This patch adds support for enabling and context switching the Target Address Register in Power8. The TAR is a new special purpose register that can be used for computed branches with the bctar[l] (branch conditional to TAR) instruction in the same manner as the count and link registers.

pseries/iommu: remove DDW on kexec We currently insert a property in the device-tree when we successfully configure DDW for a given slot. This was meant to be an optimization to speed up kexec/kdump, so that we don't need to make the RTAS calls again to re-configured DDW in the new kernel. However, we end up tripping a plpar_tce_stuff failure on kexec/kdump because we unconditionally parse the ibm,dma-window property for the node at bus/dev setup time. This property contains the 32-bit DMA window LIOBN, which is distinct from the DDW window's. We pass that LIOBN (via iommu_table_init -> iommu_table_clear -> tce_free -> tce_freemulti_pSeriesLP) to plpar_tce_stuff, which fails because that 32-bit window is no longer present after 25ebc45b ("powerpc/pseries/iommu: remove default window before attempting DDW manipulation"). I believe the simplest, easiest-to-maintain fix is to just change our initcall to, rather than detecting and updating the new kernel's DDW knowledge, just remove all DDW configurations. When the drivers re-initialize, we will set everything back up as it was before. Signed-off-by:

It seems, we're fine with just annotating the two functions.

There are now two kinds of DMA windows that might be presented by PowerVM DDW support -- huge windows (that can map all of system memory regardless of the LPAR configuration) and non-huge windows (which can't). They are implemented slightly differently in PowerVM, and thus have different characteristics. The most obvious is that slot isolate doesn't clear the TCEs/window for us with non-huge windows. Thus, when a DLPAR operation occurs on a slot using a non-huge window, TCEs are still present (the notifier chain doesn't currently remove them explicitly) and the DLPAR fails. Fix this by calling remove_ddw() first, which will unmap the DDW TCEs. Note: a corresponding change to drmgr is needed to actually successfully DLPAR, such that the device-tree update (which causes the notifier chain to fire) occurs before slot isolate. Signed-off-by:

tce_clearrange_multi_pSeriesLP is attempting to iterate over all TCEs in a given range. However, is it not advancing the dma_offset value passed to plpar_tce_stuff via the next value. This prevents DLPAR from completing, because TCEs are still present at slot isolation time. Signed-off-by:

perf/Power: PERF_EVENT_IOC_ENABLE does not reenable event If we disable a perf event because we exceeded the specified ->event_limit, power_pmu_stop() sets the PERF_HES_STOPPED flag on the event. If the application then re-enables the event using PERF_EVENT_IOC_ENABLE ioctl, we don't ever clear this STOPPED flag. Consequently, the user space is never notified of the event. Following message has more background and test case. http://lists.eecs.utk.edu/pipermail/ptools-perfapi/2012-October/002528.html Used the following test cases to verify that this patch works on latest PAPI. $ papi.git/src/ctests/nonthread PAPI_TOT_CYC@5000000 $ papi.git/src/ctests/overflow_single_event Changelog[v2]: - [Paul Mackerras] Also clear PERF_HES_UPTODATE flag since we are restarting the event; cleanup comments and patch description.

CTS-1000 is based on P4080. GPIO 27 is used to signal the FPGA to switch off power, and also associates IRQ 8 with front-panel button press (which we use to call orderly_poweroff()). The relevant device-tree looks like this: gpio0: gpio@130000 { compatible = "fsl,qoriq-gpio"; reg = <0x130000 0x1000>; interrupts = <55 2 0 0>; #gpio-cells = <2>; gpio-controller; /* Allows powering off the system via GPIO signal. */ gpio-halt@27 { compatible = "sgy,gpio-halt"; gpios = <&gpio0 27 0>; interrupts = <8 1 0 0>; }; }; Because the driver cannot match on sgy,gpio-halt (because the node is never processed through of_platform), it matches on fsl,qoriq-gpio and then checks child nodes for the matching sgy,gpio-halt. This also ensures that the GPIO controller is detected prior to sgy_cts1000's probe callback, since that node wont match via of_platform until the controller is registered. Also, because the GPIO handler for triggering system poweroff might sleep, the IRQ uses a workqueue to call orderly_poweroff(). As a final note, this driver may be expanded for other features specific to the CTS-1000.

