2024-11-13s390/cio: Externalize full CMG characteristicsPeter Oberparleiter
The current "measurement_chars" CHPID sysfs attribute exposes only a limited, validity-filtered portion of data from the associated Channel- Measurements Characteristics Block (CMCB). New machine models add data that is relevant for userspace tooling to the "header"-portion of the CMCB. This data that is not currently accessible to userspace. To prevent having to add new sysfs attributes whenever a new bit of data is added to the CMCB "header", add a new sysfs attribute named "measurement_chars_full" that exposes the full, unfiltered CMCB.

2024-11-13spi: cs42l43: Add GPIO speaker id support to the bridge configurationSimon Trimmer
OEMs can use the spk-id-gpios ACPI property to indicate the type of speakers fitted to a device. Attempt to read a spk-id value using the GPIO method when a usable spk-id value is not obtained from the 01fa-spk-id-val ACPI property. Obtaining the spk-id value has been moved earlier in the function to the other sidecar block, so that an -EPROBE_DEFER from a GPIO driver is handled more efficiently.

By switching to the new flexible sleeping helper function, fsleep(), the correct delay function is called depending on delay length, e.g. udelay(), usleep_range() or msleep().

2024-11-13clocksource/drivers/mips-gic-timer: Always use cluster 0 counter as clocksourcePaul Burton
In a multi-cluster MIPS system, there are multiple GICs - one in each cluster - each of which has its independent counter. The counters in each GIC are not synchronized in any way, so they can drift relative to one another through the lifetime of the system. This is problematic for a clock source which ought to be global. Avoid problems by always accessing cluster 0's counter, using cross-cluster register access. This adds overhead so it is applied only on multi-cluster systems.

This config is overly restrictive, while platforms that rely on the SP804 do select it in their Kconfig there are others such as the Arm fast models which have a SP804 available but currently unused by Linux. Relax the dependency to allow it to be user selectable on arm and arm64 to avoid surprises and in case someone comes up with a use for extra timer hardware.

2024-11-12eth: bnxt: use page pool for head fragsJakub Kicinski
Testing small size RPCs (300B-400B) on a large AMD system suggests that page pool recycling is very useful even for just the head frags. With this patch (and copy break disabled) I see a 30% performance improvement (82Gbps -> 106Gbps). Convert bnxt from normal page frags to page pool frags for head buffers. On systems with small page size we can use the same pool as for TPA pages. On systems with large pages the frag allocation logic of the page pool is already used to split a large page into TPA chunks. TPA chunks are much larger than heads (8k or 64k, AFAICT vs 1kB) and we always allocate the same sized chunks. Mixing allocation of TPA and head pages would lead to sub-optimal memory use. Plus Taehee's work on zero-copy / devmem will need to differentiate between TPA and non-TPA page pool, anyway. Conditionally allocate a new page pool for heads.

2024-11-12Revert "igb: Disable threaded IRQ for igb_msix_other"Wander Lairson Costa
This reverts commit 338c4d3902feb5be49bfda530a72c7ab860e2c9f. Sebastian noticed the ISR indirectly acquires spin_locks, which are sleeping locks under PREEMPT_RT, which leads to kernel splats.

2024-11-13cpufreq: maple: Remove maple driverMichael Ellerman
This driver is no longer buildable since the PPC_MAPLE platform was removed, see commit 62f8f307c80e ("powerpc/64: Remove maple platform"). Remove the driver. Note that the comment in the driver says it supports "SMU & 970FX based G5 Macs", but that's not true, that comment was copied from pmac64-cpufreq.c, which still exists and continues to support those machines.

2024-11-13drm/panthor: Fix handling of partial GPU mapping of BOsAkash Goel
This commit fixes the bug in the handling of partial mapping of the buffer objects to the GPU, which caused kernel warnings. Panthor didn't correctly handle the case where the partial mapping spanned multiple scatterlists and the mapping offset didn't point to the 1st page of starting scatterlist. The offset variable was not cleared after reaching the starting scatterlist. Following warning messages were seen.

2024-11-12virtio_vdpa: remove redundant check on descColin Ian King
The boolean variable has_affinity is true when desc is non-null and ops->set_vq_affinity is non-null. Hence the call to create_affinity_masks does not need to check for desc being non-null is redundant when has_affinity is true, so it can be removed as well as the now unused default_affd.
