From 3c537889e17232e9073f75ae8710ea0f008c5a29 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 5 Feb 2010 04:21:19 -0500 Subject: drm/radeon/kms: add support for hardcoded edids in rom (v2) Some servers hardcode an edid in rom so that they will work properly with KVMs. This is a port of the relevant code from the ddx. [airlied: reworked to validate edid at boot stage - and remove special quirk, if there is a valid EDID in the BIOS rom we'll just try and use it.] Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie --- drivers/gpu/drm/radeon/radeon_mode.h | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'drivers/gpu/drm/radeon/radeon_mode.h') diff --git a/drivers/gpu/drm/radeon/radeon_mode.h b/drivers/gpu/drm/radeon/radeon_mode.h index b884bacf09f..71439ba2fee 100644 --- a/drivers/gpu/drm/radeon/radeon_mode.h +++ b/drivers/gpu/drm/radeon/radeon_mode.h @@ -207,7 +207,8 @@ struct radeon_mode_info { struct drm_property *tv_std_property; /* legacy TMDS PLL detect */ struct drm_property *tmds_pll_property; - + /* hardcoded DFP edid from BIOS */ + struct edid *bios_hardcoded_edid; }; #define MAX_H_CODE_TIMING_LEN 32 @@ -479,6 +480,9 @@ extern int radeon_crtc_cursor_set(struct drm_crtc *crtc, extern int radeon_crtc_cursor_move(struct drm_crtc *crtc, int x, int y); +extern bool radeon_combios_check_hardcoded_edid(struct radeon_device *rdev); +extern struct edid * +radeon_combios_get_hardcoded_edid(struct radeon_device *rdev); extern bool radeon_atom_get_clock_info(struct drm_device *dev); extern bool radeon_combios_get_clock_info(struct drm_device *dev); extern struct radeon_encoder_atom_dig * -- cgit v1.2.3-70-g09d2
