Subject: [PATCH v2 0/3] gpu: nova-core: fb: Hopper sysmem flush fix and cleanups
Date: Wed, 10 Jun 2026 18:18:58 -0700 [thread overview]
Message-ID: <20260611011901.84517-1-jhubbard@nvidia.com> (raw)
Changes in v2:
* Split the original single patch into two: a no-functional-change
patch that makes the GB20x FBHUB0 flush registers absolute, followed
by the Hopper fix.
* Made the FBHUB0 registers absolute instead of relative to a register
base window, per Alexandre Courbot's review.
* Dropped the "clean up FSP FRTS comments" patch, because it has already
been applied to drm-rust-next.
* Added a third patch with two tiny readability cleanups: compose the
Blackwell flush address as (hi << 32) | lo, and drop a duplicated
SysmemFlush doc link.
John Hubbard (3):
gpu: nova-core: Blackwell: use absolute FBHUB0 flush registers
gpu: nova-core: Hopper: use correct sysmem flush registers
gpu: nova-core: fb: two tiny readability cleanups
