Subject: [PATCH v3 01/12] ath11k: disable unused CE8 interrupts for ipq8074
Date: Thu,  2 Sep 2021 11:03:29 +0530	[thread overview]
Message-ID: <1630560820-21905-2-git-send-email-ppranees@codeaurora.org> (raw)
In-Reply-To: <1630560820-21905-1-git-send-email-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
