Hi,
The config option CONFIG_HARDIRQS_SW_RESEND Is enabled by default for ARM64, should it be
enabled by default or only on specific cases.
With this configuration enabled the following issue is observed.
resend_irqs() tasklet doesn't honor the interrupt affinity configuration setting as the
taskset blindly calls the desc->handle_irq() by checking the bits set in the IRQ_BITMAP_BITS.
This would lead to handling interrupt in the cores were affinity is not set for a particular interrupt.
Any thoughts??
Regards
-George
