* [PATCH v3] drm/edid: Complete CEA modedb(VIC 1-107) @ 2017-01-29 5:41 ` Shashank Sharma 2017-01-30 8:00 ` Andrzej Hajda ` (2 more replies) 0 siblings, 3 replies; 11+ messages in thread From: Shashank Sharma @ 2017-01-29 5:41 UTC (permalink / raw) To: dri-devel, gfx-internal-devel Cc: Jose Abreu, =ville.syrjala, Alex Deucher, daniel.vetter CEA-861-F specs defines new 4k video modes to be used with HDMI 2.0 EDIDs. These modes start at VIC=93 and go all the way till VIC=107. Our existing CEA modedb contains only 64 modes (VIC=1 to VIC=64). Now to be able to parse 4k modes using the existing techniques, we have to complete the modedb (VIC=65 onwards). This patch adds: - Timings for existing CEA video modes (from VIC=65 till VIC=92) - Newly added 4k modes (from VIC=93 to VIC=107).

Now, why would a HDMI 1.4 monitor, contain a HDMI 2.0 VIC ?

Let me cite myself: For example 3840x2160@30Hz has no VIC in HDMI 1.4 but it can be present in HDMI vendor specific block with HDMI_VIC 1, on the other side it has VIC 95 in HDMI 2.0. So before your patch AVI infoframe.video_code is set to 0, after your patch is set to 95. And your discussion with Ville: > >/>>> No. The user is free to specify any mode they wish.

I checked the specs again, there are three things here: - The spec has a section on this, and it states that in such cases CEA VIC should be supplied to the AVI IF. - Also, for HDMI infoframe blocks, we dont refer to cea_edid_modes[] rather we go to edid_4k_modes[] - Again, as there is no aspect ratio parsing layer in DRM right now (after the revert), we are doing the right thing to give aspect as per CEA, which is suggested by spec too. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel ^ permalink raw reply [flat|nested] 11+ messages in thread

This phrase is not precise, but if it means that in case of 3840x2160@30Hz source should set VIC to 95 also for HDMI1.4 compliant sinks it is in opposition to statement from HDMI1.4 specification: > When transmitting any extended video format indicated through use of > the HDMI_VIC field > in the HDMI Vendor Specific InfoFrame or any other format which is not > described in the > above cases, an HDMI Source shall set the AVI InfoFrame VIC field to zero.

As edid_cea_modes is being used in drm_hdmi_avi_if_from_display_mode, only place where its being used to load AVI IF (with aspect ratio information), I was talking about both. But lets talk about VIC only from here.

Looks like CEA-861-F also defines news VICs in the range 193-253 as well. The way we're parsing things at the moment would actually confuse those with the ones we already have. So it looks to me like more work is needed to parse all the new stuff correctly. And the way the spec lays stuff out makes me think that we might not necessarily want to stuff anything with VIC 65 or higher into the existing table. > > Cc: Jose Abreu <Jose.Abreu@synopsys.com> > Cc: Alex Deucher <alexander.deucher@amd.com> > Cc: Andrzej Hajda <a.hajda@samsung.com> > > V2: Addressed review comments from Jose: > -
