Copy back of per-slot error codes is only necessary for V2. V1 does not provide an error array, so copyback will unconditionally set the global rc to EFAULT. Only copyback for V2.

This series implements ballooning for Xen on ARM and builds and Mukesh''s PVH privcmd stuff to implement foreign page mapping on ARM, replacing the old "HACK: initial (very hacky) XENMAPSPACE_gmfn_foreign" patch. The baseline is a bit complex, it is basically Stefano''s xenarm-forlinus branch (commit bbd6eb29214e) merged with Konrad''s linux-next-pvh branch

This is with last night''s Xen snapshot (apr 24th), on kernel 2.6.12-rc3 - but the mess is so horrid that I''m not quite sure how to fix it... This oops prevents xen from starting xenU domains. Basically xend does the following: 1) mmap /proc/xen/privcmd 2) call an ioctl to populate the mmap 3) munmap the mapping created in (1) During the munmap, the dom0 kernel oopses, as

Hi Keir, I was encountering an odd error where Xend was tossing an EINVAL on xc_evtchn_alloc_unbound. After tracking it down, it turns out that this was because of an older userspace that was using the _compat version of the hypercalls. Since the hypervisor still supports these calls, is there a compelling reason to not allow privcmd to expose these calls? If not, please apply the

Hi all, In xen-4.1.2 source tree, under directory tools are there many library such lib*, what''s their individual feature? Besides, where is the log info for xl ? I try to trace using gdb after running xl, huge amounts of files\variable structure , complicated relationship between the components make me proceed slowly. Best regards

These mappings are in fact special and require special handling in privcmd, which already exists. Failure to mark the PTE as special on arm64 causes all sorts of bad PTE fun. x86 already gets this correct.

Hi Ian/Stefano, So, I''m back to using pfn space from maxphysaddr below. Stefano, you suggested ballooning, but that would be just too slow. There are lot of pages to be mapped, 4k at a time during guest creation, and I am afraid ballooning and hypercalls to populate EPT will be pretty slow. OTOH, there is tons of address space available between max-physaddr and max pfn in dom0. Stefano,

Hi, when creating a bigger (> 50 GB) HVM guest with maxmem > memory we get softlockups from time to time. kernel: [ 802.084335] BUG: soft lockup - CPU#1 stuck for 22s! [xend:31351] I tracked this down to the call of xc_domain_set_pod_target() and further p2m_pod_set_mem_target(). Unfortunately I can this check only with xen-4.2.2 as I don''t have a machine with enough memory for
