This patch moves the 1.2 and 2.0 block/chunk metadata retrieval to core. Hi Javier, I did not end up using your patch. I had misunderstood what was implemented. Instead I implemented the detection of the each chunk by first sensing the first page, then the last page, and if the chunk is sensed as open, a per page scan will be executed to update the write pointer appropriately. Note that one needs a real drive to test the implementation. The 1.2 qemu implementation is lacking. I did update it a bit, such that it defaults to all blocks being free. It can be picked up in the ocssd qemu repository. Changes since v1: - Add sensing of chunks wrt to free/open/closed - Add update of write pointer if chunk state is open Matias Bjørling (1): lightnvm: move bad block and chunk state logic to core drivers/lightnvm/core.c | 310 +++++++++++++++++++++++++++++++++++-------- drivers/lightnvm/pblk-core.c | 6 +- drivers/lightnvm/pblk-init.c | 116 +--------------- drivers/lightnvm/pblk.h | 2 +- drivers/nvme/host/lightnvm.c | 4 +- include/linux/lightnvm.h | 15 +-- 6 files changed, 266 insertions(+), 187 deletions(-) -- 2.11.0
