/* The macros in this file implement an exponential backoff facility
|
||||
* for atomic operations.
|
||||
*
|
||||
* When multiple threads compete on an atomic operation, it is
|
||||
* possible for one thread to be continually denied a successful
|
||||
* completion of the compare-and-swap instruction. Heavily
|
||||
* threaded cpu implementations like Niagara can compound this
|
||||
* problem even further.
|
||||
*
|
||||
* When an atomic operation fails and needs to be retried, we spin a
|
||||
* certain number of times. At each subsequent failure of the same
|
||||
* operation we double the spin count, realizing an exponential
|
||||
* backoff.
|
||||
*
|
||||
* When we spin, we try to use an operation that will cause the
|
||||
* current cpu strand to block, and therefore make the core fully
|
||||
* available to any other other runnable strands. There are two
|
||||
* options, based upon cpu capabilities.
|
||||
*
|
||||
* On all cpus prior to SPARC-T4 we do three dummy reads of the
|
||||
* condition code register. Each read blocks the strand for something
|
||||
* between 40 and 50 cpu cycles.
|
||||
*
|
||||
* For SPARC-T4 and later we have a special "pause" instruction
|
||||
* available. This is implemented using writes to register %asr27.
|
||||
* The cpu will block the number of cycles written into the register,
|
||||
* unless a disrupting trap happens first. SPARC-T4 specifically
|
||||
* implements pause with a granularity of 8 cycles. Each strand has
|
||||
* an internal pause counter which decrements every 8 cycles. So the
|
||||
* chip shifts the %asr27 value down by 3 bits, and writes the result
|
||||
* into the pause counter. If a value smaller than 8 is written, the
|
||||
* chip blocks for 1 cycle.
|
||||
*
|
||||
* To achieve the same amount of backoff as the three %ccr reads give
|
||||
* on earlier chips, we shift the backoff value up by 7 bits. (Three
|
||||
* %ccr reads block for about 128 cycles, 1 << 7 == 128) We write the
|
||||
* whole amount we want to block into the pause register, rather than
|
||||
* loop writing 128 each time.
