We can't really enumerate all supported cursor sizes on the platforms where the cursor height can vary freely, so for simplicity we'll just expose all square+POT sizes between each platform's min and max cursor limits. Depending on the platform this will give us one of three results: - 64x64,128x128,256x256,512x512 - 64x64,128x128,256x256 - 64x64 Cc: Simon Ser Cc: Jonas Ådahl Cc: Daniel Stone Cc: Pekka Paalanen Signed-off-by: Ville Syrjälä --- drivers/gpu/drm/i915/display/intel_cursor.c | 24 +++++++++++++++++++++ 1 file changed, 24 insertions(+) diff --git a/drivers/gpu/drm/i915/display/intel_cursor.c b/drivers/gpu/drm/i915/display/intel_cursor.c index c3173c0c2068..cb6cf3009727 100644 --- a/drivers/gpu/drm/i915/display/intel_cursor.c +++ b/drivers/gpu/drm/i915/display/intel_cursor.c @@ -757,6 +757,28 @@ static const struct drm_plane_funcs intel_cursor_plane_funcs = { .format_mod_supported = intel_cursor_format_mod_supported, }; +static void intel_cursor_add_size_hints_property(struct intel_plane *plane) +{ + struct drm_i915_private *i915 = to_i915(plane->base.dev); + const struct drm_mode_config *config = &i915->drm.mode_config; + struct drm_plane_size_hint hints[4]; + int size, max_size, num_hints = 0; + + max_size = min(config->cursor_width, config->cursor_height); + + /* for simplicity only enumerate the supported square+POT sizes */ + for (size = 64; size <= max_size; size *= 2) { + if (drm_WARN_ON(&i915->drm, num_hints >= ARRAY_SIZE(hints))) + break; + + hints[num_hints].width = size; + hints[num_hints].height = size; + num_hints++; + } + + drm_plane_add_size_hints_property(&plane->base, hints, num_hints); +} + struct intel_plane * intel_cursor_plane_create(struct drm_i915_private *dev_priv, enum pipe pipe) @@ -815,6 +837,8 @@ intel_cursor_plane_create(struct drm_i915_private *dev_priv, DRM_MODE_ROTATE_0 | DRM_MODE_ROTATE_180); + intel_cursor_add_size_hints_property(cursor); + zpos = RUNTIME_INFO(dev_priv)->num_sprites[pipe] + 1; drm_plane_create_zpos_immutable_property(&cursor->base, zpos);
