[Qemu-devel] [PATCH 0/8] sparc: IOMMU tidy-up and reorganisation


From: Mark Cave-Ayland
Subject: [Qemu-devel] [PATCH 0/8] sparc: IOMMU tidy-up and reorganisation
Date: Sun, 26 Nov 2017 13:35:18 +0000

Following on from the previous sun4u patchset, here is the next step of
IOMMU-related updates for 2.12.

This patchset does 2 main things: firstly it moves the sun4m IOMMU
device out of hw/dma and into hw/sparc to match existing architectures.
With this (and the previous sun4m DMA rework) the old sun4m.h header can
now be completely removed.

Secondly in a similar manner, we split the sun4u IOMMU functionality out
from the APB device into a new sun4u-iommu device in hw/sparc64, adding in
a conversion from DPRINTF macros to trace-events for good measure while
we are here.

Based-on: address@hidden ([PATCHv2 00/15] sun4u: tidy-up CPU, APB and ebus)


Mark Cave-Ayland (8):
  sun4m: move sun4m_iommu.c from hw/dma to hw/sparc
  sun4m: move IOMMU declarations from sun4m.h to sun4m_iommu.h
  sun4m: remove include/hw/sparc/sun4m.h and all references to it
  apb: QOMify IOMMU
  sun4u: split IOMMU device out from apb.c to sun4u_iommu.c
  sun4u_iommu: update to reflect IOMMU is no longer part of the APB
    device
  sun4u_iommu: convert from IOMMU_DPRINTF to trace-events
  sun4u_iommu: add trace event for IOMMU translations
