Subject: Re: [Intel-gfx] [RFC-v23 00/13] Introduce Intel PXP component - Mesa single session
Date: Sat, 23 Jan 2021 16:18:45 +0200 [thread overview]
Message-ID: <afa3b62b-a625-21a4-6f28-66087b7283dd@intel.com> (raw)
In-Reply-To: <20210119074320.28768-1-sean.z.huang@intel.com>
Hi,
One of the thing that came up during UMD review is that the default
session ID is actually uAPI :
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/8064#note_776201
Could we expose it through a get_param on the context?
Thanks,
-Lionel
