| H A D | rtas-fadump.h | diff 78d5cc15fb7d1b2683f0baf418a9a870c02319fb Thu May 09 13:57:53 CEST 2024 Hari Bathini <hbathini@linux.ibm.com> powerpc/pseries/fadump: add support for multiple boot memory regions
Currently, fadump on pseries assumes a single boot memory region even
though f/w supports more than one boot memory region. Add support for
more boot memory regions to make the implementation flexible for any
enhancements that introduce other region types. For this, rtas memory
structure for fadump is updated to have multiple boot memory regions
instead of just one. Additionally, methods responsible for creating
the fadump memory structure during both the first and second kernel
boot have been modified to take these multiple boot memory regions
into account. Also, a new callback has been added to the fadump_ops
structure to get the maximum boot memory regions supported by the
platform.
