Subject: [PATCH 0/2] Let userspace know about swapped out panthor GEM objects
Date: Mon, 20 Apr 2026 17:46:58 +0200 [thread overview]
Message-ID: <20260420-panthor-bo-reclaim-observability-v1-0-a4d1a36ee84f@collabora.com> (raw)
Panthor has recently gained a GEM shrinker. It allows evicting memory
that backs unused GEM objects to swap.
In this series, both fdinfo and Panthor's gems debugfs are extended so
that information on evicted pages can be gathered by users through these
two methods.
