2024-11-13cpufreq: intel_pstate: Update Balance-performance EPP for Granite RapidsSrinivas Pandruvada
Update EPP default for balance_performance to 32. This will give better performance out of the box using Intel P-State powersave governor while still offering power savings compared to performance governor. This is in line with what has already been done for Emerald Rapids and Sapphire Rapids.

2024-11-13octeontx2-pf: Add representors for sdp MACGeetha sowjanya
Hardware supports different types of MACs eg RPM, SDP, LBK. LBK is for internal Tx->Rx HW loopback path. RPM and SDP MACs support ingress/egress pkt IO on interfaces with different set of capabilities like interface modes. At the time of netdev driver registration PF will seek MAC related information from Admin function driver 'drivers/net/ethernet/marvell/octeontx2/af' and sets up ingress/egress queues etc such that pkt IO on the channels of these different MACs is possible.

When representor is put under a bridge and pkts needs to be sent to representee, then pkts from representor are sent on a HW internal loopback channel, which again will be punted to ingress pkt parser. Now the rules that this patch installs are the MCAM filters/rules which will match against these pkts and forward them to representee. The rules that this patch installs are for basic representor <=> representee path similar to Tun/TAP between VM and Host.

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.

2024-11-12hwmon: (pwm-fan) Introduce start from stopped state handlingMarek Vasut
Delta AFC0612DB-F00 fan has to be set to at least 30% PWM duty cycle to spin up from a stopped state, and can be afterward throttled down to lower PWM duty cycle. Introduce support for operating such fans which need to start at higher PWM duty cycle first and can slow down next. Introduce two new DT properties, "fan-stop-to-start-percent" and "fan-stop-to-start-us". The former describes the minimum percent of fan RPM at which it will surely spin up from stopped state. This value can be found in the fan datasheet and can be converted to PWM duty cycle easily. The "fan-stop-to-start-us" describes the minimum time in microseconds for which the fan has to be set to stopped state start RPM for the fan to surely spin up. Adjust the PWM setting code such that if the PWM duty cycle is below the minimum duty cycle needed by the fan to spin up from stopped state, then first set the PWM duty cycle to the minimum duty cycle needed by the fan to spin up from stopped state, then wait the time necessary for the fan to spin up from stopped state, and finally set the PWM duty cycle to the one desired by user.

This prevents use of this driver with ACPI via PRP0001 and is an example of an anti pattern I'm trying to remove from the kernel. Hence drop from this driver. Also switch of.h for mod_devicetable.h include given use of struct of_device_id which is defined in that header.

2024-11-12hwmon: (pmbus/core) clear faults after setting smbalert maskJerome Brunet
pmbus_write_smbalert_mask() ignores the errors if the chip can't set smbalert mask the standard way. It is not necessarily a problem for the irq support if the chip is otherwise properly setup but it may leave an uncleared fault behind. pmbus_core will pick the fault on the next register_check(). The register check will fails regardless of the actual register support by the chip. This leads to missing attributes or debugfs entries for chips that should provide them. We cannot rely on register_check() as PMBUS_SMBALERT_MASK may be read-only. Unconditionally clear the page fault after setting PMBUS_SMBALERT_MASK to avoid the problem.

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.

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.
