BPI-R2: HDMI 4k-TV fail

Hi,

Recently I’ve tried connecting my R2 to 4k TV, using HDMI and got failed with the next dmesg trace:

hdmi_4k_trace.txt (14.6 КБ)

5.10.38-bpi-r2-hnat+gmac2

No HDMI signal on TV, but works w/o any problems with resolution 1080 or less.

The same behaviour on kernel 5.9.

P.S. I didn’t yet tried to force 1080 in kernel bootargs.

P.P.S. The same TV and the same cable works with other SoCs and laptop.

As far as i see it is a warn_on()

WARNING: CPU: 0 PID: 83 at drivers/gpu/drm/drm_atomic_helper.c:1512 drm_atomic_helper_wait_for_vblanks

I guess this is because no usable resolution is found…can you try setting 1080p via cmdline?

tried on my 4k monitor with forced resolution to 1920x1080

fbcon seems good…see message running through, but at time x-server starts i get this:

mhm, lower resolutions are broken too…afair at least on 5.10 hdmi was working…so any commit breaks it

  • 5.10.11-bpi-r2-main is good on my normal monitor (1280x1024)
  • 5.10.32-bpi-r2-hnat is still good on normal monitor
  • 5.10.38-hnat+gmac2 is still good on this monitor

so 5.10 seems to have only troubles with 4k Monitor

5.13 is broken on my monitor

hangs at

so at least something between 5.11 and 5.12 breaks current supported hdmi resolutions…and a generic 4k-problem (with forced 1080p)

there is a bunch of commits which may break between 5.11 and 5.12

    drm/mediatek: mtk_dpi: Create connector for bridges
    
    Similar to commit a9d9fea74be2
    ("drm/mediatek: mtk_dsi: Create connector for bridges"):
    
    Use the drm_bridge_connector helper to create a connector for pipelines
    that use drm_bridge. This allows splitting connector operations across
    multiple bridges when necessary, instead of having the last bridge in
    the chain creating the connector and handling all connector operations
    internally.

mainline-commit:

f01195148967 2020-12-03 drm/mediatek: mtk_dpi: Create connector for bridges

When looking on the commit it seems that first line seems to break:

-	ret = drm_bridge_attach(&dpi->encoder, &dpi->bridge, NULL, 0);
+	ret = drm_bridge_attach(&dpi->encoder, &dpi->bridge, NULL,
+				DRM_BRIDGE_ATTACH_NO_CONNECTOR);
 	if (ret) {
 		dev_err(dev, "Failed to attach bridge: %d\n", ret);

I guess it’s related to the

 [drm:mtk_hdmi_bridge_attach] *ERROR* Fix bridge driver to make connector optional!

https://git.kernel.org/pub/scm/linux/kernel/git/chunkuang.hu/linux.git/tree/drivers/gpu/drm/mediatek/mtk_hdmi.c?h=mediatek-drm-next-5.12&id=f011951489678a9c679489136f5df064a86c84dd#n1311

But this seems to be fixed in 5.13,so there is another problem which breaks

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/gpu/drm/mediatek/mtk_hdmi.c#n1287

i tried to add only the new part which allows the current binding (not returning -EINVAL if flag is set), but then it fails later (i guess because connector is not added).

    drm/mediatek: Don't support hdmi connector creation

but i cannot apply the patch to the drm-next-5.12

tried now 5.12.14 which contains this fix too…and is also based on atomic patches…and this works…now i need a way to get the breaking commit between 5.12.14 and 5.13, but here i cannot do a bisect, but 5.13 resetted to this fix (2e4773915223) still do work…now i can do the bisect

while doing this i see multiple versions

  • be18cd1fcae2 shows warning about vblank timeout and purple screen without fbcon (like uboot for 1080p)
  • 01d713689441 do not show anything but also no crash/warning/backtrace
  • 16ae2044e91e same as above (no hdmi output but no traceback)
  • 2ba9bea2d368 same
  • 50eb842fe517 same, and i wonder why i see the “[drm:mtk_hdmi_bridge_attach] ERROR Fix bridge driver to make connector optional!” in dmesg as this should be shown no more as i set fix for this as good

my bisect log shows this:

and while running the bisect i do not see the fix-commit i defined as good at start…maybe this can be caused by merges?

restarted bisect and first (be18cd1fcae2) shows the backtrace

after defining this as bad (bisect stops at 01d7136894410a71932096e0fb9f1d301b6ccf07), the fix is no more included (but why???)

and i see another problem in 5.13: “watchdog: watchdog0: watchdog did not stop!” on reboot-command, but let us fix hdmi

Update july 9:

I have send the bug to mailinglist and it looks like a irq problem

http://lists.infradead.org/pipermail/linux-mediatek/2021-July/026583.html

Watchdog problem is caused by known commit in mtk_wdt.c and not related,wrote the author directly without mailinglist.

