From 93c2340bdc24b6067a7621e71d4aacac1f85b5f2 Mon Sep 17 00:00:00 2001 From: Martin Leung Date: Tue, 17 Sep 2019 14:50:22 -0400 Subject: drm/amd/display: add more checks to validate seamless boot timing [why] we found using an active DP to HDMI panel that we weren't validating dp_pixel_format and hardware timing v_front_porch, causing screen to blank and/or corrupt while attempting a seamless boot. [how] added checks during dc_validate_seamless_boot_timing for these values Signed-off-by: Martin Leung Reviewed-by: Anthony Koo Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/display/dc/inc/hw/stream_encoder.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'drivers/gpu/drm/amd/display/dc/inc/hw/stream_encoder.h') diff --git a/drivers/gpu/drm/amd/display/dc/inc/hw/stream_encoder.h b/drivers/gpu/drm/amd/display/dc/inc/hw/stream_encoder.h index fe9b7a10a1c3..6305e388612a 100644 --- a/drivers/gpu/drm/amd/display/dc/inc/hw/stream_encoder.h +++ b/drivers/gpu/drm/amd/display/dc/inc/hw/stream_encoder.h @@ -214,6 +214,11 @@ struct stream_encoder_funcs { unsigned int (*dig_source_otg)( struct stream_encoder *enc); + bool (*dp_get_pixel_format)( + struct stream_encoder *enc, + enum dc_pixel_encoding *encoding, + enum dc_color_depth *depth); + #if defined(CONFIG_DRM_AMD_DC_DCN2_0) #ifdef CONFIG_DRM_AMD_DC_DSC_SUPPORT void (*enc_read_state)(struct stream_encoder *enc, struct enc_state *s); -- cgit v1.2.3
