2015-11-05libpayload: xhci: Add delay to get reset working more reliablyRajmohan Mani
Existing Intel xHCI controllers require a delay of 1 ms, after setting the CMD_RESET bit in command register, before accessing any HC registers. This allows the HC to complete the reset operation and be ready for HC register access. Without this delay, the subsequent HC register access, may result in a system hang, very rarely. Verified CherryView / Braswell platforms go through over 1000 warm reboot cycles (which was not possible without this patch), without any xHCI reset hang in depthcharge.

The xhci_rh_port_status_changed() function tries to always clear all port status bits, even though most of them don't interest us. This is generally a smart thing to do since not clearing a status bit may cause the controller to not generate any more Port Status Change Events. However, the bitmask we currently use doesn't cover bit 23 (Port Config Error Change) and instead covers bit 16 (Port Link State Write Strobe) which is not really related to this and not a W1C bit.

I kinda seem to have slipped them into the backport of Nico's original XHCI patch (crosreview.com/168097) instead of making a new change, which was not very clever and caused them to be forgotten in the later upstreaming wave.

2015-07-18libpayload: usb: xhci: Prevent address reuseJulius Werner
We have been trying to avoid reassigning previously used USB addresses to different devices since CL:197420, because some devices seem to take issue with that. Unfortunately, that patch doesn't affect XHCI: those controllers insist on chosing addresses on their own. The only way to prevent them from reusing a previously assigned address is to not disable that slot at all. This patch implements address reuse avoidance on XHCI by not disabling slots when a device is detatched (which may occur both on physical detachment or if we simply couldn't find a driver for that device). Instead, we just release as many resources as we can for detached devices (by dropping all endpoint contexts) and defer the final cleanup until the point where the controller actually runs out of resources (a point that we probably don't often reach in most firmware scenarios).

2015-06-03libpayload: usb: Support MTK xHCI host controllerYidi Lin
1. There is a mis-understanding to calculate the value of TD Size in Normal TRB. For MTK's xHCI controller it defines a number of packets that remain to be transferred for a TD after processing all Max packets in all previous TRBs, that means don't include the current TRB's. 2. To minimize the scheduling effort for synchronous endpoints in xHC, the MTK architecture defines some extra SW scheduling parameters for HW. According to these parameters provided by SW, the xHC can easily decide whether a synchronous endpoint should be scheduled in a specific uFrame. The extra SW scheduling parameters are put into reserved DWs in Slot and Endpoint Context. But in coreboot synchronous transfer can be ignored, so only two fields are set to a default value 1 to support bulk and interrupt transfers, and others are set to zero. 3. For control transfer, it is better to read back doorbell register or add a memory barrier after ringing the doorbell to flush posted write. Otherwise the first command will be aborted on MTK's xHCI controller. 4. Before send commands to a port, the Port Power in PORTSC register should be set to 1 on MTK's xHCI so a hook function of enable_port in generic_hub_ops_t struct is provided.

As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

In this case the usb_scan_pci_bus routine gets into an infinite recursive loop which ends only when the heap or stack is exhausted. This patch verifies that the PCI bridge is enabled by verifying that it is enabled for either memory or I/O operations. When enabled, the secondary bus is scanned.

Under these conditions, the execution of the Event Data TRB is necessary to complete the TD, otherwise it does not occur until the next time the Stream is scheduled. This could lead to the lock up.

I always thought the support for multiple logical SCSI units in the USB mass storage class was a dead feature. Turns out that it's actually used by SD card readers that provide multiple slots (e.g. one regular sized and one micro-SD). Implementing perfect support for that would require a major redesign of the whole MSC stack, since the one device -> one disk assumption is deeply embedded in our data structures. Instead, this patch implements a poor man's LUN support that will just cycle through all available LUNs (in multiple calls to usb_msc_poll()) until it finds a connected device. This should be reasonable enough to allow these card readers to be usable while only requiring superficial changes. Also removes the unused 'protocol' attribute of usb_msc_inst_t.

