Subject: [PATCH 01/12] ath11k: disable unused CE8 interrupts for ipq8074
Date: Wed, 16 Jun 2021 00:13:56 +0300 [thread overview]
Message-ID: <20210615211407.92233-2-jouni@codeaurora.org> (raw)
In-Reply-To: <20210615211407.92233-1-jouni@codeaurora.org>
From: P Praneesh <ppranees@codeaurora.org>
Host driver doesn't need to process CE8 interrupts (used
by target independently)
The volume of interrupts is huge within short interval,
CPU0 CPU1 CPU2 CPU3
14022188 0 0 0 GIC 71 Edge ce8
Hence disabling unused CE8 interrupt will improve CPU usage.
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1.r2-00012-QCAHKSWPL_SILICONZ-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-01695-QCAHKSWPL_SILICONZ-1
