| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dear RT folks! I'm pleased to announce the v5.15-rc4-rt8 patch set. Changes since v5.15-rc4-rt7: - Redo the i915 patches. Everyone with a i915 may help testing. The upstream thread is at https://lore.kernel.org/all/20211005150046.1000285-1-bigeasy@linutronix.de/ I'm also curious to find out if the uncore.lock lock can be made a raw_spinlock_t or if doing so pushes the latency through the roof. See https://lore.kernel.org/all/20211006164628.s2mtsdd2jdbfyf7g@linutronix.de/ Any help is welcome. - During the i915 rework, a preempt_disable_rt() section in the radeon driver has been dropped because there is a spinlock_t within this section. - The irq_work patch(es) have been reworked based on upstream's feedback. The irq_work is now no longer processed in softirq but by a per-CPU thread at the lowest RT priority. - The statistics accounting in networking has been reworked in order to decouple the seqcount_t "try lock" usage from statistics update and qdisc's running state. Patches by Ahmed S. Darwish. Known issues - netconsole triggers WARN. - The "Memory controller" (CONFIG_MEMCG) has been disabled. - Valentin Schneider reported a few splats on ARM64, see https://lkml.kernel.org/r/20210810134127.1394269-1-valentin.schneider@arm.com The delta patch against v5.15-rc4-rt7 is appended below and can be found here: https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.15/incr/patch-5.15-rc4-rt7-rt8.patch.xz You can get this release via the git tree at: git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v5.15-rc4-rt8 The RT patch against v5.15-rc4 can be found here: https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.15/older/patch-5.15-rc4-rt8.patch.xz The split quilt queue is available at: https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.15/older/patches-5.15-rc4-rt8.tar.xz Sebastian Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

Changes since v5.15-rc3-rt5: - A sequence counter in networking's bridge code was not annotated properly. Reported by Mike Galbraith patch by Thomas Gleixner. - Temporary export force_irqthreads_key so the i915 driver compiles as a module. - Dropped all need-resched checks from irq_poll and added a BH off/on section around the place that may raise softirqs in the CPU hotplug notifier. This is an equivalent replacement for the former checks. - Synchronize various patches (irq_work, sched, zsmalloc) with what has been posted upstream.

Changes since v5.15-rc2-rt2: - Remove kernel_fpu_resched(). A few ciphers were restructured and this function has no users and can be removed. - The cpuset code is using spinlock_t again. Since the mm/slub rework there is need to use raw_spinlock_t. - Allow to enable CONFIG_RT_GROUP_SCHED on RT again. The original issue can not be reproduced. Please test and report any issue. - The RCU warning, that has been fixed Valentin Schneider, has been replaced with a patch by Thomas Gleixner. There is another issue open in that area an Frederick Weisbecker is looking into it. - RCU lock accounting and checking has been reworked by Thomas Gleixner. A direct effect is that might_sleep() produces a warning if invoked in a RCU read section. Previously it would only trigger a warning in schedule() in such a situation. - The preempt_*_nort() macros have been removed. - The preempt_enable_no_resched() macro should behave like preempt_enable() on PREEMPT_RT but was was misplaced in v3.14-rt1 and has has been corrected now.

The logic in migratable() for UP has been changed and the function itself was renamed (which is different as posted to the list). - The printk.h includes a locking header directly. This unbreaks the POWER and POWER64 build and makes another patch (an earlier attempt to unbreak recursive includes) obsolete. - Update the SLUB series by Vlastimil Babka to slub-local-lock-v4r4: - Clark Williams reported a crash in the SLUB memory allocator.

Patch by Valentin Schneider. - Update RT's locking patches to what has been merge tip/locking/core. A visible change is the definition of local_lock_t on PREEMPT_RT. As a result the access to local_lock_t's dep_map is the same on RT & !RT. Known issues - netconsole triggers WARN. - The "Memory controller" (CONFIG_MEMCG) has been disabled. - A RCU and ARM64 warning has been fixed by Valentin Schneider.
