    When we have VMAP stack, exception prolog 1 sets r1, not r11.

    When it is not an RTAS machine check, don't trash r1 because it is
    needed by prolog 1.

  • commit 3ce47d95b7346dcafd9bed3556a8d072cb2b8571 upstream.

    Commit eff8728fe698 ("vmlinux.lds.h: Add PGO and AutoFDO input
    sections") added ".text.unlikely.*" and ".text.hot.*" due to an LLVM
    change [1].

    After another LLVM change [2], these sections are seen in some PowerPC
    builds, where there is a orphan section warning then build failure:

    $ make -skj"$(nproc)" \
    ARCH=powerpc CROSS_COMPILE=powerpc64le-linux-gnu- LLVM=1 O=out \
    distclean powernv_defconfig zImage.epapr
    ld.lld: warning: kernel/built-in.a(panic.o):(.text.unlikely.) is being placed in '.text.unlikely.'
    ...
    ld.lld: warning: address (0xc000000000009314) of section .text is not a multiple of alignment (256)
    ...
    ERROR: start_text address is c000000000009400, should be c000000000008000
    ERROR: try to enable LD_HEAD_STUB_CATCH config option
    ERROR: see comments in arch/powerpc/tools/head_check.sh
    ...

    Explicitly handle these sections like in the main linker script so
    there is no more build failure.

  • [ Upstream commit 87dbc209ea04645fd2351981f09eff5d23f8e2e9 ]

    Make mandatory in include/asm-generic/Kbuild and
    remove all arch/*/include/asm/local64.h arch-specific files since they
    only #include .

    This fixes build errors on arch/c6x/ and arch/nios2/ for
    block/blk-iocost.c.

    Build-tested on 21 of 25 arch-es. (tools problems on the others)

    Yes, we could even rename to
    and change all #includes to use
    instead.

    This is way to catch some cases of decrementer overflow, when the
    decrementer has underflowed an odd number of times, while MSR[EE] was
    disabled.

    With a typical small decrementer, a timer that fires when MSR[EE] is
    disabled will be "lost" if MSR[EE] remains disabled for between 4.3 and
    8.6 seconds after the timer expires. In any case, the decrementer
    interrupt would be taken at 8.6 seconds and the timer would be found at
    that point.

    So this check is for catching extreme latency events, and it prevents
    those latencies from being a further few seconds long. It's not obvious
    this is a good tradeoff. This is already a watchdog magnitude event and
    that situation is not improved a significantly with this check. For
    large decrementers, it's useless.

    Therefore remove this check, which avoids a mftb when enabling hard
    disabled interrupts (e.g., when enabling after coming from hardware
    interrupt handlers). Perhaps more importantly, it also removes the
    clunky MSR[EE] vs PACA_IRQ_HARD_DIS incoherency in soft-interrupt replay
    which simplifies the code.

    I noticed that iounmap() of msgr_block_addr before return from
    mpic_msgr_probe() in the error handling case is missing. So use
    devm_ioremap() instead of just ioremap() when remapping the message
    register block, so the mapping will be automatically released on
    probe failure.

  • commit d6718941a2767fb383e105d257d2105fe4f15f0e upstream.

    It's very easy to crash the kernel right now by simply trying to
    enable memtrace concurrently, hammering on the "enable" interface

    loop.sh:
    #!/bin/bash

    dmesg --console-off

    while true; do
    echo 0x40000000 > /sys/kernel/debug/powerpc/memtrace/enable
    done

    [root@localhost ~]# loop.sh &
    [root@localhost ~]# loop.sh &

    Resulting quickly in a kernel crash. Let's properly protect using a
    mutex.

  • commit c74cf7a3d59a21b290fe0468f5b470d0b8ee37df upstream.

    We currently leak kernel memory to user space, because memory
    offlining doesn't do any implicit clearing of memory and we are
    missing explicit clearing of memory.

    Let's keep it simple and clear pages before removing the linear
    mapping.

  • commit b1198a88230f2ce50c271e22b82a8b8610b2eea9 upstream.

    We execute certain NPU2 setup code (such as mapping an LPID to a device
    in NPU2) unconditionally if an Nvlink bridge is detected. However this
    cannot succeed on POWER8NVL machines and errors appear in dmesg. This is
    harmless as skiboot returns an error and the only place we check it is
    vfio-pci but that code does not get called on P8+ either.

    This adds a check if pnv_npu2_xxx helpers are called on a machine with
    NPU2 which initializes pnv_phb::npu in pnv_npu2_init();
    pnv_phb::npu==NULL on POWER8/NVL (Naples).

    While at this, fix NULL derefencing in pnv_npu_peers_take_ownership/
    pnv_npu_peers_release_ownership which occurs when GPUs on mentioned P8s
    cause EEH which happens if "vfio-pci" disables devices using
    the D3 power state; the vfio-pci's disable_idle_d3 module parameter
    controls this and must be set on Naples. The EEH handling clears
    the entire pnv_ioda_pe struct in pnv_ioda_free_pe() hence
    the NULL derefencing. We cannot recover from that but at least we stop
    crashing.

    Tested on
    - POWER9 pvr=004e1201, Ubuntu 19.04 host, Ubuntu 18.04 vm,
    NVIDIA GV100 10de:1db1 driver 418.39
    - POWER8 pvr=004c0100, RHEL 7.6 host, Ubuntu 16.10 vm,

    When SMC1 is relocated and early debug is selected, the
    board hangs is ppc_md.setup_arch(). This is because ones
    the microcode has been loaded and SMC1 relocated, early
    debug writes in the weed.

