The user can pass -device ioh3420,aer_log_max=0xffff and until now would be automatically modified to PCIE_AER_LOG_MAX_DEFAULT -> 15, from now on he will fail. However the behavior change is OK. > - /* clip down the value to avoid unreasobale memory usage */ > if (dev->exp.aer_log.log_max > PCIE_AER_LOG_MAX_LIMIT) { > return -EINVAL; > } If you already started working on it, maybe you can fix the error message when the user passes aer_log_max over PCIE_AER_LOG_MAX_LIMIT. For the moment we get: qemu-system-x86_64: -device ioh3420,aer_log_max=0xfff: Device initialization failed And I would suggest a more clear patch subject.

log_max have no chance to be PCIE_AER_LOG_MAX_UNSET, unless user specify it. Bonus: 1. remove unnecessary local variable. 2. fix a typo.
