2012-03-07xhci: fix port statusGerd Hoffmann1-1/+1
Don't signal port status change if the usb device isn't in attached state. Happens with usb-host devices with the pass-through device being plugged out at the host. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-03-07xhci: fix control xfersGerd Hoffmann1-8/+5
Use the new, direct control transfer submission method instead of bypassing the usb core by calling usb_device_handle_control directly. The later fails for async control transfers. This patch gets xhci + usb-host combo going.
2012-03-07usb: add shortcut for control transfersGerd Hoffmann2-0/+60
Add a more direct code path to submit control transfers. Instead of feeding three usb packets (setup, data, ack) to usb_handle_packet and have the do_token_* functions in usb.c poke the control transfer parameters out of it just submit a single packet carrying the actual data with the control xfer parameters filled into USBPacket->parameters.

2012-03-07usb: add pipelining option to usb endpointsGerd Hoffmann2-1/+12
With this patch applied USB drivers can enable pipelining per endpoint. With pipelining enabled the usb core will continue submitting packets even when there are still async transfers in flight instead of passing them on one by one. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-03-07usb: queue can have async packetsGerd Hoffmann1-0/+3
This can happen today in case the ->complete() callback queues up the next packet. Also we'll support pipelining soon, which allows to have multiple packets per queue in flight (aka ASYNC) state. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-03-07usb: add USB_RET_IOERRORHans de Goede4-5/+11
We already have USB_RET_NAK, but that means that a device does not want to send/receive right now. But with host / network redirection we can actually have a transaction fail due to some io error, rather then ie the device just not having any data atm. This patch adds a new error code named USB_RET_IOERROR for this, and uses it were appropriate. Notes: -Currently all usb-controllers handle this the same as NODEV, but that may change in the future, OHCI could indicate a CRC error instead for example. -This patch does not touch hw/usb-musb.c, that is because the code in there handles STALL and NAK specially and has a if status < 0 generic catch all for all other errors Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-03-07usb-ehci: Cleanup itd error handlingHans de Goede1-14/+14
All error statuses except for NAK are handled in a switch case, move the handling of NAK into the same switch case. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-03-07usb-ehci: Fix and simplify nakcnt handlingHans de Goede1-28/+4
The nakcnt code in ehci_execute_complete() marked transactions as finished when a packet completed with a result of USB_RET_NAK, but USB_RET_NAK means that the device cannot receive / send data at that time and that the transaction should be retried later, which is also what the usb-uhci and usb-ohci code does. Note that there already was some special code in place to handle this for interrupt endpoints in the form of doing a return from ehci_execute_complete() when reload == 0, but that for bulk transactions this was not handled correctly (where as for example the usb-ccid device does return USB_RET_NAK for bulk packets). Besides that the code in ehci_execute_complete() decrement nakcnt by 1 on a packet result of USB_RET_NAK, but -since the transaction got marked as finished, nakcnt would never be decremented again -there is no code checking for nakcnt becoming 0 -there is no use in re-trying the transaction within the same usb frame / usb-ehci frame-timer call, since the status of emulated devices won't change as long as the usb-ehci frame-timer is running So we should simply set the nakcnt to 0 when we get a USB_RET_NAK, thus claiming that we've tried reload times (or as many times as possible if reload is 0). Besides the code in ehci_execute_complete() handling USB_RET_NAK there was also code handling it in ehci_state_executing(), which calls ehci_execute_complete(), and then does its own handling on top of the handling in ehci_execute_complete(), this code would decrement nakcnt *again* (if not already 0), or restore the reload value (which was never changed) on success. Since the double decrement was wrong to begin with, and is no longer needed now that we set nakcnt directly to 0 on USB_RET_NAK, and the restore of reload is not needed either, this patch simply removes all nakcnt handling from ehci_state_executing().

2012-03-07usb-ehci: Remove dead nakcnt codeHans de Goede1-20/+0
This patch removes 2 bits of dead nakcnt code: 1) usb_ehci_execute calls ehci_qh_do_overlay which does: nakcnt = reload; and then has a block of code which is conditional on: if (reload && !nakcnt) { which ofcourse is never true now as nakcnt == reload. 2) ehci_state_fetchqh does: nakcnt = reload; but before nakcnt is ever used ehci_state_fetchqh is always followed by a ehci_qh_do_overlay call which also does: nakcnt = reload; So doing this from ehci_state_fetchqh is redundant.

