由 Borislav Petkov 提交于
Stephane Eranian reported that doing a scheduler latency measurements with perf on AMD doesn't work out as expected due to the fact that the sched_clock() granularity is too coarse, i.e. done in jiffies due to the sched_clock_stable not set, which, if set, would mean that we get to use the TSC as sample source which would give us much higher precision. However, there's no reason not to set sched_clock_stable on AMD because all families from F10h and upwards do have an invariant TSC and have the CPUID flag to prove (CPUID_8000_0007_EDX[8]).

This patch fixes an issue where perf report shows nan% for certain perf.data files. The below is from a report for a do_fork probe: -nan% sshd [kernel.kallsyms] [k] do_fork -nan% packagekitd [kernel.kallsyms] [k] do_fork -nan% dbus-daemon [kernel.kallsyms] [k] do_fork -nan% bash [kernel.kallsyms] [k] do_fork A git bisect shows commit f3bda2c9 as the cause. However, looking back through the git history, I saw commit 640c03ce which seems to have removed the required initialization for perf_sample->period. The problem only started showing after commit f3bda2c9. The below patch re-introduces the initialization and it fixes the problem for me. With the below patch, for the same perf.data: 73.08% bash [kernel.kallsyms] [k] do_fork 8.97% 11-dhclient [kernel.kallsyms] [k] do_fork 6.41% sshd [kernel.kallsyms] [k] do_fork 3.85% 20-chrony [kernel.kallsyms] [k] do_fork 2.56% sendmail [kernel.kallsyms] [k] do_fork This patch applies over current linux-tip commit 9949284.

In some perf ancient versions we used '[kernel.kallsyms._text]' as the name for the kernel map. This got changed with commit: perf: 'perf kvm' tool for monitoring guest performance from host commit a1645ce1 Author: Zhang, Yanmin <yanmin_zhang@linux.intel.com> and we started to use following name '[kernel.kallsyms]_text'. This name change is important for the report code dealing with ancient perf data. When processing the kernel map event, we need to recognize the old naming (dont match the last ']') and initialize the kernel map correctly. The subsequent call to maps__set_kallsyms_ref_reloc_sym deals with the superfluous ']' to get correct symbol name.

With the new throttling/unthrottling code introduced with commit: e050e3f0 ("perf: Fix broken interrupt rate throttling") we occasionally hit two WARN_ON_ONCE() checks in: - intel_pmu_pebs_enable() - intel_pmu_lbr_enable() - x86_pmu_start() The assertions are no longer problematic. There is a valid path where they can trigger but it is harmless. The assertion can be triggered with: $ perf record -e instructions:pp .... Leading to paths: intel_pmu_pebs_enable intel_pmu_enable_event x86_perf_event_set_period x86_pmu_start perf_adjust_freq_unthr_context perf_event_task_tick scheduler_tick And: intel_pmu_lbr_enable intel_pmu_enable_event x86_perf_event_set_period x86_pmu_start perf_adjust_freq_unthr_context. perf_event_task_tick scheduler_tick cpuc->enabled is always on because when we get to perf_adjust_freq_unthr_context() the PMU is not totally disabled. Furthermore when we need to adjust a period, we only stop the event we need to change and not the entire PMU. Thus, when we re-enable, cpuc->enabled is already set. Note that when we stop the event, both pebs and lbr are stopped if necessary (and possible).

The rbd_client structure uses a kref to arrange for cleaning up and freeing an instance when its last reference is dropped. The cleanup routine is rbd_client_release(), and one of the things it does is delete the rbd_client from rbd_client_list. It acquires node_lock to do so, but the way it is done is still not safe. The problem is that when attempting to reuse an existing rbd_client, the structure found might already be in the process of getting destroyed and cleaned up. Here's the scenario, with "CLIENT" representing an existing rbd_client that's involved in the race: Thread on CPU A | Thread on CPU B --------------- | --------------- rbd_put_client(CLIENT) | rbd_get_client() kref_put() | (acquires node_lock) kref->refcount becomes 0 | __rbd_client_find() returns CLIENT calls rbd_client_release() | kref_get(&CLIENT->kref); | (releases node_lock) (acquires node_lock) | deletes CLIENT from list | ...and starts using CLIENT... (releases node_lock) | and frees CLIENT | <-- but CLIENT gets freed here Fix this by having rbd_put_client() acquire node_lock. The result could still be improved, but at least it avoids this problem. Signed-off-by: NAlex Elder <elder@dreamhost.com> Signed-off-by: NSage Weil <sage@newdream.net>

