Process the JSONs to find support for "system" events, which are not
tied to a specific CPUID.
A "COMPAT" property is now used to match against the namespace ID from
the kernel PMU driver.
The generated pmu-events.c will now have 2 tables:
a. CPU events, as before.
b. New pmu_sys_event_tables[] table, which will have events matched to
specific SoCs.
It will look like this:
struct pmu_event pme_hisilicon_hip09_sys[] = {
{
.name = "cycles",
.compat = "0x00030736",
.event = "event=0",
.desc = "Clock cycles",
.topic = "smmu v3 pmcg",
.long_desc = "Clock cycles",
},
{
.name = "smmuv3_pmcg.l1_tlb",
.compat = "0x00030736",
.event = "event=0x8a",
.desc = "SMMUv3 PMCG l1_tlb. Unit: smmuv3_pmcg ",
.topic = "smmu v3 pmcg",
.long_desc = "SMMUv3 PMCG l1_tlb",
.pmu = "smmuv3_pmcg",
},
...
};
struct pmu_event pme_arm_cortex_a53[] = {
{
.name = "ext_mem_req",
.event = "event=0xc0",
.desc = "External memory request",
.topic = "memory",
},
{
.name = "ext_mem_req_nc",
.event = "event=0xc1",
.desc = "Non-cacheable external memory request",
.topic = "memory",
},
...
};
struct pmu_event pme_hisilicon_hip09_cpu[] = {
{
.name = "l2d_cache_refill_wr",
.event = "event=0x53",
.desc = "L2D cache refill, write",
.topic = "core imp def",
.long_desc = "Attributable Level 2 data cache refill, write",
},
...
};
struct pmu_events_map pmu_events_map[] = {
{
.cpuid = "0x00000000410fd030",
.version = "v1",
.type = "core",
.table = pme_arm_cortex_a53
},
{
.cpuid = "0x00000000480fd010",
.version = "v1",
.type = "core",
.table = pme_hisilicon_hip09_cpu
},
{
.table = 0
},
};
struct pmu_event pme_hisilicon_hip09_cpu[] = {
{
.name = "uncore_hisi_l3c.rd_cpipe",
.event = "event=0",
.desc = "Total read accesses. Unit: hisi_sccl,l3c ",
.topic = "uncore l3c",
.long_desc = "Total read accesses",
.pmu = "hisi_sccl,l3c",
},
{
.name = "uncore_hisi_l3c.wr_cpipe",
.event = "event=0x1",
.desc = "Total write accesses. Unit: hisi_sccl,l3c ",
.topic = "uncore l3c",
.long_desc = "Total write accesses",
.pmu = "hisi_sccl,l3c",
},
...
};
struct pmu_sys_events pmu_sys_event_tables[] = {
{
.table = pme_hisilicon_hip09_sys,
},
...
};
Committer notes:
Added the fix for architectures without PMU events, provided by John
after I reported the build failing in such systems.

Currently only upto a level 2 directory is supported, in form
vendor/platform.
Add support for a further level, to support vendor/platform
sub-directories in future, which will be vendor/platform/cpu and
vendor/platform/sys.

sample_type bit
Before we had this unhelpful message:
$ perf record --data-page-size sleep 1
Error:
The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (cycles:u).
/bin/dmesg | grep -i perf may provide additional information.

Add support to the perf_missing_features variable to remember what
caused evsel__open() to fail and then use that information in
evsel__open_strerror().
$ perf record --data-page-size sleep 1
Error:
Asking for the data page size isn't supported by this kernel.

elfutils needs to be provided main binary and separate debug info file
respectively. Providing separate debug info file instead of the main
binary is not sufficient.
One needs to try both supplied filename and its possible cache by its
build-id depending on the use case.

When using 'perf record's option '-I' or '--user-regs=' along with
argument '?' to list available register names, memory of variable 'os'
allocated by strdup() needs to be released before __parse_regs()
returns, otherwise memory leak will occur.

