latest pv_ops dom0 (2.6.29-rc6) crashes / unhandled page fault
Hello. log of the crashing boot process: http://pasik.reaktio.net/xen/pv_ops-dom0-debug/pv_ops-dom0-bootlog-14-xen331-linux-2.6.29-rc6-crash.txt 2.6.29-rc5 based pv_ops dom0 works on the same computer.. with the same Xen version. I tried with and without pci=nomsi. adding ''noapic'' doesn''t seem to help (I need that with 2.6.29-rc5 to make it work). Any ideas

pvops0 kernel 2.6.32.x still does not boot if x > 18, shouldn''t that be fixed for release of Xen 4.0.2/4.1
Hello Jeremy & Keir, sorry to be persistent, but the problem that pvops0 kernel 2.6.32.x still does not boot if x > 18 on my machines (and on many other machines, see this mailing list) is not solved yet. Shouldn''t this be a great focus of debugging and fixing? What is the point of having releases for 4.0.2 or 4.1 if I don''t have a dom0 kernel? The last time I tried

[PATCH] Arch-neutral balloon driver
Attached patch makes the balloon driver arch-neutral (compiles on ia64... look ma, no #ifdef''s!). Please apply to xen-unstable. One change should be eyeballed, line 257 in balloon.c, because phys_to_machine_mapping[pfn] is not identical to pfn_to_mfn (different by sign bit, should be OK?)

Xen with dom0 pvops on ultra-recent "git tip" kernel on x86_64
Hi everyone, I am very excited to see that dom0 pvops is finally coming close to working, so I wanted to give it a try. >From the description it was not clear to me which kernel to chose as base for the patches.hg, so I took the latest (that was ~ 2 weeks ago) kernel on git.kernel.org I could find (post-2.6.28 git tip at that point). I managed to more or less apply all of the patches in the

[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 == machine

acpidump crashes on some machines
Hi, we have some problems with acpidump running on Xen Dom0. On 64 bit Dom0 it will trigger the OOM killer, on 32 bit Dom0s it will cause a kernel crash. The hypervisor does not matter, I tried 4.1.3-rc2 as well as various unstable versions including 25467, also 32-bit versions of 4.1. The Dom0 kernels were always PVOPS versions, the problems starts with 3.2-rc1~194 and is still in 3.5.0-rc3.

[PATCH 00 of 38] xen: add more Xen dom0 support
Hi Ingo, Here''s the chunk of patches to add Xen Dom0 support (it''s probably worth creating a new xen/dom0 topic branch for it). A dom0 Xen domain is basically the same as a normal domU domain, but it has extra privileges to directly access hardware. There are two issues to deal with: - translating to and from the domain''s pseudo-physical addresses and real machine
