2019-08-16sysemu: Split sysemu/runstate.h off sysemu/sysemu.hMarkus Armbruster
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related to the system-emulator. Evidence: * It's included widely: in my "build everything" tree, changing sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h, down from 5400 due to the previous two commits). * It pulls in more than a dozen additional headers. Split stuff related to run state management into its own header sysemu/runstate.h. Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400 to 4200. Touching new sysemu/runstate.h recompiles some 500 objects. Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also add qemu/main-loop.h.

2019-08-16Include hw/qdev-properties.h lessMarkus Armbruster
In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.

2019-05-23hw/nvram/fw_cfg: Store 'reboot-timeout' as little endianLi Qiang
The current codebase is not specific about the endianess of the fw_cfg 'file' entry 'reboot-timeout'. Per docs/specs/fw_cfg.txt: === All Other Data Items === Please consult the QEMU source for the most up-to-date and authoritative list of selector keys and their respective items' purpose, format and writeability. Checking the git history, this code was introduced in commit ac05f3492421, very similar to commit 3d3b8303c6f8 for the 'boot-menu-wait' entry, which explicitely use little-endian. OVMF consumes 'boot-menu-wait' as little-endian, however it does not consume 'reboot-timeout'. Regarding the git history and OVMF use, we choose to explicit 'reboot-timeout' endianess as little-endian.

2019-03-12spapr: Use CamelCase properlyDavid Gibson
The qemu coding standard is to use CamelCase for type and structure names, and the pseries code follows that... sort of. There are quite a lot of places where we bend the rules in order to preserve the capitalization of internal acronyms like "PHB", "TCE", "DIMM" and most commonly "sPAPR". That was a bad idea - it frequently leads to names ending up with hard to read clusters of capital letters, and means they don't catch the eye as type identifiers, which is kind of the point of the CamelCase convention in the first place. In short, keeping type identifiers look like CamelCase is more important than preserving standard capitalization of internal "words". So, this patch renames a heap of spapr internal type names to a more standard CamelCase. In addition to case changes, we also make some other identifier renames: VIOsPAPR* -> SpaprVio* The reverse word ordering was only ever used to mitigate the capital cluster, so revert to the natural ordering. VIOsPAPRVTYDevice -> SpaprVioVty VIOsPAPRVLANDevice -> SpaprVioVlan Brevity, since the "Device" didn't add useful information sPAPRDRConnector -> SpaprDrc sPAPRDRConnectorClass -> SpaprDrcClass Brevity, and makes it clearer this is the same thing as a "DRC" mentioned in many other places in the code This is 100% a mechanical search-and-replace patch. It will, however, conflict with essentially any and all outstanding patches touching the spapr code. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2019-03-11hw/nvram/fw_cfg: Remove the unnecessary boot_splash_filedata_sizePhilippe Mathieu-Daudé
The 'boot_splash_filedata_size' was introduced as a global variable in 3d3b8303c6f. This variable is used as a 'size' argument to the fw_cfg_add_file(). This function has an interface contract with its 'data' argument, but there is no such contract for 'size' (this is not a referenced pointer). We can simply remove it.

2019-02-05fw_cfg: fix the life cycle and the name of "qemu_extra_params_fw"Laszlo Ersek
Commit 19bcc4bc3213 ("fw_cfg: Make qemu_extra_params_fw locally", 2019-01-04) changed the storage duration of the "qemu_extra_params_fw" array from static to automatic. This broke the interface contract on the fw_cfg_add_file() function, which is documented as follows, in "include/hw/nvram/fw_cfg.h": > [...] The data referenced by the starting pointer is only linked, NOT > copied, into the data structure of the fw_cfg device. [...] As a result, when guest firmware fetches the "etc/boot-menu-wait" fw_cfg file, it now sees garbage. Fix the regression by changing the storage duration to allocated. (The call is reached at most once, on the realize path of the board-specific fw_cfg sysbus device.) While at it, clean up the name and the assignment of the object as well.

2018-08-16fw_cfg: ignore suffixes in the bootdevice list dependent on machine classMark Cave-Ayland
For the older machines (such as Mac and SPARC) the DT nodes representing bootdevices for disk nodes are irregular for mainly historical reasons. Since the majority of bootdevice nodes for these machines either do not have a separate disk node or require different (custom) names then it is much easier for processing to just disable all suffixes for a particular machine. Introduce a new ignore_boot_device_suffixes MachineClass property to control bootdevice suffix generation, defaulting to false in order to preserve compatibility.

As part of plumbing MemTxAttrs down to the IOMMU translate method, add MemTxAttrs as an argument to the MemoryRegion valid.accepts callback. We'll need this for subpage_accepts(). We could take the approach we used with the read and write callbacks and add new a new _with_attrs version, but since there are so few implementations of the accepts hook we just change them all.

2018-02-09Move include qemu/option.h from qemu-common.h to actual usersMarkus Armbruster
qemu-common.h includes qemu/option.h, but most places that include the former don't actually need the latter. Drop the include, and add it to the places that actually need it. While there, drop superfluous includes of both headers, and separate #include from file comment with a blank line. This cleanup makes the number of objects depending on qemu/option.h drop from 4545 (out of 4743) to 284 in my "build everything" tree.

2017-07-17fw_cfg: move qdev_init_nofail() from fw_cfg_init1() to callersMark Cave-Ayland
When looking to instantiate a TYPE_FW_CFG_MEM or TYPE_FW_CFG_IO device to be able to wire it up differently, it is much more convenient for the caller to instantiate the device and have the fw_cfg default files already preloaded during realize. Move fw_cfg_init1() to the end of both the fw_cfg_mem_realize() and fw_cfg_io_realize() functions so it no longer needs to be called manually when instantiating the device, and also rename it to fw_cfg_common_realize() which better describes its new purpose. Since it is now the responsibility of the machine to wire up the fw_cfg device it is necessary to introduce a object_property_add_child() call into fw_cfg_init_io() and fw_cfg_init_mem() to link the fw_cfg device to the root machine object as before. Finally with the previous change to fw_cfg_find() we can now remove the assert() preventing multiple fw_cfg devices being instantiated and replace them with a simple call to fw_cfg_find() at realize time instead. This allows us to remove FW_CFG_NAME and FW_CFG_PATH since they are no longer required.
