From 1da06864391458119686e19796fdcec9a59dce55 Mon Sep 17 00:00:00 2001 From: Jake Weinstein Date: Wed, 13 Jan 2021 06:16:22 +0100 Subject: [PATCH] fingerprint: Revert "fpc: keep fpc in system-background" While Google found that fingerprint HAL is insensitive to increased CPU throughput, we have not found that to be the case. Allowing more CPUs makes fingerprint unlock up to 2x faster in some tests.
