83 * Interface notes:
84 *
85 * The ioctl()s which are implemented (along with relevant details)
86 * are:
87 *
88 * ICARSAMODEXPO
89 * Perform an RSA operation using a Modulus-Exponent pair
90 * This takes an ica_rsa_modexpo struct as its arg.
91 *
92 * NOTE: please refer to the comments preceding this structure
93 * for the implementation details for the contents of the
94 * block
95 *
96 * ICARSACRT
97 * Perform an RSA operation using a Chinese-Remainder Theorem key
98 * This takes an ica_rsa_modexpo_crt struct as its arg.
99 *
100 * NOTE: please refer to the comments preceding this structure
101 * for the implementation details for the contents of the
102 * block
103 *
104 * Z90STAT_TOTALCOUNT
105 * Return an integer count of all device types together.
106 *
107 * Z90STAT_PCICACOUNT
108 * Return an integer count of all PCICAs.
109 *
110 * Z90STAT_PCICCCOUNT
111 * Return an integer count of all PCICCs.
112 *
113 * Z90STAT_PCIXCCMCL2COUNT
114 * Return an integer count of all MCL2 PCIXCCs.
115 *
116 * Z90STAT_PCIXCCMCL3COUNT
117 * Return an integer count of all MCL3 PCIXCCs.
118 *
119 * Z90STAT_CEX2CCOUNT
120 * Return an integer count of all CEX2Cs.
121 *
122 * Z90STAT_CEX2ACOUNT
123 * Return an integer count of all CEX2As.
124 *
125 * Z90STAT_REQUESTQ_COUNT
126 * Return an integer count of the number of entries waiting to be
127 * sent to a device.
128 *
129 * Z90STAT_PENDINGQ_COUNT
130 * Return an integer count of the number of entries sent to a
131 * device awaiting the reply.
132 *
133 * Z90STAT_TOTALOPEN_COUNT
134 * Return an integer count of the number of open file handles.
135 *
136 * Z90STAT_DOMAIN_INDEX
137 * Return the integer value of the Cryptographic Domain.
138 *
139 * Z90STAT_STATUS_MASK
140 * Return an 64 element array of unsigned chars for the status of
141 * all devices.
142 * 0x01: PCICA
143 * 0x02: PCICC
144 * 0x03: PCIXCC_MCL2
145 * 0x04: PCIXCC_MCL3
146 * 0x05: CEX2C
147 * 0x06: CEX2A
148 * 0x0d: device is disabled via the proc filesystem
149 *
150 * Z90STAT_QDEPTH_MASK
151 * Return an 64 element array of unsigned chars for the queue
152 * depth of all devices.
153 *
154 * Z90STAT_PERDEV_REQCNT
155 * Return an 64 element array of unsigned integers for the number
156 * of successfully completed requests per device since the device
157 * was detected and made available.
158 *
159 * ICAZ90STATUS (deprecated)
160 * Return some device driver status in a ica_z90_status struct
161 * This takes an ica_z90_status struct as its arg.
162 *
163 * NOTE: this ioctl() is deprecated, and has been replaced with
164 * single ioctl()s for each type of status being requested
165 *
166 * Z90STAT_PCIXCCCOUNT (deprecated)
167 * Return an integer count of all PCIXCCs (MCL2 + MCL3).
168 * This is DEPRECATED now that MCL3 PCIXCCs are treated differently from
169 * MCL2 PCIXCCs.
170 *
171 * Z90QUIESCE (not recommended)
172 * Quiesce the driver. This is intended to stop all new
173 * requests from being processed. Its use is NOT recommended,
174 * except in circumstances where there is no other way to stop
175 * callers from accessing the driver. Its original use was to
176 * allow the driver to be "drained" of work in preparation for
177 * a system shutdown.
178 *
179 * NOTE: once issued, this ban on new work cannot be undone
180 * except by unloading and reloading the driver.
