* patches: Identify APUs from hardware (LP: #2127944) -- Timo Aaltonen <[email protected]> Thu, 23 Oct 2025 17:33:16 +0300 ** Changed in: libdrm (Ubuntu Resolute) Status: New => Fix Released -- You received this bug notification because you are a member of Debcrafters packages, which is subscribed to libdrm in Ubuntu. https://bugs.launchpad.net/bugs/2127944 Title: Identify APUs from hardware Status in libdrm package in Ubuntu: Fix Released Status in libdrm source package in Noble: New Status in libdrm source package in Questing: New Status in libdrm source package in Resolute: Fix Released Bug description: [Impact] libdrm has an interface that is used by a variety of software (such as GNOME about dialog, nvtop, rocminfo etc) to describe the GPU connected to the system. libdrm by default will try to match an AMD GPU to lines in amdgpu.ids. If there is no match it will fall back to "Radeon Graphics". This is a constant game of cat and mouse because every single SKU of a new product needs a line added. On APUs this is unnecessary though. The string that comes from /proc/cpuinfo describing the model comes from the hardware itself. A change has been made in upstream libdrm that will fall back to this string when working on an APU and nothing is found in amdgpu.ids file. [Where problems could occur] Problems would be localized to exposing the strings that came from /proc/cpuinfo. [Test Plan] * Verify dGPU string in amdgpu.ids shows up properly in GNOME / Settings / About * Verify on an unknown APU string matches substring from /proc/cpuinfo in GNOME / Settings / About (or modify amdgpu.ids locally to prove this out).
