I’ve put it in arch because it’s only modified by the arm code, but if you think it’s ok to have it in struct xen_domctl_createdomain, I don’t see any problem. My knowledge of the tool stack is limited so I didn’t know about the advantages of that change. Cheers, Luca > > > Juergen > <OpenPGP_0xB0DE9DD628BF132F.asc>

If so, I think we can avoid it. Instead, we could: - generate the cpupool-id in xen/arch/arm/cpupool.c - keep track of cpupool-id <--> "cpupool name", where "cpupool name" is the node name in device tree (sibling node names are unique in device tree). (Alternatively we could use the phandle.) We could have a __initdata pool_names_map to convert cpupool names to cpupool-ids. - here retrieve the cpupool_id from the cpupool node name > /* > * The variable max_init_domid is initialized with zero, so here it's > * very important to use the pre-increment operator to call > diff --git a/xen/arch/x86/domain.c b/xen/arch/x86/domain.c > index ef1812dc1402..3e3cf88c9c82 100644 > --- a/xen/arch/x86/domain.c > +++ b/xen/arch/x86/domain.c > @@ -880,6 +880,12 @@ int arch_domain_create(struct domain *d, > return rc; > } > > +unsigned int > +arch_get_domain_cpupool_id(const struct xen_domctl_createdomain *config) > +{ > + return 0; > +} > + > void arch_domain_destroy(struct domain *d) > { > if ( is_hvm_domain(d) ) > diff --git a/xen/common/domain.c b/xen/common/domain.c > index 2048ebad86ff..d42ca8292025 100644 > --- a/xen/common/domain.c > +++ b/xen/common/domain.c > @@ -665,6 +665,8 @@ struct domain *domain_create(domid_t domid, > > if ( !is_idle_domain(d) ) > { > + unsigned int domain_cpupool_id; > + > watchdog_domain_init(d); > init_status |= INIT_watchdog; > > @@ -698,7 +700,8 @@ struct domain *domain_create(domid_t domid, > if ( !d->pbuf ) > goto fail; > > - if ( (err = sched_init_domain(d, 0)) != 0 ) > + domain_cpupool_id = arch_get_domain_cpupool_id(config); > + if ( (err = sched_init_domain(d, domain_cpupool_id)) != 0 ) > goto fail; > > if ( (err = late_hwdom_init(d)) != 0 ) > diff --git a/xen/include/public/arch-arm.h b/xen/include/public/arch-arm.h > index 94b31511ddea..2c5d1ea7f01a 100644 > --- a/xen/include/public/arch-arm.h > +++ b/xen/include/public/arch-arm.h > @@ -321,6 +321,8 @@ struct xen_arch_domainconfig { > uint16_t tee_type; > /* IN */ > uint32_t nr_spis; > + /* IN */ > + unsigned int cpupool_id; > /* > * OUT > * Based on the property clock-frequency in the DT timer node. > diff --git a/xen/include/public/domctl.h b/xen/include/public/domctl.h > index b85e6170b0aa..31ec083cb06e 100644 > --- a/xen/include/public/domctl.h > +++ b/xen/include/public/domctl.h > @@ -38,7 +38,7 @@ > #include "hvm/save.h" > #include "memory.h" > > -#define XEN_DOMCTL_INTERFACE_VERSION 0x00000014 > +#define XEN_DOMCTL_INTERFACE_VERSION 0x00000015 > > /* > * NB. xen_domctl.domain is an IN/OUT parameter for this operation. > diff --git a/xen/include/xen/domain.h b/xen/include/xen/domain.h > index 160c8dbdab33..fb018871bc17 100644 > --- a/xen/include/xen/domain.h > +++ b/xen/include/xen/domain.h > @@ -63,6 +63,9 @@ void unmap_vcpu_info(struct vcpu *v); > int arch_domain_create(struct domain *d, > struct xen_domctl_createdomain *config); > > +unsigned int > +arch_get_domain_cpupool_id(const struct xen_domctl_createdomain *config); > + > void arch_domain_destroy(struct domain *d); > > void arch_domain_shutdown(struct domain *d); > -- > 2.17.1 >
