From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chris Wilson Subject: [PATCH 01/12] drm/i915: Unconditionally initialise the interrupt workers Date: Tue, 24 Apr 2012 22:59:41 +0100 Message-ID: <1335304792-17636-1-git-send-email-chris@chris-wilson.co.uk> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: Received: from fireflyinternet.com (smtp.fireflyinternet.com [109.228.6.236]) by gabe.freedesktop.org (Postfix) with ESMTP id 73A8A9F512 for ; Tue, 24 Apr 2012 15:01:00 -0700 (PDT) List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: intel-gfx-bounces+gcfxdi-intel-gfx=m.gmane.org@lists.freedesktop.org Errors-To: intel-gfx-bounces+gcfxdi-intel-gfx=m.gmane.org@lists.freedesktop.org To: intel-gfx@lists.freedesktop.org List-Id: intel-gfx@lists.freedesktop.org Rather than duplicate similar code across the IRQ installers, perform the initialisation of the workers upfront. This will lead to simpler teardown and quiescent code as we can assume that the workers have been initialised.
