nohang le9 patch その他 "le9" Strives To Make Linux Very Usable On Systems With Small Amounts Of RAM - Phoronix https://github.com/hakavlad/nohang#solution 7 / 28
hakavlad/nohang: A sophisticated low memory handler for Linux GitHub - hakavlad/le9-patch: [PATCH] mm: Protect clean file pages under memory pressure to prevent thrashing, avoid high latency and prevent livelock in near-OOM conditions 8 / 28
amount of memory Amount of memory to be used in cases as follows: 1 for test; 2 when the kernel is not able to see the whole system memor 3 memory that lies after 'mem=' boundary is excluded from the hypervisor, then assigned to KVM guests. [X86] Work as limiting max address. Use together with memmap= to avoid physical address space collisions. Without memmap= PCI devices could be placed at addresses belonging to unused RAM. Note that this only takes effects during boot time since in above case 3, memory may need be hot added after boot if system memory of hypervisor is not sufficient. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/Documentation/ad guide/kernel-parameters.txt?h=v5.13.3#n2724 22 / 28
