Reboot. + + 2. Wither kernel lower than , it gives no much information on a successful fw load: + ``` + intel_vpu 0000:00:0b.0: enabling device (0000 -> 0002) + [drm] Initialized intel_vpu 1.0.0 20230117 for 0000:00:0b.0 on minor 0 + ``` + With kernels >= v6.6, it prints also firmware version info by default: + ``` + intel_vpu 0000:00:0b.0: enabling device (0000 -> 0002) + intel_vpu 0000:00:0b.0: [drm] Firmware: intel/vpu/vpu_37xx_v0.0.bin, version: 20251016*MTL_CLIENT_SILICON-release*1600*ci_tag_ud202544_vpu_rc_20251016_1600*74b0ef77ba8 + [drm] Initialized intel_vpu 1.0.0 20230117 for 0000:00:0b.0 on minor 0 + ``` + + [ Where problems could occur ] + + Opaque firmware. The previous SAUCE firmware blob was retrieved from + Intel's NPU driver github, which is also the source of those been + upstreamed to kernel org linux-firmware repo. + + [ Other Info ] + + The firmware paths changed a few times: + + 1. kernels < v6.6: + - mtl_vpu.bin + - intel/vpu/mtl_vpu_v0.0.bin + + 2. kernels < v6.9: + - vpu_37xx.bin + - mtl_vpu.bin + - intel/vpu/vpu_37xx_v0.0.bin + + 3. otherwise: + - vpu_37xx.bin + - intel/vpu/vpu_37xx_v0.0.bin + - intel/vpu/vpu_37xx_v1.bin + + In order to keep all Jammy kernels (ivpu supported since kernel v6.3) + working, an additional symlink "intel/vpu/mtl_vpu_v0.0.bin" was added to + Jammy backport. + + Nominate for J, N, Q, R as Intel MTL platforms (which has vpu 37xx) was + supported in these series. + + ========== original bug report ========== + Intel VPU support starts with Jammy, and its last update is https://github.com/intel/linux-npu-driver/releases/tag/v1.26.0 as upstream commit 214b4374c0e9 ("intel_vpu: Update NPU firmware").
