This hcall is handled in the host in # kvmppc_h_set_dawr() which can be called in either real mode on the # guest exit path from hcall_try_real_mode() in book3s_hv_rmhandlers.S, # or in virtual mode when called from kvmppc_pseries_do_hcall() in # book3s_hv.c. # # The function kvmppc_h_set_dawr() updates the dawr and dawrx fields in # the vcpu struct accordingly and then also writes the respective values # into the DAWR and DAWRX registers directly. It is necessary to write # the registers directly here when calling the function in real mode # since the path to re-enter the guest won't do this. However when in # virtual mode the host DAWR and DAWRX values have already been # restored, and so writing the registers would overwrite these. # Additionally there is no reason to write the guest values here as # these will be read from the vcpu struct and written to the registers # appropriately the next time the vcpu is run. # # This also avoids the case when handling h_set_dawr for a nested guest # where the guest hypervisor isn't able to write the DAWR and DAWRX # registers directly and must rely on the real hypervisor to do this for # it when it calls H_ENTER_NESTED. # # Fixes: c1fe190c0672 ("powerpc: Add force enable of DAWR on P9 option") # Signed-off-by: Suraj Jitindar Singh <sjitindarsingh@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 84b028243ef07a3f65c1857343ada2b1022f8bed # < make -s -j 48 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- defconfig # make -s -j 48 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- arch/s390/../../virt/kvm/kvm_main.o: In function `kvm_vcpu_unmap': /kisskb/src/arch/s390/kvm/../../../virt/kvm/kvm_main.c:1799: undefined reference to `memunmap' make[1]: *** [/kisskb/src/Makefile:1052: vmlinux] Error 1 make: *** [Makefile:179: sub-make] Error 2 Command 'make -s -j 48 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc8 # Build took: 0:01:39.151550
