2025-01-13net/mlx5: fs, add support for dest vport HWS actionMoshe Shemesh
Add support for HW Steering action of vport destination. Add dest vport actions cache. Hold action in cache per vport / vport and vhca_id. Add action to cache on demand and remove on namespace closure to reduce actions creation and destroy.

2025-01-13net/mlx5: fs, manage flow counters HWS action sharing by refcountMoshe Shemesh
Multiple flow counters can utilize a single Hardware Steering (HWS) action for Hardware Steering rules. Given that these counter bulks are not exclusively created for Hardware Steering, but also serve purposes such as statistics gathering and other steering modes, it's more efficient to create the HWS action only when it's first needed by a Hardware Steering rule. This approach allows for better resource management through the use of a reference count, rather than automatically creating an HWS action for every bulk of flow counters.

2025-01-13eth: iavf: extend the netdev_lock usageJakub Kicinski
iavf uses the netdev->lock already to protect shapers. In an upcoming series we'll try to protect NAPI instances with netdev->lock. We need to modify the protection a bit. All NAPI related calls in the driver need to be consistently under the lock. This will allow us to easily switch to a "we already hold the lock" NAPI API later. register_netdevice(), OTOH, must not be called under the netdev_lock() as we do not intend to have an "already locked" version of this call.

2025-01-13ACPI: video: Fix random crashes due to bad kfree()Chris Bainbridge
Commit c6a837088bed ("drm/amd/display: Fetch the EDID from _DDC if available for eDP") added function dm_helpers_probe_acpi_edid(), which fetches the EDID from the BIOS by calling acpi_video_get_edid(). acpi_video_get_edid() returns a pointer to the EDID, but this pointer does not originate from kmalloc() - it is actually the internal "pointer" field from an acpi_buffer struct (which did come from kmalloc()). dm_helpers_probe_acpi_edid() then attempts to kfree() the EDID pointer, resulting in memory corruption which leads to random, intermittent crashes (e.g. 4% of boots will fail with some Oops). Fix this by allocating a new array (which can be safely freed) for the EDID data, and correctly freeing the acpi_buffer pointer. The only other caller of acpi_video_get_edid() is nouveau_acpi_edid(): remove the extraneous kmemdup() here as the EDID data is now copied in acpi_video_device_EDID().

Also it asks to disable and then re-enable the PLL lock bit, after the factor changes have been applied. Add clock notifiers for the PLL and the CPU mux clock, using the existing notifier callbacks, and tell them to use mux 4 (the PLL_PERI0(1X) source), and bit 29 (the LOCK_ENABLE) bit.

2025-01-13ice: Fix quad registers read on E825Karol Kolacinski
Quad registers are read/written incorrectly. E825 devices always use quad 0 address and differentiate between the PHYs by changing SBQ destination device (phy_0 or phy_0_peer). Add helpers for reading/writing PTP registers shared per quad and use correct quad address and SBQ destination device based on port.

