Running the leon3 with grsim fails due to the patch
bsp/sparc: Ensure that data cache snooping is enabled
It looks like cache snooping is disabled when it is ran for all
the tests. Where is this supposed to be set at with this change?
The simulator should set the right Cache Control Register settings. If this is
not the case, then AG should fix this in their simulator.
It is disabled at the point Jennifer checks it in the code. Is it not this
way on real hardware?
I am not doubting the possibility of a simulator bug. This is complex.
The simulator, boot loader or GRMON must setup the Cache Control Register
correctly. The bits in this register depend on the particular LEON
implementation, so it is easier to deal with it in the boot loader, etc.
