USB: Acquire the device manager lock before Explore.

We must do this to prevent lock order inversion: when busses are
initialized, they are started by the (locked) device manager, and
then acquire the explore lock. We must do the same in Explore itself,
for when called by the explore thread, we would otherwise first acquire
the explore lock, then (when publishing new nodes) acquire the device lock.

Should fix #18421 and #18393.

USB: Do not wait for first explore in Stack constructor.

Following various refactors, at the point the Stack object is created,
there are no bus managers yet, so exploring will find nothing.

usb: explore on BusManager::Start()

registering new devices requires the device_manager lock. The explore thread would wait
that the initial device scan is over to register devices.

USB: Track object busy-ness and wait for an unbusy state before teardown.

This reverts and replaces hrev53141, hrev53200~1, and hrev53888.

Two years ago (in hrev53141), I added checks to validate that Devices
were not in the process of being torn down before using them, to fix
a race condition KDL. Further logic was added in hrev53200~1 and in
hrev53888 for Pipes.

Well, upon closer inspection following the reports of #16794 et al.,
it appears upon closer inspection there were still two more race
conditions lurking in there: the first between Get and InitCheck, and
the second between InitCheck and use.

To resolve both of these, a new atomic "busy" flag is added to objects,
which is incremented before unlocking the objects array, and then
waited on before actually proceeding with teardown.

The older checks about initialization status are now superfluous
and are removed in favor of an earlier PutUSBID() invocation in Device.

While #16794 was fixed by hrev55429, some of those or related KDLs
might have been caused by these races. This also re-resolves #15115,
along with #14949 and #15710.

Replaced B_32_BIT_MEMORY by B_32_BIT_FULL_LOCK and B_32_BIT_CONTIGUOUS, so

* Added simplified possibility to schedule UHCI transfers from within KDL.
* Added debugger commands to resolve usb_ids to pipes.
* Adjusted the physical memory allocator to be usable in a slimmed down mode
when running inside the kernel debugger.
* Implemented USB keyboard support for KDL through a kernel debugger add-on.
* Added kgetc() and made use of it where previously individual methods were used
to ensure that reading characters always goes through the kernel debugger
add-ons and the other methods.

This has some preconditions to meet though:
1) The keyboard must be in the boot protocol (currently the case but needs to
be revisited once we have a full usb_hid).
2) The keyboard must be attached to a UHCI root port (i.e. not use EHCI or OHCI,
also not through hubs unless those are USB 1.1).
3) the usb_hid driver has to be opened for this to work. This means that for the
time between initializing USB and when usb_hid is opened by the input_server
there is no keyboard support.

Also note that this has no way of detecting hot-plug, meaning that you can't
re-attach your USB keyboard from the hub to the root port once in KDL.

On the bright side of things, since this is a non-destructive mechanism it is
possible to enter and leave KDL without loosing the USB state.

Tested OK in QEMU, not tested on real hardware yet, will see in a few minutes.

trace output from devices across multiple controllers distinguishable.

* Fixed a ton of wrong usages of B_CONTIGUOUS + B_FULL_LOCK.
* 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.

Use a list of host controller modules instead of using open_module_list() and
read_next_module_name(). This is ugly and less flexible but it allows us to
explicitly force an initialization order. As detailed by the added comment
there seem to be controllers/BIOSes that require the EHCI controller to be
initialized after the companion host controller or else they refuse to publish
any high speed devices. This was the case for bug #1236 and my laptop when
legacy emulation is enabled and any device was plugged in at boot. This change
fixed the problem for me and hopefully closes bug #1236 too.

Completely redesign the USB explore process. Replaces the scary race conditions of the previous locking mechanism and simplifies handling of device changes by a more centralized approach.
Changes are now collected during explore and notifications as well as rescans are done at once. Through this a driver is also not rescanned multiple times anymore.

Also wrote a memory allocator that takes over memory management from the stack. It is similar to a buddy allocator. This does on the one hand remove some ugly code from the stack and is on the other hand far more scalable than the previous free list approach. This scalability is needed for proper EHCI support where buffers can go up to a size of 5 pages. The allocator is not perfect and it's memory overhead is quite high compared to the managed memory (depends on the managed block sizes), but it's quik and works well so far.

This is just an outline of the USB stack: what it is going to look like. It is definately not
ready for testing. Also the documentation is far from complete (it's in it's early phases).
Unfortunately I don't have enough experience in hardware programming to prototype
it first, so I'll be testing the things that I design in the document.

Poll more frequently for the first explore.

This reduces needless waiting for the special case of the polled and
synchronous first explore.

Get USB functional on x86-64.

