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.

2015-02-26acpi: include PkgLength size only when requestedIgor Mammedov
Named/Reserved{Field} definition uses PkgLength [1] encoding to specify field length, however it doesn't include size of PkgLength field itself, while other block objects that have explicit length of its body account for PkgLength size while encoding it [2]. This special casing isn't mentioned in ACPI spec, but that's what 'iasl' compiles NamedField to so add extra argument to build_prepend_pkg_length() to allow it handle the case. -- 1.

2015-02-26acpi-build: simplify rsdp management for legacyMichael S. Tsirkin
For legacy machine types, rsdp is not in RAM, so we need a copy of rsdp for fw cfg. We previously used g_array_free with false parameter, but this seems to confuse people. This also wastes a bit of memory as the buffer is unused for new machine types. Let's just use plain g_memdup, and free original memory together with the array.

2015-02-26acpi-build: fix ACPI RAM managementMichael S. Tsirkin
This fixes multiple issues around ACPI RAM management: RSDP and linker RAM aren't currently marked dirty on update, so they won't be migrated correctly. Let's handle all tables in the same way: set correct size (assert if too big), update, mark RAM dirty. This also drops assert checking that table size didn't change: table size is fundamentally dynamic and depends on hw configuration, just set the correct size and use that (memory core asserts if size is too large). This also means we can drop tracking table size, memory core does this for us now. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
