The kernel-level trigger is hardware-gated; per the DF-4857/DF-4858 convention for this driver family, verification is a verbatim userland replica run on this guest plus a fix compile of the real kernel module under -Werror. sys tree : /usr/src verified pristine against the audit tree before patching (rv740_dpm.c 98e600ce6e9b55011b16e2fe5a0302d8, irq_service_dce110.c 35607b1aeb1dc71fa3108f6573b6c5fd, irq_service.c 95266b5bed1212f931e08a5a129ad73c) and re-verified pristine after revert.
