2017-01-10memhp: don't generate memory hotplug AML if it's not enabled/supportedIgor Mammedov
That reduces DSDT by 910 bytes when memory hotplug isn't enabled. While doing so drop intermediate variables/arguments passing around ACPI_MEMORY_HOTPLUG_IO_LEN and making it local to memory_hotplug.c, hardcoding it there as it can't change. Also don't pass around ACPI_MEMORY_HOTPLUG_BASE through intermediate variables/arguments where it's not needed. Instead initialize in module static variable when MMIO region is mapped and use that within memory_hotplug.c whenever it's required. That way MMIO base specified only at one place and AML with MMIO would always use the same value. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.

2016-01-09pc: acpi: memhp: drop not needed stringify(MEMORY_foo) usageIgor Mammedov
most of MEMORY_foo defines are not shared with ASL anymore and are used only inside of memory_hotplug_acpi_table.c, so move them there and make them strings. As result we can replace stringify(MEMORY_foo) with just MEMORY_foo, which makes code a bit cleaner. No AML change introduced by this patch.

2015-02-26pc: acpi-build: create CPU hotplug IO region dynamicallyIgor Mammedov
it replaces a static complied in DSDT MMIO region for CPU hotplug with one created at runtime leaving only truly static CPU hotplug related ASL bits in DSDT. It also puts CPU_HOTPLUG_RESOURCE_DEVICE into PCI0 scope and reserves resources from it, preparing for dropping manual hole punching in PCI0._CRS. Later it also would make easier to reuse current ACPI CPU hotplug on other targets. Also later it would be possible to move remaining CPU hotplug ASL methods into build_ssdt() and add all CPU hotplug related AML into SSDT only when CPU hotplug is enabled, further reducing ACPI tables blob if CPU hotplug isn't used. impl. detail: Windows XP can't handle /BSODs/ OperationRegion declaration in DSDT when variable from SSDT is used for specifying its address/length and also when Field declared in DSDT with OperationRegion from SSDT if DSDT is being parsed before SSDT. But it works just fine when referencing named fields from another table. Hence OperationRegion and Field declaration are moved to SSDT to make XP based editions work. PS: Later Windows editions seem to be fine with above conditions. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S.
