Hello, I recently attempted updating my linux-firmware. This included updating amdnpu/17f0_10/npu.sbin.1.0.0.63 to amdnpu/17f0_10/npu.sbin.1.1.2.64. Once loading the new firmware, I see the following messages on a Debian 6.19.6+deb14+1-amd64 kernel:
amdxdna 0000:66:00.1: enabling device (0000 -> 0002) amdxdna 0000:66:00.1: [drm] *ERROR* aie2_check_protocol: Incompatible firmware protocol major 7 minor 2 amdxdna 0000:66:00.1: [drm] *ERROR* aie2_hw_start: firmware is not alive amdxdna 0000:66:00.1: [drm] *ERROR* aie2_smu_exec: smu cmd 4 failed, 0xff amdxdna 0000:66:00.1: [drm] *ERROR* aie2_smu_fini: Power off failed, ret -22 amdxdna 0000:66:00.1: [drm] *ERROR* aie2_init: start npu failed, ret -22 amdxdna 0000:66:00.1: [drm] *ERROR* amdxdna_probe: Hardware init failed, ret -22 amdxdna 0000:66:00.1: probe with driver amdxdna failed with error -22 This indicates that the updated firmware is incompatible with a 6.19 series kernel. A web search suggests that a 7.0+ kernel requires a npu firmware >= 1.1. This is an ABI break. When the interface changes in incompatible ways, the firmware filename should change to avoid such confusion. The firmware upgrade should be supplying both firmware versions as long as 6.19 remains supported. Helmut
