2016-02-06ipmi: add ACPI power and GUID commandsCédric Le Goater1-0/+49
>From the specs (20.8 Get Device GUID Command), the command needs to return a GUID (Globally Unique ID), or UUID, that should never change over the lifetime of the device. qemu_uuid looked like a good candidate to start with but we could use a specific BMC property also if needed.

2016-02-06ipmi: introduce a struct ipmi_sdr_compactCédric Le Goater1-28/+44
Currently, sdr attributes are identified using byte offsets and this can be a bit confusing. This patch adds a struct ipmi_sdr_compact conforming to the IPMI specs and replaces byte offsets with names. It also introduces and uses a struct ipmi_sdr_header in sections of the code where no assumption is made on the type of SDR. This leave rooms to potential usage of other types in the future.

2016-02-06ipmi: fix SDR length valueCédric Le Goater1-6/+6
The IPMI BMC simulator populates the SDR table with a set of initial SDRs. The length of each SDR is taken from the record itself (byte 4) which does not include the size of the header. But, the full length (header + data) is required by the sdr_add_entry() routine. Signed-off-by: Cédric Le Goater <clg@fr.ibm.com> Acked-by: Michael S.

2016-02-06ipmi: replace goto by a return statementCédric Le Goater1-99/+41
Each routine using the IPMI_ADD_RSP_DATA, IPMI_CHECK_CMD_LEN or IPMI_CHECK_RESERVATION macros needs to define a goto label 'out' to handle hidden errors. Using directly a return statement has the same effect and it removes the fact that 'out' needs to be defined. The code exits in ipmi_sim_handle_command() are a little different from the rest and a "possible" error in the macro IPMI_ADD_RSP_DATA is handled before making use of it. This might be a bit excessive as a minimum response len is currently 300 bytes and the patch checks that at least 3 are available.

2016-01-22fpu: Replace int32 typedef with int32_tPeter Maydell2-2/+2
Replace the int32 softfloat-specific typedef with int32_t. This change was made with find hw include fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\bint32\b/int32_t/g' together with manual removal of the typedef definition, and manual undoing of some mis-hits where macro arguments were being used for token pasting rather than as a type. The uses in hw/ipmi/ should not have been using this type at all.
