similar to: Kernel panic in DomU when using swiotlb=force option

Normal boot path on system with iommu support: swiotlb buffer will be allocated early at first and then try to initialize iommu, if iommu for intel or AMD could setup properly, swiotlb buffer will be freed. The early allocating is with bootmem, and could panic when we try to use kdump with buffer above 4G only, or with memmap to limit mem under 4G. for example: memmap=4095M$1M to remove memory

My Emails a week or so back were about installing Rstudio and the R shiny server on Debian. I was using an old Toshiba laptop as a sandbox for that and it would only install i386 (same for Ubuntu). Using the information at https://cran.r-project.org/bin/linux/debian/ I did get to the point where I had R 3.5.2, Rstudio and the server on there (with some help from Dirk that is in the list archives).

Hi, I have been using CentOS 4 on a UML (User-Mode Linux) box for some time (>1 year) and have kept up to date with updates. I think I started on CentOS 4.1 and have progressively "yum update"'d since. User-Mode Linux, or at least the version of it that my hosts use, doesn't support NPTL. This hasn't been a problem to date; I've just moved /lib/tls out of the way, as

Greetings, Box is i4790 w. GTX 980 running virgin master (.today).

I've posted this question to the Gnome users list, but so far no luck, so I thought I'd mention this here. A little while ago, I noticed that I was no longer able to log out from my GDM. I'm running the default GDM (2.16) that comes with CentOS, and this problem started up right about the same time that I updated to the 53.1.4 kernel (from the 8.1.15 version). As I've posted

Hi all, Sorry write to this list, here is the only place with a thread and a solution to this problem. At http://lists.xensource.com/archives/html/xen-devel/2007-09/msg00140.html you can read “ No, you simply don’t have a big enough swiotlb. The default is 2MB for a machine with less than 2GB of RAM, or 64MB for >2GB systems. “ All seen that for that guy that problem get solved changing the

Hi All, I have several ia32e systems with 8 gig that panic on install and first boot. The panic is arch/x86_64/swiotlb.c (working from memory so I might be a bit off) and its in the routine that I think is trying to allocate another chunk of memory for the "Software I/O Translation Buffer". I am guessing it needs to allocate contiguous chunks of memory and that is why it fails on the

Hi Jan, I''m curious about the status of your patches to make lib/swiotlb.c more Xen friendly. The ia64 port is currently using the hacked up swiotlb in the i386 directory, and it''s making it difficult to enable machine vectors to support hardware iommus. From what I can gather, several of the smaller patches are now in upstream Linux, but the larger abstraction patch got

The linux-2.6-xen tree has a typo in the Kconfig file for i386 that disables building swiotlb. This patch fixes it in the same manner that x86-64 does it.
