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: Clarify that BusManagers do not really have usb_ids.

Instead their IDs are indexes into the stack, and are used primarily
for TRACE*() printing, so move the getter function into a "protected"
block and rename the variable appropriately.

USB: Properly assign IDs to USB Bus Managers (HCI drivers).

Previously they would just get -1, as the BusManager class
would request their ID before they had been added to the Stack.
Now we add them to the stack inside ::Start(), rather than letting
the individual drivers do that just after ::Start(), and then assign
the ID there directly.

USB: Generalize logic for debug transfers used within KDL.

Pull debug transfer methods into the base BusManager class and
implement them for UHCI and EHCI. This makes it possible to have a
single debugger command installed by the USB stack instead of HCI
specific ones.

Cleanup and some added constness.

* 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.

* 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.

* 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

Cutting down on unnecessary per-controller delays when starting up the USB
stack. The root hubs do not really need a powerup delay and as they are not
used until all initialization is done, this gives plenty of time to stabilize
the power. Therefore remove the powerup delay for root hubs and reduce the
stabilization time to zero. Also remove the define for the first explore delay
as it is not used.

* 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.

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.

Prepare cancelling transfers from the stack side. The actual handling will happen in the HCD modules where transfer management has to be done anyway.

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.

Improve/fix lazy pipe creation introduced in 19032 based on suggestions by Michael and Marcus.

Implement lazy pipe creation. The Default Pipes for each speed will be created as needed, instead off at the construction of the busmanager. This is due to the fact that the creation in the constructor would callback methods of the busmanager class which might cause improper behaviour with uninitialized variables.

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

* Implemented a notification method for BusManagers so that they can be notified of pipe changes (creation, destruction, changed settings).
This is necessary in OHCI and will probably be used in EHCI also to keep one endpoint construct for each pipe open instead on creating and deleting it for each transfer.
* Pseudo implemented set_pipe_policy for isochronous pipes that makes use of the new notification system.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18945 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.

* 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.

* 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 ;-)

* 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 ;-)

* 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

* 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 :)

* Added locking to the driver and the queues
* Added service thread for finished transfers (to be implemented correctly)
* Cleaned up some headers and added myself as author

* 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.

* Added debugging facilities
* Implemented the data stage of control messages

* Cleaned up / applied style to the Pipe class
* Introduced a Queue class that manages itself and where transfers are attached to
* Added "set feature" to the roothub and use it to enable the port of new devices

It is now possible to successfully detect new devices and send at least one transfer descriptor to them.

* Fixed some copy&paste errors I introduced earlier
* Removed the "one UHCI bus only" limit
* Other fixes

The hub now sees when a new device is connected but failes when getting its descriptor.

* The parent hub isn't necessarily the one providing the transaction translator

addresses to lower devices unless we are a highspeed hub that might be the

itself was behind a highspeed hub.

* 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

Cutting down on unnecessary per-controller delays when starting up the USB
stack. The root hubs do not really need a powerup delay and as they are not
used until all initialization is done, this gives plenty of time to stabilize
the power. Therefore remove the powerup delay for root hubs and reduce the
stabilization time to zero. Also remove the define for the first explore delay
as it is not used.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24727 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

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

Prepare cancelling transfers from the stack side. The actual handling will happen in the HCD modules where transfer management has to be done anyway.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21043 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.

Here's the Unlock ;-)

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19054 a95241bf-73f2-0310-859d-f6bbb57e9c96

Improve/fix lazy pipe creation introduced in 19032 based on suggestions by Michael and Marcus.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19034 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implement lazy pipe creation. The Default Pipes for each speed will be created as needed, instead off at the construction of the busmanager. This is due to the fact that the creation in the constructor would callback methods of the busmanager class which might cause improper behaviour with uninitialized variables.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19032 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

* Implemented a notification method for BusManagers so that they can be notified of pipe changes (creation, destruction, changed settings).
This is necessary in OHCI and will probably be used in EHCI also to keep one endpoint construct for each pipe open instead on creating and deleting it for each transfer.
* Pseudo implemented set_pipe_policy for isochronous pipes that makes use of the new notification system.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18945 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

* 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

Continuing work on the USB stack and UHCI driver.
* Moved the transfer descriptor management into the UHCI class
* Added locking to the driver and the queues
* Added service thread for finished transfers (to be implemented correctly)
* Cleaned up some headers and added myself as author

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18245 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed the debug output of the short descriptor and replaced remaining deviceNum with deviceAddress as that's what it is.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17640 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

Applying style to remaining classes. No functional change.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17624 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Moved the transfer descriptor handling to separate functions
* Added debugging facilities
* Implemented the data stage of control messages

The device descriptor can now be successfully retrieved. Now interrupt, bulk and isochronous data transfers need to be implemented.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17623 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Cleaned up / applied style to the Pipe class
* Introduced a Queue class that manages itself and where transfers are attached to
* Added "set feature" to the roothub and use it to enable the port of new devices

It is now possible to successfully detect new devices and send at least one transfer descriptor to them.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17615 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Cleaned up / applied style to the BusManager class
* Fixed some copy&paste errors I introduced earlier
* Removed the "one UHCI bus only" limit
* Other fixes

The hub now sees when a new device is connected but failes when getting its descriptor.
