2020-12-10scripts: kernel-doc: allow passing desired Sphinx C domain dialectMauro Carvalho Chehab
When kernel-doc is called via kerneldoc.py, there's no need to auto-detect the Sphinx version, as the Sphinx module already knows it. So, add an optional parameter to allow changing the Sphinx dialect. As kernel-doc can also be manually called, keep the auto-detection logic if the parameter was not specified. On such case, emit a warning if sphinx-build can't be found at PATH. I ended using a suggestion from Joe for using a more readable regex, instead of using a complex one with a hidden group like: m/^(\d+)\.(\d+)(?:\.?(\d+)?)/ in order to get the optional <patch> argument.

Since commit aa35ec2213b ("hw/arm/raspi: Use more specific machine names") the raspi2/raspi3 machines have been renamed as raspi2b/raspi3b. Note, rather than the raspi3b, the raspi3ap introduced in commit 5be94252d34 ("hw/arm/raspi: Add the Raspberry Pi 3 model A+") is a closer match to what QEMU models, but only provides 512 MB of RAM. As more Raspberry Pi 2/3 models are emulated, in order to avoid confusion, deprecate the raspi2/raspi3 machine aliases.

2020-11-20docs: Get rid of the weird _005f links in the man pageThomas Huth
The man page does not contain all the chapters from the System Emulation Users Guide, so some of the links that we've put into the qemu options descriptions can not be resolved and thus the link names are used in the man pages instead. These link names currently contain weird "_005f" letters in the middle and just do not make any sense for the users. To avoid this situation, replace the link names with more descriptive, natural text.

2020-11-12vhost-user: fix VHOST_USER_ADD/REM_MEM_REG truncationStefan Hajnoczi
QEMU currently truncates the mmap_offset field when sending VHOST_USER_ADD_MEM_REG and VHOST_USER_REM_MEM_REG messages. The struct layout looks like this: typedef struct VhostUserMemoryRegion { uint64_t guest_phys_addr; uint64_t memory_size; uint64_t userspace_addr; uint64_t mmap_offset; } VhostUserMemoryRegion; typedef struct VhostUserMemRegMsg { uint32_t padding; /* WARNING: there is a 32-bit hole here! */ VhostUserMemoryRegion region; } VhostUserMemRegMsg; The payload size is calculated as follows when sending the message in hw/virtio/vhost-user.c: msg->hdr.size = sizeof(msg->payload.mem_reg.padding) + sizeof(VhostUserMemoryRegion); This calculation produces an incorrect result of only 36 bytes. sizeof(VhostUserMemRegMsg) is actually 40 bytes. The consequence of this is that the final field, mmap_offset, is truncated. This breaks x86_64 TCG guests on s390 hosts. Other guest/host combinations may get lucky if either of the following holds: 1. The guest memory layout does not need mmap_offset != 0. 2. The host is little-endian and mmap_offset <= 0xffffffff so the truncation has no effect. Fix this by extending the existing 32-bit padding field to 64-bit. Now the padding reflects the actual compiler padding. This can be verified using pahole(1). Also document the layout properly in the vhost-user specification. The vhost-user spec did not document the exact layout. It would be impossible to implement the spec without looking at the QEMU source code. Existing vhost-user frontends and device backends continue to work after this fix has been applied. The only change in the wire protocol is that QEMU now sets hdr.size to 40 instead of 36. If a vhost-user implementation has a hardcoded size check for 36 bytes, then it will fail with new QEMUs. Both QEMU and DPDK/SPDK don't check the exact payload size, so they continue to work.

To repeat the rationale from the deprecation note: - this virtual machine has no specification - the Linux kernel dropped support for it 10 years ago Users are recommended to use the Malta board instead.

2020-11-02qemu-option-trace.rst.inc: Don't use option:: markupPeter Maydell
Sphinx 3.2 is pickier than earlier versions about the option:: markup, and complains about our usage in qemu-option-trace.rst: ../../docs/qemu-option-trace.rst.inc:4:Malformed option description '[enable=]PATTERN', should look like "opt", "-opt args", "--opt args", "/opt args" or "+opt args" In this file, we're really trying to document the different parts of the top-level --trace option, which qemu-nbd.rst and qemu-img.rst have already introduced with an option:: markup. So it's not right to use option:: here anyway. Switch to a different markup (definition lists) which gives about the same formatted output. (Unlike option::, this markup doesn't produce index entries; but at the moment we don't do anything much with indexes anyway, and in any case I think it doesn't make much sense to have individual index entries for the sub-parts of the --trace option.)

