For example 0x81000000 satisfies this condition when ETH_ALEN is 6. Fix it by making the value unsigned. For consistency, change first_multi as well. Note: all call sites were audited to confirm that making them unsigned didn't cause any issues: it turns out we actually never do math on them, so it's easy to validate because both values are always <= MAC_TABLE_ENTRIES.

Machine types <= 2.0 will for now continue using field-by-field overrides to SeaBIOS defaults, but for machine types 2.1 and up we expect the BIOS to look for and use the aggregate tables generated by this patch.

* PPC: Clean up DECR implementationAlexander Graf2014-04-081-0/+3
| | | | | | | | | | | | | | | | | | | There are 3 different variants of the decrementor for BookE and BookS. The BookE variant sets TSR[DIS] to 1 when the DEC value becomes 1 or 0. TSR[DIS] is then the indicator whether the decrementor interrupt line is asserted or not. The old BookS variant treats DEC as an edge interrupt that gets triggered when the DEC value's top bit turns 1 from 0. The new BookS variant maintains the assertion bit inside DEC itself. Whenever the DEC value becomes negative (top bit set) the DEC interrupt line is asserted. So far we implemented mostly the old BookS variant. Let's do them all properly. This fixes booting pseries ppc64 guest images in TCG mode for me. Signed-off-by: Alexander Graf <agraf@suse.de>
* softfloat: Introduce float32_to_uint64_round_to_zeroTom Musta2014-04-081-0/+1
| | | | | | | | | | | | | | This change adds the float32_to_uint64_round_to_zero function to the softfloat library. This function fills out the complement of float32 to INT round-to-zero conversion rountines, where INT is {int32_t, uint32_t, int64_t, uint64_t}. This contribution can be licensed under either the softfloat-2a or -2b license.

* block: Fix snapshot=on for protocol parsed from filenameKevin Wolf2014-04-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | Since commit 9fd3171a, BDRV_O_SNAPSHOT uses an option QDict to specify the originally requested image as the backing file of the newly created temporary snapshot. This means that the filename is stored in "file.filename", which is an option that is not parsed for protocol names. Therefore things like -drive file=nbd:localhost:10809 were broken because it looked for a local file with the literal name 'nbd:localhost:10809'. This patch changes the way BDRV_O_SNAPSHOT works once again. We now open the originally requested image as normal, and then do a similar operation as for live snapshots to put the temporary snapshot on top. This way, both driver specific options and parsed filenames work. As a nice side effect, this results in code movement to factor bdrv_append_temp_snapshot() out. This is a good preparation for moving its call to drive_init() and friends eventually. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Max Reitz <mreitz@redhat.com>

* cpu: Avoid QOM casts for CPU()Andreas Färber2014-03-311-1/+6
| | | | | | | | | | | | | | | | | | | | | | | CPU address spaces touching load and store helpers as well as the movement of (almost) all fields from CPU_COMMON to CPUState have led to a noticeable increase of CPU() usage in "hot" paths for both TCG and KVM. While CPU()'s OBJECT_CHECK() might help detect development errors, i.e. in form of crashes due to QOM vs. non-QOM mismatches rather than QOM type mismatches, it is not really needed at runtime since mostly used in CPU-specific paths, coming from a target-specific CPU subtype. If that pointer is damaged, other errors are highly likely to occur elsewhere anyway. Keep the CPU() macro for a consistent developer experience and for flexibility to exchange its implementation, but turn it into a pure, unchecked C cast for now. Compare commit 6e42be7cd10260fd3a006d94f6c870692bf7a2c0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QEMU supports firmware names for all devices in the QEMU tree but some architectures expect some parts of firmware path names in different format. This introduces a firmware-pathname-change interface definition. If some machines needs to redefine the firmware path format, it has to add the TYPE_FW_PATH_PROVIDER interface to an object that is above the device on the QOM tree (typically /machine).
