- added a hack to make EHCI work in Bochs, but without asynchronous packet
support (tested with "high-speed" USB disk).
- added missing list for connected USB device state.
- fixed some of the endianness issues
- fixed some of the GCC warnings
- changed some BX_INFO to BX_DEBUG
- FIXME: non-bulk devices not yet working on xHCI. Linux guest hangs during boot
when HID or hub device is connected.
instead of the hub's remove_device() method. The external hub removes connected
devices before clearing it's own list. This fixes crash on exit when devices
are present on external hub.
ignores connected high speed device (fixes panic with EHCI on guest OS init or
shutdown). The other HC's now panic and disconnect device if the user decides
to continue.
Asynchronous transfers are not yet working properly (tested with USB disk device
in high speed mode). That's why the support for "speed:high" is still disabled.
Since we have no test case for the isosynchronous mode, I have not yet ported
the main code for it.
- added Android case to the configure script.
- renamed file memory.h to memory-bochs.h to fix conflict with NDK.
- fixed Android issues in some files.
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.
- 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.
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.
- 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.
sector transfers (buffer pointer update was missing). Multiple sectors transfers
could for the USB disk emulation and for image conversion with bximage.
- More accurate seek emulation for read commands.
- Moved status indicator code to the SCSI layer.
- Fixed dump size for async packets.
TODO: Seek emulation for disk write commands.
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.
- Added missing update of the write protection flag after runtime config.
- Added sense codes for invalid cases of some commands.
- Added buffer pointer save/restore handling and use BXRS macros now.
It can be used when asynchronous packet handling is available. Some changes in
the non-async read and write code.
TODO: sector write timing, seek timing (similar to legacy floppy).
- deactivate seek timer when operation is cancelled.
- set async packet mode with a separate method at connection time.
- renamed some variables and prepared seek emulation for USB disk writes.
MSD / SCSI code.
TODO list (async packet and seek support):
- seek emulation for USB harddisk write commands
- seek emulation for floppy
- async packet support for UHCI and xHCI
- improve and clean up OHCI async packet code
- Common USB code prepared for async USB packet handling (ported from an earlier
Qemu version).
- Added simple async packet handling to OHCI (partly ported from earlier Qemu).
- Implemented USB cdrom seek emulation for hubs with async packet support. The
legacy code is still present for hubs without this feature.
- For UHCI and xHCI the callback is set to NULL to force the usage of the
legacy cdrom read code.
TODO: clean up OHCI code, async support for UHCI and xHCI, seek emulation for
USB harddisk and floppy.
- rewrite of usb_dump_packet(), execute code only if debug output is enabled.
- OHCI: removed packet dump, it should be done in the devices code if necessary.
