2024-06-20firmware: psci: Fix return value from psci_system_suspend()Sudeep Holla
Currently we return the value from invoke_psci_fn() directly as return value from psci_system_suspend(). It is wrong to send the PSCI interface return value directly. psci_to_linux_errno() provide the mapping from PSCI return value to the one that can be returned to the callers within the kernel. Use psci_to_linux_errno() to convert and return the correct value from psci_system_suspend().

2024-06-15efi/x86: Free EFI memory map only when installing a new one.Ard Biesheuvel
The logic in __efi_memmap_init() is shared between two different execution flows: - mapping the EFI memory map early or late into the kernel VA space, so that its entries can be accessed; - the x86 specific cloning of the EFI memory map in order to insert new entries that are created as a result of making a memory reservation via a call to efi_mem_reserve(). In the former case, the underlying memory containing the kernel's view of the EFI memory map (which may be heavily modified by the kernel itself on x86) is not modified at all, and the only thing that changes is the virtual mapping of this memory, which is different between early and late boot. In the latter case, an entirely new allocation is created that carries a new, updated version of the kernel's view of the EFI memory map. When installing this new version, the old version will no longer be referenced, and if the memory was allocated by the kernel, it will leak unless it gets freed. The logic that implements this freeing currently lives on the code path that is shared between these two use cases, but it should only apply to the latter. So move it to the correct spot. While at it, drop the dummy definition for non-x86 architectures, as that is no longer needed.

2024-06-14firmware: arm_scmi: Add support for platform to agent channel completionPeng Fan
On some systems the SCMI platform to agent(p2a) communication can be fully interrupt driven. The notification(p2a) channel needs completion interrupt to drive its notification queue at the platform. Without it, the platform notification will not work as the platform will wait for agent indication of clearing the channel via interrupt unlike few platforms which can poll instead. To support such systems, an optional unidirectional mailbox channel for p2a reply communication. If the platform sets channel INTR flag set indicating that it expects the agent to trigger the interrupt to acknowledge the reciept of the notification or any p2a message, and the completion interrupt channel is provided, send a mailbox message to the platform after the p2a message is read and channel is freed to accept new notifications or p2a messages.

2024-06-10ARM: 9404/1: arm32: enable HAVE_LD_DEAD_CODE_DATA_ELIMINATIONYuntao Liu
The current arm32 architecture does not yet support the HAVE_LD_DEAD_CODE_DATA_ELIMINATION feature. arm32 is widely used in embedded scenarios, and enabling this feature would be beneficial for reducing the size of the kernel image. In order to make this work, we keep the necessary tables by annotating them with KEEP, also it requires further changes to linker script to KEEP some tables and wildcard compiler generated sections into the right place. When using ld.lld for linking, KEEP is not recognized within the OVERLAY command, and Ard proposed a concise method to solve this problem. It boots normally with defconfig, vexpress_defconfig and tinyconfig. The size comparison of zImage is as follows: defconfig vexpress_defconfig tinyconfig 5137712 5138024 424192 no dce 5032560 4997824 298384 dce 2.0% 2.7% 29.7% shrink When using smaller config file, there is a significant reduction in the size of the zImage. We also tested this patch on a commercially available single-board computer, and the comparison is as follows: a15eb_config 2161384 no dce 2092240 dce 3.2% shrink The zImage size has been reduced by approximately 3.2%, which is 70KB on 2.1M.

2024-06-05efi: Add missing __nocfi annotations to runtime wrappersArd Biesheuvel
The EFI runtime wrappers are a sandbox for calling into EFI runtime services, which are invoked using indirect calls. When running with kCFI enabled, the compiler will require the target of any indirect call to be type annotated. Given that the EFI runtime services prototypes and calling convention are governed by the EFI spec, not the Linux kernel, adding such type annotations for firmware routines is infeasible, and so the compiler must be informed that prototype validation should be omitted. Add the __nocfi annotation at the appropriate places in the EFI runtime wrapper code to achieve this. Note that this currently only affects 32-bit ARM, given that other architectures that support both kCFI and EFI use an asm wrapper to call EFI runtime services, and this hides the indirect call from the compiler.

