Subject: [PATCH v2 3/8] rtw88: 8822c: Enable interrupt migration
Date: Mon, 9 Sep 2019 15:16:06 +0800
Message-ID: <1568013371-21805-4-git-send-email-yhchuang@realtek.com> (raw)
In-Reply-To: <1568013371-21805-1-git-send-email-yhchuang@realtek.com>

From: Tsang-Shian Lin <thlin@realtek.com>

Enable 8822C Tx/Rx interrupt migration.
In some platforms, performance test may cause heavy cpu loading and get
bad results. Interrupt migration can decrease the amount of interrupts,
and lower cpu loading.
