2024-11-12cpufreq: ACPI: Simplify MSR read on the boot CPUChang S. Bae
Replace the 32-bit MSR access function with a 64-bit variant to simplify the call site, eliminating unnecessary 32-bit value manipulations. Signed-off-by: Chang S.

2024-11-12ACPI: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/acpi to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

2024-11-12ACPI: x86: Add adev NULL check to acpi_quirk_skip_serdev_enumeration()Hans de Goede
acpi_dev_hid_match() does not check for adev == NULL, dereferencing it unconditional. Add a check for adev being NULL before calling acpi_dev_hid_match(). At the moment acpi_quirk_skip_serdev_enumeration() is never called with a controller_parent without an ACPI companion, but better safe than sorry.

2024-11-12ACPI: x86: Make UART skip quirks work on PCI UARTs without an UIDHans de Goede
The Vexia EDU ATLA 10 tablet (9V version) which shipped with Android 4.2 as factory OS has the usual broken DSDT issues for x86 Android tablets. On top of that this tablet is special because all its LPSS island peripherals are enumerated as PCI devices rather then as ACPI devices as they typically are. For the x86-android-tablets kmod to be able to instantiate a serdev client for the Bluetooth HCI on this tablet, an ACPI_QUIRK_UART1_SKIP quirk is necessary. Modify acpi_dmi_skip_serdev_enumeration() to work with PCI enumerated UARTs without an UID, such as the UARTs on this tablet. Also make acpi_dmi_skip_serdev_enumeration() exit early if there are no quirks, since there is nothing to do then. And add the necessary quirks for the Vexia EDU ATLA 10 tablet. This should compile with CONFIG_PCI being unset without issues because dev_is_pci() is defined as "(false)" then.

2024-11-12mmc: pwrseq_simple: Handle !RESET_CONTROLLER properlyStefan Wahren
The recent introduction of reset control in pwrseq_simple introduced a regression for platforms without RESET_CONTROLLER support, because devm_reset_control_get_optional_shared() would return NULL and make all resets no-ops. Instead of enforcing this dependency, rely on this behavior to determine reset support. As a benefit we can get the rid of the use_reset flag.

In the probe function, it goes to 'release_mem' label and returns after some procedure failure. But if the clocks (partial or all) have been enabled previously, they would not be disabled in msdc_runtime_suspend, since runtime PM is not yet enabled for this case. That cause mmc related clocks always on during system suspend and block suspend flow.

2024-11-12mmc: sunxi-mmc: Fix A100 compatible descriptionAndre Przywara
It turns out that the Allwinner A100/A133 SoC only supports 8K DMA blocks (13 bits wide), for both the SD/SDIO and eMMC instances. And while this alone would make a trivial fix, the H616 falls back to the A100 compatible string, so we have to now match the H616 compatible string explicitly against the description advertising 64K DMA blocks. As the A100 is now compatible with the D1 description, let the A100 compatible string point to that block instead, and introduce an explicit match against the H616 string, pointing to the old description. Also remove the redundant setting of clk_delays to NULL on the way.

https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.13 Just couple of main additions: 1. Support for variable I/O width within ARM SCMI shared memory area. Some shared memory areas might only support a certain access width, such as 32-bit, which memcpy_{from,to}_io() does not adhere to at least on ARM64 by making both 8-bit and 64-bit accesses to such memory. This support updates the shmem layer to support reading from and writing to such shared memory area using the specified I/O width in the Device Tree. The various transport layers making use of the shmem.c code are updated accordingly to pass the I/O accessors that they store. The device tree bindings are also updated for the same. 2. Extension of SCMI transport bindings to add more properties SCMI transports are characterized by a number of properties. The values assumed by some of them tightly depend on the choices taken at design time and on the overall archiecture of the specific platform: things like timeouts, maximum message size and number of in-flight messages are closely tied to the architecture of the platform like number of SCMI agents on the system, physical memory available to the SCMI platform and so on. Such details are not discoverable as they are outside the scope of the SCMI protocol specification. Currently such properties are simple default values defined at build time, but the increasing number and variety of platforms using SCMI with a wide range of designs has increased the need to have a way to describe such properties across all these platforms. Apart from the above two, there is one NULL pointer dereference fix for very age old SCPI protocol driver which seems to be still in use on few platforms. * tag 'scmi-updates-6.13' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scpi: Check the DVFS OPP count returned by the firmware firmware: arm_scmi: Relocate atomic_threshold to scmi_desc firmware: arm_scmi: Use max_msg and max_msg_size devicetree properties dt-bindings: firmware: arm,scmi: Introduce more transport properties firmware: arm_scmi: Calculate virtio PDU max size dynamically firmware: arm_scmi: Account for SHMEM memory overhead firmware: arm_scmi: Support 'reg-io-width' property for shared memory dt-bindings: sram: Document reg-io-width property firmware: arm_scmi: Use vendor string in max-rx-timeout-ms dt-bindings: firmware: arm,scmi: Add missing vendor string firmware: arm_scmi: Reject clear channel request on A2P firmware: arm_scmi: Fix slab-use-after-free in scmi_bus_notifier() Link: https://lore.kernel.org/r/20241106110727.4007489-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2024-11-12regulator: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/regulator to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. A few whitespace changes are done en passant to make indention consistent.

