163 *
164 * The ioctl()s which are implemented (along with relevant details)
165 * are:
166 *
167 * ICARSAMODEXPO
168 * Perform an RSA operation using a Modulus-Exponent pair
169 * This takes an ica_rsa_modexpo struct as its arg.
170 *
171 * NOTE: please refer to the comments preceding this structure
172 * for the implementation details for the contents of the
173 * block
174 *
175 * ICARSACRT
176 * Perform an RSA operation using a Chinese-Remainder Theorem key
177 * This takes an ica_rsa_modexpo_crt struct as its arg.
178 *
179 * NOTE: please refer to the comments preceding this structure
180 * for the implementation details for the contents of the
181 * block
182 *
183 * ZSECSENDCPRB
184 * Send an arbitrary CPRB to a crypto card.
185 *
186 * Z90STAT_STATUS_MASK
187 * Return an 64 element array of unsigned chars for the status of
188 * all devices.
189 * 0x01: PCICA
190 * 0x02: PCICC
191 * 0x03: PCIXCC_MCL2
192 * 0x04: PCIXCC_MCL3
193 * 0x05: CEX2C
194 * 0x06: CEX2A
195 * 0x0d: device is disabled via the proc filesystem
196 *
197 * Z90STAT_QDEPTH_MASK
198 * Return an 64 element array of unsigned chars for the queue
199 * depth of all devices.
200 *
201 * Z90STAT_PERDEV_REQCNT
202 * Return an 64 element array of unsigned integers for the number
203 * of successfully completed requests per device since the device
204 * was detected and made available.
205 *
206 * Z90STAT_REQUESTQ_COUNT
207 * Return an integer count of the number of entries waiting to be
208 * sent to a device.
209 *
210 * Z90STAT_PENDINGQ_COUNT
211 * Return an integer count of the number of entries sent to all
212 * devices awaiting the reply.
213 *
214 * Z90STAT_TOTALOPEN_COUNT
215 * Return an integer count of the number of open file handles.
216 *
217 * Z90STAT_DOMAIN_INDEX
218 * Return the integer value of the Cryptographic Domain.
219 *
220 * The following ioctls are deprecated and should be no longer used:
221 *
222 * Z90STAT_TOTALCOUNT
223 * Return an integer count of all device types together.
224 *
225 * Z90STAT_PCICACOUNT
226 * Return an integer count of all PCICAs.
227 *
228 * Z90STAT_PCICCCOUNT
229 * Return an integer count of all PCICCs.
230 *
231 * Z90STAT_PCIXCCMCL2COUNT
232 * Return an integer count of all MCL2 PCIXCCs.
233 *
234 * Z90STAT_PCIXCCMCL3COUNT
235 * Return an integer count of all MCL3 PCIXCCs.
236 *
237 * Z90STAT_CEX2CCOUNT
238 * Return an integer count of all CEX2Cs.
239 *
240 * Z90STAT_CEX2ACOUNT
241 * Return an integer count of all CEX2As.
242 *
243 * ICAZ90STATUS
244 * Return some device driver status in a ica_z90_status struct
245 * This takes an ica_z90_status struct as its arg.
246 *
247 * Z90STAT_PCIXCCCOUNT
248 * Return an integer count of all PCIXCCs (MCL2 + MCL3).
249 * This is DEPRECATED now that MCL3 PCIXCCs are treated differently from
250 * MCL2 PCIXCCs.
