9557cafcef revertng commit #12854 because it broke MT simulation with debugger enabled. Until investigted. 2015-12-20 22:44:54 +00:00

f5d094024d Started implementing USB EHCI support. The PCI and MMIO register behaviour is 
almost implemented, the port owner handling and the UHCI companion controllers
are present. High speed devices are not yet supported, since the EHCI scheduler
code has not been written yet (e.g. porting from Qemu). Low and full speed
devices should be detected correctly and work after port ownership change to
UHCI. 6 ports are available and the bochsrc syntax is similar to other HCs.

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

93f9584b1b Load USB core plugin before parsing bochsrc, since USB HC devices depend on 
it's symbols. Unload this plugin in the devices init if unused.
TODO: Similar changes may be required for the networking and sound stuff.

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.

7d56f7d1d5 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.

56a7b11ab5 Align PCI memory regions at 64k boundary to make Bochs memory handlers work 
correctly (registering small MMIO regions of USB controllers could fail otherwise).

c2b790809d Simplify xHCI code, since the capability registers are readonly. 
- Moved initialization from reset_hc() to init().
- Removed save/restore registration.
- Removed extra debug output.

cbd147fca3 Fixed and improved text mode CO40. 
- vgacore: double font and screen width at half dot clock.
- X gui: improved font bitmap generation to support width > 9.
- win32 gui: adjust values to use existing stretching feature.
- guis rfb, sdl, sdl2, vncsrv and wx: double pixels if font width > 9.

c3397b15d7 Fixed read() and write() methods of most disk images modes to support multiple 
sector transfers (buffer pointer update was missing). Multiple sectors transfers
could for the USB disk emulation and for image conversion with bximage.

708e946cb8 As a workaround for possibly buggy hdimage code, read() and write() calls 
transfer only one disk sector. Moved disk write code to the seek_complete()
method (seek emulation for write commands is not ready yet).

256fd99d12 USB floppy "format unit" timing implemented similar to read/write timing. 
Added latency time for the "implied seek" of read/write/format commands. Both
features can be used when asynchronous packet handling is available. Some
related changes in the non-async read and write code.
