* qapi: The #optional tag is redundant, dropMarkus Armbruster2017-03-162-9/+7Star
| | | | | | | | | | | | | | | | | | | | | | | | | We traditionally mark optional members #optional in the doc comment. Before commit 3313b61, this was entirely manual. Commit 3313b61 added some automation because its qapi2texi.py relied on #optional to determine whether a member is optional. This is no longer the case since the previous commit: the only thing qapi2texi.py still does with #optional is stripping it out. We still reject bogus qapi-schema.json and six places for qga/qapi-schema.json. Thus, you can't actually rely on #optional to see whether something is optional. Yet we still make people add it manually. That's just busy-work. Drop the code to check, fix up and strip out #optional, along with all instances of #optional. To keep it out, add code to reject it, to be dropped again once the dust settles. No change to generated documentation.

* qapi: Make doc comments optional where we don't need themMarkus Armbruster2017-03-161-13/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | Since we added the documentation generator in commit 3313b61, doc comments are mandatory. That's a very good idea for a schema that needs to be documented, but has proven to be annoying for testing. Make doc comments optional again, but add a new directive { 'pragma': { 'doc-required': true } } to let a QAPI schema require them. Add test cases for the new pragma directive. While there, plug a minor hole in includ directive test coverage. Require documentation in the schemas we actually want documented: qapi-schema.json and qga/qapi-schema.json. We could probably make qapi2texi.py cope with incomplete documentation, but for now, simply make it refuse to run unless the schema has 'doc-required': true.

* | fw-cfg: bump "x-file-slots" to 0x20 for 2.9+ machine typesLaszlo Ersek2017-01-181-2/+2

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.

* | fw-cfg: turn FW_CFG_FILE_SLOTS into a device propertyLaszlo Ersek2017-01-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
