commit c126ce2e705f45f5992442c0c8bf0dfe5b4f6919 Author: Chris Michael <[email protected]> Date: Wed Jan 18 11:29:14 2017 -0500 ecore-drm2: Add API function to set output rotation This patch adds a new API function that can be called from Enlightenment wl_drm module to enable output rotation. NB: Only works if Atomic support is enabled as it rotates the hardware plane directly...and we don't support planes without Atomic enabled. @feature Signed-off-by: Chris Michael <[email protected]> --- src/lib/ecore_drm2/Ecore_Drm2.h | 16 +++++++++++ src/lib/ecore_drm2/ecore_drm2_outputs.c | 49 +++++++++++++++++++++++++++++++++ 2 files changed, 65 insertions(+) diff --git a/src/lib/ecore_drm2/Ecore_Drm2.h b/src/lib/ecore_drm2/Ecore_Drm2.h index a7834c4..87d7b40 100644 --- a/src/lib/ecore_drm2/Ecore_Drm2.h +++ b/src/lib/ecore_drm2/Ecore_Drm2.h @@ -758,6 +758,22 @@ EAPI void ecore_drm2_output_gamma_set(Ecore_Drm2_Output *output, uint16_t size, EAPI int ecore_drm2_output_supported_rotations_get(Ecore_Drm2_Output *output); /** + * Set a rotation on a given output + * + * @param output + * @param rotation + * + * @return EINA_TRUE on success, EINA_FALSE otherwise + * + * @note This function will only work if Atomic support + * is enabled as it requires hardware plane support. + * + * @ingroup Ecore_Drm2_Output_Group + * @since 1.19 + */ +EAPI Eina_Bool ecore_drm2_output_rotation_set(Ecore_Drm2_Output *output, int rotation); + +/** * @defgroup Ecore_Drm2_Fb_Group Drm framebuffer functions * * Functions that deal with setup of framebuffers diff --git a/src/lib/ecore_drm2/ecore_drm2_outputs.c b/src/lib/ecore_drm2/ecore_drm2_outputs.c index 055b63d..a36c440 100644 --- a/src/lib/ecore_drm2/ecore_drm2_outputs.c +++ b/src/lib/ecore_drm2/ecore_drm2_outputs.c @@ -1529,3 +1529,52 @@ ecore_drm2_output_supported_rotations_get(Ecore_Drm2_Output *output) return ret; } + +EAPI Eina_Bool +ecore_drm2_output_rotation_set(Ecore_Drm2_Output *output, int rotation) +{ + Eina_Bool ret = EINA_FALSE; + + EINA_SAFETY_ON_NULL_RETURN_VAL(output, EINA_FALSE); + +#ifdef HAVE_ATOMIC_DRM + if (_ecore_drm2_use_atomic) + { + Ecore_Drm2_Plane_State *pstate; + drmModeAtomicReq *req = NULL; + int res = 0; + uint32_t flags = + DRM_MODE_ATOMIC_NONBLOCK | DRM_MODE_PAGE_FLIP_EVENT | + DRM_MODE_ATOMIC_ALLOW_MODESET; + + pstate = output->plane_state; + if ((pstate->supported_rotations & rotation) == 0) + { + WRN("Unsupported rotation"); + return EINA_FALSE; + } + + req = sym_drmModeAtomicAlloc(); + if (!req) return EINA_FALSE; + + sym_drmModeAtomicSetCursor(req, 0); + + res = sym_drmModeAtomicAddProperty(req, pstate->obj_id, + pstate->rotation.id, rotation); + if (res < 0) goto err; + + res = sym_drmModeAtomicCommit(output->fd, req, flags, output->user_data); + if (res < 0) goto err; + else + { + ret = EINA_TRUE; + pstate->rotation.value = rotation; + } + +err: + sym_drmModeAtomicFree(req); + } +#endif + + return ret; +} --
