From: Paulo Zanoni <paulo.r.zanoni at intel.com> This function returns the VIC of the mode. This value can be used when creating AVI InfoFrames. Cc: Thierry Reding <thierry.reding at avionic-design.de> Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=50371 Signed-off-by: Paulo Zanoni <paulo.r.zanoni at intel.com> --- drivers/gpu/drm/drm_edid.c | 19 +++++++++++++++++++ include/drm/drm_crtc.h | 1 + 2 files changed, 20 insertions(+) Since drm-intel-next-queued is too old for this patch, I am rebasing it against drm-next and splitting into 2 patches: one drm-only and the other i915-only, so I imagine the first will be merged by Dave and the second by Daniel. New version: - Based on Dave's drm-next - Fix function name inside the comments - Remove the i915 chunk - Constification of other functions is no more required as they are already const here. diff --git a/drivers/gpu/drm/drm_edid.c b/drivers/gpu/drm/drm_edid.c index 1648200..011bd4f 100644 --- a/drivers/gpu/drm/drm_edid.c +++ b/drivers/gpu/drm/drm_edid.c @@ -2079,3 +2079,22 @@ int drm_add_modes_noedid(struct drm_connector *connector, return num_modes; } EXPORT_SYMBOL(drm_add_modes_noedid); + +/** + * drm_mode_cea_vic - return the CEA-861 VIC of a given mode + * @mode: mode + * + * RETURNS: + * The VIC number, 0 in case it's not a CEA-861 mode. + */ +uint8_t drm_mode_cea_vic(const struct drm_display_mode *mode) +{ + uint8_t i; + + for (i = 0; i < drm_num_cea_modes; i++) + if (drm_mode_equal(mode, &edid_cea_modes[i])) + return i + 1; + + return 0; +} +EXPORT_SYMBOL(drm_mode_cea_vic); diff --git a/include/drm/drm_crtc.h b/include/drm/drm_crtc.h index c0635b7..3538eda 100644 --- a/include/drm/drm_crtc.h +++ b/include/drm/drm_crtc.h @@ -1055,6 +1055,7 @@ extern struct drm_display_mode *drm_gtf_mode_complex(struct drm_device *dev, int GTF_2C, int GTF_K, int GTF_2J); extern int drm_add_modes_noedid(struct drm_connector *connector, int hdisplay, int vdisplay); +extern uint8_t drm_mode_cea_vic(const struct drm_display_mode *mode); extern int drm_edid_header_is_valid(const u8 *raw_edid); extern bool drm_edid_block_valid(u8 *raw_edid, int block, bool print_bad_edid); -- 1.7.10.4
