2026-05-16 bisect found linux-rk3588-marfrit @ f8f3ad9 black-screens ampere. The 6 patches in fleet/ampere.yaml includes apply cleanly on v7.0-rc3 mainline and produce a kernel that boots with working display + power-off. See commit message for full bisect notes.

No change to the includes list — same 6 patches as #8, just retargeted to a baseline they can actually be applied to.

Regression source still pending bisect; top suspect is 55d1b3dcc05e clk: rockchip: rk3588: Drop CLK_SET_RATE_PARENT from DCLK_VOP2_SRC.

fleet/ampere: pin baseline to torvalds v7.0-rc3 (working) instead of broken marfrit tip 62a6f88abd

2026-05-16 bisect found that linux-rk3588-marfrit @ f8f3ad9 (the
previous baseline.ref) black-screens ampere — eDP connector reports
connected/enabled/dpms On + SDDM starts + backlight on, but the panel
shows no pixels. Decomposing the suspend/resume patch 0010 into 5
atomic sub-commits and reverting all of them did NOT recover display,
ruling out 0010 as the offender.

The 6 patches already listed in fleet/ampere.yaml's includes apply
cleanly on top of v7.0-rc3 mainline and produce a kernel that boots
with working display + power-off. That's the verified-working baseline,
captured here.

Regression source is in one of the 12 remaining commits f8f3ad9 has on
top of v7.0-rc3. Top suspect: 55d1b3dcc05e "clk: rockchip: rk3588:
Drop CLK_SET_RATE_PARENT from DCLK_VOP2_SRC" (touches display
controller clock parent rate). Bisect campaign separately.

For consumers who want a ready-to-fetch ref instead of
patches-on-mainline, the verified-working tree is on
git.reauktion.de/marfrit/linux-rk3588-marfrit @ ampere-minimal-devices
(7c241f2e2835).

No change to the includes list — same 6 patches as #8, just retargeted
to a baseline they can actually be applied to.
