Axel Dörfler 7e9f5d25d3 * WindowLayer::InWorkspace() was actually nowhere used the way it was
implemented; it now only returns wether or not the window is part of the
  list specified by the index. This fixes bug #195 and #1553.
* HasInSubset() would report "true" for app-floating windows vs. modal app
  windows which was wrong.
* Removed SameSubset() as it isn't needed at all.
* SubsetWorkspaces() now take the front window into account for floating
  windows.
* Minor cleanup.

Axel Dörfler 4191a211aa * Started accelerant extension to be able to get the preferred mode from
the accelerant, as well as its EDID info. B_GET_PREFERRED_DISPLAY_MODE and
  B_GET_EDID_INFO are both optional. The preferred mode will be taken from the
  EDID info if only the latter hook is implemented, or the former returned an
  error.
* Currently, the app_server should correctly set the preferred mode on start,
  but no accelerant supports that yet, so it's not really tested.

Axel Dörfler 7bdf92f3f7 Started a create_display_modes() function that should be used by accelerants
to create their mode list. Once it's done, it should cover all possible cases,
and allow the base mode list to reside in the app_server (under Haiku, at least),
so that all drivers will benefit from an updated list.
Right now, it might already work to a degree, but it's not yet tested.

Axel Dörfler 4ff0c50078 * The loop that should select a thread of the next priority class actually did
not work; it would always choose the last thread of the current priority.
  IOW a thread was never skipped, and lower priority threads were never called
  when a higher priority thread was running - from the POV of the scheduler,
  we only has real time threads...
* Improved "run_queue" KDL output.
* Minor cleanup.

Axel Dörfler dd980a197c Started working on a test application for the scheduler; it uses the scheduler
of the kernel directly, and emulates the kernel's API where necessary.
Not complete at all yet, but I already found one serious bug in our current
scheduler with it :-)

Axel Dörfler f8941839c3 * Reworked stealing pages: the page thief thread is gone now,
vm_page_reserve_pages() and vm_page_allocate_page() will now steal pages from
  the inactive queue as needed.
* We currently never steal active pages anymore, but this might need to be
  revised later (therefore, the page scanner never waits anymore, but uses
  mutex_trylock() to lock a cache).
* The page scanner and writer now both run at normal priority - let's see how
  that will work out.
* Introduced an inactive queue.
* Instead of shuffling pages around in the queue (and therefore destroying LRU)
  the page stealing mechanism now uses a marker page to be able to release the
  page lock without losing its position in the queue.
* The page writer now always grabs the whole release count of the semaphore, so
  that there won't be a huge backlog to catch up with. 
* vm_page_num_free_pages() now also includes the inactive queue as well as the
  reserved pages (they are no longer regarded as free pages).
* Added a insert_page_after() function that inserts a page after another one,
  needed by the marker code.
* clear_page() now gets a vm_page instead of a physical address which simplified
  some code.
* Removed superfluous initialization of the queues (if those aren't zeroed on
  start, we would have serious problems, anyway).
* Removed old and unimplemented dump_free_page_table() ("free_pages") KDL
  command.

Axel Dörfler 013f781f47 vm_test_map_{modification|activation}(), vm_clear_map_flags(), and
vm_remove_all_page_mappings() all computed the wrong virtual address for the
page in question, and would therefore return incorrect data!
Introduced a virtual_page_address() function that is now used by all of them.
So that's why we were still "losing" modified flags - it took me some hours
to find those (sometimes processes died after stealing pages)...

Axel Dörfler 477c9d1dc0 * vm_set_area_protection() would remap the whole area instead of just the page
it intended to. That resulted in more writable pages where you wouldn't want
  them (ie. allowing the area to change pages in lower caches).
* We were losing modified pages: vm_unmap_pages() sometimes has to preserve
  the modified flag (eg. when called from page fault).
* Both of these were responsible that stealing active pages would crash
  applications - even if less likely, this could also have happened when
  stealing inactive pages. Therefore, I've activated stealing active pages
  again.
* The page writer now pushes the pages of busy vnodes to the end of the queue,
  so that it won't pick them up again too soon (the vnode destruction would
  be in the process of writing those pages back, anyway).
* The page thief now triggers the page writer to run once it has to steal
  active pages. This might be a bit too aggressive, though.

