[AMD Official Use Only]

Hi Michel,

After the system idle for a while, the screen will be off(blank out) and AMD GPU will be put into a very low power state(BACO) due to runpm.
However, I found there will be still DRM IOCTLS(which I paste below) coming regularly.
And those IOCTLS(especially those for AMDGPU) will wake and back our GPU into normal state.
To me, that's a little weird as the system was just left there for nothing. I do not know what and why these DRM IOCTLs come for.
Per Alex, it seems "desktop environments poll for display updates at regular intervals". Do you also think so? Or any other insights?

Good morning,

for the background I advised to contact you Michel since we couldn't 
find an explanation.

Alex explanation might be correct, but the CS seems to come from the X 
server and is always roughly 60 seconds after going into power save.

Any idea what that could be?

Thanks,
Christian.

For the DRM_IOCTL_MODE_* ioctls, attaching gdb to Xorg and setting a breakpoint on drmIoctl should show where they're coming from.

The AMDGPU_CS ioctls are probably from glamor calling OpenGL, most likely for X11 drawing protocol requests. Note that in this case drmIoctl/ioctl will likely be called from a separate thread. Pierre / Marek should be able to help you find out where the OpenGL calls are coming from.


In general, Xorg only ever does anything in response to:

* X11 protocol requests, i.e. on behalf of clients.
* Input events, i.e. on behalf of the user.
* Other kernel events, e.g. hotplug events.


FWIW, with only xfwm4 & xterm running on Xorg, I'm not seeing any drmIoctl calls during DPMS off. So the ioctls you're seeing are most likely triggered by clients.

Hi,

Printing the backtrace from si_flush_gfx_cs while /etc/environment contains
GALLIUM_THREAD=0 at boot should show which GL call and X call caused the
flush.

That will most likely be glFlush in (_)glamor_block_handler, or maybe in glamor_sync_fence_set_triggered. 

The former do not get called directly from the X11 request handler which triggers the drawing. I suggest e.g. st_draw_gallium instead.
