Subject: [PATCH] drm/panthor: clean up some types in panthor_sched_suspend()
Date: Mon, 8 Apr 2024 10:36:35 +0300 [thread overview]
Message-ID: <85356b15-4840-4e64-8c75-922cdd6a5fef@moroto.mountain> (raw)
These variables should be u32 instead of u64 because they're only
storing u32 values. Also static checkers complain when we do:
suspended_slots &= ~upd_ctx.timedout_mask;
In this code "suspended_slots" is a u64 and "upd_ctx.timedout_mask". The
mask clears out the top 32 bits which would likely be a bug if anything
were stored there.
