firmware: qcom: scm: Allow QSEECOM on Yoga Slim 7x Gen11

2026-09-11T03:14:14+00:00

Allow the use of QSEECOM on the Glymur-based Lenovo Yoga Slim 7x Gen11, as there seem to be no issues with the firmware that would mandate disabling it.

firmware: QCOM interfaces should depend on ARCH_QCOM

2026-09-10T14:54:25+00:00

The various Qualcomm firmware interfaces are only present on Qualcomm systems. Hence add dependencies on ARCH_QCOM, to prevent asking the user about them when configuring a kernel without Qualcomm SoC support. Make QCOM_PAS invisible instead, as it is already selected by its users when needed.

treewide: refresh kmalloc_obj() conversions

2026-09-05T04:37:00+00:00

This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

firmware: qcom: scm: Use devm_of_reserved_mem_device_init()

2026-09-03T14:40:30+00:00

Switch from of_reserved_mem_device_init() to the new resource managed devm_of_reserved_mem_device_init() so that the reserved memory region is released automatically on probe failure or device unbind. This eliminates the err_rmem cleanup label and the need to call of_reserved_mem_device_release() explicitly on error paths.

firmware: qcom: scm: Allow QSEECOM on HP EliteBook X G2q 14 AI

2026-08-31T14:56:29+00:00

The HP EliteBook X G2q 14" Next Gen AI PC is a Snapdragon X2 Elite (Glymur) laptop whose firmware exposes EFI variables through QSEECOM. Add its board compatible to the QSEECOM allowlist so that EFI variable access (efivarfs) works on this machine. Without it the kernel reports "qseecom: untested machine, skipping" and efivarfs is empty.

firmware: qcom: scm: Fix tzmem state on probe retry

2026-07-30T21:31:34+00:00

qcom_tzmem_enable() returns -EBUSY if called a second time, but this causes probe retries to fail permanently if a later step in qcom_scm_probe() defers after qcom_tzmem_enable() has already succeeded. Use DO_ONCE() to ensure qcom_tzmem_init() runs exactly once across all calls in a thread-safe manner. qcom_tzmem_dev is set on every call since probe retries use the same device pointer. The result of the first initialisation is cached and returned to every subsequent caller.

firmware: qcom: scm: Fix reserved memory cleanup on probe failure

2026-07-30T21:31:34+00:00

of_reserved_mem_device_init() adds an entry to a global list with no devres counterpart. If qcom_scm_probe() fails after the call the assignment is never cleaned up. A probe retry would add a duplicate entry, leaking the original one permanently. Add an err_rmem label that calls of_reserved_mem_device_release() and route all error paths after of_reserved_mem_device_init() through it. of_reserved_mem_device_release() is safe to call unconditionally as it simply walks an empty list when nothing was assigned.
