From ffc6a094b47b33c5bc734ed9d2638d7242013c0d Mon Sep 17 00:00:00 2001 From: Nirav Shah Date: Thu, 9 Jun 2016 16:09:08 +0530 Subject: [PATCH] qcacld-3.0: Vote performance qos for high throughput use case With WLAN use case, FPC(Fast Power Collapse) wakeup latency is too long. Then some use case, FPC feature break performance. To ensure CPU wakeup, if detected high throughput, vote for performance qos not to activate FPC.
