2015-06-15audio: expose drv_opaque to init_out and init_inKővágó, Zoltán11-20/+27
Currently the opaque pointer returned by audio_driver's init is only exposed to the driver's fini, but not to audio_pcm_ops. This way if someone wants to share a variable with the driver and the pcm, he must use global variables. This patch fixes it by adding a third parameter to audio_pcm_op's init_out and init_in.

2015-06-12rocker: bring link up/down on PHY enable/disableScott Feldman1-0/+12
When the OS driver enables/disables the port, go ahead and set the port's link status to up/down in response to the change. This more closely emulates real hardware when the PHY for the port is brought up/down and the PHY negotiates carrier (link status) with link partner. In the case of qemu, the virtual rocker device can't really do link negotiation with the link partner as that requires signally over a physical medium (the wire), so just pretend the negotiation was successful and bring the link up when the port is enabled.

In MIPS64, when CP0 destination register specified is the EntryLo0 or EntryLo1, bits 1:0 of the GPR appear at bits 31:30 of EntryLo0 or EntryLo1. This is to compensate for RI and XI, which were shifted to bits 63:62 by MTC0 to EntryLo0 or EntryLo1. Therefore creating separate functions for EntryLo0 and EntryLo1.

2015-06-12target-mips: add CP0.PageGrain.ELPA supportLeon Alrae5-12/+42
CP0.PageGrain.ELPA enables support for large physical addresses. This field is encoded as follows: 0: Large physical address support is disabled. 1: Large physical address support is enabled. If this bit is a 1, the following changes occur to coprocessor 0 registers: - The PFNX field of the EntryLo0 and EntryLo1 registers is writable and concatenated with the PFN field to form the full page frame number. - Access to optional COP0 registers with PA extension, LLAddr, TagLo is defined. P5600 can operate in 32-bit or 40-bit Physical Address Mode. Therefore if XPA is disabled (CP0.PageGrain.ELPA = 0) then assume 32-bit Address Mode. In MIPS64 assume 36 as default PABITS (when CP0.PageGrain.ELPA = 0). env->PABITS value is constant and indicates maximum PABITS available on a core, whereas env->PAMask is calculated from env->PABITS and is also affected by CP0.PageGrain.ELPA.

Extend EntryLo0, EntryLo1, LLAddr and TagLo from 32 to 64 bits in MIPS32. Introduce gen_move_low32() function which moves low 32 bits from 64-bit temp to GPR; it sign extends 32-bit value on MIPS64 and truncates on MIPS32.

2015-06-12Rename RDMA structures to make destination clearDr. David Alan Gilbert1-33/+33
RDMA has two data types that are named confusingly; RDMALocalBlock (pointed to indirectly by local_ram_blocks) RDMARemoteBlock (pointed to by block in RDMAContext) RDMALocalBlocks, as the name suggests is a data strucuture that represents the RDMAable RAM Blocks on the current side of the migration whichever that is. RDMARemoteBlocks is always the shape of the RAMBlocks on the destination, even on the destination.

2015-06-12Add a protective section footerDr. David Alan Gilbert2-0/+62
Badly formatted migration streams can go undetected or produce misleading errors due to a lock of checking at the end of sections. In particular a section that adds an extra 0x00 at the end causes what looks like a normal end of stream and thus doesn't produce any errors, and something that ends in a 0x01..0x04 kind of look like real section headers and then fail when the section parser tries to figure out which section they are. This is made worse by the choice of 0x00..0x04 being small numbers that are particularly common in normal section data. This patch adds a section footer consisting of a marker (0x7e - ~) followed by the section-id that was also sent in the header. If they mismatch then it throws an error explaining which section was being loaded.
