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