Might also want to give a link to the actual build failure, and give credit to the reporter: Closes: https://lore.kernel.org/r/20240619154207.GA1125704@thelio-3990X Reported-by: Nathan Chancellor <nat...@kernel.org> > > Fixes: 1676ecd303ac ("drm/i915: Compute CMRR and calculate vtotal") > Cc: Mitul Golani <mitulkumar.ajitkumar.gol...@intel.com> > Cc: Ankit Nautiyal <ankit.k.nauti...@intel.com> > Cc: Suraj Kandpal <suraj.kand...@intel.com> > Cc: Jani Nikula <jani.nik...@linux.intel.com> > Cc: Rodrigo Vivi <rodrigo.v...@intel.com> > Cc: Nathan Chancellor <nat...@kernel.org> > Cc: intel...@lists.freedesktop.org > Signed-off-by: Mitul Golani <mitulkumar.ajitkumar.gol...@intel.com> > --- > drivers/gpu/drm/i915/display/intel_vrr.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/drivers/gpu/drm/i915/display/intel_vrr.c > b/drivers/gpu/drm/i915/display/intel_vrr.c > index 6430da25957d..5a0da64c7db3 100644 > --- a/drivers/gpu/drm/i915/display/intel_vrr.c > +++ b/drivers/gpu/drm/i915/display/intel_vrr.c > @@ -137,7 +137,7 @@ static unsigned int > cmrr_get_vtotal(struct intel_crtc_state *crtc_state, bool > video_mode_required) > { > int multiplier_m = 1, multiplier_n = 1, vtotal, desired_refresh_rate; > - long long adjusted_pixel_rate; > + u64 adjusted_pixel_rate; > struct drm_display_mode *adjusted_mode = &crtc_state->hw.adjusted_mode; > > desired_refresh_rate = drm_mode_vrefresh(adjusted_mode); -- Jani Nikula, Intel
