[PATCH v2 2/3] perf/smmuv3: Add a MODULE_SOFTDEP() to indicate dependency on SMMU
From: Zhen Lei <hidden>

Also in:
linux-iommu, lkml
Subsystem:
arm pmu profiling and debugging, the rest · Maintainers:
Will Deacon, Mark Rutland, Linus Torvalds
The MODULE_SOFTDEP() gives user space a hint of the loading sequence. And when command "modprobe arm_smmuv3_pmu" is executed, the arm_smmu_v3.ko is automatically loaded in advance. Signed-off-by: Zhen Lei <redacted> --- drivers/perf/arm_smmuv3_pmu.c | 1 + 1 file changed, 1 insertion(+)
