Hi Daksh,

Thanks a lot for testing!

Just a heads-up: I already sent v3 a few days ago:
https://lore.kernel.org/all/20261110121534.3566028-1-karol.wachowski@linux.intel.com/

which includes a small adjustment in ivpu_pm_reset_complete() so 
autosuspend isn't lost after a reset (reported by Sashiko).

Because of this change, I haven't carried over your Tested-by tag 
automatically. If you happen to have a spare moment to give v3 a quick 
spin, that would be great, otherwise no worries I've already have your 
Reported-by tag.

Thanks,
Karol
