[PATCH v2 5/7] perf/x86/amd/ibs: Fix raw sample data accumulation

by Kim Phillips

Neither IbsBrTarget nor OPDATA4 are populated in IBS Fetch mode. Don't accumulate them into raw sample user data in that case. Also, in Fetch mode, add saving the IBS Fetch Control Extended MSR. Technically, there is an ABI change here with respect to the IBS raw sample data format, but I don't see any perf driver version information being included in perf.data file headers, but, existing users can detect whether the size of the sample record has reduced by 8 bytes to determine whether the IBS driver has this fix.

[tip: perf/core] arch/x86/amd/ibs: Fix re-arming IBS Fetch

Indeed, the PPR for AMD Family 17h Model 31h B0 55803 Rev 0.54 - Sep 12, 2019 states "The periodic fetch counter is set to IbsFetchCnt [...] when IbsFetchEn is changed from 0 to 1." Explicitly set IbsFetchEn to 0 and then to 1 when re-enabling IBS Fetch, so the driver properly resets the internal counter to 0 and IBS Fetch starts counting again. A family 15h machine tested does not have this problem, and the extra wrmsr is also not needed on Family 19h, so only do the extra wrmsr on families 16h through 18h.

[PATCH] intel-iommu: don't disable ATS for device without page aligned request

by Jason Wang

Commit 61363c1474b1 ("iommu/vt-d: Enable ATS only if the device uses page aligned address.") disables ATS for device that can do unaligned page request. This looks wrong, since the commit log said it's because the page request descriptor doesn't support reporting unaligned request. A victim is Qemu's virtio-pci which doesn't advertise the page aligned address. Fixing by disable PRI instead of ATS if device doesn't have page aligned request.

[PATCH] mm: don't rely on system state to detect hot-plug operations

by Laurent Dufour

In register_mem_sect_under_node() the system_state’s value is checked to detect whether the operation the call is made during boot time or during an hot-plug operation. Unfortunately, that check is wrong on some architecture, and may lead to sections being registered under multiple nodes if node's memory ranges are interleaved. This can be seen on PowerPC LPAR after multiple memory hot-plug and hot-unplug operations are done. At the next reboot the node's memory ranges can be interleaved and since the call to link_mem_sections() is made in topology_init() while the system is in the SYSTEM_SCHEDULING state, the node's id is not checked, and the sections registered multiple times. In that case, the system is able to boot but later hot-plug operation may lead to this panic because the node's links are correctly broken: ------------[ cut here ]------------ kernel BUG at /Users/laurent/src/linux-ppc/mm/memory_hotplug.c:1084!

[git:media_tree/fixes] media: cec-adap.c: don't use flush_scheduled_work()

by Mauro Carvalho Chehab

This is an automatic generated email to let you know that the following patch were queued: Subject: media: cec-adap.c: don't use flush_scheduled_work() Author: Hans Verkuil <hverkuil-cisco(a)xs4all.nl> Date: Tue Sep 8 12:02:53 2020 +0200 For some inexplicable reason I decided to call flush_scheduled_work() instead of cancel_delayed_work_sync(). The problem with that is that flush_scheduled_work() waits for *all* queued scheduled work to be completed instead of just the work itself. This can cause a deadlock if a CEC driver also schedules work that takes the same lock. See the comments for flush_scheduled_work() in linux/workqueue.h. This is exactly what has been observed a few times. This patch simply replaces flush_scheduled_work() by cancel_delayed_work_sync().

✅ PASS: Test report for kernel 5.8.8-4f447bf.cki (stable)

by CKI Project

Hello, We ran automated tests on a recent commit from this kernel tree: Kernel repo: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git Commit: 4f447bf95fdc - Linux 5.8.8 The results of these automated tests are provided below. Overall result: PASSED Merge: OK Compile: OK Tests: OK All kernel binaries, config files, and logs are available for download here: https://arr-cki-prod-datawarehouse-public.s3.amazonaws.com/index.html?prefi… Please reply to this email if you have any questions about the tests that we ran or if you have any suggestions on how to make future tests more effective. ,-. ,-.

Aborted tests ------------- Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report. Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱.
