From: <yhchuang@realtek.com> To: <kvalo@codeaurora.org> Cc: <linux-wireless@vger.kernel.org>, <briannorris@chromium.org> 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.
