2015-02-26pc: acpi-build: generate _S[345] packages dynamicallyIgor Mammedov
Replaces template patching with packages composed using AML API. Note on behavior change: If S3 or S4 is disabled, respective packages won't be created and put into SSDT. Which saves us some space in SSDT and doesn't confuse guest OS with mangled package names as it was done originally. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.

2015-02-26acpi: introduce AML composer aml_append()Igor Mammedov
Adds for dynamic AML creation, which will be used for piecing ASL/AML primitives together and hiding from user/caller details about how nested context should be closed/packed leaving less space for mistakes and necessity to know how AML should be encoded, allowing user to concentrate on ASL representation instead. For example it will allow to create AML like this: init_aml_allocator(); ... Aml *scope = aml_scope("PCI0") Aml *dev = aml_device("PM") aml_append(dev, aml_name_decl("_ADR", aml_int(addr))) aml_append(scope, dev); ... free_aml_allocator(); Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.

hotplugged bridges don't get bsel allocated so acpi hotplug doesn't work for them anyway. OTOH adding them in ACPI creates a host of problems, e.g. they can't be hot-unplugged themselves which is surprising to users. So let's just skip these. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2015-02-26virtio: add feature checking helpersCornelia Huck

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. TODO: rationalize tcpalog memory management, and get rid of the mfre parameter. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Reviewed-by: Igor Mammedov <imammedo@redhat.com>
2015-02-26acpi: has_immutable_rsdp->!rsdp_in_ramMichael S. Tsirkin

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>
2015-02-26exec: round up size on MR resizeMichael S. Tsirkin
Block size must fundamentally be a multiple of target page size. Aligning automatically removes need to worry about the alignment from callers. Note: the only caller of qemu_ram_resize (acpi) already happens to have size padded to a power of 2, but we would like to drop the padding in ACPI core, and don't want to expose target page size knowledge to ACPI.

2015-02-26pc: acpi-build: migrate RSDP tableIgor Mammedov
Makes sure that RSDP stays the same /i.e. matches ACPI tables blob in source/ if guest is migrated during RSDP reading or has been already shadowed by firmware. Fix applies only to new machine types starting from 2.3, so it won't break migration for old machine types. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.
