Re: [Nouveau] Is binary firmware still necessary for GTX660 card (NVE0 family) in order to use DRM and/or VDPAU video acceleration?
Hi, just a note for everybody who stumble across this thread in the future in order to bring this thread to a proper end. If I run the kernel with nouveau.debug=PVP=debug,PBSP=debug,=debug I see messages about the firmware files gettings loaded. If the firmware files are missing, I get some warnings/errors. So far everything works as expected. But if I invoke mplayer with the -vo vdpau -vc ... option either way mplayer claims to use vdpau and starts playing the video, even if the firmware files are not there. Hence, either mplayer or the nouveau driver can do vdpau without the firmware files, but then I wonder how, or mplayer silently falls back to another output driver. Anyway, as far as I am concerned, the issue is closed. I use vdpau with the firmware files and I am happy. Matthias Am Donnerstag, 12.

It should all be detailed in mplayer's output as to what precisely is going on. VDPAU stands for Video Decoding *and* Presentation. You can use it for presentation even if you don't use it for decoding (and vice versa). You only need the firmware for decoding, presentation is just displaying textures on the screen.

Le 12/12/2013 08:58, Matthias Nagel a écrit : Hi Martin, if you refer to my kernel version. 3.10.17 is the latest, stable version in the official gentoo repository for the amd64 architeture. See here ... [4] https://packages.gentoo.org/package/sys-kernel/gentoo-sources?full_cat As long as I do not miss any features, I stay with the stable version. Indeed, you are doing the right thing, I guess. But if you encounter any sort of crash, I really advise you to go against gentoo on this and update your kernel to the latest official release (3.12.x at the moment). FYI, the 3.12 brings performance improvements to Nouveau too. Hence, if I understand you correctly, there are kernel version (newer than some unknown point in time) that already include the firmware? If this is the case, someone who knows the exact kernel version should mention that point on [1] http://nouveau.freedesktop.org/wiki/InstallDRM/ [2] http://nouveau.freedesktop.org/wiki/VideoAcceleration/ [3] https://bugs.gentoo.org/show_bug.cgi?id=480832 and update the information. What I wanted to say is that adding good fw support usually spans across multiple kernels. Even 3.13 has kepler fw fixes IIRC and 3.14 will receive some more updates to support new chipsets. It isn't a binary thing so this is hard to tell we support a feature... I guess we could tell when is the first free implementation (with the possible fallback of using the blob's firmware[1]) and then when we added support for all chipsets of the family and it has been fairly-extensively tested and bug-free. Some cards would never pass the test though :s [1] NvGrUseFw, http://nouveau.freedesktop.org/wiki/KernelModuleParameters/ Cheers, Martin http://nouveau.freedesktop.org/wiki/KernelModuleParameters/ ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau
