From: Oak Zeng Date: Wed, 5 Dec 2018 16:15:27 +0000 (-0600) Subject: drm/amdkfd: Init mqd managers in device queue manager init X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=fdfa090bc90f34543b8efd05b05a143ae6d52406;p=openwrt%2Fstaging%2Fblogic.git drm/amdkfd: Init mqd managers in device queue manager init Previously mqd managers was initialized on demand. As there are only a few type of mqd managers, the on demand initialization doesn't save too much memory. Initialize them on device queue initialization instead and delete the get_mqd_manager interface. This makes codes more organized for future changes.
