Subject: [PATCH 0/2] Enable_psr kernel parameter changes
Date: Mon, 7 Jul 2025 13:47:31 +0300 [thread overview]
Message-ID: <20250707104733.1874797-1-jouni.hogander@intel.com> (raw)
Currently setting enable_psr kernel parameter to != -1 is disabling
Panel Replay and Early Transport. This patch set is changing
enable_psr meaning as follows:
-1 = PSR1 : yes, PSR2 = yes, Panel Replay : yes
0 = PSR1 : no, PSR2 = no, Panel Replay : no
1 = PSR1 : yes, PSR2 = no, Panel Replay : yes
2 = PSR1 : yes, PSR2 = yes, Panel Replay : no
I.e. 1 disables PSR2 and 2 disables Panel replay. 0 disables PSR/Panel
Replay completely. Enable_psr parameter doesn't impact Early Transport
anymore.
Jouni Högander (2):
drm/i915/psr: Do not disable Early Transport when enable_psr is set
drm/i915/psr: Do not disable Panel Replay if PSR2 is disabled