Axel Dörfler 0d871d3c5f * satisfy_cache_io() was using the wrong value to compute the number of

Axel Dörfler ace15ce212 Changed defaults in readline to be more useful. This fixes bug #1540.
Alternatively, we could add an inputrc file - this would have the advantage
that other apps using readline built-in would have those, too.
OTOH this really should be in the defaults, too, IMO (ie. we could do both).
Opinions welcome :-)

Axel Dörfler 873f2ffc1a * Fixed the page_thief(): it never noticed it could not get a page.
* The page_thief() will no longer steal any pages in B_LOW_MEMORY_NOTE state,
  only in the more serious cases.
* I've disabled stealing active pages for now again; there seem to be some
  problems with it (either with how we do it, or with other stuff).
* vm_page_schedule_write_page() now always releases the page writer semaphore,
  resulting in many more written pages - this isn't optimal as long as there is
  no I/O scheduler, but before it was much too rare when there are many dirty
  pages.
* Customized the thread priorities a bit to make the page scanner/thief/writer
  experience a bit nicer with our current scheduler.
* vm_page_reserve_pages() would return too early, it did not test if really
  enough pages are free.
* Under certain circumstances, the wakeup from vm_page_reserve_pages() did not
  work - we now always notify in vm_page_unreserve_pages() to work around that
  problem.
* Checked if the page reservations are done when needed and are always balanced
  for the whole kernel.
* vm_page_allocate_page() now panics if it can't deliver a reserved page.
* vm_page_allocate_page_run() can no longer steal reserved pages.
* With all of those changes, I could finally copy a file in emulation, ie. the
  Luposian bug should finally be fixed, even though the system might still not
  be perfectly stable under low memory. Will do some more testing.
* write_page() no longer prints something on failure.
* Dumping a whole page queue will now also write the cache type of each page.

Axel Dörfler 0710d59c1c * Added a "canWait" argument to vfs_get_vnode() - you can use this to ignore
busy vnodes.
* dir_create_entry_ref() used get_vnode() incorrectly (and could therefore
  potentially prevent a file system from doing proper locking when called
  from the kernel).
* The vnode_store now uses this for its acquire_unreferenced_ref()
  implementation (and therefore for the page writer).
* read_into_cache() and write_to_cache() were still marked inline.
* The system will now wait 10 secs for a busy vnode before returning an error.
* It will also no longer panic in that case.

Axel Dörfler 20b232e900 Actually forgot this nail: the file cache will now reserve the pages it will
allocate with the vm_cache locked - this is necessary to be able to steal pages
from itself (large files...).
The system doesn't actually lock up anymore, but it still renders itself unusable;
obviously the page thief does not work correctly, yet. The rest of the experience
is created by our current scheduler (the page thief runs and runs, but it doesn't
free any pages anymore).

2007-10-07 13:32:13 +00:00
Axel Dörfler 0633dcc2c6 * Fixed a serious oversight that could result in trying to insert a page
twice into the same cache: cache_io() called read_into_cache() (or
  write_to_cache()), and that broke down the request into smaller parts.
  It then called read_chunk_into_cache() (or write_chunk_to_cache() resp.)
  to actually allocate pages and fulfill the request.
  However, it needed to unlock the cache for each chunk, and in the mean
  time someone else could insert pages into the remaining chunks.
* Now, cache_io() already takes care of chunking the data which makes this
  approach safe, and also simplified the code a bit - read_into_cache()/
  write_to_cache() are gone now. I've renamed read_chunk_into_cache() to
  read_into_cache() (same for the write function).
* Also got rid of that goto in that function while I was on it.
* Disabled cache_prefetch_vnode() for now (it's similar to cache_io(), but
  since it's currently not used [since no cache module is installed yet],
  I didn't want to go through updating it now, too).

Axel Dörfler 0e18334057 * Mapping a page might actually need memory - since we usually have locks that
interfere with the page thief, we always need to have reserved a page for
  this upfront. I introduced a function to the vm_translation_map layer that
  estimates how much pages a mapping might need at maximum. All functions that
  map a page now call this and reserve the needed pages upfront.
  It might not be a nice solution, but it works.
* The page thief could run into a panic when trying to call vm_cache_release_ref()
  on a non-existing (NULL) cache.
* Also, it will now ignore wired active pages.
* There is still a race condition between the page writer and the vnode
  destruction - writing a page back needs a valid vnode, but that might just
  have been deleted.

Axel Dörfler 9f0d226c72 The no-swap store shouldn't fool the page writer into believing that its pages

pages that cannot be recreated easily :-)

Axel Dörfler 083de48a4b * Rewrote the trigger selection mechanism: it now searches for uppercase
characters first, and then falls back to take everything. fTrigger is now
  uint32 and works with all unicode characters; unlike in BeOS, the
  MenuTriggerTest application now works correctly in Haiku.
* fTriggerIndex is now a character position, not a byte position of the label;
  this allows BMenuItem::DrawContent() to draw the trigger at the correct
  position, even if there are multi-byte UTF-8 characters.
* The above fixed bug #1506; triggers are still not working, though.
* Rewrote Menu.h header.
* Renamed all private methods (that are not called by BWindow) to have the
  underscore prefix.
* Removed unused methods.
* Some minor cleanup.

