After verifying the minimal v7.0-rc3+pwm15+pwm-fan+RK806 baseline boots with display on ampere, extended via bisect-by-addition to include 3 more from linux-rk3588-marfrit's pre-cherry-pick set: 0004 enable speaker output (genbook dts + cm5 dtsi) 0005 USB-C PD charging (genbook dts: FUSB302, vcc5v0_otg) 0006 lid switch + USB3 lane mux (genbook dts: gpio-keys SW_LID, usbdp_phy1) ampere-minimal-devices branch on git.reauktion.de/marfrit/linux-rk3588-marfrit @ 7c241f2e2835 = the verified-working state with all 6 patches. Display continues to work — confirms regression source is in one of the 12 remaining linux-rk3588-marfrit commits (Shawn Lin pcie3 phy series, Cristian Ciocaltea clk/dts/dw-dp, Sebastian Reichel hdmirx, Pedro Alves btrtl, plus the WIP suspend/resume patch 0010).

# kernel-agent manifest for ampere (CoolPi GenBook / Rockchip RK3588)

#
|
|
# Status: minimal baseline established 2026-05-16 after the
|
|
# linux-rk3588-marfrit tip @ f8f3ad9 baseline produced a black-screen
|
|
# regression on ampere (display blank, software-state OK). Bisect
|
|
# narrowed the working baseline to mainline v7.0-rc3 + 3 settled
|
|
# patches: pwm15 pinctrl + pwm-fan thermal + RK806 system-power-controller.
|
|
#
|
|
# The suspend/resume + wakeup series (sleep fixes / patch 0010 family in
|
|
# misc_patches) is WORK-IN-PROGRESS and intentionally NOT included here
|
|
# until upstream-ready.

|

# Other linux-rk3588-marfrit commits (lid switch, USB-C PD, speaker,
|
|
# 8 cherry-picks from Shawn Lin / Cristian Ciocaltea / Sebastian Reichel
|
|
# / Pedro Alves) are also DEFERRED — one or more of them caused the
|
|
# black-screen regression and the offender hasn't been identified yet.
