Subject: [PATCH V5 01/18] amdkfd: enlarge the hashtable of kfd_process
Date: Fri, 17 Oct 2025 16:42:05 +0800 [thread overview]
Message-ID: <20251017084222.54721-2-lingshan.zhu@amd.com> (raw)
In-Reply-To: <20251017084222.54721-1-lingshan.zhu@amd.com>
This commit enlarges the hashtable size of
kfd_process to 256, because of the multiple
contexts feature allowing each application
create multiple kfd_processes
