Indexed-count memory management allows addition and removal of contiguous lmb blocks with a single command. When compared to the series of calls previously required to manage contiguous blocks, indexed-count decreases command frequency and reduces risk of buffer overflow. Changes in v2: -------------- -[PATCH 1/2]: -remove potential memory leak when parsing command -use u32s drc_index and count instead of u32 ic[] in dlpar_memory -[PATCH 2/2]: -use u32s drc_index and count instead of u32 ic[] in dlpar_memory Changes in v3: -------------- -[PATCH 1/2]: -add logic to handle invalid drc_index input -update indexed-count trigger to follow naming convention -update dlpar_memory to follow kernel if-else style -[PATCH 2/2]: -add logic to handle invalid drc_index input Changes in v4: -------------- -[PATCH 1/2]: -add logic to handle kstrdup failure -add logic to handle invalid command format -Sahil Mehta --- include/asm/rtas.h | 2 platforms/pseries/dlpar.c | 48 ++++++++ platforms/pseries/hotplug-memory.c | 200 +++++++++++++++++++++++++++++++++++-- 3 files changed, 237 insertions(+), 13 deletions(-)
