- Disable port "options" parameter after successful connect. While connected,
a device may install runtime options to control it's behaviour.
- Added enable handlers for the "options" parameter to ensure an attempt to
change the device while connected doesn't enable it.
- Some related code cleanups.
- USB hub: disable device "options" parameter if device is set to "none".
- USB hub: handle device disconnect in runtime_config().
- Removed handling of USB device type in host controllers and external hub.
- bx_shadow_bool_c: removed unused bitnum feature and changed data type.
- Changed return type of memory handlers to bool.
- Modified virtual timer, PIC and PIT code.
bx_devmodel_c. The early version of the combined vga / svga_cirrus code
required the now obsolete implementation. Some related cleanups in the
devices code.
- Since the pci_read_handler() method is identical in most devices, move it
to the base class to reduce code duplication. Only the 'pcidev' device has
it's own implementation (NOTE: it is not maintained yet).
- Minor other fixes and cleanups in some PCI devices.
- 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.
- USB xHCI NAK handling fix by Ben. Now openSUSE 13.2 boots without hang with
hub connected to an xHCI port.
- Updated Ben's email address and year in some copyright headers.
- Get rid of device_buffer and use packet init / cleanup functions.
- Read immediate data from memory location instead of possibly byte-swapped
TRB parameter.
devices like USB disk, cdrom or floppy. Using this feature for the new USB
floppy. Removed static indicators for port activity from the USB HC code.
TODO: Implement status LEDs for USB disk and cdrom.
Notes by Ben:
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.
NOTE: The Windows driver for this device uses a proprietary detection
mechanism and we don't have the permission to implement it. That's why it only
works fine with non-Windows guests.
