For larger stuff (and imo this is right above the cutoff) you first need to add the new functions/defines, then convert everyone over. And only when all the drivers are converted can we apply the patch to remove the old functions/defines. -Daniel > --- > include/drm/drm_dp_helper.h | 16 ++++++++-------- > 1 file changed, 8 insertions(+), 8 deletions(-) > > diff --git a/include/drm/drm_dp_helper.h b/include/drm/drm_dp_helper.h > index a21568b..70f362b 100644 > --- a/include/drm/drm_dp_helper.h > +++ b/include/drm/drm_dp_helper.h > @@ -190,16 +190,16 @@ > # define DP_TRAIN_VOLTAGE_SWING_MASK 0x3 > # define DP_TRAIN_VOLTAGE_SWING_SHIFT 0 > # define DP_TRAIN_MAX_SWING_REACHED (1 << 2) > -# define DP_TRAIN_VOLTAGE_SWING_400 (0 << 0) > -# define DP_TRAIN_VOLTAGE_SWING_600 (1 << 0) > -# define DP_TRAIN_VOLTAGE_SWING_800 (2 << 0) > -# define DP_TRAIN_VOLTAGE_SWING_1200 (3 << 0) > +# define DP_TRAIN_VOLTAGE_SWING_LEVEL_0 (0 << 0) > +# define DP_TRAIN_VOLTAGE_SWING_LEVEL_1 (1 << 0) > +# define DP_TRAIN_VOLTAGE_SWING_LEVEL_2 (2 << 0) > +# define DP_TRAIN_VOLTAGE_SWING_LEVEL_3 (3 << 0) > > # define DP_TRAIN_PRE_EMPHASIS_MASK (3 << 3) > -# define DP_TRAIN_PRE_EMPHASIS_0 (0 << 3) > -# define DP_TRAIN_PRE_EMPHASIS_3_5 (1 << 3) > -# define DP_TRAIN_PRE_EMPHASIS_6 (2 << 3) > -# define DP_TRAIN_PRE_EMPHASIS_9_5 (3 << 3) > +# define DP_TRAIN_PRE_EMPHASIS_LEVEL_0 (0 << 3) > +# define DP_TRAIN_PRE_EMPHASIS_LEVEL_1 (1 << 3) > +# define DP_TRAIN_PRE_EMPHASIS_LEVEL_2 (2 << 3) > +# define DP_TRAIN_PRE_EMPHASIS_LEVEL_3 (3 << 3) > > # define DP_TRAIN_PRE_EMPHASIS_SHIFT 3 > # define DP_TRAIN_MAX_PRE_EMPHASIS_REACHED (1 << 5) > -- > 1.7.10.4 > > _______________________________________________ > Intel-gfx mailing list > Intel-gfx@lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/intel-gfx

Btw for the actual replacement I highly recommend to do it with a semantic patch and cocci. There's unfortunately not a hole lot of good documentation around, but we recently started and it helps a lot with regenerating patches (e.g. for newly merged drm drivers) and avoiding mistakes for manual conversions. If we do a cocci patch we put it into the commit message, grep for @@. -Daniel

(+cc Daniel Vetter) Hi Sonika Jindal, Thank you for sending the patch. However, please add the reason to this commit message, as you said at '[PATCH 0/6] Rename DP training vswing/pre-emph defines'.
