Abstract: Systems and methods for efficiently protecting simultaneous access to user-space shared data by multiple threads using a kernel structure is disclosed. Further, a mechanism within a spinlock allows reduction of the performance and power interference associated with the improved spinlock. This allows a thread in the critical section to complete its execution sooner by increasing the frequency and voltage of the CPU core it runs on. The improved spinlock allows a thread to enter a power saving state and the critical section to instruct a PCU to allocate a headroom power budget exclusively to the core that executed the instruction. The improved spinlock also provides saving in dynamic power during clock gated of the CPU resources and dynamic and static power during power gated of the CPU resources.

Abstract: A system and method of a snoop filter providing larger address space coverage, freeing back-invalidation when an entry is evicted, and freeing excessive snoops when a snoop has a miss is provided. The snoop filter tracks the addresses of upper level cache lines at region basis, which enables a relatively smaller snoop filter with much larger address space coverage. The snoop filter is non-inclusive. The snoop filter is designed such that each upper level cache has its own bloom filter to track address space occupancy, eliminating a significant portion of conflict misses. The snoop filter is designed at a larger granularity such that applications have a much better spatial locality. The larger granularity employs coarse grain tracking techniques, which allow monitor of large regions of memory and use that infoiivation to avoid unnecessary broadcasts and filter unnecessary cache tag lookups, thus improving system performance and power consumption.
