* Create new interface for cpuidle modules (similar to the cpufreq
interface)
* Generic cpuidle module is no longer needed
* Fix and update Intel C-State module
* virtio_scsi can have 16384 luns, though we cap at 256 as our scsi_ccb
only uses uchar as a type for target_lun and target_id members.
* minor code cleanup in scsi_scan_bus().
* The UNMAP command is theoretically much faster, as it can get many block
ranges instead of just a single range.
* Furthermore, the ATA TRIM command resembles it much better.
* Therefore, fs_trim_data now gets an array of ranges, and we use SCSI UNMAP
to trim.
* Updated BFS code to collect array ranges to fully support the new
fs_trim_data possibilities.
* No need for the atomically changed variables to be declared as
volatile.
* Drop support for atomically getting and setting unaligned data.
* Introduce atomic_get_and_set[64]() which works the same as
atomic_set[64]() used to. atomic_set[64]() does not return the
previous value anymore.
Finishing and refactoring the draft, initially implemented during April-May 2012
NOTE: startingFrameNumber returned to device contains the number of the
next free frame right after the last packed of submitted data. For more
details please Look into corresponding [haiku-development] discussion
started at 03 Jul 2013.
Partially fixes#1045.
devfs_io() can't fall back to calling vfs_synchronous_io(), if the
device driver doesn't support handling requests asynchronously. The
presence of the io() hook leads the VFS (do_iterative_fd_io()) to
believe that asynchronous handling is supported and set a
finished-callback on the request which calls the io() hook to start the
next chunk. Thus, instead of iterating through the request in a loop
the iteration happens recursively. For sufficiently fragmented requests
the stack may overflow (ticket #9900).
* Introduce a new vnode operation supports_operation(). It can be called
by the VFS to determine whether a present hook is actually currently
supported for a given vnode.
* devfs: implement the new hook and remove the fallback handling in
devfs_io().
* vfs_request_io.cpp: use the new hook to determine whether the io()
hook is really supported.
* The config space is larger than 255, we need to use an uint16 to access
offsets superior or equal to 256. The current API only proposes an uint8 for this.
This change switches the offset parameter to the uint16 type. Axel hinted that
the used values are the same with such a change (the doc says sign extended to 2 or
4 bytes).
I checked with GCC2 and it's indeed the case when inspecting the memory.
With GCC4, instructions are the same on function call.
* prints info about extended capabilities.
* struct pci_module_info and struct pci_device_module_info are extended with
pci_find_extended_capability().
After this change, low level cpuidle drivers load the generic cpuidle
module if they can support the underlying platform.
change the intel cpuidle driver accordingly, now it's loaded by acpi
bus manager during boot, although it doesn't depend on acpi

This module will load the various lowlevel cpuidle modules' implementations
during initialiation. If it finds one available module, it will change
the global gCpuIdleFunc as its own better one.
When idle, cpuidle module will select the best cstate and enter it by
calling the lowlevel module's implementation.

This module provides an interface for drivers to use to perform calls
to the BIOS (only really for use by graphics drivers which need to use
the VESA BIOS). It uses the x86emu library from X.org which emulates
a real mode x86 CPU. This is necessary for x86_64 as virtual 8086 mode
no longer exists there.
Uses the x86 architecture code, made fixes to printf formats and a
couple of 64-bit fixes. Only potentially intrusive change is that I've
changed PCI.h to use uint32 rather than ulong. I don't see any way
this would cause any issues, though.
Haiku implements file locking at vfs level. That would not work for remote
and shared file systems, since they need to negotiate locks with peers.
This patch introduces three additional hooks in fs_interface that allow
file system module to take over the management of file locks.
recv on UDP sockets is not interrupted when the socket is closed.
Additionaly, signals do not interrupt kernel threads, that is why
new function interrupt_thread was implemented in order to cancel
listener thread.
I commited... need to get back into the habbit, sorry for the noise.

See http://www.acpica.org/download/changes.txt done after 2010-10-13 for info on ACPI changes.
* Adapted the embedded controller to match current FreeBSD one.
There will probably be some issues with these changes initially.

available as a module function as well.
* Remove some unneeded resetting from tty_destroy_cookie.
* Move the public module functions to the public API section of the file and
order them by their declaration order in the module info.

partition_module_info::uninitialize().

