From mboxrd@z Thu Jan 1 00:00:00 1970 From: Magnus Damm Date: Tue, 15 Dec 2015 12:02:12 +0000 Subject: [PATCH 00/06] iommu/ipmmu-vmsa: IPMMU multi-arch update Message-Id: <20151215120212.26216.61530.sendpatchset@little-apple> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: iommu@lists.linux-foundation.org Cc: laurent.pinchart+renesas@ideasonboard.com, geert+renesas@glider.be, linux-sh@vger.kernel.org, joro@8bytes.org, linux-kernel@vger.kernel.org, horms+renesas@verge.net.au, Magnus Damm iommu/ipmmu-vmsa: IPMMU multi-arch update [PATCH 01/06] iommu/ipmmu-vmsa: Remove platform data handling [PATCH 02/06] iommu/ipmmu-vmsa: Convert to dev_data [PATCH 03/06] iommu/ipmmu-vmsa: Break out utlb control function [PATCH 04/06] iommu/ipmmu-vmsa: Rework interrupt code and use bitmap for context [PATCH 05/06] iommu/ipmmu-vmsa: Break out 32-bit ARM mapping code [PATCH 06/06] iommu/ipmmu-vmsa: Drop LPAE Kconfig dependency These patches update the IPMMU driver with a few minor changes to support multiple architectures. With these patches applied the driver is known to compile without issues on 32-bit ARM, 64-bit ARM and x86_64. With the series applied the r8a7790 IPMMU still gets invoked when the modetest utility is used to display a test pattern on the VGA port driven by the DU device.
