More than that, it's known *not* to be properly supported on one such applicable device: Subject: [RFC] qcom_scm: IPQ4019 firmware does not support atomic API? https://lore.kernel.org/linux-arm-kernel/20200913201608.GA3162100@bDebian/ I still haven't gotten a solution to *that* problem upstream, but it'd be nice not to make it worse.
