2019-12-18block: Error out on image creation with conflicting size optionsKevin Wolf
If both the create options (qemu-img create -o ...) and the size parameter were given, the size parameter was silently ignored. Instead, make specifying two sizes an error. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
2019-12-18qemu-img: fix info --backing-chain --image-optsStefan Hajnoczi
Only apply --image-opts to the topmost image when listing an entire backing chain. It is incorrect to treat backing filenames as image options. Assuming we have the backing chain t.IMGFMT.base <- t.IMGFMT.mid <- t.IMGFMT, qemu-img info fails as follows: $ qemu-img info --backing-chain --image-opts \ driver=qcow2,file.driver=file,file.filename=t.IMGFMT qemu-img: Could not open 'TEST_DIR/t.IMGFMT.mid': Cannot find device=TEST_DIR/t.IMGFMT.mid nor node_name=TEST_DIR/t.IMGFMT.mid Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Alberto Garcia <berto@igalia.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2019-12-18iotests: Skip test 079 if it is not possible to create large filesThomas Huth
Test 079 fails in the arm64, s390x and ppc64le LXD containers on Travis (which we will hopefully enable in our CI soon). These containers apparently do not allow large files to be created. Test 079 tries to create a 4G sparse file, which is apparently already too big for these containers, so check first whether we can really create such files before executing the test.

Test 060 fails in the arm64, s390x and ppc64le LXD containers on Travis (which we will hopefully enable in our CI soon). These containers apparently do not allow large files to be created.

2019-12-18iotests: Provide a function for checking the creation of huge filesThomas Huth
Some tests create huge (but sparse) files, and to be able to run those tests in certain limited environments (like CI containers), we have to check for the possibility to create such files first. Thus let's introduce a common function to check for large files, and replace the already existing checks in the iotests 005 and 220 with this function.

2019-12-17pseries: disable migration-test if /dev/kvm cannot be usedLaurent Vivier
On ppc64, migration-test only works with kvm_hv, and we already have a check to verify the module is loaded. kvm_hv module can be loaded in memory and /sys/module/kvm_hv exists, but on some systems (like build systems) /dev/kvm can be missing (by administrators choice). And as kvm_hv exists test-migration is started but QEMU falls back to TCG because it cannot be used: Could not access KVM kernel module: No such file or directory failed to initialize KVM: No such file or directory Back to tcg accelerator And as the test is done with TCG, it fails. As for s390x, we must check for the existence and the access rights of /dev/kvm.

2019-12-17Remove the core bluetooth codeThomas Huth
It's been deprecated since QEMU v3.1. We've explicitly asked in the deprecation message that people should speak up on qemu-devel in case they are still actively using the bluetooth part of QEMU, but nobody ever replied that they are really still using it. I've tried it on my own to use this bluetooth subsystem for one of my guests, but I was also not able to get it running anymore: When I was trying to pass-through a real bluetooth device, either the guest did not see the device at all, or the guest crashed. Even worse for the emulated device: When running qemu-system-x86_64 -bt device:keyboard QEMU crashes once you hit a key. So it seems like the bluetooth stack is not only neglected, it is completely bitrotten, as far as I can tell. The only attention that this code got during the past years were some CVEs that have been spotted there. So this code is a burden for the developers, without any real benefit anymore. Time to remove it. Note: hw/bt/Kconfig only gets cleared but not removed here yet. Otherwise there is a problem with the *-softmmu/config-devices.mak.d dependency files - they still contain a reference to this file which gets evaluated first on some build hosts, before the file gets properly recreated. To avoid breaking these builders, we still need the file around for some time. It will get removed in a couple of weeks instead.

The XSCOM bus is implemented with a QOM interface, which is mostly generic from a CPU type standpoint, except for the computation of addresses on the Pervasive Connect Bus (PCB) network. This is handled by the pnv_xscom_pcba() function with a switch statement based on the chip_type class level attribute of the CPU chip. This can be achieved using QOM. Also the address argument is masked with PNV_XSCOM_SIZE - 1, which is for POWER8 only. Addresses may have different sizes with other CPU types.

2019-12-17ppc/pnv: Fix OCC common area region mappingCédric Le Goater
The OCC common area is mapped at a unique address on the system and each OCC is assigned a segment to expose its sensor data : ------------------------------------------------------------------------- | Start (Offset from | End | Size |Description | | BAR2 base address) | | | | ------------------------------------------------------------------------- | 0x00580000 | 0x005A57FF |150kB |OCC 0 Sensor Data Block| | 0x005A5800 | 0x005CAFFF |150kB |OCC 1 Sensor Data Block| | : | : | : | : | | 0x00686800 | 0x006ABFFF |150kB |OCC 7 Sensor Data Block| | 0x006AC000 | 0x006FFFFF |336kB |Reserved | ------------------------------------------------------------------------- Maximum size is 1.5MB. We could define a "OCC common area" memory region at the machine level and sub regions for each OCC. But it adds some extra complexity to the models. Fix the current layout with a simpler model.

2019-12-17ppc/pnv: Introduce PBA registersCédric Le Goater
The PBA bridge unit (Power Bus Access) connects the OCC (On Chip Controller) to the Power bus and System Memory. The PBA is used to gather sensor data, for power management, for sleep states, for initial boot, among other things. The PBA logic provides a set of four registers PowerBus Access Base Address Registers (PBABAR0..3) which map the OCC address space to the PowerBus space. These registers are setup by the initial FW and define the PowerBus Range of system memory that can be accessed by PBA. The current modeling of the PBABAR registers is done under the common XSCOM handlers. We introduce a specific XSCOM regions for these registers and fix : - BAR sizes and BAR masks - The mapping of the OCC common area. It is common to all chips and should be mapped once. We will address per-OCC area in the next change. - OCC common area is in BAR 3 on P8 Inspired by previous work of Balamuruhan S <bala24@linux.ibm.com> Signed-off-by: Cédric Le Goater <clg@kaod.org> Message-Id: <20191211082912.2625-2-clg@kaod.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

The Processor Utilisation of Resources Register (PURR) and Scaled Processor Utilisation of Resources Register (SPURR) provide an estimate of the resources used by the thread, present on POWER7 and later processors. Currently the [S]PURR registers simply count at the rate of the timebase. Preserve this behaviour but rework the implementation to store an offset like the timebase rather than doing the calculation manually. Also allow hypervisor write access to the register along with the currently available read access.

2019-12-17target/ppc: Implement the VTB for HV accessSuraj Jitindar Singh
The virtual timebase register (VTB) is a 64-bit register which increments at the same rate as the timebase register, present on POWER8 and later processors. The register is able to be read/written by the hypervisor and read by the supervisor. All other accesses are illegal. Currently the VTB is just an alias for the timebase (TB) register. Implement the VTB so that is can be read/written independent of the TB. Make use of the existing method for accessing timebase facilities where by the compensation is stored and used to compute the value on reads/is updated on writes.
