2024-01-10virtio_pmem: support feature SHMEM_REGIONChangyuan Lyu
This patch adds the support for feature VIRTIO_PMEM_F_SHMEM_REGION (virtio spec v1.2 section 5.19.5.2 [1]). During feature negotiation, if VIRTIO_PMEM_F_SHMEM_REGION is offered by the device, the driver looks for a shared memory region of id 0. If it is found, this feature is understood. Otherwise, this feature bit is cleared. During probe, if VIRTIO_PMEM_F_SHMEM_REGION has been negotiated, virtio pmem ignores the `start` and `size` fields in device config and uses the physical address range of shared memory region 0.

2024-01-10virtio_balloon: stay awake while adjusting balloonDavid Stevens
A virtio_balloon's parent device may be configured so that a configuration change interrupt is a wakeup event. Extend the processing of such a wakeup event until the balloon finishes inflating or deflating by calling pm_stay_awake/pm_relax in the virtio_balloon driver. Note that these calls are no-ops if the parent device doesn't support wakeup events or if the wakeup events are not enabled. This change allows the guest to use system power states such as s2idle without running the risk the virtio_balloon's cooperative memory management becoming unresponsive to the host's requests.

2024-01-10riscv: errata: thead: use riscv_nonstd_cache_ops for CMOJisheng Zhang
Previously, we use alternative mechanism to dynamically patch the CMO operations for THEAD C906/C910 during boot for performance reason. But as pointed out by Arnd, "there is already a significant cost in accessing the invalidated cache lines afterwards, which is likely going to be much higher than the cost of an indirect branch". And indeed, there's no performance difference with GMAC and EMMC per my test on Sipeed Lichee Pi 4A board. Use riscv_nonstd_cache_ops for THEAD C906/C910 CMO to simplify the alternative code, and to acchieve Arnd's goal -- "I think moving the THEAD ops at the same level as all nonstandard operations makes sense, but I'd still leave CMO as an explicit fast path that avoids the indirect branch. This seems like the right thing to do both for readability and for platforms on which the indirect branch has a noticeable overhead."

2024-01-10block: fix partial zone append completion handling in req_bio_endio()Damien Le Moal
Partial completions of zone append request is not allowed but if a zone append completion indicates a number of completed bytes different from the original BIO size, only the BIO status is set to error. This leads to bio_advance() not setting the BIO size to 0 and thus to not call bio_endio() at the end of req_bio_endio(). Make sure a partially completed zone append is failed and completed immediately by forcing the completed number of bytes (nbytes) to be equal to the BIO size, thus ensuring that bio_endio() is called.

On some Meteor Lake platforms, maximum one core turbo frequency is not observed. During hybrid performance to frequency conversion, the maximum frequency is 100 MHz less. This results in requesting maximum frequency 100 MHz less. For example when the max one core turbo is 4.9 GHz: MSR HWP_CAPABILITIES shows highest performance ratio for P-core is 0x3E. With the current scaling factor of 78741 (1.27x for converting frequency to performance) results in max frequency of 4.8 GHz. This results in capping the max scaling frequency as 4.8 GHz, which is 100 MHz less than the desired. Add capability to define per CPU model specific scaling factor and define scaling factor of 80000 (1.25x for converting frequency to performance for P-cores) for Meteor Lake.

2024-01-10firewire: core: fill model field in modalias of unit device for legacy ↵Takashi Sakamoto
layout of configuration ROM As the last part of support for legacy layout of configuration ROM, this commit traverses vendor directory as well as root directory when constructing modalias for unit device. The change brings loss of backward compatibility since it can fill model field ('mo') which is 0 at current implementation in the case. However, we can be optimistic against regression for unit drivers in kernel, due to some points: 1. ALSA drivers for audio and music units use the model fields to match device, however all of supported devices does not have such legacy layout. 2. the other unit drivers (e.g. sbp2) does not use the model field to match device. The rest of concern is user space application. The most of applications just take care of node device and does not use the modalias of unit device, thus the change does not affect to them. But systemd project is known to get affects from the change since it includes hwdb to take udev to configure fw character device conveniently. I have a plan to work for systemd so that the access permission of character device could be kept across the change.

intel_wakeref_t is supposed to be a mostly opaque cookie to its users. It should only be checked for being non-zero and set to zero. Debug logging its actual value is meaningless.

2024-01-10drm/i915/dp: Fix the PSR debugfs entries wrt. MST connectorsImre Deak
MST connectors don't have a static attached encoder, as their encoder can change depending on the pipe they use; so the encoder for an MST connector can't be retrieved using intel_dp_attached_encoder() (which may return NULL for MST). Most of the PSR debugfs entries depend on a static connector -> encoder mapping which is only true for eDP and SST DP connectors and not for MST. These debugfs entries were enabled for MST connectors as well recently to provide PR information for them, but handling MST connectors needs more changes. Fix this by not adding for now the PSR entries on MST connectors. To make things more uniform add the entries for SST connectors on all platforms, not just on platforms supporting DP2.0. v2: - Keep adding the entries for SST connectors. (Jouni) - Add a TODO: comment for MST support.

2024-01-09Input: driver for Adafruit Seesaw GamepadAnshul Dalal
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)` Product page: https://www.adafruit.com/product/5743 Arduino driver: https://github.com/adafruit/Adafruit_Seesaw Driver tested on RPi Zero 2W Reviewed-by: Thomas Weißschuh <linux@weissschuh.net> Signed-off-by: Anshul Dalal <anshulusr@gmail.com> Link: https://lore.kernel.org/r/20240106015111.882325-2-anshulusr@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2024-01-09riscv: introduce RISCV_EFFICIENT_UNALIGNED_ACCESSJisheng Zhang
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.
