similar to: [PATCH] Fix SRAT check for discontig memory

That change converted the (wrong) assumption of contiguous nodes'' memory to a similarly wrong one of assuming discontiguous memory (i.e. each node having separate E820 table entries). The code ought to be able to deal with both, though, and I hope this change makes it so. Signed-off-by: Jan Beulich <jbeulich@novell.com> --- 2009-08-24.orig/xen/arch/x86/srat.c 2009-08-28

The attached tarball will generate a patch that integrates the APCI SRAT parser from linux-2.6.16.29 into Xen. To generate the patch, unpack the tarball and run ./numa.sh. -- Ryan Harper Software Engineer; Linux Technology Center IBM Corp., Austin, Tx (512) 838-9253 T/L: 678-9253 ryanh@us.ibm.com _______________________________________________ Xen-devel mailing list

If the domain''s NUMA node-affinity is being specified by the user/toolstack (instead of being automatically computed by Xen), we really should stick to that. This means domain_update_node_affinity() is wrong when it filters out some stuff from there even in "!auto" mode. This commit fixes that. Of course, this does not mean node-affinity is always honoured (e.g., a vcpu

All, We are pleased to announce the release of OCFS2 1.4.10-1 and OCFS2 tools 1.6.3-2 for Oracle Linux 5 Update 7 and higher and Redhat Enterprise Linux 5 Update 7 and higher. Oracle's Unbreakable Linux Network users who are subscribing to the "OCFS2 1.4 packages for Enterprise Linux 5" channel can upgrade to this release by running up2date. Red Hat's Enterprise Linux 5

Linus et al, Here are the ocfs2 updates for 2.6.35. There are two major changes. Mark added allocation reservations to our node-local allocators. This gets us much more contiguousness when many processes are growing files in parallel. On the other end of contiguousness, ocfs2 has had a major limitation since the beginning. When ocfs2 needs new inodes, it has always grown its metadata

Hello, I''m attempting to boot Xen 4.0.1 on a SuperMicro H8DGi-F motherboard and having not much luck. I can boot the 2.6.32.26 (or .27) kernels alone, but when I add Xen into the mix, I get consistent boot failure. I''ve tried Xen 4.0.1-release, 4.0.2-rc1-pre and 4.0.2-rc2-pre, all get the same failure. xen/next-2.6.37 works and boots great, but since netback isn''t

Hi List, i'd like to share with you what happened yesterday. Kernel 2.6.36.1 ocfs2-tools 1.6.3 (latest). I had an old OCFS2 partition created with a 2.6.32 kernel and ocfs2 tools 1.4.5. I unmounted all partitions on all nodes in order to enable discontig-bg. I then used tunefs to add discontig-bg, inline-data and indexed-dirs. During indexed-dirs tunefs segfaulted and since then, fsck

Hi Folks: I run into a problem when enabling Xen in next generation server platforms with Xen c/s is 21380. Xen reported "CPU Not responding" when booting up 32 CPUs( 2 sockets with 8 cores/16threads total). The log files belonging showed something wrong with APCI. So I added x2apic=0 in the xen grub line, but the symptom remained. However, Native RHEL5.5 can

But it is almost always better to add the export in the patch that actually uses it. The intention is much more clear that way. > Acked-by: "Rafael J.

?I wrote about this a couple months back.? George asked me to submit to the Xen developers list, but I never had the time due to work demands on getting the new server set up.? In my case, I had to use a different server.? The new motherboard/CPU had no issues with the second CPU.? If you turn off and unplug the second CPU, it will work.

We have an application that has many processing threads writing more than a billion files ranging from 2KB ? 50KB, with 50% under 8KB (currently there are 700 million files). The files are never deleted or modified ? they are written once, and read infrequently. The files are hashed so that they are evenly distributed across ~1,000,000 subdirectories up to 3 levels deep, with up to 1000 files