2024-05-29firmware: arm_ffa: Move the FF-A v1.0 NULL UUID workaround to bus notifierSudeep Holla
Currently FF-A bus ffa_device_match() handles the workaround for the FF-A v1.0 devices which are not populated with UUID to match. The FF-A bus layer calls into FF-A driver and populates the device UUID if it matches with the driver attempting to match. But this forces to have both FF-A bus and core driver to be bundled into a single module. However, keep it as a single module adds problems for the FF-A driver registrations and their initcall levels. In preparation to split the FF-A bus and the core driver into distinct modules, we need to move the workaround away from the FF-A bus layer. We can add it into the FF-A core driver as a bus notifier. In order to do so, we need to always match any driver with the device if the UUID is NULL and then during the driver binding phase, we can populate the UUID if it matches with the driver UUID table using the bus notifiers. We also need to add a check for NULL UUID before calling the device/driver probe as devices with NULL UUID is possible since we match all for that case.

2024-05-17x86/efistub: Omit physical KASLR when memory reservations existArd Biesheuvel
The legacy decompressor has elaborate logic to ensure that the randomized physical placement of the decompressed kernel image does not conflict with any memory reservations, including ones specified on the command line using mem=, memmap=, efi_fake_mem= or hugepages=, which are taken into account by the kernel proper at a later stage. When booting in EFI mode, it is the firmware's job to ensure that the chosen range does not conflict with any memory reservations that it knows about, and this is trivially achieved by using the firmware's memory allocation APIs. That leaves reservations specified on the command line, though, which the firmware knows nothing about, as these regions have no other special significance to the platform. Since commit a1b87d54f4e4 ("x86/efistub: Avoid legacy decompressor when doing EFI boot") these reservations are not taken into account when randomizing the physical placement, which may result in conflicts where the memory cannot be reserved by the kernel proper because its own executable image resides there. To avoid having to duplicate or reuse the existing complicated logic, disable physical KASLR entirely when such overrides are specified. These are mostly diagnostic tools or niche features, and physical KASLR (as opposed to virtual KASLR, which is much more important as it affects the memory addresses observed by code executing in the kernel) is something we can live without.

