Subject: [Intel-gfx] [PATCH 06/11] drm/i915: Use i915_gem_context_get_eb_vm in ctx_getparam
Date: Fri, 13 Aug 2021 22:30:28 +0200 [thread overview]
Message-ID: <20210813203033.3179400-6-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20210813203033.3179400-1-daniel.vetter@ffwll.ch>
Consolidates the "which is the vm my execbuf runs in" code a bit. We
do some get/put which isn't really required, but all the other users
want the refcounting, and I figured doing a function just for this
getparam to avoid 2 atomis is a bit much.
