Hi, I am trying to understand remapping functionality and fmr_pool.c. Looking back at old thread: http://lists.openfabrics.org/pipermail/general/2006-February/017198.html
Can you please confirm whether my understanding is correct or not. 1. max_map_per_fmr indicates that - different memory pages can be remapped (again) without invoking unmap_fmr(). Basically previous mapping is over-written on every map_phys_fmr() call with new mapping without doing unmapping. 2. adapter indicates above limit - how many times old mapping can be overwritten (remapped) before invoking unmap_fmr(). 3. Remapping allows faster operation compare to map(), unmap() sequence, due to which unmap_fmr() is mostly done in worker threads in SDP, RDS etc consumers. Is above understanding correct?
