Pull request overview
This PR updates CachyOS kernel configuration defaults for transparent hugepages (THP) on shmem/tmpfs to use the ADVISE mode, aligning with upstream behavior and addressing the reported Steam Overlay choppiness regression (issue #874) introduced by upstream’s “shmem/tmpfs hugepage defaults config choice” change.
Changes:
- Switch shmem THP default from
WITHIN_SIZEtoADVISEacross kernel config variants. - Switch tmpfs THP default from
WITHIN_SIZE(orNEVERin hardened) toADVISEacross kernel config variants.
