Hello,
This is the third version of a patch series initially posted in
October 2015, under the title:
[PATCH 0/5] Fix regression introduced by set_irq_flags() removal
at the time, the regression was worked around in commit
353d6d6c82e5d2533ba22e7f9fb081582bf50dc2 ("irqchip/armada-370-xp: Fix
regression by clearing IRQ_NOAUTOEN") and this series brings the
proper fix for the original issue, while reverting the work around.
Changes since v2:
- Rebased on top of v4.12-rc1.
Changes since v1:
- Rebased on top of v4.10.
- Patch "kernel: irq: implement is_enabled_percpu_irq()" dropped,
since it has been merged upstream as commit
f0cb32207307e9d7b3ee8117078b7a37f8d0166e ("genirq: Implement
irq_percpu_is_enabled()")
- Patch "irqchip: armada-370-xp: prepare additions to
armada_xp_mpic_secondary_init()" dropped, since similar changes
were merged as part of the overall CPU hotplug rework.
- Patches "irqchip: armada-370-xp: re-order register definitions" and
"irqchip: armada-370-xp: document the overall driver logic" moved
at the beginning of the series.
- Acked-by added on "irqchip: armada-370-xp: re-order register
definitions" and "irqchip: armada-370-xp: document the overall
driver logic"
- In patch "irqchip: armada-370-xp: document the overall driver
logic", fix minor presentation detail in the ASCII art diagram.
- In patch "irqchip: armada-370-xp: re-enable per-CPU interrupts at
resume time":
- Move the per-CPU interrupt re-enabling logic for secondary cores
into a utility function armada_xp_mpic_reenable_percpu() called
by both armada_xp_mpic_starting_cpu() and
mpic_cascaded_starting_cpu().
- Instead of iterating on all IRQs and filtering the per-CPU ones,
only iterate on the first ARMADA_370_XP_MAX_PER_CPU_IRQS, which
are the only per-CPU ones. Suggested by Grégory Clement.
- Use the irq_percpu_is_enabled() API, which was the one actually
merged, instead of the one originally proposed in the v1 of this
series.
- Addition of a patch reverting the work around.
Thanks,
Thomas
