2021-12-22 11:54:53 jeremyszu description [Impact] * iris driver doesn't load with pci_id 4688. Instead, it uses llvm. we expect the Intel GPU uses iris driver. [Test Plan] * $ DISPLAY=:0 glxinfo | grep -i opengl OpenGL vendor string: Mesa/X.org OpenGL renderer string: llvmpipe (LLVM 12.0.0, 256 bits) ... OpenGL version string: 3.1 Mesa 21.0.3 * After applying the fix, it shows: * $ DISPLAY=:0 glxinfo | grep -i opengl OpenGL vendor string: Intel OpenGL renderer string: Mesa Intel(R) Graphics (ADL-S GT1) ... OpenGL version string: 4.6 (Compatibility Profile) Mesa 21.0.3 (git-d4975a0dbc) [Where problems could occur] * This patch is backport the PCI ID mapping for enabling iris driver which is expected when users have a GPU. * If there is any issue occur then we need to fix it with iris driver. [Other Info] * It already in upstream and we have a platform which using ADL-HX in OEM project. Thus, we need to enable iris on it at least on focal. * The patch is simple as to add "CHIPSET(0x4688, adl_gt1, "ADL-S GT1", "Intel(R) Graphics")" in "include/pci_ids/iris_pci_ids.h".
