4 This text file will detail the queue files that are located in the sysfs tree
7 These files are the ones found in the /sys/block/xxx/queue/ directory.
9 Files denoted with a RO postfix are readonly and the RW postfix means
14 This file allows to turn off the disk entropy contribution. Default
19 This shows the size of internal allocation of the device in bytes, if
20 reported by the device. A value of '0' means device does not support
21 the discard functionality.
26 the number of bytes that can be trimmed or unmapped in a single operation.
27 The discard_max_bytes parameter is set by the device driver to the maximum
29 requests issued to the device must not exceed this limit. A discard_max_bytes
30 value of 0 means that the device does not support discard functionality.
34 When read, this file will show if the discarded block are zeroed by the
35 device or not. If its value is '1' the blocks are zeroed otherwise not.
39 This is the hardware sector size of the device, in bytes.
43 This file is used to control (on/off) the iostats accounting of the
48 This is the logcal block size of the device, in bytes.
52 This is the maximum number of kilobytes supported in a single data transfer.
56 When read, this file shows the max limit of integrity segments as
61 This is the maximum number of kilobytes that the block layer will allow
62 for a filesystem request. Must be smaller than or equal to the maximum
63 size allowed by the hardware.
67 Maximum number of segments of the device.
71 Maximum segment size of the device.
75 This is the smallest preferred IO size reported by the device.
79 This enables the user to disable the lookup logic involved with IO
80 merging requests in the block layer. By default (0) all merges are
87 This controls how many requests may be allocated in the block layer for
88 read or write requests. Note that the total allocated number may be twice
89 this amount, since it applies only to reads or writes (not the accumulated
101 This is the optimal IO size reported by the device.
105 This is the physical block size of device, in bytes.
114 This file is used to stat if the device is of rotational type or
119 If this option is '1', the block layer will migrate request completions to the
120 cpu "group" that originally submitted the request. For some workloads this
124 processing setting this option to '2' forces the completion to run on the
125 requesting cpu (bypassing the "group" aggregation logic).
129 When read, this file will display the current and available IO schedulers
134 module, if it isn't already present in the system.
