With more and more CDF_xxx internal flags in and to save the space, this commit introduces a new field "flags" in struct domain to store CDF_* internal flags directly.
Another new CDF_xxx will be introduced in the next patch. Signed-off-by: Penny Zheng <penny.zh...@arm.com> --- v2 changes: - let "flags" live in the struct domain. So other arch can take advantage of it in the future - fix coding style --- xen/arch/arm/domain.c | 2 -- xen/arch/arm/include/asm/domain.h | 3 +-- xen/common/domain.c | 3 +++ xen/include/xen/sched.h | 3 +++ 4 files changed, 7 insertions(+), 4 deletions(-) diff --git a/xen/arch/arm/domain.c b/xen/arch/arm/domain.c index 8110c1df86..74189d9878 100644 --- a/xen/arch/arm/domain.c +++ b/xen/arch/arm/domain.c @@ -709,8 +709,6 @@ int arch_domain_create(struct domain *d, ioreq_domain_init(d); #endif - d->arch.directmap = flags & CDF_directmap; - /* p2m_init relies on some value initialized by the IOMMU subsystem */ if ( (rc = iommu_domain_init(d, config->iommu_opts)) != 0 ) goto fail; diff --git a/xen/arch/arm/include/asm/domain.h b/xen/arch/arm/include/asm/domain.h index ed63c2b6f9..36ec00e62d 100644 --- a/xen/arch/arm/include/asm/domain.h +++ b/xen/arch/arm/include/asm/domain.h @@ -29,7 +29,7 @@ enum domain_type { #define is_64bit_domain(d) (0) #endif -#define is_domain_direct_mapped(d) (d)->arch.directmap +#define is_domain_direct_mapped(d) ((d)->flags & CDF_directmap) /* * Is the domain using the host memory layout? @@ -103,7 +103,6 @@ struct arch_domain void *tee; #endif - bool directmap; } __cacheline_aligned; struct arch_vcpu diff --git a/xen/common/domain.c b/xen/common/domain.c index 351029f8b2..859cc13d3b 100644 --- a/xen/common/domain.c +++ b/xen/common/domain.c @@ -568,6 +568,9 @@ struct domain *domain_create(domid_t domid, /* Sort out our idea of is_system_domain(). */ d->domain_id = domid; + /* Holding CDF_* internal flags. */ + d->flags = flags; + /* Debug sanity. */ ASSERT(is_system_domain(d) ? config == NULL : config != NULL); diff --git a/xen/include/xen/sched.h b/xen/include/xen/sched.h index ed8539f6d2..68eb08058e 100644 --- a/xen/include/xen/sched.h +++ b/xen/include/xen/sched.h @@ -591,6 +591,9 @@ struct domain struct ioreq_server *server[MAX_NR_IOREQ_SERVERS]; } ioreq_server; #endif + + /* Holding CDF_* constant.
