Adds fleet/ampere.yaml manifest and 3 scope-tagged patches in
patches/board/coolpi-genbook/ for the linux-ampere-fourier kernel.
Baseline: mainline v7.0-rc3. Patch set is the verified-working
minimum after a 2026-05-16 bisect campaign:
0001 pwm15 pinctrl entries (rk3588 SoC dtsi)
0002 pwm-fan + thermal cooling cells (genbook dts)
0003 RK806 system-power-controller (cm5 module dtsi)
NOT included (intentionally):
- misc_patches/genbook/kernel/0010 family — suspend/resume +
wakeup WIP, leave out until Markus closes the thread
- 8 cherry-picks (Shawn Lin pcie3 phy, Cristian Ciocaltea
clk+dw-dp, Sebastian Reichel hdmirx, Pedro Alves) plus the
DTS commits (lid switch, USB-C PD, speaker) — one or more
of these black-screens ampere; offender not yet bisected
The linux-rk3588-marfrit branch tip (f8f3ad9, 18 commits ahead
of v7.0-rc3) produced a display regression on ampere
(connector/dpms/SDDM all positive software-side, panel actually
blank). Decomposing patch 0010 into 5 atomic sub-commits and
reverting all 5 (= test-arch-plus-pcie3 branch on
git.reauktion.de/marfrit/linux-rk3588-marfrit) did NOT fix the
regression, ruling out 0010. The ampere-minimal branch
(v7.0-rc3 + only the 3 patches above) boots clean with display
on ampere — confirming the offender is one of the 14 patches
left out here.
ampere-minimal branch on git.reauktion.de/marfrit/linux-rk3588-marfrit
@ 0ce6ef5d48f2 is the working baseline.

# 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.