* Implemented KFileSystem::Uninitialize().
Fixes failure to initialize a BFS initialized device with an intel partition
map.

turns out to be flaky, is a little bit of a hack anyway and performs unnecessary
operations. The functionality is now handled kernel side which optimizes those
problems away.

the base bus number and segment which is what we're using them for. It should
work generically, however I only tested it to look up PCI bridge devices.
The logic is a subset of what is done in AcpiEvPciConfigRegionSetup when setting
up the operation region for a PCI device.

the cached pci_info and writes the new value into PCI config space. Drivers
using either mechanism to enumerate devices will therefore get the updated
value.

drivers in the future, such that NetworkStatus and similar software can show
nice names for the devices. The device manager should implement this and
return the B_DEVICE_PRETTY_NAME of the device (and in turn, new style drivers
should actually set this).
* Implemented handling of this ioctl in the scsi_periph to return the vendor/
product strings.
* Implemented this in the ATA bus manager to return the model from the info
block.
* KDiskDevice now fills in the partition_data::name if the B_GET_DEVICE_NAME
succeeds.
* As a side effect, at least BootManager now shows the drive name; maybe
DriveSetup does as well for the raw device.

* A lot of HID definitions got extracted from USB_hid.h into their
own files. Many more definitions have been added from the specs.
* The names have been moved into the proper B_* namspace.
* The USB hid driver has been adapted for the changes.
Thanks a lot and sorry for the delay!

and doesn't come with BeOS backwards compatibility. It also has the BeOS
compatibility ioctl ops removed and such. I've actually made this back in april,
so I don't really remember any more details.

Embedded Controller still needs some looking into, and I had to remove the WIP code for dumping MADT.
Both are on my TODO.
Also removed a lot of unneeded parts of ACPICA from trunk and did some cleanup in Jamfile.

restrictions for virtual/physical addresses.
* vm_page_allocate_page_run():
- Fixed conversion of base/limit to array indexes. sPhysicalPageOffset was not
taken into account.
- Takes a physical_address_restrictions instead of base/limit and also
supports alignment and boundary restrictions, now.
* map_backing_store(), VM[User,Kernel]AddressSpace::InsertArea()/
ReserveAddressRange() take a virtual_address_restrictions parameter, now. They
also support an alignment independent from the range size.
* create_area_etc(), vm_create_anonymous_area(): Take
{virtual,physical}_address_restrictions parameters, now.
* Removed no longer needed B_PHYSICAL_BASE_ADDRESS.
* DMAResources:
- Fixed potential overflows of uint32 when initializing from device node
attributes.
- Fixed bounce buffer creation TODOs: By using create_area_etc() with the
new restrictions parameters we can directly support physical high address,
boundary, and alignment.

map_physical_memory()'s physicalAddress parameter type from void* to
phys_addr_t. This breaks source compatibility, but -- as long as
phys_{addr,size}_t remain 32 bit wide -- keeps binary compatibility with
BeOS.
* Adjusted all code using the affected interfaces (Oh what fun!). Added a few
TODOs in places where the wrong types (e.g. void* for physical addresses
are used). Looks like quite a few drivers aren't 64 bit safe and others
will break with PAE.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36960 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed irq_routing struct from ACPI.h to where it is used. Might be able to use acrestype.h instead of duplication.
* Disable old embedded controller and remove it from image.
* Move embedded controller code to busmanager module.
* Remove (some) code duplication
Should work as before, but is now initialized right after the bus manager. Can probably remove further code duplication.
I hope I've done it correctly, feedback is most welcome.

* Exposed ACPI API needed by Embedded Controller
This will be removed again if moved inside the bus manager.
It also duplicates ACPI's own headers so it might go out of sync atm.
* Added mutex to controller and fixed the mixup between acpi_status needed in int handlers and Haiku status.
* Major code cleanup
Not for headers as they are mostly redundant if we move the controller.
Variable names still needs some cleanup
This makes the ACPI errors from the controller understandable. I get AE_NO_HARDWARE_RESPONSE now.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36318 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implement such a module for x86 which currently exports only an MSI API.
* Implement the PCI part for configuring and enabling MSIs.
* Some automatic whitespace cleanup.
