286 * *
287 * Description: This register's value is a bit vector that guards *
288 * access to local registers within the II as well as to external *
289 * Crosstalk widgets. Each bit in the register corresponds to a *
290 * particular region in the system; a region consists of one, two or *
291 * four nodes (depending on the value of the REGION_SIZE field in the *
292 * LB_REV_ID register, which is documented in Section 8.3.1.1). The *
293 * protection provided by this register applies to PIO read *
294 * operations as well as PIO write operations. The II will perform a *
295 * PIO read or write request only if the bit for the requestor's *
296 * region is set; otherwise, the II will not perform the requested *
297 * operation and will return an error response. When a PIO read or *
298 * write request targets an external Crosstalk widget, then not only *
299 * must the bit for the requestor's region be set in the ILAPR, but *
300 * also the target widget's bit in the IOWA register must be set in *
301 * order for the II to perform the requested operation; otherwise, *
302 * the II will return an error response. Hence, the protection *
303 * provided by the IOWA register supplements the protection provided *
304 * by the ILAPR for requests that target external Crosstalk widgets. *
305 * This register itself can be accessed only by the nodes whose *
306 * region ID bits are enabled in this same register. It can also be *
307 * accessed through the IAlias space by the local processors. *
308 * The reset value of this register allows access by all nodes. *

797 * For the N-mode (256 nodes, 4 GBytes/node), SysAD[30:28] (Big *
798 * Window number) are used to select one of these 7 registers. The *
799 * Widget number field is then derived from the W_NUM field for *
800 * synthesizing a Crosstalk packet. The 5 bits of OFFSET are *
801 * concatenated with SysAD[27:0] to form Crosstalk[33:0]. The IOSP *
802 * field is used as Crosstalk[47], and remainder of the Crosstalk *
803 * address bits (Crosstalk[46:34]) are always zero. While the maximum *
804 * Crosstalk space addressable by the SHub is thus the lower *
805 * 8-GBytes per widget (N-mode), only <SUP >7</SUP>/<SUB >32nds</SUB> *
806 * of this space can be accessed. *

1273 * *
1274 * Description: This register specifies the timeout value to use for *
1275 * monitoring Crosstalk tail flits coming into the Shub in the *
1276 * TAIL_TO field. An internal counter associated with this register *
1277 * is incremented every 128 II internal clocks (7 bits). The counter *
1278 * starts counting anytime a header micropacket is received and stops *
1279 * counting (and resets to zero) any time a micropacket with a Tail *
1280 * bit is received. Once the counter reaches the threshold value *
1281 * programmed in this register, it generates an interrupt to the *
1282 * processor that is programmed into the IIDSR. The counter saturates *
1283 * (does not roll over) at its maximum value, so it cannot cause *
1284 * another interrupt until after it is cleared. *
1285 * The register also contains the Read Response Timeout values. The *
1286 * Prescalar is 23 bits, and counts II clocks. An internal counter *
1287 * increments on every II clock and when it reaches the value in the *
1288 * Prescalar field, all IPRTE registers with their valid bits set *
1289 * have their Read Response timers bumped. Whenever any of them match *
1290 * the value in the RRSP_TO field, a Read Response Timeout has *
1291 * occurred, and error handling occurs as described in the Error *
1292 * Handling section of this document. *

1380 * not the same as the widget recorded in the IPRTE register *
1381 * referenced by the TNUM. If this condition is true, and if the *
1382 * IXSS[VALID] bit is clear, then the header of the spurious read *
1383 * response is capture in IXSM and IXSS, and IXSS[VALID] is set. The *
1384 * errant header is thereby captured, and no further spurious read *
1385 * respones are captured until IXSS[VALID] is cleared by setting the *
1386 * appropriate bit in IECLR.Everytime a spurious read response is *
1387 * detected, the SPUR_RD bit of the PRB corresponding to the incoming *
1388 * message's SIDN field is set. This always happens, regarless of *
1389 * whether a header is captured. The programmer should check *
1390 * IXSM[SIDN] to determine which widget sent the spurious response, *
1391 * because there may be more than one SPUR_RD bit set in the PRB *
1392 * registers. The widget indicated by IXSM[SIDN] was the first *
1393 * spurious read response to be received since the last time *

3156 * Many of the fields in CRB are status bits used by hardware

3160 * It's OK to read the CRB registers and try to make sense out of the
3161 * fields in CRB.

3163 * Updating CRB requires all activities in Hub IIO to be quiesced.
3164 * otherwise, a write to CRB could corrupt other CRB entries.
3165 * CRBs are here only as a back door peek to shub IIO's status.
3166 * Quiescing implies no dmas no PIOs
3167 * either directly from the cpu or from sn0net.
3168 * this is not something that can be done easily. So, AVOID updating
