mthca use of dma_sync_single is bogus
It seems the problems running mthca in a Xen domU have uncovered a bug
in mthca: mthca uses dma_sync_single in mthca_arbel_write_mtt_seg()
and mthca_arbel_map_phys_fmr() to sync the MTTs that get written.
However, Documentation/DMA-API.txt says:
void
dma_sync_single(struct device *dev, dma_addr_t dma_handle, size_t size,
enum dma_data_direction direction)

A better fix for the blkdev merging bug

Okay, I''ve checked in a better fix for the blkdev merging bug, which
should work okay for all IDE and SC...

NV43 + PPC64 = :(
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I've been trying to get nouveau working on a Geforce 6600LE in a
dual-core G5 PowerMac system. For various reasons, it's not working.
The first problem I encountered was the lack of virt_to_bus on 64-bit
PPC. After talking to benh on IRC, I created the attached patch.
nouveau.ko can at least load on PPC64 now. :)
However, during X-server

Is there a way to map pv guest pseudo physical address into dom0?
Hi, all
I''m reading the code of QEMU''s virtio infrastructure (hw/virtio.c) and
Linux''s virtio driver (virtio_blk.c, virtio_net.c).
Virtio drivers utilize scatter gather infrastructure in the Linux
kernel. It stores the physical addresses in scatter list. In Xen''s hvm
case, QEMU can access guest address space with
cpu_physical_memory_map.
