Subject: [PATCH v2 0/2] gpu: nova-core: gsp: fix misc cmdq issues
Date: Thu, 12 Nov 2026 15:14:52 +0900 [thread overview]
Message-ID: <20261112-msgq-64-pages-v2-0-bc1e6f7301ca@nvidia.com> (raw)
Fix two cmdq issues.
This is based on drm-rust-next.
Signed-off-by: Eliot Courtney <ecourtney@nvidia.com>

Changes in v2:
- Simplify the comment in patch #2 and check that `MSGQ_NUM_PAGES`
divides `1 << 32` (Alex). I used `%` since `is_multiple_of()` is out
due to MSRV.
- Add reviewed-by tags
- Link to v1: https://patch.msgid.link/20261111-msgq-64-pages-v1-0-d8c56b6fdd6c@nvidia.com
