Input: driver for Adafruit Seesaw Gamepad
Adds a driver for a mini gamepad that communicates over i2c, the gamepad
has bidirectional thumb stick input and six buttons.
The gamepad chip utilizes the open framework from Adafruit called 'Seesaw'
to transmit the ADC data for the joystick and digital pin state for the
buttons. I have only implemented the functionality required to receive the
thumb stick and button state.
Steps in reading the gamepad state over i2c:
1. Reset the registers
2. Set the pin mode of the pins specified by the `BUTTON_MASK` to input
`BUTTON_MASK`: A bit-map for the six digital pins internally
connected to the joystick buttons.
3. Enable internal pullup resistors for the `BUTTON_MASK`
4. Bulk set the pin state HIGH for `BUTTON_MASK`
5. Poll the device for button and joystick state done by:
`seesaw_read_data(struct i2c_client *client, struct seesaw_data *data)`

dt-bindings: input: bindings for Adafruit Seesaw Gamepad
Adds bindings for the Adafruit Seesaw Gamepad. The gamepad functions as an i2c device with the default address of 0x50 and has an IRQ pin that can be enabled in the driver to allow for a rising edge trigger on each button press or joystick movement.

xen/gntdev: Fix the abuse of underlying struct page in DMA-buf import
DO NOT access the underlying struct page of an sg table exported by DMA-buf in dmabuf_imp_to_refs(), this is not allowed. Please see drivers/dma-buf/dma-buf.c:mangle_sg_table() for details. Fortunately, here (for special Xen device) we can avoid using pages and calculate gfns directly from dma addresses provided by the sg table.

riscv: select DCACHE_WORD_ACCESS for efficient unaligned access HW
DCACHE_WORD_ACCESS uses the word-at-a-time API for optimised string
comparisons in the vfs layer.
This patch implements support for load_unaligned_zeropad in much the
same way as has been done for arm64.
Here is the test program and step:
$ cat tt.c
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#define ITERATIONS 1000000
#define PATH "123456781234567812345678123456781"
int main(void)
{
unsigned long i;
struct stat buf;
for (i = 0; i < ITERATIONS; i++)
stat(PATH, &buf);
return 0;
}
$ gcc -O2 tt.c
$ touch 123456781234567812345678123456781
$ time ./a.out
Per my test on T-HEAD C910 platforms, the above test performance is
improved by about 7.5%.

riscv: introduce RISCV_EFFICIENT_UNALIGNED_ACCESS
Some riscv implementations such as T-HEAD's C906, C908, C910 and C920 support efficient unaligned access, for performance reason we want to enable HAVE_EFFICIENT_UNALIGNED_ACCESS on these platforms. To avoid performance regressions on other non efficient unaligned access platforms, HAVE_EFFICIENT_UNALIGNED_ACCESS can't be globally selected. To solve this problem, runtime code patching based on the detected speed is a good solution. But that's not easy, it involves lots of work to modify vairous subsystems such as net, mm, lib and so on. This can be done step by step. So let's take an easier solution: add support to efficient unaligned access and hide the support under NONPORTABLE. Now let's introduce RISCV_EFFICIENT_UNALIGNED_ACCESS which depends on NONPORTABLE, if users know during config time that the kernel will be only run on those efficient unaligned access hw platforms, they can enable it. Obviously, generic unified kernel Image shouldn't enable it.

ring-buffer: Remove stale comment from ring_buffer_size()

The comment in the code is more of what a change log should have and is pretty much useless for development. It's saying how things worked back in 2012 that bares no purpose on today's code.

riscv: Allow disabling of BUILTIN_DTB for XIP
This enables, among other things, testing with the QEMU virt machine. To build an XIP kernel for the QEMU virt machine, configure the the kernel as desired and apply the following configuration ``` CONFIG_NONPORTABLE=y CONFIG_XIP_KERNEL=y CONFIG_XIP_PHYS_ADDR=0x20000000 CONFIG_PHYS_RAM_BASE=0x80200000 CONFIG_BUILTIN_DTB=n ``` Since the QEMU virt flash memory expects a 32 MB file, the built image must be padded. For example, with `truncate -s 32M arch/riscv/boot/xipImage` The kernel can be started using the following command in QEMU (v8+) ``` qemu-system-riscv64 -M virt,pflash0=pflash0 \ -blockdev node-name=pflash0,driver=file,read-only=on,\ filename=arch/riscv/boot/xipImage <optional parameters> ``` Signed-off-by: Frederik Haxel <haxel@fzi.de> Link: https://lore.kernel.org/r/20231212130116.848530-4-haxel@fzi.de Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com> |

ksmbd: free ppace array on error in parse_dacl
The ppace array is not freed if one of the init_acl_state() calls inside
parse_dacl() fails. At the moment the function may fail only due to the
memory allocation errors so it's highly unlikely in this case but
nevertheless a fix is needed.
Move ppace allocation after the init_acl_state() calls with proper error
handling.

