Hi Arjan, I hoped that the test patch below would help acpi_battery_init() on machines where it runs a lot of AML. I have a lenovo s10-3 where it was taking 900ms, and this patch seemed to reduce it to 600ms. However, I measured again and it seems to have gone _up_ to 1300ms - so perhaps there is some other factor determining how long that routine is taking? -Len diff --git a/drivers/acpi/osl.c b/drivers/acpi/osl.c index 65b25a3..4658f61 100644 --- a/drivers/acpi/osl.c +++ b/drivers/acpi/osl.c @@ -271,7 +271,7 @@ acpi_os_map_memory(acpi_physical_address phys, acpi_size size) /* * ioremap checks to ensure this is in reserved space */ - return ioremap((unsigned long)phys, size); + return ioremap_cache((unsigned long)phys, size); else return __acpi_map_table((unsigned long)phys, size); } -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
