It integrates pm_runtime in the core for keeping resources active while the remote is booted and holds a wake source while recoverying a remote processor after a firmware crash. It refactors the remoteproc device's allocation path to simplify the logic, fix a few cleanup bugs and to not clone const strings onto the heap. Debugfs code is simplifies using the DEFINE_SHOW_ATTRIBUTE and a zero-length array is replaced with flexible-array. A new remoteproc driver for the JZ47xx VPU is introduced, the Qualcomm SM8250 gains support for audio, compute and sensor remoteprocs and the Qualcomm SC7180 modem support is cleaned up and improved. The Qualcomm glink subsystem-restart driver is merged into the main glink driver, the Qualcomm sysmon driver is extended to properly notify remote processors about all other remote processors' state transitions" * tag 'rproc-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc: (43 commits) remoteproc: Fix an error code in devm_rproc_alloc() MAINTAINERS: Add myself as reviewer for Ingenic rproc driver remoteproc: ingenic: Added remoteproc driver remoteproc: Add support for runtime PM dt-bindings: Document JZ47xx VPU auxiliary processor remoteproc: wcss: Fix arguments passed to qcom_add_glink_subdev() remoteproc: Fix and restore the parenting hierarchy for vdev remoteproc: Fall back to using parent memory pool if no dedicated available remoteproc: Replace zero-length array with flexible-array remoteproc: wcss: add support for rpmsg communication remoteproc: core: Prevent system suspend during remoteproc recovery remoteproc: qcom_q6v5_mss: Remove unused q6v5_da_to_va function remoteproc: qcom_q6v5_mss: map/unmap mpss segments before/after use remoteproc: qcom_q6v5_mss: Drop accesses to MPSS PERPH register space dt-bindings: remoteproc: qcom: Replace halt-nav with spare-regs remoteproc: qcom: pas: Add SM8250 PAS remoteprocs dt-bindings: remoteproc: qcom: pas: Add SM8250 remoteprocs remoteproc: qcom_q6v5_mss: Extract mba/mpss from memory-region dt-bindings: remoteproc: qcom: Use memory-region to reference memory remoteproc: qcom: pas: Add SC7180 Modem support ...

* / cpuidle: Convert Qualcomm SPM driver to a generic CPUidle driverStephan Gerhold2020-05-261-10/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | The Qualcomm SPM cpuidle driver seems to be the last driver still using the generic ARM CPUidle infrastructure. Converting it actually allows us to simplify the driver, and we end up being able to remove more lines than adding new ones: - We can parse the CPUidle states in the device tree directly with dt_idle_states (and don't need to duplicate that functionality into the spm driver). - Each "saw" device managed by the SPM driver now directly registers its own cpuidle driver, removing the need for any global (per cpu) state. The device tree binding is the same, so the driver stays compatible with all old device trees.

| | | | | | | | | | | | | Qualcomm SoCs (starting with MSM8998) allow for multiple protection domains to run on the same Q6 sub-system. This allows for services like ATH10K WLAN FW to have their own separate address space and crash/recover without disrupting the modem and other PDs running on the same sub-system. The PDR helpers introduces an abstraction that allows for tracking/controlling the life cycle of protection domains running on various Q6 sub-systems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OCMEM driver handles allocation and configuration of the On Chip MEMory that is present on some Snapdragon SoCs. Devices which have OCMEM do not have GMEM inside the GPU core, so the GPU must instead use OCMEM to be functional. Since the GPU is currently the only OCMEM user with an upstream driver, this is just a minimal implementation sufficient for statically allocating to the GPU it's chunk of OCMEM. This driver currently does not read the gmu-sram node that is described in the device tree bindings. The starting memory address of the GPU's reserved memory region is hardcoded to zero to match what the hardware expects. The driver can be updated to read the reserved memory regions from device tree once other users of OCMEM are added upstream.

The communication is a very simple synchronous mechanism of messages being written in message RAM and a doorbell in the AOSS is rung. As the AOSS has processed the message length is cleared and an interrupt is fired by the AOSS as acknowledgment. The driver exposes the QDSS clock as a clock and the low-power state associated with the remoteprocs in the system as a set of power-domains.

* soc: qcom: rpmhpd: Add RPMh power domain driverRajendra Nayak2019-01-221-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RPMh power domain driver aggregates the corner votes from various consumers for the ARC resources and communicates it to RPMh. With RPMh we use 2 different numbering space for corners, one used by the clients to express their performance needs, and another used to communicate to RPMh hardware. The clients express their performance requirements using a sparse numbering space which are mapped to meaningful levels like RET, SVS, NOMINAL, TURBO etc which then get mapped to another number space between 0 and 15 which is communicated to RPMh. The sparse number space, also referred to as vlvl is mapped to the continuous number space of 0 to 15, also referred to as hlvl, using command DB. Some power domain clients could request a performance state only while the CPU is active, while some others could request for a certain performance state all the time regardless of the state of the CPU. We handle this by internally aggregating the votes from both type of clients and then send the aggregated votes to RPMh. There are also 3 different types of votes that are comunicated to RPMh for every resource. 1. ACTIVE_ONLY: This specifies the requirement for the resource when the CPU is active 2. SLEEP: This specifies the requirement for the resource when the CPU is going to sleep 3. WAKE_ONLY: This specifies the requirement for the resource when the CPU is coming out of sleep to active state We add data for all power domains on sdm845 SoC as part of the patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add controller driver for QCOM SoCs that have hardware based shared resource management. The hardware IP known as RSC (Resource State Coordinator) houses multiple Direct Resource Voter (DRV) for different execution levels. A DRV is a unique voter on the state of a shared resource. A Trigger Control Set (TCS) is a bunch of slots that can house multiple resource state requests, that when triggered will issue those requests through an internal bus to the Resource Power Manager Hardened (RPMH) blocks. These hardware blocks are capable of adjusting clocks, voltages, etc. The resource state request from a DRV are aggregated along with state requests from other processors in the SoC and the aggregate value is applied on the resource. Some important aspects of the RPMH communication - - Requests are <addr, value> with some header information - Multiple requests (upto 16) may be sent through a TCS, at a time - Requests in a TCS are sent in sequence - Requests may be fire-n-forget or completion (response expected) - Multiple TCS from the same DRV may be triggered simultaneously - Cannot send a request if another request for the same addr is in progress from the same DRV - When all the requests from a TCS are complete, an IRQ is raised - The IRQ handler needs to clear the TCS before it is available for reuse - TCS configuration is specific to a DRV - Platform drivers may use DRV from different RSCs to make requests Resource state requests made when CPUs are active are called 'active' state requests. Requests made when all the CPUs are powered down (idle state) are called 'sleep' state requests. They are matched by a corresponding 'wake' state requests which puts the resources back in to previously requested active state before resuming any CPU. TCSes are dedicated for each type of requests. Active mode TCSes (AMC) are used to send requests immediately to the resource, while control TCS are used to provide specific information to the controller. Sleep and Wake TCS send sleep and wake requests, after and before the system halt respectively.

| | | | | | | | | | | | | | | | By moving these client drivers to use RPMSG instead of the direct SMD API we can reuse them ontop of the newly added GLINK wire-protocol support found in the 820 and 835 Qualcomm platforms. As the new (RPMSG-based) and old SMD implementations are mutually exclusive we have to change all client drivers in one commit, to make sure we have a working system before and after this transition.
