Hello Simon,
currently we use sandbox virtual addresses in all ACPI tables. This means that an application started by the U-Boot sandbox consuming these tables will crash due to accessing invalid addresses.
Shouldn't the ACPI tables be migrated to use valid pointers?
The confusion arises due to the difference between addresses and pointers. If we store addresses in the ACPI tables, then things should work.
My approach has been to avoid using casts, but instead use map_sysmem() and mem_to_sysmem().
Which particular piece of code is wrong in this case?
Tables DSDT, XSDT, RSDP, FADT in the sandbox contain sandbox virtual addresses instead of pointers to real host memory.
All code referring to these tables should be changed.
Best regards
Heinrich
