* renamed CPU_ID to BX_CPU_ID.
with this new name there is no possibility for name contentions and BX_CPU_ID
definition could be moved out to NEED_CPU_REG_SHORTCUTS block
* returned back `unsigned BX_CPU::which_cpu(void)` function
* added BX_CPU_ID parameter for
BX_INSTR_PHY_READ(a20addr, len);
BX_INSTR_PHY_WRITE(a20addr, len);
now it will be
BX_INSTR_PHY_READ(cpu_id, a20addr, len);
BX_INSTR_PHY_WRITE(cpu_id, a20addr, len);
It uses special gcc attribute regparm, available on gcc3.2 on x86.
I get about 7% increase when booting windows 95.
The patch still need some integration work before being included
in the main code.
- function userbutton_handler(): stop parsing the shortcut string if the
key name is invalid
- function userbutton_handler(): incrementing variable 'len' simplified
- function snapshot_checker(): fixed a warning
> CPU_ID is defined as
> #define CPU_ID (BX_CPU_THIS_PTR local_apic.get_id())
> This is not true when the APIC name is changed (true in Linux). Please
> change this to:
> #define CPU_ID (BX_CPU_THIS - BX_CPU(0))

Comment from the author:
Attached is a "patch" file detailing what you need to do
to add USB support (UHCI only for now) to your existing
Bochs (2.0.xx) source code.
I use Win32 and VC++ but the source and modifications
should be platform and compiler independant.
Please let me know if this patch some how breaks the
build process of your compilation (Bochs 2.0.0 or above
only).
I would also like any feedback on how this code works
(or doesn't work) on your platform and within your
images. If you explain in as much detail as you can on
how it did or did not work, I will try to add to the source
to help it work on all platforms and images.
- added "ioaddr" and "irq" to the "usb1" bochsrc option
- number of ports is limited to 2 for a USB UHCI root hub
- the PCI configuration space is now a part of the usb hub structure
- new symbol BX_USE_PCIVGA_SMF for the experimental PCI VGA device
- pcivga.cc: removed unnecessary include statement
- pcivga.cc: fixed two warnings
- pcivga.h: removed unnecessary symbol BX_IODEV_PCIVGA_H
