From: Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx> We will later copy it to hvm_start_info. (Also remove stale comment claming that xc_dom_image.start_info_seg is only used for HVMlite guests) Signed-off-by: Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx> --- tools/libxc/include/xc_dom.h | 8 +++++++- tools/libxl/libxl_x86.c | 6 ++++++ 2 files changed, 13 insertions(+), 1 deletion(-) diff --git a/tools/libxc/include/xc_dom.h b/tools/libxc/include/xc_dom.h index 491cad8..6ef68f9 100644 --- a/tools/libxc/include/xc_dom.h +++ b/tools/libxc/include/xc_dom.h @@ -99,7 +99,7 @@ struct xc_dom_image { struct xc_dom_seg p2m_seg; struct xc_dom_seg pgtables_seg; struct xc_dom_seg devicetree_seg; - struct xc_dom_seg start_info_seg; /* HVMlite only */ + struct xc_dom_seg start_info_seg; xen_pfn_t start_info_pfn; xen_pfn_t console_pfn; xen_pfn_t xenstore_pfn; @@ -224,6 +224,12 @@ struct xc_dom_image { /* Extra SMBIOS structures passed to HVMLOADER */ struct xc_hvm_firmware_module smbios_module; + /* PVH guests */ +#if defined(__i386__) || defined(__x86_64__) + struct e820entry *e820; + unsigned int e820_entries; +#endif + xen_pfn_t vuart_gfn; }; diff --git a/tools/libxl/libxl_x86.c b/tools/libxl/libxl_x86.c index 3331cc5..0de278f 100644 --- a/tools/libxl/libxl_x86.c +++ b/tools/libxl/libxl_x86.c @@ -600,6 +600,12 @@ int libxl__arch_domain_construct_memmap(libxl__gc *gc, goto out; } + if (d_config->b_info.type == LIBXL_DOMAIN_TYPE_PVH) { + dom->e820 = libxl__malloc(gc, sizeof(struct e820entry) * e820_entries); + dom->e820_entries = e820_entries; + memcpy(dom->e820, e820, e820_entries * sizeof(*(dom->e820))); + } + out: return rc; } -- 1.8.3.1 _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxxx https://lists.xenproject.org/mailman/listinfo/xen-devel
