2020-09-09hw/riscv: microchip_pfsoc: Hook GPIO controllersBin Meng
Microchip PolarFire SoC integrates 3 GPIOs controllers. It seems enough to create unimplemented devices to cover their register spaces at this point. With this commit, QEMU can boot to U-Boot (2nd stage bootloader) all the way to the Linux shell login prompt, with a modified HSS (1st stage bootloader).

2020-09-09hw/riscv: microchip_pfsoc: Connect 2 Cadence GEMsBin Meng
Microchip PolarFire SoC integrates 2 Candence GEMs to provide IEEE 802.3 standard-compliant 10/100/1000 Mbps ethernet interface. On the Icicle Kit board, GEM0 connects to a PHY at address 8 while GEM1 connects to a PHY at address 9. The 2nd stage bootloader (U-Boot) is using GEM1 by default, so we must specify 2 '-nic' options from the command line in order to get a working ethernet.

2020-09-09hw/riscv: microchip_pfsoc: Connect a Cadence SDHCI controller and an SD cardBin Meng
Microchip PolarFire SoC integrates one Cadence SDHCI controller. On the Icicle Kit board, one eMMC chip and an external SD card connect to this controller depending on different configuration. As QEMU does not support eMMC yet, we just emulate the SD card configuration. To test this, the Hart Software Services (HSS) should choose the SD card configuration: $ cp boards/icicle-kit-es/def_config.sdcard .config $ make BOARD=icicle-kit-es The SD card image can be built from the Yocto BSP at: https://github.com/polarfire-soc/meta-polarfire-soc-yocto-bsp Note the generated SD card image should be resized before use: $ qemu-img resize /path/to/sdcard.img 4G Launch QEMU with the following command: $ qemu-system-riscv64 -nographic -M microchip-icicle-kit -sd sdcard.img Signed-off-by: Bin Meng <bin.meng@windriver.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Message-Id: <1598924352-89526-9-git-send-email-bmeng.cn@gmail.com> Signed-off-by: Alistair Francis <alistair.francis@wdc.com>

2020-09-08qom: provide convenient macros for declaring and defining typesDaniel P. Berrangé
When creating new QOM types, there is a lot of boilerplate code that must be repeated using a standard pattern. This is tedious to write and liable to suffer from subtle inconsistencies. Thus it would benefit from some simple automation. QOM was loosely inspired by GLib's GObject, and indeed GObject suffers from the same burden of boilerplate code, but has long provided a set of macros to eliminate this burden in the source implementation. More recently it has also provided a set of macros to eliminate this burden in the header declaration. In GLib there are the G_DECLARE_* and G_DEFINE_* family of macros for the header declaration and source implementation respectively: https://developer.gnome.org/gobject/stable/chapter-gobject.html https://developer.gnome.org/gobject/stable/howto-gobject.html This patch takes inspiration from GObject to provide the equivalent functionality for QOM. In the header file, instead of: typedef struct MyDevice MyDevice; typedef struct MyDeviceClass MyDeviceClass; G_DEFINE_AUTOPTR_CLEANUP_FUNC(MyDeviceClass, object_unref) #define MY_DEVICE_GET_CLASS(void *obj) \ OBJECT_GET_CLASS(MyDeviceClass, obj, TYPE_MY_DEVICE) #define MY_DEVICE_CLASS(void *klass) \ OBJECT_CLASS_CHECK(MyDeviceClass, klass, TYPE_MY_DEVICE) #define MY_DEVICE(void *obj) OBJECT_CHECK(MyDevice, obj, TYPE_MY_DEVICE) struct MyDeviceClass { DeviceClass parent_class; }; We now have OBJECT_DECLARE_SIMPLE_TYPE(MyDevice, my_device, MY_DEVICE, DEVICE) In cases where the class needs some virtual methods, it can be left to be implemented manually using OBJECT_DECLARE_TYPE(MyDevice, my_device, MY_DEVICE) Note that these macros are including support for g_autoptr() for the object types, which is something previously only supported for variables declared as the base Object * type. Meanwhile in the source file, instead of: static void my_device_finalize(Object *obj); static void my_device_class_init(ObjectClass *oc, void *data); static void my_device_init(Object *obj); static const TypeInfo my_device_info = { .parent = TYPE_DEVICE, .name = TYPE_MY_DEVICE, .instance_size = sizeof(MyDevice), .instance_init = my_device_init, .instance_finalize = my_device_finalize, .class_size = sizeof(MyDeviceClass), .class_init = my_device_class_init, }; static void my_device_register_types(void) { type_register_static(&my_device_info); } type_init(my_device_register_types); We now have OBJECT_DEFINE_TYPE(MyDevice, my_device, MY_DEVICE, DEVICE) Or, if a class needs to implement interfaces: OBJECT_DEFINE_TYPE_WITH_INTERFACES(MyDevice, my_device, MY_DEVICE, DEVICE, { TYPE_USER_CREATABLE }, { NULL }) Or, if a class needs to be abstract OBJECT_DEFINE_ABSTRACT_TYPE(MyDevice, my_device, MY_DEVICE, DEVICE) IOW, in both cases the maintainer now only has to think about the interesting part of the code which implements useful functionality and avoids much of the boilerplate.

