| # CONFIG_INTERFACE |
| # |
| # The configuration interface is a series of menus or dialog boxes that |
| # allows you to change all the settings that control Bochs's behavior. |
| # There are two choices of configuration interface: a text mode version |
| # called "textconfig" and a graphical version called "wx". The text |
| # mode version uses stdin/stdout and is always compiled in. The graphical |
| # version is only available when you use "--with-wx" on the configure |
| # command. If you do not write a config_interface line, Bochs will |
| # choose a default for you. |
| # |
| # NOTE: if you use the "wx" configuration interface, you must also use |
| # the "wx" display library. |
| #======================================================================= |
| config_interface: textconfig |

| #======================================================================= |
| # DISPLAY_LIBRARY |
| # |
| # The display library is the code that displays the Bochs VGA screen. Bochs |
| # has a selection of about 10 different display library implementations for |
| # different platforms. If you run configure with multiple --with-* options, |
| # the display_library command lets you choose which one you want to run with. |
| # If you do not write a display_library line, Bochs will choose a default for |
| # you. |
| # |
| # The choices are: |
| # x use X windows interface, cross platform |
| # win32 use native win32 libraries |
| # carbon use Carbon library (for MacOS X) |
| # beos use native BeOS libraries |
| # macintosh use MacOS pre-10 |
| # amigaos use native AmigaOS libraries |
| # sdl use SDL library, cross platform |
| # svga use SVGALIB library for Linux, allows graphics without X11 |
| # term text only, uses curses/ncurses library, cross platform |
| # rfb provides an interface to AT&T's VNC viewer, cross platform |
| # wx use wxWindows library, cross platform |
| # nogui no display at all |
| # |
| # NOTE: if you use the "wx" configuration interface, you must also use |
| # the "wx" display library. |

| # IPS: |
| # Emulated Instructions Per Second. This is the number of IPS that bochs |

| # |
| # IPS is used to calibrate many time-dependent events within the bochs |

| # updates, the duration of time before a key starts to autorepeat, and |
| # the measurement of BogoMips and other benchmarks. |
| # |
| # Examples: |
| # Machine Mips |
| # ________________________________________________________________ |
| # 650Mhz Athlon K-7 with Linux 2.4.4/egcs-2.91.66 2 to 2.5 Mips |
| # 400Mhz Pentium II with Linux 2.0.36/egcs-1.0.3 1 to 1.8 Mips |

| # LOG CONTROLS |
| # |
| # Bochs now has four severity levels for event logging. |
| # panic: cannot proceed. If you choose to continue after a panic, |
| # don't be surprised if you get strange behavior or crashes. |
| # error: something went wrong, but it is probably safe to continue the |
| # simulation. |
| # info: interesting or useful messages. |
| # debug: messages useful only when debugging the code. This may |
| # spit out thousands per second. |
| # |
| # For events of each level, you can choose to crash, report, or ignore. |
| # TODO: allow choice based on the facility: e.g. crash on panics from |
| # everything except the cdrom, and only report those. |
| # |
| # If you are experiencing many panics, it can be helpful to change |
| # the panic action to report instead of fatal. However, be aware |
| # that anything executed after a panic is uncharted territory and can |
| # cause bochs to become unstable. The panic is a "graceful exit," so |
| # if you disable it you may get a spectacular disaster instead. |

| # COM1: |
| # This defines a serial port (UART type 16550A). You can specify a device |
| # to use as com1. This can be a real serial line, or a pty. To use a pty |
| # (under X/Unix), create two windows (xterms, usually). One of them will |
| # run bochs, and the other will act as com1. Find out the tty the com1 |
| # window using the `tty' command, and use that as the `dev' parameter. |
| # Then do `sleep 1000000' in the com1 window to keep the shell from |
| # messing with things, and run bochs in the other window. Serial I/O to |
| # com1 (port 0x3f8) will all go to the other window. |
| #======================================================================= |
| #com1: enabled=1, dev=/dev/ttyp9 |
| #======================================================================= |
| # PARPORT1: |
| # This defines a parallel (printer) port. When turned on and an output file is |
| # defined the emulated printer port sends characters printed by the guest OS |
| # into the output file. On some platforms a device filename can be used to |
| # send the data to the real parallel port (e.g. "/dev/lp0" on Linux, "lpt1" on |
| # win32 platforms). |
| # |
| # Examples: |
| # parport1: enabled=1, file="parport.out" |
| # parport1: enabled=1, file="/dev/lp0" |
| # parport1: enabled=0 |
| #======================================================================= |
| parport1: enabled=1, file="parport.out" |

