topic i.mx8M plus GPU driver in i.MX Graphics https://community.nxp.com/t5/i-MX-Graphics/i-mx8M-plus-GPU-driver/m-p/1663074#M438 <P>Hello,</P><P>I am studying DRM driver for imx8m plus. In the linux kernel source code, I have located the driver source for the CRTC, Encoder and Connector, but where is the GPU driver? I know that the vivante GPU driver is not open source, but I didn't find any .ko files or something. I am posting this question because I want to understand how the GPU works on imx8m plus and how the&nbsp; GPU driver is integrated into DRM driver framework. I know there are core libraries (openGL, vulkan, openCL, .etc) in the user space, but I just want to know how the GPU works in kernel space, i.e., how the GPU handles buffer and command management.</P><P>Thanks!</P> Mon, 05 Jun 2023 02:15:54 GMT chp0423 2023-06-05T02:15:54Z i.mx8M plus GPU driver https://community.nxp.com/t5/i-MX-Graphics/i-mx8M-plus-GPU-driver/m-p/1663074#M438 <P>Hello,</P><P>I am studying DRM driver for imx8m plus.
