--- Comment #5 from Zhang Rui ([email protected]) ---
first of all, the time is not spent in acpi_ev_initialize_gpe_block, but the
work after it.

in acpi_scan_init()
[    0.047213] ACPI: Enabled 1 GPEs in block 00 to 1F
is printed by acpi_update_all_gpes().

and
[    0.061357] acpi ACPI0003:01: ACPI dock station (docks/bays count: 1)
is printed by acpi_bus_check_add() -> acpi_scan_init_hotplug() ->
acpi_dock_add()

the time looks long (14ms) just because we don't print that much log, and we're
actually doing quite a lot of things.


54ms acpi_init() is really a good number to me, and actually, I'm wondering how
you did this. probably you're using small and clean ACPI tables.

However, for the acpi_init() time cost, if you have a platform that acpi_init()
takes longer than 1s, we will work on it, if 54ms, sorry, no, we won't put any
effort on this as this does not sounds a really kernel issue to me.

Paul, please feel free to reopen it if you still have any objections. :)