| # SB16: |
| # This defines the SB16 sound emulation. It can have several of the |
| # following properties. |
| # All properties are in the format sb16: property=value |
| # midi: The filename is where the midi data is sent. This can be a |
| # device or just a file if you want to record the midi data. |
| # midimode: |
| # 0=no data |
| # 1=output to device (system dependent. midi denotes the device driver) |
| # 2=SMF file output, including headers |
| # 3=output the midi data stream to the file (no midi headers and no |
| # delta times, just command and data bytes) |
| # wave: This is the device/file where wave output is stored |
| # wavemode: |
| # 0=no data |
| # 1=output to device (system dependent. wave denotes the device driver) |
| # 2=VOC file output, incl. headers |
| # 3=output the raw wave stream to the file |
| # log: The file to write the sb16 emulator messages to. |
| # loglevel: |
| # 0=no log |
| # 1=only midi program and bank changes |
| # 2=severe errors |
| # 3=all errors |
| # 4=all errors plus all port accesses |
| # 5=all errors and port accesses plus a lot of extra info |
| # dmatimer: |
| # microseconds per second for a DMA cycle. Make it smaller to fix |
| # non-continous sound. 750000 is usually a good value. This needs a |
| # reasonably correct setting for IPS. |
| # |
| # For an example look at the next line: |
| #======================================================================= |
| #sb16: midimode=1, midi=/dev/midi00, wavemode=1, wave=/dev/dsp, loglevel=2, log=sb16.log, dmatimer=600000 |
| #======================================================================= |
| # VGA_UPDATE_INTERVAL: |
| # Video memory is scanned for updates and screen updated every so many |
| # virtual seconds. The default is 300000, about 3Hz. This is generally |
| # plenty. Keep in mind that you must tweak the 'ips:' directive |
| # to be as close to the number of emulated instructions-per-second |
| # your workstation can do, for this to be accurate. |
| # |
| # Examples: |
| # vga_update_interval: 250000 |
| #======================================================================= |
| vga_update_interval: 300000 |
| # using for Winstone '98 tests |
| #vga_update_interval: 100000 |
| #======================================================================= |
| # KEYBOARD_SERIAL_DELAY: |
| # Approximate time in microseconds that it takes one character to |
| # be transfered from the keyboard to controller over the serial path. |
| # Examples: |
| # keyboard_serial_delay: 200 |
| #======================================================================= |
| keyboard_serial_delay: 250 |
| #======================================================================= |
| # KEYBOARD_PASTE_DELAY: |
| # Approximate time in microseconds between attempts to paste |
| # characters to the keyboard controller. This leaves time for the |
| # guest os to deal with the flow of characters. The ideal setting |
| # depends on how your operating system processes characters. The |
| # default of 100000 usec (.1 seconds) was chosen because it works |
| # consistently in Windows. |
| # |
| # If your OS is losing characters during a paste, increase the paste |
| # delay until it stops losing characters. |
| # |
| # Examples: |
| # keyboard_paste_delay: 100000 |
| #======================================================================= |
| keyboard_paste_delay: 100000 |
| #======================================================================= |
| # FLOPPY_COMMAND_DELAY: |
| # Time in microseconds to wait before completing some floppy commands |
| # such as read/write/seek/etc, which normally have a delay associated. |
| # I had this hardwired to 50,000 before. |
| # |
| # Examples: |
| # floppy_command_delay: 50000 |
| #======================================================================= |
| floppy_command_delay: 500 |
| #======================================================================= |
| # MOUSE: |
| # This option prevents Bochs from creating mouse "events" unless a mouse |
| # is enabled. The hardware emulation itself is not disabled by this. |
| # You can turn the mouse on by setting enabled to 1, or turn it off by |
| # setting enabled to 0. Unless you have a particular reason for enabling |
| # the mouse by default, it is recommended that you leave it off. |
| # You can also toggle the mouse usage at runtime (middle mouse button on |
| # X11 and SDL, F12 on Win32). |

| # Examples: |
| # mouse: enabled=1 |
| # mouse: enabled=0 |
| #======================================================================= |
| mouse: enabled=0 |
| #======================================================================= |
| # private_colormap: Request that the GUI create and use it's own |
| # non-shared colormap. This colormap will be used |
| # when in the bochs window. If not enabled, a |

| # Examples: |
| # private_colormap: enabled=1 |
| # private_colormap: enabled=0 |
| #======================================================================= |
| private_colormap: enabled=0 |
| #======================================================================= |
| # fullscreen: ONLY IMPLEMENTED ON AMIGA |

