  • As discussed a few times on this list: A triple fault causes a system
    reset on x86, and some guests make use of this (e.g. 386BSD). To keep
    the chance of tracing unexpected resets, log them if CPU_LOG_RESET is

    Subject: Re: Slirp license
    
    Thanks for contacting me, Richard.  I'm glad you were able to find
    Dan, as I've been "keeping the light on" for Slirp.  I have no use for
    it now, and I have little time for it (now holding onto Keenspot's
    Comic Genesis and having a regular US state government position). If
    Dan would like to return to the project, I'd love to give it back to
    him.
    
    As for copyright, I don't own all of it.  Dan does, so I will defer to
    him.  Any of my patches I will gladly license to the 3-part BSD
    license.  My interest in re-licensing was because we didn't have ready
    info to contact Dan.  If Dan would like to port Slirp back out of
    QEMU, a lot of us 64-bit users would be grateful.
    
    Feel free to share this email address with Dan.  I will be glad to
    effect a transfer of the project to him and Mr. Bellard of the QEMU
    project.

  • The current codebase ignores MTRR (Memory Type Range Register)
    configuration writes and reads because Qemu does not implement caching.
    All BIOS/firmware in know of for x86 do implement a mode called
    Cache-as-RAM (CAR) which locks down the CPU cache lines and uses the CPU
    cache like RAM before RAM is enabled. Qemu assumes RAM is accessible
    from the start, but it would be nice to be able to run real
    BIOS/firmware in Qemu. For that, we need CAR support and for CAR support
    we have to support MTRRs.
    
    This patch is a first step in that direction. MTRRs are MSRs supported
    by all recent x86 CPUs, even old i586. Besides influencing cache, the
    MTRRs can be written and read back, so discarding MTRR writes violates
    the expectations of existing code out there.
    
    An added benefit of this patch is that it fixes the following Linux
    kernel error message present in recent kernels (provided the BIOS has
    the recent MTRR patches applied):
     ------------[ cut here ]------------

  • this patch fixes a bug and improves the generic pixel conversion
    function in vnc.c.
    The bug is that when a new vnc client connects we need to reset the flag
    has_WMVi but currently we don't.
    The generic pixel conversion function is vnc_convert_pixel and currently
    is not very efficient since uses the division and multiplication
    operators.
    To make it more efficient I changed to use bit shift operators instead.

  • A subsystem vendor ID of zero isn't allowed, so we use our
    default ID.
    
    Gerd points out that although the PCI subsystem vendor ID is
    treated by the guest as the virtio vendor ID:
    
       /* we use the subsystem vendor/device id as the virtio vendor/device
        * id.  this allows us to use the same PCI vendor/device id for all
        * virtio devices and to identify the particular virtio driver by
        * the subsytem ids */
        vp_dev->vdev.id.vendor = pci_dev->subsystem_vendor;
        vp_dev->vdev.id.device = pci_dev->subsystem_device;
    
    it looks like only the device ID is used right now:
    
       # grep virtio modules.alias
       alias virtio:d00000001v* virtio_net
       alias virtio:d00000002v* virtio_blk
       alias virtio:d00000003v* virtio_console
       alias virtio:d00000004v* virtio-rng
       alias virtio:d00000005v* virtio_balloon
       alias pci:v00001AF4d*sv*sd*bc*sc*i* virtio_pci
       alias virtio:d00000009v* 9pnet_virtio
    
    so setting the subsystem vendor id to something != zero shouldn't cause
    trouble.
