https://bugs.freedesktop.org/show_bug.cgi?id=83881 --- Comment #13 from Pekka Paalanen --- With Daniel Vetter's and Carlos Olmedo Escobar's comments addressed, v3 (a trivial rebase) of this series is now pushed to Weston: f3c8336..5386898 master -> master We can continue testing, developing, and changing the dmabuf protocol in Weston until we are happy with it. I wonder if we should leave this bug open until the protocol is deemed stable, or should we close it now? -- You are receiving this mail because: You are the assignee for the bug. ___ wayland-bugs mailing list wayland-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/wayland-bugs

https://bugs.freedesktop.org/show_bug.cgi?id=83881 --- Comment #11 from Pekka Paalanen --- Okay, since Phab is so nice for reviewing things (though less nice for submitting things for now), there is a new revision of patches attached to http://phabricator.freedesktop.org/T13 Feel free to have a look and leave comments. I will address them and then do a submission to wayland-devel@ the old way which will become the RFCv2 series, or preferably just v2 series for landing in Weston. This is also available in https://git.collabora.com/cgit/user/pq/weston.git/log/?h=dmabuf-WIP (Note: dmabuf-WIP branch will get rewritten when I update the series.) -- You are receiving this mail because: You are the assignee for the bug. ___ wayland-bugs mailing list wayland-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/wayland-bugs

It is still in evaluation, testing and drive-in phase, where a limited set of people work on it. We are trying to establish proper work flows before announcing it for public evaluation. Until then, I think we should keep this fd.o bug as the primary place. Once we've done our own reviews in Phab (which is public, just not announced), we'll send the series to wayland-devel@ as usual and note it here. Sorry for the confusion. :-) Still, feel free to poke around Phab and see what it has. -- You are receiving this mail because: You are the assignee for the bug. ___ wayland-bugs mailing list wayland-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/wayland-bugs

https://bugs.freedesktop.org/show_bug.cgi?id=83881 --- Comment #8 from Nicolas Dufresne --- (In reply to Benjamin Gaignard from comment #6) > Which GStreamer video sink do you use as client ? > How do you allocate the buffers in this sink ? The GStreamer part should probably be discussed here. https://bugzilla.gnome.org/show_bug.cgi?id=711155 I'll try to comment base on what should concern wayland, adding a little context. In GStreamer there will is two possible display element working on Wayland, glimagesink and waylandsink. glimagesink uses client side EGL/OpenGL/GLES2 to render the video. It will most likely never allocated DMABUF, but will most likely be able to import them. This can already be implemented without any changes to current Wayland protocols. waylansink, uses wayland specific representation for wrapping video memory. It's a smarter choice, since it gives the compositor the choices of the smartest renderer. Adding DMABUF in this case requires protocols. The patches submitted at the beginning of the year were not merged because of open issues, including usage of driver specific APIs and that this new protocol was still changing very quickly. What has been proposed to Benjamin was to focus on getting importation of DMABUF first, and come back with allocation when this problem get resolved in a better way. The allocation of DMABUF remains an open issue for everyone. A small comment though, if we want this work to be usable in waylansink. By it's nature, the alignment of a DMABUF frame received might not match the required alignment by the GPU or HW mixer, or any HW involved. A miss-match should never prevent the rendering of a buffer unless the buffer is not mappable to user space. This is often not so simple as only kernel space can figure-out there is a miss-match (at least at the moment). It is important to handle this nicely and manage non-destructive fallback. -- You are receiving this mail because: You are the assignee for the bug. ___ wayland-bugs mailing list wayland-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/wayland-bugs

The namespace is different, and we don't really have a good place for global constants in Wayland. I suppose one could re-use the wl_shm format list... or just pick formats from drm_fourcc.h directly, since I believe these are meant to be identical. The thing with wl_shm is that it is not limited to systems with dmabuf, while I think all dmabuf systems already have drm_fourcc.h. > simple-dmabuf.c use intel specific functions for buffer management, could > you make it more generic by using only standard libdrm function ? If GBM offers it, sure. It just means that simple-dmabuf will depend on Mesa basically, and probably even need to use GL to fill the buffer. Or maybe some V4L device could create and export dmabufs. > You make linux_dmabuf works for gl-renderer what about pixman-renderer ? Pixman renderer would require mmap() support which is not guaranteed, but sure, now that there is a roundtrip involved, Weston could ask the pixman-renderer if it can handle the tentative new buffer. As you can see, the series is still missing all about the optional mmap path, because we needed the accelerated path working first. > Which GStreamer video sink do you use as client ? > How do you allocate the buffers in this sink ?

https://bugs.freedesktop.org/show_bug.cgi?id=83881 --- Comment #4 from Daniel Stone --- Yeah, the EGL thing is really harsh. One of the main motivations behind wanting a query is to avoid the EGL trap where we literally have no idea, and just have to guess as to which _formats_ are supported. I get that random arbitrary combinations may fail for any reason, but not having a format query is really harsh. -- You are receiving this mail because: You are the assignee for the bug. ___ wayland-bugs mailing list wayland-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/wayland-bugs
