Subject: Question: the status for SMMUv2 PMU driver
Date: Fri, 22 Oct 2021 18:55:17 +0800 [thread overview]
Message-ID: <20211022105517.GE213960@leoy-ThinkPad-X240s> (raw)
Hi Will, Robin,
[ + Arm mailing list ]
Linux mainline kernel has supported SMMUv3 PMU with the driver
drivers/perf/arm_smmuv3_pmu.c, but it misses to support SMMUv2 PMU
driver.
So I want to confirm if there have any existed SMMUv2 PMU driver
can be referred, or if any block issue for upstreaming SMMUv2
driver? Thank you for suggestions and insights.
Leo
