[PATCH] libata: Add new med_power_with_dipm link_power_management_policy setting

As described by Matthew Garret quite a while back: https://mjg59.dreamwidth.org/34868.html Intel CPUs starting with the Haswell generation need SATA links to power down for the "package" part of the CPU to reach low power-states like PC7 / P8 which bring a significant power-saving with them. The

[PATCH 4/5] lightnvm: pblk: do not use a mempool for line bitmaps

pblk holds two sector bitmaps: one to keep track of the mapped sectors while the line is active and another one to keep track of the invalid sectors. The latter is kept during the whole live of the line, until it is recycled. Since we cannot guarantee forward progress for the mempool in this case,

Hi All, As described by Matthew Garret quite a while back: https://mjg59.dreamwidth.org/34868.html On Intel CPUs starting with the Haswell generation SATA link power management can save a significant amount of power. Previous attempts to try and enable SATA LPM by default have gotten stuck on om

[PATCH 0/5] lightnvm: pblk: audit mempool usage

As suggested by Jens [1], I audited all mempools on pblk. This patche series (i) fixes bad mempool allocations that did not guarantee forward progress and downsizes the sizes of some overused mempools, (ii) removes unnecessary checks, and (iii) eliminates some mempools that where introduced in ear
