Since we don't specify a logical memory # address for bind hcall, we can use the H_SCM_QUERY hcall to query # the already bound logical address. # # Boot time difference with and without patch is: # # [ 5.583617] IOMMU table initialized, virtual merging enabled # [ 5.603041] papr_scm ibm,persistent-memory:ibm,pmemory@44104001: Retrying bind after unbinding # [ 301.514221] papr_scm ibm,persistent-memory:ibm,pmemory@44108001: Retrying bind after unbinding # [ 340.057238] hv-24x7: read 1530 catalog entries, created 537 event attrs (0 failures), 275 descs # # after fix # # [ 5.101572] IOMMU table initialized, virtual merging enabled # [ 5.116984] papr_scm ibm,persistent-memory:ibm,pmemory@44104001: Querying SCM details # [ 5.117223] papr_scm ibm,persistent-memory:ibm,pmemory@44108001: Querying SCM details # [ 5.120530] hv-24x7: read 1530 catalog entries, created 537 event attrs (0 failures), 275 descs # # Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20190903123452.28620-2-aneesh.kumar@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 b6a4fec7d708dcc769f908ce7b308a0de8b3ad8f # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_g5_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- g5_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_g5_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_g5_defconfig_powerpc-gcc5 # Build took: 0:01:01.608455
