[PATCH v2] Additional X-Gene 1 performance events

The initial OProfile X-Gene 1 support only had the ARMv8 generic
performance events.  There are many additional microarchitecture
performance events listed for X-Gene 1 at:

https://github.com/AppliedMicro/ENGLinuxLatest/blob/apm_linux_v3.17-rc4/Documentation/arm64/xgene_pmu.txt

This patch adds those X-Gene 1 specific events.

Why does operf seems stop working after several samplings?

Hi All, 

I use oprofile to try profile the database server's (MySQL) performance.

I start with this command before I start my test:
sudo nohup operf --pid `pgrep mysqld` &

All the tests will be run for 150s.

When the CPU utilization is low, the sample number seems reasonable.
However, when the CPU utilization is very high, more than 100%, the sample number decreases dramatically.

The total sample numbers are 42417612 samples and 1226 samples, for 70% CPU utilization and 100% CPU utilization.

I find when I use opreport to get the counts in the course of the testing, the number of counts never changed. I think the oprofile stops working after several samplings.

I first try different reset counts. I find when this value is small, I can get more samplings.

I also try perf. It works well. The sampling number becomes larger as time goes on.

Any advice?

Thanks,
TIm

+#
+name:core_reject_l2q type:mandatory default:0x0
+	0x0 extra: all Counts the number of demand and L1 prefetcher requests rejected by the L2Q due to a full or
nearly full condition which likely indicates back pressure from L2Q. It also counts requests that would
have gone directly to the XQ, but are rejected due to a full or nearly full condition, indicating back
pressure from the IDI link. The L2Q may also reject transactions from a core to insure fairness between
cores, or to delay a core's dirty eviction when the address conflicts with incoming external snoops.
+name:decode_restriction type:mandatory default:0x1
+	0x1 extra: predecode_wrong Counts the number of times the prediction (from the predecode cache) for
instruction length is incorrect.
+name:dl1 type:mandatory default:0x1
+	0x1 extra: dirty_eviction Counts when a modified (dirty) cache line is evicted from the data L1 cache and
needs to be written back to memory.  No count will occur if the evicted line is clean, and hence does not
require a writeback.
+name:fetch_stall type:mandatory default:0x2
+	0x2 extra: icache_fill_pending_cycles Counts the number of cycles fetch stalls because of an icache
miss. This is a cummulative count of cycles stalled for all icache misses.
+name:itlb type:mandatory default:0x4
+	0x4 extra: miss Counts the number of times the machine was unable to find a translation in the Instruction
Translation Lookaside Buffer (ITLB) for a linear address of an instruction fetch.  It counts when new
translation are filled into the ITLB.  The event is speculative in nature, but will not count translations
(page walks) that are begun and not finished, or translations that are finished but not filled into the ITLB.
+name:l2_reject_xq type:mandatory default:0x0
+	0x0 extra: all Counts the number of demand and prefetch transactions that the L2 XQ rejects due to a full or
near full condition which likely indicates back pressure from the intra-die interconnect (IDI) fabric.
The XQ may reject transactions from the L2Q (non-cacheable requests), L2 misses and L2 write-back victims.
+name:ms_decoded type:mandatory default:0x1
+	0x1 extra: ms_entry Counts the number of times the Microcde Sequencer (MS) starts a flow of uops from the
MSROM. It does not count every time a uop is read from the MSROM.  The most common case that this counts is when
a micro-coded instruction is encountered by the front end of the machine.  Other cases include when an
instruction encounters a fault, trap, or microcode assist of any sort that initiates a flow of uops.  The
event will count MS startups for uops that are speculative, and subsequently cleared by branch
mispredict or a machine clear.
+name:uops_issued type:mandatory default:0x0
+	0x0 extra: any Counts uops issued by the front end and allocated into the back end of the machine.  This
event counts uops that retire as well as uops that were speculatively executed but didn't retire. The sort
of speculative uops that might be counted includes, but is not limited to those uops issued in the shadow of
a miss-predicted branch, those uops that are inserted during an assist (such as for a denormal floating
point result), and (previously allocated) uops that might be canceled during a machine clear.
+name:uops_not_delivered type:mandatory default:0x0
+	0x0 extra: any This event used to measure front-end inefficiencies. I.e. when front-end of the machine
is not delivering uops to the back-end and the back-end has is not stalled. This event can be used to
identify if the machine is truly front-end bound.  When this event occurs, it is an indication that the
front-end of the machine is operating at less than its theoretical peak performance.
+name:cpu_clk_unhalted type:exclusive default:core
+	0x2 extra: core Counts the number of core cycles while the core is not in a halt state.  The core enters the
halt state when it is running the HLT instruction. In mobile systems the core frequency may change from
time to time. For this reason this event may have a changing ratio with regards to time.  This event uses
fixed counter 1.  You cannot collect a PEBs record for this event.
+	0x1 extra: ref_tsc Counts the number of reference cycles that the core is not in a halt state. The core
enters the halt state when it is running the HLT instruction.  In mobile systems the core frequency may
change from time.  This event is not affected by core frequency changes but counts as if the core is running
at the maximum frequency all the time.  This event uses fixed counter 2.  You cannot collect a PEBs record for
this event
+	0x0 extra: core_p Core cycles when core is not halted.  This event uses a (_P)rogrammable general purpose
performance counter.
+	0x1 extra: ref Reference cycles when core is not halted.  This event uses a (_P)rogrammable general
purpose performance counter.
+name:ld_blocks type:exclusive default:all_block
+	0x10 extra: all_block Counts anytime a load that retires is blocked for any reason.
+	0x10 extra:pebs all_block_pebs Counts anytime a load that retires is blocked for any reason.
+	0x8 extra: utlb_miss Counts loads blocked because they are unable to find their physical address in the
micro TLB (UTLB).
+	0x8 extra:pebs utlb_miss_pebs Counts loads blocked because they are unable to find their physical
address in the micro TLB (UTLB).
+	0x1 extra: data_unknown Counts a load blocked from using a store forward, but did not occur because the
store data was not available at the right time.  The forward might occur subsequently when the data is available.
+	0x1 extra:pebs data_unknown_pebs Counts a load blocked from using a store forward, but did not occur