    To allow smooth continuation, the SMC1 parameter RAM set up
    by the bootloader have to be copied into the new location.

  • commit 1891ef21d92c4801ea082ee8ed478e304ddc6749 upstream.

    fls() and fls64() are using __builtin_ctz() and _builtin_ctzll().
    On powerpc, those builtins trivially use ctlzw and ctlzd power
    instructions.

    Allthough those instructions provide the expected result with
    input argument 0, __builtin_ctz() and __builtin_ctzll() are
    documented as undefined for value 0.

    The easiest fix would be to use fls() and fls64() functions
    defined in include/asm-generic/bitops/builtin-fls.h and
    include/asm-generic/bitops/fls64.h, but GCC output is not optimal:

    00000388 :
    388: 2c 03 00 00 cmpwi r3,0
    38c: 41 82 00 10 beq 39c
    390: 7c 63 00 34 cntlzw r3,r3
    394: 20 63 00 20 subfic r3,r3,32
    398: 4e 80 00 20 blr
    39c: 38 60 00 00 li r3,0
    3a0: 4e 80 00 20 blr

    000003b0 :
    3b0: 2c 03 00 00 cmpwi r3,0
    3b4: 40 82 00 1c bne 3d0
    3b8: 2f 84 00 00 cmpwi cr7,r4,0
    3bc: 38 60 00 00 li r3,0
    3c0: 4d 9e 00 20 beqlr cr7
    3c4: 7c 83 00 34 cntlzw r3,r4
    3c8: 20 63 00 20 subfic r3,r3,32
    3cc: 4e 80 00 20 blr
    3d0: 7c 63 00 34 cntlzw r3,r3
    3d4: 20 63 00 40 subfic r3,r3,64
    3d8: 4e 80 00 20 blr

    When the input of fls(x) is a constant, just check x for nullity and
    return either 0 or __builtin_clz(x). Otherwise, use cntlzw instruction
    directly.

    For fls64() on PPC64, do the same but with __builtin_clzll() and
    cntlzd instruction. On PPC32, lets take the generic fls64() which
    will use our fls(). The result is as expected:

    00000388 :
    388: 7c 63 00 34 cntlzw r3,r3
    38c: 20 63 00 20 subfic r3,r3,32
    390: 4e 80 00 20 blr

    The placeholder for instruction selection should use the second
    argument's operand, which is %1, not %0. This could generate incorrect
    assembly code if the memory addressing of operand %0 is a different
    form from that of operand %1.

    Also remove the %Un placeholder because having %Un placeholders
    for two operands which are based on the same local var (ptep) doesn't
    make much sense. By the way, it doesn't change the current behaviour
    because "<>" constraint is missing for the associated "=m".

  • commit d5c243989fb0cb03c74d7340daca3b819f706ee7 upstream.

    We need r1 to be properly set before activating MMU, otherwise any new
    exception taken while saving registers into the stack in syscall
    prologs will use the user stack, which is wrong and will even lockup
    or crash when KUAP is selected.

    Do that by switching the meaning of r11 and r1 until we have saved r1
    to the stack: copy r1 into r11 and setup the new stack pointer in r1.
    To avoid complicating and impacting all generic and specific prolog
    code (and more), copy back r1 into r11 once r11 is save onto
    the stack.

    We could get rid of copying r1 back and forth at the cost of rewriting
    everything to use r1 instead of r11 all the way when CONFIG_VMAP_STACK
    is set, but the effort is probably not worth it for now.

    Threshold Event Counter Multiplier (TECM) is part of Monitor Mode

    Counter Exponent (TECE) is used to get threshould counter value.
    In Power10, this is a 8bit field, so patch fixes the
    current code to modify the MMCRA[TECM] extraction macro to
    handle this change. ISA v3.1 says this is a 7 bit field but
    POWER10 it's actually 8 bits which will hopefully be fixed
    in ISA v3.1 update.

    There are three ways pseries_suspend_begin() can be reached:

    1. When "mem" is written to /sys/power/state:

    kobj_attr_store()
    -> state_store()
    -> pm_suspend()
    -> suspend_devices_and_enter()
    -> pseries_suspend_begin()

    This never works because there is no way to supply a valid stream id
    using this interface, and H_VASI_STATE is called with a stream id of
    zero. So this call path is useless at best.

    2. When a stream id is written to /sys/devices/system/power/hibernate.
    pseries_suspend_begin() is polled directly from store_hibernate()
    until the stream is in the "Suspending" state (i.e. the platform is
    ready for the OS to suspend execution):

    dev_attr_store()
    -> store_hibernate()
    -> pseries_suspend_begin()

    3. When a stream id is written to /sys/devices/system/power/hibernate
    (continued). After #2, pseries_suspend_begin() is called once again
    from the pm core:

    dev_attr_store()
    -> store_hibernate()
    -> pm_suspend()
    -> suspend_devices_and_enter()
    -> pseries_suspend_begin()

    This is redundant because the VASI suspend state is already known to
    be Suspending.

    The begin() callback of platform_suspend_ops is optional, so we can
    simply remove that assignment with no loss of function.

    In Power9, L2/L3 bus events are always available as a
    "bank" of 4 events. To obtain the counts for any of the

    When perf record session is started with "-I" option, capturing registers
    on each sample calls is_sier_available() to check for the
    SIER (Sample Instruction Event Register) availability in the platform.
    This function in core-book3s accesses 'ppmu->flags'. If a platform specific
    PMU driver is not registered, ppmu is set to NULL and accessing its
    members results in a crash. Fix the crash by returning false in
    is_sier_available() if ppmu is not set.