2025-01-13md/md-bitmap: move bitmap_{start, end}write to md upper layerYu Kuai
There are two BUG reports that raid5 will hang at bitmap_startwrite([1],[2]), root cause is that bitmap start write and end write is unbalanced, it's not quite clear where, and while reviewing raid5 code, it's found that bitmap operations can be optimized. For example, for a 4 disks raid5, with chunksize=8k, if user issue a IO (0 + 48k) to the array: ┌────────────────────────────────────────────────────────────┐ │chunk 0 │ │ ┌────────────┬─────────────┬─────────────┬────────────┼ │ sh0 │A0: 0 + 4k │A1: 8k + 4k │A2: 16k + 4k │A3: P │ │ ┼────────────┼─────────────┼─────────────┼────────────┼ │ sh1 │B0: 4k + 4k │B1: 12k + 4k │B2: 20k + 4k │B3: P │ ┼──────┴────────────┴─────────────┴─────────────┴────────────┼ │chunk 1 │ │ ┌────────────┬─────────────┬─────────────┬────────────┤ │ sh2 │C0: 24k + 4k│C1: 32k + 4k │C2: P │C3: 40k + 4k│ │ ┼────────────┼─────────────┼─────────────┼────────────┼ │ sh3 │D0: 28k + 4k│D1: 36k + 4k │D2: P │D3: 44k + 4k│ └──────┴────────────┴─────────────┴─────────────┴────────────┘ Before this patch, 4 stripe head will be used, and each sh will attach bio for 3 disks, and each attached bio will trigger bitmap_startwrite() once, which means total 12 times. - 3 times (0 + 4k), for (A0, A1 and A2) - 3 times (4 + 4k), for (B0, B1 and B2) - 3 times (8 + 4k), for (C0, C1 and C3) - 3 times (12 + 4k), for (D0, D1 and D3) After this patch, md upper layer will calculate that IO range (0 + 48k) is corresponding to the bitmap (0 + 16k), and call bitmap_startwrite() just once. Noted that this patch will align bitmap ranges to the chunks, for example, if user issue a IO (0 + 4k) to array: - Before this patch, 1 time (0 + 4k), for A0; - After this patch, 1 time (0 + 8k) for chunk 0; Usually, one bitmap bit will represent more than one disk chunk, and this doesn't have any difference. And even if user really created a array that one chunk contain multiple bits, the overhead is that more data will be recovered after power failure. Also remove STRIPE_BITMAP_PENDING since it's not used anymore.

2025-01-13md/raid5: implement pers->bitmap_sector()Yu Kuai
Bitmap is used for the whole array for raid1/raid10, hence IO for the array can be used directly for bitmap. However, bitmap is used for underlying disks for raid5, hence IO for the array can't be used directly for bitmap. Implement pers->bitmap_sector() for raid5 to convert IO ranges from the array to the underlying disks.

For the case that IO failed for one rdev, the bit will be mark as NEEDED in following cases: 1) If badblocks is set and rdev is not faulty; 2) If rdev is faulty; Case 1) is useless because synchronize data to badblocks make no sense. Case 2) can be replaced with mddev->degraded. Also remove R1BIO_Degraded, R10BIO_Degraded and STRIPE_DEGRADED since case 2) no longer use them.

2025-01-13hwmon: (pwm-fan) Default to the Maximum cooling level if providedPeter Korsgaard
The pwm-fan driver uses full PWM (255) duty cycle at startup, which may not always be desirable because of noise or power consumption peaks. The driver optionally accept a list of "cooling-levels" for the thermal subsystem. If provided, use the PWM value corresponding to the maximum cooling level rather than the full level as the initial PWM setting.

2025-01-13md: Replace deprecated kmap_atomic() with kmap_local_page()David Reaver
kmap_atomic() is deprecated and should be replaced with kmap_local_page() [1][2]. kmap_local_page() is faster in kernels with HIGHMEM enabled, can take page faults, and allows preemption. According to [2], this is safe as long as the code between kmap_atomic() and kunmap_atomic() does not implicitly depend on disabling page faults or preemption. It appears to me that none of the call sites in this patch depend on disabling page faults or preemption; they are all mapping a page to simply extract some information from it or print some debug info.

2025-01-13md: reintroduce md-linearYu Kuai
THe md-linear is removed by commit 849d18e27be9 ("md: Remove deprecated CONFIG_MD_LINEAR") because it has been marked as deprecated for a long time. However, md-linear is used widely for underlying disks with different size, sadly we didn't know this until now, and it's true useful to create partitions and assemble multiple raid and then append one to the other. People have to use dm-linear in this case now, however, they will prefer to minimize the number of involved modules.

2025-01-13mmc: hi3798mv200: Use syscon_regmap_lookup_by_phandle_argsKrzysztof Kozlowski
Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over syscon_regmap_lookup_by_phandle() combined with getting the syscon argument. Except simpler code this annotates within one line that given phandle has arguments, so grepping for code would be easier. There is also no real benefit in printing errors on missing syscon argument, because this is done just too late: runtime check on static/build-time data. Dtschema and Devicetree bindings offer the static/build-time check for this already.
