Hello,
This is an addition to the series sent from Daniel Axtens
(https://lists.gnu.org/archive/html/grub-devel/2022-04/msg00064.html).
Patch 'ieee1275: request memory with ibm,client-architecture-support'
implements vectors 1-4 of client-architecture-support negotiation
However, during some tests, we found this can be a problem if:
- we have more than 64 CPUs
- Hardware Management Console (HMC) is configured to minimum of CPUs >64 (for
example, min of 200 CPUs)
- Grub needs to request memory.
If vector 5 is not implemented, Power Hypervisor will consider the default
value for vector 5 and 64 will bet set as the maximum
number of CPUs supported by the OS, causing the machine to fail to init.
Today we support 256 CPUs (max) on Power, so we need to implement vector 5 and
set the MAX CPUs bits to this value.
The patches 11-15 aren't merged to the grub tree yet, so I'm sending those
patches again together with my patch to implement vector 5
on top of them.
The patches 11-15 contains the following:
Daniel Axtens (4):
ieee1275: request memory with ibm,client-architecture-support
ieee1275: drop len -= 1 quirk in heap_init
ieee1275: support runtime memory claiming
[RFC] Add memtool module with memory allocation stress-test
Stefan Berger (1):
