Subject: [PATCH 0/5] ppc/pnv: fix Homer/Occ mappings on multichip systems
Date: Tue, 19 Nov 2019 23:20:51 +0530 [thread overview]
Message-ID: <20191119175056.32518-1-bala24@linux.ibm.com> (raw)
Hi All,
PowerNV fails to boot in multichip systems due to some misinterpretation
and mapping in Homer/Occ device models, this patchset fixes the
following,
- Homer size is 4MB per chip and Occ common area size is 8MB
- Bar masks are used to calculate sizes of Homer/Occ in skiboot so
return appropriate value
- Occ common area is in BAR 3 on Power8 but wrongly mapped to BAR 2
currently
- OCC common area is shared across chips and should be mapped only once
for multichip systems
Request for your review and suggestions to make it better. I would like to
thank Cedric for his time and help to figure out the issues.
