2017-01-18fw-cfg: bump "x-file-slots" to 0x20 for 2.9+ machine typesLaszlo Ersek
More precisely, the "x-file-slots" count is bumped for all machine types that: (a) use fw_cfg, and (b) are not versioned (hence migration is not expected to work for them across QEMU releases anyway), or have version 2.9. This affects machine types implemented in the following source files: - "hw/arm/virt.c". The "virt-*" machine type is versioned, and the <= 2.8 versions already depend on HW_COMPAT_2_8 (see commit e353aac51b944). Therefore adding the "x-file-slots" compat values to HW_COMPAT_2_8 suffices. - "hw/i386/pc.c". The "pc-i440fx-*" (including "pc-*") and "pc-q35-*" machine types are versioned. Modifying HW_COMPAT_2_8 is sufficient here too (see commit "pc: Add 2.9 machine-types"). The "isapc" machtype is not versioned. The "xenfv" machine type, which uses fw_cfg for direct kernel booting, is also not versioned. - "hw/ppc/mac_newworld.c". The "mac99" machine type is not versioned. - "hw/ppc/mac_oldworld.c". The "g3beige" machine type is not versioned. - "hw/sparc/sun4m.c". None of the 9 machine types defined in this file appear versioned. - "hw/sparc64/sun4u.c". None of the 3 machine types defined in this file appear versioned. Cc: "Gabriel L. Somlo" <somlo@cmu.edu> Cc: "Michael S.

2017-01-18fw-cfg: turn FW_CFG_FILE_SLOTS into a device propertyLaszlo Ersek
We'd like to raise the value of FW_CFG_FILE_SLOTS. Doing it naively could lead to problems with backward migration: a more recent QEMU (running an older machine type) would allow the guest, in fw_cfg_select(), to select a high key value that is unavailable in the same machine type implemented by the older (target) QEMU. On the target host, fw_cfg_data_read() for example could dereference nonexistent entries. As first step, size the FWCfgState.entries[*] and FWCfgState.entry_order arrays dynamically. All three array sizes will be influenced by the new field FWCfgState.file_slots (and matching device property). Make the following changes: - Replace the FW_CFG_FILE_SLOTS macro with FW_CFG_FILE_SLOTS_MIN (minimum count of fw_cfg file slots) in the header file. The value remains 0x10. - Replace all uses of FW_CFG_FILE_SLOTS with a helper function called fw_cfg_file_slots(), returning the new property. - Eliminate the macro FW_CFG_MAX_ENTRY, and replace all its uses with a helper function called fw_cfg_max_entry(). - In the MMIO- and IO-mapped realize functions both, allocate all three arrays dynamically, based on the new property. - The new property defaults to FW_CFG_FILE_SLOTS_MIN. This is going to be customized in the following patches. Cc: "Gabriel L. Somlo" <somlo@cmu.edu> Cc: "Michael S.

2017-01-18vhost_net: device IOTLB supportJason Wang
This patches implements Device IOTLB support for vhost kernel. This is done through: 1) switch to use dma helpers when map/unmap vrings from vhost codes 2) introduce a set of VhostOps to: - setting up device IOTLB request callback - processing device IOTLB request - processing device IOTLB invalidation 2) kernel support for Device IOTLB API: - allow vhost-net to query the IOMMU IOTLB entry through eventfd - enable the ability for qemu to update a specified mapping of vhost - through ioctl. - enable the ability to invalidate a specified range of iova for the device IOTLB of vhost through ioctl. In x86/intel_iommu case this is triggered through iommu memory region notifier from device IOTLB invalidation descriptor processing routine. With all the above, kernel vhost_net can co-operate with userspace IOMMU. For vhost-user, the support could be easily done on top by implementing the VhostOps. Cc: Michael S.

This reverts commit aff8fd18f1786fc5af259a9bc0077727222f51ca. Both virtio-net and virtio-crypto do not balance virtio_queue_set_notification() enable and disable calls.

2017-01-18virtio-net: enable ioeventfd even if vhost=offPaolo Bonzini
virtio-net-pci does not enable ioeventfd for historical reasons (and nobody ever checked whether it should be revisited). Note that other backends do enable ioeventfd for virtio-net. However, it has a major effect on performance. On Windows, throughput is _multiplied_ by 2 or 3 on TCP_STREAM (on small packets it is "only" a 30% improvement) and a little less so on TCP_MAERTS albeit still very much statistically significant. Latency also has a single digit improvement. This is not visible when using vhost, which forces ioeventfd=on, but it is substantial without vhost. In addition, also on Windows and with the RHEL 7.3 kernel, APICv seems to slow down virtio-net performance a bit, but the penalty with this patch goes from -25% to -7%.

The recipe for making a man page from .texi is duplicated several times over. Capture it in suitable pattern rules instead.

2017-01-16build-sys: remove dvi doc generationMarc-André Lureau
There is no clear reason to have rules to generate dvi format documentation, pdf is generally better supported nowadays.

2017-01-16build-sys: use --no-split for infoMarc-André Lureau
Splitting the info files doesn't bring much benefits these days. This fixes also untracked generated info files from git ignore. Let's use MAKEINFOFLAGS for common flags, --number-sections is already the default anyway, so adding it doesn't change the info output.

2017-01-16docs: add qemu logo to pdfMarc-André Lureau
Add a logo to texi2pdf output. Other formats (info/html) are left as future improvements.

2017-01-16qapi: add qapi2texi scriptMarc-André Lureau
As the name suggests, the qapi2texi script converts JSON QAPI description into a texi file suitable for different target formats (info/man/txt/pdf/html...). It parses the following kind of blocks: Free-form: ## # = Section # == Subsection # # Some text foo with *emphasis* # 1. with a list # 2. like that # # And some code: # | $ echo foo # | -> do this # | <- get that # ## Symbol description: ## # @symbol: # # Symbol body ditto ergo sum. Foo bar # baz ding. # # @param1: the frob to frobnicate # @param2: #optional how hard to frobnicate # # Returns: the frobnicated frob. # If frob isn't frobnicatable, GenericError. # # Since: version # Notes: notes, comments can have # - itemized list # - like this # # Example: # # -> { "execute": "quit" } # <- { "return": {} } # ## That's roughly following the following EBNF grammar: api_comment = "##\n" comment "##\n" comment = freeform_comment | symbol_comment freeform_comment = { "# " text "\n" | "#\n" } symbol_comment = "# @" name ":\n" { member | tag_section | freeform_comment } member = "# @" name ':' [ text ] "\n" freeform_comment tag_section = "# " ( "Returns:", "Since:", "Note:", "Notes:", "Example:", "Examples:" ) [ text ] "\n" freeform_comment text = free text with markup Note that the grammar is ambiguous: a line "# @foo:\n" can be parsed both as freeform_comment and as symbol_comment. The actual parser recognizes symbol_comment. See docs/qapi-code-gen.txt for more details. Deficiencies and limitations: - the generated QMP documentation includes internal types - union type support is lacking - type information is lacking in generated documentation - doc comment error message positions are imprecise, they point to the beginning of the comment. - a few minor issues, all marked TODO/FIXME in the code Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <20170113144135.5150-16-marcandre.lureau@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> [test-qapi.py tweaked to avoid trailing empty lines in .out] Signed-off-by: Markus Armbruster <armbru@redhat.com>
