    This cleans up kdump documentation a bit. Plus I do not think we want
    to mention Linux trademark in _every_ file in documentation....

  • ac984abe1   Add reset_devices to the recommended parameters ... Browse Code »

    This patch adds the "reset_devices" option (that's used only by one device
    driver for now) to the recommended list of command line parameters for kdump.

    Meaning (Documentation/kernel-parameters.txt):
    reset_devices [KNL] Force drivers to reset the underlying device
    during initialization.

    This patch adapts the Documentation/kdump/kdump.txt file to express the fact
    that the x86_64 kernel is now also relocatable. This makes i386 and x86_64
    now behave the same, simplifying the documentation.

    I've noticed that the boot options are not correct for in the documentation
    for kdump. The "init" keyword is not necessary, and causes a kernel panic
    when booting with an initrd on Fedora 5.

    o Kdump documentation update.
    - Update details for using relocatable kernel.
    - Start using kexec-tools-testing release as it is latest and old
    kexec-tools can't load relocatable bzImage file.
    - Also add kdump on ia64 specific details.

    In a testament to the utter simplicity and logic of the English
    language ;-), I found a single correct use - in kernel/panic.c - and
    10-15 incorrect ones.

    o Specify "irqpoll" command line option which loading second kernel. This
    helps in reducing driver initialization failures in second kernel due
    to shared interrupts.
    o Enabled LAPIC/IOAPIC support for UP kernels in second kernel. This reduces
    the chances of devices sharing the irq and hence reduces the chances of
    driver initialization failures in second kernel.
    o Build a UP capture kernel and disabled SMP support.

  • b089f4a68   [PATCH] kdump: Documentation for Kdump ... Browse Code »

    This patch contains the documentation for the kexec based crash dump tool.

    Quick kdump-howto
    ================================================================

    1) Download and build kexec-tools.

    2) Download and build the latest kexec/kdump (-mm) kernel patchset.
    Two kernels need to be built in order to get this feature working.

    A) First kernel:
    a) Enable "kexec system call" feature:
    CONFIG_KEXEC=y
    b) Physical load address (use default):
    CONFIG_PHYSICAL_START=0x100000
    c) Enable "sysfs file system support":
    CONFIG_SYSFS=y
    d) Boot into first kernel with the command line parameter "crashkernel=Y@X":
    For example: "crashkernel=64M@16M".

    B) Second kernel:
    a) Enable "kernel crash dumps" feature:
    CONFIG_CRASH_DUMP=y
    b) Physical load addreess, use same load address as X in "crashkernel"
    kernel parameter in d) above, e.g., 16 MB or 0x1000000.
    CONFIG_PHYSICAL_START=0x1000000
    c) Enable "/proc/vmcore support" (Optional, in Pseudo filesystems).
    CONFIG_PROC_VMCORE=y

    3) Boot into the first kernel.

    4) Load the second kernel to be booted using:

    kexec -p --crash-dump --args-linux --append="root=
    maxcpus=1 init 1"

    5) System reboots into the second kernel when a panic occurs. A module can be
    written to force the panic, for testing purposes.

    6) See Documentation/kdump.txt for how to read the first kernel's
    memory image and how to analyze it.
