Modules r2 for ./build.sh (adds the SOF HDA machine driver: sound on laptops with digital mics)

Kernel modules for kernel #33 (6.18.21-gbos-whl+), same as v32 plus snd-soc-skl_hda_dsp (SND_SOC_INTEL_SKL_HDA_DSP_GENERIC_MACH). Fixes no sound / no Bluetooth audio on SOF machines such as the Dell Latitude 7391 (issue #1). sha256 8d05757c6dcd531d34fd7b86ee1c5fc4c957abee491fc8185b8fb133a68a4370

Firmware r4 for ./build.sh (everything the kernel's drivers ask for)

Same layout as v34, but built from every firmware name the shipped kernel modules request (MODULE_FIRMWARE) plus the families whose names are built at run time: AMD GPUs (amdgpu), Realtek Ethernet/USB-Ethernet (rtl_nic: r8169, r8152), all Realtek Wi-Fi/Bluetooth (rtw88, rtw89, rtl_bt), Qualcomm Wi-Fi/Bluetooth (ath10k, ath11k, ath12k WCN7850, qca), Broadcom/Cypress, MediaTek Wi-Fi/Bluetooth, Intel Xe GPU, Intel ISH, all Cirrus amplifier tuning, and the WHENCE link names (e.g. intel/ibt-0040-1050). linux-firmware 12dfe670, sof-bin 2026.09.2. Kernel modules stay in v32. ./build.sh fetches this automatically.

Firmware r3 for ./build.sh (adds Intel Bluetooth link names)

Same as v33 plus intel/ibt-0040-1050, -2120 and -4150 (.sfi/.ddc): firmware names that linux-firmware defines only as WHENCE Link entries. Fixes Bluetooth on Intel AX201 laptops (e.g. Acer Aspire Lite AL15-52: "Failed to load Intel firmware file intel/ibt-0040-1050.sfi (-2)"). Kernel modules stay in v32. ./build.sh fetches this automatically.

Firmware r2 for ./build.sh (adds Realtek RTL8852 Wi-Fi)

Same as v32 plus rtw89 firmware for RTL8852A/B/BT/C and RTL8851B (v32 shipped none, so RTL8852BE laptops had no Wi-Fi). Kernel modules stay in v32. ./build.sh fetches this automatically.

Kernel #32: modules and firmware for ./build.sh

Prebuilt inputs for the one-command build (./build.sh downloads these):

• gbos86-modules-6.18.21-gbos-whl.tar.xz: the ~400 kernel modules built for kernel #32 (6.18.21-gbos-whl+), indexed with depmod. Built from this repo's kernel/ sources.
• gbos86-firmware-d5455717-sof2026.09.2.tar.xz: trimmed linux-firmware (d5455717) and sof-bin 2026.09.2 for Intel/Realtek/MediaTek/Qualcomm/Broadcom Wi-Fi and Bluetooth, i915, SOF audio.
