* kern: Add a mach host operation which returns elapsed time since bootupZhaoming Luo2024-12-291-0/+5
| | | | | | | | | | | | | | 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>

* Add vm_pages_physSamuel Thibault2024-01-301-0/+17
| | | | | | | | For rumpdisk to efficiently determine the physical address, both for checking whether it is below 4GiB, and for giving it to the disk driver, we need a gnumach primitive (and that is not conditioned by MACH_VM_DEBUG like mach_vm_region_info and mach_vm_object_pages_phys are).
* ddb: Add whatis commandSamuel Thibault2023-10-011-0/+4
| | | | This is convenient when tracking buffer overflows
* Remove host_get_boot_info and host_get_kernel_boot_info since they are not used.Flavio Cruz2023-04-071-14/+0
| | | | | | host_get_kernel_boot_info was added recently to fix the use of MACH_MSG_TYPE_STRING. Message-Id: <ZC5Sz8a4FCT6IjCY@jupiter.tail36e24.ts.net>
* Make exception subcode a longSergey Bugaev2023-04-031-2/+2
| | | | | | | | | On EXC_BAD_ACCESS, exception subcode is used to pass the faulting memory address, so it needs to be (at least) pointer-sized. Thus, make it into a long. This requires matching changes in glibc and the Hurd. Message-Id: <20230319151017.531737-4-bugaevc@gmail.com>
* Use c_string to define host_get_kernel_version and host_get_kernel_boot_info.Flavio Cruz2023-03-131-4/+4
| | | | | | | | | | | | | | 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 Cruz2023-01-281-2/+2
| | | | | | 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 Cruz2023-01-191-17/+25
| | | | | | 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.
* Make task_info.h structs more portableFlavio Cruz2022-12-061-9/+9
| | | | | | | | | | Changed vm_size_t to rpc_size_t so that both userland and kernel agree on the same size. Also changed the denominator for the maximum struct sizes to be integer_t to match the other declarations. Introduced long_natural_t and rpc_long_natural_t to represent large counters. Replaced rpc_unsigned_long with rpc_long_natural_t. Message-Id: <Y47UhaOzKnqhgYq4@reue>
* task: Add task_set_essentialSamuel Thibault2022-12-031-0/+11
| | | | | | | | Whenever a Hurd essential task crashes, startup just reboots the system since there's not much that can be done at that point. When we have a kernel debugger, however, we could at least get crashing information, so let's let Hurd's startup tell the kernel which tasks are essential, and trigger the debugger whenever they crash.

* Revert "Fix documentation for vm_map"Samuel Thibault2016-08-261-1/+1
| | | | | | | This reverts commit 57694037a02dda29bd678dc3b8531bd437682ba7. We rather prefer the kernel just use whatever slot it sees fit. Userland has already been fixed into not using the behavior anyway.

* doc: restore section `Inherited Ports'Justus Winter2014-10-101-62/+65
| | | | | | | | | | | | | | | | | | Previously, the section `Inherited Ports' was commented out. This was done, as the functionality was unused by the Hurd. The functions `mach_ports_register' and `mach_ports_lookup' were never removed, and are exposed to user space. This patch brings the documentation back and adds a remark at the top, that the section documents the original intentions for this interface. I chose bringing back the documentation over removing the functionality because I like to make use of it as a method for service discovery that is deliberately orthogonal to the way the service lookup is usually done in the Hurd. This can be used to implement robust low-level debugging facilities. * doc/mach.texi: Restore section `Inherited Ports'.
