Hi, while investigating a problem with a radeon 550 based graphics card (using amdgpu it works with Linux in two amd64 boxes, but only in one of them with NetBSD) I found that one of the differences between Linux between Linux and NetBSD is that Linux maps the graphics memory somewhere else from what the BIOS/UEFI had mapped it. That is because it wants to be able to access all of the card's memory (2 GB on my card) directly from the cpu, while the BIOS/UEFI likes to support 32 bit OSs and therefor has to map part of that memory below the 4GB limit.
Are there any plans and/or work going on to support something like this in NetBSD? Ciao, Wolfgang -- wolfg...@solfrank.net Wolfgang Solfrank
