We do this so # when we get an EEH event and everything gets reset that we can restore # them. # # Unfortunately we save this state before we've enabled the MMIO space # on the bridges. Hence if we have to reset the bridge when we come back # MMIO is not enabled and we end up taking an PE freeze when the driver # starts accessing again. # # This patch forces the memory/MMIO and bus mastering on when restoring # bridges on EEH. Ideally we'd do this correctly by saving the # configuration space writes later, but that will have to come later in # a larger EEH rewrite. For now we have this simple fix. # # The original bug can be triggered on a boston machine by doing: # echo 0x8000000000000000 > /sys/kernel/debug/powerpc/PCI0001/err_injct_outbound # On boston, this PHB has a PCIe switch on it. Without this patch, # you'll see two EEH events, 1 expected and 1 the failure we are fixing # here. The second EEH event causes the anything under the PHB to # disappear (i.e. the i40e eth). # # With this patch, only 1 EEH event occurs and devices properly recover. # # Fixes: 652defed4875 ("powerpc/eeh: Check PCIe link after reset") # Cc: stable@vger.kernel.org # v3.11+ # Reported-by: Pridhiviraj Paidipeddi <ppaidipe@linux.vnet.ibm.com> # Signed-off-by: Michael Neuling <mikey@neuling.org> # Acked-by: Russell Currey <ruscur@russell.cc> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 13a83eac373c49c0a081cbcd137e79210fe78acd # < make -s -j 20 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_redwood_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/redwood_defconfig # make -s -j 20 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_redwood_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_44x_redwood_defconfig_powerpc-5.3 # Build took: 0:00:49.414627
