* vm_map_lookup: Add parameter for keeping map lockedDamien Zammit2024-02-221-1/+1
| | | | | | | | | | | This adds a parameter called keep_map_locked to vm_map_lookup() that allows the function to return with the map locked. This is to prepare for fixing a bug with gsync where the map is locked twice by mistake. Co-Authored-By: Sergey Bugaev <bugaevc@gmail.com> Message-ID: <20240222082410.422869-3-damien@zamaudio.com>
* vm: Add vm_map_coalesce_entrySergey Bugaev2023-11-271-0/+2
| | | | | | This function attempts to coalesce a VM map entry with its preceeding entry. It wraps vm_object_coalesce. Message-ID: <20230705141639.85792-3-bugaevc@gmail.com>

* VM: rework map entry wiringRichard Braun2016-12-241-12/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First, user wiring is removed, simply because it has never been used. Second, make the VM system track wiring requests to better handle protection. This change makes it possible to wire entries with VM_PROT_NONE protection without actually reserving any page for them until protection changes, and even make those pages pageable if protection is downgraded to VM_PROT_NONE. * ddb/db_ext_symtab.c: Update call to vm_map_pageable. * i386/i386/user_ldt.c: Likewise. * ipc/mach_port.c: Likewise. * vm/vm_debug.c (mach_vm_region_info): Update values returned as appropriate. * vm/vm_map.c (vm_map_entry_copy): Update operation as appropriate.

* VM: improve pageout deadlock workaroundRichard Braun2016-09-161-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Braun2016-09-071-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. Update call to vm_map_setup. (kmem_init): Update call to vm_map_setup. * vm/vm_kern.h (kmem_submap): Update declaration. * vm/vm_map.c (vm_map_setup): Remove `pageable' argument. Don't set `entries_pageable' member. (vm_map_create): Likewise. (vm_map_copyout): Don't bother creating copies of page entries with the right pageability. (vm_map_copyin): Don't set `entries_pageable' member. (vm_map_fork): Update call to vm_map_create. * vm/vm_map.h (struct vm_map_header): Remove `entries_pageable' member. (vm_map_setup, vm_map_create): Remove `pageable' argument.
* Augment VM maps with task namesRichard Braun2016-08-061-0/+8
| | | | | | | | | | | | This change improves the clarity of "no more room for ..." VM map allocation errors. * kern/task.c (task_init): Call vm_map_set_name for the kernel map. (task_create): Call vm_map_set_name where appropriate. * vm/vm_map.c (vm_map_setup): Set map name to NULL. (vm_map_find_entry_anywhere): Update error message to include map name. * vm/vm_map.h (struct vm_map): New `name' member. (vm_map_set_name): New inline function.
* vm_map: back allocations with a red-black treeRichard Braun2016-05-201-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | This change augments VM maps with a gap tree, sorted by gap size, to use for non-fixed allocations. * vm/vm_map.c: Include kern/list.h. (vm_map_entry_gap_cmp_lookup, vm_map_entry_gap_cmp_insert, vm_map_gap_valid, vm_map_gap_compute, vm_map_gap_insert_single, vm_map_gap_remove_single, vm_map_gap_update, vm_map_gap_insert, vm_map_gap_remove, vm_map_find_entry_anywhere): New functions. (vm_map_setup): Initialize gap tree. (_vm_map_entry_link): Call vm_map_gap_insert. (_vm_map_entry_unlink): Call vm_map_gap_remove. (vm_map_find_entry, vm_map_enter, vm_map_copyout, vm_map_copyout_page_list, vm_map_copyin): Replace look up loop with a call to vm_map_find_entry_anywhere. Call vm_map_gap_update and initialize gap tree where relevant. (vm_map_copy_insert): Turn macro into an inline function and rewrite. (vm_map_simplify): Reorder call to vm_map_entry_unlink so that previous entry is suitable for use with gap management functions. * vm/vm_map.h: Include kern/list.h. (struct vm_map_entry): New members `gap_node`, `gap_list`, `gap_size` and `in_gap_tree`. (struct vm_map_header): New member `gap_tree`.
* Stack the slab allocator directly on top of the physical allocatorRichard Braun2016-02-021-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

When it is not privileged, check whether the additional amount to user_wired will overcome 64KiB.
