Thanks Sanjay :) 98512 3 anh.nguyen.pv 2024-03-18 03:39:18 +0000 Hi all, I am a new comer and I would like to investigate this ticket. But I don't know how to list out the "Auto-detecting system features:" as your comment. I tried "bitbake -f -c compile perf -DDD" Could you please share me the command to list out the "Auto-detecting system features:" Thank you Anh 98526 4 randy.macleod 2024-03-19 00:41:20 +0000 Anil has worked on the libaudit change and has a patch mostly ready to review. Anil, Please post the patch to the oe-core list and CC people asking about it here. Anil asked about how to test that perf is supporting libaudit and unfortunately, I don't know off-hand. If you want to compare to a perf that seems to support libaudit, check out the debian perf: https://packages.debian.org/bullseye/linux-perf-5.10 98535 5 5032 randy.macleod 2024-03-19 18:23:13 +0000 Created attachment 5032 Anil's libaudit patch I attached Anil's patch that he sent to me privately in Jan 2024. I hope you don't mind me sharing it Anil. 100870 6 randy.macleod 2025-02-06 16:25:28 +0000 Needs some kernel knowledge. If anyone wants to work on this please ask for help from me and I'll try to make time. 102797 7 randy.macleod 2025-09-18 14:55:44 +0000 It has been a while and no one has implemented this enhancment. I can only conclude that it's a 'nice-to-have' feature rather than a real need. If anyone has a real need to enhance how perf is configure, they can send a patch. 5032 2024-03-19 18:23:13 +0000 2024-03-19 18:23:13 +0000 Anil's libaudit patch libaudit.patch text/plain 2960 randy.macleod ZGlmZiAtLWdpdCBhL21ldGEvcmVjaXBlcy1rZXJuZWwvcGVyZi9wZXJmLmJiIGIvbWV0YS9yZWNp cGVzLWtlcm5lbC9wZXJmL3BlcmYuYmIKaW5kZXggMzI4ODJhZmRmNC4uYWRhNmJkMDI3OCAxMDA2 NDQKLS0tIGEvbWV0YS9yZWNpcGVzLWtlcm5lbC9wZXJmL3BlcmYuYmIKKysrIGIvbWV0YS9yZWNp cGVzLWtlcm5lbC9wZXJmL3BlcmYuYmIKQEAgLTEwLDcgKzEwLDcgQEAgSE9NRVBBR0UgPSAiaHR0 cHM6Ly9wZXJmLndpa2kua2VybmVsLm9yZy9pbmRleC5waHAvTWFpbl9QYWdlIgogTElDRU5TRSA9 ICJHUEwtMi4wLW9ubHkiCiAKIAotUEFDS0FHRUNPTkZJRyA/Pz0gInB5dGhvbiB0dWkgbGlidW53 aW5kIGxpYnRyYWNlZXZlbnQiCitQQUNLQUdFQ09ORklHID8/PSAiIHNjcmlwdGluZyBweXRob24z IHR1aSBsaWJ1bndpbmQgbGlidHJhY2VldmVudCAiCiBQQUNLQUdFQ09ORklHW2R3YXJmXSA9ICIs Tk9fRFdBUkY9MSIKIFBBQ0tBR0VDT05GSUdbcGVybF0gPSAiLE5PX0xJQlBFUkw9MSxwZXJsIgog UEFDS0FHRUNPTkZJR1tweXRob25dID0gIixOT19MSUJQWVRIT049MSxweXRob24zIHB5dGhvbjMt c2V0dXB0b29scy1uYXRpdmUiCkBAIC0yNCw3ICsyNCw5IEBAIFBBQ0tBR0VDT05GSUdbYmZkXSA9 ICIsTk9fTElCQkZEPTEiCiBQQUNLQUdFQ09ORklHW3N5c3RlbXRhcF0gPSAiLE5PX1NEVD0xLHN5 c3RlbXRhcCIKIFBBQ0tBR0VDT05GSUdbanZtdGldID0gIixOT19KVk1UST0xIgogIyBsaWJhdWRp dCBzdXBwb3J0IHdvdWxkIG5lZWQgc2NyaXB0aW5nIHRvIGJlIGVuYWJsZWQKLVBBQ0tBR0VDT05G SUdbYXVkaXRdID0gIixOT19MSUJBVURJVD0xLGF1ZGl0IgorUEFDS0FHRUNPTkZJR1tzY3JpcHRp bmddID0gIixOT19MSUJQRVJMPTEscGVybCBweXRob24zIgorUEFDS0FHRUNPTkZJR1thdWRpdF0g