- Various changes to printf format specifiers to make them 32/64 safe.
- Adjustments to various descriptor structures since addr_t is not 32-bit
on x86-64, and consequently this breaks the physical structure that's
expected. Also adjusted padding to accomodate 32-byte boundaries when
64-bit pointers are in use.
- Adjustments to make use of phys_addr_t where needed.

Fix uninitialized fAllocator member. In the error case the destructor could
crash trying to delete the not created allocator. CID 9562.

Replaced B_32_BIT_MEMORY by B_32_BIT_FULL_LOCK and B_32_BIT_CONTIGUOUS, so
the constraint can be expressed more precisely. ATM B_32_BIT_FULL_LOCK is
implemented as B_32_BIT_CONTIGUOUS when B_HAIKU_PHYSICAL_BITS > 32, though.

Force allocation of physical memory < 4 GB until the related TODOs are fixed.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37201 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed physical_entry::{address,size} to phys_{addr,size}_t and changed
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.

* Rename usb_p.h to usb_private.h.

* Added simplified possibility to schedule UHCI transfers from within KDL.
* Added debugger commands to resolve usb_ids to pipes.
* Adjusted the physical memory allocator to be usable in a slimmed down mode
when running inside the kernel debugger.
* Implemented USB keyboard support for KDL through a kernel debugger add-on.
* Added kgetc() and made use of it where previously individual methods were used
to ensure that reading characters always goes through the kernel debugger
add-ons and the other methods.

This has some preconditions to meet though:
1) The keyboard must be in the boot protocol (currently the case but needs to
be revisited once we have a full usb_hid).
2) The keyboard must be attached to a UHCI root port (i.e. not use EHCI or OHCI,
also not through hubs unless those are USB 1.1).
3) the usb_hid driver has to be opened for this to work. This means that for the
time between initializing USB and when usb_hid is opened by the input_server
there is no keyboard support.

Also note that this has no way of detecting hot-plug, meaning that you can't
re-attach your USB keyboard from the hub to the root port once in KDL.

On the bright side of things, since this is a non-destructive mechanism it is
possible to enter and leave KDL without loosing the USB state.

Tested OK in QEMU, not tested on real hardware yet, will see in a few minutes.

* Rework the USB tracing mechanism. Cleaned it up and make it more convenient to
use. It will now print out the usb_ids of the objects that generate the trace
messages. These IDs are unique compared to the device address used previously,
because device addresses are per bus while usb_ids are global. This makes
trace output from devices across multiple controllers distinguishable.
* Some cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29002 a95241bf-73f2-0310-859d-f6bbb57e9c96

* CID 7: The fObjectArray that holds the usb_id to object association was never
freed.
* Also the allocation of said array was not checked.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27455 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The USB bus manager was leaking unused bus modules.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27134 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed a ton of wrong usages of B_CONTIGUOUS + B_FULL_LOCK.
* 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.

* Make the maximum port count a define and set it to 16. OHCI officially
supports up to 15 ports and QEMUs OHCI emulation uses a port count of 10
for example.
* Update the hub code to remove the hardcoded 8 port limits.
* Some other code to enumerate the USB structure I had laying around
(available internally only, might be added as a public API some time).

Use a list of host controller modules instead of using open_module_list() and
read_next_module_name(). This is ugly and less flexible but it allows us to
explicitly force an initialization order. As detailed by the added comment
there seem to be controllers/BIOSes that require the EHCI controller to be
initialized after the companion host controller or else they refuse to publish
any high speed devices. This was the case for bug #1236 and my laptop when
legacy emulation is enabled and any device was plugged in at boot. This change
fixed the problem for me and hopefully closes bug #1236 too.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24926 a95241bf-73f2-0310-859d-f6bbb57e9c96

Change just host_controller_info to usb_host_controller_info for the sake of
clearity as suggested by Philippe Houdoin once and brought to my attention by
Slavatore. As this definition is completely private to the USB stack it would
not have caused any conflicts though.

* Use the rescan function when compiled for Haiku
* Move waiting for the first explore to complete
* Small cleanup

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23099 a95241bf-73f2-0310-859d-f6bbb57e9c96

Completely redesign the USB explore process. Replaces the scary race conditions of the previous locking mechanism and simplifies handling of device changes by a more centralized approach.
Changes are now collected during explore and notifications as well as rescans are done at once. Through this a driver is also not rescanned multiple times anymore.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22929 a95241bf-73f2-0310-859d-f6bbb57e9c96

Change the way notify hooks and rescans are handeled. The rescans are now delayed to after all notify hooks are called (like in BeOS).
This also ensures that the rescans do not happen while the devices are not yet added or already removed.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21905 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Moved around some initialization to avoid problems when deleting incompletely created objects
* Also move waiting for the first explore to run through out of the constructor to reduce delays
* Remove the old device when a new one is connected to the same port - this could happen when you very quickly un- and replug a device