2024-11-12intel-hid: fix volume buttons on Thinkpad X12 Detachable Tablet Gen 1Cole Stowell
Volume buttons on Lenovo Thinkpad X12 Detachable Tablet Gen 1 did not send any input events when pressed. When loading intel-hid with the 5 Button Array explicitly enabled, the buttons functioned normally. Adds the X12 Detachable Tablet Gen 1 to the `button_array_table`. However, the driver is unable to call INTEL_HID_DSM_BTNE_FN and prints the warning "failed to set button capability" when attempting to enable or disable the 5 Button Array. The warning should be harmless and adding more special handling to avoid it is not worth it.

2024-11-12platform/x86: asus-wmi: Fix inconsistent use of thermal policiesArmin Wolf
When changing the thermal policy using the platform profile API, a Vivobook thermal policy is stored in throttle_thermal_policy_mode. However everywhere else a normal thermal policy is stored inside this variable, potentially confusing the platform profile. Fix this by always storing normal thermal policy values inside throttle_thermal_policy_mode and only do the conversion when writing the thermal policy to hardware. This also fixes the order in which throttle_thermal_policy_switch_next() steps through the thermal modes on Vivobook machines.

And the issue seems to be that the corresponding devres group is not allocated. Normally, devres_open_group() is called from __hid_device_probe() but Hyper-V HID driver overrides 'hid_dev->driver' with 'mousevsc_hid_driver' stub and basically re-implements __hid_device_probe() by calling hid_parse() and hid_hw_start() but not devres_open_group(). hid_device_probe() does not call __hid_device_probe() for it. Later, when the driver is removed, hid_device_remove() calls devres_release_group() as it doesn't check whether hdev->driver was initially overridden or not. The issue seems to be related to the commit 62c68e7cee33 ("HID: ensure timely release of driver-allocated resources") but the commit itself seems to be correct. Fix the issue by dropping the 'hid_dev->driver' override and using hid_register_driver()/hid_unregister_driver() instead. Alternatively, it would have been possible to rely on the default handling but HID_CONNECT_DEFAULT implies HID_CONNECT_HIDRAW and it doesn't seem to work for mousevsc as-is.

All MTL and ARL SKUs share the same GSC FW, but the newer platforms are only supported in newer blobs. In particular, ARL-S is supported starting from 102.0.10.1878 (which is already the minimum required version for ARL in the code), while ARL-H and ARL-U are supported from 102.1.15.1926. Therefore, the driver needs to check which specific ARL subplatform its running on when verifying that the GSC FW is new enough for it.

2024-11-11net/mlx5e: SHAMPO, Drop info arrayDragos Tatulea
The info array is used to store a pointer to the dma address of the header and to the frag page. However, this array is not really required: - The frag page can be calculated from the header index frag page index = header index / headers per page. - The dma address can be calculated through a formula: dma page address + header offset. This series gets rid of the info array and uses the above formulas instead. The current_page_index was used in conjunction with the info array to store page fragment indices. This variable is dropped as well. There was no performance regression observed.

Now that the UMR allocation has been simplified, it is no longer possible to have a leftover page from a previous call to mlx5e_build_shampo_hd_umr(). This patch simplifies the code by switching the order of operations: first take the frag page and then increment the index.

2024-11-11net/mlx5e: SHAMPO, Fix page_index calculation inconsistencyDragos Tatulea
When calculating the index for the next frag page slot, the divisor is incorrect: it should be the number of pages per queue not the number of headers per queue. This is currently harmless because frag pages are not used directly, but they are intermediated through the info array. But it needs to be fixed as an upcoming patch will get rid of the info array. This patch introduces a new pages per queue variable and plugs it in the formula. Now that this variable exists, additional code can be simplified in the SHAMPO initialization code.

2024-11-11net/mlx5e: SHAMPO, Simplify UMR allocation for headersDragos Tatulea
Allocating page fragments for header data split is currently more complicated than it should be. That's because the number of KSM entries allocated is not aligned to the number of headers per page. This leads to having leftovers in the next allocation which require additional accounting and needlessly complicated code. This patch aligns (down) the number of KSM entries in the UMR WQE to the number of headers per page by: 1) Aligning the max number of entries allocated per UMR WQE (max_ksm_entries) to MLX5E_SHAMPO_WQ_HEADER_PER_PAGE. 2) Aligning the total number of free headers to MLX5E_SHAMPO_WQ_HEADER_PER_PAGE. ... and then it drops the extra accounting code from mlx5e_build_shampo_hd_umr(). Although the number of entries allocated per UMR WQE is slightly smaller due to aligning down, no performance impact was observed.
