8bbcc7c65e Save / restore: renamed register methods of device cores (fixes warnings in
FreeBSD gcc 9.3).

76b54ecb61 Renamed bx_pci_device_stub_c to bx_pci_device_c and derive it now from class
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.

d46a9b7205 Some work on the PCI 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.

c3b608a3c9 Implemented USB remote wakeup mechanism.
- Extended USB callback definition to support different event types sent from
  device to HC. Currently we only have the two events "async completion" and
  "remote wakeup".
- Implemented event handlers in the UHCI, OHCI and EHCI. For the EHCI version
  we currently have no test case.
- The external USB hub now uses this feature at device connect/disconnect.
  Now the device change on the hub is correctly detected by the guest OS.
- TODO #1: remote wakeup and async completion for the xHCI.
- TODO #2: event handler for the external hub to make a USB device work on
  a chain of hubs.
- TODO #3: the event handler possibly could be used for the packet copy code.

185ae80925 Some USB code changes by Ben Lunt
- 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.

a22e66ef13 Added support for multiple async packets on OHCI.
- Moved UHCI async packet functions to usb_common.h for using then on both
  UHCI and OHCI.
- Modified OHCI packet handling based on the UHCI implementation.
- Renamed EHCI helper function to avoid conflicts.
- TODO: async packet support on xHCI.

f82bb13f88 Added support for multiple async packets on UHCI (TODO: other HCs). 2016-11-22 18:06:44 +00:00

0192554c25 Started rewrite of USB packet handling required for full async packet support.
Step #1: Allocate buffer for data transfers dynamicly with the required size
(done in UHCI, OHCI and EHCI).

de6ee1d7eb Added basic async packet support in the UHCI core. Only one async operation
is currently supported per hub at the same time (same as OHCI).
TODO #1: We should support at least one async operation per connected device.
TODO #2: Async packet support for EHCI and xHCI.

5e635a87bb Fixed IRQ sharing for multi-function PCI devices and removed workaround in the
UHCI core code.

e19f28dad7 Call DEV_pci_set_irq() only if the IRQ level really changes. The Bochs IRQ
routing code is possibly buggy, since it can make multiple UHCI devices fail
in a multi-function device (like EHCI).

2f94f55a82 Some work in the UHCI core for the usage as a companion controller of EHCI.
- added method to change port ownership.
- fixed UHCI reset and initialized device pointers.
- added symbol UHCI_FULL_DEBUG to reduce debug output if not set.
- renamed connection handling method.

d455659bd1 Split the USB UHCI code in two parts: uhci_core.cc implements the device
emulation and usb_uhci.cc implements the setup for the PIIX3 chipset and the
runtime device change code. The UHCI core is required for the EHCI emulation,
since there can be multiple "companion" controllers for USB 1.1 device handling.
