- ne2k: replaced debugger command 'info ne2k' completely by a new version based
on 'info device' with additional arguments and removed all of the now obsolete
stuff (ne2k device stub, macro for print_info())
- pci: added option 'dump=full' for the debugger command 'info device' to show
the whole PCI config space
- TODO: some other devices could have support for additional options in
debug_dump()
- removed FILE parameter from print_info() (unused - since dbg_printf() doesn't
need it)
- converted tabs to spaces
- TODO: implement 'info device' with optional arguments to get rid of the
print_info() method
of the device specified in 'string'. Added register mechanism and chained
list to store the device name and pointer. Replace hardcoded debug info
implementations for pic, pci and vga by the new one.
- TODO #1: improve existing debug_dump() output and add more devices
- TODO #2: add support for additional arguments and replace the NE2k print_info()
- IO intercept is not implemented yet
- MSR intercept is not implemented yet
VMX:
Fixed Bochs PANIC crash when doing I/O access crossing VMX I/O permission bitmaps.
This can happen because access_physical_read and access_physical_write cannot access memory cross 4K boundary.
32-bit CPU using Bochs binary compiled with x86-64 support.
The commit also fixes some init.cc issues with initialization of SYSCALL/SYSRET MSR in AMD hosts and also includes code reorg.
SMP emulation. New implementation uses dynamic CPU quantum value and takes
full advantage of the trace cache. Each emulated processor will execute
the whole trace before switching to the next processor.
* It is also safe to use large (up to 16 instructions) quantum values for
the SMP emulation now and improve performance even further.
The same merge also completely fixes SF bug :
[3312237] stepN command might be not working properly
Handlers chaining speedups are also supported with SMP emulation now.
[3298173] Breakpoint on VMEXIT event by Jianan Hao
Patch description:
The patch provides a new command "vmexitbp" to set breakpoint when VM guest exit. The simulation will be stopped before first HOST mode instruction is executed.
Usage:
Type "vmexitbp" in debugger command window to switch it on/off (similar to modebp).
Currently, the patch has no corresponding interface on GUI debugger. Someone may add it if interested.
