+
+commit 44fc95e218a09d7966a9d448941fdb003f6bb69f upstream.
+
+Tablet initially begins communicating at 9600 baud, so this command
+should be used to connect to the device:
+
+ $ inputattach --daemon --baud 9600 --wacom_iv /dev/ttyS0

+
+From: Gustavo A. R. Silva <gustavo@embeddedor.com>
+
+commit df997abeebadaa4824271009e2d2b526a70a11cb upstream.
+
+Add missing break statement in order to prevent the code from falling
+through to case ISCSI_BOOT_TGT_NAME, which is unnecessary.
+
+This bug was found thanks to the ongoing efforts to enable
+-Wimplicit-fallthrough.

+Subject: x86/PCI: Fixup RTIT_BAR of Intel Denverton Trace Hub
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Alexander Shishkin <alexander.shishkin@linux.intel.com>
+
+commit 2e095ce7b6ecce2f3e2ff330527f12056ed1e1a1 upstream.
+
+On Denverton's integration of the Intel(R) Trace Hub (for a reference and
+overview see Documentation/trace/intel_th.rst) the reported size of one of
+its resources (RTIT_BAR) doesn't match its actual size, which leads to
+overlaps with other devices' resources.
+
+In practice, it overlaps with XHCI MMIO space, which results in the xhci
+driver bailing out after seeing its registers as 0xffffffff, and perceived
+disappearance of all USB devices:
+
+ intel_th_pci 0000:00:1f.7: enabling device (0004 -> 0006)
+ xhci_hcd 0000:00:15.0: xHCI host controller not responding, assume dead
+ xhci_hcd 0000:00:15.0: xHC not responding in xhci_irq, assume controller is dead
+ xhci_hcd 0000:00:15.0: HC died; cleaning up
+ usb 1-1: USB disconnect, device number 2
+
+For this reason, we need to resize the RTIT_BAR on Denverton to its actual
+size, which in this case is 4MB. The corresponding erratum is DNV36 at the
+link below:
+
+ DNV36. Processor Host Root Complex May Incorrectly Route Memory
+ Accesses to Intel® Trace Hub
+
+ Problem: The Intel® Trace Hub RTIT_BAR (B0:D31:F7 offset 20h) is
+ reported as a 2KB memory range. Due to this erratum, the
+ processor Host Root Complex will forward addresses from
+ RTIT_BAR to RTIT_BAR + 4MB -1 to Intel® Trace Hub.
+
+ Implication: Devices assigned within the RTIT_BAR to RTIT_BAR + 4MB -1
+ space may not function correctly.
+
+ Workaround: A BIOS code change has been identified and may be
+ implemented as a workaround for this erratum.
+
+ Status: No Fix.
+
+Note that 5118ccd34780 ("intel_th: pci: Add Denverton SOC support") updates
+the Trace Hub driver so it claims the Denverton device, but the resource
+overlap exists regardless of whether that driver is loaded or that commit
+is included.
