So that bridge drivers have a way to check/reject an atomic operation. The drm_atomic_bridge_chain_check() (which is just a wrapper around the ->atomic_check() hook) is called in place of drm_bridge_chain_mode_fixup() (when ->atomic_check() is not implemented, the core falls back on ->mode_fixup(), so the behavior should stay the same for existing bridge drivers). v10: * Add changelog to the commit message v8 -> v9: * No changes v7: * Fix a NULL pointer dereference v5 -> v6: * No changes v4: * Add R-bs v3: * No changes v2: * Clarify the fact that ->atomic_check() is replacing ->mode_fixup() Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Reviewed by: Jernej Skrabec <jernej.skrabec@siol.net> Tested-by: Jonas Karlman <jonas@kwiboo.se> Link: https://patchwork.freedesktop.org/patch/msgid/20200128135514.108171-6-boris.brezillon@collabora.com |