linux_kselftest-kunit-6.8-rc1
This KUnit update for Linux 6.8-rc1 consists of:
- a new feature that adds APIs for managing devices introducing
a set of helper functions which allow devices (internally a
struct kunit_device) to be created and managed by KUnit.
These devices will be automatically unregistered on
test exit. These helpers can either use a user-provided
struct device_driver, or have one automatically created and
managed by KUnit. In both cases, the device lives on a new
kunit_bus.
- changes to switch drm/tests to use kunit devices
- several fixes and enhancements to attribute feature
- changes to reorganize deferred action function introducing
KUNIT_DEFINE_ACTION_WRAPPER
- new feature adds ability to run tests after boot using debugfs
- fixes and enhancements to string-stream-test:
- parse ERR_PTR in string_stream_destroy()
- unchecked dereference in bug fix in debugfs_print_results()
- handling errors from alloc_string_stream()

Pull KUnit updates from Shuah Khan:
- a new feature that adds APIs for managing devices introducing a set
of helper functions which allow devices (internally a struct
kunit_device) to be created and managed by KUnit.
These devices will be automatically unregistered on test exit. These
helpers can either use a user-provided struct device_driver, or have
one automatically created and managed by KUnit. In both cases, the
device lives on a new kunit_bus.
- changes to switch drm/tests to use kunit devices
- several fixes and enhancements to attribute feature
- changes to reorganize deferred action function introducing
KUNIT_DEFINE_ACTION_WRAPPER
- new feature adds ability to run tests after boot using debugfs
- fixes and enhancements to string-stream-test:
- parse ERR_PTR in string_stream_destroy()
- unchecked dereference in bug fix in debugfs_print_results()
- handling errors from alloc_string_stream()
- NULL-dereference bug fix in kunit_init_suite()

Pull power management updates from Rafael Wysocki:
"These add support for new processors (Sierra Forest, Grand Ridge and
Meteor Lake) to the intel_idle driver, make intel_pstate run on
Emerald Rapids without HWP support and adjust it to utilize EPP values
supplied by the platform firmware, fix issues, clean up code and
improve documentation.
The most significant fix addresses deadlocks in the core system-wide
resume code that occur if async_schedule_dev() attempts to run its
argument function synchronously (for example, due to a memory
allocation failure). It rearranges the code in question which may
increase the system resume time in some cases, but this basically is a
removal of a premature optimization. That optimization will be added
back later, but properly this time.
Specifics:
- Add support for the Sierra Forest, Grand Ridge and Meteorlake SoCs
to the intel_idle cpuidle driver (Artem Bityutskiy, Zhang Rui)

- Fix possible deadlocks in the core system-wide PM code that occur
if device-handling functions cannot be executed asynchronously
during resume from system-wide suspend (Rafael J. Wysocki)

Pull thermal control updates from Rafael Wysocki:
"These add support for the D1/T113s THS controller to the sun8i driver
and a DT-based mechanism for platforms to indicate a preference to
reboot (instead of shutting down) on crossing a critical trip point,
fix issues, make other improvements (in the IPA governor, the Intel
HFI driver, the exynos driver and the thermal netlink interface among
other places) and clean up code.
One long-standing issue addressed here is that trip point crossing
notifications sent to user space might be unreliable due to the
incorrect handling of trip point hysteresis in the thermal core:
multiple notifications might be sent for the same event or there might
be events without any notification at all.

Pull ACPI updates from Rafael Wysocki:
"From the new features standpoint, the most significant change here is
the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI
device enumeration code that will allow MIPI cameras to be enumerated
through the platform firmware on systems using ACPI.
Also significant is the switch-over to threaded interrupt handlers for
the ACPI SCI and the dedicated EC interrupt (on systems where the
former is not used) which essentially allows all ACPI code to run with
local interrupts enabled. That should improve responsiveness
significantly on systems where multiple GPEs are enabled and the
handling of one SCI involves many I/O address space accesses which
previously had to be carried out in one go with disabled interrupts on
the local CPU.
Apart from the above, the ACPI thermal zone driver will use the
Thermal fast Sampling Period (_TFP) object if available, which should
allow temperature changes to be followed more accurately on some
systems, the ACPI Notify () handlers can run on all CPUs (not just on
CPU0), which should generally speed up the processing of events
signaled through the ACPI SCI, and the ACPI power button driver will
trigger wakeup key events via the input subsystem (on systems where it
is a system wakeup device)
In addition to that, there are the usual bunch of fixes and cleanups.

cxl/pci: Register for and process CPER events
If the firmware has configured CXL event support to be firmware first the OS can process those events through CPER records. The CXL layer has unique DPA to HPA knowledge and standard event trace parsing in place. CPER records contain Bus, Device, Function information which can be used to identify the PCI device which is sending the event. Change the PCI driver registration to include registration of a CXL CPER callback to process events through the trace subsystem. Use new scoped based management to simplify the handling of the PCI device object.

