  • 5ba762c9b   powerpc/rtas: Fix watchdog driver temperature read functionality ... Browse Code »

    Using the RTAS watchdog driver to read out the temperature crashes
    on a PXCAB:

    Unable to handle kernel paging request for data at address 0xfe347b50
    Faulting instruction address: 0xc00000000001af64
    Oops: Kernel access of bad area, sig: 11 [#1]

    The wrong usage of "(void *)__pa(&temperature)" in rtas_call() is
    removed by using the function rtas_get_sensor() which does the
    right thing.

    The buffer passed to the ibm,get-system-parameter RTAS call must be
    in the RMA. To ensure we pass an address in the RMA use rtas_data_buf
    for the actual RTAS call and then copy the result to value. We can't
    just make it static because this can be compiled in as a module.

    Also add the WDRTAS_SP_SPI_LEN so we don't litter '4' throughout the
    function.
