Hi,
I would like to announce the iSCSI enterprise target (IET) software,
which is open-source software to build iSCSI storage systems. It can
provide disk volumes to iSCSI initiators by using any kinds of files
(regular files, block devices, virtual block devices like RAID and
LVM, etc). The
.
Even if we revert the qla1280 patch, scsi-ml still sends chaining sg
list. So it doesn't work.
The following patch disables chaining sg list for qla1280. If the fix
that I've just sent doesn't work, please try this.

This depends on scsi-misc, the patchset, and sg chaining stuff.

iommu code merges sg lists without considering lld's restrictions so

The problem is that iommu code can't access to the restrictions

Unfortunately, that's what the sparc64

Except for sparc64, the IOMMU implementations do something like this,

IOMMUs merges scatter/gather segments without considering a low level

This sets the segment size limit properly via pci_set_dma_max_seg_size

Thanks.
Based on the presence of the call. 2.6.22, for instance, does not have

I did not test this change, just accepting on the principals. How much
testing of the change did you do Fujita?
This converts tgt to use the data buffer accessors to reduce the size

This patchset convert the PPC64 IOMMU to use the iova code for free
area management.
The IOMMUs ignores low level drivers' restrictions, the maximum
segment size and segment boundary.
I fixed the former:

The latter makes the free area management
iova could be used by several IOMMUs. This patch just moves iova from
drivers/pci/ to lib/ and fixes the appropriate Makefile and Kconfig
files.

This adds PCI's accessor for segment_boundary_mask in
device_dma_parameters.
The default segment_boundary is set to 0x, same to the block
layer's default value (and the scsi mid layer uses the same value).

This patch makes swiotlb not allocate a memory area spanning LLD's
segment boundary.
is_span_boundary() judges whether a memory area spans LLD's segment
boundary. If map_single finds such a area, map_single tries to find
the next available memory area.

This is the latter half of my iommu work to make the IOMMUs respect
LLDs restrictions.
IOMMUs allocate memory areas without considering a low level driver's
segment boundary limits. So we have some workarounds: splitting sg
segments again in LLDs; reserving all I/O space spanning 4GB boundary
