- fixed bochsrc line after a "raw byte" string parameter
- changed parameter name "macaddr" to "mac" (same as bochsrc option parameter)
- skip disabled parameters when building the bochsrc line
- added "multiline" switch to select the output format (one or multiple lines)
- renamed siminterface method and use it in the network devices code
I observed ~5% emulation slowdown ... thinking about possible mitigations
this fixes TLB issue with SMAP and SMEP features.
these features introduce a new behavior when page can be inaccessible by System (CPL=0).
Current behavior is accessBits was not supporting it but legacy (from Bochs 2.3.6) was.
The wrong behavior can be observed if user access a user page and system access the same page later.
user access is fine and pass SMEP/SMA checks and stores the translation in TLB.
the system access will hit the TLB and nobody could detect that system cannot access that page.
- renamed config parameter "i440fx_support" to "enabled"
- new config parameter "chipset" added (current choices "i430FX" and "i440FX")
- don't load ACPI support if the i430FX chipset is selected
- select register values for the core PCI devices depending on the chipset
- USB UHCI must be connected to a PCI slot if the i430FX chipset is used
- rombios changes to make the i430FX chipset work
- TODO #1: implement limitation to 1 cpu and 128 MB RAM for the i430FX chipset
- TODO #2: verify register behaviour of both chipsets
- read PCI confAddr value from the devices code for debugger output
- PCI confData value isn't needed at all (changes by each read / write access)
- PCI framework methods don't need to be virtual
- PCI slot configuration, memory and i/o BAR registration, PCI i/o space
handlers now present in devices.cc
- configure: E1000 emulation and USB support need PCI
- vga: fixes for the non-PCI case
I am copiling using Cygwin+mingw and cnfigure script by default doesn't find and GUI library and therefore I supply --with-win32.
But seems it is not enough to get GUI debugger compiled - Makefile was missing win32_enh_dbg_osdep.cc
