Hi,

Please cherry-pick following 9 patches to 6.12: 525a3858aad73 accel/ivpu: Set 500 ns delay between power island TRICKLE and ENABLE 08eb99ce911d3 accel/ivpu: Do not fail on cmdq if failed to allocate preemption buffers 755fb86789165 accel/ivpu: Use whole user and shave ranges for preemption buffers 98110eb5924bd accel/ivpu: Increase MS info buffer size c140244f0cfb9 accel/ivpu: Add initial Panther Lake support 88bdd1644ca28 accel/ivpu: Update power island delays ce68f86c44513 accel/ivpu: Do not fail when more than 1 tile is fused 83b6fa5844b53 accel/ivpu: Increase DMA address range e91191efe75a9 accel/ivpu: Move secondary preemption buffer allocation to DMA range

These add support for new Panther Lake HW. They should apply without conflicts.

That's way larger than the normal "add a new quirk or device id" patch for new device support, right? Why do you feel this is needed and relevant for 6.12.y and meets the requirements that we have for stable kernel patches?

thanks,
