similar to: [PATCH 0/2] Add hugetlb support for PV

This patch enables support of hugepages in a pv Xen environment. It is against the latest xen unstable tree on http://xenbits.xensource.com. The patch assumes the guest is passing a physically aligned hugepage. It does reference counting on all the underlying pages.

This is the latest version of a patch that adds hugepage support to the Xen hypervisor in a PV environment. It is against the latest xen-unstable tree on xenbits.xensource.com. I believe this version addresses the comments made about the previous version of the patch. Hugepage support must be enabled via the hypervisor command line option "allowhugepage". It assumes the guest

The PV superpage mapping feature has been in the hypervisor for a while now, but I''m not away of any use of this feature by an upstream guest kernel (e.g., and primarily of interest, pv_ops Linux). Am I mistaken, or is anyone looking into or interested in this? If the feature is unused we should remove it from the hypervisor in this development cycle, as it''s untested and is

hi, I tried to make huge page request in Fedora x86_64 PV guest using xen 4.1 unstable and it crashed(crash info given below) I had enabled superpages in config file I had also set hugepages parameter at boot time for the PV Dom U By excuting # cat /proc/mem_info | grep Huge gave me that there are 10 free huge pages available , still the domain crashed. [ 86.403654] BUG: unable to handle

Another option might be g95 instead of gfortran. I haven't used it for a while, but I seem to recall it working fine in gcc 4.0.1.

I'm having troubles running the test suite on OS X 10.4. Inside my objdir, 'make check' gives this: % make check llvm[0]: Running test suite

OK, I noticed a few problems with my previous email, so I will boil the question down: What I want to do is compile for x86 and ia64 from darwin. I also want to load my own passes into opt and llc. Should I be using llvmc at all here, or should I be doing something like llvmgcc -> gccas -> opt -> llc ? I've given up on the filetype=obj argument, so now the problem is that llc is

Hi, the idea of a dragon theme reminded me of the dragon-like serpents called "Nāga" from Cambodian mythology, among other places. Here's a brief link explaining the specific Cambodian meaning - http://en.wikipedia.org/wiki/Naga_(mythology)#N.C4.81gas_in_Cambodia I like this as a name, because it's unique short and easy to type and remember (as long as you omit the accent,

OK, that explains it. I probably didn't have runtest installed the last time I ran configure, and re-syncing with CVS also caused it to reconfigure, solving the problem but confusing me.