because the store data was not available at the right time.  The forward might occur subsequently when the
data is available.
+	0x4 extra: u4k_alias Counts loads that block because their address modulo 4K matches a pending store.
+	0x4 extra:pebs u4k_alias_pebs Counts loads that block because their address modulo 4K matches a
pending store.
+name:page_walks type:exclusive default:0x1
+	0x1 extra: d_side_cycles Counts every core cycle when a Data-side walks (due to data operation) page
walk is in progress.
+	0x2 extra: i_side_cycles Counts every core cycle when a Instruction-side (walks due to an instruction
fetch) page walk is in progress.
+	0x3 extra: cycles Counts every core cycle a page-walk is in progress due to either a data memory operation
or an instruction fetch.
+name:misalign_mem_ref type:exclusive default:load_page_split
+	0x2 extra: load_page_split Counts when a memory load of a uop spans a page boundary (a split) is retired.
+	0x2 extra:pebs load_page_split_pebs Counts when a memory load of a uop spans a page boundary (a split) is retired.
+	0x4 extra: store_page_split Counts when a memory store of a uop spans a page boundary (a split) is retired.
+	0x4 extra:pebs store_page_split_pebs Counts when a memory store of a uop spans a page boundary (a split)
is retired.
+name:longest_lat_cache type:exclusive default:0x4f
+	0x4f extra: reference Counts memory requests originating from the core that reference a cache line in
the L2 cache.
+	0x41 extra: miss Counts memory requests originating from the core that miss in the L2 cache.
+name:icache type:exclusive default:0x1
+	0x1 extra: hit Counts each cache line access to the Icache that are fulfilled (hit) by the Icache
+	0x2 extra: misses Counts each cache line access to the Icache that are not fullfilled (miss) by the Icache
+	0x3 extra: accesses Counts each cache line access to the Icache
+name:inst_retired type:exclusive default:any
+	0x0 extra: any Counts the number of instructions that retire execution. For instructions that consist
of multiple uops, this event counts the retirement of the last uop of the instruction. The counter
continues counting during hardware interrupts, traps, and inside interrupt handlers.  This event uses
fixed counter 0.  You cannot collect a PEBs record for this event
+	0x0 extra: any_p Counts the number of instructions that retire execution. For instructions that
consist of multiple uops, this event counts the retirement of the last uop of the instruction. The event
continues counting during hardware interrupts, traps, and inside interrupt handlers.  This is an
architectural performance event.  This event uses a (_P)rogrammable general purpose performance counter.
+	0x0 extra:pebs any_pebs Counts the number of instructions that retire execution. For instructions
that consist of multiple uops, this event counts the retirement of the last uop of the instruction. The
event continues counting during hardware interrupts, traps, and inside interrupt handlers.  This is an
architectural performance event.  This event uses a (_P)rogrammable general purpose performance
counter. *This event is Precise Event capable:  The EventingRIP field in the PEBS record is precise to the
address of the instruction which caused the event.  Note: Because PEBS records can be collected only on
IA32_PMC0, only one event can use the PEBS facility at a time.
+name:uops_retired type:exclusive default:any
+	0x0 extra: any Counts uops which retired
+	0x0 extra:pebs any_pebs Counts uops which retired
+	0x1 extra: ms Counts uops retired that are from the complex flows issued by the micro-sequencer (MS). 
Counts both the uops from a micro-coded instruction, and the uops that might be generated from a
micro-coded assist.
+	0x1 extra:pebs ms_pebs Counts uops retired that are from the complex flows issued by the
micro-sequencer (MS).  Counts both the uops from a micro-coded instruction, and the uops that might be
generated from a micro-coded assist.
+	0x8 extra: fpdiv Counts the number of floating point divide uops retired.
+	0x8 extra:pebs fpdiv_pebs Counts the number of floating point divide uops retired.
+	0x10 extra: idiv Counts the number of integer divide uops retired.
+	0x10 extra:pebs idiv_pebs Counts the number of integer divide uops retired.
+name:machine_clears type:exclusive default:0x0
+	0x0 extra: all Counts machine clears for any reason
+	0x1 extra: smc Counts the number of times that the processor detects that a program is writing to a code
section and has to perform a machine clear because of that modification.  Self-modifying code (SMC)
causes a severe penalty in all Intel architecture processors.
+	0x2 extra: memory_ordering Counts machine clears due to memory ordering issues.  This occurs when a
snoop request happens and the machine is uncertain if memory ordering will be preserved, as another core
is in the process of modifying the data.
+	0x4 extra: fp_assist Counts machine clears due to floating point (FP) operations needing assists.  For
instance, if the result was a floating point denormal, the hardware clears the pipeline and reissues uops
to produce the correct IEEE compliant denormal result.
+	0x8 extra: disambiguation Counts machine clears due to memory disambiguation.  Memory disambiguation
happens when a load which has been issued conflicts with a previous unretired store in the pipeline whose
address was not known at issue time, but is later resolved to be the same as the load address.
+name:br_inst_retired type:exclusive default:all_branches
+	0x0 extra: all_branches Counts branch instructions retired for all branch types.  This is an
architectural performance event.
+	0x0 extra:pebs all_branches_pebs Counts branch instructions retired for all branch types.  This is an
architectural performance event.
+	0x7e extra: jcc Counts retired Jcc (Jump on Conditional Code/Jump if Conditon is Met) branch
instructions retired, including both when the branch was taken and when it was not taken.
+	0x7e extra:pebs jcc_pebs Counts retired Jcc (Jump on Conditional Code/Jump if Conditon is Met) branch
instructions retired, including both when the branch was taken and when it was not taken.
+	0xfe extra: taken_jcc Counts Jcc (Jump on Conditional Code/Jump if Conditon is Met) branch
instructions retired that were taken and does not count when the Jcc branch instruction were not taken.
+	0xfe extra:pebs taken_jcc_pebs Counts Jcc (Jump on Conditional Code/Jump if Conditon is Met) branch
instructions retired that were taken and does not count when the Jcc branch instruction were not taken.
+	0xf9 extra: call Counts near CALL branch instructions retired.
+	0xf9 extra:pebs call_pebs Counts near CALL branch instructions retired.
+	0xfd extra: rel_call Counts near relative CALL branch instructions retired.
+	0xfd extra:pebs rel_call_pebs Counts near relative CALL branch instructions retired.

