GNU Mach 1.8

2016-12-18 Thomas Schwinge <[email protected]> GNU Mach 1.8 * version.m4 (AC_PACKAGE_VERSION): Set to 1.8. * NEWS: Finalize for 1.8. 2016-12-11 Richard Braun <[email protected]> VM: make vm_wire more POSIX-friendly * doc/mach.texi: Update return codes. * vm/vm_map.c (vm_map_pageable_common): Return KERN_NO_SPACE instead of KERN_FAILURE if some of the specified address range does not correspond to mapped pages. Skip unwired entries instead of failing when unwiring. 2016-12-09 Justus Winter <[email protected]> Update the NEWS file 2016-12-09 Richard Braun <[email protected]> rbtree: minor change * kern/rbtree.h (rbtree_for_each_remove): Remove trailing slash. 2032-05-12 Richard Braun <[email protected]> VM: fix pageout throttling to external pagers Since the VM system has been tracking whether pages belong to internal or external objects, pageout throttling to external pagers has simply not been working. The reason is that, on pageout, requests for external pages are correctly tracked, but on page release (which is used to acknowledge the request), external pages are not marked external any more. This is because the external bit tracks whether a page belongs to an external object, and all pages, including external ones, are moved to an internal object during pageout. To solve this issue, a new "external_laundry" bit is added. It has the same purpose as the laundry bit, but for external pagers. * vm/vm_page.c (vm_page_seg_min_page_available): Function unused, remove. (vm_page_seg_evict): Use vm_page_external_laundry_count instead of vm_page_external_pagedout. Add an assertion about double paging. (vm_page_check_usable): Use vm_page_external_laundry_count instead of vm_page_external_pagedout. (vm_page_evict): Likewise. * vm/vm_page.h (struct vm_page): New `external_laundry' member. (vm_page_external_pagedout): Rename to ... (vm_page_external_laundry_count): ... this. * vm/vm_pageout.c: Include kern/printf.h. (DEBUG): New macro. (VM_PAGEOUT_TIMEOUT): Likewise. (vm_pageout_setup): Use vm_page_external_laundry_count instead of vm_page_external_pagedout. Set `external_laundry' where appropriate. (vm_pageout): Use VM_PAGEOUT_TIMEOUT with thread_set_timeout. Add debugging code, commented out by default. * vm/vm_resident.c (vm_page_external_pagedout): Rename to ... (vm_page_external_laundry_count): ... this. (vm_page_init_template): Set `external_laundry' member to FALSE. (vm_page_release): Rename external parameter to external_laundry. Slightly change pageout resuming. (vm_page_free): Rename external variable to external_laundry. 2016-11-30 Richard Braun <[email protected]> VM: fix pageout on low memory Instead of determining if memory is low, directly use the vm_page_alloc_paused variable, which is true when memory has reached a minimum threshold until it gets back above the high thresholds. This makes sure double paging is used when external pagers are unable to allocate memory. * vm/vm_page.c (vm_page_seg_evict): Rename low_memory to alloc_paused. (vm_page_evict_once): Remove low_memory and its computation. Blindly pass the new alloc_paused argument instead. (vm_page_evict): Pass the value of vm_page_alloc_paused to vm_page_evict_once. 2016-11-30 Richard Braun <[email protected]> VM: fix eviction logic error * vm/vm_page.c (vm_page_evict): Test both vm_page_external_pagedout and vm_page_laundry_count in order to determine there was "no pageout". 2016-11-30 Richard Braun <[email protected]> VM: fix pageout stop condition When checking whether to continue paging out or not, the pageout daemon only considers the high free page threshold of a segment. But if e.g. the default pager had to allocate reserved pages during a previous pageout cycle, it could have exhausted a segment (this is currently only seen with the DMA segment). In that case, the high threshold cannot be reached because the segment has currently no pageable page. This change makes the pageout daemon identify this condition and consider the segment as usable in order to make progress. The segment will simply be ignored on the allocation path for unprivileged threads, and if this happens with too many segments, the system will fail at allocation time. * vm/vm_page.c (vm_page_seg_usable): Report usable if the segment has no pageable page. 2016-11-10 Brent Baccala <[email protected]> gsync: Avoid NULL pointer dereference * kern/gsync.c (gsync_wait, gsync_wake, gsync_requeue): Return immediately if task argument is TASK_NULL 2016-11-06 Justus Winter <[email protected]> Revert "i386: use ACPI to power off the machine" This reverts commit c031b41b783cc99c0bd5aac7d14c1d6e34520397. Adding the ACPI parser from GRUB was a mistake as its license conflicts with the one used by the legacy Linux drivers. Furthermore, adding support for ACPI to the kernel violates the minimality principle. 2016-11-04 Justus Winter <[email protected]> vm: Print names of maps in the debugger. * vm/vm_map.c (vm_map_print): Print name of the map. 2016-11-01 Justus Winter <[email protected]> include: Fix new task notifications.

