2022-09-13semihosting: Allow optional use of semihosting from userspacePeter Maydell1-1/+1
Currently our semihosting implementations generally prohibit use of semihosting calls in system emulation from the guest userspace. This is a very long standing behaviour justified originally "to provide some semblance of security" (since code with access to the semihosting ABI can do things like read and write arbitrary files on the host system). However, it is sometimes useful to be able to run trusted guest code which performs semihosting calls from guest userspace, notably for test code. Add a command line suboption to the existing semihosting-config option group so that you can explicitly opt in to semihosting from guest userspace with -semihosting-config userspace=on (There is no equivalent option for the user-mode emulator, because there by definition all code runs in userspace and has access to semihosting already.) This commit adds the infrastructure for the command line option and adds a bool 'is_user' parameter to the function semihosting_userspace_enabled() that target code can use to check whether it should be permitting the semihosting call for userspace. It mechanically makes all the callsites pass 'false', so they continue checking "is semihosting enabled in general". Subsequent commits will make each target that implements semihosting honour the userspace=on option by passing the correct value and removing whatever "don't do this for userspace" checking they were doing by hand.

2022-08-08vl: fix [memory] section with -readconfigPaolo Bonzini1-11/+14
The -M memory.* options do not have magic applied to them like the -m option, namely no "M" (for mebibytes) is tacked at the end of a suffixless value for "-M memory.size". This magic is performed by parse_memory_options, and we have to do it for both "-m" and the [memory] section of a config file. Storing [memory] sections directly to machine_opts_dict changed the meaning of [memory] size = "1024" in a -readconfig file from 1024MiB to 8KiB (1024 Bytes rounded up to 8KiB silently). To avoid this, the [memory] section has to be changed back to QemuOpts (combining [memory] and "-m" will work fine thanks to .merge_lists being true). Change parse_memory_options() so that, similar to the older function set_memory_options(), it operates after command line parsing is done; and also call it where set_memory_options() used to be. Note, the parsing code uses exit(1) instead of exit(EXIT_FAILURE) to match neighboring code.

After writing the PID file, we register an exit notifier to unlink it when the process terminates.

Therefore, pass the absolute path (created with realpath()) to the unlink() call in the exit notifier. (realpath() needs a path pointing to an existing file, so we cannot use it before qemu_write_pidfile().)

The bug is an uninitialized memory read, along the translate_fail path, which results in garbage being read from iotlb_to_section, which can lead to a crash in io_readx/io_writex.

2022-06-06replay: notify vCPU when BH is scheduledPavel Dovgalyuk1-0/+8
vCPU execution should be suspended when new BH is scheduled. This is needed to avoid guest timeouts caused by the long cycles of the execution. In replay mode execution may hang when vCPU sleeps and block event comes to the queue. This patch adds notification which wakes up vCPU or interrupts execution of guest code.

We have "-sdl" and "-curses", but no "-gtk" and no "-cocoa" ... these old-style options are rather confusing than helpful nowadays. Now that the deprecation period is over, let's remove them, so we get a cleaner interface (where "-display" is the only way to select the user interface).

2022-06-03ui: Switch "-display sdl" to use the QAPI parserThomas Huth2-71/+1
The "-display sdl" option still uses a hand-crafted parser for its parameters since we didn't want to drag an interface we considered somewhat flawed into the QAPI schema. Since the flaws are gone now, it's time to QAPIfy. This introduces the new "DisplaySDL" QAPI struct that is used to hold the parameters that are unique to the SDL display. The only specific parameter is currently "grab-mod" that is used to specify the required modifier keys to escape from the mouse grabbing mode.

2022-05-14introduce -audio as a replacement for -soundhwPaolo Bonzini1-3/+25
-audio is used like "-audio pa,model=sb16". It is almost as simple as -soundhw, but it reuses the -audiodev parsing machinery and attaches an audiodev to the newly-created device. The main 'feature' is that it knows about adding the codec device for model=intel-hda, and adding the audiodev to the codec device. In the future, it could be extended to support default models or builtin devices, just like -nic, or even a default backend. For now, keep it simple.

2022-05-13hw/cxl/host: Add support for CXL Fixed Memory Windows.Jonathan Cameron1-0/+47
The concept of these is introduced in [1] in terms of the description the CEDT ACPI table. The principal is more general. Unlike once traffic hits the CXL root bridges, the host system memory address routing is implementation defined and effectively static once observable by standard / generic system software. Each CXL Fixed Memory Windows (CFMW) is a region of PA space which has fixed system dependent routing configured so that accesses can be routed to the CXL devices below a set of target root bridges. The accesses may be interleaved across multiple root bridges. For QEMU we could have fully specified these regions in terms of a base PA + size, but as the absolute address does not matter it is simpler to let individual platforms place the memory regions. ExampleS: -cxl-fixed-memory-window targets.0=cxl.0,size=128G -cxl-fixed-memory-window targets.0=cxl.1,size=128G -cxl-fixed-memory-window targets.0=cxl0,targets.1=cxl.1,size=256G,interleave-granularity=2k Specifies * 2x 128G regions not interleaved across root bridges, one for each of the root bridges with ids cxl.0 and cxl.1 * 256G region interleaved across root bridges with ids cxl.0 and cxl.1 with a 2k interleave granularity. When system software enumerates the devices below a given root bridge it can then decide which CFMW to use. If non interleave is desired (or possible) it can use the appropriate CFMW for the root bridge in question. If there are suitable devices to interleave across the two root bridges then it may use the 3rd CFMS. A number of other designs were considered but the following constraints made it hard to adapt existing QEMU approaches to this particular problem. 1) The size must be known before a specific architecture / board brings up it's PA memory map. We need to set up an appropriate region. 2) Using links to the host bridges provides a clean command line interface but these links cannot be established until command line devices have been added. Hence the two step process used here of first establishing the size, interleave-ways and granularity + caching the ids of the host bridges and then, once available finding the actual host bridges so they can be used later to support interleave decoding.

2022-05-09Warn user if the vga flag is passed but no vga device is createdGautam Agrawal2-0/+8
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.

However, the uses of -writeconfig are substantially more limited, as it is generally easier to write the configuration by hand in the first place.
