* Check for null ports in task_set_essential, task_set_name and thread_set_name.Flavio Cruz2024-02-281-0/+3
| | | | | | Otherwise, it is easy to crash the kernel if userland passes arbitrary port names. Message-ID: <ZdriTgNhPsfu7c2M@jupiter.tail36e24.ts.net>
* Add thread_set_name RPC.Flavio Cruz2024-02-121-0/+20
| | | | | | | Like task_set_name, we use the same size as the task name and will inherit the task name, whenever it exists. This will be used to implement pthread_setname_np. Message-ID: <20240212062634.1082207-2-flaviocruz@gmail.com>
* Replace kernel header includes in include/mach/mach_types.h with forward ↵Flavio Cruz2024-02-121-0/+4
| | | | | | | | | | | | | | | declarations. I was trying to reuse TASK_NAME_SIZE in kern/thread.h but it was impossible because files included from kern/task.h end up requiring kern/thread.h (through percpu.h), creating a recursive dependency. With this change, mach_types.h only defines forward declarations and modules have to explicitly include the appropriate header file if they want to be able touch those structures. Most of the other includes are required because we no longer grab many different includes through mach_types.h. Message-ID: <20240212062634.1082207-1-flaviocruz@gmail.com>

* Update task_basic_info and thread_basic_info to include time_value64_t data.Flavio Cruz2023-04-271-4/+12

* Track task and thread time using time_value64_t.Flavio Cruz2023-03-131-8/+11
| | | | | | | | Changed kern/timer.c to use the higher precision time_value64_t. Of course, this won't suffer from the 2038 overflow but it does provide nanosecond precision (if gnumach ever uses a better timer) and moves us closer to only having time_value64_t.

So far it seems the only rpc to cause a conflict between the mig-generated header and the regular header, so compilation fails.

| | | | | | | | | | | A new thread will mosty probably start working, assume it will take its share of CPU, to avoid having to find it out slowly. Decaying will however fix that quickly if it actually does not work. This fixes stalling issues when a program keeps creating threads. * kern/thread.c (thread_create): Set new_thread's cpu_usage and sched_usage to a fair share of the current load.

* VM: improve pageout deadlock workaroundRichard Braun2016-09-161-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 5dd4f67522ad0d49a2cecdb9b109251f546d4dd1 makes VM map entry allocation done with VM privilege, so that a VM map isn't held locked while physical allocations are paused, which may block the default pager during page eviction, causing a system-wide deadlock. First, it turns out that map entries aren't the only buffers allocated, and second, their number can't be easily determined, which makes a preallocation strategy very hard to implement. This change generalizes the strategy of VM privilege increase when a VM map is locked. * device/ds_routines.c (io_done_thread): Use integer values instead of booleans when setting VM privilege. * kern/thread.c (thread_init, thread_wire): Likewise. * vm/vm_pageout.c (vm_pageout): Likewise. * kern/thread.h (struct thread): Turn member `vm_privilege' into an unsigned integer. * vm/vm_map.c (vm_map_lock): New function, where VM privilege is temporarily increased.

* Stack the slab allocator directly on top of the physical allocatorRichard Braun2016-02-021-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to increase the amount of memory available for kernel objects, without reducing the amount of memory available for user processes, a new allocation strategy is introduced in this change. Instead of allocating kernel objects out of kernel virtual memory, the slab allocator directly uses the direct mapping of physical memory as its backend. This largely increases the kernel heap, and removes the need for address translation updates. In order to allow this strategy, an assumption made by the interrupt code had to be removed. In addition, kernel stacks are now also allocated directly from the physical allocator. * i386/i386/db_trace.c: Include i386at/model_dep.h (db_i386_reg_value): Update stack check. * i386/i386/locore.S (trap_from_kernel, all_intrs, int_from_intstack): Update interrupt handling. * i386/i386at/model_dep.c: Include kern/macros.h.

* kern: add boot-time clock, use it for time stampsJustus Winter2015-07-251-1/+2
| | | | | | | | | | | | | | | | | | | | | | The kernel keeps track of task and thread creation times by saving a time stamp. Previously, the real-time clock was used for this. When the real-time clock is changed, however, the reference frame for the time stamps is lost. This surfaced in Hurd systems reporting spuriously long uptimes. Fix this by creating a boot-time clock and use it as reference frame for the time stamps. * kern/mach_clock.c (clock_boottime_offset): Create clock by keeping track of the offset from the real-time. (clock_boottime_update): New function. (record_time_stamp): Use the boot-time clock for time stamps. (read_time_stamp): New function to convert it back to real-time. (host_set_time): Call `clock_boottime_update'. * kern/mach_clock.h (record_time_stamp): Amend comment.

* kern: fix argument handlingJustus Winter2015-05-291-0/+3
| | | | | | | | | | Previously, the processor argument was not checked. If called with a non-processor argument (like a task), `processor' is set to NULL, triggering a page fault.

* kern: disable stack allocation counters by defaultJustus Winter2015-04-231-8/+7

Casual checking revealed that the hits-to-miss ratio is excellent. * kern/thread.c (stack_alloc_{hits,misses,max}): Move variables... * kern/counters.c: ... here, and add the usual counter prefix. * kern/counters.h: New declarations.
* kern: reduce the size of `struct thread'Justus Winter2015-02-201-6/+6
| | | | | | | | | | | | | | Reduce the size of `struct thread' by twelve bytes making it fit into exactly five cache lines (on 32-bit platforms). * kern/thread.h (struct thread): Group the state and all flags in a bitfield. (TH_EV_WAKE_ACTIVE, TH_EV_STATE): Provide macros that generate keys for synchronization primitives like `thread_wakeup'. * kern/thread.c (thread_halt, thread_dowait, thread_suspend): Use the new keys instead of addresses of fields for the synchronisation. * kern/ipc_sched.c (thread_handoff): Likewise. * kern/sched_prim.c (thread_invoke, thread_dispatch): Likewise.
* kern: avoid #if 0ing out thread_collect_scanJustus Winter2015-02-181-2/+0
| | | | | | | | | | | | | Currently, `thread_collect_scan' does nothing because `pcb_collect' is a nop. Its body is exempt from compilation by means of the preprocessor. This is unfortunate as it increases the risk of bitrot, and we still need to pay the price of rate-limiting thread_collect_scan. * kern/thread.c (thread_collect_scan): Drop #if 0 around the body. * vm/vm_pageout.c (vm_pageout_scan): Do not call `consider_thread_collect' and document why.
* kern: avoid the casts in enqueue_head() and enqueue_tail()Marin Ramesa2013-12-171-1/+1
| | | | | | * kern/eventcount.c (simpler_thread_setrun) (enqueue_head) (th): Avoid the cast. * kern/thread.c (thread_halt_self) (enqueue_tail) (thread): Likewise. * kern/thread_swap.c (thread_swapin) (enqueue_tail) (thread): Likewise.
