20

21 
 * revisions. Certain macros are defined for silicon-revision none - this
22 
 * is to ensure behaviour is unchanged from libraries supplied with
23 
 * earlier tools versions, where a small number of anomaly workarounds
24 
 * were applied in all library flavours. __FORCE_LEGACY_WORKAROUNDS__
25 
 * is defined in this case.
26 
 *
27 
 * This file defines macros for a subset of all anomalies that may impact
28

/* 05-00-0261 - "DCPLB_FAULT_ADDR MMR may be corrupted".
372 
 * The DCPLB_FAULT_ADDR MMR may contain the fault address of a
373 
 * aborted memory access which generated both a protection exception
374 
 * and a stall.
375 
 *
376 
 * We work around this by initially ignoring a DCPLB miss exception
377 
 * on the assumption that the faulting address might be invalid.
378 
 * We return without servicing. The exception will be raised
379 
 * again when the faulting instruction is re-executed. The fault
380 
 * address is correct this time round so the miss exception can
381 
 * be serviced as normal. The only complication is we have to
382 
 * ensure that we are about to service the same miss rather than
383 
 * a miss raised within a higher-priority interrupt handler, where
384 
 * the fault address could again be invalid. We therefore record
385 
 * the last seen RETX and only service an exception when RETX and
386 
 * the last seen RETX are equal.

556

557 
 *
558 
 * This issue occurs only when the accesses are performed by core B of a BF561.
559 
 *
560 
 * When a write to internal L2 memory follows a speculative read from internal
561 
 * L2 memory, the L2 write may be lost or corrupted. For this anomaly to occur,
562 
 * the speculative read must be caused by a read in the shadow of a branch. The
563 
 * accesses do not have to be consecutive accesses. In other words, the problem
564 
 * can occur even if there are multiple instructions between the speculative
565 
 * read and the write, as shown in the following example:
566 
 *
567 
 *   R1 = 1; R2 = 1;
568 
 *   CC = R1 == R2;
569 
 *   IF CC JUMP X;  // Always true...
570 
 *   R0 = [P0];     // If any of these three loads accesses L2 memory from Core
571 
 *   R1 = [P1];     // B, speculative execution in the pipeline causes the
572 
 *   R2 = [P2];     // anomaly trigger condition.
573 
 *   X:
574 
 *   ...            // Any number of instructions...
575 
 *   [P0] = R0;  // This write can be corrupted or lost.
576 
 *
577 
 * The issue does not occur if the speculative read access is caused by an
578 
 * interrupt or exception.
579 
 *
580 
 * The workaround required depends upon the conditional branch instruction.
581 
 * If the evaluated condition is true and the branch is predicted, then the
582 
 * workaround is to ensure that the target instruction is not be a load
583 
 * instruction, for example:
584 
 *
585 
 *   IF CC JUMP X (BP);
586 
 *   ...
587 
 *   X: <load that might be from L2 memory>
588 
 *
589 
 * If the evaluated condition is false and the branch is not predicted, then
590 
 * the workaround is to make sure that none of the three instructions that
591 
 * are executed after the conditional JUMP are load instructions, for example:
592 
 *
593 
 *   IF CC JUMP ...;
594 
 *   <load that might be from L2 memory>
595 
 *   <load that might be from L2 memory>