(mach_notify_new_task): Use the new type. 2016-11-01 Justus Winter <[email protected]> i386: Use discontiguous page directories when using PAE. Previously, we used contiguous page directories four pages in length when using PAE. To prevent physical memory fragmentation, we need to use virtual memory for objects spanning multiple pages. Virtual kernel memory, however, is a scarce commodity. * i386/intel/pmap.h (lin2pdenum): Never include the page directory pointer table index. (lin2pdenum_cont): New macro which does include said index. (struct pmap): Remove the directory base pointer when using PAE. * i386/intel/pmap.c (pmap_pde): Fix lookup.

And while we're at it, let's fix some of the defects that have been plaguing pageout forever, such as throttling, and pageout of internal versus external pages (this commit notably introduces a hardcoded policy in which as many external pages are selected before considering internal pages). * kern/slab.c (kmem_pagefree_physmem): Update call to vm_page_release. * vm/vm_page.c: Include <kern/counters.h> and <vm/vm_pageout.h>.

This commit mostly deals with the impact of this change on the page allocation interface. * i386/intel/pmap.c (pmap_page_table_page_alloc): Update call to vm_page_grab. * kern/slab.c (kmem_pagealloc_physmem): Use vm_page_grab instead of vm_page_grab_contig.

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.

Releasing this data is done with a vm_deallocate call.

This change makes the slab allocator revert to kernel virtual memory when allocating larger-than-page slabs. This solution is motivated in part to avoid the complexity of other solutions such as page mobility, and also because a microkernel cannot be extended to new arbitrary uncontrolled usage patterns such as a monolithic kernel with loadable modules. As such, large objects are rare, and their use infrequent, which is compatible with the use of kernel virtual memory. * kern/slab.c: Update module description.

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.

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'. 2014-10-01 Justus Winter <[email protected]> Add protected payloads to NEWS ipc: provide the protected payload in ipc_kmsg_copyout_header * ipc/ipc_kmsg.c (ipc_kmsg_copyout_header): If a protected payload is set for the destination port, provide it in msgh_protected_payload. * ipc/mach_msg.c (mach_msg_trap): Likewise in the fast paths. * doc/mach.texi (Message Receive): Document message semantics with protected payloads. include: define MACH_MSG_TYPE_PROTECTED_PAYLOAD * include/mach/message.h: Define MACH_MSG_TYPE_PROTECTED_PAYLOAD.

It never was a problem in practice, since the messages are not complex and thus the kernel does not try to parse the message. struct net_rcv_msg contains an additional field of type boolean_t. This field has no associated type descriptor, so it must not be included in the message. * device/net_io.c (net_deliver): Account for the extra field in the msgh_size calculation. 2014-05-27 Samuel Thibault <[email protected]> Add missing memory clobber * i386/i386/xen.h (mb, rmb, wmb): Add memory clobber. 2014-05-25 Justus Winter <[email protected]> Rewrite old-style #endif FOO directives * i386/include/mach/i386/cthreads.h: Rewrite old-style #endif FOO directives. * include/device/tape_status.h: Likewise. * include/mach/alert.h: Likewise. * include/mach/boot.h: Likewise. * include/mach/default_pager_types.defs: Likewise. * include/mach/default_pager_types.h: Likewise. * include/mach/multiboot.h: Likewise. * include/mach/notify.defs: Likewise. * include/mach_debug/pc_info.h: Likewise. * kern/act.h: Likewise. * kern/refcount.h: Likewise. * kern/shuttle.h: Likewise. 2014-05-25 Justus Winter <[email protected]> include: fix the embedded type definitions in memory_object.defs In order to use MIG translation functions to lookup memory objects, preprocessor macros have been introduced into the definition of memory_object_t in 50cc5152. The procedure definitions contain inlined type definitions in order to change the type of the argument in question (i.e. to make it polymorphic). The inline definitions however lack the destructor function, leading to reference leaks when a reference is acquired in the intran function. * include/mach/memory_object.defs: Add the destructor functions to the inlined type definitions. 2014-05-03 Justus Winter <[email protected]> ddb: add "halt" command * ddb/db_command.c (db_command_table): Add "halt" command. * i386/i386/db_interface.h (db_halt_cpu): New declaration. * i386/i386at/model_dep.c (db_halt_cpu): New function. 2014-04-30 Justus Winter <[email protected]> vm: make struct vm_map fit into a cache line Currently, the size of struct vm_map is 68 bytes. By using a bit field for the boolean flags, it can be made fit into a cache line. * vm/vm_map.h (struct vm_map): Use a bit field for the boolean flags wait_for_space and wiring_required. 2014-04-30 Justus Winter <[email protected]> i386: fix MACHINE_SERVER_HEADER Commit b6dab094 introduced a way to include the MIG-generated server files for the machine specific interface in ipc_kobject.c. This broke out-of-tree builds. Here, 'machine' is a symlink to '../i386/i386', it points into the source tree. The MIG-generated files however are put in the build tree in i386/i386. * i386/i386/machine_routines.h (MACHINE_SERVER_HEADER): Fix path. 2014-04-30 Justus Winter <[email protected]> kern: include the MIG-generated server headers for MACHINE_SERVER GNU MIG recently gained support for emitting x_server_routine declarations in the generated server header file. Using this declaration, the x_server_routine functions can be inlined into the ipc_kobject_server function. * kern/ipc_kobject.c: Include the MIG-generated server headers for the machine-dependent interfaces. (ipc_kobject_server): Drop the simple declaration of MACHINE_SERVER_ROUTINE. * i386/i386/machine_routines.h (MACHINE_SERVER_HEADER): New definition. 2014-04-30 Justus Winter <[email protected]> include: do not guard the host_slab_info RPC with MACH_VM_DEBUG Previously, the definition of the host_slab_info RPC was guarded with MACH_VM_DEBUG, even though it is not at all concerned with the VM subsystem. Furthermore, there was no "skip" directive for host_slab_info. The function host_slab_info is guarded with MACH_DEBUG. The server for the RPCs in mach_debug.defs is only used if MACH_DEBUG is defined. There is no need to guard host_slab_info. * include/mach_debug/mach_debug.defs (host_slab_info): Unconditionally include the RPC. 2014-04-30 Justus Winter <[email protected]> Install the mach_debug header files The task_set_name RPC introduced in 877a319c changed include/mach/gnumach.defs to include mach_debug/mach_debug_types.defs. Previously though, the debug headers were not installed. * Makefrag.am: Install the mach_debug header files. 2014-04-30 Justus Winter <[email protected]> doc: fix the number of priorities The number of priorities has been changed from 32 to 50 in 6a234201081156e6d5742e7eeabb68418b518fad. * doc/mach.texi: Update accordingly. 2014-04-25 Samuel Thibault <[email protected]> Make sure mig is available * configure.ac (MIG): Error out if MiG was not found. 2014-04-13 Justus Winter <[email protected]> kern: set the name of tasks created during the bootstrap * kern/bootstrap.c (boot_script_task_create): Set the name of newly created tasks. 2014-04-10 Justus Winter <[email protected]> include: fix the definition of device_open Previously, every userspace server implementing the device protocol filtered the device definitions to replace the device_t type with mach_port_send_t to make the device argument of device_open polymorphic. Rather than doing that, which makes it impossible to use translation functions, fix the definition of device_open. * include/device/device.defs (device_open): Redefine the device argument to make it polymorphic unless a outran function is specified. 2014-04-08 Justus Winter <[email protected]> include: make the device_t types translation functions mutable Make the intran, outtran and destructor functions mutable using preprocessor macros.

