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/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 b6a4fec7d708dcc769f908ce7b308a0de8b3ad8f # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_currituck_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 44x/currituck_defconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_currituck_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:194:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:140:32: warning: 'levelspread[<Ue000>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:88:6: note: 'levelspread[<Ue000>]' was declared here /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:338:21: note: 'pdeo' was declared here /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2591:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1852:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:248:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:228:19: note: 'i' was declared here /kisskb/src/drivers/usb/core/devio.c: In function 'async_completed': /kisskb/src/drivers/usb/core/devio.c:625:23: warning: 'errno' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/powerpc/boot/dts/currituck.dts:125.28-161.5: Warning (pci_bridge): /plb/pciex@10100000000: node name is not "pci" or "pcie" /kisskb/src/arch/powerpc/boot/dts/currituck.dts:163.28-198.5: Warning (pci_bridge): /plb/pciex@30100000000: node name is not "pci" or "pcie" /kisskb/src/arch/powerpc/boot/dts/currituck.dts:200.28-235.5: Warning (pci_bridge): /plb/pciex@38100000000: node name is not "pci" or "pcie" arch/powerpc/boot/dts/currituck.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' Completed OK # rm -rf /kisskb/build/powerpc-fixes_44x_currituck_defconfig_powerpc-gcc4.6 # Build took: 0:02:13.339059
