However, it works fine in KVM mode as hardware is generating the number. -Steps to reproduce: -1. load a short IDT e.g. with 64 entries -2. trigger a self IPI through the LAPIC with a vector 100 -3. the pushed error code is 802 instead of 803. -Additional information: -It can be fixed in the lines `raise_exception_err(env, EXCP0D_GPF, intno * 8 + 2);` in `seg_helper.c` -which must include the `is_hw` field when calculating the error number. Something like `intno * 8 + 2 + (is_hw != 0)` -works here. - -Nevertheless, all the other exception cases in the `do_interrupt_*` functions have to set the same bit as well. |