So I was debugging this faulty USB SD card reader that would just fail it's REQUEST SENSE response for some reason (sending the CSW immediately without the data), cursing those damn device vendors for building non-compliant crap like I always do... when I noticed that we do not actually set the Allocation Length field in our REQUEST SENSE command block at all! We set a length in the CBW, but the SCSI command still has its own length field and the SCSI spec specifically says that the device has to return the exact amount of bytes listed there (even if it's 0). I don't know what's more suprising: that we had such a blatant bug in this stack for so long, or that this card reader is really the first device to actually be spec compliant in that regard. This patch fixes the bug and changes the command block structures to be a little easier to read (why that field was called 'lun' before is beyond me... LUN is a transport level thing and should never appear in the command block at all, for any command). It also fixes a memcpy() in wrap_cbw() to avoid a read buffer overflow that might expose stack frame data to the device.

2014-12-22libpayload: usb: Try to avoid reusing device addressesJulius Werner
We recently changed the USB stack to detach devices aggressively that we don't intend to use. This alone is not really a problem, but it exarcerbates the fact that our device detachment itself is not very good. We destroy any local info about the device, but we don't properly disable the offending port. The device keeps thinking that it's active, and if we later try to reuse that device address for another device things become confused. The real fix would be to properly disable all ports that we don't intend to use. Unfortunately, this isn't really possible in our current device/hub polymorphism structure, and I don't want to hack a new disable_port() callback into usbdev_t that really doesn't belong there. We will only be able to fix this cleanly after we ported all root hubs to the generic_hub interface. Until then, an easy workaround is to just avoid reusing addresses as long as possible. This is firmware, so the chance that we'll ever run through 127 devices is really small in practice. Even if we ever fix the underlying issue, it's probably a smart precaution to keep.

We've recently fixed a problem where an external hard drive would choke due to one too many CLEAR_FEATURE(HALT) commands in the XHCI stack with "libpayload: usb: xhci: Fix STALL endpoint handling". Clearing stall conditions from within the transfer function is wrong in general... this is really something that is host controller agnostic and should be left to the higher-level driver to decide. The mass storage driver (the only one that should really encounter stalls right now) already contains the proper amount of clear_stall() calls... any more than that is redundant and as we found out potentially dangerous. This patch removes automatic clear stalls from UHCI and OHCI drivers as well to make things consistent between host controllers. BUG=chromium:192866 TEST=None.

This patch adds the 10ms TRSTRCY delay between a reset and the following Set Address command that is required by the USB 2.0 specification to the EHCI root hub driver. The generic_hub driver that's used for XHCI and external hubs already included this delay. This is such a glaring violation of the spec that I'm really amazed how many USB 2.0 devices we tested before seemed perfectly fine with responding to a Set Address within 2 microframes of the reset... It also increases the port reset hold delay by one millisecond to avoid an ugly race condition on Tegra SoCs: they decided to time the 50ms themselves instead of relying on the CPU to do it (fair enough), and to automatically transition Port Reset to 0 and Port Enable to 1 after that (bad idea). If the CPU's read-modify-write to clear Port Reset races exactly with the host controller setting Port Enable, we may end up clearing the bit again and going into the companion controller handoff path later on. The added millisecond shouldn't cause any problems for other host controllers and is not a big deal compared to other delays in this code path.

2014-09-04libpayload: usb: Refactor USB enumeration to fix SuperSpeed devicesJulius Werner
This patch represents a major overhaul of the USB enumeration code in order to make it cleaner and much more robust to weird or malicious devices. The main improvement is that it correctly parses the USB descriptors even if there are unknown descriptors interspersed within, which is perfectly legal and in particular present on all SuperSpeed devices (due to the SuperSpeed Endpoint Companion Descriptor). In addition, it gets rid of the really whacky and special cased get_descriptor() function, which would read every descriptor twice whether it made sense or not. The new code makes the callers allocate descriptor memory and only read stuff twice when it's really necessary (i.e. the device and configuration descriptors). Finally, it also moves some more responsibilities into the controller-specific set_address() function in order to make sure things are initialized at the same stage for all controllers. In the new model it initializes the device entry (which zeroes the endpoint array), sets up endpoint 0 (including MPS), sets the device address and finally returns the whole usbdev_t structure with that address correctly set. Note that this should make SuperSpeed devices work, but SuperSpeed hubs are a wholly different story and would require a custom hub driver (since the hub descriptor and port status formats are different for USB 3.0 ports, and the whole issue about the same hub showing up as two different devices on two different ports might present additional challenges). The stack currently just issues a warning and refuses to initialize this part of the hub, which means that 3.0 devices connected through a 3.0 hub may not work correctly.

