2013-09-20s390/eventfacility: Fix receive/send masksChristian Borntraeger
Currently we announce interchanged receive/send masks. This did not trigger a bug, since the sclp console has the same masks for send/receive and the Linux guest does not check the sclp mask for simple events like quiesce. With other event users like the sclp line mode console, we will have different send/receive bits. Fix it.

This interface use id and name as optional parameters, to handle the case that one image contain multiple snapshots with same name which may be '', but with different id. Adding parameter id is for historical compatiability reason, and that case is not possible in qemu's new interface for internal snapshot at block device level, but still possible in qemu-img.

2013-09-12snapshot: distinguish id and name in snapshot deleteWenchao Xia
Snapshot creation actually already distinguish id and name since it take a structured parameter *sn, but delete can't. Later an accurate delete is needed in qmp_transaction abort and blockdev-snapshot-delete-sync, so change its prototype. Also *errp is added to tip error, but return value is kepted to let caller check what kind of error happens. Existing caller for it are savevm, delvm and qemu-img, they are not impacted by introducing a new function bdrv_snapshot_delete_by_id_or_name(), which check the return value and do the operation again. Before this patch: For qcow2, it search id first then name to find the one to delete. For rbd, it search name. For sheepdog, it does nothing. After this patch: For qcow2, logic is the same by call it twice in caller. For rbd, it always fails in delete with id, but still search for name in second try, no change to user. Some code for *errp is based on Pavel's patch. Signed-off-by: Wenchao Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: Pavel Hrdina <phrdina@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2013-09-10abitypes.h: Remove incorrect ARM ABI_LLONG_ALIGNMENTPeter Maydell
The ARM EABI specifies that 64 bit integers should be 8 aligned; remove our incorrect setting of 4 alignment. This has no actual effect since it only set the alignment for the 'abi_ullong' and 'abi_llong' types, which are used only inside code which is MIPS-specific, but it will avoid problems later if we use the types elsewhere.

2013-09-06e1000: add interrupt mitigation supportVincenzo Maffione
This patch partially implements the e1000 interrupt mitigation mechanisms. Using a single QEMUTimer, it emulates the ITR register (which is the newer mitigation register, recommended by Intel) and approximately emulates RADV and TADV registers. TIDV and RDTR register functionalities are not emulated (RDTR is only used to validate RADV, according to the e1000 specs). RADV, TADV, TIDV and RDTR registers make up the older e1000 mitigation mechanism and would need a timer each to be completely emulated. However, a single timer has been used in order to reach a good compromise between emulation accuracy and simplicity/efficiency. The implemented mechanism can be enabled/disabled specifying the command line e1000-specific boolean parameter "mitigation", e.g. qemu-system-x86_64 -device e1000,mitigation=on,... ... For more information, see the Software developer's manual at http://download.intel.com/design/network/manuals/8254x_GBe_SDM.pdf. Interrupt mitigation boosts performance when the guest suffers from an high interrupt rate (i.e. receiving short UDP packets at high packet rate).

2013-09-06block: define get_block_status return valuePaolo Bonzini
Define the return value of get_block_status. Bits 0, 1, 2 and 9-62 are valid; bit 63 (the sign bit) is reserved for errors. Bits 3-8 are left for future extensions. The return code is compatible with the old is_allocated API: if a driver only returns 0 or 1 (aka BDRV_BLOCK_DATA) like is_allocated used to, clients of is_allocated will not have any change in behavior. Still, we will return more precise information in the next patches and the new definition of bdrv_is_allocated is already prepared for this.

2013-09-02exec: Split softmmu_defs.hRichard Henderson
The _cmmu helpers can be moved to exec-all.h. The helpers that are used from TCG will shortly need access to tcg_target_long so move their declarations into tcg.h. This requires minor include adjustments to all TCG backends. Reviewed-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-09-02exec: Rename USUFFIX to LSUFFIXRichard Henderson
In a following patch, there will be confusion between multiple "unsigned" suffixes; rename this one so as to imply "load". Reviewed-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-09-02exec: Reorganize the GETRA/GETPC macrosRichard Henderson
Always define GETRA; use __builtin_extract_return_addr, rather than having a special case for s390. Split GETPC_ADJ out of GETPC; use 2 universally, rather than having a special case for arm. Rename GETPC_LDST to GETRA_LDST to indicate that it does not contain the GETPC_ADJ value. Likewise with GETPC_EXT to GETRA_EXT. Perform the GETPC_ADJ adjustment inside helper_ret_ld/st. This will allow backends to pass along the "true" return address rather than the massaged GETPC value. In the meantime, double application of GETPC_ADJ does not hurt, since the call insn in all ISAs is at least 4 bytes long.

If the refcount of a refcount block is greater than one, we can at least try to repair that problem by duplicating the affected block. Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2013-09-02pseries: Add H_SET_MODE hcall to change guest exception endiannessAnton Blanchard
H_SET_MODE is used for controlling various partition settings. One of these settings is the endianness a guest takes its exceptions in. Signed-off-by: Anton Blanchard <anton@samba.org> [agraf: fix whitespace] Signed-off-by: Alexander Graf <agraf@suse.de>
