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.
Currently GRSIM does not turn on snooping on run, so for now it has to
be set up by a boot loader. From the next GRSIM release, snooping will
be turned on when using "run".
