xen: remove CONFIG_XEN_COMPAT, purge Xen 3.0 compatibility This overlaps the purpose of __XEN_INTERFACE_VERSION__. Remove Xen 3.0.2 compatibility. __XEN_INTERFACE_VERSION__ has compatibility to Xen 3.2.8 enabled. As Xen 3.3 was released almost 15 years ago, it seems unlikely anyone hasn't updated.

xen: purge no longer used hypervisor functions HYPERVISOR_poll(), HYPERVISOR_block(), and HYPERVISOR_crash() appear no longer used. Further get_system_time() appears to have disappeared at some point in the past, so HYPERVISOR_poll() was broken anyway. No functional change intended. Reviewed by: royger

xen: switch to use headers in contrib These headers originate with the Xen project and shouldn't be mixed with the main portion of the FreeBSD kernel. Notably they shouldn't be the target of clean-up commits. Switch to use the headers in sys/contrib/xen. Reviewed by: royger

xen/privcmd: implement the dm op ioctl Use an interface compatible with the Linux one so that the user-space libraries already using the Linux interface can be used without much modifications. This allows user-space to make use of the dm_op family of hypercalls, which are used by device models. Sponsored by: Citrix Systems R&D

xen: Code cleanup and small bug fixes xen/hypervisor.h: - Remove unused helpers: MULTI_update_va_mapping, is_initial_xendomain, is_running_on_xen - Remove unused define CONFIG_X86_PAE - Remove unused variable xen_start_info: note that it's used inpcifront which is not built at all - Remove forward declaration of HYPERVISOR_crash xen/xen-os.h: - Remove unused define CONFIG_X86_PAE - Drop unused helpers: test_and_clear_bit, clear_bit, force_evtchn_callback - Implement a generic version (based on ofed/include/linux/bitops.h) of set_bit and test_bit and prefix them by xen_ to avoid any use by other code than Xen. Note that It would be worth to investigate a generic implementation in FreeBSD. - Replace barrier() by __compiler_membar() - Replace cpu_relax() by cpu_spinwait(): it's exactly the same as rep;nop = pause xen/xen_intr.h: - Move the prototype of xen_intr_handle_upcall in it: Use by all the platform x86/xen/xen_intr.c: - Use BITSET* for the enabledbits: Avoid to use custom helpers - test_bit/set_bit has been renamed to xen_test_bit/xen_set_bit - Don't export the variable xen_intr_pcpu dev/xen/blkback/blkback.c: - Fix the string format when XBB_DEBUG is enabled: host_addr is typed uint64_t dev/xen/balloon/balloon.c: - Remove set but not used variable - Use the correct type for frame_list: xen_pfn_t represents the frame number on any architecture dev/xen/control/control.c: - Return BUS_PROBE_WILDCARD in xs_probe: Returning 0 in a probe callback means the driver can handle this device. If by any chance xenstore is the first driver, every new device with the driver is unset will use xenstore. dev/xen/grant-table/grant_table.c: - Remove unused cmpxchg - Drop unused include opt_pmap.h: Doesn't exist on ARM64 and it doesn't contain anything required for the code on x86 dev/xen/netfront/netfront.c: - Use the correct type for rx_pfn_array: xen_pfn_t represents the frame number on any architecture dev/xen/netback/netback.c: - Use the correct type for gmfn: xen_pfn_t represents the frame number on any architecture dev/xen/xenstore/xenstore.c: - Return BUS_PROBE_WILDCARD in xctrl_probe: Returning 0 in a probe callback means the driver can handle this device. If by any chance xenstore is the first driver, every new device with the driver is unset will use xenstore. Note that with the changes, x86/include/xen/xen-os.h doesn't contain anymore arch-specific code. Although, a new series will add some helpers that differ between x86 and ARM64, so I've kept the headers for now.

xen/console: Introduce a new console driver for Xen guest The current Xen console driver is crashing very quickly when using it on an ARM guest. This is because the console lock is recursive and it may lead to recursion on the tty lock and/or corrupt the ring pointer. Furthermore, the console lock is not always taken where it should be and has to be released too early because of the way the console has been designed. Over the years, code has been modified to support various new features but the driver has not been reworked. This new driver has been rewritten with the idea of only having a small set of specific function to write either via the shared ring or the hypercall interface. Note that HVM support has been left aside for now because it requires additional features which are not yet supported. A follow-up patch will be sent with HVM guest support. List of items that may be good to have but not mandatory: - Avoid to flush for each character written when using the tty - Support multiple consoles Submitted by: Julien Grall <julien.grall@citrix.com> Reviewed by: royger Differential Revision: https://reviews.freebsd.org/D3698 Sponsored by: Citrix Systems R&D
