    Subject[PATCH 63/76] Update documentation for parameter *notrigger* in einj.txt
    Date
    From: Chen Gong <gong.chen@linux.intel.com>

    Add description of parameter notrigger in the einj.txt.
    One can utilize this new parameter to do some SRAR injection
    test. Pay attention, the operation is highly depended on the
    BIOS implementation. If no proper BIOS supports it, even if
    enabling this parameter, expected result will not happen.

    v2:
    Update the documentation suggested by Tony

    +- notrigger
    + The EINJ mechanism is a two step process. First inject the error, then
    + perform some actions to trigger it. Setting "notrigger" to 1 skips the

    BIOS versions based in the ACPI 4.0 specification have limited options
    to control where the errors are injected. Your BIOS may support an
    extension (enabled with the param_extension=1 module parameter, or
