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

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: 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.
