899fbde1464639e3d12eaffdad8481a59b367fcb is the first bad commit commit 899fbde1464639e3d12eaffdad8481a59b367fcb Author: Philip Yang Date: Thu Dec 13 15:35:28 2018 -0500 drm/amdgpu: replace get_user_pages with HMM mirror helpers Use HMM helper function hmm_vma_fault() to get physical pages backing userptr and start CPU page table update track of those pages. Then use hmm_vma_range_done() to check if those pages are updated before amdgpu_cs_submit for gfx or before user queues are resumed for kfd. If userptr pages are updated, for gfx, amdgpu_cs_ioctl will restart from scratch, for kfd, restore worker is rescheduled to retry. HMM simplify the CPU page table concurrent update check, so remove guptasklock, mmu_invalidations, last_set_pages fields from amdgpu_ttm_tt struct. HMM does not pin the page (increase page ref count), so remove related operations like release_pages(), put_page(), mark_page_dirty().

[Kernel-packages] [Bug 1844962] Re: apparent memory usage regression - not getting freed?
** Attachment added: ""bad" memory usage" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1844962/+attachment/5290532/+files/Screenshot%20from%202019-09-22%2021-24-40.png -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1844962 Title: apparent memory usage regression - not getting freed? Status in linux package in Ubuntu: New Bug description: In eoan on a 5.3 kernel, have noticed a few incidents of the system becoming sluggish/unresponsive, which appears to be caused by low available memory. top is reporting 13 of 16G are "used", but adding up the memory reported by top sorted by memory usage appears like it should be closer to 3-4G "used". Attaching two top screenshots, one shows 3.3G used and system behaving well, the other shows 14G used and system lagging. In both cases, approximately the same programs are being run taking up approximately the same amount of resident memory, so not sure where all the memory usage is coming from.
