nvme-pci: implement the HMB entry number and size limitations

2017-09-11T16:29:40Z

Adds support for the new Host Memory Buffer Minimum Descriptor Entry Size and Host Memory Maximum Descriptors Entries field that were added in TP 4002 HMB Enhancements. These allow the controller to advertise limits for the usual number of segments in the host memory buffer, as well as a minimum usable per-segment size.

Merge branch 'for-4.14/block-postmerge' of git://git.kernel.dk/linux-block

Pull followup block layer updates from Jens Axboe: "I ended up splitting the main pull request for this series into two, mainly because of clashes between NVMe fixes that went into 4.13 after the for-4.14 branches were split off. This pull request is mostly NVMe, but not exclusively. In detail, it contains: - Two pull request for NVMe changes from Christoph. Nothing new on the feature front, basically just fixes all over the map for the core bits, transport, rdma, etc. - Series from Bart, cleaning up various bits in the BFQ scheduler. - Series of bcache fixes, which has been lingering for a release or two. Coly sent this in, but patches from various people in this area. - Set of patches for BFQ from Paolo himself, updating both documentation and fixing some corner cases in performance. - Series from Omar, attempting to now get the 4k loop support correct. Our confidence level is higher this time. - Series from Shaohua for loop as well, improving O_DIRECT performance and fixing a use-after-free" * 'for-4.14/block-postmerge' of git://git.kernel.dk/linux-block: (74 commits) bcache: initialize dirty stripes in flash_dev_run() loop: set physical block size to logical block size bcache: fix bch_hprint crash and improve output bcache: Update continue_at() documentation bcache: silence static checker warning bcache: fix for gc and write-back race bcache: increase the number of open buckets bcache: Correct return value for sysfs attach errors bcache: correct cache_dirty_target in __update_writeback_rate() bcache: gc does not work when triggering by manual command bcache: Don't reinvent the wheel but use existing llist API bcache: do not subtract sectors_to_gc for bypassed IO bcache: fix sequential large write IO bypass bcache: Fix leak of bdev reference block/loop: remove unused field block/loop: fix use after free bfq: Use icq_to_bic() consistently bfq: Suppress compiler warnings about comparisons bfq: Check kstrtoul() return value bfq: Declare local functions static ...
