* hw/arm/virt: vTPM supportEric Auger2020-03-051-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | Let the TPM TIS SYSBUS device be dynamically instantiable in ARM virt. A device tree node is dynamically created (TPM via MMIO). The TPM Physical Presence interface (PPI) is not supported. To run with the swtmp TPM emulator, the qemu command line must be augmented with: -chardev socket,id=chrtpm,path=swtpm-sock \ -tpmdev emulator,id=tpm0,chardev=chrtpm \ -device tpm-tis-device,tpmdev=tpm0 \ swtpm/libtpms command line example: swtpm socket --tpm2 -t -d --tpmstate dir=/tmp/tpm \ --ctrl type=unixio,path=swtpm-sock Signed-off-by: Eric Auger <eric.auger@redhat.com> Reviewed-by: Stefan Berger <stefanb@linux.ibm.com> Tested-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Acked-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Message-id: 20200305165149.618-7-eric.auger@redhat.com Signed-off-by: Stefan Berger <stefanb@linux.ibm.com>
* Clean up inclusion of sysemu/sysemu.hMarkus Armbruster2019-08-161-1/+0Star
| | | | | | | | | | | | | | | | | | | | | | In my "build everything" tree, changing sysemu/sysemu.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Almost a third of its inclusions are actually superfluous. Delete them. Downgrade two more to qapi/qapi-types-run-state.h, and move one from char/serial.h to char/serial.c. hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and stubs/semihost.c define variables declared in sysemu/sysemu.h without including it. The compiler is cool with that, but include it anyway. This doesn't reduce actual use much, as it's still included into widely included headers. The next commit will tackle that.

* hw/arm/sysbus-fdt: Only call match_fn callback if the type matchesEric Auger2018-11-131-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit af7d64ede0b9 (hw/arm/sysbus-fdt: Allow device matching with DT compatible value) introduced a match_fn callback which gets called for each registered combo to check whether a sysbus device can be dynamically instantiated. However the callback gets called even if the device type does not match the binding combo typename field. This causes an assert when passing "-device ramfb" to the qemu command line as vfio_platform_match() gets called on a non vfio-platform device. To fix this regression, let's change the add_fdt_node() logic so that we first check the type and if the match_fn callback is defined, then we also call it. Binding combos only requesting a type check do not define the match_fn callback.

* hw/arm/sysbus-fdt: Allow device matching with DT compatible valueEric Auger2018-10-151-14/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Up to now we have relied on the device type to identify a device tree node creation function. Since we would like the vfio-platform device to be instantiable with different compatible strings we introduce the capability to specialize the node creation depending on actual compatible value. NodeCreationPair is renamed into BindingEntry. The struct is enhanced with compat and match_fn() fields. We introduce a new matching function adapted to the vfio-platform generic device. Soon, the AMD XGBE can be instantiated with either manner, i.e.: -device vfio-amd-xgbe,host=e0900000.xgmac or using the new option line: -device vfio-platform,host=e0900000.xgmac Signed-off-by: Eric Auger <eric.auger@redhat.com> [geert: Match using compatible values in sysfs instead of user-supplied manufacturer/model options, reword] Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: Eric Auger <eric.auger@redhat.com> Tested-by: Eric Auger <eric.auger@redhat.com> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

| | | | | | | | | | | | | | | | | | When copy_properties_from_host() ignores the error for an optional property, it frees the error, but fails to reset it. Hence if two or more optional properties are missing, an assertion is triggered: util/error.c:57: error_setv: Assertion `*errp == NULL' failed. Fis this by resetting err to NULL after ignoring the error.

* arm/boot: split load_dtb() from arm_load_kernel()Igor Mammedov2018-05-101-57/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | load_dtb() depends on arm_load_kernel() to figure out place in RAM where it should be loaded, but it's not required for arm_load_kernel() to work. Sometimes it's neccesary for devices added with -device/device_add to be enumerated in DTB as well, which's lead to [1] and surrounding commits to add 2 more machine_done notifiers with non obvious ordering to make dynamic sysbus devices initialization happen in the right order. However instead of moving whole arm_load_kernel() in to machine_done, it's sufficient to move only load_dtb() into virt_machine_done() notifier and remove ArmLoadKernelNotifier/ /PlatformBusFDTNotifierParams notifiers, which saves us ~90LOC and simplifies code flow quite a bit. Later would allow to consolidate DTB generation within one function for 'mach-virt' board and make it reentrant so it could generate updated DTB in device hotplug secenarios. While at it rename load_dtb() to arm_load_dtb() since it's public now. Add additional field skip_dtb_autoload to struct arm_boot_info to allow manual DTB load later in mach-virt and to avoid touching all other boards to explicitly call arm_load_dtb(). 1) (ac9d32e hw/arm/boot: arm_load_kernel implemented as a machine init done notifier) Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Andrew Jones <drjones@redhat.com> Message-id: 1525691524-32265-4-git-send-email-imammedo@redhat.com Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
* platform-bus-device: use device plug callback instead of machine_done notifierIgor Mammedov2018-05-101-3/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster2016-03-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* vfio: Generalize region supportAlex Williamson2016-03-111-2/+2
| | | | | | | | | | | | | | | | | Both platform and PCI vfio drivers create a "slow", I/O memory region with one or more mmap memory regions overlayed when supported by the device. Generalize this to a set of common helpers in the core that pulls the region info from vfio, fills the region data, configures slow mapping, and adds helpers for comleting the mmap, enable/disable, and teardown. This can be immediately used by the PCI MSI-X code, which needs to mmap around the MSI-X vector table. This also changes VFIORegion.mem to be dynamically allocated because otherwise we don't know how the caller has allocated VFIORegion and therefore don't know whether to unreference it to destroy the MemoryRegion or not.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows the instantiation of the vfio-amd-xgbe device from the QEMU command line (-device vfio-amd-xgbe,host="<device>"). The guest is exposed with a device tree node that combines the description of both XGBE and PHY (representation supported from 4.2 onwards kernel): Documentation/devicetree/bindings/net/amd-xgbe.txt. There are 5 register regions, 6 interrupts including 4 optional edge-sensitive per-channel interrupts. Some property values are inherited from host device tree. Host device tree must feature a combined XGBE/PHY representation (>= 4.2 host kernel). 2 clock nodes (dma and ptp) also are created. It is checked those clocks are fixed on host side. AMD XGBE node creation function has a dependency on vfio Linux header and more generally node creation function for VFIO platform devices only make sense with CONFIG_LINUX so let's protect this code with #ifdef CONFIG_LINUX.
