warhol (Xiaomi 17T Pro): source missing for 28 GPL-licensed kernel modules

[noahbliss]

Thank you for publishing the bsp-warhol-w-oss branches of MTK_kernel_device_modules and MTK_kernel_modules.

Comparing those branches with the kernel modules that ship on the device, 28 modules have no source in either branch. Each one declares MODULE_LICENSE("GPL") or MODULE_LICENSE("GPL v2") in its own .modinfo, so under GPLv2 section 3 their corresponding source should be available as well.

Device: Xiaomi 17T Pro (warhol), model 2602EPTC0G
Firmware: OS3.0.310.0.WPSMIXM (Android 16)
Kernel: 6.12.38-android16-5-g1d46253471dd-ab15048002-4k

Modules (file, where it ships, declared license):

• binder_gki.ko (vendor_dlkm, GPL)
• binder_prio.ko (vendor_dlkm, GPL)
• crash_module.ko (vendor_boot, GPL v2)
• dynamic_readahead.ko (vendor_boot, GPL v2)
• io_monitor.ko (vendor_boot, GPL v2)
• iorap2.ko (vendor_dlkm, GPL v2)
• kshrink_slabd.ko (vendor_boot and vendor_dlkm, GPL v2)
• metis.ko (vendor_dlkm, GPL)
• mi_mem_epoll.ko (vendor_dlkm, GPL)
• mi_memory.ko (vendor_boot, GPL)
• mi_mempool.ko (vendor_dlkm, GPL)
• mi_schedule.ko (vendor_dlkm, GPL)
• mi_thermal_interface.ko (vendor_dlkm, GPL v2)
• mi_unfairmem.ko (vendor_dlkm, GPL)
• miev.ko (vendor_boot, GPL)
• migt.ko (vendor_dlkm, GPL)
• millet_binder.ko (vendor_dlkm, GPL)
• millet_core.ko (vendor_dlkm, GPL)
• millet_hs.ko (vendor_dlkm, GPL)
• millet_oem_cgroup.ko (vendor_dlkm, GPL)
• millet_pkg.ko (vendor_dlkm, GPL)
• millet_sig.ko (vendor_dlkm, GPL)
• perf_helper.ko (vendor_boot and vendor_dlkm, GPL)
• powersave.ko (vendor_dlkm, GPL)
• simtray.ko (vendor_boot and vendor_dlkm, GPL)
• sla.ko (vendor_dlkm, GPL v2)
• xiaomi_spi_tee.ko (vendor_dlkm, GPL)
• xm_power.ko (vendor_dlkm, GPL)

Could you please publish the source for these modules, matching the version shipped in OS3.0.310.0.WPSMIXM, together with the Kbuild/Makefile/BUILD.bazel entries and headers needed to build them? Adding them to the existing bsp-warhol-w-oss branches would be ideal.

How this was checked: every .ko in the vendor_boot ramdisk and in vendor_dlkm was matched by name against the Kbuild, Makefile and Bazel files and the source file names in both branches. These 28 have no match. For miev, only the header include/miev/mievent.h is present, not the driver.

Thank you.

Checking the same thing against the JP retail build, 7 more modules have no source
in either branch. They are not in the list above, so adding them here.

Firmware: OS3.0.304.0.WPSJPXM (Android 16), same device and kernel
(Xiaomi 17T Pro / warhol / 2602EPTC0G, 6.12.38-android16-5-g1d46253471dd-ab15048002-4k)

• goodix_core_warhol.ko (vendor_dlkm, GPL)
• xiaomi_touch_warhol.ko (vendor_dlkm, GPL)
• hardwareinfo.ko (vendor_dlkm, GPL)
• hwid.ko (vendor_boot, GPL)
• mibbr.ko (vendor_dlkm, Dual BSD/GPL)
• minet.ko (vendor_dlkm, GPL)
• miwill.ko (vendor_dlkm, GPL)

The touch pair is the one I would ask for first: drivers/input/touchscreen/ in
bsp-warhol-w-oss ships GT9886/GT9895/GT9966 etc., but there is no xiaomi_touch
framework and nothing that builds goodix_core_warhol.ko or
xiaomi_touch_warhol.ko, which are the two modules the panel actually needs.
xiaomi_touch appears nowhere in the branch (0 hits over all paths).

Related, drivers/mihw/millet/ exists but contains only OWNERS, and the
matching block in drivers/mihw/Makefile was emptied out:

# MIUI ADD: Power_ProcessFreeze
# END Power_ProcessFreeze
# MIUI ADD: Cache_Prefetch
obj-y                                   += cache_prefetch/
# END Cache_Prefetch

so the millet modules in the list above are not just unbuilt, their directory was
stripped before publishing.

How this was checked: every .ko in vendor_dlkm and in the vendor_boot PLATFORM
ramdisk (545 modules) was matched by name against the file names, directory names
and the obj-* / *-objs entries of the Kbuild, Makefile and .mk files in both
bsp-warhol-w-oss branches. Licenses are from each module's own .modinfo.
