commit 58b2939b4d5a030eaec469d29812ab8477ee7e76 upstream.
When the xHCI driver is not available, actively switch the ports to EHCI
mode since some BIOSes leave them in xHCI mode where they would
otherwise appear dead. This was discovered on a Dell Optiplex 7010,
but it's possible other systems could be affected.
This should be backported to kernels as old as 3.0, that contain the
commit 69e848c2090aebba5698a1620604c7dccb448684 "Intel xhci: Support

commit 48c3375c5f69b1c2ef3d1051a0009cb9bce0ce24 upstream.
This patch (as1640) fixes a memory leak in xhci-hcd. The urb_priv
data structure isn't always deallocated in the handle_tx_event()
routine for non-control transfers. The patch adds a kfree() call so
that all paths end up freeing the memory properly.

commit f18f8ed2a9adc41c2d9294b85b6af115829d2af1 upstream.
To calculate the TD size for a particular TRB in an isoc TD, we need
know the endpoint's max packet size. Isochronous endpoints also encode
the number of additional service opportunities in their wMaxPacketSize
field. The TD size calculation did not mask off those bits before using
the field. This resulted in incorrect TD size information for
isochronous TRBs when an URB frame buffer crossed a 64KB boundary.
For example:
- an isoc endpoint has 2 additional service opportunites and
a max packet size of 1020 bytes
- a frame transfer buffer contains 3060 bytes
- one frame buffer crosses a 64KB boundary, and must be split into
one 1276 byte TRB, and one 1784 byte TRB.
The TD size is is the number of packets that remain to be transferred
for a TD after processing all the max packet sized packets in the
current TRB and all previous TRBs.
For this TD, the number of packets to be transferred is (3060 / 1020),
or 3. The first TRB contains 1276 bytes, which means it contains one
full packet, and a 256 byte remainder. After processing all the max
packet-sized packets in the first TRB, the host will have 2 packets left
to transfer.
The old code would calculate the TD size for the first TRB as:
total packet count = DIV_ROUND_UP (TD length / endpoint wMaxPacketSize)
total packet count - (first TRB length / endpoint wMaxPacketSize)
The math should have been:
total packet count = DIV_ROUND_UP (3060 / 1020) = 3
3 - (1276 / 1020) = 2
Since the old code didn't mask off the additional service interval bits
from the wMaxPacketSize field, the math ended up as
total packet count = DIV_ROUND_UP (3060 / 5116) = 1
1 - (1276 / 5116) = 1
Fix this by masking off the number of additional service opportunities
in the wMaxPacketSize field.
This patch should be backported to stable kernels as old as 3.0, that
contain the commit 4da6e6f247a2601ab9f1e63424e4d944ed4124f3 "xhci 1.0:

commit 760973d2a74b93eb1697981f7448f0e62767cfc4 upstream.
An isochronous TD is comprised of one isochronous TRB chained to zero or
more normal TRBs. Only the isoc TRB has the TBC and TLBPC fields. The
normal TRBs must set those fields to zeroes. The code was setting the
TBC and TLBPC fields for both isoc and normal TRBs. Fix this.

commit 54a3ac0c9e5b7213daa358ce74d154352657353a upstream.
Usb3.0 device defines function remote wakeup which is only for interface
recipient rather than device recipient. This is different with usb2.0 device's
remote wakeup feature which is defined for device recipient. According usb3.0
spec 9.4.5, the function remote wakeup can be modified by the SetFeature()
requests using the FUNCTION_SUSPEND feature selector. This patch is to use
correct way to disable usb3.0 device's function remote wakeup after suspend
error and resuming.
This should be backported to kernels as old as 3.4, that contain the
commit 623bef9e03a60adc623b09673297ca7a1cdfb367 "USB/xhci: Enable remote

commit 3e619d04159be54b3daa0b7036b0ce9e067f4b5d upstream.
This patch (as1654) fixes a very old bug in ehci-hcd, connected with
scheduling of periodic split transfers. The calculations for
full/low-speed bus usage are all carried out after the correction for
bit-stuffing has been applied, but the values in the max_tt_usecs
array assume it hasn't been. The array should allow for allocation of
up to 90% of the bus capacity, which is 900 us, not 780 us.
The symptom caused by this bug is that any isochronous transfer to a
full-speed device with a maxpacket size larger than about 980 bytes is
always rejected with a -ENOSPC error.

commit ee74290b7853db9d5fd64db70e5c175241c59fba upstream.
This patch (as1652) fixes a long-standing bug in ehci-hcd. The driver
relies on status polls to know when to stop port-resume signalling.
It uses the root-hub status timer to schedule these status polls. But
when the driver for the root hub is resumed, the timer is rescheduled
to go off immediately -- before the port is ready. When this happens
the timer does not get re-enabled, which prevents the port resume from
finishing until some other event occurs.
The symptom is that when a new device is plugged in, it doesn't get
recognized or enumerated until lsusb is run or something else happens.
The solution is to re-enable the root-hub status timer after every
status poll while a port resume is in progress.
This bug hasn't surfaced before now because we never used to try to
suspend the root hub in the middle of a port resume (except by
coincidence).

commit fd5d93a0015ce1a7db881382022b2fcdfdc61760 upstream.
If the requested number of DWs on the ring is larger than
the size of the ring itself, return an error.
In testing with large VM updates, we've seen crashes when we
try and allocate more space on the ring than the total size
of the ring without checking.
This prevents the crash but for large VM updates or bo moves
of very large buffers, we will need to break the transaction
down into multiple batches. I have patches to use IBs for
the next kernel.