With lazy interrupt, we always call __check_irq_replaysome with decrementers_next_tb to check if we need to replay timer interrupt. So in hotplug case we also need to set decrementers_next_tb as MAX to make sure __check_irq_replay don't replay timer interrupt when return as we expect, otherwise we'll trap here infinitely.

commit f96972f2 "kernel/sys.c: call disable_nonboot_cpus() in kernel_restart()" added a call to disable_nonboot_cpus() on kernel_restart(), which tries to shutdown all the CPUs except the first one. The issue with the PA Semi, is that it does not support CPU hotplug. When the call is made to __cpu_down(), it calls the notifiers CPU_DOWN_PREPARE, and then tries to take the CPU down. One of the notifiers to the CPU hotplug code, is the cpufreq. The DOWN_PREPARE will call __cpufreq_remove_dev() which calls cpufreq_driver->exit. The PA Semi exit handler unmaps regions of I/O that is used by an interrupt that goes off constantly (system_reset_common, but it goes off during normal system operations too). I'm not sure exactly what this interrupt does. Running a simple function trace, you can see it goes off quite a bit: # tracer: function # # TASK-PID CPU# TIMESTAMP FUNCTION # | | | | | <idle>-0 [001] 1558.859363: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.860112: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.861109: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [001] 1558.861361: .pasemi_system_reset_exception <-.system_reset_exception <idle>-0 [000] 1558.861437: .pasemi_system_reset_exception <-.system_reset_exception When the region is unmapped, the system crashes with: Disabling non-boot CPUs ...

The IOMMU may stop processing page translations due to a perceived lack of credits for writing upstream peripheral page service request (PPR) or event logs. If the L2B miscellaneous clock gating feature is enabled the IOMMU does not properly register credits after the log request has completed, leading to a potential system hang. BIOSes are supposed to disable L2B micellaneous clock gating by setting L2_L2B_CK_GATE_CONTROL[CKGateL2BMiscDisable](D0F2xF4_x90[2]) = 1b. This patch corrects that for those which do not enable this workaround. Signed-off-by:

dm9620 is a newer variant of dm9601 with more features (usb 2.0, checksum offload, ..), but it can also be put in a dm9601 compatible mode, allowing us to reuse the existing driver. This does mean that the extended features like checksum offload cannot be used, but that's hardly critical on a 100mbps interface.

While sctp handling a duplicate COOKIE-ECHO and the action is 'Association restart', sctp_sf_do_dupcook_a() will processing the unexpected COOKIE-ECHO for peer restart, but it does not set the association state to SCTP_STATE_ESTABLISHED, so the association could stuck in SCTP_STATE_SHUTDOWN_PENDING state forever. This violates the sctp specification: RFC 4960 5.2.4. Handle a COOKIE ECHO when a TCB Exists Action A) In this case, the peer may have restarted. ..... After this, the endpoint shall enter the ESTABLISHED state. To resolve this problem, adding a SCTP_CMD_NEW_STATE cmd to the command list before SCTP_CMD_REPLY cmd, this will set the restart association to SCTP_STATE_ESTABLISHED state properly and also avoid I-bit being set in the DATA chunk header when COOKIE_ACK is bundled with DATA chunks.

We did this for IPv4 in b49d3c1e "net: ipmr: limit MRT_TABLE identifiers" but we need to do it for IPv6 as well. On IPv6 the name is "pim6reg" instead of "pimreg" so there is one less digit allowed. The strcpy() is in ip6mr_reg_vif(). Signed-off-by:

commit 9992c2e2 (net: cdc_ncm: workaround for missing CDC Union) added code to lookup an IAD for the interface we are probing. This is redundant. The USB core has already done the lookup and saved the result in the USB interface struct. Use that instead.

We never want multicast MAC addresses in the Distributed ARP Table, so it's best to completely ignore ARP packets containing them where we expect unicast addresses. Signed-off-by:
