pci: extend MSI interrupt vector number to 32 bits

Also increase MSI message data size to 32 bits according to PCIe spec.

Remove 0xff check for MSI interrupts because it is potentially valid
interrupt vector number. Reject 0xff only for legacy pin interrupts.

- MSI-X supports up to 2048 interrupts per device that do not fit to
`uint8`.

- Non-x86 systems may use separate interrupt vector ranges for
hard-wired interrupts and MSI interrupts so `uint8` is not enough to
represent all of them.

USB: Support physical-vector bulk requests.

Introduce a new utility method, "generic_memcpy", which takes
generic_addr_t plus indications of whether these specify virtual or
physical addresses (and potentially user addresess) and calls the
appropriate memcpy variant depending.

All bus drivers adjusted to support this at once. We don't actually
take advantage of the physical addresses in any way (yet), as USB
controllers have some pretty specific requirements that would have
to be carefully validated to use these directly.

All bus drivers tested and confirmed to still be working.

busses/usb: Move ::AddTo to be above the class constructors.

It is called before them (and is responsible for calling them),
so having it in the middle of the file does not make a lot of sense.

Already done for XHCI. Only one functional change -- removing the
set_dprintf_enabled call. Drivers probably shouldn't spuriously
re-enable that if it was specifically disabled.

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.

UHCI USB: add MSI support

* similar to OHCI support by mmlr.
* interrupt handler is removed on destruction.

Fixed UHCI for x86_64.

* Added arch_debug_blue_screen_try_getchar() and arch_debug_serial_try_getchar()
which don't wait for a character, but return -1 when no character is
available ATM. Implemented correctly for x86 only.
* Changed the semantics of the debugger_module_info::debugger_getchar() hook.
It is supposed to return immediately now.
* Adjusted usb_keyboard accordingly. Hacked UHCI's debug_process_transfer() to
achieve that. It does now start, check, or cancel a transfer. Split
UHCI::ProcessDebugTransfer() into StartDebugTransfer(), and
CheckDebugTransfer() accordingly, and also added a CancelDebugTransfer().
The latter seems to have issues. Michael, please have a look. I have no clue
what I'm doing. :-)
* Adjusted kgetc() to poll all possible inputs using the new
functions/semantics. This allows to use any input (USB, PS/2, serial) in KDL.
* Removed the no longer needed "serial_input" command.
* read_line(): Also support 0x7f as backspace code. That's what xterm sends.

We need to guarantee that when cancel returns that the callback won't be called
anymore. It could happen that the transfer was already in the process of being
finished, so wasn't in the list of pending transfers anymore. Cancel would then
return even though the callback wasn't called yet. This could lead to a callback
being called after a driver was already unloaded (even after it cleaned up the
pipes it used).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33239 a95241bf-73f2-0310-859d-f6bbb57e9c96

Do not free the descriptor chains and transfer queue head directly when
finishing transfers. The host controller might still be using some of those
structures. In the (unlikely) case that a freed memory chunk would be
immediately re-used and filled with new values this would lead the controller
to either find invalid values and assert a process error or it could follow
invalid list links leading to host system errors. We have to wait with freeing
until the controller processing the next frame to make sure this cannot happen.
The unlikely case should also have been the cause of bug #2481.

Cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30713 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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.

we properly handle this case (cancel everything and reset the controller) to
avoid flooding the system with interrupts.

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.

* Fix some bugs introduced by myself ;)
* Removed IOC bit on last TD. To find out whether the TD removed is the
last one of a transfer it simply iterate through every transfer submitted. Not the best
solution, but should be ok for now. Improvements will be made when there will be some driver to test it with.
* Clean up


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22545 a95241bf-73f2-0310-859d-f6bbb57e9c96

Change the way UHCI does things. Restructured processing of transfers in the finisher thread:
* Transfer removal is now done only from the finisher
* Processing is only done after the transfer has been removed from the list
* Canceling transfers only sets a flag so the finisher can remove the transfer
* The callback at cancel is done synchronously though

This fixes quite a few race conditions where transfers were processed while they where already removed. It could happen before that callbacks would have been called twice or freed descriptors/callback buffers were accessed.

The max packet size is now set to 64 bytes which is the maximum size allowed. Transfers that caused babble errors before should now work.

* Don't inherit Device and Interface from pipes anymore. The device has a default pipe member 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 ;-)

* Moved convenience endpoint requests from ControlPipe to Pipe

With this change, bulk transfers are fairly stable now. See here for evidence: http://haiku.mlotz.ch/haiku-usb01.png ;).

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.

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.

UHCI USB: add MSI support

* similar to OHCI support by mmlr.
* interrupt handler is removed on destruction.

Fixed UHCI for x86_64.

* Added arch_debug_blue_screen_try_getchar() and arch_debug_serial_try_getchar()
which don't wait for a character, but return -1 when no character is
available ATM. Implemented correctly for x86 only.
* Changed the semantics of the debugger_module_info::debugger_getchar() hook.
It is supposed to return immediately now.
* Adjusted usb_keyboard accordingly. Hacked UHCI's debug_process_transfer() to
achieve that. It does now start, check, or cancel a transfer. Split
UHCI::ProcessDebugTransfer() into StartDebugTransfer(), and
CheckDebugTransfer() accordingly, and also added a CancelDebugTransfer().
The latter seems to have issues. Michael, please have a look. I have no clue
what I'm doing. :-)
* Adjusted kgetc() to poll all possible inputs using the new
functions/semantics. This allows to use any input (USB, PS/2, serial) in KDL.
* Removed the no longer needed "serial_input" command.
* read_line(): Also support 0x7f as backspace code. That's what xterm sends.

