From 77ab79b9e4f351b182dbd4670bee7a28a1140a08 Mon Sep 17 00:00:00 2001 From: Zack Rusin Date: Mon, 9 Dec 2024 09:49:04 +0000 Subject: [PATCH] drm/ttm: Print the memory decryption status just once MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit 27906e5d78248b19bcdfdae72049338c828897bb upstream. Stop printing the TT memory decryption status info each time tt is created and instead print it just once. Reduces the spam in the system logs when running guests with SEV enabled.
