由 Gautham R. Shenoy 提交于
Currently we use the stop-api provided by the firmware to program the SLW engine to restore the values of hypervisor resources that get lost on deeper idle states (such as winkle). Since the deep states were only used for CPU-Hotplug on POWER8 systems, we would program the LPCR to have the PECE1 bit since Hotplugged CPUs shouldn't be spuriously woken up by decrementer. On POWER9, some of the deep platform idle states such as stop4 can be used in cpuidle as well. In this case, we want the CPU in stop4 to be woken up by the decrementer when some timer on the CPU expires. In this patch, we program the stop-api for LPCR with PECE1 bit cleared only when we are offlining the CPU and set it back once the CPU is online. Signed-off-by: NGautham R.

由 Gautham R. Shenoy 提交于
The stop4 idle state on POWER9 is a deep idle state which loses hypervisor resources, but whose latency is low enough that it can be exposed via cpuidle. Until now, the deep idle states which lose hypervisor resources (eg: winkle) were only exposed via CPU-Hotplug. Hence currently on wakeup from such states, barring a few SPRs which need to be restored to their older value, rest of the SPRS are reinitialized to their values corresponding to that at boot time. When stop4 is used in the context of cpuidle, we want these additional SPRs to be restored to their older value, to ensure that the context on the CPU coming back from idle is same as it was before going idle. In this patch, we define a SPR save area in PACA (since we have used up the volatile register space in the stack) and on POWER9, we restore SPRN_PID, SPRN_LDBAR, SPRN_FSCR, SPRN_HFSCR, SPRN_MMCRA, SPRN_MMCR1, SPRN_MMCR2 to the values they had before entering stop.

For debugging very early boot problems we have CONFIG_PPC_EARLY_DEBUG, which allows configuring the kernel such that it unconditionally writes to a particular type of console, regardless of whether that console exists or not. This is useful sometimes when the kernel crashes before it can even determine what platform it's on, and therefore what consoles exist. However if you boot a kernel built this way on a different platform, it will generally crash because it writes to a console that doesn't exist. A particularly nasty instance of this is if you enable the hypervisor console early debug, and then boot that kernel on bare metal. The result is that the kernel calls "the hypervisor" very early in boot, but the kernel *is* the hypervisor, so we jump to the system call handler and start executing all sorts of code that isn't ready to be run. This may lead to a machine check or check stop depending on how lucky you are. Luckily there is an easy way to avoid this particular case. We simply read the MSR before installing the hooks, and if we see MSR_HV is set then we are the hypervisor and we definitely should not use the hypervisor console.

New header file created to contain the data structures and macros needed for In-Memory Collection (IMC) counter pmu devices. The device tree for IMC counters starts at the node "imc-counters". This node contains all the IMC PMU nodes and event nodes for these IMC PMUs. Device probe() parses the device to locate three possible IMC device types (Nest/Core/Thread). Function then branch to parse each unit nodes to populate vital information such as device memory sizes, event nodes information, base address for reserve memory access (if any) and so on.

External IRQ0 (index 48) has the same capabilities as the other IRQ1-7 and is handled by the same register IPIC_SEPNR. When this register is not specified for "ack" in "ipic_info", you cannot configure this IRQ as IRQ_TYPE_EDGE_FALLING. This oversight was probably due to the non-contiguous hwirq numbering of IRQ0 in the IPIC.

Prepping for scripting the MAINTAINERS file cleanup (and possible split) showed a couple of cases where the headers for a couple of entries were bogus. There's a few different kinds of bogosities: - the X-GENE SOC EDAC case was confused and split over two lines - there were four entries for "GREYBUS PROTOCOLS DRIVERS" that were all different things. - the NOKIA N900 CAMERA SUPPORT" was duplicated all of which were more obvious when you started doing associative arrays in perl to track these things by the header (so that we can alphabetize this thing properly, and so that we might split it up by the data too).

When setting up the Xenstore watch for the memory target size the new watch will fire at once. Don't try to reach the configured target size by onlining new memory in this case, as the current memory size will be smaller in almost all cases due to e.g. BIOS reserved pages. Onlining new memory will lead to more problems e.g. undesired conflicts with NVMe devices meant to be operated as block devices. Instead remember the difference between target size and current size when the watch fires for the first time and apply it to any further size changes, too. In order to avoid races between balloon.c and xen-balloon.c init calls do the xen-balloon.c initialization from balloon.c.

Pull powerpc fixes from Michael Ellerman: "A handful of fixes, mostly for new code: - some reworking of the new STRICT_KERNEL_RWX support to make sure we also remove executable permission from __init memory before it's freed. - a fix to some recent optimisations to the hypercall entry where we were clobbering r12, this was breaking nested guests (PR KVM). - a fix for the recent patch to opal_configure_cores(). This could break booting on bare metal Power8 boxes if the kernel was built without CONFIG_JUMP_LABEL_FEATURE_CHECK_DEBUG. - .. and finally a workaround for spurious PMU interrupts on Power9 DD2. Thanks to: Nicholas Piggin, Anton Blanchard, Balbir Singh" * tag 'powerpc-4.13-3' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/mm: Mark __init memory no-execute when STRICT_KERNEL_RWX=y powerpc/mm/hash: Refactor hash__mark_rodata_ro() powerpc/mm/radix: Refactor radix__mark_rodata_ro() powerpc/64s: Fix hypercall entry clobbering r12 input powerpc/perf: Avoid spurious PMU interrupts after idle powerpc/powernv: Fix boot on Power8 bare metal due to opal_configure_cores()

Pull x86 fixes from Ingo Molnar: "Half of the fixes are for various build time warnings triggered by randconfig builds. Most (but not all...) were harmless. There's also: - ACPI boundary condition fixes - UV platform fixes - defconfig updates - an AMD K6 CPU init fix - a %pOF printk format related preparatory change - .. and a warning fix related to the tlb/PCID changes" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/devicetree: Convert to using %pOF instead of ->full_name x86/platform/uv/BAU: Disable BAU on single hub configurations x86/platform/intel-mid: Fix a format string overflow warning x86/platform: Add PCI dependency for PUNIT_ATOM_DEBUG x86/build: Silence the build with "make -s" x86/io: Add "memory" clobber to insb/insw/insl/outsb/outsw/outsl x86/fpu/math-emu: Avoid bogus -Wint-in-bool-context warning x86/fpu/math-emu: Fix possible uninitialized variable use perf/x86: Shut up false-positive -Wmaybe-uninitialized warning x86/defconfig: Remove stale, old Kconfig options x86/ioapic: Pass the correct data to unmask_ioapic_irq() x86/acpi: Prevent out of bound access caused by broken ACPI tables x86/mm, KVM: Fix warning when !CONFIG_PREEMPT_COUNT x86/platform/uv/BAU: Fix congested_response_us not taking effect x86/cpu: Use indirect call to measure performance in init_amd_k6()
