Hi,
I have a GPU application running on the GC7000L GPU of the iMX8M Quad Processor.
When I profile the kernels for execution time, I get different results during different executions. I suspect, the clock frequency is varying during each instance.
So, could you please share info regarding how to set the clock frequency of the GC7000L GPU on the iMX8M Quad EVK board?
Please point me to the appropriate documentation which describes the clock setting of GC7000L GPU.
Note: the OS on the board is the Linux BSP package distributed by NXP: version L4.9.88_2.0.0
Thanks and regards
Vinay
Hi Vinay
available clock options can be found in driver sources:
linux/drivers/clk/imx/clk-imx8mq.c
clk-imx8mq.c\imx\clk\drivers - linux-imx - i.MX Linux kernel
dts file
fsl-imx8mq.dtsi\freescale\dts\boot\arm64\arch - linux-imx - i.MX Linux kernel
Linux common clock framework documentation
