Hi,
Static analysis with Coverity has detected a division by zero in the
following commit:
commit 5b5abe9526073ccbf3032d27b5864520829cdd9c

drm/amd/display: make PSR static screen entry within 30 ms
Specifically:
unsigned int vsync_rate_hz = 0;
struct dc_static_screen_params params = {0};
/* Calculate number of static frames before generating interrupt to
* enter PSR.
*/
unsigned int frame_time_microsec = 1000000 / vsync_rate_hz;
vsync_rate_hz is zero, and frame_time_microsec is being assigned a value
that is being divided by zero. I'm not sure why this is coded this way
and not sure what the fix is, hence I'm reporting the issue.
Colin
