2023-10-20efi/unaccepted: Fix soft lockups caused by parallel memory acceptanceKirill A. Shutemov
Michael reported soft lockups on a system that has unaccepted memory. This occurs when a user attempts to allocate and accept memory on multiple CPUs simultaneously. The root cause of the issue is that memory acceptance is serialized with a spinlock, allowing only one CPU to accept memory at a time. The other CPUs spin and wait for their turn, leading to starvation and soft lockup reports. To address this, the code has been modified to release the spinlock while accepting memory. This allows for parallel memory acceptance on multiple CPUs. A newly introduced "accepting_list" keeps track of which memory is currently being accepted. This is necessary to prevent parallel acceptance of the same memory block. If a collision occurs, the lock is released and the process is retried. Such collisions should rarely occur. The main path for memory acceptance is the page allocator, which accepts memory in MAX_ORDER chunks. As long as MAX_ORDER is equal to or larger than the unit_size, collisions will never occur because the caller fully owns the memory block being accepted. Aside from the page allocator, only memblock and deferered_free_range() accept memory, but this only happens during boot. The code has been tested with unit_size == 128MiB to trigger collisions and validate the retry codepath. Fixes: 2053bc57f367 ("efi: Add unaccepted memory support") Signed-off-by: Kirill A.

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.7 This introduces partial support for the Qualcomm Secure Execution Environment SCM interface, and uses this to implement EFI variable access on the Windows On Snapdragon devices (for now). The 32/64-bit calling convention detector of the SCM interface is updated to not choose 64-bit convention when Linux is 32-bit. The "extern" specifier is dropped from the interface include file. The LLCC driver gains support for carrying configuration for multiple different system/DDR configurations for a given platform, and selecting between them. Support for Q[DR]U1000 is added to the driver. All exported symbols are transitioned to EXPORT_SYMBOL_GPL(). The platform_drivers in the Qualcomm SoC are transitioned to the void-returning remove_new implementation. The rmtfs memory driver gains support for leaving guard pages around the used area, to avoid issues if the allocation happens to be placed adjacent to another protected memory region. The socinfo driver gains knowledge about IPQ8174, QCM6490, SM7150P and various PMICs used together with SM8550. * tag 'qcom-drivers-for-6.7' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (44 commits) soc: qcom: socinfo: Convert to platform remove callback returning void soc: qcom: smsm: Convert to platform remove callback returning void soc: qcom: smp2p: Convert to platform remove callback returning void soc: qcom: smem: Convert to platform remove callback returning void soc: qcom: rmtfs_mem: Convert to platform remove callback returning void soc: qcom: qcom_stats: Convert to platform remove callback returning void soc: qcom: qcom_gsbi: Convert to platform remove callback returning void soc: qcom: qcom_aoss: Convert to platform remove callback returning void soc: qcom: pmic_glink: Convert to platform remove callback returning void soc: qcom: ocmem: Convert to platform remove callback returning void soc: qcom: llcc-qcom: Convert to platform remove callback returning void soc: qcom: icc-bwmon: Convert to platform remove callback returning void firmware: qcom_scm: use 64-bit calling convention only when client is 64-bit soc: qcom: llcc: Handle a second device without data corruption soc: qcom: Switch to EXPORT_SYMBOL_GPL() soc: qcom: smem: Annotate struct qcom_smem with __counted_by soc: qcom: rmtfs: Support discarding guard pages dt-bindings: reserved-memory: rmtfs: Allow guard pages dt-bindings: firmware: qcom,scm: document IPQ5018 compatible firmware: qcom_scm: disable SDI if required ...

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm FF-A updates for v6.7 The main addition is the initial support for the notifications and memory transaction descriptor changes added in FF-A v1.1 specification. The notification mechanism enables a requester/sender endpoint to notify a service provider/receiver endpoint about an event with non-blocking semantics. A notification is akin to the doorbell between two endpoints in a communication protocol that is based upon the doorbell/mailbox mechanism. The framework is responsible for the delivery of the notification from the ender to the receiver without blocking the sender. The receiver endpoint relies on the OS scheduler for allocation of CPU cycles to handle a notification. OS is referred as the receiver’s scheduler in the context of notifications. The framework is responsible for informing the receiver’s scheduler that the receiver must be run since it has a pending notification.

