[Bug 2169534] Re: [SRU] Fix NPU errors on Gorgon Halo

This patch is targeting 7.3-oem kernel, but the proper package page hasn't shown up on LP, so file it against the "linux" pcakage for now. Will target to 7.3-oem once it shows up. ** Description changed: - BugLink: https://bugs.launchpad.net/bugs/2169534 + BugLink: [ Impact ] To enable NPU on Gorgon Halo, a new ID needs to be added to the revision list in the driver. Otherwise the amdxdna driver would show the following error message: [ 2.996014] test kernel: amdxdna 0000:c5:00.1: [drm] *ERROR* aie2_get_dev_revision: Unknown device revision: 9 (raw fuse: 0x10170) [ Fix ] - Cherry-pick the following patch to the 7.3-oem kernel: + Cherry-pick the following patch: - [PATCH V2] accel/amdxdna: Add support for AIE2 revision 9[1] - This patch is currently in the drm-misc tree commit - 63e91c1997898f32f68a5dbf68195d68b8e58443. + This patch is currently in the linux-next tree as commit + 63e91c1997898f32f68a5dbf68195d68b8e58443 since next-20260930 [ Test plan ] Boot the kernel.
