Provide a new solution to replace the reverted commit ac2dc29e ("perf stat: Add default hybrid events") For the default software attrs, nothing is changed. For the default hardware attrs, create a new evsel for each hybrid pmu. With the new solution, adding a new default attr will not require the special support for the hybrid platform anymore. Also, the "--detailed" is supported on the hybrid platform With the patch, $ perf stat -a -ddd sleep 1 Performance counter stats for 'system wide': 32,231.06 msec cpu-clock # 32.056 CPUs utilized 529 context-switches # 16.413 /sec 32 cpu-migrations # 0.993 /sec 69 page-faults # 2.141 /sec 176,754,151 cpu_core/cycles/ # 5.484 M/sec (41.65%) 161,695,280 cpu_atom/cycles/ # 5.017 M/sec (49.92%) 48,595,992 cpu_core/instructions/ # 1.508 M/sec (49.98%) 32,363,337 cpu_atom/instructions/ # 1.004 M/sec (58.26%) 10,088,639 cpu_core/branches/ # 313.010 K/sec (58.31%) 6,390,582 cpu_atom/branches/ # 198.274 K/sec (58.26%) 846,201 cpu_core/branch-misses/ # 26.254 K/sec (66.65%) 676,477 cpu_atom/branch-misses/ # 20.988 K/sec (58.27%) 14,290,070 cpu_core/L1-dcache-loads/ # 443.363 K/sec (66.66%) 9,983,532 cpu_atom/L1-dcache-loads/ # 309.749 K/sec (58.27%) 740,725 cpu_core/L1-dcache-load-misses/ # 22.982 K/sec (66.66%) <not supported> cpu_atom/L1-dcache-load-misses/ 480,441 cpu_core/LLC-loads/ # 14.906 K/sec (66.67%) 326,570 cpu_atom/LLC-loads/ # 10.132 K/sec (58.27%) 329 cpu_core/LLC-load-misses/ # 10.208 /sec (66.68%) 0 cpu_atom/LLC-load-misses/ # 0.000 /sec (58.32%) <not supported> cpu_core/L1-icache-loads/ 21,982,491 cpu_atom/L1-icache-loads/ # 682.028 K/sec (58.43%) 4,493,189 cpu_core/L1-icache-load-misses/ # 139.406 K/sec (33.34%) 4,711,404 cpu_atom/L1-icache-load-misses/ # 146.176 K/sec (50.08%) 13,713,090 cpu_core/dTLB-loads/ # 425.462 K/sec (33.34%) 9,384,727 cpu_atom/dTLB-loads/ # 291.170 K/sec (50.08%) 157,387 cpu_core/dTLB-load-misses/ # 4.883 K/sec (33.33%) 108,328 cpu_atom/dTLB-load-misses/ # 3.361 K/sec (50.08%) <not supported> cpu_core/iTLB-loads/ <not supported> cpu_atom/iTLB-loads/ 37,655 cpu_core/iTLB-load-misses/ # 1.168 K/sec (33.32%) 61,661 cpu_atom/iTLB-load-misses/ # 1.913 K/sec (50.03%) <not supported> cpu_core/L1-dcache-prefetches/ <not supported> cpu_atom/L1-dcache-prefetches/ <not supported> cpu_core/L1-dcache-prefetch-misses/ <not supported> cpu_atom/L1-dcache-prefetch-misses/ 1.005466919 seconds time elapsed Signed-off-by:

Current perf stat uses the evlist__add_default_attrs() to add the generic default attrs, and uses arch_evlist__add_default_attrs() to add the Arch specific default attrs, e.g., Topdown for x86. It works well for the non-hybrid platforms. However, for a hybrid platform, the hard code generic default attrs don't work. Uses arch_evlist__add_default_attrs() to replace the evlist__add_default_attrs(). The arch_evlist__add_default_attrs() is modified to invoke the same __evlist__add_default_attrs() for the generic default attrs. No functional change. Add default_null_attrs[] to indicate the arch specific attrs. No functional change for the arch specific default attrs either. Signed-off-by:

