Hi Helmut,
Thanks for reporting this. Does your linux-firmware have this change?
https://gitlab.com/kernel-firmware/linux-firmware/-/commit/58cf579b98c0c4878deeda1acb5db70e699875b5
Under the same firmware directory, there should be npu_7.sbin which
links to npu.sbin.1.1.2.64. This is for the latest driver.
And npu.sbin still links to npu.sbin.1.0.0.63 which is for previous drivers.
Could you check if the symbol links are created as expected under
amdnpu/17f0_10/?
Thanks,
Lizhi

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)

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.
