Subject: [PATCH 10/10] drm/todo: remove task for idr_init_base()
Date: Fri, 1 Jul 2022 21:02:27 +0200 [thread overview]
Message-ID: <20220701190227.284783-3-dakr@redhat.com> (raw)
In-Reply-To: <20220701190227.284783-1-dakr@redhat.com>
From: Danilo Krummrich <dakr@redhat.com>
All IDRs in the DRM core and drivers which are applicable for using
idr_init_base() over idr_init() should be set up to use a proper base in
order to avoid unnecessary tree walks.

-idr_init_base()
----------------
-
-DRM core&drivers uses a lot of idr (integer lookup directories) for mapping
-userspace IDs to internal objects, and in most places ID=0 means NULL and hence
-is never used. Switching to idr_init_base() for these would make the idr more
-efficient.