The commit 55bcf6ef ("perf: Extend PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE") extends the two types to become PMU aware types for a hybrid system. However, current evsel__hw_name doesn't take the PMU type into account. It mistakenly returns the "unknown-hardware" for the hardware event with a specific PMU type. Add an arch specific arch_evsel__hw_name() to specially handle the PMU aware hardware event. Currently, the extend PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE is only supported by X86. Only implement the specific arch_evsel__hw_name() for X86 in the patch. Nothing is changed for the other archs. Signed-off-by:

This reverts commit Fixes: ac2dc29e ("perf stat: Add default hybrid events") Between this patch and the reverted patch, the commit 6c191289 ("perf parse-events: Rename parse_events_error functions") and the commit 07eafd4e ("perf parse-event: Add init and exit to parse_event_error") clean up the parse_events_error_*() codes. The related change is also reverted. The reverted patch is hard to be extended to support new default events, e.g., Topdown events, and the existing "--detailed" option on a hybrid platform. A new solution will be proposed in the following patch to enable the perf stat default on a hybrid platform. Signed-off-by:

On linux-next tree 'perf test 95' ("Check branch stack sampling") was added recently. s390 does not support branch sampling at all and the test case fails despite for checking branch support before hand. The check for support of branching uses the software event named "dummy", as seen in the line: perf record -b -o- -e dummy -B true > /dev/null 2>&1 || exit 2 However when the branch recording is actually done, a different event is used, as seen in the line: perf record -o $TMPDIR/... --branch-filter any,save_type,u -- ... The event is omitted and for "perf record" the default event is cycles, which is not supported by s390 and this fails when executed on s390: # perf record --branch-filter any,save_type,u -- /tmp/__perf_test.program.iDSmQ/a.out Error: cycles: PMU Hardware or event type doesn't support branch stack sampling. # Therefore fix this and use the same event cycles for testing support and actually running the test. Output before: # ./perf test -Fv 95 95: Check branch stack sampling : --- start --- Testing user branch stack sampling ---- end ---- Check branch stack sampling: FAILED! # Output after: # ./perf test -Fv 95 95: Check branch stack sampling : --- start --- ---- end ---- Check branch stack sampling: Skip # Fixes: b55878c9 ("perf test: Add test for branch stack sampling") Reviewed-by:James Clark <james.clark@arm.com> Signed-off-by:

Add PMU events for the Arm Cortex-A78C and Arm Cortex-X1C CPUs. Events for Arm Cortex-A78C match those for Arm Cortex-A78. Events for Arm Cortex-X1C match those for Arm Cortex- X1. As such, this is just a mapfile change. Main ID Register (MIDR) and event data is sourced from the corresponding Arm Technical Reference Manuals: Arm Cortex-A78C: https://developer.arm.com/documentation/102226/ Arm Cortex-X1C: https://developer.arm.com/documentation/101968/Reviewed-by:

I've been in Alibaba Cloud for more than one year, mainly to address cloud-native challenges (such as high-performance container images) for open source communities. Update my email addresses on behalf of my current employer (Alibaba Cloud) to support all my (team) work in this area. Also add an outdated @redhat.com address of me.

Commit 824ddc60 ("userfaultfd: provide unmasked address on page-fault") was introduced to fix an old bug, in which the offset in the address of a page-fault was masked. Concerns were raised - although were never backed by actual code - that some userspace code might break because the bug has been around for quite a while. To address these concerns a new flag was introduced, and only when this flag is set by the user, userfaultfd provides the exact address of the page-fault. The commit however had a bug, and if the flag is unset, the offset was always masked based on a base-page granularity. Yet, for huge-pages, the behavior prior to the commit was that the address is masked to the huge-page granulrity. While there are no reports on real breakage, fix this issue. If the flag is unset, use the address with the masking that was done before.
