Since BUG() and WARN() may use a trap (e.g. UD2 on x86) to get the address where the BUG() has occurred, kprobes can not do single-step out-of-line that instruction. So prohibit probing on such address. Without this fix, if someone put a kprobe on WARN(), the kernel will crash with invalid opcode error instead of outputing warning message, because kernel can not find correct bug address.

Pull x86 fixes from Thomas Gleixner: "A set of fixes for x86: - Fix the bogus detection of 32bit user mode for uretprobes which caused corruption of the user return address resulting in application crashes. In the uprobes handler in_ia32_syscall() is obviously always returning false on a 64bit kernel. Use user_64bit_mode() instead which works correctly. - Prevent large page splitting when ftrace flips RW/RO on the kernel text which caused iTLB performance issues. Ftrace wants to be converted to text_poke() which avoids the problem, but for now allow large page preservation in the static protections check when the change request spawns a full large page. - Prevent arch_dynirq_lower_bound() from returning 0 when the IOAPIC is configured via device tree. In the device tree case the GSI 1:1 mapping is meaningless therefore the lower bound which protects the GSI range on ACPI machines is irrelevant. Return the lower bound which the core hands to the function instead of blindly returning 0 which causes the core to allocate the invalid virtual interupt number 0 which in turn prevents all drivers from allocating and requesting an interrupt. - Remove the bogus initialization of LDR and DFR in the 32bit bigsmp APIC driver. That uses physical destination mode where LDR/DFR are ignored, but the initialization and the missing clear of LDR caused the APIC to be left in a inconsistent state on kexec/reboot. - Clear LDR when clearing the APIC registers so the APIC is in a well defined state. - Initialize variables proper in the find_trampoline_placement() code. - Silence GCC( build warning for the real mode part of the build" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mm/cpa: Prevent large page split when ftrace flips RW on kernel text x86/build: Add -Wnoaddress-of-packed-member to REALMODE_CFLAGS, to silence GCC9 build warning x86/boot/compressed/64: Fix missing initialization in find_trampoline_placement() x86/apic: Include the LDR when clearing out APIC registers x86/apic: Do not initialize LDR and DFR for bigsmp uprobes/x86: Fix detection of 32-bit user mode x86/apic: Fix arch_dynirq_lower_bound() bug for DT enabled machines -

Now that there's a common version of the decoder for all tools, use it instead of the local copy. Also use perf's check-headers.sh script to diff the decoder files to make sure they remain in sync with the kernel version. Objtool has a similar check. Committer notes: Had to keep this all pointing explicitely to x86 headers/files, i.e. instead of asm/isnn.h we had to use ../include/asm/insn.h when the files were in differemt dirs, or just replace "<asm/foo.h>" with "foo.h". This way we continue to be able to process perf.data files with Intel PT traces in distros other than x86. Also fixed up the awk script paths to use $(srcdir)/tools/arch instead or relative directories so that we keep detached tarballs (make help | grep perf) working. For now the include lines in these headers are being ignored so as not to flag false reports of kernel/tools out of sync. Signed-off-by:

Josh Poimboeuf authored
The kernel tree has three identical copies of the x86 instruction decoder. Two of them are in the tools subdir. The tools subdir is supposed to be completely standalone and separate from the kernel. So having at least one copy of the kernel decoder in the tools subdir is unavoidable. However, we don't need *two* of them. Move objtool's copy of the decoder to a shared location, so that perf will also be able to use it. Signed-off-by:

Some uncore metrics don't work as expected. For example, on cascadelakex: root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_BANDWIDTH.TOTAL -a -- sleep 1 Performance counter stats for 'system wide': 1841092 unc_m_pmm_rpq_inserts 3680816 unc_m_pmm_wpq_inserts 1.001775055 seconds time elapsed root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_READ_LATENCY -a -- sleep 1 Performance counter stats for 'system wide': 860649746 unc_m_pmm_rpq_occupancy.all 1840557 unc_m_pmm_rpq_inserts 12790627455 unc_m_clockticks 1.001773348 seconds time elapsed No metrics 'UNC_M_PMM_BANDWIDTH.TOTAL' or 'UNC_M_PMM_READ_LATENCY' are reported. The issue is, the case of an alias expanding to mulitple events is not supported, typically the uncore events. (see comments in find_evsel_group()). For UNC_M_PMM_BANDWIDTH.TOTAL in above example, the expanded event group is '{unc_m_pmm_rpq_inserts,unc_m_pmm_wpq_inserts}:W', but the actual events passed to find_evsel_group are: unc_m_pmm_rpq_inserts unc_m_pmm_rpq_inserts unc_m_pmm_rpq_inserts unc_m_pmm_rpq_inserts unc_m_pmm_rpq_inserts unc_m_pmm_rpq_inserts unc_m_pmm_wpq_inserts unc_m_pmm_wpq_inserts unc_m_pmm_wpq_inserts unc_m_pmm_wpq_inserts unc_m_pmm_wpq_inserts unc_m_pmm_wpq_inserts For this multiple events case, it's not supported well. This patch introduces a new field 'metric_leader' in struct evsel. The first event is considered as a metric leader. For the rest of same events, they point to the first event via it's metric_leader field in struct evsel. This design is for adding the counting results of all same events to the first event in group (the metric_leader). With this patch, root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_BANDWIDTH.TOTAL -a -- sleep 1 Performance counter stats for 'system wide': 1842108 unc_m_pmm_rpq_inserts # 337.2 MB/sec UNC_M_PMM_BANDWIDTH.TOTAL 3682209 unc_m_pmm_wpq_inserts 1.001819706 seconds time elapsed root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_READ_LATENCY -a -- sleep 1 Performance counter stats for 'system wide': 861970685 unc_m_pmm_rpq_occupancy.all # 219.4 ns UNC_M_PMM_READ_LATENCY 1842772 unc_m_pmm_rpq_inserts 12790196356 unc_m_clockticks 1.001749103 seconds time elapsed Now we can see the correct metrics 'UNC_M_PMM_BANDWIDTH.TOTAL' and 'UNC_M_PMM_READ_LATENCY'.

Some metrics define the scale unit, such as { "BriefDescription": "Intel Optane DC persistent memory read latency (ns). Derived from unc_m_pmm_rpq_occupancy.all", "Counter": "0,1,2,3", "EventCode": "0xE0", "EventName": "UNC_M_PMM_READ_LATENCY", "MetricExpr": "UNC_M_PMM_RPQ_OCCUPANCY.ALL / UNC_M_PMM_RPQ_INSERTS / UNC_M_CLOCKTICKS", "MetricName": "UNC_M_PMM_READ_LATENCY", "PerPkg": "1", "ScaleUnit": "6000000000ns", "UMask": "0x1", "Unit": "iMC" }, For above example, the ratio should be, ratio = (UNC_M_PMM_RPQ_OCCUPANCY.ALL / UNC_M_PMM_RPQ_INSERTS / UNC_M_CLOCKTICKS) * 6000000000 But in current code, the ratio is not scaled ( * 6000000000) With this patch, the ratio is scaled and the unit (ns) is printed. For example, # 219.4 ns UNC_M_PMM_READ_LATENCY Signed-off-by: -
Jin Yao authored
The function convert_scale() can be used to convert string to unit and scale. For example, s = "6000000000ns"; convert_scale(s, &unit, &scale); unit = "ns", scale = 6000000000. Currently this function is static. This patch renames the function to perf_pmu__convert_scale and changes the function to global. No functional change. Signed-off-by:
