platform/surface: aggregator: Fix kernel-doc references
Both, ssh_rtl_rx_start() and ssh_rtl_tx_start() functions, do not exist and have been consolidated into ssh_rtl_start(). Nevertheless, kernel-doc references the former functions. Replace those references with references to ssh_rtl_start().

platform/surface: aggregator_cdev: Add comments regarding unchecked allocation size
CI static analysis complains about the allocation size in payload and
response buffers being unchecked. In general, these allocations should
be safe as the user-input is u16 and thus limited to U16_MAX, which is
only slightly larger than the theoretical maximum imposed by the
underlying SSH protocol.
All bounds on these values required by the underlying protocol are
enforced in ssam_request_sync() (or rather the functions called by it),
thus bounds here are only relevant for allocation.
Add comments explaining that this should be safe.

platform/surface: Add Surface ACPI Notify driver
The Surface ACPI Notify (SAN) device provides an ACPI interface to the Surface Aggregator EC, specifically the Surface Serial Hub interface. This interface allows EC requests to be made from ACPI code and can convert a subset of EC events back to ACPI notifications. Specifically, this interface provides a GenericSerialBus operation region ACPI code can execute a request by writing the request command data and payload to this operation region and reading back the corresponding response via a write-then-read operation. Furthermore, this interface provides a _DSM method to be called when certain events from the EC have been received, essentially turning them into ACPI notifications. The driver provided in this commit essentially takes care of translating the request data written to the operation region, executing the request, waiting for it to finish, and finally writing and translating back the response (if the request has one). Furthermore, this driver takes care of enabling the events handled via ACPI _DSM calls. Lastly, this driver also exposes an interface providing discrete GPU (dGPU) power-on notifications on the Surface Book 2, which are also received via the operation region interface (but not handled by the SAN driver directly), making them accessible to other drivers (such as a dGPU hot-plug driver that may be added later on). On 5th and 6th generation Surface devices (Surface Pro 5/2017, Pro 6, Book 2, Laptop 1 and 2), the SAN interface provides full battery and thermal subsystem access, as well as other EC based functionality. On those models, battery and thermal sensor devices are implemented as standard ACPI devices of that type, however, forward ACPI calls to the corresponding Surface Aggregator EC request via the SAN interface and receive corresponding notifications (e.g. battery information change) from it. This interface is therefore required to provide said functionality on those devices.

platform/surface: Add Surface Aggregator user-space interface
Add a misc-device providing user-space access to the Surface Aggregator EC, mainly intended for debugging, testing, and reverse-engineering. This interface gives user-space applications the ability to send requests to the EC and receive the corresponding responses. The device-file is managed by a pseudo platform-device and corresponding driver to avoid dependence on the dedicated bus, allowing it to be loaded in a minimal configuration. A python library and scripts to access this device can be found at [1].

platform/surface: aggregator: Add dedicated bus and device type
The Surface Aggregator EC provides varying functionality, depending on the Surface device. To manage this functionality, we use dedicated client devices for each subsystem or virtual device of the EC. While some of these clients are described as standard devices in ACPI and the corresponding client drivers can be implemented as platform drivers in the kernel (making use of the controller API already present), many devices, especially on newer Surface models, cannot be found there. To simplify management of these devices, we introduce a new bus and client device type for the Surface Aggregator subsystem. The new device type takes care of managing the controller reference, essentially guaranteeing its validity for as long as the client device exists, thus alleviating the need to manually establish device links for that purpose in the client driver (as has to be done with the platform devices).

platform/surface: aggregator: Add error injection capabilities
This commit adds error injection hooks to the Surface Serial Hub communication protocol implementation, to: - simulate simple serial transmission errors, - drop packets, requests, and responses, simulating communication failures and potentially trigger retransmission timeouts, as well as - inject invalid data into submitted and received packets. Together with the trace points introduced in the previous commit, these facilities are intended to aid in testing, validation, and debugging of the Surface Aggregator communication layer.

platform/surface: aggregator: Add event item allocation caching
Event items are used for completing Surface Aggregator EC events, i.e. placing event command data and payload on a workqueue for later processing to avoid doing said processing directly on the receiver thread. This means that event items are allocated for each incoming event, regardless of that event being transmitted via sequenced or unsequenced packets. On the Surface Book 3 and Surface Laptop 3, touchpad HID input events (unsequenced), can constitute a larger amount of traffic, and therefore allocation of event items. This warrants caching event items to reduce memory fragmentation. The size of the cached objects is specifically tuned to accommodate keyboard and touchpad input events and their payloads on those devices. As a result, this effectively also covers most other event types. In case of a larger event payload, event item allocation will fall back to kzalloc().

