Confused about start of day setup
Hi,
I hope I''m right here. If not then please point me in the right
direction.
My problem in short:
I have problems using (pinning, mmu_update) physical pages from
0x900000 to 0xB1000 usualy.
I''m writing my own little amd64 64bit toy kernel (based on Mini-OS as
starting point) for xen and I run into problems with the way the start
of day sets up the physical pages.

[PATCH 00/12] Xen arch portability patches (take 4)
Hi Jeremy.
According to your suggestion, I recreated patches for Ingo's x86.git tree.
And this patch series includes Eddie's modification.
Please review and forward them. (or push back to respin.)
Recently the xen-ia64 community started to make efforts to merge
xen/ia64 Linux to upstream. The first step is to merge up domU portion.
This patchset is preliminary for xen/ia64 domU linux

[PATCH] xen/grant-table: Refactor gnttab_[un]map_refs to avoid m2p_override
(This is a continuation of "[PATCH v9] xen/grant-table: Avoid m2p_override
during mapping")
The grant mapping API does m2p_override unnecessarily: only gntdev needs it,
for blkback and future netback patches it just cause a lock contention, as
those pages never go to userspace. Therefore this series does the following:

DMA not enabled in Xen Kernel?
I installed Xen using the binary release on debian sarge and got it to boot
no problem but when I check if dma is enabled with ''hdparm /dev/hda'' it''s
not.
I can''t enable it either with ''hdparm -d1 /dev/hda''. Says operation not
permited. Using my debian default kernel dma works just fine.
How can I enable dma with the Xen Kernel?
Thanks!

doubt on phys_to_machine_mapping
Hi all,
Can some one tell me where phys_to_machine_mapping is being
initialized for a domU having paging mode set to PG_translate.
I see that, populate_physmap() after calling __alloc_xen_heap_pages only
updates the machine_to_physmap but how is the mfn for the allocated page
being updated/set for phys_to_machine_mapping??
I see that phys_to_machine_mapping is a #defined to RO_MPT_VIRT_START

[patch] phys_to_machine_mapping alignment on x86_64
Hi,
At x86_64 linux domain, phys_to_machine_mapping,
pfn_to_mfn_frame_list_list, and pfn_to_mfn_frame_list should be
aligned to pagesize, but it can be misaligned now.
If they aren''t aligned to pagesize, it will cause fails while saving
the domain.
This patch fixed it.

[PATCH v8 0/19] enable swiotlb-xen on arm and arm64
Hi all,
this patch series enables xen-swiotlb on arm and arm64.
It has been heavily reworked compared to the previous versions in order
to achieve better performances and to address review comments.
We are not using dma_mark_clean to ensure coherency anymore. We call the
platform implementation of map_page and unmap_page.
We assume that dom0 has been mapped 1:1 (physical address ==

Dynamic blacklisting
Does anyone know of a script that can act as a
"helper" for Shorewall''s dynamic blacklist
capabilities?
Briefly said, I''d like to know if someone already
wrote a script/program that, e.g., parses log files
(/var/log/messages, etc) and picks up for example all
IP addresses that failed SSH login more than X times
and then executes a command such as

Illegal PV kernel pfm/pfn translations on PROT_NONE ioremaps
Hi,
On paravirt x86 (both 32- and 64-bit), since cset 13998:
http://xenbits.xensource.com/xen-unstable.hg?rev/13998
we translate all ptes from being mfn-based to pfn-based when the
hardware _PAGE_PRESENT bit is cleared. We do this for PROT_NONE pages,
which appear to the HV to be non-present, but which are special-cased in
the kernel to appear present (a different bit in the
