Subject: [PATCH] ath11k: disable unused CE8 interrupts for ipq8074
|
|
|
|
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.