+	0xeb extra: non_return_ind Counts near indirect call or near indirect jmp branch instructions retired.
+	0xeb extra:pebs non_return_ind_pebs Counts near indirect call or near indirect jmp branch
instructions retired.
+	0xbf extra: far_branch Counts far branch instructions retired.  This includes far jump, far call and
return, and Interrupt call and return.  Intel Architecture uses far branches to transition to a different
privilege level (ex: kernel/user).
+	0xbf extra:pebs far_branch_pebs Counts far branch instructions retired.  This includes far jump, far
call and return, and Interrupt call and return.  Intel Architecture uses far branches to transition to a
different privilege level (ex: kernel/user).
+name:br_misp_retired type:exclusive default:all_branches
+	0x0 extra: all_branches Counts mispredicted branch instructions retired including all branch types.
+	0x0 extra:pebs all_branches_pebs Counts mispredicted branch instructions retired including all
branch types.
+	0x7e extra: jcc Counts mispredicted retired Jcc (Jump on Conditional Code/Jump if Conditon is Met)
branch instructions retired, including both when the branch was supposed to be taken and when it was not
supposed to be taken (but the processor predicted the opposite condition).
+	0x7e extra:pebs jcc_pebs Counts mispredicted retired Jcc (Jump on Conditional Code/Jump if Conditon
is Met) branch instructions retired, including both when the branch was supposed to be taken and when it
was not supposed to be taken (but the processor predicted the opposite condition).
+	0xfe extra: taken_jcc Counts mispredicted retired Jcc (Jump on Conditional Code/Jump if Condition is
Met) branch instructions retired that were supposed to be taken but the processor predicted that it would
not be taken.
+	0xfe extra:pebs taken_jcc_pebs Counts mispredicted retired Jcc (Jump on Conditional Code/Jump if
Condition is Met) branch instructions retired that were supposed to be taken but the processor predicted
that it would not be taken.
+	0xfb extra: ind_call Counts mispredicted near indirect CALL branch instructions retired, where the
target address taken was not what the processor  predicted.
+	0xfb extra:pebs ind_call_pebs Counts mispredicted near indirect CALL branch instructions retired,
where the target address taken was not what the processor  predicted.
+	0xf7 extra: return Counts mispredicted near RET branch instructions retired, where the return address
taken was not what the processor  predicted.
+	0xf7 extra:pebs return_pebs Counts mispredicted near RET branch instructions retired, where the
return address taken was not what the processor  predicted.

