1 INTRO(9S) Data Structures for Drivers INTRO(9S) 2 3 4 5 NAME 6 Intro, intro - introduction to kernel data structures and properties 7 8 DESCRIPTION 9 Section 9P describes kernel properties used by device drivers. Section 10 9S describes the data structures used by drivers to share information 11 between the driver and the kernel. See Intro(9E) for an overview of 12 device driver interfaces. 13 14 15 In Section 9S, reference pages contain the following headings: 16 17 o NAME summarizes the purpose of the structure or property. 18 19 o SYNOPSIS lists the include file that defines the structure 20 or property. 21 22 o INTERFACE LEVEL describes any architecture dependencies. 23 24 o DESCRIPTION provides general information about the structure 25 or property. 26 27 o STRUCTURE MEMBERS lists all accessible structure members 28 (for Section 9S). 29 30 o SEE ALSO gives sources for further information. 31 32 33 Of the preceding headings, Section 9P reference pages contain the NAME, 34 DESCRIPTION, and SEE ALSO fields. 35 36 37 Every driver MUST include <sys/ddi.h> and <sys/sunddi.h>, in that 38 order, and as final entries. 39 40 41 The following table summarizes the STREAMS structures described in 42 Section 9S. 43 44 45 46 47 +------------+-------------+ 48 | Structure | Type | 49 +------------+-------------+ 50 |copyreq | DDI/DKI | 51 +------------+-------------+ 52 |copyresp | DDI/DKI | 53 +------------+-------------+ 54 |datab | DDI/DKI | 55 +------------+-------------+ 56 |fmodsw | Solaris DDI | 57 +------------+-------------+ 58 |free_rtn | DDI/DKI | 59 +------------+-------------+ 60 |iocblk | DDI/DKI | 61 +------------+-------------+ 62 |linkblk | DDI/DKI | 63 +------------+-------------+ 64 |module_info | DDI/DKI | 65 +------------+-------------+ 66 |msgb | DDI/DKI | 67 +------------+-------------+ 68 |qband | DDI/DKI | 69 +------------+-------------+ 70 |qinit | DDI/DKI | 71 +------------+-------------+ 72 |queclass | Solaris DDI | 73 +------------+-------------+ 74 |queue | DDI/DKI | 75 +------------+-------------+ 76 |streamtab | DDI/DKI | 77 +------------+-------------+ 78 |stroptions | DDI/DKI | 79 +------------+-------------+ 80 81 82 The following table summarizes structures that are not specific to 83 STREAMS I/O. 84 85 86 87 88 +--------------------+-----------------+ 89 | Structure | Type | 90 +--------------------+-----------------+ 91 |aio_req | Solaris DDI | 92 +--------------------+-----------------+ 93 |buf | DDI/DKI | 94 +--------------------+-----------------+ 95 |cb_ops | Solaris DDI | 96 +--------------------+-----------------+ 97 |ddi_device_acc_attr | Solaris DDI | 98 +--------------------+-----------------+ 99 |ddi_dma_attr | Solaris DDI | 100 +--------------------+-----------------+ 101 |ddi_dma_cookie | Solaris DDI | 102 +--------------------+-----------------+ 103 |ddi_dmae_req | Solaris x86 DDI | 104 +--------------------+-----------------+ 105 |ddi_idevice_cookie | Solaris DDI | 106 +--------------------+-----------------+ 107 |ddi_mapdev_ctl | Solaris DDI | 108 +--------------------+-----------------+ 109 |devmap_callback_ctl | Solaris DDI | 110 +--------------------+-----------------+ 111 |dev_ops | Solaris DDI | 112 +--------------------+-----------------+ 113 |iovec | DDI/DKI | 114 +--------------------+-----------------+ 115 |kstat | Solaris DDI | 116 +--------------------+-----------------+ 117 |kstat_intr | Solaris DDI | 118 +--------------------+-----------------+ 119 |kstat_io | Solaris DDI | 120 +--------------------+-----------------+ 121 |kstat_named | Solaris DDI | 122 +--------------------+-----------------+ 123 |map | DDI/DKI | 124 +--------------------+-----------------+ 125 |modldrv | Solaris DDI | 126 +--------------------+-----------------+ 127 |modlinkage | Solaris DDI | 128 +--------------------+-----------------+ 129 |modlstrmod | Solaris DDI | 130 +--------------------+-----------------+ 131 |scsi_address | Solaris DDI | 132 +--------------------+-----------------+ 133 |scsi_arq_status | Solaris DDI | 134 +--------------------+-----------------+ 135 |scsi_device | Solaris DDI | 136 +--------------------+-----------------+ 137 |scsi_extended_sense | Solaris DDI | 138 +--------------------+-----------------+ 139 |scsi_hba_tran | Solaris DDI | 140 +--------------------+-----------------+ 141 |scsi_inquiry | Solaris DDI | 142 +--------------------+-----------------+ 143 |scsi_pkt | Solaris DDI | 144 +--------------------+-----------------+ 145 |scsi_status | Solaris DDI | 146 +--------------------+-----------------+ 147 |uio | DDI/DKI | 148 +--------------------+-----------------+ 149 150 SEE ALSO 151 Intro(9E) 152 153 NOTES 154 Do not declare arrays of structures as the size of the structures can 155 change between releases. Rely only on the structure members listed in 156 this chapter and not on unlisted members or the position of a member in 157 a structure. 158 159 160 161 May 24, 2014 INTRO(9S) --- EOF ---
