70fda9e6da usb: gadget: f_tcm: Execute command on write completion
Don't just wait for the data write completion and execute the target
command. We need to verify if the request completed successfully and not
just sending invalid data. The verification is done in the write request
completion routine. Queue the same work of the command to execute the
target_execute_cmd() on data write.

To properly respond to host sending more commands than the number of

should be able to negotiate properly with the host at packet level for
the end of burst.

If the controller can't handle a burst of 16, and high performance isn't
important, the user can use BOT protocol from mass_storage gadget driver
instead.

1aede06981 platform/chrome: cros_ec_typec: Disable tbt on port
Altmodes with cros_ec are either automatically entered by the EC or
entered by the AP if TBT or USB4 are supported on the system. Due to the
security risk of PCIe tunneling, TBT modes should not be auto entered by
the kernel at this time and will require user intervention.

With this change, a userspace program will need to explicitly activate
the thunderbolt mode on the port and partner in order to enter the mode
and the thunderbolt driver will not automatically enter when a partner
is connected.

1ff24d40b3 usb: dwc3: gadget: Fix incorrect UDC state after manual deconfiguration
The UDC state in sysfs (/sys/class/udc/<udc>/state) should accurately
reflect the current state of the USB Device Controller.

Currently, the UDC state is not handled consistently during gadget
disconnection. While the disconnect interrupt path correctly sets the
state to "not-attached", manual deconfiguration leaves the state in
"configured", misrepresenting the actual situation.

This commit ensures consistent UDC state handling by setting the state to
"not-attached" after manual deconfiguration. This accurately reflects the
UDC's state and provides a consistent behavior regardless of the
disconnection method.

ca5d736b74 usbip: Accept arbitrarily long scatter-gather list
Fixes issue where memory will fail to be allocated for larger bulk
transfers, ~1 MB or more. This occurs because userland libraries, such
as libusb, send the entire USB data buffer when SG support is detected.
The assumption is that the driver knows how to properly split the data
up before sending it out.

By hardcoding a limit, bigger transfers that exceed the SG tablesize
limit of 32 will be unable to use SG. This results in an attempt to
allocate contiguous pages which, unsurprisingly, will fail too and
returns an ENOMEM. It looks like other drivers that support SG allow for
any length of SG lists. Accepting any SG size allows the driver to
properly handle large bulk transfer situations.

Tested bulk read and write operations using the following devices:

 - Logitech Webcam Pro 9000 - USB 2.0
 - SanDisk Ultra - USB 3.0
 - Logitech M500s Mouse

 |  No. of data objects = 1   |                       |

 While RMDO consists of:

  * B23..20     Version Major
  * B19..16     Version Minor
  * B15..0      Reserved, shall be set to zero.

As per the PD spec ("8.3.3.16.2.1 PR_Give_Revision State"), a request is
only expected when an explicit contract is established and the port is
in ready state. This AMS is only supported for PD >= 3.0.

6fdc943251 usb: typec: hd3ss3220: support configuring role preference based on fwnode property and typec_operation
The TI HD3SS3220 Type-C controller supports configuring
its role preference when operating as a dual-role port
through the SOURCE_PREF field of the General Control Register.

The previous driver behavior was to set the role preference
based on the dr_set typec_operation.
However, the controller does not support swapping the data role
on an active connection due to its lack of Power Delivery support.

Remove previous dr_set typec_operation, and support setting
the role preference based on the corresponding fwnode property,
as well as the try_role typec_operation.

5d2c32d506 usb: typec: hd3ss3220: support configuring port type
The TI HD3SS3220 Type-C controller supports configuring the port type
it will operate as through the MODE_SELECT field of the General
Control Register.

Configure the port type based on the fwnode property "power-role"
during probe, if present. If the property is absent, leave the
operation mode at the default, which is defined by the PORT pin
of the chip.
Support configuring the port type through the port_type_set
typec_operation as well.

The MODE_SELECT field can only be changed when the controller is in
unattached state, so follow the sequence recommended by the datasheet to:
1. disable termination on CC pins to disable the controller
2. change the mode
3. re-enable termination

This will effectively cause a connected device to disconnect
for the duration of the mode change.

Now that the FSUSB42 USB switches are described, enable support for DP on
the three USB-C ports of the X1E80100 QCP. It supports up to 4 lanes, but
for now we need to limit this to 2 lanes due to limitations in the USB/DP
combo PHY driver. The same limitation also exists on other boards upstream.

increase the buffer to where the warning goes away.

398b7b6cb9 KVM: x86: let it be known that ignore_msrs is a bad idea
When running KVM with ignore_msrs=1 and report_ignored_msrs=0, the user has
no clue that that the guest is being lied to.  This may cause bug reports
such as https://gitlab.com/qemu-project/qemu/-/issues/2571, where enabling
a CPUID bit in QEMU caused Linux guests to try reading MSR_CU_DEF_ERR; and
being lied about the existence of MSR_CU_DEF_ERR caused the guest to assume
other things about the local APIC which were not true:

  Sep 14 12:02:53 kernel: mce: [Firmware Bug]: Your BIOS is not setting up LVT offset 0x2 for deferred error IRQs correctly.
  Sep 14 12:02:53 kernel: unchecked MSR access error: RDMSR from 0x852 at rIP: 0xffffffffb548ffa7 (native_read_msr+0x7/0x40)

Without reported_ignored_msrs=0 at least the host kernel log will contain
enough information to avoid going on a wild goose chase.  But if reports
about individual MSR accesses are being silenced too, at least complain
loudly the first time a VM is started.