2012-03-07usb-ehci: Fix cerr trackingHans de Goede1-13/+6
cerr should only be decremented on errors which cause XactErr to be set, and when that happens the failing transaction should be retried until cerr reaches 0 and only then should USBSTS_ERRINT be set (and inactive cleared and USBSTS_INT set if requested). Since we don't have any hardware level errors (and in case of redirection the real hardware has already retried), re-trying makes no sense, so immediately set cerr to 0 on errors which set XactErr.

2012-03-07usb-ehci: Any packet completion except for NAK should set the interruptHans de Goede1-1/+1
As clearly stated in the 2.3.2 of the EHCI spec, any time USBERRINT get sets then if the td has its IOC bit set USBINT should be set as well. This means that for any status except for USB_RET_NAK we should set USBINT if the IOC bit is set. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-03-07usb-ehci: Drop cached qhs when the doorbell gets rungHans de Goede1-16/+17
The purpose of the IAAD bit / the doorbell is to make the ehci controller forget about cached qhs, this is mainly used when cancelling transactions, the qh is unlinked from the async schedule and then the doorbell gets rung, once the doorbell is acked by the controller the hcd knows that the qh is no longer in use and that it can do something else with the memory, such as re-use it for a new qh! But we keep our struct representing this qh around for circa 250 ms. This allows for a (mightily large) race window where the following could happen: -hcd submits a qh at address 0xdeadbeef -our ehci code sees the qh, sends a request to a usb-device, gets a result of USB_RET_ASYNC, sets the async_state of the qh to EHCI_ASYNC_INFLIGHT -hcd unlinks the qh at address 0xdeadbeef -hcd rings the doorbell, wait for us to ack it -hcd re-uses the qh at address 0xdeadbeef -our ehci code sees the qh, looks in the async_queue, sees there already is a qh at address 0xdeadbeef there with async_state of EHCI_ASYNC_INFLIGHT, does nothing -the *original* (which the hcd thinks it has cancelled) transaction finishes -our ehci code sees the qh on yet another pass through the async list, looks in the async_queue, sees there already is a qh at address 0xdeadbeef there with async_state of EHCI_ASYNC_COMPLETED, and finished the transaction with the results of the *original* transaction. Not good (tm), this patch fixes this race by removing all qhs which have not been seen during the last cycle through the async list immidiately when the doorbell is rung. Note this patch does not fix any actually observed problem, but upon reading of the EHCI spec it became apparent to me that the above race could happen and the usb-ehci behavior from before this patch is not good.

2012-03-07usb-ehci: always call ehci_queues_rip_unused for period queuesHans de Goede1-0/+1
Before this patch USB 2 devices with interrupt endpoints were not working properly. The problem is that to avoid loops we stop processing as soon as we encounter a queue-head (qh) we've already seen since qhs can be linked in a circular fashion, this is tracked by the seen flag in our qh struct. The resetting of the seen flag is done from ehci_queues_rip_unused which before this patch was only called when executing the statemachine for the async schedule. But packets for interrupt endpoints are part of the periodic schedule! So what would happen is that when there were no ctrl or bulk packets for a USB 2 device with an interrupt endpoint, the async schedule would become non active, then ehci_queues_rip_unused would no longer get called and when processing the qhs for the interrupt endpoints from the periodic schedule their seen bit would still be 1 and they would be skipped.

2012-03-07usb-ehci: split our qh queue into async and periodic queuesHans de Goede1-25/+37

2012-03-07usb-ehci: Never follow table entries with the T-bit setHans de Goede1-6/+4
Before this patch the T-bit was not checked in 2 places, while it should be. Once we properly check the T-bit everywhere we no longer need the weird entry < 0x1000 and entry > 0x1000 checks, so this patch removes them.

This is enabled by default and can be switched off via a device property.

2012-03-05s390: Rework kernel loading: supports elf and newer kernelsChristian Borntraeger1-12/+18
This reworks the image loading on s390. Newer kernels will not always have a 0dd0 (basr 13,0) at address 0x10000. We must not rely on specific code at certain addresses. This check was introduced to warn users that tried to load vmlinux, since ELF loading was not supported. Lets wire that up. If elf loading fails, we assume that this is a standard kernel image and load that via load_image_targphys. This patch also changes all other users of load_image to load_image_targphys to be consistent. (the elf loader registers the kernel as rom).