PSAiLE5PX0xJQkFVRElUPTEsYXVkaXQgbGliYXVkaXQgcHl0aG9uMyAiCitQQUNLQUdFQ09ORklH W2xpYmF1ZGl0XSA9ICIsTk9fTElCQVVESVQ9MSxsaWJhdWRpdCIKIFBBQ0tBR0VDT05GSUdbbWFu cGFnZXNdID0gIiwseG1sdG8tbmF0aXZlIGFzY2lpZG9jLW5hdGl2ZSIKIFBBQ0tBR0VDT05GSUdb Y2FwXSA9ICIsLGxpYmNhcCIKIFBBQ0tBR0VDT05GSUdbbGlidHJhY2VldmVudF0gPSAiLE5PX0xJ QlRSQUNFRVZFTlQ9MSxsaWJ0cmFjZWV2ZW50IgpAQCAtNTQsNyArNTYsNyBAQCBQUk9WSURFUyA9 ICJ2aXJ0dWFsL3BlcmYiCiBpbmhlcml0IGxpbnV4LWtlcm5lbC1iYXNlIGtlcm5lbC1hcmNoIG1h bnBhZ2VzCiAKICMgbmVlZGVkIGZvciBidWlsZGluZyB0aGUgdG9vbHMvcGVyZiBQeXRob24gYmlu ZGluZ3MKLWluaGVyaXRfZGVmZXIgJHtAYmIudXRpbHMuY29udGFpbnMoJ1BBQ0tBR0VDT05GSUcn LCAncHl0aG9uJywgJ3B5dGhvbjN0YXJnZXRjb25maWcnLCAnJywgZCl9Citpbmhlcml0ICR7QGJi LnV0aWxzLmNvbnRhaW5zKCdQQUNLQUdFQ09ORklHJywgJ3B5dGhvbiBzY3JpcHRpbmcgYXVkaXQn LCAncHl0aG9uM3RhcmdldGNvbmZpZycsICcnLCBkKX0KIGluaGVyaXQgcHl0aG9uMy1kaXIKIGV4 cG9ydCBQWVRIT05fU0lURVBBQ0tBR0VTX0RJUgogCkBAIC0xNDAsNiArMTQyLDkgQEAgUEVSRl9T UkMgPz0gIk1ha2VmaWxlIFwKICAgICAgICAgICAgICBzY3JpcHRzLyBcCiAgICAgICAgICAgICAg YXJjaC9hcm02NC90b29scyBcCiAgICAgICAgICAgICAgYXJjaC8ke0FSQ0h9L01ha2VmaWxlIFwK KwkgICAgIGF1ZGl0IFwKKwkgICAgIGxpYmF1ZGl0IFwKKwkgICAgIGxpYmF1ZGl0LWRldiBcCiAi CiAKIFBFUkZfRVhUUkFfTERGTEFHUyA9ICIiCkBAIC0xNjUsNyArMTcwLDcgQEAgZG9faW5zdGFs bCgpIHsKIAl1bnNldCBDRkxBR1MKIAlvZV9ydW5tYWtlIGluc3RhbGwKIAkjIHdlIGFyZSBjaGVj a2luZyBmb3IgdGhpcyBtYWtlIHRhcmdldCB0byBiZSBjb21wYXRpYmxlIHdpdGggb2xkZXIgcGVy ZiB2ZXJzaW9ucwotCWlmICR7QGJiLnV0aWxzLmNvbnRhaW5zKCdQQUNLQUdFQ09ORklHJywgJ3B5 dGhvbicsICd0cnVlJywgJ2ZhbHNlJywgZCl9ICYmIGdyZXAgLXEgaW5zdGFsbC1weXRob25fZXh0 ICR7U30vdG9vbHMvcGVyZi9NYWtlZmlsZSo7IHRoZW4KKwlpZiAke0BiYi51dGlscy5jb250YWlu cygnUEFDS0FHRUNPTkZJRycsICdweXRob24gc2NyaXRpbmcgYXVkaXQnLCAndHJ1ZScsICdmYWxz ZScsIGQpfSAmJiBncmVwIC1xIGluc3RhbGwtcHl0aG9uX2V4dCAke1N9L3Rvb2xzL3BlcmYvTWFr ZWZpbGUqOyB0aGVuCiAJICAgIG9lX3J1bm1ha2UgREVTVERJUj0ke0R9IGluc3RhbGwtcHl0aG9u X2V4dAogCSAgICBpZiBbIC1lICR7RH0ke2xpYmRpcn0vcHl0aG9uKi9zaXRlLXBhY2thZ2VzL3Bl cmYtKi9TT1VSQ0VTLnR4dCBdOyB0aGVuCiAJCXNlZCAtaSAtZSAncyMke1dPUktESVJ9IyNnJyAk e0R9JHtsaWJkaXJ9L3B5dGhvbiovc2l0ZS1wYWNrYWdlcy9wZXJmLSovU09VUkNFUy50eHQKQEAg LTM4MCw3ICszODUsNyBAQCBQQUNLQUdFUyA9KyAiJHtQTn0tYXJjaGl2ZSAke1BOfS10ZXN0cyAk e1BOfS1wZXJsICR7UE59LXB5dGhvbiIKIAogUkRFUEVORFM6JHtQTn0gKz0gImVsZnV0aWxzIGJh c2giCiBSREVQRU5EUzoke1BOfS1hcmNoaXZlID0rICJiYXNoIgotUkRFUEVORFM6JHtQTn0tcHl0 aG9uID0rICJiYXNoIHB5dGhvbjMgcHl0aG9uMy1tb2R1bGVzICR7QGJiLnV0aWxzLmNvbnRhaW5z KCdQQUNLQUdFQ09ORklHJywgJ2F1ZGl0JywgJ2F1ZGl0LXB5dGhvbicsICcnLCBkKX0iCitSREVQ RU5EUzoke1BOfS1weXRob24gPSsgImJhc2ggcHl0aG9uMyBweXRob24zLW1vZHVsZXMgJHtAYmIu dXRpbHMuY29udGFpbnMoJ1BBQ0tBR0VDT05GSUcnLCAnc2NyaXB0aW5nIGF1ZGl0JywgJ2F1ZGl0 LXB5dGhvbicsICcnLCBkKX0iCiBSREVQRU5EUzoke1BOfS1wZXJsID0rICJiYXNoIHBlcmwgcGVy bC1tb2R1bGVzIgogUkRFUEVORFM6JHtQTn0tdGVzdHMgPSsgInB5dGhvbjMgYmFzaCIKIAo=
