Hi, Here's an update on the EGL/DRM integration extensions and patches. I've updated the patches with the feedback from the discussions on the list to the extent that I think is feasible. I think we're pretty close to consensus on how to do this, but let me know what you think. There's also a new extension in the series, the EGL_INTEL_no_surface extension, which lets us make a context current without a surface.
I updated the eglkms.c test case, and it now compiles and runs against this patch series: http://cgit.freedesktop.org/~krh/mesa-demos/tree/src/egl/opengl/eglkms.c [PATCH 1/6] egl: Add MESA_typed_display infrastructure This is the updated version of the alternative eglGetDisplay extension. I've incorporated the feedback from Chia-I regarding naming of the entry point and tokens, and Jakobs suggestion that we add tokens for the existing platforms (Win32 and X11). It's still a new entrypoint, not separate .so's as Chia-I suggested. I don't think it's a terrible idea to have separate .so's with different names, but I still like this better, and with separate .so's we'll have to compile libEGL several times to output the different libraries, which is awkward and a pain for distributions. I dropped the XCB display for now. [PATCH 2/6] egl_dri2: Support EGL_DISPLAY_TYPE_DRM_MESA This one just adds support to egl_dri2, should be pretty harmless. [PATCH 3/6] egl: EGL_INTEL_no_surface extension The new extension mentioned above. It adds a new config attribute to inidicate the APIs that support making a context current with that config and no surfaces. Previous discussion on this have stalled on the problem that not all client APIs have a meaningful way to make a context current without surfaces. By specifying the supported APIs in the config we solve this problem. See the spec in the patch for details. [PATCH 4/6] egl: MESA_image_drm extension This is the extension to create drm images from nothing using eglCreateDRMImageMESA, share them using eglShareDRMImageMesa, and import them using the EGL_DRM_BUFFER_MESA target with eglCreateImageKHR. Sharing an image is a separate entrypoint because a drm buffer doesn't necesarily have a global name and creating one is an extra step that we don't always want to incur. [PATCH 5/6] egl_dri2: Add support for MESA_image_drm Nothing to see here, just the implementation. Some of the attrib_list checking could be lifted to egl/main. [PATCH 6/6] intel: Add support for MESA_drm_image The intel dri driver side of things.
