The parameters are now iommu-indexes and not device-ids anymore. You should reflect that in the prototypes here too. > diff --git a/drivers/iommu/amd_iommu_proto.h b/drivers/iommu/amd_iommu_proto.h > index 7eb60c1..1f10b3f 100644 > --- a/drivers/iommu/amd_iommu_proto.h > +++ b/drivers/iommu/amd_iommu_proto.h > @@ -58,8 +58,8 @@ extern int amd_iommu_domain_set_gcr3(struct iommu_domain > *dom, int pasid, > > /* IOMMU Performance Counter functions */ > extern bool amd_iommu_pc_supported(void); > -extern u8 amd_iommu_pc_get_max_banks(u16 devid); > -extern u8 amd_iommu_pc_get_max_counters(u16 devid); > +extern u8 amd_iommu_pc_get_max_banks(uint devid); > +extern u8 amd_iommu_pc_get_max_counters(uint devid); Same here, and why do you need to declare the prototypes in two different header files?