2020-09-08spapr, spapr_numa: handle vcpu ibm,associativityDaniel Henrique Barboza

This also changes the size of the of property itself, which is being represented in index 0 of numa_assoc_array[cpu->node_id], and defaults to MAX_DISTANCE_REF_POINTS for all cases but vcpus. All this logic makes more sense in spapr_numa.c, where we handle everything NUMA and associativity. A new helper spapr_numa_fixup_cpu_dt() was added, and spapr.c uses it the same way as it was using the former spapr_fixup_cpu_numa_dt().

2020-09-08spapr: introduce SpaprMachineState::numa_assoc_arrayDaniel Henrique Barboza
The next step to centralize all NUMA/associativity handling in the spapr machine is to create a 'one stop place' for all things ibm,associativity. This patch introduces numa_assoc_array, a 2 dimensional array that will store all ibm,associativity arrays of all NUMA nodes. This array is initialized in a new spapr_numa_associativity_init() function, called in spapr_machine_init(). It is being initialized with the same values used in other ibm,associativity properties around spapr files (i.e. all zeros, last value is node_id). The idea is to remove all hardcoded definitions and FDT writes of ibm,associativity arrays, doing instead a call to the new helper spapr_numa_write_associativity_dt() helper, that will be able to write the DT with the correct values. We'll start small, handling the trivial cases first. The remaining instances of ibm,associativity will be handled next.

2020-09-08ppc: introducing spapr_numa.c NUMA code helperDaniel Henrique Barboza
We're going to make changes in how spapr handles all ibm,associativity* related properties to enhance our current NUMA support. At this moment we have associativity code scattered all around spapr_* files, with hardcoded values and array sizes. This makes it harder to change any NUMA specific parameters in the future. Having everything in the same place allows not only for easier tuning, but also easier understanding since all NUMA related code is on the same file. This patch introduces a new file to gather all NUMA/associativity handling code in spapr, spapr_numa.c. To get things started, let's remove associativity-reference-points and max-associativity-domains code from spapr_dt_rtas() to a new helper called spapr_numa_write_rtas_dt(). This will decouple spapr_dt_rtas() from the NUMA changes that are going to happen in those two properties.

2020-09-08target/arm: Move start-powered-off property to generic CPUStateThiago Jung Bauermann
There are other platforms which also have CPUs that start powered off, so generalize the start-powered-off property so that it can be used by them. Note that ARMv7MState also has a property of the same name but this patch doesn't change it because that class isn't a subclass of CPUState so it wouldn't be a trivial change. This change should not cause any change in behavior.

2020-09-08spapr, spapr_nvdimm: fold NVDIMM validation in the same placeDaniel Henrique Barboza
NVDIMM has different contraints and conditions than the regular DIMM and we'll need to add at least one more. Instead of relying on 'if (nvdimm)' conditionals in the body of spapr_memory_pre_plug(), use the existing spapr_nvdimm_validate_opts() and put all NVDIMM handling code there. Rename it to spapr_nvdimm_validate() to reflect that the function is now checking more than the nvdimm device options. This makes spapr_memory_pre_plug() a bit easier to follow, and we can tune in NVDIMM parameters and validation in the same place.

2020-09-08spapr/xive: Add a 'hv-prio' property to represent the KVM escalation priorityCédric Le Goater
On POWER9, the KVM XIVE device uses priority 7 for the escalation interrupts. On POWER10, the host can use a reduced set of priorities and KVM will configure the escalation priority to a lower number. In any case, the guest is allowed to use priorities in a single range : [ 0 .. (maxprio - 1) ]. Introduce a 'hv-prio' property to represent the escalation priority number and use it to compute the "ibm,plat-res-int-priorities" property defining the priority ranges reserved by the hypervisor.

