[PATCH v2 0/3] add columns for zoned parameters

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Several parameters for zoned devices are missing from lsblk's columns. This
series introduces them as following.

 Column Name   Description             Sysfs path
 ------------------------------------------------------------------
 ZONE-SZ       zone size               queue/chunk_sectors
 ZONE-GRAN     zone write granularity  queue/zone_write_granularity
 ZONE-APP      zone append max bytes   queue/zone_append_max_bytes
 ZONE-NR       number of zones         queue/nr_zones
 ZONE-OMAX     max open zones          queue/max_open_zones
 ZONE-AMAX     max active zones        queue/max_active_zones

These columns are also added to the "-z" output.

Sample output:

$ lsblk -z -i

$ lsblk --help|grep -i zone

        ZONED  zone model
      ZONE-SZ  zone size
    ZONE-GRAN  zone write granularity
     ZONE-APP  zone append max bytes
      ZONE-NR  number of zones
    ZONE-OMAX  max open zones
    ZONE-AMAX  max active zones

  lsblk: factor out function to read sysfs param as bytes
  lsblk: add columns of zoned parameters
  lsblk: add zoned columns to "lsblk -z"
