ACPICA: Add a depth argument to acpi_execute_reg_methods()

2024-08-29T15:35:37Z

commit cdf65d73e001fde600b18d7e45afadf559425ce5 upstream. A subsequent change will need to pass a depth argument to acpi_execute_reg_methods(), so prepare that function for it. No intentional functional changes. Signed-off-by: Rafael J.

ACPI: EC: Evaluate orphan _REG under EC device

2024-06-13T09:28:54Z

After starting to install the EC address space handler at the ACPI namespace root, if there is an "orphan" _REG method in the EC device's scope, it will not be evaluated any more. This breaks EC operation regions on some systems, like Asus gu605. To address this, use a wrapper around an existing ACPICA function to look for an "orphan" _REG method in the EC device scope and evaluate it if present.

ACPI: sleep: Avoid breaking S3 wakeup due to might_sleep()

2023-06-15T16:05:19Z

The addition of might_sleep() to down_timeout() caused the latter to enable interrupts unconditionally in some cases, which in turn broke the ACPI S3 wakeup path in acpi_suspend_enter(), where down_timeout() is called by acpi_disable_all_gpes() via acpi_ut_acquire_mutex(). Namely, if CONFIG_DEBUG_ATOMIC_SLEEP is set, might_sleep() causes might_resched() to be used and if CONFIG_PREEMPT_VOLUNTARY is set, this triggers __cond_resched() which may call preempt_schedule_common(), so __schedule() gets invoked and it ends up with enabled interrupts (in the prev == next case). Now, enabling interrupts early in the S3 wakeup path causes the kernel to crash. Address this by modifying acpi_suspend_enter() to disable GPEs without attempting to acquire the sleeping lock which is not needed in that code path anyway.