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.7 Main additions this time include: 1. SCMI v3.2 clock configuration support: This helps to retrieve the enabled state of a clock as well as allow to set OEM specific clock configurations. 2. Support for generic performance scaling(DVFS): The current SCMI DVFS support is limited to the CPUs in the kernel. This extension enables it to used for all kind of devices and not only for the CPUs. It updates the SCMI cpufreq to utilize the power domain bindings. It also adds a more generic SCMI performance domain based on the genpd framework that as be used for all the non-CPU devices. 3. Extend the generic performance scaling(DVFS) support for firmware driver OPPs: Consumer drivers for devices that are attached to the SCMI performance domain can't make use of the current OPP library to scale performance as the OPPs are firmware driven and often obtained from the firmware rather than the device tree. These changes extend the generic OPP and genpd PM domain frameworks to identify and utilise these firmware driven OPPs. 4. SCMI v3.2 clock parent support: This enables the support for discovering and changing parent clocks and extending the SCMI clk driver to use the same. 5. Qualcom SMC/HVC transport support: The Qualcomm virtual platforms require capability id in the hypervisor call to identify which doorbell to assert when supporting multiple SMC/HVC based SCMI transport channels. Extra parameter is added to support the same and the same is obtained at the fixed address in the shared memory which is initialised by the firmware. 6. Move the existing SCMI power domain driver under drivers/pmdomain Apart from the above main changes, it also include couple of minor fixes and cosmetic reworks. * tag 'scmi-updates-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: (37 commits) firmware: arm_scmi: Add qcom smc/hvc transport support dt-bindings: arm: Add new compatible for smc/hvc transport for SCMI firmware: arm_scmi: Convert u32 to unsigned long to align with arm_smccc_1_1_invoke() clk: scmi: Add support for clock {set,get}_parent firmware: arm_scmi: Add support for clock parents clk: scmi: Free scmi_clk allocated when the clocks with invalid info are skipped firmware: arm_scpi: Use device_get_match_data() firmware: arm_scmi: Add generic OPP support to the SCMI performance domain firmware: arm_scmi: Specify the performance level when adding an OPP firmware: arm_scmi: Simplify error path in scmi_dvfs_device_opps_add() OPP: Extend support for the opp-level beyond required-opps OPP: Switch to use dev_pm_domain_set_performance_state() OPP: Extend dev_pm_opp_data with a level OPP: Add dev_pm_opp_add_dynamic() to allow more flexibility PM: domains: Implement the ->set_performance_state() callback for genpd PM: domains: Introduce dev_pm_domain_set_performance_state() firmware: arm_scmi: Rename scmi_{msg_,}clock_config_{get,set}_{2,21} firmware: arm_scmi: Do not use !! on boolean when setting msg->flags firmware: arm_scmi: Move power-domain driver to the pmdomain dir pmdomain: arm: Add the SCMI performance domain ...

2023-10-13firmware: tegra: Add suspend hook and reset BPMP IPC early on resumeSumit Gupta
Add suspend hook and a 'suspended' field in the 'struct tegra_bpmp' to mark if BPMP is suspended. Also, add a 'flags' field in the 'struct tegra_bpmp_message' whose 'TEGRA_BPMP_MESSAGE_RESET' bit can be set from the Tegra MC driver to signal that the reset of BPMP IPC channels is required before sending MRQ to the BPMP FW. Together both the fields allow us to handle any requests that might be sent too soon as they can cause hang during system resume. One case where we see BPMP requests being sent before the BPMP driver has resumed is the memory bandwidth requests which are triggered by onlining the CPUs during system resume. The CPUs are onlined before the BPMP has resumed and we need to reset the BPMP IPC channels to handle these requests. The additional check for 'flags' is done to avoid any un-intended BPMP IPC reset if the tegra_bpmp_transfer*() API gets called during suspend sequence after the BPMP driver is suspended.

The capability-id is used to identify the doorbell from the VM's capability namespace, similar to a file-descriptor. The hypervisor, in addition to the function-id, expects the capability-id to be passed in x1 register when SMC/HVC call is invoked.

2023-10-06firmware: arm_ffa: Initial support for scheduler receiver interruptSudeep Holla
The Framework uses the schedule receiver interrupt to inform the receiver’s scheduler that the receiver must be run to handle a pending notification. A receiver’s scheduler can obtain the description of the schedule receiver interrupt by invoking the FFA_FEATURES interface. The delivery of the physical schedule receiver interrupt from the secure state to the non-secure state depends upon the state of the interrupt controller as configured by the hypervisor. The schedule seceiver interrupt is assumed to be a SGI. The Arm GIC specification defines 16 SGIs. It recommends that they are equally divided between the non-secure and secure states. OS like Linux kernel in the non-secure state typically do not have SGIs to spare. The usage of SGIs in the secure state is however limited. It is more likely that software in the Secure world does not use all the SGIs allocated to it. It is recommended that the secure world software donates an unused SGI to the normal world for use as the schedule receiver interrupt. This implies that secure world software must configure the SGI in the GIC as a non-secure interrupt before presenting it to the normal world.

2023-10-06firmware: arm_ffa: Implement the NOTIFICATION_INFO_GET interfaceSudeep Holla
The receiver’s scheduler uses the FFA_NOTIFICATION_INFO_GET interface to retrieve the list of endpoints that have pending notifications and must be run. A notification could be signaled by a sender in the secure world to a VM. The Hypervisor needs to determine which VM and vCPU (in case a per-vCPU notification is signaled) has a pending notification in this scenario. It must obtain this information through an invocation of the FFA_NOTIFICATION_INFO_GET. Add the implementation of the NOTIFICATION_INFO_GET interface and prepare to use this to handle the schedule receiver interrupt. Implementation of handling notifications will be added later.

2023-10-06firmware: arm_ffa: Implement the notification bind and unbind interfaceSudeep Holla
A receiver endpoint must bind a notification to any sender endpoint before the latter can signal the notification to the former. The receiver assigns one or more doorbells to a specific sender. Only the sender can ring these doorbells. A receiver uses the FFA_NOTIFICATION_BIND interface to bind one or more notifications to the sender. A receiver un-binds a notification from a sender endpoint to stop the notification from being signaled. It uses the FFA_NOTIFICATION_UNBIND interface to do this. Allow the FF-A driver to be able to bind and unbind a given notification ID to a specific partition ID. This will be used to register and unregister notification callbacks from the FF-A client drivers.