2020-10-30nbd: Add 'qemu-nbd -A' to expose allocation depthEric Blake
Allow the server to expose an additional metacontext to be requested by savvy clients. qemu-nbd adds a new option -A to expose the qemu:allocation-depth metacontext through NBD_CMD_BLOCK_STATUS; this can also be set via QMP when using block-export-add. qemu as client is hacked into viewing the key aspects of this new context by abusing the already-experimental x-dirty-bitmap option to collapse all depths greater than 2, which results in a tri-state value visible in the output of 'qemu-img map --output=json' (yes, that means x-dirty-bitmap is now a bit of a misnomer, but I didn't feel like renaming it as it would introduce a needless break of back-compat, even though we make no compat guarantees with x- members): unallocated (depth 0) => "zero":false, "data":true local (depth 1) => "zero":false, "data":false backing (depth 2+) => "zero":true, "data":true libnbd as client is probably a nicer way to get at the information without having to decipher such hacks in qemu as client. ;) Signed-off-by: Eric Blake <eblake@redhat.com> Message-Id: <20201027050556.269064-11-eblake@redhat.com> Reviewed-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>
2020-10-30nbd: Add new qemu:allocation-depth metadata contextEric Blake
'qemu-img map' provides a way to determine which extents of an image come from the top layer vs. inherited from a backing chain. This is useful information worth exposing over NBD. There is a proposal to add a QMP command block-dirty-bitmap-populate which can create a dirty bitmap that reflects allocation information, at which point the qemu:dirty-bitmap:NAME metadata context can expose that information via the creation of a temporary bitmap, but we can shorten the effort by adding a new qemu:allocation-depth metadata context that does the same thing without an intermediate bitmap (this patch does not eliminate the need for that proposal, as it will have other uses as well). While documenting things, remember that although the NBD protocol has NBD_OPT_SET_META_CONTEXT, the rest of its documentation refers to 'metadata context', which is a more apt description of what is actually being used by NBD_CMD_BLOCK_STATUS: the user is requesting metadata by passing one or more context names. So I also touched up some existing wording to prefer the term 'metadata context' where it makes sense. Note that this patch does not actually enable any way to request a server to enable this context; that will come in the next patch.

2020-10-30nbd: Update qapi to support exporting multiple bitmapsEric Blake
Since 'block-export-add' is new to 5.2, we can still tweak the interface; there, allowing 'bitmaps':['str'] is nicer than 'bitmap':'str'. This wires up the qapi and qemu-nbd changes to permit passing multiple bitmaps as distinct metadata contexts that the NBD client may request, but the actual support for more than one will require a further patch to the server. Note that there are no changes made to the existing deprecated 'nbd-server-add' command; this required splitting the QAPI type BlockExportOptionsNbd, which fortunately does not affect QMP introspection.

2020-10-27hw/gpio: Add GPIO model for Nuvoton NPCM7xxHavard Skinnemoen
The NPCM7xx chips have multiple GPIO controllers that are mostly identical except for some minor differences like the reset values of some registers. Each controller controls up to 32 pins. Each individual pin is modeled as a pair of unnamed GPIOs -- one for emitting the actual pin state, and one for driving the pin externally. Like the nRF51 GPIO controller, a gpio level may be negative, which means the pin is not driven, or floating.

The NPCM730 and NPCM750 chips have a single USB host port shared between a USB 2.0 EHCI host controller and a USB 1.1 OHCI host controller. This adds support for both of them. Testing notes: * With -device usb-kbd, qemu will automatically insert a full-speed hub, and the keyboard becomes controlled by the OHCI controller. * With -device usb-kbd,bus=usb-bus.0,port=1, the keyboard is directly attached to the port without any hubs, and the device becomes controlled by the EHCI controller since it's high speed capable. * With -device usb-kbd,bus=usb-bus.0,port=1,usb_version=1, the keyboard is directly attached to the port, but it only advertises itself as full-speed capable, so it becomes controlled by the OHCI controller. In all cases, the keyboard device enumerates correctly.
