name:ld_blocks type:exclusive default:0x2
	0x2 extra: store_forward This event counts how many times the load operation got the true Block-on-Store blocking code preventing store forwarding. This includes cases when:  - preceding store conflicts with the load (incomplete overlap);  - store forwarding is impossible due to u-arch limitations;  - preceding lock RMW operations are not forwarded;  - store has the no-forward bit set (uncacheable/page-split/masked stores);  - all-blocking stores are used (mostly, fences and port I/O); and others. The most common case is a load blocked due to its address range overlapping with a preceding smaller uncompleted store. Note: This event does not take into account cases of out-of-SW-control (for example, SbTailHit), unknown physical STA, and cases of blocking loads on store due to being non-WB memory type or a lock. These cases are covered by other events. See the table of not supported store forwards in the Optimization Guide.
	0x8 extra: no_sr This event counts the number of times that split load operations are temporarily blocked because all resources for handling the split accesses are in use.

name:l1d_pend_miss type:exclusive default:pending
	0x1 extra: pending This event counts duration of L1D miss outstanding, that is each cycle number of Fill Buffers (FB) outstanding required by Demand Reads. FB either is held by demand loads, or it is held by non-demand loads and gets hit at least once by demand. The valid outstanding interval is defined until the FB deallocation by one of the following ways: from FB allocation, if FB is allocated by demand; from the demand Hit FB, if it is allocated by hardware or software prefetch. Note: In the L1D, a Demand Read contains cacheable or noncacheable demand loads, including ones causing cache-line splits and reads due to page walks resulted from any request type.

name:offcore_requests_outstanding type:exclusive default:demand_data_rd

Note: A prefetch promoted to Demand is counted from the promotion point.
	0x2 extra: demand_code_rd This event counts the number of offcore outstanding Code Reads transactions in the super queue every cycle. The "Offcore outstanding" state of the transaction lasts from the L2 miss until the sending transaction completion to requestor (SQ deallocation). See the corresponding Umask under OFFCORE_REQUESTS.

	0x1 extra: split_lock_uc_lock_duration This event counts cycles in which the L1 and L2 are locked due to a UC lock or split lock. A lock is asserted in case of locked memory access, due to noncacheable memory, locked operation that spans two cache lines, or a page walk from the noncacheable page table. L1D and L2 locks have a very high performance penalty and it is highly recommended to avoid such access.

name:resource_stalls type:exclusive default:0x1
	0x1 extra: any This event counts resource-related stall cycles. Reasons for stalls can be as follows:  - *any* u-arch structure got full (LB, SB, RS, ROB, BOB, LM, Physical Register Reclaim Table (PRRT), or Physical History Table (PHT) slots)  - *any* u-arch structure got empty (like INT/SIMD FreeLists)  - FPU control word (FPCW), MXCSR and others. This counts cycles that the pipeline backend blocked uop delivery from the front end.
	0x4 extra: rs This event counts stall cycles caused by absence of eligible entries in the reservation station (RS). This may result from RS overflow, or from RS deallocation because of the RS array Write Port allocation scheme (each RS entry has two write ports instead of four.
