2020-07-10error: Eliminate error_propagate() with Coccinelle, part 1Markus Armbruster1-3/+1
When all we do with an Error we receive into a local variable is propagating to somewhere else, we can just as well receive it there right away. Convert if (!foo(..., &err)) { ... error_propagate(errp, err); ... return ... } to if (!foo(..., errp)) { ... ... return ... } where nothing else needs @err.

The "when != lbl:" is necessary to avoid transforming if (fun(args, &err)) { goto out } ... out: error_propagate(errp, err); even though other paths to label out still need the error_propagate(). For an actual example, see sclp_realize(). Without the "when strict", Coccinelle transforms vfio_msix_setup(), incorrectly. I don't know what exactly "when strict" does, only that it helps here. The match of return is narrower than what I want, but I can't figure out how to express "return where the operand doesn't use @err". For an example where it's too narrow, see vfio_intx_enable().

2020-05-15qom: Drop parameter @errp of object_property_add() & friendsMarkus Armbruster1-5/+3
The only way object_property_add() can fail is when a property with the same name already exists. Since our property names are all hardcoded, failure is a programming error, and the appropriate way to handle it is passing &error_abort. Same for its variants, except for object_property_add_child(), which additionally fails when the child already has a parent. Parentage is also under program control, so this is a programming error, too. We have a bit over 500 callers. Almost half of them pass &error_abort, slightly fewer ignore errors, one test case handles errors, and the remaining few callers pass them to their own callers. The previous few commits demonstrated once again that ignoring programming errors is a bad idea. Of the few ones that pass on errors, several violate the Error API. The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. ich9_pm_add_properties(), sparc32_ledma_realize(), sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize() are wrong that way. When the one appropriate choice of argument is &error_abort, letting users pick the argument is a bad idea. Drop parameter @errp and assert the preconditions instead. There's one exception to "duplicate property name is a programming error": the way object_property_add() implements the magic (and undocumented) "automatic arrayification". Don't drop @errp there. Instead, rename object_property_add() to object_property_try_add(), and add the obvious wrapper object_property_add().

https://github.com/patchew-project/qemu into HEAD This series removes ad hoc RAM allocation API (memory_region_allocate_system_memory) and consolidates it around hostmem backend. It allows to * resolve conflicts between global -mem-prealloc and hostmem's "policy" option, fixing premature allocation before binding policy is applied * simplify complicated memory allocation routines which had to deal with 2 ways to allocate RAM. * reuse hostmem backends of a choice for main RAM without adding extra CLI options to duplicate hostmem features. A recent case was -mem-shared, to enable vhost-user on targets that don't support hostmem backends [1] (ex: s390) * move RAM allocation from individual boards into generic machine code and provide them with prepared MemoryRegion. * clean up deprecated NUMA features which were tied to the old API (see patches) - "numa: remove deprecated -mem-path fallback to anonymous RAM" - (POSTPONED, waiting on libvirt side) "forbid '-numa node,mem' for 5.0 and newer machine types" - (POSTPONED) "numa: remove deprecated implicit RAM distribution between nodes" Introduce a new machine.memory-backend property and wrapper code that aliases global -mem-path and -mem-alloc into automatically created hostmem backend properties (provided memory-backend was not set explicitly given by user). A bulk of trivial patches then follow to incrementally convert individual boards to using machine.memory-backend provided MemoryRegion. Board conversion typically involves: * providing MachineClass::default_ram_size and MachineClass::default_ram_id so generic code could create default backend if user didn't explicitly provide memory-backend or -m options * dropping memory_region_allocate_system_memory() call * using convenience MachineState::ram MemoryRegion, which points to MemoryRegion allocated by ram-memdev On top of that for some boards: * missing ram_size checks are added (typically it were boards with fixed ram size) * ram_size fixups are replaced by checks and hard errors, forcing user to provide correct "-m" values instead of ignoring it and continuing running. After all boards are converted, the old API is removed and memory allocation routines are cleaned up.

