From: Vandana Kannan <[email protected]> The port detection register flags in SFUSE_STRAP and DDI_BUF_CTL_A are not defined for BXT, so don't use them.
Suggested by Satheesh. v2: - DDI_BUF_CTL_A bit 0 is not useful on BXT. Making changes to use this bit when simulator or BXT is not applicable. Code re-arranged as per Damien's suggestion. v3: - clarify commit message, add code comment (imre) Signed-off-by: Vandana Kannan <[email protected]> (v2) Cc: M, Satheeshakrishna <[email protected]> Cc: Lespiau, Damien <[email protected]> Cc: Shankar, Uma <[email protected]> Signed-off-by: Imre Deak <[email protected]> --- drivers/gpu/drm/i915/intel_display.c | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 90b460c..e54e948 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -12615,7 +12615,16 @@ static void intel_setup_outputs(struct drm_device *dev) if (intel_crt_present(dev)) intel_crt_init(dev); - if (HAS_DDI(dev)) { + if (IS_BROXTON(dev)) { + /* + * FIXME: Broxton doesn't support port detection via the + * DDI_BUF_CTL_A or SFUSE_STRAP registers, find another way to + * detect the ports. + */ + intel_ddi_init(dev, PORT_A); + intel_ddi_init(dev, PORT_B); + intel_ddi_init(dev, PORT_C); + } else if (HAS_DDI(dev)) { int found; /* -- 2.1.0 _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
