The default value is 5, setting quantum to 15 could improve emulation speed by 20-50%. bochsrc CPU option to get SMP emulation faster. BTW, for SMP configuration you could try to use large 'quantum' values in. It could be good idea to get some explanation from first hands why things done this way and not another. bochsrc:Īnyway, it is probably good idea to write about it in Bochs-Developers mailing to drive Volker's attention. The port_e9_hack stuff printed from 'unmapped' device which is, I think, not necessary enabled by default now. I guess it might be realted to Volker's recent changes in plugins architecture. One more thing: Have there been any changes to the 'port e9 hack' for debugging output? I used to print some debug output to port e9 (and enabled it in my bochsrc file with 'port_e9_hack: enabled=1') and it used to work fine, but with the new version I don't get any output. added 'nokeyrepeat' option for the SDL and win32 gui bochsrc option parsing (patch from fix for bug: Crash on WIN2K - ID: 3454214 bochsrc option to control VMX support on runtime Config interface / GUI and display libraries removed devices 'acpi', 'ioapic' and 'pci_ide' from optional plugin control USB UHCI: some fixes to make it work in XP guest VVFAT: several fixes in the optional write support (passes test with XP) fixed possible failures of PCI DMA transfers removed very old deprecated configure options from configure script added missing dependencies for cdrom_osx.o fixed compilation issue under win32 -with-nogui fixed compilation err with x86 hw breakpoint enabled and CPU_LEVEL < 6 fixed compilation err in instrumentation call () instrumentation: added special indication for indirect call/jump fixed typo - closing SF bug step all command fails in SMP mode Better report of supported CPUID features when not using pre-defined CPUID profile VMX: fixed VirtualBox failures with VMX+EPT enabled VMX: fixed VirtualBox VMX guest Guru Meditation - FS.BASE got corrupted after VMX: fixed Bochs PANIC when doing I/O access crossing VMX I/O permission bitmaps VMX: fixed VMFUNC instruction behavior to align with Intel SDM revision 041
