Kernel config notes for distros

Your kernel configuration will need to include the Asahi-specific drivers. As of linux-asahi-6.6-14, this list is:

CONFIG_ARCH_APPLE=y
CONFIG_ARM64_MEMORY_MODEL_CONTROL=y
CONFIG_APPLE_AIC=y
CONFIG_APPLE_WATCHDOG=y
CONFIG_APPLE_DART=y
CONFIG_APPLE_SART=y
CONFIG_APPLE_PLATFORMS=y
CONFIG_APPLE_MBOX=y
CONFIG_APPLE_RTKIT=y
CONFIG_APPLE_RTKIT_HELPER=y
CONFIG_APPLE_SMC=y
CONFIG_APPLE_SMC_RTKIT=y
CONFIG_APPLE_PMGR_PWRSTATE=y
CONFIG_APPLE_PMGR_MISC=y
CONFIG_I2C_APPLE=y
CONFIG_NVME_APPLE=y
CONFIG_PCIE_APPLE=y
CONFIG_PINCTRL_APPLE_GPIO=y
CONFIG_PWM_APPLE=y
CONFIG_SPI_APPLE=y
CONFIG_SPMI_APPLE=y
CONFIG_GPIO_MACSMC=y
CONFIG_ARM_APPLE_SOC_CPUFREQ=y
CONFIG_APPLE_ADMAC=y
CONFIG_APPLE_M1_CPU_PMU=y
CONFIG_COMMON_CLK_APPLE_NCO=y
CONFIG_ARM_APPLE_CPUIDLE=y
CONFIG_TOUCHSCREEN_APPLE_Z2=m
CONFIG_INPUT_MACSMC_HID=y
CONFIG_POWER_RESET_MACSMC=y
CONFIG_CHARGER_MACSMC=y
CONFIG_MFD_APPLE_SPMI_PMU=y
CONFIG_VIDEO_APPLE_ISP=m
CONFIG_DRM_ASAHI=y
CONFIG_DRM_ADP=m
CONFIG_DRM_APPLE=m
CONFIG_SND_SOC_APPLE_MACAUDIO=m
CONFIG_SND_SOC_APPLE_MCA=m
CONFIG_SND_SOC_CS42L84=m
CONFIG_SPI_HID_APPLE_OF=y
CONFIG_HID_DOCKCHANNEL=m
CONFIG_BT_HCIBCM4377=m
CONFIG_RTC_DRV_MACSMC=y
CONFIG_APPLE_DOCKCHANNEL=y
CONFIG_PHY_APPLE_ATC=m
CONFIG_PHY_APPLE_DPTX=m
CONFIG_NVMEM_SPMI_MFD=y
CONFIG_MUX_APPLE_DPXBAR=m
CONFIG_NVMEM_APPLE_EFUSES=y

(Distros intending to support other platforms with their 16k arm64 kernel besides Apple Silicon will be inclined to build as many of these drivers as modules as they can. This is fine, though from a reliability standpoint building NVME_APPLE and SPI_HID_APPLE_OF in-kernel has worked much better for me.)

You should also double-check that you have the following configuration options set:

CONFIG_RUST=y
# CONFIG_GCC_PLUGINS is not set

CONFIG_UCLAMP_TASK_GROUP=y
CONFIG_SUSPEND=y
# CONFIG_HIBERNATION is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_SCHEDUTIL=y
CONFIG_ENERGY_MODEL=y
CONFIG_SERIAL_SAMSUNG=y
CONFIG_SERIAL_SAMSUNG_CONSOLE=y
CONFIG_REGULATOR_FIXED_VOLTAGE=y
CONFIG_WATCHDOG_HANDLE_BOOT_ENABLED=y
# CONFIG_DRM_ASAHI_DEBUG_ALLOCATOR is not set
CONFIG_DRM_FBDEV_EMULATION=y
CONFIG_DRM_SCHED=y
# CONFIG_DRM_VGEM is not set
CONFIG_DRM_GEM_SHMEM_HELPER=y
CONFIG_SND_SOC_CS42L83=m
CONFIG_SND_SOC_TAS2764=m
CONFIG_SND_SOC_TAS2770=m
CONFIG_HID_BATTERY_STRENGTH=y
CONFIG_HID_APPLE=m

Warning: if this is your first time modifying a kernel configuration, please do take the advice at the top of the file about not hand-editing the file seriously. Do NOT just copy the fragments in this wiki into your config and try to build the kernel; this is likely to result in an inconsistent config and a failed build. Instead, use the make menuconfig or make xconfig system to modify your kernel configuration.

For a reference kernel configuration, see here.
