Parametrized events are not only a powerpc domain. They occur on other platforms too (e.g. aarch64). They should be ignored in this testcase, since proper setup of the parameters is out of scope of this script. Let's not filter them out by PMU name, but rather based on the fact that they expect a parameter. Fixes: 451ed805 ("perf test: Fix "all PMU test" to skip hv_24x7/hv_gpci tests on powerpc") Signed-off-by:

perf tools: Add .DELETE_ON_ERROR special Makefile target to clean up partially updated files on error. As kbuild, this adds .DELETE_ON_ERROR special target to clean up partially updated files on error. A known issue is the empty vmlinux.h generted by bpftool if it failed to dump btf info. Reviewed-by:

The -Y/--type-filter option is to filter the result for specific lock types only. It can accept comma-separated values. Note that it would accept type names like one in the output. spinlock, mutex, rwsem:R and so on. For RW-variant lock types, it converts the name to the both variants. In other words, "rwsem" is same as "rwsem:R,rwsem:W". Also note that "mutex" has two different encoding - one for sleeping wait, another for optimistic spinning. Add "mutex-spin" entry for the lock_type_table so that we can add it for "mutex" under the table. $ sudo ./perf lock record -a -- ./perf bench sched messaging $ sudo ./perf lock con -E 5 -Y spinlock contended total wait max wait avg wait type caller 802 1.26 ms 11.73 us 1.58 us spinlock __wake_up_common_lock+0x62 13 787.16 us 105.44 us 60.55 us spinlock remove_wait_queue+0x14 12 612.96 us 78.70 us 51.08 us spinlock prepare_to_wait+0x27 114 340.68 us 12.61 us 2.99 us spinlock try_to_wake_up+0x1f5 83 226.38 us 9.15 us 2.73 us spinlock folio_lruvec_lock_irqsave+0x5e Committer notes: Make get_type_flag() return UINT_MAX for error instad of -1UL, as that function returns 'unsigned int' and we store the value on a 'unsigned int' 'flags' variable which makes clang unhappy: 35 98.23 fedora:37 : FAIL clang version 15.0.6 (Fedora 15.0.6-1.fc37) builtin-lock.c:2012:14: error: result of comparison of constant 18446744073709551615 with expression of type 'unsigned int' is always true [-Werror,-Wtautological-constant-out-of-range-compare] if (flags != -1UL) { ~~~~~ ^ ~~~~ builtin-lock.c:2021:14: error: result of comparison of constant 18446744073709551615 with expression of type 'unsigned int' is always true [-Werror,-Wtautological-constant-out-of-range-compare] if (flags != -1UL) { ~~~~~ ^ ~~~~ builtin-lock.c:2037:14: error: result of comparison of constant 18446744073709551615 with expression of type 'unsigned int' is always true [-Werror,-Wtautological-constant-out-of-range-compare] if (flags != -1UL) { ~~~~~ ^ ~~~~ 3 errors generated.

perf debug: Set debug_peo_args and redirect_to_stderr variable to correct values in perf_quiet_option() When perf uses quiet mode, perf_quiet_option() sets the 'debug_peo_args' variable to -1, and display_attr() incorrectly determines the value of 'debug_peo_args'. As a result, unexpected information is displayed.

Pull more nfsd updates from Chuck Lever: "This contains a number of crasher fixes that were not ready for the initial pull request last week. In particular, Jeff's patch attempts to address reference count underflows in NFSD's filecache, which have been very difficult to track down because there is no reliable reproducer. Common failure modes: https://bugzilla.kernel.org/show_bug.cgi?id=216691#c11 https://bugzilla.kernel.org/show_bug.cgi?id=216674#c6 https://bugzilla.redhat.com/show_bug.cgi?id=2138605 The race windows were found by inspection and the clean-ups appear sensible and pass regression testing, so we include them here in the hope that they address the problem. However we remain vigilant because we don't have 100% certainty yet that the problem is fully addressed.

Pull rdma fixes from Jason Gunthorpe: "Fix two build warnings on 32 bit platforms It seems the linux-next CI and 0-day bot are not testing enough 32 bit configurations, as soon as you merged the rdma pull request there were two instant reports of warnings on these sytems that I would have thought should have been covered by time in linux-next Anyhow, here are the fixes so people don't hit problems with -Werror" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: RDMA/siw: Fix pointer cast warning RDMA/rxe: Fix compile warnings on 32-bit

Pull gfs2 updtaes from Andreas Gruenbacher: - Revert a change to delete_work_func() that has gone wrong in commit c412a97c ("gfs2: Use TRY lock in gfs2_inode_lookup for UNLINKED inodes"). - Avoid dequeuing GL_ASYNC glock holders twice by first checking if the holder is still queued. - gfs2: Always check the inode size of inline inodes when reading in inodes to prevent corrupt filesystem images from causing weid errors. - Properly handle a race between gfs2_create_inode() and gfs2_inode_lookup() that causes insert_inode_locked4() to return -EBUSY. - Fix and clean up the interaction between gfs2_create_inode() and gfs2_evict_inode() by completely handling the inode deallocation and destruction in gfs2_evict_inode(). - Remove support for glock holder auto-demotion as we have no current plans of using this feature again. - And a few more minor cleanups and clarifications. * tag 'gfs2-v6.1-rc7-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: gfs2: Remove support for glock holder auto-demotion (2) gfs2: Remove support for glock holder auto-demotion gfs2: Minor gfs2_try_evict cleanup gfs2: Partially revert gfs2_inode_lookup change gfs2: Add gfs2_inode_lookup comment gfs2: Uninline and improve glock_{set,clear}_object gfs2: Simply dequeue iopen glock in gfs2_evict_inode gfs2: Clean up after gfs2_create_inode rework gfs2: Avoid dequeuing GL_ASYNC glock holders twice gfs2: Make gfs2_glock_hold return its glock argument gfs2: Always check inode size of inline inodes gfs2: Cosmetic gfs2_dinode_{in,out} cleanup gfs2: Handle -EBUSY result of insert_inode_locked4 gfs2: Fix and clean up create / evict interaction gfs2: Clean up initialization of "ip" in gfs2_create_inode gfs2: Get rid of ghs[] in gfs2_create_inode gfs2: Add extra error check in alloc_dinode

Since 2f2940d1 ("genirq/msi: Remove filter from msi_free_descs_free_range()"), the core MSI code relies on the msi_desc->irq field to have been cleared before the descriptor can be freed, as it indicates that there is no association with a device anymore. The irq domain code provides this guarantee, and so does s390, which is one of the two architectures not using irq domains for MSIs. Powerpc, however, is missing this particular requirements, leading in a splat and leaked MSI descriptors. Adding the now required irq reset to the handful of powerpc backends that implement MSIs fixes that particular problem. Reported-by:
