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.
