remoteproc: qcom: pas: Guard dtb metadata release with dtb_pas_id check

2026-09-11T09:51:25+00:00

[ Upstream commit c06c5ab4945392d2c2aded6d832ab6b58cabe351 ] All other call sites of qcom_scm_pas_metadata_release() for the DTB context are guarded by a check on pas->dtb_pas_id, but the call inside qcom_pas_load() was not. Fix this by moving the call to the guarded block.

remoteproc: scp: Fix device reference leak on failed lookup

2026-09-07T15:37:05+00:00

commit 22f9efb3ae07f966a1901d929d16df1388cce65c upstream. Make sure to drop the reference taken to the SCP device when attempting to look up its driver data before the driver has been bound. Note that holding a reference to a device does not prevent its driver data from going away.

remoteproc: qcom: Unify user-visible "Qualcomm" name

Various names for Qualcomm as a company are used in user-visible config options: QCOM, Qualcomm and Qualcomm Technologies. Switch to unified "Qualcomm" so it will be easier for users to identify the options when for example running menuconfig.

remoteproc: qcom: Fix leak when custom dump_segments addition fails

Free allocated minidump_region 'name' in qcom_add_minidump_segments() when failing before adding the region to 'dump_segments'. Otherwise, the 'name' is not tracked and is never freed by qcom_minidump_cleanup(). Return error when adding to 'dump_segments' fails.

remoteproc: qcom_q6v5_wcss: drop redundant wcss_q6_bcr_reset

2026-06-09T02:41:59+00:00

The wcss_q6_bcr_reset used on QCS404, and wcss_q6_reset used on IPQ are the same. "BCR reset" is redundant, and likely a mistake. Use the documented "wcss_q6_reset" instead. Drop ".wcss_q6_reset_required" from the descriptor, since all targets now need it. This changes the bindings expectations, however, it actually fixes the driver to consume the intended ones (qcom,q6v5.txt), which lists "wcss_q6_reset" and *not* "wcss_q6_bcr_reset" Fixes: 0af65b9b915e ("remoteproc: qcom: wcss: Add non pas wcss Q6 support for QCS404") Reviewed-by: Konrad Dybcio Signed-off-by: Alexandru Gagniuc Link: https://lore.kernel.org/r/20251208223315.3540680-1-mr.nuke.me@gmail.com Signed-off-by: Bjorn Andersson

remoteproc: xlnx: Enable auto boot feature

2026-05-29T15:02:33+00:00

The remoteproc framework has capability to start (or attach to) the remote processor automatically if auto boot flag is set by the driver during probe. If the 'firmware-name' property is available for the remoteproc node, then that firmware will be loaded and started during auto boot. If the remote core is started by the bootloader then during auto-boot remoteproc framework will try to attach to the remote processor. The current architecture allocates and adds the remoteproc instance before all the hardware such as sram, mbox, TCM is initialized. This design has to be changed for auto boot to work. So, rename zynqmp_r5_rproc_add() function to zynqmp_r5_rproc_alloc() and move adding the remoteproc instance at the end of cluster initialization. This makes sure that all the required hardware is initialized before starting the remote processor.
