USB: Use BStackOrHeapArray in RegisterNode.

I saw in a KDL stack trace that this function was using over 4KB of stack.
As it is called as part of device_manager startup, where there can be
pretty deep recursion happening, that seems like a bad idea.

Additionally, it did not actually do bounds checking.
Now we dynamically allocate an array of sufficient length.

USB: node unregistering returning B_BUSY is not a error in this case

USB: Split WaitForUnbusy from Object::PutUSBID.

In a few instances, we need to not wait for objects to become unbusy
during ID puts because we expect they still will be, e.g. in the case
of Control pipes with submitted transfers that are still running. There,
we need to put the ID, cancel transfers, and only then wait for the
object to become unbusy.

Technically, this is a functional change, but at least in practice
it will have little real-world effect, for two reasons:

1. The DefaultPipe's Busy flag is basically never updated (the Device's
busy flag is generally used instead), so it will virtually never be
"busy".

2. Most devices have no Control endpoints besides that default one.

USB: Put the default pipe's USB ID and cancel its transfers earlier during teardown.

This way, any endpoints or interfaces which are currently using the
default pipe for SetFeature/.../etc. will return immediately and
become unbusy.

Should fix the remaining KDLs in #16794 and #16969.

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.

USB: Rename USB_SPEED_SUPER to USB_SPEED_SUPERSPEED.

For consistency's sake with the others.

USB: Check and set the Device object state appropriately.

The Device object gets an ID before it begins initializing, and
loses its ID after it fully finishes tearing down, so simply
verifying the Device object is non-NULL is not enough to verify
that we can use it. We need to call InitCheck() every time.

In Device itself, we should also unset fInitOK when beginning
teardown, so that anyone who still has a handle can no longer
use this Device object while teardown occurs (which, depending
on the number of pipes, pending transfers, etc. may take some
time.)

Fixes #14949 and almost certainly any other USB-related KDLs
in these codepaths.

USB & XHCI: Refactor endpoint initialization to support SuperSpeed better.

SuperSpeed (USB3) devices have a "companion descriptor" along with the
endpoint descriptors that describes certain other attributes they have,
which are important for the controller to schedule transfers properly.
Previously we were just using USB2 values; now we are properly using USB3
ones.

Tested on an Intel Lynx Point controller. As far as I can tell, no
regressions, but #15000 is not fixed anyway.

usb: fixed potential crash.

* The active interface may be null. This actually happens with a Lasmex
USB speaker in case it is turned on.

usb: coding style cleanup.

* Removed a few superfluous comments, too.

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.

Work in progress on xHCI bus driver.

* added more traces, coding style
* added xhci_td, xhci_endpoint structs.
* SubmitRequest: this links a 3-stage TD control request into

* _InsertEndpointForPipe: when a pipe is created, configure the
endpoint and set up the controller cookie.
* CreateDescriptor and FreeDescriptor: allocates memory for a TD.
* _LinkDescriptorForPipe: link a TD in an endpoint ring.
* _UnlinkDescriptorForPipe: unlink a TD
* AllocateDevice:

configure the default endpoint before calling SetAddress.
address is found in the device context instead of the input context.

* Fix off-by-one error in port number which caused full- or lowspeed devices
behind highspeed hubs with multiple transaction translators not to work.
* The parent hub isn't necessarily the one providing the transaction translator
for a full- or lowspeed device. Therefore we need to inherit the hub/port
addresses to lower devices unless we are a highspeed hub that might be the
actual provider of the transaction translator. This logic error caused full-
and lowspeed devices not to work if they were behind a fullspeed hub that
itself was behind a highspeed hub.

* 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.

* Don't inherit Device and Interface from pipes anymore. The device has a default pipe member now.
* Since the parent of each Object is now known, we can send control messages using the default pipe of the device from all attached elements (pipes and interfaces).

usb: fixed potential crash.

* The active interface may be null. This actually happens with a Lasmex
USB speaker in case it is turned on.

usb: coding style cleanup.

* Removed a few superfluous comments, too.

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.

Work in progress on xHCI bus driver.

* added more traces, coding style
* added xhci_td, xhci_endpoint structs.
* SubmitRequest: this links a 3-stage TD control request into
the endpoint ring.
* _InsertEndpointForPipe: when a pipe is created, configure the
endpoint and set up the controller cookie.
* CreateDescriptor and FreeDescriptor: allocates memory for a TD.
* _LinkDescriptorForPipe: link a TD in an endpoint ring.
* _UnlinkDescriptorForPipe: unlink a TD
* AllocateDevice:
slot number zero isn't valid.
stick the slot number to the device struct.
configure the default endpoint before calling SetAddress.
address is found in the device context instead of the input context.
device address passed to the USB stack has to begin with 1.
* Ring:
check for invalid slot/endpoint combination.
ring the slot doorbell instead of the doorbell 0.
* Root hub: fixed USB version.
* HandleTransferComplete: finds out the TD which submitted a
transfer.

Tiny cleanup.

* Work around a problem with a USB device (in my case, Qualcomm Gobi 3G modem) that reports interface_number values that are out of range with the interface_count. This would make the usb stack in Haiku crash.