2020-09-07block: Leave BDS.backing_{file,format} constantMax Reitz
Parts of the block layer treat BDS.backing_file as if it were whatever the image header says (i.e., if it is a relative path, it is relative to the overlay), other parts treat it like a cache for bs->backing->bs->filename (relative paths are relative to the CWD). Considering bs->backing->bs->filename exists, let us make it mean the former. Among other things, this now allows the user to specify a base when using qemu-img to commit an image file in a directory that is not the CWD (assuming, everything uses relative filenames). Before this patch: $ ./qemu-img create -f qcow2 foo/bot.qcow2 1M $ ./qemu-img create -f qcow2 -b bot.qcow2 foo/mid.qcow2 $ ./qemu-img create -f qcow2 -b mid.qcow2 foo/top.qcow2 $ ./qemu-img commit -b mid.qcow2 foo/top.qcow2 qemu-img: Did not find 'mid.qcow2' in the backing chain of 'foo/top.qcow2' $ ./qemu-img commit -b foo/mid.qcow2 foo/top.qcow2 qemu-img: Did not find 'foo/mid.qcow2' in the backing chain of 'foo/top.qcow2' $ ./qemu-img commit -b $PWD/foo/mid.qcow2 foo/top.qcow2 qemu-img: Did not find '[...]/foo/mid.qcow2' in the backing chain of 'foo/top.qcow2' After this patch: $ ./qemu-img commit -b mid.qcow2 foo/top.qcow2 Image committed. $ ./qemu-img commit -b foo/mid.qcow2 foo/top.qcow2 qemu-img: Did not find 'foo/mid.qcow2' in the backing chain of 'foo/top.qcow2' $ ./qemu-img commit -b $PWD/foo/mid.qcow2 foo/top.qcow2 Image committed. With this change, bdrv_find_backing_image() must look at whether the user has overridden a BDS's backing file. If so, it can no longer use bs->backing_file, but must instead compare the given filename against the backing node's filename directly. Note that this changes the QAPI output for a node's backing_file. We had very inconsistent output there (sometimes what the image header said, sometimes the actual filename of the backing image). This inconsistent output was effectively useless, so we have to decide one way or the other. Considering that bs->backing_file usually at runtime contained the path to the image relative to qemu's CWD (or absolute), this patch changes QAPI's backing_file to always report the bs->backing->bs->filename from now on. If you want to receive the image header information, you have to refer to full-backing-filename. This necessitates a change to iotest 228. The interesting information it really wanted is the image header, and it can get that now, but it has to use full-backing-filename instead of backing_file. Because of this patch's changes to bs->backing_file's behavior, we also need some reference output changes. Along with the changes to bs->backing_file, stop updating BDS.backing_format in bdrv_backing_attach() as well. This way, ImageInfo's backing-filename and backing-filename-format fields will represent what the image header says and nothing else. iotest 245 changes in behavior: With the backing node no longer overriding the parent node's backing_file string, you can now omit the @backing option when reopening a node with neither a default nor a current backing file even if it used to have a backing node at some point. 273 also changes: The base image is opened without a format layer, so ImageInfo.backing-filename-format used to report "file" for the base image's overlay after blockdev-snapshot. However, the image header never says "file" anywhere, so it now reports $IMGFMT. Signed-off-by: Max Reitz <mreitz@redhat.com>

2020-09-07block: Add bdrv_supports_compressed_writes()Max Reitz
Filters cannot compress data themselves but they have to implement .bdrv_co_pwritev_compressed() still (or they cannot forward compressed writes). Therefore, checking whether bs->drv->bdrv_co_pwritev_compressed is non-NULL is not sufficient to know whether the node can actually handle compressed writes. This function looks down the filter chain to see whether there is a non-filter that can actually convert the compressed writes into compressed data (and thus normal writes).

2020-09-07block: Drop bdrv_is_encrypted()Max Reitz
The original purpose of bdrv_is_encrypted() was to inquire whether a BDS can be used without the user entering a password or not. It has not been used for that purpose for quite some time. Actually, it is not even fit for that purpose, because to answer that question, it would have recursively query all of the given node's children. So now we have to decide in which direction we want to fix bdrv_is_encrypted(): Recursively query all children, or drop it and just use bs->encrypted to get the current node's status? Nowadays, its only purpose is to report through bdrv_query_image_info() whether the given image is encrypted or not. For this purpose, it is probably more interesting to see whether a given node itself is encrypted or not (otherwise, a management application cannot discern for certain which nodes are really encrypted and which just have encrypted children).

2020-09-07block: Add child access functionsMax Reitz
There are BDS children that the general block layer code can access, namely bs->file and bs->backing. Since the introduction of filters and external data files, their meaning is not quite clear. bs->backing can be a COW source, or it can be a filtered child; bs->file can be a filtered child, it can be data and metadata storage, or it can be just metadata storage. This overloading really is not helpful. This patch adds functions that retrieve the correct child for each exact purpose. Later patches in this series will make use of them. Doing so will allow us to handle filter nodes in a meaningful way. Signed-off-by: Max Reitz <mreitz@redhat.com> Reviewed-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>