| #======================================================================= |
| # ne2k: NE2000 compatible ethernet adapter |
| # |
| # Examples: |
| # ne2k: ioaddr=IOADDR, irq=IRQ, mac=MACADDR, ethmod=MODULE, ethdev=DEVICE, script=SCRIPT |
| # |
| # ioaddr, irq: You probably won't need to change ioaddr and irq, unless there |
| # are IRQ conflicts. |
| # |
| # mac: The MAC address MUST NOT match the address of any machine on the net. |
| # Also, the first byte must be an even number (bit 0 set means a multicast |
| # address), and you cannot use ff:ff:ff:ff:ff:ff because that's the broadcast |
| # address. For the ethertap module, you must use fe:fd:00:00:00:01. There may |
| # be other restrictions too. To be safe, just use the b0:c4... address. |
| # |
| # ethdev: The ethdev value is the name of the network interface on your host |
| # platform. On UNIX machines, you can get the name by running ifconfig. On |
| # Windows machines, you must run niclist to get the name of the ethdev. |
| # Niclist source code is in misc/niclist.c and it is included in Windows |

| # KEYBOARD_MAPPING: |
| # This enables a remap of a physical localized keyboard to a |
| # virtualized us keyboard, as the PC architecture expects. |
| # If enabled, the keymap file must be specified. |
| # |
| # Examples: |
| # keyboard_mapping: enabled=1, map=gui/keymaps/x11-pc-de.map |
| #======================================================================= |
| keyboard_mapping: enabled=0, map= |
| #======================================================================= |
| # KEYBOARD_TYPE: |
| # Type of keyboard return by a "identify keyboard" command to the |
| # keyboard controler. It must be one of "xt", "at" or "mf". |
| # Defaults to "mf". It should be ok for almost everybody. A known |
| # exception is french macs, that do have a "at"-like keyboard. |
| # |
| # Examples: |
| # keyboard_type: mf |
| #======================================================================= |
| #keyboard_type: mf |
| #======================================================================= |
| # USER_SHORTCUT: |
| # This defines the keyboard shortcut to be sent when you press the "user" |
| # button in the headerbar. The shortcut string can be a combination of |
| # these key names: "alt", "bksp", "ctrl", "del", "esc", "f1", "f4", "tab" |
| # and "win". Up to 3 keys can be pressed at a time. |
| # |
| # Example: |
| # user_shortcut: keys=ctrlaltdel |
| #======================================================================= |
| #user_shortcut: keys=ctrlaltdel |

| # The following directives are DEPRECATED |
| # Please convert them to the new syntax or remove them |
| # |
| #======================================================================= |
| #======================================================================= |
| # |
| # The DISKC option is deprecated. Use ATA* options instead. |
| # |
| # DISKC: file=, cyl=, heads=, spt= |
| # Point this at a hard disk image file. To create |
| # a hard disk image, try running bximage. It will help you choose the |
| # size and then suggest a diskc line that works with it. |
| # |
| # In UNIX it may be possible to use a raw device as a Bochs hard disk, |
| # but WE DON'T RECOMMEND IT. In Windows there is no easy way. |
| # |
| # Examples: |
| # diskc: file=10M.sample, cyl=306, heads=4, spt=17 |
| # diskc: file=20M.sample, cyl=615, heads=4, spt=17 |
| # diskc: file=30M.sample, cyl=615, heads=6, spt=17 |
| # diskc: file=46M.sample, cyl=940, heads=6, spt=17 |
| # diskc: file=62M.sample, cyl=940, heads=8, spt=17 |
| # diskc: file=112M.sample, cyl=900, heads=15, spt=17 |
| # diskc: file=483M.sample, cyl=1024, heads=15, spt=63 |
| #======================================================================= |
| #diskc: file="30M.sample", cyl=615, heads=6, spt=17 |
| #======================================================================= |
| # |
| # The DISKD option is deprecated. Use ATA* options instead. |
| # |
| # DISKD: |
| # See DISKC above for syntax |
| # |
| # NOTE: diskd and cdromd must not be used together! |
| #======================================================================= |
| #diskd: file="diskd.img", cyl=615, heads=6, spt=17 |
| #======================================================================= |
| # |
| # The CDROMD option is deprecated. Use ATA* options instead. |
| # |
| # CDROMD: |
| # |
| # cdromd: dev=/dev/cdrom, status=inserted |
| # cdromd: dev=/dev/cdrom, status=ejected |
| # cdromd: dev=e:, status=ejected |
| # |
| # In windows, the drive letter + colon notation should be used for cdroms. |
| # Depending on versions of windows and drivers, you may only be able to |
| # access the "first" cdrom in the system. On MacOSX, use path="drive" |
| # to access the physical drive. |
| # |
| # NOTE: diskd and cdromd must not be used together! |
| #======================================================================= |
| #cdromd: dev=D:, status=inserted |
| #cdromd: dev=/dev/cdrom, status=inserted |
| #cdromd: dev="drive", status=inserted |
| #======================================================================= |
| # |
| # The TIME0 directive is DEPRECATED. Use the CLOCK directive instead |
| # |
| # TIME0: |
| # Specifies the start (boot) time of the virtual machine. Use a time |
| # value as returned by the time(2) system call. If no time0 value is |
| # set or if time0 equal to 1 (special case), the simulation will be |
| # started at the current time of the host. |
| # |
| # Examples: |
| # time0: 1 # Now |
| # time0: 315529200 # Tue Jan 1 00:00:00 1980 |
| # time0: 631148400 # Mon Jan 1 00:00:00 1990 |
| # time0: 938581955 # Wed Sep 29 07:12:35 1999 |
| # time0: 946681200 # Sat Jan 1 00:00:00 2000 |
| #======================================================================= |
| #time0: 938581955 |
| #======================================================================= |
| # |
| # The PIT directive is DEPRECATED. Use the CLOCK directive instead |
| # |
| # PIT: |
| # The PIT is the programmable interval timer. It has an option that tries to |
| # keep the PIT in sync with real time. This feature is still experimental, |
| # but it may be useful if you want to prevent Bochs from running too fast, for |
| # example a DOS video game. Be aware that with the realtime pit option, your |
| # simulation will not be repeatable; this can a problem if you are debugging. |
| #======================================================================= |
| #pit: realtime=1 |