commit 9452618e7462181ed9755236803b6719298a13ce upstream.
DMAR support on g4x/gm45 integrated gpus seems to be totally busted.
So don't bother, but instead disable it by default to allow distros to
unconditionally enable DMAR support.
v2: Actually wire up the right quirk entry, spotted by Adam Jackson.
Note that according to intel marketing materials only g45 and gm45
support DMAR/VT-d. So we have reports for all relevant gen4 pci ids by
now. Still, keep all the other gen4 ids in the quirk table in case the
marketing stuff confused me again, which would not be the first time.

commit 318fe782539c4150d1b8e4e6c9dc3a896512cb8a upstream.
The IOMMU may stop processing page translations due to a perceived lack
of credits for writing upstream peripheral page service request (PPR)
or event logs. If the L2B miscellaneous clock gating feature is enabled
the IOMMU does not properly register credits after the log request has

BIOSes are supposed to disable L2B micellaneous clock gating by setting

patch corrects that for those which do not enable this workaround.

commit b88a634a903d9670aa5f2f785aa890628ce0dece upstream.
If cpuidle is disabled, that means that:
per_cpu(acpi_cpuidle_device, pr->id)
is set to NULL as the acpi_processor_power_init ends up failing at
retval = cpuidle_register_driver(&acpi_idle_driver)
(in acpi_processor_power_init) and never sets the per_cpu idle
device. So when acpi_processor_hotplug on CPU online notification
tries to reference said device it crashes:

commit 9f9c9cbb60576a1518d0bf93fb8e499cffccf377 upstream.
The right dmi version is in SMBIOS if it's zero in DMI region
This issue was originally found from an oracle bug.
One customer noticed system UUID doesn't match between dmidecode & uek2.
- HP ProLiant BL460c G6 :
# cat /sys/devices/virtual/dmi/id/product_uuid
00000000-0000-4C48-3031-4D5030333531
# dmidecode | grep -i uuid
UUID: 00000000-0000-484C-3031-4D5030333531
From SMBIOS 2.6 on, spec use little-endian encoding for UUID other than
network byte order.
So we need to get dmi version to distinguish. If version is 0.0, the
real version is taken from the SMBIOS version. This is part of original
kernel comment in code.

As of version 2.6 of the SMBIOS specification, the first 3 fields of the
UUID are supposed to be little-endian encoded.
Also a minor fix to match variable meaning and mute checkpatch.pl

commit afd5e34b2bb34881d3a789e62486814a49b47faa upstream.
scsi_register_driver will register a prep_fn() function, which
in turn migh need to use the sd_cdp_pool for DIF.
Which hasn't been initialised at this point, leading to
a crash. So reshuffle the init_sd() and exit_sd() paths
to have the driver registered last.

commit 0f815a0a700bc10547449bde6c106051a035a1b9 upstream.
This patch (as1644) fixes a race that occurs during startup in
uhci-hcd. If the IRQ line is shared with other devices, it's possible
for the handler routine to be called before the data structures are
fully initialized.
The problem is fixed by adding a check to the IRQ handler routine. If
the initialization hasn't finished yet, the routine will return
immediately.

commit d347e75847c1fb299c97736638f45e6ea39702d4 upstream.
Use non-ordered workqueue for attention button events.
Attention button events on each slot can be handled asynchronously. So
we should use non-ordered workqueue. This patch also removes ordered
workqueue in shpchp as a result.
486b10b9f4 ("PCI: pciehp: Handle push button event asynchronously") made
the same change to pciehp. I split this out from a patch by Yijing Wang
<wangyijing@huawei.com> so we fix one thing at a time and to make the
shpchp history correspond more closely with the pciehp history.

commit c2be6f93b383c873a4f9d521afa49b1b67d06085 upstream.
When we have a hotplug-capable PCIe port with a second hotplug-capable
PCIe port below it, removing the device below the upstream port causes
a deadlock.
The deadlock happens because we use the pciehp_wq workqueue to run
pciehp_power_thread(), which uses pciehp_disable_slot() to remove devices
below the upstream port. When we remove the downstream PCIe port, we call
pciehp_remove(), the pciehp driver's .remove() method. That calls
flush_workqueue(pciehp_wq), which deadlocks because the
pciehp_power_thread() work item is still running.
This patch avoids the deadlock by creating a workqueue for every PCIe port
and removing the single shared workqueue.
Here's the call path that leads to the deadlock:
pciehp_queue_pushbutton_work
queue_work(pciehp_wq) # queue pciehp_power_thread
...
pciehp_power_thread
pciehp_disable_slot
remove_board
pciehp_unconfigure_device
pci_stop_and_remove_bus_device
...
pciehp_remove # pciehp driver .remove method
pciehp_release_ctrl
pcie_cleanup_slot
flush_workqueue(pciehp_wq)
This is fairly urgent because it can be caused by simply unplugging a
Thunderbolt adapter, as reported by Daniel below.

commit 9e16721498b0c3d3ebfa0b503c63d35c0a4c0642 upstream.
Right now using pcie_aspm=force will not enable ASPM if the FADT indicates
ASPM is unsupported. However, the semantics of force should probably allow
for this, especially as they did before 3c076351c4 ("PCI: Rework ASPM
disable code")
This patch just skips the clearing of any ASPM setup that the firmware has
carried out on this bus if pcie_aspm=force is being used.