It will then process the leftover TRBs from the old TD the next time a transfer is issued. (cf. XHCI 4.6.9) We fix this by changing the existing xhci_reset_endpoint() calls in transfer functions to not only trigger on Halted (2) and Error (4), but also on Stopped (3). That function will not actually issue a Reset Endpoint command in this case, but it will nuke the whole transfer ring and issue a Set TR Dequeue Pointer command, which is sufficient (though slightly overkill) to solve our problem.

2014-08-18libpayload: usbmsc: Remove DETACHED state from MSC device structureJulius Werner
The USB MSC device structure contains a "ready" state that can be either "ready", "not ready" or "detached". The last one can only be assigned when the device is completely unresponsive and gets forcefully logically detached via usb_detach_device(). This call (at least in the current version) also calls all destructors and frees the complete usbdev_t structure (including the MSC specific part), which unfortunately makes storing the "detached" state in that very structure a little pointless. This patch reduces the "ready" value to a simple boolean and makes sure that all detachment cases immediately return from the MSC driver, carefully avoiding any use-after-free opportunities.

2014-08-14libpayload: xhci: Make XHCI stack usable on ARMJulius Werner
This patch updates the libpayload XHCI stack to run on ARM CPUs (tested with the DWC3 controller on an Exynos5420). Firstly, it adds support for 64-byte Slot/Endpoint Context sizes. Since the existing context handling code represented the whole device context as a C struct (whose size has to be known at compile time), it was necessary to refactor the input and device context structures to consist of pointers to the actual contexts instead. Secondly, it moves all data structures that the xHC accesses through DMA to cache-coherent memory. With a similar rationale as in the ARM patches for EHCI, using explicit cache maintenance functions to correctly handle the actual transfer buffers in all cases is presumably impossible. Instead this patch also chooses to create a DMA bounce buffer in the XHCI stack where transfer buffers which are not already cache-coherent will be copied to/from.

This patch makes the EHCI driver work on ARM platforms which usually do not support automatic cache snooping.

It turns out that my previous commit to make the EHCI stack cache aware on ARM devices wasn't quite correct, and the problem is actually much trickier than I thought. After having some fun with more weird transfer problems that appear/disappear based on stack alignment, this is my current worst-case threat model that any cache managing implementation would need to handle correctly: Some upper layer calls ehci_bulk() with a transfer buffer on its stack. Due to stack alignment, it happens to start just at the top of a cache line, so up to 64 - 4 bytes of ehci_bulk's stack will share that line. ehci_bulk() calls dcache_clean() and initializes the USB transfer. Between that point and the call to dcache_invalidate() at the end of ehci_bulk(), any access to the stack variables in that cache line (even a speculative prefetch) will refetch the line into the cache. Afterwards any other access to a random memory location that just happens to get aliased to the same cache line may evict it again, causing the processor to write out stale data to the transfer buffer and possibly overwrite data that has already been received over USB. In short, any dcache_clean/dcache_invalidate-based implementation that preserves correctness while allowing any arbitrary (non cache-aligned) memory location as a transfer buffer is presumed to be impossible. Instead, this patch causes all transfer data to be copied to/from a cache-coherent bounce buffer. It will still transfer directly if the supplied buffer is already cache-coherent, which can be used by callers to optimize their transfers (and is true by default on x86).

2014-08-12libpayload: Make USB transfer functions return amount of bytesJulius Werner
The USB bulk and control transfer functions in libpayload currently always return 0 for success and 1 for all errors. This is sufficient for current use cases (essentially just mass storage), but other classes (like certain Ethernet adapters) need to be able to tell if a transfer reached the intended amount of bytes, or if it fell short. This patch slightly changes that USB API to return -1 on errors, and the amount of transferred bytes on successes. All drivers in the current libpayload mainline are modified to conform to the new error detection model. Any third party users of this API will need to adapt their if (...<controller>->bulk/control(...)) checks to if (...<controller>->bulk/control(...) < 0) as well. The host controller drivers for OHCI and EHCI correctly implement the new behavior. UHCI and the XHCI stub just comply with the new API by returning 0 or -1, but do not actually count the returned bytes.