Update july 10:

Have found breaking commit and fixed it by adding back the missing function

https://patchwork.kernel.org/project/linux-mediatek/patch/[email protected]/

Fix is applied to my 5.13-main tree

@DeadMeat maybe this patch fixes 4k-problem?

Tested with 5.13-main - works both fb and Xorg.

Maybe you want to backport it to last stable (5.10)?

Ok, I’ve found the patch that is required for threshold calculation (4k patch).

Patched 5.10 has been successfully compiled, but not yet tested.

Commits are in my 5.10-main branch. I’ll update the post after testing.

Tested, not works. Probably it was not the main patch to fix 4k.

Further digging into the source.

maybe this?

6385ed8eaa02 2021-05-26 drm/mediatek: dpi: Add dual edge sample mode support

is 5.13 (5.12,5.11) working with the patch…just to get a smaller diff…there is many in drm done between 5.10 and 5.14

I’ve tried 5.14-main, works - confirmed.

I meant going back from 5.13 with the path to get latest version working. Juste to limit count of patches needed. E.g. if 5.13 works and 5.12 not you can get diff/log between these 2

Sure, just tested 4k while testing wifi on 5.14. From my experience :

  • -5.10-main and any prior has hdmi working but w/o 4k.
  • -5.11 - not tested.
  • -5.12-hnat(not tested on main) - hdmi broken (bridge error, not sure if already fixed in 5.12-main )
  • -5.13-main - hdmi fixed, 4k works with the patch( not tested w/o it), also needs Fix cursor plane patch(already included to main tree)
  • -5.14-main - Everything works.(I see rdma threshold patch is already included).

I need some time to tested 5.12 and/or 5.11

Bridge error was fixed in stable 5.12.x,afair i have merged dot-release to 5.12-main,but not rebased 5.12-hnat.

edit: added patches to 5.12-hnat to fix the bridge-error (not tested), 5.11 was working afair

tested with 5.12-hnat, bridge error fixed, but 4k TV doesn’t work both with or w/o adjust rdma fifo threshold patch.

Looks like the problem was resolved in 5.13.

Then it is a patch between 5.12 and 5.13…there are not much as between 5.10 and 5.13 :slight_smile:

This is the pull-request https://patchwork.kernel.org/project/linux-mediatek/patch/[email protected]/

This is the only looking related based on commit message:

dpi: Add check for max clock rate in mode_valid

Maybe ask dafna hirschfeld…

i tested with my 4k screen, and yes, 5.14 works.

got 5.13 working in fbdev, but not x-server with these patches on top of 5.12-hnat:

so i guess i only miss one/more of the atomic-patches, most of them cannot be applied due to many depencies

Sorry, i didn’t get if that was 5.13 or 5.12? In my case 5.13 needed patch for xorg cursor.

Tried 5.12-hnat…took patches from 5.13

have no mouse connected…only try to bootup into x-server with 4k-screen connected

Probably I’m doing smth wrong, but I can’t apply this patch(or i got wrong one):

Applying: dt-bindings: media: add pclk-sample dual edge property
error: patch failed: Documentation/devicetree/bindings/media/video-interfaces.txt:118
error: Documentation/devicetree/bindings/media/video-interfaces.txt: patch does not apply
Patch failed at 0001 dt-bindings: media: add pclk-sample dual edge property
hint: Use 'git am --show-current-patch=diff' to see the failed patch
When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".

Could you plz provide a link to it on patchwork?

You do not need the dtbindings-patch…only code-change. But at least xserver still don’t work

have pushed my 5.10-hnat and 5.12-hnat branch

I’ve tried your 5.12-hnat - not works for me, including fb:

5.12-hnat.4k.txt (6.1 KB)

The dmesg is pretty the same as yours. The TV screen is corrupted.
