From 49e02b7306cb7e01965fe5f41ba0f80085142f6e Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 23 Apr 2010 17:57:27 -0400 Subject: drm/radeon/kms/pm: add additional asic callbacks - pm_misc() - handles voltage, pcie lanes, and other non clock related power mode settings. Currently disabled. Needs further debugging - pm_prepare() - disables crtc mem requests right now. All memory clients need to be disabled when changing memory clocks. This function can be expanded to include disabling fb access as well. - pm_finish() - enable active memory clients.