Axel Dörfler b15c9adec7 * Decoupled the page_thief() from the low memory handler chain. This is
necessary because low memory handlers might need to wait for other services
  while we need to make sure the page thief can always steal pages.
* Made the page thief more aggressive when memory is critical: added a third
  run where it will also steal a small amount of active pages to keep things
  going.
* The page thief did not maintain the cache's reference correctly in all
  situations.

Axel Dörfler b062823d81 * register_low_memory_handler() was called too early by several kernel
components - now, we divide the initialization of that service into two parts
  which allows this (before, most handlers were gone after boot).
* Added debugger command that dumps the low memory handlers.
* The slab allocator now registers its low memory handler with a higher
  priority, so that it'll run before the potentially heavier ones.

Axel Dörfler ab88b095f2 * bfs_{read|write}_pages() now only try to lock - this fixes a possible
deadlock whenever someone without a lock (like the page_writer()) is calling
  this function.
* Added a new ReadWriteLock::TryLock() method.
* Renamed bfs_read_vnode() and bfs_release_vnode() to bfs_get_vnode() and
  bfs_put_vnode() just like those functions are called in fs_interface.h.
* Fixed a warning in BPlusTree::_SplitNode().

Axel Dörfler a6778735f9 bonefish+axeld:
* We now have a page writer that takes some pages from the modified queue
  and writes it back every few seconds. It can be triggered by the page
  scanner to do that more often, though. That mechanism can be greatly
  improved once we have our I/O scheduler working.
* Removed vm_page_write_modified_page() again - it was all "eaten up" by
  the page writer.
* Reworked vm_page_write_modified_pages() a bit: it now uses
  vm_test_map_modification() and vm_clear_map_flags() instead of the
  iterating over all areas which wouldn't even work correctly.
  The code is much simpler now, too.
* You usually put something to the tail of a queue, and remove the contents
  from the head, not vice versa - changed queue implementation to reflect this.
* Additionally, there is now a enqueue_page_to_head() if you actually want the
  opposite.
* vm_page_requeue() allows you to move a page in a queue to the head or tail.
* Replaced vm_clear_map_activation() with vm_clear_map_flags() which allows
  you to clear other flags than PAGE_ACCESSED.
* The page scanner dumps now some arguments with each run.
* Removed the old disabled pageout_daemon() from NewOS.

Axel Dörfler 5c4ed86b56 * Moved some definitions from vm_types.h that functions in vm.h need as

Axel Dörfler e6dc7903e4 * vm.h no longer includes vm_types.h - only those that actually need access
to the private VM types are including vm_types.h now.
* Removed vm_page, vm_area, vm_cache, and vm_address_space typedefs; it's
  cleaner this way, and the actual types are only used in C++ files now,
  anyway.
* And that caused changes in many files...
* Made commpage.h self-containing.

Axel Dörfler 393fceb5a0 * Cleaned up vm_types.h a bit, and made vm_page, vm_cache, and vm_area

  all warnings caused by that.

Axel Dörfler 8692ec023c * Renamed vm_page_write_modified() to vm_page_write_modifed_pages() and
introduced a new vm_page_write_modified_page().
* Resolved a TODO: vm_page_write_modified_pages() did not mark a to be
  written page busy but unlocked its cache which could let someone else
  steal that page in the mean time.
* Moved the logic when to move a page to the active or inactive queue to
  a new function move_page_to_active_or_inactive_queue().
* Moved page_state_to_string() to vm_page(); it's now also used by the
  "page" and "page_queue" KDL commands.
* Made the output of the "page_queue list" command more useful.

2007-09-26 20:19:51 +00:00
Axel Dörfler 44e2fd093c Actually, it's not a good idea to increase the usage_count, since every access
is tracked while the page scanner runs much slower. Now, we just set it to a
fixed positive, so that they can easily age in case they are actually unused.

2007-09-26 18:00:45 +00:00
Axel Dörfler 8e0f884c71 * Since the page scanner and thief can work more effectively when no vm_caches
are locked, there is now a vm_page_reserve_pages() call to ensure upfront that
  there is a page for me when I need it, and may have locked some caches.
* The vm_soft_fault() routine now makes use of that feature.
* vm_page_allocate_page() now resets the vm_page::usage_count, so that the file
  cache does not need to do this in read_chunk_into_cache() and
  write_chunk_to_cache().
* In cache_io() however, it need to update the usage_count - and it does that
  now. Since non-mapped caches don't have mappings, the page scanner will punish
  the cache pages stronger than other pages which is accidently just what we
  want.

Axel Dörfler e97e022aa7 * block_cache_set_dirty() was used incorrectly; I wonder why I write any

* Minor style cleanup.

