From 7db61d72405847d0e2d5ba0e5fa1d43c8b81e68f Mon Sep 17 00:00:00 2001 From: David Francis Date: Thu, 28 Mar 2019 13:52:00 -0400 Subject: [PATCH 3497/4256] Revert "drm/amd/display: skip dsc config for navi10 bring up" This reverts commit 55ad81f3510ec1a1c19e6a4d8a6319812d07d256. optc dsc config was causing warnings due to missing register definitions. With the registers restored, the function can be re-enabled The reverted commit also disabled sanity checks and dsc power gating. The sanity check warnings are not associated with dsc, and power gating on dsc still has an issue on non-dsc monitors where the dsc hardware block is never init and so cannot respond to power gating requests. Therefore, those are left as is Signed-off-by: David Francis Reviewed-by: Roman Li Reviewed-by: Harry Wentland Reviewed-by: Nicholas Kazlauskas --- drivers/gpu/drm/amd/display/dc/dcn20/dcn20_optc.c | 9 --------- 1 file changed, 9 deletions(-) diff --git a/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_optc.c b/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_optc.c index aedf9de1c947..99070e93020b 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_optc.c +++ b/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_optc.c @@ -191,15 +191,6 @@ void optc2_set_dsc_config(struct timing_generator *optc, uint32_t dsc_slice_width) { struct optc *optc1 = DCN10TG_FROM_TG(optc); - uint32_t data_format = 0; - /* skip if dsc mode is not changed */ - data_format = dm_read_reg(CTX, REG(OPTC_DATA_FORMAT_CONTROL)); - - data_format = data_format & 0x30; /* bit5:4 */ - data_format = data_format >> 4; - - if (data_format == dsc_mode) - return; REG_UPDATE(OPTC_DATA_FORMAT_CONTROL, OPTC_DSC_MODE, dsc_mode); -- 2.17.1