Lockdep was reporting a possible circular lock dependency in dentry_lease_is_valid(). That function needs to sample the session's s_cap_gen and and s_cap_ttl fields coherently, but needs to do so while holding a dentry lock. The s_cap_lock field was being used to protect the two fields, but that can't be taken while holding a lock on a dentry within the session. In most cases, the s_cap_gen and s_cap_ttl fields only get operated on separately. But in three cases they need to be updated together. Implement a new lock to protect the spots updating both fields atomically is required. Signed-off-by: NAlex Elder <elder@dreamhost.com> Reviewed-by: NSage Weil <sage@newdream.net>

Initializing debufs under monc->mutex introduces a lock dependency for sb->s_type->i_mutex_key, which (combined with several other dependencies) leads to an annoying lockdep warning. There's no particular reason to do the debugfs setup under this lock, so move it out. It used to be the case that our first monmap could come from the OSD; that is no longer the case with recent servers, so we will reliably set up the client entry during the initial authentication. We don't have to worry about racing with debugfs teardown by ceph_debugfs_client_cleanup() because ceph_destroy_client() calls ceph_msgr_flush() first, which will wait for the message dispatch work to complete (and the debugfs init to complete).

Evergreen and NI blit copy was broken if the buffer maps to a rectangle whose one dimension is 16384 (max dimension allowed by these chips). In the mainline kernel, the problem is exposed only when buffers are very large (1G), but it's still a problem. The problem could be exposed for smaller buffers if anyone modifies the algorithm for rectangle construction in r600_blit_create_rect() (the reason why someone would modify that algorithm is to tune the performance of buffer moves). The root cause was in i2f() function which only operated on range between 0 and 16383. Fix this by extending the range of i2f() function to 0 to 32767. While at it improve the function so that the range can be easily extended in the future (if it becomes necessary), cleanup lines over 80 characters, and replace in-line comments with one strategic comment that explains the crux of the function. Credits to michel@daenzer.net for pointing out the root cause of the bug. v2: Fix I2F_MAX_INPUT constant definition goof and warn only once if input argument is out of range.

This copy of longlong.h is extremely dated and results in compile errors on sparc32 when MPILIB is enabled, copy over the more uptodate implementation from arch/sparc/math/sfp-util_32.h Reported-by: NAl Viro <viro@ZenIV.linux.org.uk> Signed-off-by: NDavid S.

Both sparc 32-bit's software divide assembler and MPILIB provide clz_tab[] with identical contents. Break it out into a seperate object file and select it when SPARC32 or MPILIB is set.

InfiniBand/RDMA fixes for 3.3: - Fix a crash due to a regression (uninitialized refcnt) introduced in 3.2 with XRC support. - Close race in how ucma reports events when connect fails. - Process vendor-specific MADs in mlx4 so that eg FDR-10 data rate works. - Fix regression in qib caused by over-aggressive PCIe tuning. - Other small fixes for hardware drivers (ipath, nes, qib). * tag 'rdma-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband: RDMA/nes: Copyright update IB/mlx4: pass SMP vendor-specific attribute MADs to firmware RDMA/nes: Fix fast memory registration opcode RDMA/nes: Fix fast memory registration length RDMA/ucma: Discard all events for new connections until accepted IB/qib: Roll back PCIe tuning change IB/qib: Use GFP_ATOMIC when locks are held RDMA/nes: Add missing rcu_read_unlock() in nes_addr_resolve_neigh() RDMA/nes: Fix for sending MPA reject frame IB/ipath: Calling PTR_ERR() on right variable in create_file() RDMA/core: Fix kernel panic by always initializing qp->usecnt
