  17   18  .Sh NAME
  18   19  .Nm nvme
  19   20  .Nd Intel NVMe compliant storage driver
  20   21  .Sh DESCRIPTION
  21   22  The
  22   23  .Nm
  23   24  driver uses the
  24   25  .Xr blkdev 7D
  25   26  framework to provide access to
  26      -.Tn Intel
       27 +Intel
  27   28  NVMe compliant solid-state storage devices.
  28   29  .Lp
  29   30  NVMe devices supporting multiple namespaces will present each
  30   31  namespace as its own
  31   32  .Xr blkdev 7D
  32   33  instance in the system.
  33   34  .
  34   35  .Sh CONFIGURATION
  35   36  The
  36   37  .Nm
  37   38  driver can be configured by defining properties in the
  38   39  .Pa nvme.conf
  39   40  file.
  40   41  The parameters are considered an unstable interface, subject to

  42   43  The following properties are currently supported:
  43   44  .Bl -tag -width Va
  44   45  .It Va strict-version
  45   46  This can be set to 0 to allow
  46   47  .Nm
  47   48  to attach to devices supporting newer version of the NVMe
  48   49  specification.
  49   50  The default value is 1, limiting
  50   51  .Nm
  51      -to work with devices up to specification version 1.2.
       52 +to work with devices that support major version 1.
  52   53  .It Va ignore-unknown-vendor-status
  53   54  This can be set to 1 to allow
  54   55  .Nm
  55   56  to continue operating even if it receives an unknown vendor command
  56   57  status.
  57   58  .It Va admin-queue-len
  58   59  This is the number of entries in the admin command queue.
  59   60  Legal values are between 16 and 4096, the default value is 256.
  60   61  .It Va io-queue-len
  61   62  This is the number of entries in each I/O command queue.
  62   63  Legal values are between 16 and 65536, the default value is 1024.
  63   64  .It Va async-event-limit
  64   65  This is the maximum number of asynchronous event requests issued by
  65   66  the driver.
  66   67  Asynchronous events are used to report error conditions.
  67   68  The driver will never use more asynchronous events than this value, or
  68   69  what the hardware supports if it is less, or 1/10th of the admin queue
  69   70  length if it is less.
  70   71  .It Va volatile-write-cache-enable
  71   72  This property can be set to 0 to disable the volatile write cache, if
  72   73  the hardware supports it.
  73   74  The default setting is 1, which enables the volatile write cache.
  74   75  .It Va min-phys-block-size
  75   76  This is the minimum physical block size that is reported to
  76   77  .Xr blkdev 7d .
  77   78  This value must be a power of 2 greater than or equal to 512.
  78   79  If the device reports a best block size larger than what is
  79   80  specified here the driver will ignore the value specified here.

  82   83  .Sh FILES
  83   84  .Bl -tag -compact -width Pa
  84   85  .It Pa /dev/dsk/cntnd0sn
  85   86  Block device minor nodes.
  86   87  .It Pa /dev/rdsk/cntnd0sn
  87   88  Raw block device minor nodes.
  88   89  .El
  89   90  .Lp
  90   91  In the device minor nodes, the following substitutions may occur:
  91   92  .Bl -tag -offset indent -width Va
  92   93  .It Va cn
  93   94  A controller number, typically one for each
  94   95  .Nm
  95   96  device found.
  96   97  Controller numbers are dynamically assigned by the system.
  97   98  .It Va tn
  98   99  The target number.
  99  100  This is the namespace EUI64 if available, or the namespace ID used by
 100  101  the hardware.
 101  102  Namespace ID 0 is reserved, hence target numbers start with 1.
 102  103  .It Va sn
 103  104  This is the
 104  105  .Em slice
 105  106  number, representing a subset of the disk.
