From: Varad Gautam <varad.gau...@collabora.com> allow creating EGLImages with dmabuf format modifiers when target is EGL_LINUX_DMA_BUF_EXT for EGL_EXT_image_dma_buf_import_modifiers.
v2: - clear modifier assembling and error label name (Eric Engestrom) v3: - remove goto jumps within switch-case (Emil Velikov) - treat zero as valid modifier (Daniel Stone) - ensure same modifier across all dmabuf planes (Emil Velikov) Signed-off-by: Pekka Paalanen <pekka.paala...@collabora.co.uk> Signed-off-by: Varad Gautam <varad.gau...@collabora.com> Reviewed-by: Eric Engestrom <eric.engest...@imgtec.com> --- src/egl/drivers/dri2/egl_dri2.c | 79 +++++++++++++++++++++++++++++++++++------ src/egl/main/eglimage.c | 48 +++++++++++++++++++++++++ src/egl/main/eglimage.h | 2 ++ 3 files changed, 118 insertions(+), 11 deletions(-) diff --git a/src/egl/drivers/dri2/egl_dri2.c b/src/egl/drivers/dri2/egl_dri2.c index ceffd28..9139bd4 100644 --- a/src/egl/drivers/dri2/egl_dri2.c +++ b/src/egl/drivers/dri2/egl_dri2.c @@ -1949,6 +1949,33 @@ dri2_check_dma_buf_attribs(const _EGLImageAttribs *attrs) } } + /** + * If <target> is EGL_LINUX_DMA_BUF_EXT, both or neither of the following + * attribute values may be given. + * + * This is referring to EGL_DMA_BUF_PLANE0_MODIFIER_LO_EXT and + * EGL_DMA_BUF_PLANE0_MODIFIER_HI_EXT, and the same for other planes. + */ + for (i = 0;