Some more constness.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36250 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

We need to guarantee that when cancel returns that the callback won't be called
anymore. It could happen that the transfer was already in the process of being
finished, so wasn't in the list of pending transfers anymore. Cancel would then
return even though the callback wasn't called yet. This could lead to a callback
being called after a driver was already unloaded (even after it cleaned up the
pipes it used).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33239 a95241bf-73f2-0310-859d-f6bbb57e9c96

Do not free the descriptor chains and transfer queue head directly when
finishing transfers. The host controller might still be using some of those
structures. In the (unlikely) case that a freed memory chunk would be
immediately re-used and filled with new values this would lead the controller
to either find invalid values and assert a process error or it could follow
invalid list links leading to host system errors. We have to wait with freeing
until the controller processing the next frame to make sure this cannot happen.
The unlikely case should also have been the cause of bug #2481.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30714 a95241bf-73f2-0310-859d-f6bbb57e9c96

Cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30713 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29291 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

* When encountering an unrecoverable error at least turn off interrupts until
we properly handle this case (cancel everything and reset the controller) to
avoid flooding the system with interrupts.
* Also only check for enabled interrupts to not steal potentially shared
interrupts.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25823 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Small clean up


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22985 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

* Fix some bugs introduced by myself ;)
* Removed IOC bit on last TD. To find out whether the TD removed is the
last one of a transfer it simply iterate through every transfer submitted. Not the best
solution, but should be ok for now. Improvements will be made when there will be some driver to test it with.
* Clean up


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22545 a95241bf-73f2-0310-859d-f6bbb57e9c96

Change the way UHCI does things. Restructured processing of transfers in the finisher thread:
* Transfer removal is now done only from the finisher
* Processing is only done after the transfer has been removed from the list
* Canceling transfers only sets a flag so the finisher can remove the transfer
* The callback at cancel is done synchronously though

This fixes quite a few race conditions where transfers were processed while they where already removed. It could happen before that callbacks would have been called twice or freed descriptors/callback buffers were accessed.

Patches by Salvatore Benedetto to fix changes made by me and also the underlaying problem that caused high CPU usage in the isochronous finisher thread. Also includes patches to support isochronous support through USBKit / usb_raw. Thanks!

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21636 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixing bug #1284.

* Rearranged isochronous finishing to happen from within the finisher thread
* Removed the separate isochronous finishing thread

Since the finisher thread blocks when no transfers are complete this should bring down CPU load.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21057 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed design flaw in the UHCI fragment implementation and a memory leak both introduced in the last commit.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20418 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented fragmented USB transfers. The transfer length will max out at a certain point to not overflow the allocator. The fragmented transfers are resubmitted until all fragments are sent / received.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20416 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Reworked transfer queuing so that each transfer is grouped with it's own queue head
* Fixed max packet size under bandwidth reclamation
* Increased the thread priority of the finisher thread so that USB input devices should be more responsible under load
* Added a comment to clarify the queue concept

The queue management should now be less complex and less error prone.
The max packet size is now set to 64 bytes which is the maximum size allowed. Transfers that caused babble errors before should now work.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19738 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented compatibility workaround for BeOS to be able to write user memory from the kernel finisher thread

This fixes crashing of the USB Mass Storage driver under R5. It is fully working there now.
I hope to be able to do this more cleanly under Haiku though.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18894 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented usable thread synchronisation for UHCI and EHCI.
* Cleaned interrupt handlers for both busses, too.
* Fixed memory leak of the queue head stray descriptors in EHCI.
* Fixed warnings about assigning NULL to the module flags field.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18857 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

* Adding skeleton EHCI driver. Some parts filled from the specs and the UHCI driver.
* Corrected some errors I found while reading UHCI.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18626 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

* Implemented iovec based data handling in Transfer and UHCI
* Implemented QueueBulkV of the v3 API that uses it

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18540 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

* Fixed data toggle handling. It must be taken after the transfer finished and from the last transmitted transfer descriptor (which in case of a short packet is not neccessarily the last descriptor of the chain)
* Moved convenience endpoint requests from ControlPipe to Pipe

With this change, bulk transfers are fairly stable now. See here for evidence: http://haiku.mlotz.ch/haiku-usb01.png ;). Those are pictures from my Canon Digital Ixus 750 downloaded with Exposure using the PTP plugin. I of course navigated Haiku with my USB Logitech iFeel mouse which works nice since some days.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18510 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

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

* 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

And another forgotten header. Sorry to pollute the logs :-).

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17617 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.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17611 a95241bf-73f2-0310-859d-f6bbb57e9c96

The framelist was allocated in the object which caused the host controller to fail. Also the root hub is now setup after the host controller is started since new devices are created which use transfers to discover their parameters. The controller should now be correctly initialized and stay up.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17610 a95241bf-73f2-0310-859d-f6bbb57e9c96

Some major reworking. Re-enable the old way of building up the framelist pointers. MAke some parts more verbose for testing. Fix the stray td to actually something useful.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13993 a95241bf-73f2-0310-859d-f6bbb57e9c96

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.
