This provides\nimmediate relief under heavy memory pressure instead of waiting for victim\nprocesses to naturally release their memory.\n\nUtilize the OOM reaper by creating another kthread in Simple LMK to perform\nvictim reaping. Similar to the OOM reaper kthread (which is unused with\nSimple LMK), this new kthread allows reaping to race with exit_mmap() in\norder to preclude the need to take a reference to an mm's address space and\nthus potentially mmput() an mm's last reference. Doing so would stall the\nreaper kthread, preventing it from being able to quickly reap new victims.\n\nReaping is done on victims one at a time by descending order of anonymous\npages, so that the most promising victims with the most anonymous pages\nare reaped first. Victims are also marked for reaping via MMF_OOM_VICTIM so\nthat they reap themselves first in exit_mmap(). Even if a victim isn't\nreaped by the reaper thread, it'll free its anonymous memory first thing in\nexit_mmap() as a small win towards making memory available sooner.\n\nBy relieving memory pressure faster via reaping, Simple LMK not only\ndoesn't need to kill as many processes, but also improves system\nresponsiveness when memory is low since memory pressure is relieved sooner.\n\nAlthough not strictly required, Simple LMK should be the only one utilizing\nthe OOM reaper. Any other code that may utilize the OOM reaper, such as\npatches that invoke the OOM reaper for all SIGKILLs, should be disabled.\n\nSigned-off-by: Sultan Alsawaf \nSigned-off-by: Panchajanya1999 ","shortMessageHtmlLink":"simple_lmk: Reap anonymous memory from victims"}},{"before":"01ab16a097f83636c5d8d6781cde1e0106f5d353","after":"e8b455f0b5bc808c3fd97812afd2cc0346bae889","ref":"refs/heads/R","pushedAt":"2023-05-06T14:15:39.000Z","pushType":"push","commitsCount":2,"pusher":{"login":"Panchajanya1999","name":"panchajanya.","path":"/Panchajanya1999","primaryAvatarUrl":"https://github.com/avatars/u/26135639?s=80&v=4"},"commit":{"message":"simple_lmk: Fix victim scheduling priority elevation\n\nAs it turns out, victim scheduling priority elevation has always been\nbroken for two reasons:\n1. The minimum valid RT priority is 1, not 0. As a result,\n sched_setscheduler_nocheck() always fails with -EINVAL.\n2. The thread within a victim thread group which happens to hold the mm is\n not necessarily the only thread with references to the mm, and isn't\n necessarily the thread which will release the final mm reference. As a\n result, victim threads which hold mm references may take a while to\n release them, and the unlucky thread which puts the final mm reference\n may take a very long time to release all memory if it doesn't have RT\n scheduling priority.\n\nThese issues cause victims to often take a very long time to release their\nmemory, possibly up to several seconds depending on system load. This, in\nturn, causes Simple LMK to constantly hit the reclaim timeout and kill more\nprocesses, with Simple LMK being rather ineffective since victims may not\nrelease any memory for several seconds.\n\nFix the broken scheduling priority elevation by changing the RT priority to\nthe valid lowest priority of 1 and applying it to all threads in the thread\ngroup, instead of just the thread which holds the mm.\n\nSigned-off-by: Sultan Alsawaf \nSigned-off-by: Panchajanya1999 ","shortMessageHtmlLink":"simple_lmk: Fix victim scheduling priority elevation"}}],"hasNextPage":false,"hasPreviousPage":false,"activityType":"all","actor":null,"timePeriod":"all","sort":"DESC","perPage":30,"cursor":"Y3Vyc29yOnYyOpK7MjAyNC0wMy0yMVQwODo0MzowOS4wMDAwMDBazwAAAAQbfv9F","startCursor":"Y3Vyc29yOnYyOpK7MjAyNC0wMy0yMVQwODo0MzowOS4wMDAwMDBazwAAAAQbfv9F","endCursor":"Y3Vyc29yOnYyOpK7MjAyMy0wNS0wNlQxNDoxNTozOS4wMDAwMDBazwAAAAMnYJpG"}},"title":"Activity ยท Panchajanya1999/msm-4.14"}
