2026-04-06ASoC: qcom: Constify GPR packet being send over GPR interfaceKrzysztof Kozlowski1-2/+2
gpr_send_pkt() and pkt_router_send_svc_pkt() only send the GPR packet they receive, without any need to actually modify it, so mark the pointer to GPR packet as pointer to const for code safety and code self-documentation. Several users of this interface can follow up and also operate on pointer to const.

2026-03-30soc: qcom: ubwc: add helpers to get programmable valuesDmitry Baryshkov1-0/+15
Currently the database stores macrotile_mode in the data. However it can be derived from the rest of the data: it should be used for UBWC encoding >= 3.0 except for several corner cases (SM8150 and SC8180X). The ubwc_bank_spread field seems to be based on the impreside data we had for the MDSS and DPU programming. In some cases UBWC engine inside the display controller doesn't need to program it, although bank spread is to be enabled. Bank swizzle is also currently stored as is, but it is almost standard (banks 1-3 for UBWC 1.0 and 2-3 for other versions), the only exception being Lemans (it uses only bank 3). Add helpers returning values from the config for now. They will be rewritten later, in a separate series, but having the helper now simplifies refacroring the code later.

2026-03-15soc: qcom: qmi: Enumerate the service IDs of QMIDaniel Lezcano1-0/+12
The QMI framework proposes a set of services which are defined by an integer identifier. The different QMI client lookup for the services via this identifier. Moreover, the function qmi_add_lookup() and qmi_add_server() must match the service ID but the code in different places set the same value but with a different macro name. These macros are spreaded across the different subsystems implementing the protocols associated with a service. It would make more sense to define them in the QMI header for the sake of consistency and clarity. This change use an unified naming for the services and enumerate the ones implemented in the Linux kernel. More services can come later and put the service ID in this same header.

Fix incorrect slice activation/deactivation accounting by replacing the bitmap-based activation tracking with per-slice atomic reference counters. This resolves mismatches that occur when multiple client drivers vote for the same slice or when llcc_slice_getd() is called multiple times. As part of this fix, simplify slice descriptor handling by eliminating dynamic allocation. llcc_slice_getd() now returns a pointer to a preallocated descriptor, removing the need for repeated allocation/free cycles and ensuring consistent reference tracking across all users.

qcom_mdt_pas_init() was previously used only by the remoteproc driver (drivers/remoteproc/qcom_q6v5_pas.c). Since that driver has now transitioned to using PAS context-based qcom_mdt_pas_load() function, making qcom_mdt_pas_init() obsolete for external use.

Introduce a new PAS context-aware function, qcom_mdt_pas_load(), for remote processor drivers. This function utilizes the PAS context pointer returned from qcom_scm_pas_ctx_init() to perform firmware metadata verification and memory setup via SMC calls. The qcom_mdt_pas_load() and qcom_mdt_load() functions are largely similar, but the former is designed for clients using the PAS context-based data structure. Over time, all users of qcom_mdt_load() can be migrated to use qcom_mdt_pas_load() for consistency and improved abstraction. As the remoteproc PAS driver (qcom_q6v5_pas) has already adopted the PAS context-based approach, update it to use qcom_mdt_pas_load().

As discussed a lot in the past, the UBWC config must be coherent across a number of IP blocks (currently display and GPU, but it also may/will concern camera/video as the drivers evolve). So far, we've been trying to keep the values reasonable in each of the two drivers separately, but it really make sense to do so centrally, especially given certain fields (e.g. HBB) may need to be gathered dynamically. To reduce room for error, move to fetching the config from a central source, so that the data programmed into the hardware is consistent across all multimedia blocks that request it.

2024-08-21soc: qcom: pmic_glink: Fix race during initializationBjorn Andersson1-5/+6
As pointed out by Stephen Boyd it is possible that during initialization of the pmic_glink child drivers, the protection-domain notifiers fires, and the associated work is scheduled, before the client registration returns and as a result the local "client" pointer has been initialized. The outcome of this is a NULL pointer dereference as the "client" pointer is blindly dereferenced. Timeline provided by Stephen: CPU0 CPU1 ---- ---- ucsi->client = NULL; devm_pmic_glink_register_client() client->pdr_notify(client->priv, pg->client_state) pmic_glink_ucsi_pdr_notify() schedule_work(&ucsi->register_work) <schedule away> pmic_glink_ucsi_register() ucsi_register() pmic_glink_ucsi_read_version() pmic_glink_ucsi_read() pmic_glink_ucsi_read() pmic_glink_send(ucsi->client) <client is NULL BAD> ucsi->client = client // Too late! This code is identical across the altmode, battery manager and usci child drivers. Resolve this by splitting the allocation of the "client" object and the registration thereof into two operations. This only happens if the protection domain registry is populated at the time of registration, which by the introduction of commit '1ebcde047c54 ("soc: qcom: add pd-mapper implementation")' became much more likely.