call or near indirect jmp, where the target address taken was not what the processor predicted.
+	0xeb extra:pebs non_return_ind_pebs Counts mispredicted branch instructions retired that were near
indirect call or near indirect jmp, where the target address taken was not what the processor predicted.
+name:issue_slots_not_consumed type:exclusive default:0x0
+	0x0 extra: any Counts the number of issue slots per core cycle that were not consumed by the backend due to
either a full resource  in the backend (RESOURCE_FULL) or due to the processor recovering from some event (RECOVERY)
+	0x1 extra: resource_full Counts the number of issue slots per core cycle that were not consumed because
of a full resource in the backend.  Including but not limited the Re-order Buffer (ROB), reservation
stations (RS), load/store buffers, physical registers, or any other needed machine resource that is
currently unavailable.   Note that uops must be available for consumption in order for this event to fire. 
If a uop is not available (Instruction Queue is empty), this event will not count.
+	0x2 extra: recovery Counts the number of issue slots per core cycle that were not consumed by the backend
because allocation is stalled waiting for a mispredicted jump to retire or other branch-like conditions
(e.g. the event is relevant during certain microcode flows).   Counts all issue slots blocked while within
this window including slots where uops were not available in the Instruction Queue.
+name:hw_interrupts type:exclusive default:0x1

+	0x12 extra: dtlb_miss_stores Counts store uops retired that caused a DTLB miss.
+	0x12 extra:pebs dtlb_miss_stores_pebs Counts store uops retired that caused a DTLB miss.
+	0x13 extra: dtlb_miss Counts uops retired that had a DTLB miss on load, store or either.  Note that when two
distinct memory operations to the same page miss the DTLB, only one of them will be recorded as a DTLB miss.
+	0x13 extra:pebs dtlb_miss_pebs Counts uops retired that had a DTLB miss on load, store or either.  Note
that when two distinct memory operations to the same page miss the DTLB, only one of them will be recorded as
a DTLB miss.
+	0x21 extra: lock_loads Counts locked memory uops retired.  This includes "regular" locks and bus locks.
(To specifically count bus locks only, see the Offcore response event.)  A locked access is one with a lock
prefix, or an exchange to memory.  See the SDM for a complete description of which memory load accesses are locks.

+	0x41 extra: split_loads Counts load uops retired where the data requested spans a 64 byte cache line boundry.
+	0x41 extra:pebs split_loads_pebs Counts load uops retired where the data requested spans a 64 byte
cache line boundry.
+	0x42 extra: split_stores Counts store uops retired where the data requested spans a 64 byte cache line boundry.
+	0x42 extra:pebs split_stores_pebs Counts store uops retired where the data requested spans a 64 byte
cache line boundry.
+	0x43 extra: split Counts memory uops retired where the data requested spans a 64 byte cache line boundry.
+	0x43 extra:pebs split_pebs Counts memory uops retired where the data requested spans a 64 byte cache
line boundry.
+name:mem_load_uops_retired type:exclusive default:l1_hit

+	0x10 extra:pebs l2_miss_pebs Counts load uops retired that miss in the L2 cache
+	0x20 extra: hitm Counts load uops retired where the cache line containing the data was in the modified
state of another core or modules cache (HITM).  More specifically, this means that when the load address
was checked by other caching agents (typically another processor) in the system, one of those caching
agents indicated that they had a dirty copy of the data.  Loads that obtain a HITM response incur greater
latency than most is typical for a load.  In addition, since HITM indicates that some other processor had
this data in its cache, it implies that the data was shared between processors, or potentially was a lock or
semaphore value.  This event is useful for locating sharing, false sharing, and contended locks.

+	0x40 extra: wcb_hit Counts memory load uops retired where the data is retrieved from the WCB (or fill
buffer), indicating that the load found its data while that data was in the process of being brought into
the L1 cache.  Typically a load will receive this indication when some other load or prefetch missed the L1
cache and was in the process of retrieving the cache line containing the data , but that process had not yet
finished (and written the data back to the cache).  For example, consider load X and Y, both referencing the
same cache line that is not in the L1 cache.  If load X misses cache first, it obtains and WCB (or fill buffer)
and begins the process of requesting the data.  When load Y requests the data, it will either hit the WCB, or
the L1 cache, depending on exactly what ti
 me the request to Y occurs.

(or fill buffer), indicating that the load found its data while that data was in the process of being
brought into the L1 cache.  Typically a load will receive this indication when some other load or prefetch

WCB (or fill buffer) and begins the process of requesting the data.  When load Y requests the data, it will
either hit the WCB, or the L1 cache, depending on exactl
 y what time the request to Y occurs.
+	0x80 extra: dram_hit Counts memory load uops retired where the data is retrieved from DRAM.  Event is
counted at retirment, so the speculative loads are ignored.  A memory load can hit (or miss) the L1 cache,
hit (or miss) the L2 cache, hit DRAM, hit in the WCB or receive a HITM response.
