AMD Ryzen™ 5 3500U如何在20.04下如何安装显卡驱动？

[TOM3550]

AMD Ryzen™ 5 3500U工控小主机，显卡是Radeon™ Vega 8 Graphics，安装的系统是ubuntu server 20.04，安装完成后，sudo radeontop发现显卡占用率一直100%，安装了mesa-opencl-icd以及ocl-icd-libopencl1后，sudo clinfo也能发现设备，但一跑程序就报错，有办法解决吗？

开源驱动是和内核一起的，要用新驱动就安装新内核。
闭源驱动在 https://www.amd.com/en/support/linux-drivers
另外，还是那句话，遇到报错最好把报错信息发上来

版主好，情况是这样，安装了mesa-opencl-icd ocl-icd-libopencl1

看起来，应该正常，但是运行程序后，
terminate called after throwing an instance of 'OpenCLHelpers::CompileError'
what(): CL_INVALID_BUILD_OPTIONS
BUILD LOG FOR conv2dNCHWProgram ON DEVICE 0

不知道发生了什么？

运行5.7版本的sudo apt-get install ./amdgpu_intall_*.deb后，安装amdgpu-install -y --opencl=rocr,legacy，提示找不到文件

这么明晃晃的错误你看不见吗？还“看起来，应该正常”。不知道fatal error的意思就赶紧去查一下字典

fatal error: cannot open file '/usr/local//usr/lib/clc/gfx902-amdgcn-mesa-mesa3d.bc': No such file or directory

从'/usr/local//usr/lib/‘这个路径来看，你肯定有东西安装时搞错路径了。如果你不知道哪一步在指定的路径，也可以在/usr/local下建立一个到/usr的软链接，让这个错误路径变成正确的
gfx902-amdgcn-mesa-mesa3d.bc这个文件是从libclc-13开始有的。ubuntu 20.04上的libclc-12里只有gfx902-amdgcn--.bc。你可以自己建立一个到gfx902-amdgcn--.bc的软链接。

大写的尴尬，好的，版主，我再试试。

升级操作系统不就可以了！