2014-08-11libpayload: xhci: Use Event Data TRBs for transfer event generationJulius Werner
The current XHCI code only sets IOC on the last TRB of a TD, and doesn't set ISP anywhere. On my Synopsys DesignWare3 controller, this won't generate an event at all when we have a short transfer that is not on the last TRB of a TD, resulting in event ring desync and everyone having a bad time. However, just setting ISP on other TRBs doesn't really make for a nice solution: we then need to do ugly special casing to fish out the spurious second transfer event you get for short packets, and we still need a way to figure out how many bytes were transferred. Since the Short Packet transfer event only reports untransferred bytes for the current TRB, we would have to manually walk the rest of the unprocessed TRB chain and add up the bytes. Check out U-Boot and the Linux kernel to see how complicated this looks in practice. Now what if we had a way to just tell the HC "I want an event at exactly *this* point in the TD, I want it to have the right completion code for the whole TD, and to contain the exact number of bytes written"? Enter the Event Data TRB: this little gizmo really does pretty much exactly what any sane XHCI driver would want, and I have no idea why it isn't used more often. It solves both the short packet event generation and counting the transferred bytes without requiring any special magic in software.

2013-11-25libpayload: usb mass storage detect empty mediaAaron Durbin
There is currently a hard-coded 30 sec delay in the mass storage driver while waiting for each device to become ready. However, mass storage card readers that are empty return an error code on the TEST UNIT READY command. A REQUEST SENSE command then needs to be issued and interrogate the data to determine if no media is present. If no media determination is found to be true the USB device is no longer considered a candidate to be a disk. This code does lead to the fact that the media card reader needs to be populated at enumeration time. I suspect this is not an issue as it appears the storage stack in libpayload can't handle removable media coming online later. Booted recovery and dev modes. Noted that removable mass storage devices with no media were ignored without any boot delay.

2013-11-25libpayload (EHCI): correctly align PORTSCStefan Reinauer
Two structures in the USB EHCI stack were pointing to hardware but not marked attribute((packed)) hence leaving it to GCC to correctly align the data structures. Next, the number of reserved bytes in hc_op_t was wrong (but implicitly aligned to the correct values on x86) It seems this worked fine on x86, but on ARM it was doing the wrong thing.

2013-09-30libpayload: Switch xHCI shared ports back to EHCI on shutdownNico Huber
On Intel's Panther Point the xHCI ports are shared with an EHCI controller. Our xHCI driver switches them to xHCI, naturally. But we forgot to switch them back on shutdown, which left them unusable by a non-xHCI aware operating system.

2013-06-13libpayload: Fill gaps in the xHCI driverNico Huber
Well, it turned out to be more as some gaps ;) but we finally have xHCI running. It's well tested against a QM77 Ivy Bridge board. We have no SuperSpeed support (yet). On Ivy Bridge, SuperSpeed is not advertised and USB 3 devices will just work at HighSpeed. There are still some bit fields in xhci_private.h, so this might need little more work to run on ARM.

2013-06-13libpayload: Add a generic driver for usb hubsNico Huber
The current drivers for external usb hubs and root hubs all follow the same pattern. Before adding another one with 90% of the same code, extract the common parts and rewrite them with a simple interface. This also adds debouncing of new attachments. Current drivers just waited 100ms before they reset the device. However, we should check if the device becomes disconnected and reconnected during this period. Porting of the current hub drivers will take place in separate commits (when I have time to test the older HCIs).

2013-06-13libpayload: Redirect USB slave init through controller driverPatrick Georgi
xHCI requires special treatment of set_address since it determines the device number itself (instead of the driver, as with the other controllers). The controller also wants to validate a chosen device configuration and we need to setup additional structures for the device and the endpoints. Therefore, we add three functions to the hci_t structure, namely: set_address() finish_device_config() destroy_device() Current implementation for the Set Address request moved into generic_set_address() which is set_address() for the UHCI, OCHI and EHCI drivers. The latter two are only provided as hooks for the xHCI driver. The Set Configuration request is moved after endpoint enumeration. For all other controller drivers nothing changes, as there is no other device communication between the lines where the set_configuration() call moved.

2013-04-08libpayload: Handle multifunction bridge devices better.Gabe Black
This change modifies the code in libpayload that scans the PCI hierarchy for USB controllers. Previously, if a devices primary function (function 0) was a bridge, then none of the other functions, if any, would be looked at. If one of the other functions was a bridge, that wouldn't be handled either. The new version looks at each function that's present no matter what, and if it discovers that it's a bridge it scans the other side.
