Convert all packed structures in VSP1 to use it. The GCC documentation [0] describes this attribute as "the structure or union is placed to minimize the memory required". The Keil compiler documentation at [1] warns that the use of this attribute can cause a performance penalty in the event that the compiler can not deduce the allignment of each field. Careful examination of the object code generated both with and without this attribute shows that these structures are accessed identically and are not affected by any performance penalty. The structures are correctly aligned and padded to match the needs of the hardware already. This patch does not serve to make a decision as to the use of the attribute, but purely to clean up the code to use the kernel defined abstraction as per [2]. [0] https://gcc.gnu.org/onlinedocs/gcc/Common-Type-Attributes.html#index-packed-type-attribute [1] http://www.keil.com/support/man/docs/armcc/armcc_chr1359124230195.htm [2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/linux/compiler-gcc.h?h=v4.16-rc5#n92 Signed-off-by: Kieran Bingham Reviewed-by: Laurent Pinchart --- This patch had some lengthy discussion about the use of the packed attribute. In the end, after discussing further with Laurent, we decided that as no performance impact occurs on the VSP1 driver (object code generated is identical), and that as this attribute clearly marks structures which are read by the VSP1, we can just keep it. This patch neither adds, nor removes the attribute - but purely adapts to using the linux macro as defined at [2] to ensure that compiler specifics are abstracted out. And in particular I feel that __packed is cleaner than __attribute__((__packed__)) v2: - Remove attributes entirely v6: - Re-added the attributes (back to v1 of this patch) drivers/media/platform/vsp1/vsp1_dl.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/media/platform/vsp1/vsp1_dl.c b/drivers/media/platform/vsp1/vsp1_dl.c index 10a24bde2299..e4aae334f047 100644 --- a/drivers/media/platform/vsp1/vsp1_dl.c +++ b/drivers/media/platform/vsp1/vsp1_dl.c @@ -25,19 +25,19 @@ struct vsp1_dl_header_list { u32 num_bytes; u32 addr; -} __attribute__((__packed__)); +} __packed; struct vsp1_dl_header { u32 num_lists; struct vsp1_dl_header_list lists[8]; u32 next_header; u32 flags; -} __attribute__((__packed__)); +} __packed; struct vsp1_dl_entry { u32 addr; u32 data; -} __attribute__((__packed__)); +} __packed; /** * struct vsp1_dl_body - Display list body From patchwork Fri Aug 3 11:37:22 2018 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit X-Patchwork-Submitter: Kieran Bingham X-Patchwork-Id: 10554995 Return-Path: Received: from mail.wl.linuxfoundation.org (pdx-wl-mail.web.codeaurora.org [172.30.200.125]) by pdx-korg-patchwork-2.web.codeaurora.org (Postfix) with ESMTP id F35AD13BB for ; Fri, 3 Aug 2018 11:37:40 +0000 (UTC) Received: from mail.wl.linuxfoundation.org (localhost [127.0.0.1]) by mail.wl.linuxfoundation.org (Postfix) with ESMTP id DE43F2C0DE for ; Fri, 3 Aug 2018 11:37:40 +0000 (UTC) Received: by mail.wl.linuxfoundation.org (Postfix, from userid 486) id D26B82C281; Fri, 3 Aug 2018 11:37:40 +0000 (UTC) X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on pdx-wl-mail.web.codeaurora.org X-Spam-Level: X-Spam-Status: No, score=-7.9 required=2.0 tests=BAYES_00,MAILING_LIST_MULTI, RCVD_IN_DNSWL_HI autolearn=unavailable version=3.3.1 Received: from vger.kernel.org (vger.kernel.org [209.132.180.67]) by mail.wl.linuxfoundation.org (Postfix) with ESMTP id 88BDD2C0DE for ; Fri, 3 Aug 2018 11:37:40 +0000 (UTC) Received: (majordomo@vger.kernel.org) by vger.kernel.org via listexpand id S1727538AbeHCNde (ORCPT ); Fri, 3 Aug 2018 09:33:34 -0400 Received: from perceval.ideasonboard.com ([213.167.242.64]:50436 "EHLO perceval.ideasonboard.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1727193AbeHCNde (ORCPT ); Fri, 3 Aug 2018 09:33:34 -0400 Received: from localhost.localdomain (cpc89242-aztw30-2-0-cust488.18-1.cable.virginm.net [86.31.129.233]) by perceval.ideasonboard.com (Postfix) with ESMTPSA id 025CA1A80; Fri, 3 Aug 2018 13:37:34 +0200 (CEST) From: Kieran Bingham To: Laurent Pinchart , linux-renesas-soc@vger.kernel.org, linux-media@vger.kernel.org Cc: Kieran Bingham , Kieran Bingham Subject: [PATCH v6 03/11] media: vsp1: Rename dl_child to dl_next Date: Fri, 3 Aug 2018 12:37:22 +0100 Message-Id: <0444a36cb182f268eb7dfadd8ccab626cf033850.1533295631.git-series.kieran.bingham+renesas@ideasonboard.com> X-Mailer: git-send-email 2.17.1 In-Reply-To: References: In-Reply-To: References: Sender: linux-media-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-media@vger.kernel.org X-Virus-Scanned: ClamAV using ClamSMTP From: Kieran Bingham Both vsp1_dl_list_commit() and __vsp1_dl_list_put() walk the display list chain referencing the nodes as children, when in reality they are siblings.

These extended commands require their own dma memory areas for a header and body specific to the command type. Implement a command pool to allocate all necessary memory in a single DMA allocation to reduce pressure on the TLB, and provide convenient re-usable command objects for the entities to utilise.

The DSMR register is updated to set the ODEV flag on interlaced pipelines, thus defining an interlaced stream as having the ODD field located in the second half (BOTTOM) of the frame buffer.
