From: Alyssa Rosenzweig Date: Mon, 25 Feb 2019 05:32:16 +0000 (+0000) Subject: panfrost: Import job data structures from v3d X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=59c9623d0a75d5201ad48351af26aad1bc0b7073;p=mesa.git panfrost: Import job data structures from v3d At the moment, Panfrost state is ad hoc, which creates issues for FBOs. This commit imports the skeleton of the v3d_job structure as panfrost_job, in preparation for refactors to organize this state.
