...s/DRI/nouveau Assignee: nouveau at lists.freedesktop.org Reporter: contact at emersion.fr QA Contact: nouveau at lists.freedesktop.org When creating an EGL context with EGL_PLATFORM_GBM_MESA and EGL_ALPHA_SIZE=1, Nouveau produces completely transparent images when using glReadPixels. Note that my code works with other drivers (i915, amdgpu), only Nouveau is affected. How to reproduce: 1. Create an EGL context with these attribs: static const EGLint config_attribs[] = { EGL_RED_SIZE, 1, EGL_GREEN_SIZE, 1, EGL_BLUE_SIZE, 1, EGL_ALPHA_SIZE, 1,...

Hello, I am testing some OpenGL software that uses a DIB backed device context followed by a BitBlt operation to draw graphics on to an on-screen canvas. Unfortunately this does not seem to work.? I have tried to patch the latest wine with DIB engine patches (bug 421), but, was unable to get it working still. My question(s) are: 1) Is this a known issue? 2) Is it in the scope of the DIB engine

Hi total wine noob here - please spell things out a bit... the error i get that stops me from from loading medieval II is > fixme:d3d:IWineD3DDeviceImpl_CreateAdditionalSwapChain The app requests more than one back buffer, this can't be supported properly. Please configure the application to use double buffering(=1 back buffer) if possible and the how-to for this game says to go to

...de has not changed in a long time, so it's likely, although not certain, that the problem lies with CentOS 7. I know very little about graphics, but it seems to me from looking at the rgl source code that the fundamental work of rgl.snapshot is done by calls to glReadBuffer, glPixelStorei, and glReadPixels, which seem to be functions in the OpenGL library. Can anyone take a look at this or advise me on how to proceed?

...using ttm_bo_ioremap(), so it really seems to be unhappy with the WC mapping itself. Note that if I go ahead and force the use of pgprot_writecombine() in ttm_io_prot() to get writecombined user-space mappings, pure DRM programs that map a buffer and try to read it fail similarly, while Mesa's glReadPixels() seems to be happy. I'm not sure what it does differently here. Cheers, Alex.

Are you using the EPEL R 3.2.3 builds? What version of Centos 7? 7.2? Is the NVIDIA driver in play? What version of the NVIDIA driver are you using? ~tom == Red Hat

Hi everyone, Here is the second batch of patches to add GK20A support to Nouveau. This time we are adding the actual chip support, and this series brings the driver to a point where a slightly-tweaked Mesa successfully runs shaders and renders triangles on GBM! Many thanks to Thierry Reding and the people on the #nouveau IRC channel for their help without which we would not have reached this
