2018-06-15exec.c: Handle IOMMUs in address_space_translate_for_iotlb()Peter Maydell2-1/+5
Currently we don't support board configurations that put an IOMMU in the path of the CPU's memory transactions, and instead just assert() if the memory region fonud in address_space_translate_for_iotlb() is an IOMMUMemoryRegion. Remove this limitation by having the function handle IOMMUs. This is mostly straightforward, but we must make sure we have a notifier registered for every IOMMU that a transaction has passed through, so that we can flush the TLB appropriately when any of the IOMMUs change their mappings.

2018-06-15iommu: Add IOMMU index argument to notifier APIsPeter Maydell1-1/+6
Add support for multiple IOMMU indexes to the IOMMU notifier APIs. When initializing a notifier with iommu_notifier_init(), the caller must pass the IOMMU index that it is interested in. When a change happens, the IOMMU implementation must pass memory_region_notify_iommu() the IOMMU index that has changed and that notifiers must be called for. IOMMUs which support only a single index don't need to change. Callers which only really support working with IOMMUs with a single index can use the result of passing MEMTXATTRS_UNSPECIFIED to memory_region_iommu_attrs_to_index().

2018-06-15bswap: Add new stn_*_p() and ldn_*_p() memory access functionsPeter Maydell2-0/+56
There's a common pattern in QEMU where a function needs to perform a data load or store of an N byte integer in a particular endianness. At the moment this is handled by doing a switch() on the size and calling the appropriate ld*_p or st*_p function for each size. Provide a new family of functions ldn_*_p() and stn_*_p() which take the size as an argument and do the switch() themselves.

2018-06-15hw/core/or-irq: Support more than 16 inputs to an OR gatePeter Maydell1-1/+4
For the IoTKit MPC support, we need to wire together the interrupt outputs of 17 MPCs; this exceeds the current value of MAX_OR_LINES. Increase MAX_OR_LINES to 32 (which should be enough for anyone). The tricky part is retaining the migration compatibility for existing OR gates; we add a subsection which is only used for larger OR gates, and define it such that we can freely increase MAX_OR_LINES in future (or even move to a dynamically allocated levels[] array without an upper size limit) without breaking compatibility.

2018-06-15block: Fix -blockdev for certain non-string scalarsMarkus Armbruster1-0/+1
Configuration flows through the block subsystem in a rather peculiar way. Configuration made with -drive enters it as QemuOpts. Configuration made with -blockdev / blockdev-add enters it as QAPI type BlockdevOptions. The block subsystem uses QDict, QemuOpts and QAPI types internally. The precise flow is next to impossible to explain (I tried for this commit message, but gave up after wasting several hours). What I can explain is a flaw in the BlockDriver interface that leads to this bug: $ qemu-system-x86_64 -blockdev node-name=n1,driver=nfs,server.type=inet,server.host=localhost,path=/foo/bar,user=1234 qemu-system-x86_64: -blockdev node-name=n1,driver=nfs,server.type=inet,server.host=localhost,path=/foo/bar,user=1234: Internal error: parameter user invalid QMP blockdev-add is broken the same way. Here's what happens. The block layer passes configuration represented as flat QDict (with dotted keys) to BlockDriver methods .bdrv_file_open(). The QDict's members are typed according to the QAPI schema. nfs_file_open() converts it to QAPI type BlockdevOptionsNfs, with qdict_crumple() and a qobject input visitor. This visitor comes in two flavors. The plain flavor requires scalars to be typed according to the QAPI schema. That's the case here. The keyval flavor requires string scalars. That's not the case here. nfs_file_open() uses the latter, and promptly falls apart for members @user, @group, @tcp-syn-count, @readahead-size, @page-cache-size, @debug. Switching to the plain flavor would fix -blockdev, but break -drive, because there the scalars arrive in nfs_file_open() as strings. The proper fix would be to replace the QDict by QAPI type BlockdevOptions in the BlockDriver interface. Sadly, that's beyond my reach right now. Next best would be to fix the block layer to always pass correctly typed QDicts to the BlockDriver methods. Also beyond my reach. What I can do is throw another hack onto the pile: have nfs_file_open() convert all members to string, so use of the keyval flavor actually works, by replacing qdict_crumple() by new function qdict_crumple_for_keyval_qiv(). The pattern "pass result of qdict_crumple() to qobject_input_visitor_new_keyval()" occurs several times more: * qemu_rbd_open() Same issue as nfs_file_open(), but since BlockdevOptionsRbd has only string members, its only a latent bug. Fix it anyway. * parallels_co_create_opts(), qcow_co_create_opts(), qcow2_co_create_opts(), bdrv_qed_co_create_opts(), sd_co_create_opts(), vhdx_co_create_opts(), vpc_co_create_opts() These work, because they create the QDict with qemu_opts_to_qdict_filtered(), which creates only string scalars. The function sports a TODO comment asking for better typing; that's going to be fun. Use qdict_crumple_for_keyval_qiv() to be safe.

2018-06-15block: Add block-specific QDict headerMax Reitz2-17/+32
There are numerous QDict functions that have been introduced for and are used only by the block layer. Move their declarations into an own header file to reflect that. While qdict_extract_subqdict() is in fact used outside of the block layer (in util/qemu-config.c), it is still a function related very closely to how the block layer works with nested QDicts, namely by sometimes flattening them. Therefore, its declaration is put into this header as well and util/qemu-config.c includes it with a comment stating exactly which function it needs.

Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link, says whether a reference must be released when the property is destroyed. This can lead to leaks if the property was later set_link(), as the added reference is never released.

The 6522 VIA timer frequency cannot be set by altering registers within the device itself and hence it is a fixed property of the machine. Move the initialisation of the timer frequency to the mos6522 reset function and ensure that any subclasses always call the parent reset function so that it isn't required to store the timer frequency within vmstate_mos6522_timer itself. By moving the frequency initialisation to the device reset function then we find that the realize function for both mos6522 and mos6522_cuda becomes obsolete and can simply be removed.

2018-06-12cuda: embed mos6522_cuda device directly rather than using QOM object linkMark Cave-Ayland2-15/+14
Examining the migration stream it can be seen that the mos6522 device state is being stored separately rather than as part of the CUDA device which is incorrect (and likely to cause issues if another mos6522 device is added to the machine). Resolve this by embedding the mos6522_cuda device directly within the CUDA device rather than using a QOM object link to reference the device separately. Note that we also bump the version in vmstate_cuda to reflect this change: this isn't particularly important for the moment as the Mac machine migration isn't 100% reliable due to issues migrating the timebase under TCG.

At the same time, users outside of block.c probably do not need to make use of the reopen functionality, so rename the current function to bdrv_is_writable_after_reopen() create a new bdrv_is_writable() function that just passes NULL to it for the reopen queue.

For qemu-io, a function returns an integer with two possible values: 0 for "qemu-io may continue execution", or 1 for "qemu-io should exit". However, there is only a single command that returns 1, and that is "quit". So let's turn this case into a global variable instead so we can make better use of the return value in a later patch.

2018-06-08arm_gicv3_kvm: kvm_dist_get/put: skip the registers banked by GICRShannon Zhao1-0/+1
While we skip the GIC_INTERNAL irqs, we don't change the register offset accordingly. This will overlap the GICR registers value and leave the last GIC_INTERNAL irq's registers out of update. Fix this by skipping the registers banked by GICR. Also for migration compatibility if the migration source (old version qemu) doesn't send gicd_no_migration_shift_bug = 1 to destination, then we shift the data of PPI to get the right data for SPI.