He also added support for the CAM1 camera interface regulator. - Uwe adds a pinctrl-based multiplexing description to allow the use of I2C0 pins to allow usage between the 40-pin Raspberry Pi header and the CSI and DSI connectors. He then describes the PCF85063 RTC device available on the CM4 I/O board making use of that pinctrl-based muxing. - Arinc updates the Asus RT-AC3100 and RT-AC88U DTs to have proper LED colors and function properties, NVMEM MAC addresses and removes duplicates and unnecessary properties and does a few Device Tree cleanups.. He then adds support for the Asus RT-AC3200 (BCM4709-based) and RT-AC3500 routers. - Jean-Michel adds DT nodes for the CSI Unicam camera interfaces on the Raspberry Pi 4 / BCM2711 SoCs - Florian adds support for the Ethernet LEDs on Raspberry Pi 4 B and Raspberry Pi 4 CM boards. * tag 'arm-soc/for-6.10/devicetree' of https://github.com/Broadcom/stblinux: arm: dts: bcm2711: Describe Ethernet LEDs ARM: dts: BCM5301X: Conform to DTS Coding Style on ASUS RT-AC3100 & AC88U ARM: dts: BCM5301X: Add DT for ASUS RT-AC5300 ARM: dts: BCM5301X: Add DT for ASUS RT-AC3200 dt-bindings: arm: bcm: add bindings for ASUS RT-AC5300 dt-bindings: arm: bcm: add bindings for ASUS RT-AC3200 ARM: dts: bcm2835: Add Unicam CSI nodes ARM: dts: BCM5301X: remove earlycon on ASUS RT-AC3100 and ASUS RT-AC88U ARM: dts: BCM5301X: remove duplicate compatible on ASUS RT-AC3100 & AC88U ARM: dts: BCM5301X: provide address for SoC MACs on ASUS RT-AC3100 & AC88U ARM: dts: BCM5301X: use color and function on ASUS RT-AC3100 and RT-AC88U ARM: dts: bcm2711-rpi-4-b: Add CAM1 regulator ARM: dts: bcm2711-rpi-cm4-io: Add RTC on I2C0 ARM: dts: bcm2711-rpi: Add pinctrl-based multiplexing for I2C0 ARM: dts: bcm2835-rpi: Move duplicate firmware-clocks to bcm2835-rpi.dtsi ARM: dts: bcm283x: Drop unneeded properties in the bcm2835-firmware node firmware: raspberrypi: Use correct device for DMA mappings dt-bindings: arm: bcm: raspberrypi,bcm2835-firmware: Add gpio child node Link: https://lore.kernel.org/r/20240429213703.2327834-2-florian.fainelli@broadcom.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm FF-A updates for v6.10 1. Support for handling notification pending interrupt(NPI) The FF-A uses the notification pending interrupt to inform the receiver that it has a pending notification. This is a virtual interrupt and is used by the following type of receivers: - A guest/VM running under a hypervisor(normal world usecase) - An S-EL1 SP running under a S-EL2 SPMC(secure world only usecase) Also, when the FF-A driver is running inside a guest VM under an hypervisor, the driver/guest VM doesn't have the permission/capability to request the creation of notification bitmaps. For a VM, the hypervisor reserves memory for its VM and hypervisor framework notification bitmaps and the SPMC reserves memory for its SP and SPMC framework notification bitmaps before the hypervisor initializes it. These changes include skipping of creation of notification bitmaps, some refactoring around schedule receiver interrupt(SRI) handling and addition of support for NPI. 2. Support for FF-A indirect messaging The FFA_MSG_SEND2 can be used to transmit a partition message from the Tx buffer of the sender(the driver in this case) endpoint to the Rx buffer of the receiver endpoint and inform the scheduler that the receiver endpoint must be run. Apart from these two main features, there is an optimisation to avoid queuing of a work when already running on the worker queue. * tag 'ffa-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_ffa: Avoid queuing work when running on the worker queue firmware: arm_ffa: Fix memory corruption in ffa_msg_send2() firmware: arm_ffa: Add support for FFA_MSG_SEND2 firmware: arm_ffa: Stash the partition properties for query purposes firmware: arm_ffa: Fix kernel warning about incorrect SRI/NPI firmware: arm_ffa: Add support for handling notification pending interrupt(NPI) firmware: arm_ffa: Refactor SRI handling in prepartion to add NPI support firmware: arm_ffa: Skip creation of the notification bitmaps Link: https://lore.kernel.org/r/20240426105051.1527016-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.10 1. Basic support for SCMI v3.2 pincontrol protocol SCMI v3.2 introduces pincontrol protocol which is intended for controlling pins and their configuration. The pin control protocol provides commands to: - List the pins, groups of pins, available functions, and their association with each other. - Set the parameter configuration and multiplexing of the pins or groups of pins - Optionally request exclusive access to a pin or group of pins. - Optionally configure the permissions of an agent to access a pin or group of pins. These changes adds basic support for the same in the SCMI core layer and an implementation of the generic scmi-pinctrl driver with associated DT bindings. 2. Framework support for multiple vendors custom protocols With the fixed space for vendor protocols, the possibility of having multiple vendors implementing distinct SCMI vendor protocols with the same overlapping protocol number is very high and with the need to support them all in a single kernel image or a module is also high. In order to implement the same we assume: - vendor protocols has to be tagged at build time with a vendor_id - vendor protocols could also optionally be tagged at build time with sub_vendor_id and implementation version At the initialisation all the built vendor protocols are registered with the SCMI core using a key derived from the above tags 3. Logging and tracing improvements This includes using dev_err_probe() to bail out from probe, adding message dump traces for bad and unexpected replies and widening of the tag buffer in trace_scmi_dump_msg to allow diverse tag names 4. Miscellaneous updates or improvements This includes adding the accessor function get_max_msg_size() used in pinctl protocol, updation of dt-bindings examples for protocol@13 to promote new bindings and simplification of scmi_devm_notifier_unregister * tag 'scmi-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: pinctrl: Implementation of the generic scmi-pinctrl driver firmware: arm_scmi: Add basic support for SCMI v3.2 pincontrol protocol dt-bindings: firmware: Support SCMI pinctrl protocol firmware: arm_scmi: Introduce get_max_msg_size() helper/accessor firmware: arm_scmi: Add support for multiple vendors custom protocols dt-bindings: firmware: arm,scmi: Update examples for protocol@13 firmware: arm_scmi: Avoid non-constant printk format strings firmware: arm_scmi: Use dev_err_probe to bail out firmware: arm_scmi: Simplify scmi_devm_notifier_unregister firmware: arm_scmi: Add message dump traces for bad and unexpected replies firmware: arm_scmi: Add helper to trace bad messages include: trace: Widen the tag buffer in trace_scmi_dump_msg firmware: arm_scmi: Log the perf domain names in the error paths Link: https://lore.kernel.org/r/20240426105031.1526987-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>
