* kern: Add a mach host operation which returns elapsed time since bootupZhaoming Luo2024-12-291-0/+7
| | | | | | | | | | | | | | Add host_get_uptime64() mach interface operation. It can be used to get the time passed since the boot up. * doc/mach.texi: Add the documentation for the operation * include/mach/mach_host.defs: Add the interface * include/mach/time_value.h: Extend the mappable time variable * kern/mach_clock.c: Operation implementation * kern/mach_clock.h: Add a new variable for storing uptime Signed-off-by: Zhaoming Luo <zhmingluo@163.com> Message-ID: <20241224015751.1282-1-zhmingluo@163.com>
* Disable host_kernel_version() everywhere but on i386Sergey Bugaev2024-03-271-3/+3
| | | | | It's not only x86_64, none of new architectures are going to have it. Message-ID: <20240327161841.95685-3-bugaevc@gmail.com>

* Remove host_kernel_version RPC for x86_64Flavio Cruz2023-05-111-0/+4
| | | | | | | We can fast track the simplification of the RPC ABI for x86_64 if we don't have MACH_MSG_TYPE_STRING used in RPCs which forces msgt_size to use more than 8 bits. Message-Id: <ZFht+/9cVPHuV90D@jupiter.tail36e24.ts.net>
* Remove host_get_boot_info and host_get_kernel_boot_info since they are not used.Flavio Cruz2023-04-071-14/+2
| | | | | | host_get_kernel_boot_info was added recently to fix the use of MACH_MSG_TYPE_STRING. Message-Id: <ZC5Sz8a4FCT6IjCY@jupiter.tail36e24.ts.net>
* Use c_string to define host_get_kernel_version and host_get_kernel_boot_info.Flavio Cruz2023-03-131-0/+16
| | | | | | | | | | | | | | The existing definitions for kernel_version_t and kernel_boot_info_t use (MACH_MSG_TYPE_STRING, length*8) which result in message types that have a single element of 512 or 4096 bytes (set as msgt_size). This results in MiG generating mach_msg_type_long_t. Using c_string has the benefit of moving this size to be defined as msgt_number which doesn't overflow. This will allow us to simplify the 64 bit RPC ABI since all msgt_size can be defined with just 8 bits (as it should be expected). The resulting implementation is the same but we still need to define new RPCs since server and user expect different mach_msg_type_t. Message-Id: <ZA63pS8j9J6NwuXY@jupiter.tail36e24.ts.net>
* Add host_set_time64 and host_adjust_time64Flavio Cruz2023-01-281-0/+18
| | | | | | Same existing logic, just with 64 bits. Old RPCs are implemented by calling into the new RPCs. Message-Id: <Y9TJAmL2byOWup5x@jupiter.tail36e24.ts.net>
* Add host_get_time64 RPC to return the time as time_value64_tFlavio Cruz2023-01-191-0/+8
| | | | | | Also updated the mapped time to support the new 64-bit time while keeping compatible with the user land programs currently using it so they can be migrated in parallel.
* Allow non-privileged tasks to wire 64KiB task memorySamuel Thibault2015-07-091-1/+1
| | | | | | | | | | | | | | | | | * doc/mach.texi (vm_wire): Document that the host port does not have to be privileged. * include/mach/mach_hosts.defs (vm_wire): Use mach_port_t instead of host_priv_t. * vm/vm_map.h (vm_map): Add user_wired field. * vm/vm_map.c (vm_map_setup): Initialize user_wired field to 0. (vm_map_pageable_common, vm_map_entry_delete, vm_map_copy_overwrite, vm_map_copyout_page_list, vm_map_copyin_page_list): When switching user_wired_count field of entry between 0 and non-0, accumulate the corresponding size into the user_wired field of map. * vm/vm_user.c (vm_wire): Turn host parameter into port parameter, and inline a version of convert_port_to_host_priv which records whether the host port is privileged or not. When it is not privileged, check whether the additional amount to user_wired will overcome 64KiB.
* include: add X_IMPORTS to ipc definitionsJustus Winter2014-12-091-0/+4