Will need a different fix to get device to work, but at least Haiku won't crash on bootup with this change.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37409 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Rename usb_p.h to usb_private.h.
* Some automatic whitespace cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36247 a95241bf-73f2-0310-859d-f6bbb57e9c96

No need to crash if we are deleted after not getting far enough to allocate the
configuration buffers.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33122 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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

Check the allocation of the endpoint pipe object.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27457 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fix off-by-one error in port number which caused full- or lowspeed devices
behind highspeed hubs with multiple transaction translators not to work.
* The parent hub isn't necessarily the one providing the transaction translator
for a full- or lowspeed device. Therefore we need to inherit the hub/port
addresses to lower devices unless we are a highspeed hub that might be the
actual provider of the transaction translator. This logic error caused full-
and lowspeed devices not to work if they were behind a fullspeed hub that
itself was behind a highspeed hub.

This fixes bugs #1889 and #2501.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26552 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Clear the configurations list so it can safely be handled in case the device
fails to init completely.
* Fix wrong usage of realloc and check the allocations.
* Check a few more allocations, should be all now.
* Fix a small memory leaks in error case.
* Do a few more checks when unconfiguring and deleting a device so an incompletely
initilized device is deleted correctly and does not crash or leak.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25654 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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).

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25555 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Clear the endpoints of an alternate interface that is going away before
updating the active pointer as otherwise the endpoints of the new alternate
would have been cleared instead of the old one (leaking endpoints).
* Only clear and re-initialize the endpoints of the interface we are setting
an alterntate. Otherwise we tear down all the device endpoints which would
result in a bad situation for composite devices where multiple drivers may
use different functions (through different interfaces) of a device side by
side.
* Minor cleanup.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25432 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Another tiny cut in stack load time: do not delay after setting the current
configuration of a root hub
* Cut down on number of retries to set the initial device address

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24804 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added SetAltInterface method which allows to set an alternate interface for the device
* Added InitEndpoint and ClearEndpoint to avoid code duplication
* Usual clean up


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22983 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Redesign the Pipe constructor to only take the parent object
* All other init is done in InitCommon() which only needs to be present in the base class
* Adding the hub port a device is attached to to the Device class
* Add hub port and hub address to the Pipe class (will be used for split transactions in EHCI)
* Update the root hubs to reflect the changes to hub creation

Sadly we need pipes that do not belong to devices (default pipe for addressing and to get initial device descriptor). Therefore we cannot resolve hub address and port from the parent device.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22972 a95241bf-73f2-0310-859d-f6bbb57e9c96

Store the polling interval in the InterruptPipe class to make it accessible to the controller.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22936 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

Initialize the endpoints of all interfaces of the configuration to be set. Fixes stuff that needs more than one interface at the same time (ACM modems for example).

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21741 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed wrong deallocation of device resources which caused KDL when unplugging devices with more than one interface.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21038 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed a wrong index that could cause crashes with devices containing generic descriptors

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19969 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

* Fixed device creation. No pipes for device endpoints are created and the initial handle of all endpoints is 0.
* The endpoint pipes of a configuration are now created when the configuration is actually set.
* Implemented an Unconfigure() function that tears down any pipe that was created for that configuration.
* Implemented the device destructor that unconfigures and frees the resources allocated for the various usb_*_info structures.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18952 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

* Rewrote some stack internals (again). Everything is now created using a parent object that shares the BusManager and Stack information to reduce individual constructors.
* Don't inherit Device and Interface from pipes anymore. The device has a default pipe member now.
* Since the parent of each Object is now known, we can send control messages using the default pipe of the device from all attached elements (pipes and interfaces).
* Fixed the generic {Set|Clear}Feature() and GetStatus() calls to include the endpoint address for pipe specific requests.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18710 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Redisigned some of the USB Stack. Unified constructors, removed redundant functions and moved some other functions around
* Implemented the EHCIRootHub
* Reworked UHCIRootHub to be more of a utility class and moved the actual work into the UHCI BusManager
* Implemented port reset in EHCI. Ports with low and fullspeed devices are now correctly handed over to the companion host controller.

Attachs and detachs as well as port resetting / enabling works now in EHCI. Only the actual data transfers are missing thereafter ;-)

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18656 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Unified and disabled TRACEing for the usb stack and uhci hcd
* Fixed warnings
* Some cleanup
* Added myself as an author to some files

No functional changes.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18614 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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

* Fixed setting configurations (need to use the configuration_value instead of the index of course)
* Fixed reported power status of the UHCI Root Hub
* Added preservation of the SOF_MODIFY register when doing a global reset of the UHC
* Read out the actual length for outgoing transfers too
* Made actual length handling for transfers a bit safer and correct in respect to NULL packets
* Use short packet detect to handle short packets
* First step at implementing the hub interrupt

Since the devices are now configured correctly, some bulk transfers actually work. Also my hub now reports its status correctly.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18506 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 :)

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18496 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Calmed down debug output a bit
* Removed all friends in the USB stack classes (as they are not needed)
* Added max packet size to the pipe and respect it on transfers
* Use pipes with the same speed as the device

Device descriptors can now also be retrieved from full speed devices and devices with a packet size of more than 8 bytes. The devices are also correctly initialized to their default configuration.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17639 a95241bf-73f2-0310-859d-f6bbb57e9c96
