The HiDeep IST940E touchscreen controller used on the Lenovo Yoga Book X90F
convertible comes up in HID mode by default.
This works well on the X91F Windows model where the touchscreen is
correctly described in ACPI and ACPI takes care of controlling
the reset GPIO and regulators.
But the X90F ships with Android and the ACPI tables on this model don't
describe the touchscreen. Instead this is hardcoded in the vendor kernel.
The vendor kernel uses the touchscreen in native HiDeep 20 (2.0?) protocol
mode and switches the controller to this mode by writing 0 to reg 0x081e.
Adjusting the i2c-hid code to deal with the reset-gpio and regulators on
this non devicetree (but rather broken ACPI) convertible is somewhat tricky
and the native protocol reports ABS_MT_PRESSURE and ABS_MT_TOUCH_MAJOR
which are not reported in HID mode, so it is preferable to use the native
mode.
Add support to the hideep driver to reset the work-mode to the native
HiDeep protocol to allow using it on the Lenovo Yoga Book X90F.
This is guarded behind a new "hideep,force-native-protocol" boolean
property, to avoid changing behavior on other devices.
For the record: I did test using the i2c-hid driver with some quick hacks
and it does work. The I2C-HID descriptor is available from address 0x0020,
just like on the X91F Windows model.
So far the new "hideep,force-native-protocol" property is only used on
x86/ACPI (non devicetree) devs. IOW it is not used in actual devicetree
files. The devicetree-bindings maintainers have requested properties like
these to not be added to the devicetree-bindings, so the new property is
deliberately not added to the existing devicetree-bindings.

Praveen Kaligineedi says:
====================
gve: Add XDP support for GQI-QPL format
Adding support for XDP DROP, PASS, TX, REDIRECT for GQI QPL format.
Add AF_XDP zero-copy support.
When an XDP program is installed, dedicated TX queues are created to
handle XDP traffic. The user needs to ensure that the number of
configured TX queues is equal to the number of configured RX queues; and
the number of TX/RX queues is less than or equal to half the maximum
number of TX/RX queues.
The XDP traffic from AF_XDP sockets and from other NICs (arriving via
XDP_REDIRECT) will also egress through the dedicated XDP TX queues.
Although these changes support AF_XDP socket in zero-copy mode, there is
still a copy happening within the driver between XSK buffer pool and QPL
bounce buffers in GQI-QPL format.
The following example demonstrates how the XDP packets are mapped to
TX queues:
Example configuration:
Max RX queues : 2N, Max TX queues : 2N
Configured RX queues : N, Configured TX queues : N
TX queue mapping:
TX queues with queue id 0,...,N-1 will handle traffic from the stack.
TX queues with queue id N,...,2N-1 will handle XDP traffic.
For the XDP packets transmitted using XDP_TX action:
<Egress TX queue id> = N + <Ingress RX queue id>
For the XDP packets that arrive from other NICs via XDP_REDIRECT action:
<Egress TX queue id> = N + ( smp_processor_id % N )
For AF_XDP zero-copy mode:
<Egress TX queue id> = N + <AF_XDP TX queue id>
Changes in v2:
- Removed gve_close/gve_open when adding XDP dedicated queues. Instead
we add and register additional TX queues when the XDP program is
installed. If the allocation/registration fails we return error and do
not install the XDP program. Added a new patch to enable adding TX queues
without gve_close/gve_open
- Removed xdp tx spin lock from this patch. It is needed for XDP_REDIRECT
support as both XDP_REDIRECT and XDP_TX traffic share the dedicated XDP
queues. Moved the code to add xdp tx spinlock to the subsequent patch
that adds XDP_REDIRECT support.
- Added netdev_err when the user tries to set rx/tx queues to the values
not supported when XDP is enabled.
- Removed rcu annotation for xdp_prog. We disable the napi prior to
adding/removing the xdp_prog and reenable it after the program has
been installed for all the queues.
- Ring the tx doorbell once for napi instead of every XDP TX packet.
- Added a new helper function for freeing the FIFO buffer
- Unregister xdp rxq for all the queues when the registration
fails during XDP program installation
- Register xsk rxq only when XSK buff pool is enabled
- Removed code accessing internal xsk_buff_pool fields
- Removed sleep driven code when disabling XSK buff pool. Disable
napi and re-enable it after disabling XSK pool.
- Make sure that we clean up dma mappings on XSK pool disable
- Use napi_if_scheduled_mark_missed to avoid unnecessary napi move
to the CPU calling ndo_xsk_wakeup()
Changes in v3:
- Padding bytes are used if the XDP TX packet headers do not
fit at tail of TX FIFO. Taking these padding bytes into account
while checking if enough space is available in TX FIFO.
Changes in v4:
- Turn on the carrier based on the link status synchronously rather
than asynchronously when XDP is installed/uninstalled
- Set the supported flags in net_device.xdp_features

Adding AF_XDP zero-copy support.
Note: Although these changes support AF_XDP socket in zero-copy
mode, there is still a copy happening within the driver between
XSK buffer pool and QPL bounce buffers in GQI-QPL format.
In GQI-QPL queue format, the driver needs to allocate a fixed size
memory, the size specified by vNIC device, for RX/TX and register this
memory as a bounce buffer with the vNIC device when a queue is
created. The number of pages in the bounce buffer is limited and the
pages need to be made available to the vNIC by copying the RX data out
to prevent head-of-line blocking. Therefore, we cannot pass the XSK
buffer pool to the vNIC.
The number of copies on RX path from the bounce buffer to XSK buffer is 2
for AF_XDP copy mode (bounce buffer -> allocated page frag -> XSK buffer)
and 1 for AF_XDP zero-copy mode (bounce buffer -> XSK buffer).
This patch contains the following changes:
1) Enable and disable XSK buffer pool
2) Copy XDP packets from QPL bounce buffers to XSK buffer on rx
3) Copy XDP packets from XSK buffer to QPL bounce buffers and
ring the doorbell as part of XDP TX napi poll
4) ndo_xsk_wakeup callback support
