed:high
|
|
* usb_xhci: enabled=1, port1=disk:"usbdisk.img", options1=speed:super
|
|
*
|
|
* Currently, only a USB MSD Thumb Drive device is emulated as a Super-speed device.
|
|
* All other emulated devices are Low- or Full-speed devices.
|
|
*
|
|
* This code is 32- and 64-bit addressing aware (uses: bx_phy_address & ADDR_CAP_64)
|
|
*
|
|
* This emulation is coded with the new registers of xHCI version 1.10. However,
|
|
* nothing more has been done to emulate 1.10 features. YET.
|
|
* This emulation is set with VERSION_MAJOR and VERSION_MINOR, 0x01 and 0x10
|
|
* respectively.
|
|
*
|
|
* This emulation is experimental. It is not completly accorate, though it is
|
|
* my intention to make it as close as possible. If you find an error or would
|
|
* like to add to the emulation, please let me know at fys [at] fysnet [dot] net.

/* This is the Save/Restore part of the controller. The host will issue a save state

|

* will use the scratch pad buffers (or its own memory if HCSPARAMS2:ScratchPadRestore == 0)
|
|
* to save its internal state before power shutdown (hibernation). If the SPR bit is set,
|
|
* the controller is to use the scratch pad buffers and the host is to make sure these
|
|
* buffers are maintained during hibernation. (The host may use paging to page to disk
|
|
* before hibernation as long as the memory is updated from the paged to disk before
|
|
* the restore is performed.)
|
|
*
|
|
* Since a Bochs power hibernation does not touch our current state, there would be no
|
|
* need to save the controller state. However, the host may (just might) check to see
|
|
* if the scratch pad buffers have been modified (due to paging and/or protection), so
|
|
* we need to write something to these buffers.
|
|
*
|
|
* We will simply save 'BX_XHCI_THIS hub' to the scratch pad buffers. However, since we
|
|
* use bx_bool's for bits, which are 32-bits for every single bit of the controller,
|
|
* 'hub' is way too big to fit in the scratch pad buffers. Therefore, we will only
|
|
* save up to PAGESIZE * BUFFER_COUNT.
|
|
*
|
|
* We will also use a simple crc check and store this as the last dword in each buffer.
|
|
* This way, when we restore, we can check to see if we restored the correct data and
|
|
* set the restore error bit accordingly.
|
|
*
|
|
* Please note that we must not assume that the scratch pad buffers will be in
|
|
* consecutive order, one right after the other, in memory.
|
|
*
|
|
* Callee checks to be sure the Halted bit is set first.
|
