- * [ NOTE 1 ]:
- * Data cache (L1 D$ or SL$) entire invalidate operation or data cache disable
- * operation may result in unexpected behavior and data loss even if we flush
- * data cache right before invalidation. That may happens if we store any context
- * on stack (like we store BLINK register on stack before function call).
- * BLINK register is the register where return address is automatically saved
- * when we do function call with instructions like 'bl'.
- *
- * There is the real example:
- * We may hang in the next code as we store any BLINK register on stack in
- * invalidate_dcache_all() function.
- *
- * void flush_dcache_all() {
- *     __dc_entire_op(OP_FLUSH);
- *     // Other code //
- * }
- *
- * void invalidate_dcache_all() {
- *     __dc_entire_op(OP_INV);
- *     // Other code //
- * }
- *
- * void foo(void) {
- *     flush_dcache_all();
- *     invalidate_dcache_all();
- * }
- *
- * Now let's see what really happens during that code execution:
- *
- * foo()
- *   |->> call flush_dcache_all
- *     [return address is saved to BLINK register]
- *     [push BLINK] (save to stack)              ![point 1]
- *     |->> call __dc_entire_op(OP_FLUSH)
- *         [return address is saved to BLINK register]
- *         [flush L1 D$]
- *         return [jump to BLINK]
- *     <<------
- *     [other flush_dcache_all code]
- *     [pop BLINK] (get from stack)
- *     return [jump to BLINK]
- *   <<------
- *   |->> call invalidate_dcache_all
- *     [return address is saved to BLINK register]
- *     [push BLINK] (save to stack)               ![point 2]
- *     |->> call __dc_entire_op(OP_FLUSH)
- *         [return address is saved to BLINK register]
- *         [invalidate L1 D$]                 ![point 3]
- *         // Oops!!!
- *         // We lose return address from invalidate_dcache_all function:
- *         // we save it to stack and invalidate L1 D$ after that!
- *         return [jump to BLINK]
- *     <<------
- *     [other invalidate_dcache_all code]
- *     [pop BLINK] (get from stack)
- *     // we don't have this data in L1 dcache as we invalidated it in [point 3]
- *     // so we get it from next memory level (for example DDR memory)
- *     // but in the memory we have value which we save in [point 1], which
- *     // is return address from flush_dcache_all function (instead of
- *     // address from current invalidate_dcache_all function which we
- *     // saved in [point 2] !)
- *     return [jump to BLINK]
- *   <<------
- *   // As BLINK points to invalidate_dcache_all, we call it again and
- *   // loop forever.
- *
- * Fortunately we may fix that by using flush & invalidation of D$ with a single
- * one instruction (instead of flush and invalidation instructions pair) and
- * enabling force function inline with '__attribute__((always_inline))' gcc
- * attribute to avoid any function call (and BLINK store) between cache flush
- * and disable.
- *
- *
- * [ NOTE 2 ]:
- * As of today we only support the following cache configurations on ARC.
- * Other configurations may exist in HW (for example, since version 3.0 HS
- * supports SL$ (L2 system level cache) disable) but we don't support it in SW.