2020-01-29hw/core/loader: Let load_elf() populate a field with CPU-specific flagsAleksandar Markovic1-1/+1
While loading the executable, some platforms (like AVR) need to detect CPU type that executable is built for - and, with this patch, this is enabled by reading the field 'e_flags' of the ELF header of the executable in question. The change expands functionality of the following functions: - load_elf() - load_elf_as() - load_elf_ram() - load_elf_ram_sym() The argument added to these functions is called 'pflags' and is of type 'uint32_t*' (that matches 'pointer to 'elf_word'', 'elf_word' being the type of the field 'e_flags', in both 32-bit and 64-bit variants of ELF header). Callers are allowed to pass NULL as that argument, and in such case no lookup to the field 'e_flags' will happen, and no information will be returned, of course.

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.

Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only 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.

Patch was originally written by Amit Singh Tomar <amit.tomar@freescale.com> see http://patchwork.ozlabs.org/patch/431475/ I only fixed it enough for application on top of current qemu master 20b084c4b1401b7f8fbc385649d48c67b6f43d44, and hopefully fixed checkpatch errors Tested by booting Linux kernel 4.20.12.

2019-02-05elf: Add optional function ptr to load_elf() to parse ELF notesLiam Merwick1-1/+2
This patch adds an optional function pointer, 'elf_note_fn', to load_elf() which causes load_elf() to additionally parse any ELF program headers of type PT_NOTE and check to see if the ELF Note is of the type specified by the 'translate_opaque' arg. If a matching ELF Note is found then the specfied function pointer is called to process the ELF note. Passing a NULL function pointer results in ELF Notes being skipped. The first consumer of this functionality is the PVHboot support which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while loading the uncompressed kernel binary in order to discover the boot entry address for the x86/HVM direct boot ABI.

2019-01-07Support u-boot noload images for arm as used by, NetBSD/evbarm GENERIC kernel.Nick Hudson1-0/+1
noload kernels are loaded with the u-boot image header and as a result the header size needs adding to the entry point. Fake up a hdr so the kernel image is loaded at the right address and the entry point is adjusted appropriately. The default location for the uboot file is 32MiB above bottom of DRAM. This matches the recommendation in Documentation/arm/Booting. Clarify the load_uimage API to state the passing of a load address when an image doesn't specify one, or when loading a ramdisk is expected. Adjust callers of load_uimage, etc. Signed-off-by: Nick Hudson <skrll@netbsd.org> Message-id: 11488a08-1fe0-a278-2210-deb64731107f@gmx.co.uk Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2018-12-21e500: simplify IRQ wiringGreg Kurz1-10/+8
The OpenPIC have 5 outputs per connected CPU. The machine init code hence needs a bi-dimensional array (smp_cpu lines, 5 columns) to wire up the irqs between the PIC and the CPUs. The current code first allocates an array of smp_cpus pointers to qemu_irq type, then it allocates another array of smp_cpus * 5 qemu_irq and fills the first array with pointers to each line of the second array. This is rather convoluted. Simplify the logic by introducing a structured type that describes all the OpenPIC outputs for a single CPU, ie, fixed size of 5 qemu_irq, and only allocate a smp_cpu sized array of those. This also allows to use g_new(T, n) instead of g_malloc(sizeof(T) * n) as recommended in HACKING. Signed-off-by: Greg Kurz <groug@kaod.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2018-05-10platform-bus-device: use device plug callback instead of machine_done notifierIgor Mammedov1-21/+17
platform-bus were using machine_done notifier to get and map (assign irq/mmio resources) dynamically added sysbus devices after all '-device' options had been processed. That however creates non obvious dependencies on ordering of machine_done notifiers and requires carefull line juggling to keep it working. For example see comment above create_platform_bus() and 'straitforward' arm_load_kernel() had to converted to machine_done notifier and that lead to yet another machine_done notifier to keep it working arm_register_platform_bus_fdt_creator(). Instead of hiding resource assignment in platform-bus-device to magically initialize sysbus devices, use device plug callback and assign resources explicitly at board level at the moment each -device option is being processed. That adds a bunch of machine declaration boiler plate to e500plat board, similar to ARM/x86 but gets rid of hidden machine_done notifier and would allow to remove the dependent notifiers in ARM code simplifying it and making code flow easier to follow.

At address 32M as a raw image and afterwards by load_elf/load_uimage at the corresponding load address. In this case the region for the device tree and the raw kernel image may overlap.

When here do not use bios_name/size for the kernel and use a more generic name called payload_name/size.

Since KVM HV only supports PAPR, not e500, it doesn't make sense to use it here.
