The new format is rbd:pool/image[@snapshot][:option1=value1[:option2=value2...]] Each option is used to configure rados, and may be any Ceph option, or "conf". The "conf" option specifies a Ceph configuration file to read. This allows rbd volumes from more than one Ceph cluster to be used by specifying different monitor addresses, as well as having different logging levels or locations for different volumes.

librbd stacks on top of librados to provide access to rbd images. Using librbd simplifies the qemu code, and allows qemu to use new versions of the rbd format with few (if any) changes.

BM_STATUS_INT is automatically set during ide_set_irq(), there's no reason to set it manually in addition. There is even one case where the interrupt status bit was set, but no IRQ was raised. This is when the PRD table was reached but there is more data to transfer. The correct behaviour for this case is not to set BM_STATUS_INT. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

This patch adds a dummy legacy ISA device whose responsibility is to deploy sgabios, an option rom for a serial graphics adapter. The proposal is that this device is always-on when -nographics, but can otherwise be enable in any setup when -device sga is used.

This allows a JSON_ERROR state to be passed to the streamer to force a flush of the current tokens and pass a NULL token list to the parser rather that have it churn on bad data. (Alternatively we could just not pass it to the parser at all, but it may be useful to push there errors up the stack. NULL token lists are not currently handled by the parser, the next patch will address that) Signed-off-by: NMichael Roth <mdroth@linux.vnet.ibm.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

Currently when we reach an error state we effectively flush everything fed to the lexer, which can put us in a state where we keep feeding tokens into the parser at arbitrary offsets in the stream. This makes it difficult for the lexer/tokenizer/parser to get back in sync when bad input is made by the client. With these changes we emit an error state/token up to the tokenizer as soon as we reach an error state, and continue processing any data passed in rather than bailing out. The reset token will be used to reset the tokenizer and parser, such that they'll recover state as soon as the lexer begins generating valid token sequences again. We also map chr(192,193,245-255) to an error state here, since they are invalid UTF-8 characters. QMP guest proxy/agent will use chr(255) to force a flush/reset of previous input for reliable delivery of certain events, so also we document that thoroughly here.

Currently we flush the lexer by passing in a NULL character. This generally forces the lexer to go to the corresponding TERMINAL() state for whatever token type it is currently parsing, emits the token to the parser, then puts the lexer back into IN_START state. However, since a NULL character causes char_consumed to be 0, we always do a second pass after this, which puts us in the IN_ERROR state. Fix this behavior by adding a "flush" flag that tells the lexer not to do a more than 1 iteration.

Commit 85097db6 changed the timing when kvm_allowed is set until after kvm is initialized. During initialization, the ioeventfd initialization code checks kvm_enabled() and after this change, ioeventfd is effectively disabled. This causes a significant regression in performance.

When compiling with DEBUG_TCGV enabled, make the TCGv_ptr type distinct from TCGv_i32/TCGv_i64. This means that using an i32 or i64 TCG op to manipulate a TCGv_ptr will always be detected at compile time, rather than only if compiling on a host system with the other word size. NB: the tcg_add_ptr and tcg_sub_ptr macros have been removed as they were not used anywhere.

The prototypes for the ld/st functions on a 64 bit host declared the address parameter as a TCGv_i64 rather than a TCGv_ptr. This worked OK (since the two are aliases), but needs to be fixed to allow extension of TCG type debugging to i64/i32/ptr mismatches.