PCI: Introduce cleanup helpers for device reference counts and locks
The "goto error" pattern is notorious for introducing subtle resource
leaks. Use the new cleanup.h helpers for PCI device reference counts and
locks.
Similar to the new put_device() and device_lock() cleanup helpers,
__free(put_device) and guard(device), define the same for PCI devices,
__free(pci_dev_put) and guard(pci_dev). These helpers eliminate the
need for "goto free;" and "goto unlock;" patterns. For example, A
'struct pci_dev *' instance declared as:
struct pci_dev *pdev __free(pci_dev_put) = NULL;
...will automatically call pci_dev_put() if @pdev is non-NULL when @pdev
goes out of scope (automatic variable scope). If a function wants to
invoke pci_dev_put() on error, but return @pdev on success, it can do:
return no_free_ptr(pdev);
...or:
return_ptr(pdev);
For potential cleanup opportunity there are 587 open-coded calls to
pci_dev_put() in the kernel with 65 instances within 10 lines of a goto
statement with the CXL driver threatening to add another one.
The guard() helper holds the associated lock for the remainder of the
current scope in which it was invoked. So, for example:
func(...)
{
if (...) {
...
guard(pci_dev); /* pci_dev_lock() invoked here */
...
} /* <- implied pci_dev_unlock() triggered here */
}
There are 15 invocations of pci_dev_unlock() in the kernel with 5
instances within 10 lines of a goto statement. Again, the CXL driver is
threatening to add another.
Introduce these helpers to preclude the addition of new more error prone
goto put; / goto unlock; sequences. For now, these helpers are used in
drivers/cxl/pci.c to allow ACPI error reports to be fed back into the
CXL driver associated with the PCI device identified in the report.

BIOS can configure memory devices as firmware first. This will send CXL events to the firmware instead of the OS. The firmware can then send these events to the OS via UEFI. UEFI v2.10 section N.2.14 defines a Common Platform Error Record (CPER) format for CXL Component Events. The format is mostly the same as the CXL Common Event Record Format. The difference is the use of a GUID in the Section Type rather than a UUID as part of the event itself. Add GHES support to detect CXL CPER records and call a registered callback with the event. A notifier chain was considered for the callback but the complexity did not justify the use case as only the CXL subsystem requires this event. Enforce that only one callback can be registered at any time. Cc: Ard Biesheuvel <ardb@kernel.org> Cc: Rafael J.

cxl/events: Create a CXL event union
The CXL CPER and event log records share everything but a UUID/GUID in their structures. Define a cxl_event union without the UUID/GUID to be shared between the CPER and event log record formats. Adjust the code to use this union.

* MTD
Apart from preventing the mtdblk to run on top of ftl or ubiblk (which
may cause security issues and has no meaning anyway), there are a few
misc fixes.
* Raw NAND
Two meaningful changes this time. The conversion of the brcmnand driver
to the ->exec_op() API, this series brought additional changes to the
core in order to help controller drivers to handle themselves the WP pin
during destructive operations when relevant.
There is also a series bringing important fixes to the sequential read
feature.
As always, there is as well a whole bunch of miscellaneous W=1 fixes,
together with a few runtime fixes (double free, timeout value, OOB
layout, missing register initialization) and the usual load of remove
callbacks turned into void (which led to switch the txx9ndfmc driver to
use module_platform_driver()).
* SPI NOR
SPI NOR comes with die erase support for multi die flashes, with new
octal protocols (1-1-8 and 1-8-8) parsed from SFDP and with an updated
documentation about what the contributors shall consider when proposing
flash additions or updates.
Michael Walle stepped out from the reviewer role to maintainer.

cxl/events: Separate UUID from event structures
The UEFI CXL CPER structure does not include the UUID. Now that the UUID is passed separately to the trace event there is no need to have the UUID in those structures. Move UUID from the event record header to the raw structures. Adjust cxl-test to Create dummy structures for creating test records.

cxl/events: Remove passing a UUID to known event traces
The UUID data is redundant in the known event trace types. The addition of static defines allows the trace macros to create the UUID data inside the trace thus removing unnecessary code. Have well known trace events use static data to set the uuid field based on the event type.
