Merge tag 'rproc-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

2026-04-17T21:16:15+00:00

Pull remoteproc updates from Bjorn Andersson: - Move requesting of IRQs in TI Keystone driver to probe time instead of remoteproc start, to allow better handling of errors. - Introduce support for more than 10 entries in the Qualcomm minidump implementation. - Add audio DSP remoteproc support for the Qualcomm Eliza platform. Add modem remoteproc support for the Qualcomm MDM9607, MSM8917, MSM8937, and MSM8940 platforms. - Add list of Qualcomm QMI service ids to the QMI header file, in order to avoid sprinkling them across the various drivers using them. Migrate sysmon to use this constant. - Fix several issues related to DeviceTree parsing and mailbox handling in the Xilinx R5F remote processor driver. - Fix incorrect error checks in reserved memory handling and polish the code across i.MX and TI drivers. * tag 'rproc-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: (35 commits) remoteproc: qcom: pas: Add Eliza ADSP support dt-bindings: remoteproc: qcom,milos-pas: Document Eliza ADSP remoteproc: qcom: Add missing space before closing bracket dt-bindings: remoteproc: qcom: Drop types for firmware-name remoteproc: qcom: Fix minidump out-of-bounds access on subsystems array dt-bindings: remoteproc: k3-r5f: Add memory-region-names dt-bindings: remoteproc: k3-r5f: Split up memory regions remoteproc: use SIZE_MAX in rproc_u64_fit_in_size_t() dt-bindings: remoteproc: qcom,sm8550-pas: Add Glymur CDSP dt-bindings: remoteproc: qcom,sm8550-pas: Add Glymur ADSP remoteproc: xlnx: Release mailbox channels on shutdown remoteproc: sysmon: Use the unified QMI service ID instead of defining it locally remoteproc: xlnx: Only access buffer information if IPI is buffered remoteproc: xlnx: Avoid mailbox setup remoteproc: keystone: Request IRQs in probe() remoteproc: pru: Remove empty remove callback remoteproc: pru: Use rproc_of_parse_firmware() to get firmware name remoteproc: da8xx: Reorder resource fetching in probe() remoteproc: da8xx: Remove unused local struct data remoteproc: da8xx: Use dev_err_probe() ...

remoteproc: sysmon: Use the unified QMI service ID instead of defining it locally

2026-03-16T02:05:45+00:00

Instead of defining a local macro with a custom name for the QMI service identifier, use the one provided in qmi.h and remove the locally defined macro.

remoteproc: sysmon: Correct subsys_name_len type in QMI request

2026-03-04T19:12:06+00:00

The QMI message encoder has up until recently read a single byte (as elem_size == 1), but with the introduction of big endian support it's become apparent that this field is expected to be a full u32 - regardless of the size of the length in the encoded message (which is what elem_size specifies). The result is that the encoder now reads past the length byte and rejects the unreasonably large length formed when including the following 3 bytes from the subsys_name array. Fix this by changing to the expected type.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

remoteproc: sysmon: Update qcom_add_sysmon_subdev() comment

The comment says the qcom_add_sysmon_subdev() returns NULL on error but it actually returns error pointers. Signed-off-by: Dan Carpenter Reviewed-by: Dmitry Baryshkov Link: https://lore.kernel.org/r/77a6b65b-5f3f-4a21-a837-7a4a7e09b099@stanley.mountain Signed-off-by: Bjorn Andersson

remoteproc: Explicitly include correct DT includes

2023-07-15T17:35:50+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.
