Signed-off-by: Andrew Cooper --- CC: Jan Beulich CC: Wei Liu CC: Roger Pau Monn=C3=A9 CC: Juergen Gross CC: Dario Faggioli This patch depends on Dario's series, and cant go in until then. Also RFC. CC: Stefano Stabellini CC: Tamas K Lengyel I tried turning off MEM_ACCESS, but I can't get Kconfig to actually turn it off in the build. What is the deal with MEM_ACCESS_ALWAYS_ON ? It makes it impossible to turn MEM_ACCESS off, becaue it is selected by x86, which leav= es MEM_ACCESS enabled and unmodifiable. --- tools/firmware/xen-dir/Makefile | 2 +- xen/arch/x86/configs/pvshim_defconfig | 5 ++++- 2 files changed, 5 insertions(+), 2 deletions(-) diff --git a/tools/firmware/xen-dir/Makefile b/tools/firmware/xen-dir/Makef= ile index 83597f0017..7435421251 100644 --- a/tools/firmware/xen-dir/Makefile +++ b/tools/firmware/xen-dir/Makefile @@ -41,7 +41,7 @@ linkfarm.stamp: $(DEP_DIRS) $(DEP_FILES) FORCE $(D): linkfarm.stamp $(MAKE) -C $(D)/xen distclean =20 -$(D)/xen/.config: $(D) +$(D)/xen/.config: $(D) $(D)/xen/arch/x86/configs/pvshim_defconfig $(MAKE) -C $(@D) KBUILD_DEFCONFIG=3Dpvshim_defconfig XEN_CONFIG_EXPERT=3D= y defconfig =20 xen-shim: $(D)/xen/.config diff --git a/xen/arch/x86/configs/pvshim_defconfig b/xen/arch/x86/configs/p= vshim_defconfig index 9710aa6238..329aaf9029 100644 --- a/xen/arch/x86/configs/pvshim_defconfig +++ b/xen/arch/x86/configs/pvshim_defconfig @@ -5,6 +5,7 @@ CONFIG_PVH_GUEST=3Dy CONFIG_PV_SHIM=3Dy CONFIG_PV_SHIM_EXCLUSIVE=3Dy CONFIG_NR_CPUS=3D32 +CONFIG_SCHED_NULL=3Dy # Disable features not used by the PV shim # CONFIG_SHADOW_PAGING is not set # CONFIG_BIGMEM is not set @@ -13,10 +14,12 @@ CONFIG_NR_CPUS=3D32 # CONFIG_KEXEC is not set # CONFIG_XENOPROF is not set # CONFIG_XSM is not set +# CONFIG_SCHED_CREDIT is not set # CONFIG_SCHED_CREDIT2 is not set # CONFIG_SCHED_RTDS is not set # CONFIG_SCHED_ARINC653 is not set -# CONFIG_SCHED_NULL is not set # CONFIG_LIVEPATCH is not set # CONFIG_SUPPRESS_DUPLICATE_SYMBOL_WARNINGS is not set # CONFIG_DEBUG is not set +# CONFIG_MEM_ACCESS_ALWAYS_ON is not set +# CONFIG_MEM_ACCESS is not set --=20 2.11.0 _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