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21042 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed a memory leak.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20752 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Revised locking of the USB stack classes
* Implemented the Hub destructor to properly free all of its child devices
* Added FreeDevice() and FreeAddress() to the BusManager class
* Added timeout to ControlPipe::SendRequest()
* Changed how the recursive device reporting works so that it respects the support descriptors of a driver
* Enabled driver rescanning for drivers that are not currently loaded but still registered (R5 only as the devfs function is yet missing from Haiku)
* Changed the way usb_ids are handed out so that free ones are reused instead of just running out of ids
* Fixed driver registration so that each driver is only added once (and devices are reported once per driver)
* Unified debug output and fixed some warnings with debug output turned on
* Fixed some style issues and removed stray whitespaces

Overall the USB stack should now be much more reliable. It should not crash on disconnects anymore and repluging of a device should be noticed by all drivers.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19860 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added some more debug output to the hub code
* Report and clear yet unhandled port changes in hubs
* Fixed the way devices that vanish on port reset are handled
* Added a status field to the memory allocator and check it creating it

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19732 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Moved and unified the explore threads from the BusManager to the Stack
Now there is only one explore thread instead of one per BusManager.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18981 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixing my previous attempt at fixing cookie handling. Device addresses cannot be used, since there may be devices with the same address across different busses. A linked list of usb_driver_cookies is maintained now that relates devices and cookies.
* Fixed endpoint halt clearing. The data toggle has to be reset when we clear a stall.
* Now using up to B_PAGE_SIZE * 4 sized buffers in EHCI. They are split automatically by the host controller. This further pushes throughput.
* Optimize memory allocator settings for the above case. Enlarging it's managed space to 1MB
* Ignore the transaction error bit in EHCI. It is only of informational character as it also idicates errors that were recovered automatically. If an unrecoverable error occures, other bits will indicate this.
* Fixed some more print formats in debug output.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18915 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed notify cookie handling. There is not one cookie per device, but one per device/driver combination
* Fixed SetFeature/ClearFeature/GetStatus for interfaces by adding the respective interface number
* Added driver rescanning mechanism (taken from bin/rescan)

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18912 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented most qTD and qH functions for EHCI async transfers.
* Implementing control and bulk (async) transfers. They don't work yet though.
* Corrected the legacy support handling in EHCI
* Fixed the bit mask for total bytes in qTDs and added the data toggle bit
* Changed the boolean low speed flags to usb_speed enum that allows for low, full and highspeed

Also wrote a memory allocator that takes over memory management from the stack. It is similar to a buddy allocator. This does on the one hand remove some ugly code from the stack and is on the other hand far more scalable than the previous free list approach. This scalability is needed for proper EHCI support where buffers can go up to a size of 5 pages. The allocator is not perfect and it's memory overhead is quite high compared to the managed memory (depends on the managed block sizes), but it's quik and works well so far.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18849 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Corrected some errors I found while reading UHCI.

* Added USB API Version 3. It's put into USB3.h while the v2 API resides in USB2.h. USB.h just includes USB2.h for now.
* Rewrote both headers on the way.
* The usb module now exports both, the v2 and v3 module_info.
* Changed the internals of the USB Stack to give out usb_ids instead of opaque handles to internal classes.
* Cleaned up some more of the Stack by moving members into other classes and removing unused stuff.
* Updated the usb_raw driver from v2 to v3 API.

Since both usb_hid (which still uses the v2 API) and usb_raw (which now uses the v3 API) work, I'd call it a success ;-)

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18539 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented a usb_ioctl to retrive the logical device name (like 0/0, 0/1/0 or 1/hub) that will be used by usb_raw to publish the according devfs entries.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18515 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed the Stack lock to a benaphore
* Removed some debug output from UHCI
* Added some debug output to the usb module instead ;)
* Rewrote the way new devices are attached and ports are handled (now more similar to FreeBSD)
* Corrected handling of port resets so that they should work on hubs too
* Cleaned up some headers

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18499 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented most of the USB module public API (using opaque handles like in R5 will change that to using IDs later)
* Fixed the UHCI root hub and the hub implementation. Interface and endpoint descriptors are part of the configuration descriptor, they cannot be requested individually.
* Added simple support for interrupt and bulk transfers to UHCI. It's enough to get my USB mouse working to a stable and usable degree.
* Cleaned up and reworked some other parts, added allocation checks and such.

Yes, my internet connection is back up :)

This is just an outline of the USB stack: what it is going to look like. It is definately not
ready for testing. Also the documentation is far from complete (it's in it's early phases).
Unfortunately I don't have enough experience in hardware programming to prototype
it first, so I'll be testing the things that I design in the document.
