2015-08-14libpayload: usb: xhci: Fix list of cleared port change bitsJulius Werner
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.

Before the controller's destroy_device() could interrogate the usbdev_t object usb_detach_device() was freeing and NULLing out the pointer. That results in all callers who needed that object to start accessing random bits of memory. This eventually led into free()ing memory it shouldn't which corrupted the allocator's state.

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.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
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>

2015-04-10serial: Combine Tegra and Rockchip UARTs to generic 8250_mmio32Julius Werner
We have two drivers for a 100%-identical peripheral right now, mostly because we couldn't come up with a good common name for it back when we checked it in. That seems like a pretty silly reason in the long run. Both Tegra and Rockchip SoCs contain UARTs that use the common 8250 register interface (at least for the very basic byte-per-byte transmit and receive parts we care about), memory-mapped with a 32-bit register stride. This patch combines them to a single 8250_mmio32 driver (which also fixes a problem when booting Rockchip without serial enabled, since that driver forgot to check for serial initialization when registering its console drivers). The register accesses are done using readl/writel (as Rockchip did before), since the registers are documented as 32-bit length (with top 24 bits RAZ/WI), although the Tegra SoC doesn't enforce APB accesses to have the full word length. Also fixed checkpatch stuff. A day may come when we can also merge this driver into the (completely different, with more complicated features and #ifdefs) 8250 driver for x86 (which has MMIO support for 8-bit register stride only), both here and in coreboot. But it is not this day. This day I just want to get rid of a 99% identical file without expending too much effort. BUG=None TEST=Booted on Veyron_Pinky and Nyan_Blaze with and without serial enabled, both worked fine (although Veyron has another kernel issue).

2015-03-13libpayload: ipq808x: stale interrupt shall not be cleared unconditionallyYogesh Lal
The serial driver hangs in cases when FIFO has more than single word to be processed. Easiest way to reproduce is to paste a string of greater than 4 characters in cli. Clearing the RXSTALE interrupt without draining all the characters from FIFO leads to the issue as the driver is dependent on msm_boot_uart_dm_read function to reinitialize for next transfer. Logically the driver is organized in such a manner that next transfer never gets initiated till rx_data_read < total_rx_data. Clearing the RXSTALE without consideration of total number of characters (or words) unprocessed makes the msm_boot_uart_dm_read to return on the first if conditional. Thus the driver is stuck forever. A quick fix is to avoid clearing the stale interrupt. Reset is handled whenever a new transfer is initialized in msm_boot_uart_dm_init_rx_transfer.

2014-12-30libpayload: video: Make cursor fixup independent of visibilityJulius Werner
The video console runs a video_console_fixup_cursor() function after every printed character to make sure the cursor is still in the output window and avoid overflows. For some crazy reason, this function does not run when cursor_enabled is false... however, that variable is only about cursor *visibility*, and it's imperative that we still do proper bounds checking for our output even if the cursor itself doesn't get displayed (otherwise we can end up overwriting malloc cookies that cause a panic on the next free() and other fun things like that). In fact, there seems to be no reason at all to even keep track of the cursor visibility state in the generic video console framework (the specific backends already do it, too), so let's remove that code entirely. Also set the default cursor visibilty in the corebootfb backend to 0 since that's consistent with what the other backends do.

2014-12-30libpayload: usbmsc: Implement limited LUN supportJulius Werner
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.

2014-12-30libpayload: usbmsc: Set correct allocation length for REQUEST SENSEJulius Werner
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.

2014-12-22libpayload: console: Allow output drivers to print whole strings at onceJulius Werner
The console output driver framework in libpayload is currently built on the putchar primitive, meaning that every driver's function gets called one character at a time. This becomes an issue when we add drivers that could output multiple characters at a time, but have a high constant overhead per invocation (such as the planned GDB stub, which needs to wrap a special frame around output strings and wait for an acknowledgement from the server). This patch adds a new 'write' function pointer to the console_output_driver structure as an alternative to 'putchar'. Output drivers need to provide at least one of the two ('write' is preferred if available). The CBMEM console driver is ported as a proof of concept (since it's our most performace-critical driver and should in theory benefit the most from less function pointer invocations, although it's probably still negligible compared to the big sprawling mess that is printf()). Even with this fix, the problem remains that printf() was written with the putchar primitive in mind. Even though normal text already contains an optimization to allow multiple characters at a time, almost all formatting directives cause their output (including things like padding whitespace) to be putchar()ed one character at a time. Therefore, this patch reworks parts of the output code (especially number printing) to all but remove that inefficiency (directives still invoke an extra write() call, but at least not one per character). Since I'm touching printf() core code anyway, I also tried to salvage what I could from that weird, broken "return negative on error" code path (not that any of our current output drivers can trigger it anyway). A final consequence of this patch is that the responsibility to prepend line feeds with carriage returns is moved into the output driver implementations. Doing this only makes sense for drivers with explicit cursor position control (i.e. serial or video), and things like the CBMEM console that appears like a normal file to the system really have no business containing carriage returns (we don't want people to accidentally associate us with Windows, now, do we?). BUG=chrome-os-partner:18390 TEST=Made sure video and CBMEM console still look good, tried printf() with as many weird edge-case strings as I could find and compared serial output as well as sprintf() return value.

2014-11-13libpayload: usb: Remove automatic clear_stall() calls from transfersJulius Werner
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. I could borrow the original hard drive from Shawn and compile a Snow to only use the OHCI driver to reproduce/verify this, but alas, I am lazy (and it's really not that important).

This patch combines a few minor fixes and refactoring to the various host controller and root hub drivers to ensure they all do the right thing on a call to usb_exit(). It puts a usb_detach_device(0) call into detach_controller() so that the HCD doesn't need to remember to tear down the root hub itself, and makes sure all root hubs properly detach the subtree of devices connected to their ports first (as generic_hub and by extension XHCI had already been doing). It also fixes up some missing free() calls and replaces most 'ptr = malloc(); if (!ptr) fatal()' idioms with the new x(z)alloc(). BUG=chromium:343415 TEST=Tested EHCI on Big and OHCI, EHCI, and XHCI on Snow. Could not test UHCI (unless anyone volunteers to port coreboot to a ZGB? ;) ), but the changes are really tame.

2014-10-29libpayload: usb: ehci: Honor 10ms reset recovery periodJulius Werner
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. BUG=chrome-os-partner:26749 TEST=Run several dozen reboot loops with The USB Stick of Death (TM) (a blue Patriot XT 13fe:5200 with bcdDevice = 1.00), make sure it always gets detected correctly.

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.

2014-08-31libpayload: xhci: Ensure to reset dequeue pointer on stopped endpointsJulius Werner
This patch fixes a bug in the XHCI stack that occurs when a multi-TRB TD times out before the last TRB is processed. The driver will correctly issue a Stop Endpoint command in that case, but the xHC will still preserve the transfer state and just pick up right after that on the next doorbell ring. 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.
