Switch to bitmap_zalloc() to show clearly what we are allocating.
Besides that it returns pointer of bitmap type instead of opaque void *.

Allowing IOMMU_DOMAIN_DMA type IOMMU domain to be allocated allows the
default_domain of an iommu_group to be set. This delegates device-domain
relationships to the generic IOMMU code.

The generic IOMMU code will allocate and attach a dma ops domain to each
device that comes online, replacing any lazy allocated domain. Removes
RMRR application at iommu init time as we won't have a domain attached
to any device. iommu.c will do this after attaching a device using

Hey,
This patchset moves IOMMU_DOMAIN_DMA iommu domain management to iommu.c.
This avoids the use of find_or_alloc_domain whose domain assignment is
inconsistent with the iommu grouping as determined by pci_device_group.
Patch 3 permits domain type IOMMU_DOMAIN_DMA to be allocated via the

If an IOMMU driver requires to know which IOMMU a domain is associated
to initialise a domain then it will do so in device_attach, before which
it is not safe to call iommu_ops.

Used by iommu.c before creating identity mappings for reserved ranges to
ensure dma-map-ops won't ever remap these addresses.

Hi,
It's hard for me to understand why do we remove the rmrr related
code in this patch.
And, now we have two places to hold a domain for a device: group and
dev->info. We can consider to optimize the use of per device iommu
arch data. This should be later work anyway.
More comments inline.
Hi James,
Very glad to see this. Thank you!
