For a while I''ve been intending to provide a better environment for PV baremetal guests. The current arrangements, based on newlib, take quite a bit of porting for many programs. My plan is to take the FreeBSD libc, and write a set of functions implementing the "system calls" in terms of facilities provided by the Xen PV environment, frontend drivers, etc. As part of this I

Hi Xen folks! I''ve faced with one strange thing in ARM version of Xen: when I use xc_map_foreign_bulk() to map some memory from domU to dom0, after unmap() for previous returned address - memory is not freed at all. Let''s look at call stack: xc_map_foreign() -> linux_privcmd_map_foreign_bulk() -> { addr = mmap(fd); ioctl(fd, IOCTL_PRIVCMD_MMAPBATCH_V2 );

From: Ben Cressey <bcressey@amazon.com> The commit "minios: refactor xenbus state machine" caused "/state" to be appended to the local value of nodename. Previously the nodename variable pointed to dev->nodename. The xenbus_rm() calls were not updated to reflect this change, and refer to paths that do not exist. For example, shutdown_blkfront() for vbd 2049 would

Keir, could you apply the attached implementation of grant tables for MiniOs (by Steven Smith). Cheers Gregor _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi Folks, I''m sorry to come with a so technical question, but I''m working out a port of XEN on ARM in the context of EmbeddedXEN project. I digged into miniOS and found something which seems strange to me: the build_pagetable() function in mm.c. This function aims at building up the additional page tables which were not allocated by the hypervisor during the domain construction
