Created attachment 128481 [details] [review] Setting correct core and memory clock for M370X in MBP 11,5

No screen flickering after testing out this patch I made on the v4.9 branch. I confirmed the GPU configuration on this page https://en.wikipedia.org/wiki/AMD_Radeon_Rx_300_series. Set mclk and sclk accordingly; assuming that mclk is for memory and sclk is for the GPU clock.

Noticeably everything is running very nicely. No strange behaviour so far and both GPU and CPU temps are OK.

In addition. My CPU turbo boost is also working, which it previously wasn't on 3.8.6. Test at your own risk.

hi berg, thanks for your attachment. I am new to linux kernel, and I don't how to apply your attachment, i.e. how to compile a single radeon.ko ? I find a radeon.ko under "/lib/modules/4.8.0-36-generic/kernel/drivers/gpu/drm/radeon", so I want to compile it, likes here: https://bugzilla.kernel.org/show_bug.cgi?id=105051#c37

I modify si_dpm.c and write a Makefile: obj-m += si_dpm.o

all: make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

clean: make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

but when make I get: /si_dpm.c:24:18: fatal error: drmP.h: No such file or directory compilation terminated.

so could you tell me how to compile a single .ko or if any tutorial I can follow, or I have to compile all the kernel?

thanks!
