Kan Liang 61b985e3e7 perf/x86/intel: Add perf core PMU support for Sapphire Rapids 
Add perf core PMU support for the Intel Sapphire Rapids server, which is
the successor of the Intel Ice Lake server. The enabling code is based
on Ice Lake, but there are several new features introduced.

The event encoding is changed and simplified, e.g., the event codes
which are below 0x90 are restricted to counters 0-3. The event codes
which above 0x90 are likely to have no restrictions. The event
constraints, extra_regs(), and hardware cache events table are changed
accordingly.

A new Precise Distribution (PDist) facility is introduced, which
further minimizes the skid when a precise event is programmed on the GP
counter 0. Enable the Precise Distribution (PDist) facility with :ppp
event. For this facility to work, the period must be initialized with a
value larger than 127. Add spr_limit_period() to apply the limit for
:ppp event.

Two new data source fields, data block & address block, are added in the
PEBS Memory Info Record for the load latency event. To enable the
feature,
- An auxiliary event has to be enabled together with the load latency
  event on Sapphire Rapids. A new flag PMU_FL_MEM_LOADS_AUX is
  introduced to indicate the case. A new event, mem-loads-aux, is
  exposed to sysfs for the user tool.
  Add a check in hw_config(). If the auxiliary event is not detected,
  return an unique error -ENODATA.
- The union perf_mem_data_src is extended to support the new fields.
- Ice Lake and earlier models do not support block information, but the
  fields may be set by HW on some machines. Add pebs_no_block to
  explicitly indicate the previous platforms which don't support the new
  block fields. Accessing the new block fields are ignored on those
  platforms.

A new store Latency facility is introduced, which leverages the PEBS
facility where it can provide additional information about sampled
stores. The additional information includes the data address, memory
auxiliary info (e.g. Data Source, STLB miss) and the latency of the
store access. To enable the facility, the new event (0x02cd) has to be
programed on the GP counter 0. A new flag PERF_X86_EVENT_PEBS_STLAT is
introduced to indicate the event. The store_latency_data() is introduced
to parse the memory auxiliary info.

The layout of access latency field of PEBS Memory Info Record has been
changed. Two latency, instruction latency (bit 15:0) and cache access
latency (bit 47:32) are recorded.
- The cache access latency is similar to previous memory access latency.
  For loads, the latency starts by the actual cache access until the
  data is returned by the memory subsystem.
  For stores, the latency starts when the demand write accesses the L1
  data cache and lasts until the cacheline write is completed in the
  memory subsystem.
  The cache access latency is stored in low 32bits of the sample type
  PERF_SAMPLE_WEIGHT_STRUCT.
- The instruction latency starts by the dispatch of the load operation
  for execution and lasts until completion of the instruction it belongs
  to.
  Add a new flag PMU_FL_INSTR_LATENCY to indicate the instruction
  latency support. The instruction latency is stored in the bit 47:32
  of the sample type PERF_SAMPLE_WEIGHT_STRUCT.

Extends the PERF_METRICS MSR to feature TMA method level 2 metrics. The
lower half of the register is the TMA level 1 metrics (legacy). The
upper half is also divided into four 8-bit fields for the new level 2
metrics. Expose all eight Topdown metrics events to user space.
