From: Vincente Tsou <[email protected]> The upper bits of the vsync width, vsync offset and hsync width were not parsed from the VBT. Parse these fields in this patch.
V2: Renamed lvds dvo timing structure members and code identation fix (Jani's review comments) V3: Corrected commit message, used "from the VBT" Signed-off-by: Vincente Tsou <[email protected]> Signed-off-by: Madhav Chauhan <[email protected]> --- drivers/gpu/drm/i915/intel_bios.c | 8 +++++--- drivers/gpu/drm/i915/intel_vbt_defs.h | 12 +++++++----- 2 files changed, 12 insertions(+), 8 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_bios.c b/drivers/gpu/drm/i915/intel_bios.c index a359def..f6d3755 100644 --- a/drivers/gpu/drm/i915/intel_bios.c +++ b/drivers/gpu/drm/i915/intel_bios.c @@ -114,16 +114,18 @@ static u32 get_blocksize(const void *block_data) panel_fixed_mode->hsync_start = panel_fixed_mode->hdisplay + ((dvo_timing->hsync_off_hi << 8) | dvo_timing->hsync_off_lo); panel_fixed_mode->hsync_end = panel_fixed_mode->hsync_start + - dvo_timing->hsync_pulse_width; + ((dvo_timing->hsync_pulse_width_hi << 8) | + dvo_timing->hsync_pulse_width_lo); panel_fixed_mode->htotal = panel_fixed_mode->hdisplay + ((dvo_timing->hblank_hi << 8) | dvo_timing->hblank_lo); panel_fixed_mode->vdisplay = (dvo_timing->vactive_hi << 8) | dvo_timing->vactive_lo; panel_fixed_mode->vsync_start = panel_fixed_mode->vdisplay + - dvo_timing->vsync_off; + ((dvo_timing->vsync_off_hi << 4) | dvo_timing->vsync_off_lo); panel_fixed_mode->vsync_end = panel_fixed_mode->vsync_start + - dvo_timing->vsync_pulse_width; + ((dvo_timing->vsync_pulse_width_hi << 4) | + dvo_timing->vsync_pulse_width_lo); panel_fixed_mode->vtotal = panel_fixed_mode->vdisplay + ((dvo_timing->vblank_hi << 8) | dvo_timing->vblank_lo); panel_fixed_mode->clock = dvo_timing->clock * 10; diff --git a/drivers/gpu/drm/i915/intel_vbt_defs.h b/drivers/gpu/drm/i915/intel_vbt_defs.h index 8886cab1..a92e776 100644 --- a/drivers/gpu/drm/i915/intel_vbt_defs.h +++ b/drivers/gpu/drm/i915/intel_vbt_defs.h @@ -399,10 +399,12 @@ struct lvds_dvo_timing { u8 vblank_hi:4; u8 vactive_hi:4; u8 hsync_off_lo; - u8 hsync_pulse_width; - u8 vsync_pulse_width:4; - u8 vsync_off:4; - u8 rsvd0:6; + u8 hsync_pulse_width_lo; + u8 vsync_pulse_width_lo:4; + u8 vsync_off_lo:4; + u8 vsync_pulse_width_hi:2; + u8 vsync_off_hi:2; + u8 hsync_pulse_width_hi:2; u8 hsync_off_hi:2; u8 himage_lo; u8 vimage_lo; @@ -414,7 +416,7 @@ struct lvds_dvo_timing { u8 digital:2; u8 vsync_positive:1; u8 hsync_positive:1; - u8 rsvd2:1; + u8 non_interlaced:1; } __packed; struct lvds_pnp_id { -- 1.9.1 _______________________________________________ Intel-gfx mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/intel-gfx