| 1. Virtual Address Translation |
| 1.1 Hierarchical 4-level per address space page tables |
| SPARTAN kernel deploys generic interface for 4-level page tables |
| for these architectures: amd64, ia32, mips32 and ppc32. In this |
| setting, page tables are hierarchical and are not shared by |
| address spaces (i.e. one set of page tables per address space). |

| FRAME Physical address of memory frame to which VADDR is mapped |
| On architectures whose hardware has fewer levels, PTL2 and, if need be, PTL1 are |
| left out. TLB-only architectures are to define custom format for software page |
| tables. |
| 1.2 Single global page hash table |
| Generic page hash table interface is deployed on 64-bit architectures without |
| implied hardware support for hierarchical page tables, i.e. ia64 and sparc64. |
| There is only one global page hash table in the system shared by all address |
| spaces. |

| /kernel/branches/falloc_bad/doc/preemption |
|---|
| 0,0 → 1,58 |
| Kernel makes it possible for a thread to be preempted anytime when |
| IRQ's are enabled on local CPU. This arrangement triggers a discussion |
| about its correctness and efficiency. |
| The correctness issue relates to the possibility of preempting a |
| thread holding a spinlock. It is natural to ask whether such a |
| preemption can lead to a deadlock. By proving the following lemma, we |
| will show that deadlock is actually not possible. |
| Lemma: |
| On condition that each spinning lock is always locked on the same |
| CPU priority level (either always with IRQ's disabled or always |
| with IRQ's enabled), otherwise correct code never deadlocks. |
| Proof: |
| Let all assumptions from the lemma hold. |
| Let us further assume that we have encountered a deadlock. |
| We will analyse all likely ways how that could have happened. |
| a) Deadlock happened between two CPUs. This means that there must |
| have been wrong lock-ordering. Code with lock-ordering problems is |
| considered incorrect and contradicts our assumptions. |
| b) Deadlock happened between two threads of execution executing on |
| the same CPU. |
| b1) If one thread of execution was servicing an interrupt and the |
| other was executing in thread context, our assumption that each |
| spinning lock is acquired always on the same CPU priority level is |
| violated. |
| b2) The last likely scenario is that the deadlock happened between |
| two threads executing on the same CPU with IRQ's enabled. Again, |
| this means that we were working with incorrect code because it |
| contained wrong ordering of lock operations. |
| Since there is no possibility left, except for trivial errors, we |
| have shown that the deadlock contradicts with our assumptions and |
| therefore is not possible. |
| Q.E.D. |
| Notes on the proof: |
| ad a) Deadlock between two CPUs is independent on the preemption |
| model. If we have this kind of deadlock, we would have had |
| the same kind of deadlock on an ordinary SMP system with |
| kernel preemption disabled. |
| This preemption model makes UP behave more like SMP because |
| it introduces some SMP specific specialities. |
| ad b2) Notice that the scenario when thread A acquires lock X and |
| gets preempted in favor of thread B which is trying to |
| acquire lock X, doesn't deadlock the two threads. Of course, |
| B won't be allowed to get X until A releases it, but that |
| will certainly happen because B too will sooner or later be |
| preempted. This scenario emphasizes the efficiency issues, |
| though. |
