Subject: [PATCH v2 03/11] rtw88: coex: add write scoreboard action when WLAN in critical procedure
Date: Thu, 12 Nov 2020 11:14:22 +0800	[thread overview]
Message-ID: <20201112031430.4846-4-pkshih@realtek.com> (raw)
In-Reply-To: <20201112031430.4846-1-pkshih@realtek.com>

From: Ching-Te Ku <ku920601@realtek.com>

When WLAN in critical procedure, such as connecting, scan and so on,
coexistence will notify BT by scoreboard.
While BT firmware received the scoreboard interrupt, it will adjust
BT page priority lower to avoid WLAN critical procedure suffering impact.
