No data on X-less Kabini APU (Athlon 5350) #27

Closed myxal closed 8 years ago

myxal commented 8 years ago

I tried the latest git master version on Ubuntu 14.04 (kernel 3.16, libdrm 2.4.60, fglrx-core 15.200) and I'm getting no data (all zeroes).

Is there a way to find out if this is a kernel/libdrm limitation, or a bug in radeontop?

clbr commented 8 years ago

Even on X, if nothing is going on, the GPU will be idle, and all fields will be zero (except VRAM, but that requires the open driver, you're on fglrx). Moving the mouse is not enough, I have to move a window around, scroll, or start a GL load to see numbers.

Did you have a workload going on? Just refreshing the same image at the console is not enough to create any measurable load.

Yeah, forgot to mention - the load is generated by Einstein@home's opencl_ati application.

Edit: Possibly also of note is that this machine is headless in both hardware and software configuration:

clbr commented 8 years ago

Please try the -m (--mem) option. Most of radeontop users are on the open driver, not a lot testing happens on the proprietary one.

myxal commented 8 years ago

Sorry for the late reply, the PSU in the machine died literally moments after my last reply :-\

The -m option works. (I was sure I tried it before without success, but it may have been with the old ubuntu-supplied version of radeontoop). Thanks.

I'm seeing ~90% usage on Graphics Pipe, Texture Addresser and Shader Interpolator, all others are 0.

clbr commented 8 years ago

Yes, many of the blocks are graphics-specific, so a CL load wouldn't use them. Closing.
