This adds new macros for saving and restoring checkpointed architected state from and to the thread_struct. It also adds some debugging macros for when your brain explodes trying to debug your transactional memory enabled kernel. Signed-off-by:

Set of new archtected state for saving away on context switch. Signed-off-by:
-
Michael Neuling authored
Here we define the new instructions we need for transactional memory in the kernel. This is so we can support compiling with binutils that don't support the new transactional memory instructions. Transactional memory results in two sets of architected state (GPRs/VSRs etc). treclaim allows us to read the checkpointed state (from the tbegin) so that we can store it away on a context switch. It does this by overwriting the exiting architected state, so you have to save that away before you treclaim. treclaim will also abort a transaction, so you can give a register value which contains an abort reason. trecheckpoint allows us to inject into the checkpointed state as if it were at the tbegin. It does this by copying the current architected state into the checkpointed state. Signed-off-by:

In commit 466921c5 we added a hack to set the paca data_offset to zero so that per-cpu accesses would work on the boot cpu prior to per-cpu areas being setup. This fixed a problem with lockdep touching per-cpu areas very early in boot. However if we combine CONFIG_LOCK_STAT=y with any of the PPC_EARLY_DEBUG options, we can hit the same problem in udbg_early_init(). To avoid that we need to set the data_offset of the boot_paca also. So factor out the fixup logic and call it for both the boot_paca, and "the paca of the boot cpu". Signed-off-by:

Commit a413f474 ("powerpc: Disable relocation on exceptions whenever PR KVM is active") added calls to pSeries_disable_reloc_on_exc() and pSeries_enable_reloc_on_exc() to book3s_pr.c, and added declarations of those functions to <asm/hvcall.h>, but didn't add an include of <asm/hvcall.h> to book3s_pr.c. 64-bit kernels seem to get hvcall.h included via some other path, but 32-bit kernels fail to compile with: arch/powerpc/kvm/book3s_pr.c: In function ‘kvmppc_core_init_vm’: arch/powerpc/kvm/book3s_pr.c:1300:4: error: implicit declaration of function ‘pSeries_disable_reloc_on_exc’ [-Werror=implicit-function-declaration] arch/powerpc/kvm/book3s_pr.c: In function ‘kvmppc_core_destroy_vm’: arch/powerpc/kvm/book3s_pr.c:1316:4: error: implicit declaration of function ‘pSeries_enable_reloc_on_exc’ [-Werror=implicit-function-declaration] cc1: all warnings being treated as errors make[2]: *** [arch/powerpc/kvm/book3s_pr.o] Error 1 make[1]: *** [arch/powerpc/kvm] Error 2 make: *** [sub-make] Error 2 This fixes it by adding an include of hvcall.h.

The CFAR (Come-From Address Register) is a useful debugging aid that exists on POWER7 processors. Currently HV KVM doesn't save or restore the CFAR register for guest vcpus, making the CFAR of limited use in guests. This adds the necessary code to capture the CFAR value saved in the early exception entry code (it has to be saved before any branch is executed), save it in the vcpu.arch struct, and restore it on entry to the guest.

Some of the interrupt vectors on 64-bit POWER server processors are only 32 bytes long, which is not enough for the full first-level interrupt handler. For these we currently just have a branch to an out-of-line handler. However, this means that we corrupt the CFAR (come-from address register) on POWER7 and later processors. To fix this, we split the EXCEPTION_PROLOG_1 macro into two pieces: EXCEPTION_PROLOG_0 contains the part up to the point where the CFAR is saved in the PACA, and EXCEPTION_PROLOG_1 contains the rest. We then put EXCEPTION_PROLOG_0 in the short interrupt vectors before we branch to the out-of-line handler, which contains the rest of the first-level interrupt handler. To facilitate this, we define new _OOL (out of line) variants of STD_EXCEPTION_PSERIES, etc. In order to get EXCEPTION_PROLOG_0 to be short enough, i.e., no more than 6 instructions, it was necessary to move the stores that move the PPR and CFAR values into the PACA into __EXCEPTION_PROLOG_1 and to get rid of one of the two HMT_MEDIUM instructions. Previously there was a HMT_MEDIUM_PPR_DISCARD before the prolog, which was nop'd out on processors with the PPR (POWER7 and later), and then another HMT_MEDIUM inside the HMT_MEDIUM_PPR_SAVE macro call inside __EXCEPTION_PROLOG_1, which was nop'd out on processors without PPR. Now the HMT_MEDIUM inside EXCEPTION_PROLOG_0 is there unconditionally and the HMT_MEDIUM_PPR_DISCARD is not strictly necessary, although this leaves it in for the interrupt vectors where there is room for it. Previously we had a handler for hypervisor maintenance interrupts at 0xe50, which doesn't leave enough room for the vector for hypervisor emulation assist interrupts at 0xe40, since we need 8 instructions. The 0xe50 vector was only used on POWER6, as the HMI vector was moved to 0xe60 on POWER7. Since we don't support running in hypervisor mode on POWER6, we just remove the handler at 0xe50. This also changes denorm_exception_hv to use EXCEPTION_PROLOG_0 instead of open-coding it, and removes the HMT_MEDIUM_PPR_DISCARD from the relocation-on vectors (since any CPU that supports relocation-on interrupts also has the PPR).

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:

Nishanth Aravamudan authored
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.

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 ...