As the pageout daemon evicts pages, it collects cached objects that have become empty. The effective result is a graceful adjustment of the number of objects related to memory management (virtual memory objects, their associated ports, and potentially objects maintained in the external memory managers). Physical memory can now be almost entirely filled up with cached pages. In addition, these cached pages are not automatically deactivated as objects can quickly be referenced again. There are problems with this patch however. The first is that, on machines with a large amount of physical memory (above 1 GiB but it also depends on usage patterns), scalability issues are exposed. For example, file systems which don't throttle their writeback requests can create thread storms, strongly reducing system responsiveness. Other issues such as linear scans of memory objects also add visible CPU overhead. The second is that, as most memory is used, it increases the chances of swapping deadlocks. Applications that map large objects and quickly cause lots of page faults can still easily bring the system to its knees. 2013-09-28 Samuel Thibault <[email protected]> Add files missing in distrib tarball * Makefrag.am (libkernel_a_SOURCES): Add ddb/db_write_cmd.h, ipc/ipc_print.h, vm/vm_print.h * linux/Makefrag.am (EXTRA_DIST): Add linux/src/drivers/scsi/FlashPoint.c, linux/src/drivers/scsi/eata_pio_proc.c, linux/src/drivers/scsi/scsiiom.c. 2013-09-27 Thomas Schwinge <[email protected]> Merge remote-tracking branch 'savannah/master' into master GNU Mach 1.4. * version.m4 (AC_PACKAGE_VERSION): Set to 1.4. * NEWS: Finalize changes for 1.4. * README: Update. * configure.ac (AM_INIT_AUTOMAKE): Add dist-bzip2.

The dev/glue/block.c code deals with BSD disklabels and expects the Linux genhd.c code to handle only the DOS partitions; having genhd.c do BSD disklabels too just confuses things. Force subdirectory targets so they get recompiled properly. * i386/Makefile.in (linux/linux.o): Depend on FORCE instead of linux. (FORCE): New target. * i386/Makefrag (i386/sysdep.o, FORCE): Likewise. 1999-07-11 Thomas Bushnell, BSG <[email protected]> * i386/i386at/model_dep.c (init_alloc_aligned): Make the checks correctly for addresses falling into skip regions.

Help keep track of the number of externally managed pages that we care about. * i386/intel/pmap.c (pmap_page_table_page_alloc): Add new arg for vm_page_grab. * linux/dev/glue/block.c (alloc_buffer, device_read): Likewise. * vm/vm_map.c (vm_map_copy_steal_pages): Likewise. * vm/vm_fault.c (vm_fault_page): Add new args for vm_page_grab and vm_page_convert. * vm/vm_pageout.c (VM_PAGEOUT_BURST_WAIT): Reduce to 10ms/page.
