Subject: [PATCH 00/18] Add perf support to the rockchip-dfi driver
Date: Fri, 3 Feb 2023 13:49:54 +0100 [thread overview]
Message-ID: <20230203125012.3804008-1-s.hauer@pengutronix.de> (raw)
This series adds perf support to the Rockchip DFI driver.
The DFI is a unit for measuring DRAM performance. Its driver is
currently located under drivers/devfreq/event/ as it serves as an event
driver for DRAM frequency scaling. With this series it can also be used
as a perf driver for measuring DRAM throughput. Usage looks like:
perf stat -a -e rockchip_ddr/cycles/,\
rockchip_ddr/read-bytes/,\
rockchip_ddr/write-bytes/,\
rockchip_ddr/bytes/ sleep 1
Performance counter stats for 'system wide':
1582524826 rockchip_ddr/cycles/
1802.25 MB rockchip_ddr/read-bytes/
1793.72 MB rockchip_ddr/write-bytes/
3595.90 MB rockchip_ddr/bytes/
1.014369709 seconds time elapsed
My target SoC is RK3568 which is not yet supported by the driver, so the
series starts with some cleanups and preparations, then RK3568 support
is added and finally perf support.
The driver is tested on both a RK3568 board and a RK3399 board, the
latter with dual channel memory. The measured values look sane,
read-bytes plus write-bytes is equal to totally transferred bytes, the
values reported by perf are slightly higher than the values my copy
from/to RAM test tool reports, as expected.
