The BADVA reg is referred to with the wrong identifier. The CAUSE reg field of SSR is not yet modeled, we will dump the SSR in a subsequent commit. Signed-off-by: Brian Cain <[email protected]>

To remove any confusion with HVX or other potential store instructions, we'll qualify this context var with "scalar". Signed-off-by: Brian Cain <[email protected]>

It's odd to have |
As specified by the PRM, we should raise an exception when a packet contains multiple writes to the same register. Lets introduce a bitmap at the CPUArchState, looking for writes to already written registers and properly generate an exception when needed. Also add a test case to tests/tcg/system. The added test shows a scenario in which multiple writes are performed to the same register but qemu fails to detect that and throw the appropriated exception. This happens because we are not cleaning hex_slot_cancelled as frequently as we should, so an old state is used and the packet that should raise an exception is considered as cancelled by the code that would detect the multiple writes issue. Let's fix that by cleaning hex_slot_canceled on all conditional instructions instead, which should cover all cases where the variable is used to detect multiple writes.

We should raise an exception in the event that we encounter a packet that can't be correctly decoded, not fault. Signed-off-by: Brian Cain <[email protected]>
