2016-03-18qapi: Make c_type() more OO-likeEric Blake
QAPISchemaType.c_type() is a bit awkward: it takes two optional boolean flags is_param and is_unboxed, and they should never both be True. Add a new method for each of the flags, and drop the flags from c_type(). Most callers pass no flags; they remain unchanged. One caller passes is_param=True; call the new .c_param_type() instead. One caller passes is_unboxed=True, except for simple union types. This is actually an ugly special case that will go away soon, so until then, we now have to call either .c_type() or the new .c_unboxed_type(). Tolerable in the interim. It requires slightly more Python, but is arguably easier to read.

2016-03-18qapi: Fix command with named empty argument typeEric Blake
The generator special-cased { 'command':'foo', 'data': {} } to avoid emitting a visitor variable, but failed to see that { 'struct':'NamedEmptyType, 'data': {} } { 'command':'foo', 'data':'NamedEmptyType' } needs the same treatment. There, the generator happily generates a visitor to get no arguments, and a visitor to destroy no arguments; and the compiler isn't happy with that, as demonstrated by the updated qapi-schema-test.json: tests/test-qmp-marshal.c: In function ‘qmp_marshal_user_def_cmd0’: tests/test-qmp-marshal.c:264:14: error: variable ‘v’ set but not used [-Werror=unused-but-set-variable] Visitor *v; ^ No change to generated code except for the testsuite addition.

2016-03-18qapi: Assert in places where variants are not handledEric Blake
We are getting closer to the point where we could use one union as the base or variant type within another union type (as long as there are no collisions between any possible combination of member names allowed across all discriminator choices). But until we get to that point, it is worth asserting that variants are not present in places where we are not prepared to handle them: when exploding a type into a parameter list, we do not expect variants. The qapi.py code is already checking this, via the older check_type() method; but someday we hope to get rid of that and move checking into QAPISchema*.check(). The two asserts added here make sure any refactoring still catches problems, and makes it locally obvious why we can iterate over only type.members without worrying about type.variants.

2016-03-17blockdev: Split monitor reference from BB creationMax Reitz
Before this patch, blk_new() automatically assigned a name to the new BlockBackend and considered it referenced by the monitor. This patch removes the implicit monitor_add_blk() call from blk_new() (and consequently the monitor_remove_blk() call from blk_delete(), too) and thus blk_new() (and related functions) no longer take a BB name argument. In fact, there is only a single point where blk_new()/blk_new_open() is called and the new BB is monitor-owned, and that is in blockdev_init(). Besides thus relieving us from having to invent names for all of the BBs we use in qemu-img, this fixes a bug where qemu cannot create a new image if there already is a monitor-owned BB named "image". If a BB and its BDS tree are created in a single operation, as of this patch the BDS tree will be created before the BB is given a name (whereas it was the other way around before). This results in minor change to the output of iotest 087, whose reference output is amended accordingly. Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2016-03-17blockdev: Separate BB name managementMax Reitz
Introduce separate functions (monitor_add_blk() and monitor_remove_blk()) which set or unset a BB name. Since the name is equivalent to the monitor's reference to a BB, adding a name the same as declaring the BB to be monitor-owned and removing it revokes this status, hence the function names.

2016-03-17blockdev: Rename blk_backendsMax Reitz

2016-03-17block: Drop BB name from bad option errorMax Reitz
The information which BB is concerned does not seem useful enough to justify its existence in most other place (which may be related to qemu printing the -drive parameter in question anyway, and for blockdev-add the attribution is naturally unambiguous). Furthermore, as of a future patch, bdrv_get_device_name(bs) will always return the empty string before bdrv_open_inherit() returns. Therefore, just dropping that information seems to be the best course of action. Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2016-03-17qapi: Drop QERR_UNKNOWN_BLOCK_FORMAT_FEATUREMax Reitz
Just specifying a custom string is simpler in basically all places that used it, and in addition, specifying the BB or node name is something we generally do not do in other error messages when opening a BDS, so we should not do it here. This changes the output for iotest 036 (to the better, in my opinion), so the reference output needs to be changed accordingly.

2016-03-17Revert "qed: Implement .bdrv_drain"Stefan Hajnoczi
This reverts commit df9a681dc9ad41c9cdeb9ecc5d060ba9abd27e01. Note that commit df9a681dc9ad41c9cdeb9ecc5d060ba9abd27e01 included some unrelated hunks, possibly due to a merge failure or an overlooked squash. This only reverts the qed .bdrv_drain() implementation. The qed .bdrv_drain() implementation is unsafe and can lead to a double request completion. Paolo Bonzini reports: "The problem is that bdrv_qed_drain calls qed_plug_allocating_write_reqs unconditionally, but this is not correct if an allocating write is queued. In this case, qed_unplug_allocating_write_reqs will restart the allocating write and possibly cause it to complete. The aiocb however is still in use for the L2/L1 table writes, and will then be completed again as soon as the table writes are stable." For QEMU 2.6 we can simply revert this commit. A full solution for the qed need check timer may be added if the bdrv_drain() implementation is extended.

2016-03-16sd: Fix "info qtree" on boards with SD cardsPeter Maydell
The SD card object is not a SysBusDevice, so don't create it with qdev_create() if we're not assigning it to a specific bus; use object_new() instead. This was causing 'info qtree' to segfault on boards with SD cards, because qdev_create(NULL, TYPE_FOO) puts the created object on the system bus, and then we may try to run functions like sysbus_dev_print() on it, which fail when casting the object to SysBusDevice.

2016-03-16hw/arm: Add palmetto-bmc machineAndrew Jeffery
The new machine is a thin layer over the AST2400 ARM926-based SoC[1]. Between the minimal machine and the current SoC implementation there is enough functionality to boot an aspeed_defconfig Linux kernel to userspace. Nothing yet is specific to the Palmetto's BMC (other than using an AST2400 SoC), but creating specific machine types is preferable to a generic machine that doesn't match any particular hardware.

2016-03-16hw/arm: Add ASPEED AST2400 SoC modelAndrew Jeffery
While the ASPEED AST2400 SoC[1] has a broad range of capabilities this implementation is minimal, comprising an ARM926 processor, ASPEED VIC and timer devices, and a 8250 UART.