Axel Dörfler 6d4aea4796 bonefish+axeld:
* Removed the vm_cache/vm_store ref_count duality that besides being a bit ugly
  also created the page dameon cache retrieval problem: now, only areas (and
  cache consumers) retrieve a reference to the store (and therefore, the vnode).
  The page daemon doesn't need to care about this at all anymore, and the pseudo
  references of the vm_cache could be removed again.
* Rearranged deletion of vnodes such that its ID can be reused directly after
  fs_remove_vnode() has been called.
* vm_page_allocate_page() no longer panics when it runs out of pages, but just
  waits for new pages to become available using the new sFreeCondition condition
  variable - to make sure this happens in an acceptable time frame, it'll
  trigger a run of the low memory handlers.
* Implemented a page_thief() that steals inactive pages from caches and puts
  them into the free queue. It runs as a low memory handler.
* The file cache now sets the usage count on the pages it inserts into the
  cache (needs some rework though, cache_io() doesn't do it yet).
* Instead of panicking, the kernel will currently dead lock in low memory
  situations, since BFS does a bit too much in bfs_release_vnode().
* Some minor cleanup.

Axel Dörfler f9057a35a0 bonefish+axeld:

  the interval between runs with increasing memory pressure.

Axel Dörfler 64fd7c1a00 This fixes the problem of launching more than one document with one application
at once with Tracker (eg. launching several text documents) - only the first one
would have been opened, and an error B_BAD_VALUE would have been reported for the
others:
* HandleAddApplication() did not return the correct token in case of a
  pending registration; therefore, BRoster::_LaunchApp() would try to
  check the registration with invalid arguments.
* HandleIsAppRegistered() put the pending registration requests into
  the fIARRequestsByToken map using the wrong key, so that they could
  not be found again.
* Minor cleanup (fixed indentation of not so temporary debug code).

Axel Dörfler cbd4081064 * Fixed PLL timing computation for the i9xx chips - I mixed post2 min/max values, and did
not take the VCO limits into account; both could (and would during testing) create invalid
  frequencies.
* Also reverted the order in which the PLL divisors are traversed to match the order of what
  is used in the X driver to create comparable output (our error computation is based on float,
  though, and should therefore create more accurate values).
* The i965 introduced a special register for the surface; the former display base register
  is now only used for the view offset. Instead of setting the base manually here and there,
  there is now a set_frame_buffer_base() function.
* The DPMS code will now also turn off/on the PLL clock generator.
* The code needs some more cleanup, and while the driver now produces the correct timing on
  my i965 system, I'm now greeted by a black screen after startup.

Axel Dörfler 93a1ccabb9 * Separated I2C from DDC a bit more.
* i2c_bus now contains a i2c_timing structure, so that you don't need
  both to talk to the I2C bus.
* Therefore, there is now a void ddc2_init_timing() function to get the
  the timing DDC needs.
* Cleanup in radeon's monitor_detection.c, and updated it to work with
  the DDC/I2C changes.

Axel Dörfler 61dad86a02 * No longer switch between divisor register set 0 and 1; it doesn't really
make any sense.
* "pll" might have been set incorrectly on i8xx chips.

Axel Dörfler ef27f7d0e0 Ported over atftpd from Linux - should work on BSD as well, now.
Not yet tested, and it will probably not work correctly until we support
IP_RECVDSTADDR correctly (we don't support that CMSG stuff yet).

Axel Dörfler 87689e25ea * sMappingLock is now a mutex instead of a spinlock.
* The vm_translation_map is now correctly held in all of the vm_ mapping
  functions.
* Removed the old vm_daemons.c file - there is now a new vm_daemons.cpp
  which contains the beginnings of our new page daemon.
  So far, it's pretty static and not much tested. What it currently does
  is to rescan all pages in the system with a two-handed clock algorithm
  and push pages into the modified and inactive lists.
* These inactive pages aren't really stolen yet, even though their mappings
  are removed (ie. their next access will cause a page fault). This should
  slow down Haiku a bit more, great, huh? :-)
* The page daemon currently only runs on low memory situations, though.

Axel Dörfler b50494aaac * file_cache_set_size() now calls file_cache_invalidate_file_map() with the
correct values (resolving a TODO); however, the latter doesn't do anything
  with those yet.
* Cleanup.

Axel Dörfler 8a3cfa2cf3 * Made menu windows behave differently than others: before, they were just
always put between window screens and modal all windows (before floating
  all ones), so a BWindowScreen couldn't have menus at all.
  Now, they behave more like floating app windows, just that they float above
  all other application windows, such that all window feels (also BWindowScreen)
  can now have menus.
* Reenabled keyboard redirection to the top most window in case it's a menu;
  bug #1152 no longer applies due to the above change.
