Add libxc helpers for XEN_DOMCTL_viommu_op. Now, it has one sub-command - create(): create a vIOMMU in Xen, given viommu type, register-set location and capabilities Signed-off-by: Chao Gao <chao.gao@xxxxxxxxx> Signed-off-by: Lan Tianyu <tianyu.lan@xxxxxxxxx> --- v4: - remove destroy() sub-command v3: - Remove API for querying viommu capabilities - Remove pointless cast - Polish commit message - Coding style --- tools/libxc/Makefile | 1 + tools/libxc/include/xenctrl.h | 3 +++ tools/libxc/xc_viommu.c | 51 +++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 55 insertions(+) create mode 100644 tools/libxc/xc_viommu.c diff --git a/tools/libxc/Makefile b/tools/libxc/Makefile index 9a019e8..7d8c4b4 100644 --- a/tools/libxc/Makefile +++ b/tools/libxc/Makefile @@ -51,6 +51,7 @@ CTRL_SRCS-$(CONFIG_MiniOS) += xc_minios.c CTRL_SRCS-y += xc_evtchn_compat.c CTRL_SRCS-y += xc_gnttab_compat.c CTRL_SRCS-y += xc_devicemodel_compat.c +CTRL_SRCS-y += xc_viommu.c GUEST_SRCS-y := GUEST_SRCS-y += xg_private.c xc_suspend.c diff --git a/tools/libxc/include/xenctrl.h b/tools/libxc/include/xenctrl.h index 8ade90c..69cf03f 100644 --- a/tools/libxc/include/xenctrl.h +++ b/tools/libxc/include/xenctrl.h @@ -2537,6 +2537,9 @@ enum xc_static_cpu_featuremask { const uint32_t *xc_get_static_cpu_featuremask(enum xc_static_cpu_featuremask); const uint32_t *xc_get_feature_deep_deps(uint32_t feature); +int xc_viommu_create(xc_interface *xch, domid_t dom, uint64_t type, + uint64_t base_addr, uint64_t cap, uint32_t *viommu_id); + #endif int xc_livepatch_upload(xc_interface *xch, diff --git a/tools/libxc/xc_viommu.c b/tools/libxc/xc_viommu.c new file mode 100644 index 0000000..a72b2f4 --- /dev/null +++ b/tools/libxc/xc_viommu.c @@ -0,0 +1,51 @@ +/* + * xc_viommu.c + * + * viommu related API functions. + * + * Copyright (C) 2017 Intel Corporation + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License, version 2.1, as published by the Free Software Foundation. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
