Author: Varad Gautam <varadgau...@gmail.com> Date: Tue May 30 17:41:36 2017 +0530 dri: introduce dmabuf format modifier related handles these allow dmabuf import with modifiers, and supported format and modifier queries, which are used to implement EGL_EXT_image_dma_buf_import_modifiers. v2: - squash dmabuf queries into DRIimage version 15 (Jason Ekstrand). - add external_only param to queryDmaBufModifiers (Emil, Daniel Stone) - pass a single modifier form createImageFromDmaBufs2 since all planes have the same modifier (Jason Ekstrand) Signed-off-by: Pekka Paalanen <pekka.paala...@collabora.co.uk> Signed-off-by: Varad Gautam <varad.gau...@collabora.com> Reviewed-by: Daniel Stone <dani...@collabora.com> Reviewed-by: Emil Velikov <emil.veli...@collabora.com> Reviewed-by: Eric Engestrom <eric.engest...@imgtec.com> --- include/GL/internal/dri_interface.h | 63 ++++++++++++++++++++++++++++++++++++- 1 file changed, 62 insertions(+), 1 deletion(-) diff --git a/include/GL/internal/dri_interface.h b/include/GL/internal/dri_interface.h index ffe99499fc..fc2d4bbe22 100644 --- a/include/GL/internal/dri_interface.h +++ b/include/GL/internal/dri_interface.h @@ -1137,7 +1137,7 @@ struct __DRIdri2ExtensionRec { * extensions. */ #define __DRI_IMAGE "DRI_IMAGE" -#define __DRI_IMAGE_VERSION 14 +#define __DRI_IMAGE_VERSION 15 /** * These formats correspond to the similarly named MESA_FORMAT_* @@ -1494,6 +1494,67 @@ struct __DRIimageExtensionRec { const uint64_t *modifiers, const unsigned int modifier_count, void *loaderPrivate); + + /* + * Like createImageFromDmaBufs, but takes also format modifiers. + * + * For EGL_EXT_image_dma_buf_import_modifiers. + * + * \since 15 + */ + __DRIimage *(*createImageFromDmaBufs2)(__DRIscreen *screen, + int width, int height, int fourcc, + uint64_t modifier, + int *fds, int num_fds, + int *strides, int *offsets, + enum __DRIYUVColorSpace color_space, + enum __DRISampleRange sample_range, + enum __DRIChromaSiting horiz_siting, + enum __DRIChromaSiting vert_siting, + unsigned *error, + void *loaderPrivate); + + /* + * dmabuf format query to support EGL_EXT_image_dma_buf_import_modifiers. + * + * \param max Maximum number of formats that can be accomodated into + * \param formats.
