* Use c_string for dev_name_t in the device subsystem.Flavio Cruz2023-04-291-0/+8
| | | | | | | | | | | | Added device_open_new and device_open_new_request and reused the old MiG ID for xxx_device_set_status which has not been in used in the past decade. Note that device_open_new is gated on defining DEVICE_ENABLE_DEVICE_OPEN_NEW because otherwise some hurd servers wouldn't compile anymore unless patched. This macro allows us to control the rollout.

* Define vm_size_t and vm_offset_t as __mach_uintptr_t.Flavio Cruz2022-12-061-1/+1
| | | | | | | | | | This allows *printf to use %zd/%zu/%zx to print vm_size_t and vm_offset_t. Warnings using the incorrect specifiers were fixed. Note that MACH_PORT_NULL became just 0 because GCC thinks that we were comparing a pointer to a character (due to it being an unsigned int) so I removed the explicit cast.

* VM: improve pageout deadlock workaroundRichard Braun2016-09-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. (vm_map_unlock): New function, where VM privilege is decreased. (_vm_map_entry_create): Remove VM privilege workaround from this function. * vm/vm_map.h (vm_map_lock, vm_map_unlock): Turn into functions.
* Remove map entry pageability property.Richard Braun2016-09-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Since the replacement of the zone allocator, kernel objects have been wired in memory. Besides, as of 5e9f6f (Stack the slab allocator directly on top of the physical allocator), there is a single cache used to allocate map entries. Those changes make the pageability attribute of VM maps irrelevant. * device/ds_routines.c (mach_device_init): Update call to kmem_submap. * ipc/ipc_init.c (ipc_init): Likewise. * kern/task.c (task_create): Update call to vm_map_create. * vm/vm_kern.c (kmem_submap): Remove `pageable' argument.

* Stack the slab allocator directly on top of the physical allocatorRichard Braun2016-02-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
