Adding a new plane state will result in overhead for the plane during the atomic-commit step. For the test in drm_atomic_helper_check_crtc_state() to succeed, it is important that the CRTC has an enabled primary plane after the commit. Simply testing the CRTC state's plane_mask for a primary plane is sufficient. Note that the helper still only tests for an attached primary plane. Drivers have to ensure that the plane contains valid pixel information. v5: * fix commit description (Javier) v3: * test for a primary plane in plane_mask (Ville) v2: * remove unnecessary test for plane->crtc (Ville) * inline drm_atomic_get_next_plane_state() (Ville) * acquire plane lock before accessing plane->state (Ville) Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas Fixes: d6b9af1097fe ("drm/atomic-helper: Add helper drm_atomic_helper_check_crtc_state()") Cc: Thomas Zimmermann Cc: Jocelyn Falempe Cc: Maarten Lankhorst Cc: Maxime Ripard Cc: David Airlie Cc: Daniel Vetter Cc: dri-devel@lists.freedesktop.org Link: https://patchwork.freedesktop.org/patch/msgid/20221007124338.24152-2-tzimmermann@suse.de Signed-off-by: Sasha Levin --- drivers/gpu/drm/drm_atomic_helper.c | 10 +--------- 1 file changed, 1 insertion(+), 9 deletions(-) diff --git a/drivers/gpu/drm/drm_atomic_helper.c b/drivers/gpu/drm/drm_atomic_helper.c index 8bf41aa24068..6526d6ade04b 100644 --- a/drivers/gpu/drm/drm_atomic_helper.c +++ b/drivers/gpu/drm/drm_atomic_helper.c @@ -899,7 +899,6 @@ int drm_atomic_helper_check_crtc_state(struct drm_crtc_state *crtc_state, bool can_disable_primary_planes) { struct drm_device *dev = crtc_state->crtc->dev; - struct drm_atomic_state *state = crtc_state->state; if (!crtc_state->enable) return 0; @@ -910,14 +909,7 @@ int drm_atomic_helper_check_crtc_state(struct drm_crtc_state *crtc_state, struct drm_plane *plane; drm_for_each_plane_mask(plane, dev, crtc_state->plane_mask) { - struct drm_plane_state *plane_state; - - if (plane->type != DRM_PLANE_TYPE_PRIMARY) - continue; - plane_state = drm_atomic_get_plane_state(state, plane); - if (IS_ERR(plane_state)) - return PTR_ERR(plane_state); - if (plane_state->fb && plane_state->crtc) { + if (plane->type == DRM_PLANE_TYPE_PRIMARY) { has_primary_plane = true; break; } From patchwork Wed Dec 28 14:38:42 2022 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 8bit X-Patchwork-Submitter: Greg Kroah-Hartman X-Patchwork-Id: 13083043 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.4.0 (2014-02-07) on aws-us-west-2-korg-lkml-1.web.codeaurora.org Received: from gabe.freedesktop.org (gabe.freedesktop.org [131.252.210.177]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (No client certificate requested) by smtp.lore.kernel.org (Postfix) with ESMTPS id F161FC54EBD for ; Wed, 28 Dec 2022 16:22:55 +0000 (UTC) Received: from gabe.freedesktop.org (localhost [127.0.0.1]) by gabe.freedesktop.org (Postfix) with ESMTP id 0A86B10E1B8; Wed, 28 Dec 2022 16:22:54 +0000 (UTC) Received: from ams.source.kernel.org (ams.source.kernel.org [145.40.68.75]) by gabe.freedesktop.org (Postfix) with ESMTPS id 3843A10E3B2 for ; Wed, 28 Dec 2022 16:22:51 +0000 (UTC) Received: from smtp.kernel.org (relay.kernel.org [52.25.139.140]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (No client certificate requested) by ams.source.kernel.org (Postfix) with ESMTPS id 182BAB816F4; Wed, 28 Dec 2022 16:22:50 +0000 (UTC) Received: by smtp.kernel.org (Postfix) with ESMTPSA id 5A570C433D2; Wed, 28 Dec 2022 16:22:48 +0000 (UTC) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=linuxfoundation.org; s=korg; t=1672244568; bh=l6SZ1o3XablMRreE/05h9qlGf3szz8R5it9zAPOMn0Y=; h=From:To:Cc:Subject:Date:In-Reply-To:References:From; b=wXAUdFOM2Nh6pIocMHZ1Ur7MzWMg28W9WuIAgeToNieGRT65sReAmjT273Mg0vjT+ lTjjwiZZNPD2Bw626gAqETbtodeo5stHCce+YZsJhxi60fMD29d5NNqv9z783nydpf gti/00Md91d/uRGOipe47sFN2jD+0u16b5bgHRos= From: Greg Kroah-Hartman To: stable@vger.kernel.org Subject: [PATCH 6.0 0734/1073] fbdev: geode: dont build on UML Date: Wed, 28 Dec 2022 15:38:42 +0100 Message-Id: <20221228144347.960024744@linuxfoundation.org> X-Mailer: git-send-email 2.39.0 In-Reply-To: <20221228144328.162723588@linuxfoundation.org> References: <20221228144328.162723588@linuxfoundation.org> User-Agent: quilt/0.67 MIME-Version: 1.0 X-BeenThere: dri-devel@lists.freedesktop.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: Direct Rendering Infrastructure - Development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Sasha Levin , Andres Salomon , linux-fbdev@vger.kernel.org, Greg Kroah-Hartman , Helge Deller , Randy Dunlap , linux-um@lists.infradead.org, patches@lists.linux.dev, dri-devel@lists.freedesktop.org, linux-geode@lists.infradead.org, Richard Weinberger , Johannes Berg Errors-To: dri-devel-bounces@lists.freedesktop.org Sender: "dri-devel" From: Randy Dunlap [ Upstream commit 71c53e19226b0166ba387d3c590d0509f541a0a1 ] The geode fbdev driver uses struct cpuinfo fields that are not present on ARCH=um, so don't allow this driver to be built on UML.
