fairydust (t8103/J293): external DP only works when connected at boot; re-plug leaves dcpext unpowered, and a live unplug can wedge it until reboot #667
Description
I know fairydust is provided as-is and unsupported. I'm reporting a consistent, reproducible hot-plug failure with logs, in case it's useful for the "cold and hot plug quirks" mentioned in the 6.19 progress report.
Setup
- MacBook Pro 13" M1 2020 (J293,
MacBookPro17,1) - Kernel: fairydust
ce9f2eba72c061a50b2d790450e90af3439d8c24(2026-09-08), built with asahi-alarm'slinux-asahi7.1.13 config (asahirel 3), release7.1.13-fairydust-ARCH, GCC 16.1.1, rustc 1.93.1. m1n1 1.6.1 with fairydust dtbs; uboot-asahi 2026.07.asahi2. - Userspace: Arch Linux ARM (Omarchy 4.0.3), Hyprland 0.56.2 (aquamarine), Mesa 26.2.2.
- Display: Kogan 40" 5K2K (KAMN40DQUCWA), 5120x2160@60, on a single USB-C cable into the DP-capable port (
typec1/atcphy1/ hpm0x3f). The monitor also supplies PD power and a USB 2.0 hub (Genesys 05e3:0608).
Works
- Connected at boot: DP-1 comes up at 5120x2160@60 every time (after ~2–3 s link bring-up; the monitor's USB hub enumerates ~7 s after
dcp_dptx_connect). - Unplug (live, or while suspended) is clean:
HPD removed,cb_hotplug() connected:0,dcp_dptx_disconnect; the compositor drops DP-1.
Fails (3/3 attempts)
- Live re-plug, same port, same cable, ~13 s after unplug.
- Re-plug while suspended (s2idle), with the lid opened afterwards.
- The earlier live re-plug in a previous boot.
In every failing case:
dcp_dptx_connect(port=0),DCPDP13Servicechannels are created,display HPD asserted,cb_hotplug() connected:1, valid_mode:1, and the compositor re-adds DP-1 at 5120x2160@60.- Then
IOMFB: swap_submit_dcp: swallowed swap … as fControllerPowerState is 0 for External Display(and "timings are not enabled"). - Every ~10 s:
[drm] *ERROR* flip_done timed out/commit wait timed outon CRTC, plane and DP-1 connector. The display stays black and the compositor's IPC starts timing out. - DPMS off/on of DP-1 doesn't recover. Unplugging recovers the rest of the desktop. Only a reboot with the display attached brings DP back.
Notable difference: at cold boot, set_digital_out_mode(color:73 timing:63) "5120x2160" succeeds (finished:8273, no error). On resume after re-plug, the same call logs nifiedPipeline.cpp:7465: set_digital_out_mode returned 80000104 just after dcp_poweron(), and the external controller never reaches power state 1. On a live re-plug, no set_digital_out_mode for the external DCP appears at all before the swallowed swaps.
Workaround found
Disabling the output in the compositor (Hyprland: hl.monitor({ output = "DP-1", disabled = true })) produces dcp_poweroff() done for the external DCP. Re-enabling it about a minute later gave dcp_poweron() and a successful set_digital_out_mode "5120x2160" (finished:8171, no error), and the display works. So a full DCP power cycle recovers the stuck state; a DPMS toggle does not. It seems the re-plug path doesn't power-cycle dcpext the way a disable/enable does.
Update 2026-11-06: a second, worse failure after a live unplug
Same kernel and setup. The disable/enable workaround above had brought DP-1 back (20:58:09, set_digital_out_mode finished:8257), and the cable was then pulled ~9 s later while DP-1 was active:
- 20:58:18:
crtc_atomic_check: disconnected but no modeset×4,cb_hotplug() connected:0, valid_mode:1,dcp_dptx_disconnect(port=0). Shortly before that, DCP's syslog hadDPTXController::handleInterrupt(): FIFO error interrupt COMMON_INT_STA_3=0x00000010. - 21:03:47:
apple-drm soc:display-subsystem: PM: dpm_run_callback(): platform_pm_suspend returns -22(system suspend fails). - No
dcp_poweroff()for 271c00000.dcp after that, and none of the later re-plugs (22:09, 22:11, 22:15, 22:36) leads to adcp_poweron()or modeset. Each one showsdcp_dptx_connect,HPD asserted,cb_hotplug() connected:1, valid_mode:0, nr_modes:12, and by 22:36AFK[ep:28]: too many enabled services!andexpected announce but got 0xc0 on channel 49/51. - The compositor sees DP-1 with its modes, but every atomic commit, including
ATOMIC_TEST_ONLYwithALLOW_MODESET, fails with-EINVAL, and the kernel logs nothing. Disabling and re-enabling the output (the earlier workaround) doesn't help, because the DCP never powers off or on.
My reading of the source (not verified with a trace): the only -EINVAL path in dcp_crtc_atomic_check() that doesn't log is if (dcp->crashed). crashed is set without a message when a swap doesn't complete within 50 ms (iomfb_template.c, around the wait_for_completion_timeout(&cookie->done, msecs_to_jiffies(50)) in the swap-clear path). Nothing clears it, so only a reboot recovers. If that's right, a log line when crashed is set (and possibly a recovery path on the next hotplug) would make this much easier to diagnose. Disabling the output before unplugging, so the DCP powers off first, avoids it as far as I can tell.
Note: these logs are from fairydust ce9f2eba (2026-09-08). I see the branch has moved a lot since (head 432e09dc, 2026-11-05). I'm happy to rebuild on the current head and retest if that's more useful.
