2022-06-08Fix 'writeable' typosPeter Maydell
We have about 30 instances of the typo/variant spelling 'writeable', and over 500 of the more common 'writable'. Standardize on the latter.

2022-05-09Warn user if the vga flag is passed but no vga device is createdGautam Agrawal
A global boolean variable "vga_interface_created"(declared in softmmu/globals.c) has been used to track the creation of vga interface. If the vga flag is passed in the command line "default_vga"(declared in softmmu/vl.c) variable is set to 0. To warn user, the condition checks if vga_interface_created is false and default_vga is equal to 0. If "-vga none" is passed, this patch will not warn the user regarding the creation of VGA device. The warning "A -vga option was passed but this machine type does not use that option; no VGA device has been created" is logged if vga flag is passed but no vga device is created. This patch has been tested for x86_64, i386, sparc, sparc64 and arm boards.

2021-12-15hw: Replace trivial drive_get_next() by drive_get()Markus Armbruster
drive_get_next() is basically a bad idea. It returns the "next" block backend of a certain interface type. "Next" means bus=0,unit=N, where subsequent calls count N up from zero, per interface type. This lets you define unit numbers implicitly by execution order. If the order changes, or new calls appear "in the middle", unit numbers change. ABI break. Hard to spot in review. A number of machines connect just one backend with drive_get_next(). Change them to use drive_get() directly. This makes the (zero) unit number explicit in the code.

2020-08-21trace: switch position of headers to what Meson requiresPaolo Bonzini
Meson doesn't enjoy the same flexibility we have with Make in choosing the include path. In particular the tracing headers are using $(build_root)/$(<D). In order to keep the include directives unchanged, the simplest solution is to generate headers with patterns like "trace/trace-audio.h" and place forwarding headers in the source tree such that for example "audio/trace.h" includes "trace/trace-audio.h". This patch is too ugly to be applied to the Makefiles now. It's only a way to separate the changes to the tracing header files from the Meson rewrite of the tracing logic.

2020-08-14nvram: Exit QEMU if NVRAM cannot contain all -prom-env dataGreg Kurz
Since commit 61f20b9dc5b7 ("spapr_nvram: Pre-initialize the NVRAM to support the -prom-env parameter"), pseries machines can pre-initialize the "system" partition in the NVRAM with the data passed to all -prom-env parameters on the QEMU command line. In this case it is assumed that all the data fits in 64 KiB, but the user can easily pass more and crash QEMU: $ qemu-system-ppc64 -M pseries $(for ((x=0;x<128;x++)); do \ echo -n " -prom-env " ; printf "%0.sx" {1..1024}; \ done) # this requires ~128 Kib malloc(): corrupted top size Aborted (core dumped) This happens because we don't check if all the prom-env data fits in the NVRAM and chrp_nvram_set_var() happily memcpy() it passed the buffer. This crash affects basically all ppc/ppc64 machine types that use -prom-env: - pseries (all versions) - g3beige - mac99 and also sparc/sparc64 machine types: - LX - SPARCClassic - SPARCbook - SS-10 - SS-20 - SS-4 - SS-5 - SS-600MP - Voyager - sun4u - sun4v Add a max_len argument to chrp_nvram_create_system_partition() so that it can check the available size before writing to memory. Since NVRAM is populated at machine init, it seems reasonable to consider this error as fatal. So, instead of reporting an error when we detect that the NVRAM is too small and adapt all machine types to handle it, we simply exit QEMU in all cases. This is still better than crashing. If someone wants another behavior, I guess this can be reworked later. Tested with: $ yes q | \ (for arch in ppc ppc64 sparc sparc64; do \ echo == $arch ==; \ qemu=${arch}-softmmu/qemu-system-$arch; \ for mach in $($qemu -M help | awk '! /^Supported/ { print $1 }'); do \ echo $mach; \ $qemu -M $mach -monitor stdio -nodefaults -nographic \ $(for ((x=0;x<128;x++)); do \ echo -n " -prom-env " ; printf "%0.sx" {1..1024}; \ done) >/dev/null; \ done; echo; \ done) Without the patch, affected machine types cause QEMU to report some memory corruption and crash: malloc(): corrupted top size free(): invalid size *** stack smashing detected ***: terminated With the patch, QEMU prints the following message and exits: NVRAM is too small. Try to pass less data to -prom-env It seems that the conditions for the crash have always existed, but it affects pseries, the machine type I care for, since commit 61f20b9dc5b7 only.

The floppy controller devices desugar their drive properties into floppy devices (since commit a92bd191a4 "fdc: Move qdev properties to FloppyDrive", v2.8.0). This involves some bad magic in fdctrl_connect_drives(), and exists for backward compatibility. The functions for boards to create floppy controller devices fdctrl_init_isa(), fdctrl_init_sysbus(), and sun4m_fdctrl_init() desugar -drive if=floppy to these floppy controller drive properties. If you use both -drive if=floppy (or its -fda / -fdb sugar) and -global isa-fdc for the same floppy device, -global silently loses the conflict, and both backends involved end up with the floppy device frontend attached, as demonstrated by iotest 172 (see commit before previous). This is wrong. Desugar -drive if=floppy straight to floppy devices instead, with helper fdctrl_init_drives(). The conflict now gets rejected cleanly: first, fdctrl_connect_drives() creates the floppy for the controller's property, then fdctrl_init_drives() attempts to create the floppy for -drive if=floppy, but fails because the unit is already in use. Output of iotest 172 changes in three ways: 1. The clash gets rejected. 2. In one test case, "info qtree" has the floppy devices swapped, and "info block" has their QOM paths swapped. This is because the floppy device for -fda now gets created after the one for -global isa-fdc.driveB. 3. The error message for -global floppy.drive=floppy0 changes. Before the patch, we set isa-fdc.driveA to -fda's block backend, then create the floppy device for it, then move the backend from isa-fdc.driveA to floppy.drive. Floppy creation fails when applying -global floppy.drive=floppy0, because floppy0 is still attached to isa-fdc. After the patch, we create the floppy for -fda, then set its drive property to floppy0. Now floppy creation succeeds, but setting the drive property fails, because -global already set it. Yes, this is exasperatingly complicated.

2020-05-15qom: Drop parameter @errp of object_property_add() & friendsMarkus Armbruster
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().

2020-01-29hw/core/loader: Let load_elf() populate a field with CPU-specific flagsAleksandar Markovic
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.
