This may not be a desirable since # "perf" API is the primary interface to program PMU and # collect counter data in the system. But that said, we # cant remove these sysfs files since we dont whether # anyone/anything is using them. # # So the patch adds a new CONFIG option 'CONFIG_PMU_SYSFS' # (user selectable) to be used in sysfs file creation for # PMU SPRs. New option by default is disabled, but can be # enabled if user needs it. # # Tested this patch behaviour in powernv and pseries machines. # Patch is also tested for pmac32_defconfig. # # Signed-off-by: Kajol Jain # Tested-by: Nageswara R Sastry # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20200214080606.26872-2-kjain@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 7f08c318df48fbcfc16a1cfbfad6818542510d57 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc5200_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- mpc5200_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc5200_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:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:72:12: 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/fs/ext4/extents.c: In function 'ext4_convert_unwritten_io_end_vec': /kisskb/src/fs/ext4/extents.c:5009:23: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2598:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/gpu/drm/drm_dp_mst_topology.c: In function 'drm_dp_mst_dsc_aux_for_port': /kisskb/src/drivers/gpu/drm/drm_dp_mst_topology.c:5400:9: warning: missing braces around initializer [-Wmissing-braces] /kisskb/src/drivers/gpu/drm/drm_dp_mst_topology.c:5400:9: warning: (near initialization for 'desc.ident') [-Wmissing-braces] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1859:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /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/fs/io_uring.c: In function '__io_sqe_files_update.isra.81': /kisskb/src/fs/io_uring.c:5824:13: warning: 'err' may be used uninitialized in this function [-Wuninitialized] INFO: Uncompressed kernel (size 0x6bf150) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x6bf150) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x6bf150) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x6aeb04) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) Image Name: Linux-5.6.0-rc2-g7f08c318df48 Created: Thu Feb 20 02:54:33 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3363504 Bytes = 3284.67 KiB = 3.21 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.6.0-rc2-g7f08c318df48 Created: Thu Feb 20 02:54:34 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3393118 Bytes = 3313.59 KiB = 3.24 MiB Load Address: 00700000 Entry Point: 00700278 Image Name: Linux-5.6.0-rc2-g7f08c318df48 Created: Thu Feb 20 02:54:34 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3393443 Bytes = 3313.91 KiB = 3.24 MiB Load Address: 00700000 Entry Point: 00700278 Image Name: Linux-5.6.0-rc2-g7f08c318df48 Created: Thu Feb 20 02:54:34 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3393543 Bytes = 3314.01 KiB = 3.24 MiB Load Address: 00700000 Entry Point: 00700278 Completed OK # rm -rf /kisskb/build/powerpc-next_mpc5200_defconfig_powerpc-gcc4.6 # Build took: 0:01:11.828104
