Subject: [PATCH 0/6] gpu: nova-core: add GA100 support
Date: Fri, 10 Apr 2026 15:37:16 -0500	[thread overview]
Message-ID: <20260410203722.1586938-1-ttabi@nvidia.com> (raw)

GA100 is an odd GPU.  Architecturally, it's an Ampere.  However, it
uses the same GSP-RM boot process as a Turing.  It's VBIOS, for whatever
reason, has an IFR header that precedes the PCI ROM header and must
be skipped.  In addition, the FRTS window size must be set to 0 just
because it's a GA100.

So add all the missing code that GA100 needs to be supported.  There was
some infrastructure already for GA100 (e.g. the FbHal), but it was
incomplete.

Timur Tabi (6):
  gpu: nova-core: use correct fwsignature for GA100
  gpu: nova-core: do not consider 0xBB77 as a valid PCI ROM header
    signature
  gpu: nova-core: only boot FRTS if it actually exists
  gpu: nova-core: add FbHal::frts_size() for GA100 support
  gpu: nova-core: skip the IFR header if present
  gpu: nova-core: enable GA100
