remoteproc: qcom: enable in-kernel PD mapper

2024-06-25T14:40:38+00:00

Request in-kernel protection domain mapper to be started before starting Qualcomm DSP and release it once DSP is stopped. Once all DSPs are stopped, the PD mapper will be stopped too.

Merge tag 'rproc-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

2023-02-26T20:18:36+00:00

Pull remoteproc updates from Bjorn Andersson: - Support for PRU clients to acquire a control reference to the PRU instances is introduced, and the PRU now allows specifying firmware-name in Devicetree. sysfs is requested to be read-only when the remoteproc instance is consumed by another kernel driver - Support for the C7xv DSP on AM62A SoC is introduced - The Devicetree binding for the Qualcomm PAS devices are split up in multiple files, to better account for the differences in resources between them. A number of missing Devicetree bindings are added, and the Qualcomm WCNSS binding is converted to YAML - A few cleanups are introduced for the Mediatek SCP driver. And a sanity check of the firmware image is introduced in the Mediatek driver - For Qualcomm SC7280 ADSP support is added, MSM8953 gains ADSP and modem support, SM6115 and SM8550 gains ADSP, CDSP and modem support, and support for pronto v3 support (used on e.g. MSM8953) is added - The Qualcomm modem remoteproc driver is modified to use a no-map reserved-memory region for it's authentication metadata, in order to avoid fatal security violations caused by accesses from Linux during the authentication process - Support for separate loading of a Devicetree blob is added to the PAS driver, and support for the PAS driver to carve out DSM memory for the modem is added as well - The Qualcomm ADSP remoteproc driver gains support for mapping memory into specific range using the IOMMU. The sysmon driver is transitioned to strlcpy() * tag 'rproc-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: (69 commits) dt-bindings: mailbox: qcom,apcs-kpss-global: drop mbox-names from example dt-bindings: remoteproc: qcom,glink-edge: correct label description dt-bindings: remoteproc: qcom,glink-rpm-edge: convert to DT schema dt-bindings: remoteproc: qcom,sm8550-pas: correct power domains remoteproc: qcom_q6v5_pas: enable sm8550 adsp & cdsp autoboot dt-bindings: remoteproc: qcom: Add sm6115 pas yaml file remoteproc: qcom: pas: Add sm6115 remoteprocs remoteproc: qcom: pas: Adjust the phys addr wrt the mem region remoteproc: qcom: fix sparse warnings remoteproc: qcom: replace kstrdup with kstrndup remoteproc: mediatek: Check the SCP image format remoteproc: qcom_q6v5_mss: Use a carveout to authenticate modem headers Revert "remoteproc: qcom_q6v5_mss: map/unmap metadata region before/after use" dt-bindings: remoteproc: qcom,sc7280-mss-pil: Update memory-region dt-bindings: remoteproc: qcom,sc7180-mss-pil: Update memory-region dt-bindings: remoteproc: qcom,msm8996-mss-pil: Update memory region dt-bindings: remoteproc: qcom,q6v5: Move MSM8996 to schema remoteproc: qcom_q6v5_pas: add sm8550 adsp, cdsp & mpss compatible & data remoteproc: qcom_q6v5_pas: add support for assigning memory to firmware remoteproc: qcom_q6v5_pas: add support for dtb co-firmware loading ...

remoteproc: qcom: pas: Adjust the phys addr wrt the mem region

2023-02-14T17:04:29+00:00

The minidump table in the toc contains physical addresses that may lie before the physical address of the first elf segment in relocatable images. This change adds a custom dump function for minidumps which calculates the offset into the carveout region using the start of the physical address instead of the start of the first elf segment.

rpmsg: glink: smem: Wrap driver context

2023-02-14T16:19:38+00:00

The Glink SMEM driver allocates a struct device and hangs two devres-allocated pipe objects thereon. To facilitate the move of interrupt and mailbox handling to the driver, introduce a wrapper object capturing the device, glink reference and remote processor id. The type of the remoteproc reference is updated, as these are specifically targeting the SMEM implementation.

remoteproc: qcom: Add capability to collect minidumps

2020-12-10T19:16:54+00:00

This patch adds support for collecting minidump in the event of remoteproc crash. Parse the minidump table based on remoteproc's unique minidump-id, read all memory regions from the remoteproc's minidump table entry and expose the memory to userspace. The remoteproc platform driver can choose to collect a full/mini dump by specifying the coredump op.

remoteproc: sysmon: Expose the shutdown result

2020-11-26T00:03:30+00:00

A graceful shutdown of the Qualcomm remote processors where traditionally performed by invoking a shared memory state signal and waiting for the associated ack. This was later superseded by the "sysmon" mechanism, where some form of shared memory bus is used to send a "graceful shutdown request" message and one of more signals comes back to indicate its success. But when this newer mechanism is in effect the firmware is shut down by the time the older mechanism, implemented in the remoteproc drivers, attempts to perform a graceful shutdown - and as such it will never receive an ack back. This patch therefor track the success of the latest shutdown attempt in sysmon and exposes a new function in the API that the remoteproc driver can use to query the success and the necessity of invoking the older mechanism.

remoteproc: qcom: Add per subsystem SSR notification

2020-07-09T04:45:03+00:00

Currently there is a single notification chain which is called whenever any remoteproc shuts down. This leads to all the listeners being notified, and is not an optimal design as kernel drivers might only be interested in listening to notifications from a particular remoteproc. Create a global list of remoteproc notification info data structures. This will hold the name and notifier_list information for a particular remoteproc. The API to register for notifications will use name argument to retrieve the notification info data structure and the notifier block will be added to that data structure's notification chain. Also move from blocking notifier to srcu notifer based implementation to support dynamic notifier head creation.
