Subject: [PATCH 0/8] pseries/iommu: bug-fixes and cleanups for dynamic dma windows
Date: Wed, 11 May 2011 15:24:56 -0700 [thread overview]
Message-ID: <1305152704-4864-1-git-send-email-nacc@us.ibm.com> (raw)
This series of patches attempts to cleanup and fix some bugs related to
dynamic dma windows and kexec/kdump. They build on the three patches I
have submitted most recently:
powerpc: fix kexec with dynamic dma windows
http://patchwork.ozlabs.org/patch/94445/
pseries/iommu: restore iommu table pointer when restoring iommu ops
http://patchwork.ozlabs.org/patch/94909/
pseries/iommu: use correct return type in dupe_ddw_if_already_created
http://patchwork.ozlabs.org/patch/95184/
The full series has been successfully tested with kdump/kexec on pseries
machine.
Milton Miller (8):
pseries/iommu: add additional checks when changing iommu mask
pseries/iommu: remove ddw property when destroying window
pseries/iommu: find windows after kexec during boot
pseries/iommu: cleanup ddw naming
powerpc: override dma_get_required_mask by platform hook and ops
dma-mapping: add get_required_mask if arch overrides default
powerpc: use the newly added get_required_mask dma_map_ops hook
powerpc: tidy up dma_map_ops after adding new hook
