Hi,
In this version the biggest change is the end of the numa_assoc_array
struct in the machine state. The write_dt() functions are now retrieving
the current NUMA associativity array by checking CAS first.
This change allowed for several simplifications, e.g. we don't need
a reset() function to be called after CAS or in spapr_post_load().
Arrays are now statically allocated.
I also catched a last minute bug during my tests. See patch 7 for more
info.
Changes from v6:
- patch 1:
* added Greg's r-b
- patch 2:
* added the missing NUMA nodes number check
* added Greg's r-b
- patch 3 (former patch 4):
* no changes.
- former patch 3 (associativity_reset()): dropped
- patch 4 (new):
* added get_associativity()
* do not allocate FORM1_assoc_array in the heap
- patch 5:
* fixed typo
* added new check function to be called in CAS
- patch 6:
* do not allocate FORM2_assoc_array in the heap
- patch 7 (new):
* FORM2 fixes to handle the implicit added QEMU NUMA node when there's
no NUMA node added by the user.
