ci(nightly): add modinfo/depmod, sparse, and qemu-insmod jobs#54
Merged
Conversation
Extends the nightly compile matrix with runtime + static validation on top of the existing kernel API compile check. - compile job: runs modinfo + depmod -n on every .ko after the build. Validates module metadata (license, version, USB id table, vermagic, parameters) and confirms dependency wiring is sane. - static-analysis job (8 cells, one per driver): runs sparse over the driver source with kernel 6.12 LTS headers. Cheap signal on common C bugs the kernel build doesn't fail on. Warnings don't currently fail the job; tightening to come once the baseline is established. - qemu-insmod job (8 cells, one per driver): builds a tinyconfig bzImage (kernel 6.12.30) with wireless + INET/ACPI/PCI/USB, packages a busybox initramfs with the .ko, and boots it under QEMU. The init script insmod-s the module and prints DRIVER_INSMOD_RESULT=0 on success, then 'reboot -f' triggers qemu's -no-reboot to exit cleanly. Catches NULL derefs in module_init, EXPORT_SYMBOL mismatches that modpost-with-empty- Module.symvers can't see, etc. Single kernel target (per-kernel bzImage builds would be hours each); revisit when we have a faster path. summary job now requires all three (compile, static-analysis, qemu-insmod) green to call the run successful.

static-analysis job (8 cells, one per driver): runs sparse over the driver source with kernel 6.12 LTS headers. Cheap signal on common C bugs the kernel build doesn't fail on. Warnings don't currently fail the job; tightening to come once the baseline is established.
qemu-insmod job (8 cells, one per driver): builds a tinyconfig + WiFi-enabled bzImage (kernel 6.12.30), a busybox initramfs carrying the .ko, and boots it under QEMU. The init script insmod-s the module and prints DRIVER_INSMOD_RESULT=0 on success. Catches NULL derefs in module_init paths, EXPORT_SYMBOL mismatches that modpost-with-empty-Module.symvers can't see, etc. Single kernel target (per-kernel bzImage builds would be hours each); revisit when we have a faster path.

Temporary pull_request trigger on this workflow so this PR exercises the new jobs end-to-end; that trigger will be reverted before merge.
