https://bugs.freedesktop.org/show_bug.cgi?id=105880 --- Comment #43 from Pontus Gråskæg --- (In reply to Przemek from comment #42) > Good news, > on amd-staging-drm-next (5.0.0-rc1+) vga connector works without a hitch.

On my Lenovo Z50-75 laptop with kernel 5.0.0-rc4 I get the following behaviour - with kernel parameter amdgpu.dc=0 the VGA connector works (case (a) below) and with amdgpu.dc=1 it does not, although the built in LCD display on the laptop does (case (b) below). I believe this is known to AMD, but resource prioritisation means that it is unlikely to be changed in the near future if at all. graaskaeg a) with kernel boot parameters "amdgpu.cik_support=1 radeon.cik_support=0 amdgpu.dc=0 amdgpu.dc_log=0 drm.debug=0x00 vt.handoff=1" - note the amdgpu.dc=0 My ***Highlight*** added below [2.200714] [drm] amdgpu kernel modesetting enabled.

Someone needs to implement support for LVDS and DACs. It's not a high priority for us at the moment. If someone wants to take a stab at it, we'd be happy to review the patches. I think some of the older DAL2 code had some support for these encoders. You could use that or the non-DC code as reference.

[Bug 105880] [dc] No support for LVDS or VGA connectors (Cannot find any crtc or sizes)
https://bugs.freedesktop.org/show_bug.cgi?id=105880 --- Comment #19 from Chí-Thanh Christopher Nguyễn --- Per https://lists.freedesktop.org/archives/amd-gfx/2018-May/022021.html it seems that AMD developers lack hardware to implement LVDS/VGA support at this time. KABINI devices with VGA, DVI-I and/or LVDS connectors are still possible to buy in the market. Supermicro H9SKV-420 Fujitsu D3313 both available via ebay. In Europe one can find pre-owned Medion E1317T and E1318T too. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

So I did the bisection (which took some time) and it turned out empty. What tricked me was the fact that Ubuntu changed their kernel configs between 4.15rc2 and 4.15rc3, mainly by enabling CONFIG_DRM_AMD_DC_PRE_VEGA and CONFIG_DRM_AMD_DC_DCN1_0. This was the cause of regression for me rather than patches between rc2 and rc3. Anyhow, it's probably a separate bug from this one, so sorry for the confusion. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

However the screen stays blank and the "[drm] Cannot find any crtc or sizes" message sill comes. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugs.freedesktop.org/show_bug.cgi?id=105880 --- Comment #16 from Chí-Thanh Christopher Nguyễn --- I tried with 4.16, made no difference. But as dc_log=1 on 4.16 gives no helpful additional output, I will try on Monday with 4.15 again. It may also be possible that I am affected both by the issue in this bug and what was reported in comment 8 (but discussion about which should be continued in a separate bug report). -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

I can, but it'll take a week or two at current speed... Also because the original reporter now seem to refer to something specific to LVDS we probably have different bugs, unfortunately. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
