This series goes through x86 code to make CONFIG_HVM work. With this series, it is possible to build Xen with PV support only. Running `xl info` on a host with PV only Xen: root@lcy2-dt108:~# xl info host : lcy2-dt108 release : 4.17.0-0.bpo.1-amd64 version : #1 SMP Debian 4.17.8-1~bpo9+1 (2018-07-23) machine : x86_64 nr_cpus : 8 max_cpu_id : 7 nr_nodes : 1 cores_per_socket : 4 threads_per_core : 2 cpu_mhz : 3504.057 hw_caps : bfebfbff:77faf3ff:2c100800:00000121:0000000f:009c6fbf:00000000:00000100 virt_caps : hvm_directio total_memory : 32589 free_memory : 4158 sharing_freed_memory : 0 sharing_used_memory : 0 outstanding_claims : 0 free_cpus : 0 xen_major : 4 xen_minor : 12 xen_extra : -unstable xen_version : 4.12-unstable xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p xen_scheduler : credit xen_pagesize : 4096 platform_params : virt_start=0xffff800000000000 xen_changeset : Fri Aug 17 12:53:34 2018 +0100 git:382ad34e4e xen_commandline : placeholder loglvl=all guest_loglvl=all com2=115200,8n1 ucode=scan console=com2,vga console_to_ring sync_console hvm_fep cc_compiler : gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516 cc_compile_by : wei cc_compile_domain : uk.xensource.com cc_compile_date : Fri Aug 17 14:41:56 BST 2018 build_id : 3989ecb7693aa02f6ecc748a951ed444cc70ba94 xend_config_format : 4 The hvm_directio flag is not accurate. See the last patch for discussion. The major goal at the moment is to get something that works first, then refine code structure later. Currently CONFIG_HVM is littered in individual files. In the future some of the code could / should be moved to files under hvm/ for cleaner split. I ran some basic PV / PVSHIM VM life cycle tests and XTF PV tests, all worked. $ ls -l xen # PV only, non-debug -rwxrwxr-x 1 wei wei 1957436 Aug 17 15:32 xen $ ls -l xen # default build, non-debug -rwxrwxr-x 1 wei wei 2379388 Aug 17 15:39 xen The PV only Xen is ~17.8% smaller in size.
