            Bug ID: 105880
           Summary: [dc][kabini] Cannot find any crtc or sizes
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: chithanh@gentoo.org

Created attachment 138570
  --> https://bugs.freedesktop.org/attachment.cgi?id=138570&action=edit
dmesg with cik_support=1 dc=1

When using kernel 4.16.0 and amdgpu with cik_support=1 dc=1 on Kabini (A4-1200)
the screen will become blank once the module is loaded.

dmesg has the following error:
[drm] Cannot find any crtc or sizes

With radeon or amdgpu.dc=0 the screen lights up, but I cannot use amdgpu for
daily work due to bug 101926.

Looks like we don't detect a display. Can you capture dmesg with cik_support=1
dc=1 dc_log=1 to get more log info?

Hi,

I'm getting the same or similar error:
 * Black screen, no plymouth
 * "Cannot find any crtc or sizes" error in dmesg
 * amdgpu.dc=0 works around the issue

...and I might have a lead on it. The regression is between 4.15rc2 and 4.15rc3
(found by downloading kernels from
http://kernel.ubuntu.com/~kernel-ppa/mainline/). 

The only one commit I could see being relevant between 4.15rc2 and 4.15rc3 is
this one:

commit a703c55004e1c5076d57e43771b3e11117796ea0
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date: Mon Dec 4 21:48:18 2017 +0100

    drm: safely free connectors from connector_iter

...it seems relevant because the error I get is "Cannot find any crtc or
sizes", and the code emitting this error message (in
drivers/gpu/drm/drm_fb_helper.c) deals with connectors.

So could this commit cause connectors to be freed where the previous code did
not? It seems like this could be the case, but only if (obj->free_cb == NULL) -
drm_connector_put checks for a obj->free_cb being null whereas
drm_connector_put_safe decrements a refcount regardless of whether a free_cb is
present or not.

Does all this make sense, or am I out on deep water here?

dmesg from kernel 4.15 with cik_support=1 dc=1 dc_log=1

Going back to kernel 4.15 makes no difference for me. I think that the issue
reported in comment 8 is different and should be reported in a separate bug.

Though I noticed that in 4.15, dc_log=1 gives more output than in 4.16 where it
doesn't make any difference.

--- Comment #12 from Chí-Thanh Christopher Nguyễn <chithanh@gentoo.org> ---
So, with the additional dmesg output from kernel 4.15, the following appeared
interesting:

[   43.356569] [drm] DC: create_links: connectors_num: physical:3, virtual:0
[   43.356583] [drm] Unsupported Connector type:14!
[   43.356588] [drm] Connector[1] description:signal 4
[   43.356617] [drm] Unsupported Connector type:5!

If I understand drivers/gpu/drm/amd/dal/dc/core/dc_link.c correctly, the
following connector types are supported in construct()

CONNECTOR_ID_HDMI_TYPE_A
CONNECTOR_ID_SINGLE_LINK_DVID
CONNECTOR_ID_SINGLE_LINK_DVII
CONNECTOR_ID_DUAL_LINK_DVID
CONNECTOR_ID_DUAL_LINK_DVII
CONNECTOR_ID_DISPLAY_PORT
CONNECTOR_ID_EDP

else the following code will print the above error message

                dal_logger_write(dc_ctx->logger,
                        LOG_MAJOR_WARNING, LOG_MINOR_TM_LINK_SRV,
                        "Unsupported Connector type:%d!\n", link->link_id.id);

According to display/include/grph_object_id.h

CONNECTOR_ID_VGA = 5
CONNECTOR_ID_LVDS = 14

which would explain why no working connectors are found. I will try to find an
HDMI monitor to see if it lights up with amdgpu DC.

Ok, so display connected via HDMI will light up with kernel 4.16. The issue is
therefore that DC lacks LVDS and VGA support.

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.

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).

dmesg from kernel 4.15 with attachment 138831 applied

So I applied this patch from bug 105596

The "Unsupported Connector type:14" message is gone, the "Unsupported Connector
type:5" is still there (as expected).

However the screen stays blank and the "[drm] Cannot find any crtc or sizes"
message sill comes.

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.

[Bug 105880] [dc] No support for LVDS or VGA connectors (Cannot find any crtc or sizes)

--- Comment #19 from Chí-Thanh Christopher Nguyễn <chithanh@gentoo.org> ---
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.

I got to here from the bug detailed in Ubuntu Launchpad -
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1761751

It looks like amdgpu code does not support VGA on Kaveri, either.

I have a Lenovo Z50-75 laptop with AMD A10-7300, (Kaveri gpu)

information extracted from #lshw when booted with amdgpu.dc=0 [some information

Just to supplement the list above.

Netbook Lenovo g50-45, a6-6310 R4 Beema/Mullins.

Has HDMI and VGA output.

HDMI is working without a hitch, while VGA output is dead.(eDP plus only one
extra monitor connected at a time)

Thanks,
Przemek.

Harry, in accordance to this:
https://cgit.freedesktop.org/~agd5f/linux/commit/?h=drm-next-4.19-wip&id=1664ee4f0ae984e28409ad1ac83641539781840c
if you need a 'guinea pig' on that case please let me know. I have "0" (ZERO)
knowledge messing with kernel drivers but with gentoo it is not a big deal for
me to play with two kernels and test some (even a bad) code on that machine
(mullins/VGA connector). IMHO it could help with other ASICSs also.
Thanks,
Przemek.

Given the commit to the kernel

https://lkml.org/lkml/2018/7/6/30

and the same commit going into the 4.18 tree

https://patchwork.freedesktop.org/patch/230643/

can Harry Wentland or Alex Deucher clarify if DC code is planned at some later
stage to support Bonaire, Kabini, Kaveri, and Mullins rather than falling back
to the non-DC driver?

Is there anything owners of such hardware can do to assist?

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.  Old DAL2
code for reference:

Thank-you for the swift response, Alex.

Coding this is certainly beyond my current capabilities - I would have a rather
steep learning curve. I hope this is an itch somebody with the right experience
suffers with and wishes to scratch. ;-)

Nonetheless, thank-you for making such great strides with open drivers. It is
much appreciated.

Pontus.

With latest patch against amd-staging-drm-next the LVDS display panel lights up
only (as this did also before).

Doesn't work yet :/

patch against 4.18.1

I tried the latest patch too, and LVDS is now working (as expected, VGA does
not work).

I slightly adapted the patch so that it applies against linux 4.18.1, in case
anyone is interested.

Good news,
on amd-staging-drm-next (5.0.0-rc1+) vga connector works without a hitch. I
don't have dvi connector on my netbook so I am unable to test this one.

Thanks,

I *think* that is because it defaults to Radeon code on Kaveri.

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.

Apologies, you are right, I was messing with efibootmgr and lost amdgpu.dc=1
somewhere.

Once again sorry for misleading.
