[PATCH] perf/x86/intel: Correct wrong 'or' operation for pmu capabilities

by Dapeng Mi

When running perf-stat command on Intel hybrid platform, perf-stat reports the following errors. sudo taskset -c 7 ./perf stat -vvvv -e cpu_atom/instructions/ sleep 1 Opening: cpu/cycles/:HG ------------------------------------------------------------ perf_event_attr: type 0 (PERF_TYPE_HARDWARE) config 0xa00000000 disabled 1 ------------------------------------------------------------ sys_perf_event_open: pid 0 cpu -1 group_fd -1 flags 0x8 sys_perf_event_open failed, error -16 Performance counter stats for 'sleep 1': <not counted> cpu_atom/instructions/ It looks the cpu_atom/instructions/ event can't be enabled on atom pmu even the process is pinned on atom core. The investigation shows that exclusive_event_init() helper always returns -EBUSY error in the perf event creation. That's strange since the atom pmu should not be a exclusive PMU. Further investigation shows the issue is introduced by commit 97588df87b56 ("perf/x86/intel: Add common intel_pmu_init_hybrid()"). The commit originally intents to clear the bit PERF_PMU_CAP_AUX_OUTPUT from pmu capabilities if intel_cap.pebs_output_pt_available is not set, but it incorrectly uses 'or' operation and leads to all pmu capabilities bits are set to 1 except bit PERF_PMU_CAP_AUX_OUTPUT. Testing this fix on Intel hybrid platforms, the observed issues disappear.

Since we don't use FPU in kernel for now, TIF_USEDFPU must be set accidentally for that kthread. Inspecting the code it seems like create_io_thread may be invoked from threads that have FP context alive, causing TIF_USEDFPU to be copied from that context to kthread unexpectedly. Move around code blocks to ensure flags regarding lazy hardware context get cleared for kernel threads as well.

[PATCH v2 0/2] Add support for xhci-sg-trb-cache-size-quirk

by Prashanth K

XHCI_SG_TRB_CACHE_SIZE_QUIRK was introduced in XHCI to resolve XHC timeout while using SG buffers, which was seen Synopsys XHCs. The support for this isn't present in DWC3 layer, this series enables XHCI_SG_TRB_CACHE_SIZE_QUIRK since this is needed for DWC3 controller. Changes in v2: Included xhci-plat.c to pass the quirks via priv data. Added Fixes tag in device tree binding patch.

[PATCH] drm/ast: Disconnect BMC if physical connector is connected

by Thomas Zimmermann

Many user-space compositors fail with mode setting if a CRTC has more than one connected connector. This is the case with the BMC on Aspeed systems. Work around this problem by setting the BMC's connector status to disconnected when the physical connector has a display attached. This way compositors will only see one connected connector at a time; either the physical one or the BMC.

[PATCH 5.15 01/17] xfs: refactor buffer cancellation table allocation

by Leah Rumancik

From: "Darrick J. Wong" <djwong(a)kernel.org> [ Upstream commit 2723234923b3294dbcf6019c288c87465e927ed4 ] Move the code that allocates and frees the buffer cancellation tables used by log recovery into the file that actually uses the tables. This is a precursor to some cleanups and a memory leak fix. ( backport: dependency of 8db074bd84df5ccc88bff3f8f900f66f4b8349fa ) Signed-off-by: Darrick J.

[PATCH 07/11] arm64: dts: qcom: sdm670: fix USB wakeup interrupt types
