2024-11-13thermal: 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/thermal 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. On the way make a few whitespace changes to make indention consistent.

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.

Representor and NIC shares the code but representors netdev support subset of NIC functionality. Hence "otx2_rep_dev" API helps to skip the features initialization that are not supported by the representors.

2024-11-13ACPI: video: force native for Apple MacbookPro11,2 and Air7,2Jonathan Denose
There is a bug in the Macbook Pro 11,2 and Air 7,2 firmware similar to what is described in: commit 7dc918daaf29 ("ACPI: video: force native for Apple MacbookPro9,2") This bug causes their backlights not to come back after resume. Add DMI quirks to select the working native Intel firmware interface such that the backlght comes back on after resume.

2024-11-13ACPI: CPPC: Fix _CPC register setting issueLifeng Zheng
Since commit 60949b7b8054 ("ACPI: CPPC: Fix MASK_VAL() usage"), _CPC registers cannot be changed from 1 to 0. It turns out that there is an extra OR after MASK_VAL_WRITE(), which has already ORed prev_val with the register mask. Remove the extra OR to fix the problem.

2024-11-13irqchip/loongson-eiointc: Add virt extension supportBibo Mao
Interrupts can be routed to maximal four virtual CPUs with real HW EIOINTC interrupt controller model, since interrupt routing is encoded with CPU bitmap and EIOINTC node combined method. Here add the EIOINTC virt extension support so that interrupts can be routed to 256 vCPUs in virtual machine mode. CPU bitmap is replaced with normal encoding and EIOINTC node type is removed, so there are 8 bits for cpu selection, at most 256 vCPUs are supported for interrupt routing.

2024-11-12hwmon: (cros_ec) register thermal sensors to thermal frameworkSung-Chi, Li
cros_ec hwmon driver probes available thermal sensors when probing the driver. Register these thermal sensors to the thermal framework as well via setting HWMON_C_REGISTER_TZ as a chip info, such that thermal framework can adopt these sensors as well. To make cros_ec registrable to thermal framework, the cros_ec dts need the corresponding changes: &cros_ec { #thermal-sensor-cells = <1>; }; Signed-off-by: Sung-Chi, Li <lschyi@chromium.org> Message-ID: <20241113024000.3327161-1-lschyi@chromium.org> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
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.