Handling of optional L1TCM memory is made actually optional. - An optimization is introduced to only clear the unused portion of IPI shared buffers, rather than the entire buffer before writing the message. - Detection for IPC-only mode in the TI K3 DSP remoteproc driver is corrected. The loglevel of a debug print in the same is lowered from error. - Support for attaching to an running remote processor is added to the Xilinx R5F. - An in-kernel implementation of the Qualcomm "protected domain mapper" (aka service registry) service is introduced, to remove the dependency on a userspace implementation to detect when the battery monitor and USB Type-C port manager becomes available. This is then integrated with the Qualcomm remoteproc driver. - The Qualcomm PAS remoteproc driver gains support for attempting to bust hwspinlocks held by the remote processor when it crashed/stopped. - The TI OMAP remoteproc driver is transitioned to use devres helpers for various forms of allocations. - Parsing of memory-regions in the i.MX remoteproc driver is improved to avoid a NULL pointer dereference if the phandle reference is empty. of_node reference counting is corrected in the same. * tag 'rproc-v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: remoteproc: mediatek: Increase MT8188/MT8195 SCP core0 DRAM size remoteproc: k3-dsp: Fix log levels where appropriate remoteproc: xlnx: Add attach detach support remoteproc: qcom: select AUXILIARY_BUS remoteproc: k3-r5: Fix IPC-only mode detection remoteproc: mediatek: Don't attempt to remap l1tcm memory if missing remoteproc: qcom: enable in-kernel PD mapper dt-bindings: remoteproc: imx_rproc: Add minItems for power-domain remoteproc: imx_rproc: Fix refcount mistake in imx_rproc_addr_init remoteproc: omap: Use devm_rproc_add() helper remoteproc: omap: Use devm action to release reserved memory remoteproc: omap: Use devm_rproc_alloc() helper remoteproc: imx_rproc: Skip over memory region when node value is NULL dt-bindings: remoteproc: k3-dsp: Correct optional sram properties for AM62A SoCs remoteproc: qcom_q6v5_pas: Add hwspinlock bust on stop soc: qcom: smem: Add qcom_smem_bust_hwspin_lock_by_host() remoteproc: mediatek: Zero out only remaining bytes of IPI buffer
2024-07-03driver core: have match() callback in struct bus_type take a const *Greg Kroah-Hartman1-1/+1
In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: Rafael J.

2024-06-21soc: qcom: smem: Add a feature code getterKonrad Dybcio2-0/+27
Recent (SM8550+ ish) Qualcomm SoCs have a new mechanism for precisely identifying the specific SKU and the precise speed bin (in the general meaning of this word, anyway): a pair of values called Product Code and Feature Code. Based on this information, we can deduce the available frequencies for things such as Adreno. In the case of Adreno specifically, Pcode is useless for non-prototype SoCs. Introduce a getter for the feature code and export it.

2024-05-31soc: qcom: llcc: Add regmap for Broadcast_AND regionUnnathi Chalicheemala1-1/+3
Until SM8450, there was only one broadcast region (Broadcast_OR) used to broadcast write and check for status bit 0. >From SM8450 onwards another broadcast region (Broadcast_AND) has been added which checks for status bit 1. This hasn't been updated and Broadcast_OR region was wrongly being used to check for status bit 1 all along. Hence define new regmap structure for Broadcast_AND region and initialize this regmap when HW block version is greater than 4.1, otherwise initialize as a NULL pointer for backwards compatibility. Switch from broadcast_OR to broadcast_AND region (when defined in DT) for checking status bit 1 as Broadcast_OR region checks only for bit 0.

Add qcom_smem_bust_hwspin_lock_by_host to enable remoteproc to bust the hwspin_lock owned by smem. In the event the remoteproc crashes unexpectedly, the remoteproc driver can invoke this API to try and bust the hwspin_lock and release the lock if still held by the remoteproc device.
