2014-03-18ahci: fix sysbus supportRob Herring
Non-PCI AHCI support is broken due to assertion failures when trying to convert AHCIState to a PCIDevice pointer as AHCIState can have different container structs. Fix this by using the non-asserting object cast and checking the returned pointer is not NULL. The AddressSpace pointer is also being initialized to NULL and causing dma_memory_map call to fail. Fix this by initializing to address_space_memory for sysbus instances. Also correct AHCI_VMSTATE to use the correct container SysbusAHCIState for sysbus instances.

commit 9bcc80cd71892df42605e0c097d85c0237ff45d1 i386/acpi-build: allow more than 255 elements in CPON Replaces 0x1 with a smaller One constant. rebuild expected SSDT. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2014-03-18i386/acpi-build: allow more than 255 elements in CPONLaszlo Ersek
The build_ssdt() function builds a number of AML objects that are related to CPU hotplug, and whose IDs form a contiguous sequence of APIC IDs. (APIC IDs are in fact discontiguous, but this is the traditional interface: build a contiguous sequence from zero up that covers all possible APIC IDs.) These objects are: - a Processor() object for each VCPU, - a NTFY method, with one branch for each VCPU, - a CPON package with one element (hotplug status byte) for each VCPU. The build_ssdt() function currently limits the *count* of processor objects, and NTFY branches, and CPON elements, in 0xFF (see the assignment to "acpi_cpus"). This allows for an inclusive APIC ID range of [0..254]. This is incorrect, because the highest APIC ID that we otherwise allow a VCPU to take is 255. In order to extend the maximum count to 256, and the traversed APIC ID range correspondingly to [0..255]: - the Processor() objects need no change, - the NTFY method also needs no change, - the CPON package must be updated, because it is defined with a DefPackage, and the number of elements in such a package can be at most 255. We pick a DefVarPackage instead. We replace the Op byte, and the encoding of the number of elements. Compare: DefPackage := PackageOp PkgLength NumElements PackageElementList DefVarPackage := VarPackageOp PkgLength VarNumElements PackageElementList PackageOp := 0x12 VarPackageOp := 0x13 NumElements := ByteData VarNumElements := TermArg => Integer The build_append_int() function implements precisely the following TermArg encodings (a subset of what the ACPI spec describes): TermArg := DataObject DataObject := ComputationalData ComputationalData := ConstObj | ByteConst | WordConst | DWordConst directly encoded in the function, with build_append_byte(): ConstObj := ZeroOp | OneOp ZeroOp := 0x00 OneOp := 0x01 call to build_append_value(..., 1): ByteConst := BytePrefix ByteData BytePrefix := 0x0A ByteData := 0x00 - 0xFF call to build_append_value(..., 2): WordConst := WordPrefix WordData WordPrefix := 0x0B WordData := ByteData[0:7] ByteData[8:15] call to build_append_value(..., 4): DWordConst := DWordPrefix DWordData DWordPrefix := 0x0C DWordData := WordData[0:15] WordData[16:31] Signed-off-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Michael S.
