yes with code from Git, I got "Direct Rendering enabled!" posted on window creation. by changing GL_TRUE to GL_FALSE in gemglxwindow.cpp:303 [1] I don't get this message again but the FPS stay at 60fps (@Cyrille : with pixel_liquide2_57.pd, 1920x1080, framebuffer rendering)
Moreover according to [2], Nvidia's driver are using GLX not DRI but I can't verify this yet. Note that the repo contains an example on how to share texture between 2 process on embedded hardware (EGL) using DRI, maybe this note only apply to embedded Nvidia's driver. + a [1] : https://github.com/avilleret/Gem/blob/master/src/Output/gemglxwindow.cpp#L303 [2] : https://github.com/pcwalton/linux-drm-sharing-test/blob/master/README -- do it yourself http://antoine.villeret.free.fr 2014-10-27 19:17 GMT+01:00 Cyrille Henry <[email protected]>: > how did you get hardware acceleration without DRI? > > cheers > c > > Le 27/10/2014 18:04, Antoine Villeret a écrit : > >> >> why ? how huge ? >> >> I understand that direct rendering could improve performances but >> I can run very GPU expensive patchs you made without direct rendering >> and without noticable difference. >> >> So it may be worth a try... >> >> a >> -- >> do it yourself >> http://antoine.villeret.free.fr >> >> >> 2014-10-27 11:11 GMT+01:00 Cyrille Henry <[email protected]>: >>> >>> >>> >>> Le 27/10/2014 10:41, Antoine Villeret a écrit : >>>> >>>> >>>> hello, >>>> >>>> since texture sharing seems to work between context inside one Gem's >>>> instance, I'm now wondering how we can introduce texture sharing >>>> between process. >>>> According to [1], texture (and more generally display list) can be >>>> shared between process if direct rendering is disabled and process are >>>> using the same X server. >>>> If I understand correctly, the only thing to do is to share the >>>> display list structure over process. >>>> Could we use shared memory to do that ? >>>> >>>> I look into the [gemglxwindow] and [gemglutwindow] code and it looks a >>>> bit obscure to me, it uses advanced C++ idioms (PIMPL for the former >>>> and CALLBACK4WIN for the latter) that I don't understand well yet.