Commit e1c92a7fbbc5 ("perf tests: Add another metric parsing test") add
another test for metric parsing. The test goes through all metrics
compiled for arch within pmu events and try to parse them.
Right now this test is failing in powerpc machine.
Result in power9 platform:
[command]# ./perf test 10
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Skip (some metrics failed)
10.4: Parsing of PMU event table metrics with fake PMUs : FAILED!
Issue is we are passing different runtime parameter value in
"expr__find_other" and "expr__parse" function which is called from
function `metric_parse_fake`. And because of this parsing of hv-24x7
metrics is failing.
[command]# ./perf test 10 -vv
.....
hv_24x7/pm_mcs01_128b_rd_disp_port01,chip=1/ not found
expr__parse failed
test child finished with -1
---- end ----
PMU events subtest 4: FAILED!
This patch fix this issue and change runtime parameter value to '0' in
expr__parse function.
Result in power9 platform after this patch:
[command]# ./perf test 10
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Skip (some metrics failed)
10.4: Parsing of PMU event table metrics with fake PMUs : Ok

It calculates IPC from the cycles and instruction counts and compares it
with the shadow stat for both global aggregation (default) and no
aggregation mode.
$ perf stat -a -A -e cycles,instructions sleep 1
Performance counter stats for 'system wide':
CPU0 39,580,880 cycles
CPU1 45,426,945 cycles
CPU2 31,151,685 cycles
CPU3 55,167,421 cycles
CPU0 17,073,564 instructions # 0.43 insn per cycle
CPU1 34,955,764 instructions # 0.77 insn per cycle
CPU2 15,688,459 instructions # 0.50 insn per cycle
CPU3 34,699,217 instructions # 0.63 insn per cycle
1.003275495 seconds time elapsed
In this example, the 'insn per cycle' should be matched to the number
for each cpu. For CPU2, 0.50 = 15,688,459 / 31,151,685 .
Committer testing:
# perf test shadow
78: perf stat metrics (shadow stat) test : Ok

Pull locking fixes from Thomas Gleixner:
"Two more places which invoke tracing from RCU disabled regions in the
idle path.
Similar to the entry path the low level idle functions have to be
non-instrumentable"
* tag 'locking-urgent-2020-11-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
intel_idle: Fix intel_idle() vs tracing
sched/idle: Fix arch_cpu_idle() vs tracing

Pull irq fixes from Thomas Gleixner:
"Two fixes for irqchip drivers:
- Save and restore the GICV3 ITS state unconditionally on
suspend/resume to handle firmware which fails to do so.
- Use the correct index into the fwspec parameters to read the irq
trigger type in the EXIU chip driver"

irqchip/gic-v3-its: Unconditionally save/restore the ITS state on suspend
irqchip/exiu: Fix the index of fwspec for IRQ type

Pull EFI fixes from Borislav Petkov:
"More EFI fixes forwarded from Ard Biesheuvel:
- revert efivarfs kmemleak fix again - it was a false positive
- make CONFIG_EFI_EARLYCON depend on CONFIG_EFI explicitly so it does
not pull in other dependencies unnecessarily if CONFIG_EFI is not
set
- defer attempts to load SSDT overrides from EFI vars until after the
efivar layer is up"
* tag 'efi-urgent-for-v5.10-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
efi: EFI_EARLYCON should depend on EFI
efivarfs: revert "fix memory leak in efivarfs_create()"
efi/efivars: Set generic ops before loading SSDT

Pull x86 fixes from Borislav Petkov:
"A couple of urgent fixes which accumulated this last week:
- Two resctrl fixes to prevent refcount leaks when manipulating the
resctrl fs (Xiaochen Shen)
- Correct prctl(PR_GET_SPECULATION_CTRL) reporting (Anand K Mistry)
- A fix to not lose already seen MCE severity which determines
whether the machine can recover (Gabriele Paoloni)"
* tag 'x86_urgent_for_v5.10-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/mce: Do not overwrite no_way_out if mce_end() fails
x86/speculation: Fix prctl() when spectre_v2_user={seccomp,prctl},ibpb
x86/resctrl: Add necessary kernfs_put() calls to prevent refcount leak
x86/resctrl: Remove superfluous kernfs_get() calls to prevent refcount leak

Pull RISC-V fixes from Palmer Dabbelt:
"I've collected a handful of fixes over the past few weeks:
- A fix to un-break the build-id argument to the vDSO build, which is
necessary for the LLVM linker.
- A fix to initialize the jump label subsystem, without which it (and
all the stuff that uses it) doesn't actually function.
- A fix to include <asm/barrier.h> from <vdso/processor.h>, without
which some drivers won't compile"
* tag 'riscv-for-linus-5.10-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux:
RISC-V: fix barrier() use in <vdso/processor.h>
RISC-V: Add missing jump label initialization
