Hi Daniel, I've got pretty strange results so I need some time to investigate it and probably retest. I'll send you update in a few days. --- Eugeniy Paltsev From: Daniel Vetter Sent: Friday, June 5, 2020 22:55 To: Eugeniy Paltsev Cc: Intel Graphics D

Hi Daniel, I've already tested it (and found several issues), so please check my reply here: https://www.mail-archive.com/linux-snps-arc@lists.infradead.org/msg07403.html Not sure why you didn't receive my reply (probably the reason is because it was sent to your @ffwll.ch mail instead of @inte