platform/surface: aggregator: Add control packet allocation caching
Surface Serial Hub communication is, in its core, packet based. Each sequenced packet requires to be acknowledged, via an ACK-type control packet. In case invalid data has been received by the driver, a NAK-type (not-acknowledge/negative acknowledge) control packet is sent, triggering retransmission. Control packets are therefore a core communication primitive and used frequently enough (with every sequenced packet transmission sent by the embedded controller, including events and request responses) that it may warrant caching their allocations to reduce possible memory fragmentation.

platform/surface: Add Surface Aggregator subsystem
Add Surface System Aggregator Module core and Surface Serial Hub driver, required for the embedded controller found on Microsoft Surface devices. The Surface System Aggregator Module (SSAM, SAM or Surface Aggregator) is an embedded controller (EC) found on 4th and later generation Microsoft Surface devices, with the exception of the Surface Go series. This EC provides various functionality, depending on the device in question. This can include battery status and thermal reporting (5th and later generations), but also HID keyboard (6th+) and touchpad input (7th+) on Surface Laptop and Surface Book 3 series devices. This patch provides the basic necessities for communication with the SAM EC on 5th and later generation devices. On these devices, the EC provides an interface that acts as serial device, called the Surface Serial Hub (SSH). 4th generation devices, on which the EC interface is provided via an HID-over-I2C device, are not supported by this patch. Specifically, this patch adds a driver for the SSH device (device HID MSHW0084 in ACPI), as well as a controller structure and associated API. This represents the functional core of the Surface Aggregator kernel subsystem, introduced with this patch, and will be expanded upon in subsequent commits. The SSH driver acts as the main attachment point for this subsystem and sets-up and manages the controller structure. The controller in turn provides a basic communication interface, allowing to send requests from host to EC and receiving the corresponding responses, as well as managing and receiving events, sent from EC to host. It is structured into multiple layers, with the top layer presenting the API used by other kernel drivers and the lower layers modeled after the serial protocol used for communication. Said other drivers are then responsible for providing the (Surface model specific) functionality accessible through the EC (e.g. battery status reporting, thermal information, ...) via said controller structure and API, and will be added in future commits.

platform/x86: touchscreen_dmi: Add swap-x-y quirk for Goodix touchscreen on Estar Beauty HD tablet
The Estar Beauty HD (MID 7316R) tablet uses a Goodix touchscreen, with the X and Y coordinates swapped compared to the LCD panel. Add a touchscreen_dmi entry for this adding a "touchscreen-swapped-x-y" device-property to the i2c-client instantiated for this device before the driver binds. This is the first entry of a Goodix touchscreen to touchscreen_dmi.c, so far DMI quirks for Goodix touchscreen's have been added directly to drivers/input/touchscreen/goodix.c. Currently there are 3 DMI tables in goodix.c: 1. rotated_screen[] for devices where the touchscreen is rotated 180 degrees vs the LCD panel 2. inverted_x_screen[] for devices where the X axis is inverted 3. nine_bytes_report[] for devices which use a non standard touch report size Arguably only 3. really needs to be inside the driver and the other 2 cases are better handled through the generic touchscreen DMI quirk mechanism from touchscreen_dmi.c, which allows adding device-props to any i2c-client. Esp. now that goodix.c is using the generic touchscreen_properties code. Alternative to the approach from this patch we could add a 4th dmi_system_id table for devices with swapped-x-y axis to goodix.c, but that seems undesirable.

platform/x86: i2c-multi-instantiate: Don't create platform device for INT3515 ACPI nodes
There are several reports about the tps6598x causing
interrupt flood on boards with the INT3515 ACPI node, which
then causes instability. There appears to be several
problems with the interrupt. One problem is that the
I2CSerialBus resources do not always map to the Interrupt
resource with the same index, but that is not the only
problem. We have not been able to come up with a solution
for all the issues, and because of that disabling the device
for now.
The PD controller on these platforms is autonomous, and the
purpose for the driver is primarily to supply status to the
userspace, so this will not affect any functionality.

drm/amd/display: avoid uninitialized variable warning
clang (quite rightly) complains fairly loudly about the newly added
mpc1_get_mpc_out_mux() function returning an uninitialized value if the
'opp_id' checks don't pass.
This may not happen in practice, but the code really shouldn't return
garbage if the sanity checks don't pass.
So just initialize 'val' to zero to avoid the issue.

perf tools changes for v5.11, 2nd batch:
- Refactor 'perf stat' per CPU/socket/die/thread aggregation fixing use
cases in ARM machines.
- Fix memory leak when synthesizing SDT probes in 'perf probe'.
- Update kernel header copies related to KVM, epol_pwait. msr-index and
powerpc and s390 syscall tables.
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
