0820 is almost a month old by now, did you verify if the same happens on
a recent kernel? We did fix a bunch of issues around this.
The 'ld' and 'std' instructions require a 4-byte aligned displacement
because they are DS-form instructions. But the "m" asm constraint
doesn't enforce that.
That can lead to build errors if the compiler chooses a non-aligned
displacement, as seen with GCC 14:
/tmp/ccuSzwiR.s: Assembler message
The housekeeping CPU masks, set up by the "isolcpus" and "nohz_full"
boot command line options, are used at boot time to exclude selected
CPUs from running some kernel housekeeping subsystems to minimize
disturbance to latency sensitive userspace applications such as DPDK.
This options can only be
Introduce infrastructure function housekeeping_update() to change
housekeeping_cpumask during runtime and adjust configurations of depended
subsystems.
Configuration adjustments of subsystems follow in subsequent patches.
Parent patch:
sched/isolation: Exclude dynamically isolated CPUs from house
Interrupts disturb real-time tasks on affined cpus.
To ensure CPU isolation for real-time tasks, interrupt handling must
be adjusted accordingly.
Non-managed interrupts can be configured from userspace,
while managed interrupts require adjustments in kernelspace.
Adjust status of managed interrupt
shell script for testing managed interrupts
status adjustments.
Targets: managed_irq_affinity_adjust(),
irq_restore_affinity_of_irq(), managed_irq_isolate()
Managed interrupts can be created in various ways. One of them:
1. create qcow2 image
2. run
virtme-ng -v --cpus 4 --rw --user r
Yes, Issue is still seen. Latest seen was on 6.11.0-rc7-next-20240910.
I am re-attempting Git Bisect. Will update the results, once I am done.

Some of the network drivers, like Mellanox, use core linux page_pool APIs

infrequent map/unmap calls for DMA mappings, thus increasing performance.

Hi Hari,
kernel test robot noticed the following build warnings:

Use the proper API instead of open coding it.
However it looks like kthreads here could be replaced by the use of a
per-cpu workqueue instead.
