Subject: [PATCH v2 11/13] gpu: nova-core: align LibosMemoryRegionInitArgument size to page size
Date: Mon, 1 Dec 2025 17:39:20 -0600	[thread overview]
Message-ID: <20251201233922.27218-12-ttabi@nvidia.com> (raw)
In-Reply-To: <20251201233922.27218-1-ttabi@nvidia.com>

GSP-RM insists that the 'size' parameter of the
LibosMemoryRegionInitArgument struct be aligned to 4KB.
