- Added skeleton code for setting device mode.
- Next, figure out which bits to set!

the dirent buffer. This fixes Rene's comment about "ls" entering an endless
loop.
* It also didn't access the buffer passed in correctly if it came from userland.
* It now also fills in as many entries in the buffer as fit.

* dir_read() now takes into account that we may have read more than one dir
entry, and calls fix_dirent() for each of them.

* The use of B_{READ|WRITE}_AREA throughout the drivers is surely alarming.
Defining these flags means that *every user* application can access these
buffers read/write, it becomes visible in userspace like any other memory
(just shared among all apps). I would like to ask each driver maintainer
to see if that is really wished here. If you only need one app to be able
to access it, cloning the area would be more appropriate.
* I came across the use of B_ANY_KERNEL_BLOCK_ADDRESS a number of times. This
is almost completely useless for most usages, as it tries to align the
virtual to a multiple of the size of the area. It just makes the allocation
more likely to fail. Please only use where appropriate, and please review
your code.
* Minor cleanup.

* Moving common functions and macros used in realtime_sem_test1
to a shared header as they are probably going to be used for other test unit

cut down the buffer size on the last request. This fixes bug #2565.
* cdda_read() did report an incorrect number of bytes read. This fixes bug
#2511, and also that you couldn't copy tracks via "cp".
* cdda_read_stat() did not include the WAV header in its reported size.

* If a segment violation occurs, we do now check whether the thread in
question has a handler for SIGSEGV. If so, we just send it the signal.
Otherwise we notify the debugger as before.

the cache locked, since it enters the VFS and might reenter VMCache,
thus causing deadlocks. Fixes bug #2577.

* On Haiku, this will make them disappear from the results list.
* On BeOS, it will only work around the problem that we don't know
which file was removed from the node monitoring message...
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26848 a95241bf-73f2-0310-859d-f6bbb57e9c96
* use HDAC_STREAM_POSITION register value to check the current buffer cycle in interrupt handler
* added B_FULL_LOCK flags for area allocation, not sure it's handled but at least more correct
* buffer descriptors now use a low and high address fields
* applied a byte mask on format
* enabled PCI bus mastering if not yet done
* the PCI space register TCSEL (Traffic Class Select Register, which sets PCI express QOS) is now reset to TC0 (clear 0-2 bits) as needed on some boards like mine to
ensure good playback
Playback is finally working correctly here on ICH8 HDA!

- Removed most of the currently fixup code as, at least on my machine,
it was messing stuff up. This makes the PATA controller work in IDE
mode!
- Added comments to clarify things and TODOs about what is still missing
(specially getting AHCI mode working).
Marcus, please review.

then be used for receiving node monitoring messages.
* Reenabled using be_app as default BLooper if the API user does not provide
one. I think the problem that Stefano needed to work aroung in r23995 was
actually caused by the incorrect locking (an never unlocking) of the looper
before calling PathHandler::Quit().
->If I understand correctly, this code as supposed to work around the possible
situation that the looper holding those PathHandlers may have already quit,
leaving stale PathHandler pointers behind. But that case was not prevented
by the old code anyways, since one would have had to access freed memory to
even get the stale BLooper pointer. The real fix would be to store the
BLooper pointer with each PathHandler so that the possible gone-ness of
those loopers could be checked independent of accessing the PathHandler
pointer. (The whole problem is that PathHandler adds itself to the BLooper
and if the looper quits, it will free all its attached handlers.)
* Introduced a global fallback BLooper for the case that no BApplication is
running, which resolves a TODO.
All this is yet untested, but should have a good chance of working.
(Famous last words...)

- Better adhere to style guide.
- Remove superfluous check for device function before setting IRQ.
- Added comment about setting IRQ for device with function 1.
- This fixes nothing yet, in case you are wondering. :)
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26842 a95241bf-73f2-0310-859d-f6bbb57e9c96
fixed. Not sure why the 6 to 10-byte command translation was triggered,
though.
* Minor coding style changes.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26840 a95241bf-73f2-0310-859d-f6bbb57e9c96
dedicated functions.
* Introduced gMappedPagesCount variable which counts the total number of
physical pages that are mapped.
* Added vm_page_get_stats() which fills in the memory related part of
the system_info structure. Used and cached pages are computed
differently, now. The "available" (== not committed) memory is no
longer used for the computation as it doesn't say anything about the
actually used/free pages (with swap support enabled it is even
less meaningful, since we first commit swap space when possible).
We do also consider the memory used by the block cache as cached
pages, now. All in all these changes should fix the memory statistics
reported by get_system_info(), IOW bug #2574.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26837 a95241bf-73f2-0310-859d-f6bbb57e9c96
* This should have been part of r26828, although it did not break the build :-)
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26829 a95241bf-73f2-0310-859d-f6bbb57e9c96
architecture: for now, we do this on the lowest layer only, therefore all
requests are handled synchronously (ie. in the scheduler's thread).
* Instead of using the block_io module, scsi_disk (and scsi_cd) are now
exporting a device on their own, and use an I/O scheduler with an appropriate
DMA resource.
* There are still lots of TODOs, and it can easily panic - don't update if
you intend to demo Haiku.
* scsi_periph now only has an io() function that get an io_operation, instead
of the previous read/write functions, moved preferred CCB size from those
functions into the device registration.
* Changed all scsi_periph files to C++.
* scsi_cd ported, too, but untested.
* Removed block_io from image - it will be removed completely soon.
* Temporarily commented an ASSERT() in the ATA bus manager (in case you use
it); it's sometimes triggered by the code now, and I haven't yet looked into
the issue -- doesn't seem to harm, at least.

otherwise we end up in an endless loop. This only happened when
the remaining raw data provided did not contain enough content.
In this particular case there were only 2 bytes remaining though
the decoder needed 4 bytes to handle at least 1 frame. Seems like
the audio file only provided data for one channel in the end, which
did not lead to a B_LAST_BUFFER_ERROR yet as it has been read properly.
* This fixes bug 1708 and most probably 1275 as well (someone check and
close please)
Didn't we just have a discussion about Media handling killing the system
:P

reuse the block_io attributes in the node to build the dma_restrictions.
* DMAResource::Init() now dumps the dma_resources (should be done with the
TRACE() macro later).
* Turned off IOScheduler debug output.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26825 a95241bf-73f2-0310-859d-f6bbb57e9c96
* return error in case we could not get all values from JobConfig

include the guard pages. Adjusted the kernel and boot loader code
accordingly -- the guard pages size is added/not removed respectively.
The stack size passed to _kern_spawn_thread() is now the actually usable
size, and it is no longer possible to specify a size smaller than or
equal to the guard pages size.
* vm_create_anonymous_area(): Precommit two pages maximum -- a stack with
only one page usable size obviously doesn't need two pages.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26819 a95241bf-73f2-0310-859d-f6bbb57e9c96
* sync against the preview driver
* fixed totally broken multiple pages on single page preview
