Introduce an exclusive buffer per cpu to hold # faulty SLB entries. In real mode mce handler saves the old SLB contents # into this buffer accessible through paca and print it out later in virtual # mode. # # With this patch the console will log SLB contents like below on SLB MCE # errors: # # [ 507.297236] SLB contents of cpu 0x1 # [ 507.297237] Last SLB entry inserted at slot 16 # [ 507.297238] 00 c000000008000000 400ea1b217000500 # [ 507.297239] 1T ESID= c00000 VSID= ea1b217 LLP:100 # [ 507.297240] 01 d000000008000000 400d43642f000510 # [ 507.297242] 1T ESID= d00000 VSID= d43642f LLP:110 # [ 507.297243] 11 f000000008000000 400a86c85f000500 # [ 507.297244] 1T ESID= f00000 VSID= a86c85f LLP:100 # [ 507.297245] 12 00007f0008000000 4008119624000d90 # [ 507.297246] 1T ESID= 7f VSID= 8119624 LLP:110 # [ 507.297247] 13 0000000018000000 00092885f5150d90 # [ 507.297247] 256M ESID= 1 VSID= 92885f5150 LLP:110 # [ 507.297248] 14 0000010008000000 4009e7cb50000d90 # [ 507.297249] 1T ESID= 1 VSID= 9e7cb50 LLP:110 # [ 507.297250] 15 d000000008000000 400d43642f000510 # [ 507.297251] 1T ESID= d00000 VSID= d43642f LLP:110 # [ 507.297252] 16 d000000008000000 400d43642f000510 # [ 507.297253] 1T ESID= d00000 VSID= d43642f LLP:110 # [ 507.297253] ---------------------------------- # [ 507.297254] SLB cache ptr value = 3 # [ 507.297254] Valid SLB cache entries: # [ 507.297255] 00 EA[0-35]= 7f000 # [ 507.297256] 01 EA[0-35]= 1 # [ 507.297257] 02 EA[0-35]= 1000 # [ 507.297257] Rest of SLB cache entries: # [ 507.297258] 03 EA[0-35]= 7f000 # [ 507.297258] 04 EA[0-35]= 1 # [ 507.297259] 05 EA[0-35]= 1000 # [ 507.297260] 06 EA[0-35]= 12 # [ 507.297260] 07 EA[0-35]= 7f000 # # Suggested-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> # Suggested-by: Michael Ellerman <mpe@ellerman.id.au> # Signed-off-by: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com> # Reviewed-by: Nicholas Piggin <npiggin@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 e310e405015f48d18684d89aa27f8c7536b51268 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_powerpc-allyesconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- allyesconfig # Added to kconfig CONFIG_PROFILE_ALL_BRANCHES=n # Added to kconfig CONFIG_ENABLE_WARN_DEPRECATED=n # Added to kconfig CONFIG_ENABLE_MUST_CHECK=n # Added to kconfig CONFIG_DEBUG_INFO=n # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # yes \n \| make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_powerpc-allyesconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_powerpc-allyesconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/net/Makefile:24: CC cannot link executables.
