2023-08-28configure: fix and complete detection of tricore toolsPaolo Bonzini1-4/+1
The tricore tools are not detected when they are installed in the host system, only if they are taken from an external container. For this reason the build-tricore-softmmu job was not running the TCG tests. In addition the container provides all tools, not just as/ld/gcc, so there is no need to special case tricore.

2023-08-24hw/loongarch: Fix ACPI processor id off-by-one errorJiajie Chen1-1/+1
In hw/acpi/aml-build.c:build_pptt() function, the code assumes that the ACPI processor id equals to the cpu index, for example if we have 8 cpus, then the ACPI processor id should be in range 0-7. However, in hw/loongarch/acpi-build.c:build_madt() function we broke the assumption. If we have 8 cpus again, the ACPI processor id in MADT table would be in range 1-8. It violates the following description taken from ACPI spec 6.4 table 5.138: If the processor structure represents an actual processor, this field must match the value of ACPI processor ID field in the processor’s entry in the MADT. It will break the latest Linux 6.5-rc6 with the following error message: ACPI PPTT: PPTT table found, but unable to locate core 7 (8) Invalid BIOS PPTT Here 7 is the last cpu index, 8 is the ACPI processor id learned from MADT. With this patch, Linux can properly detect SMT threads when "-smp 8,sockets=1,cores=4,threads=2" is passed: Thread(s) per core: 2 Core(s) per socket: 2 Socket(s): 2 The detection of number of sockets is still wrong, but that is out of scope of the commit.

2023-08-24target/loongarch: Split fcc register to fcc0-7 in gdbstubJiajie Chen2-10/+15
Since GDB 13.1(GDB commit ea3352172), GDB LoongArch changed to use fcc0-7 instead of fcc register. This commit partially reverts commit 2f149c759 (`target/loongarch: Update gdb_set_fpu() and gdb_get_fpu()`) to match the behavior of GDB. Note that it is a breaking change for GDB 13.0 or earlier, but it is also required for GDB 13.1 or later to work.

2023-08-24hw/intc/loongarch_pch: fix edge triggered irq handlingBibo Mao1-1/+6
For edge triggered irq, qemu_irq_pulse is used to inject irq. It will set irq with high level and low level soon to simluate pulse irq. For edge triggered irq, irq is injected and set as pending at rising level, do not clear irq at lowering level. LoongArch pch interrupt will clear irq for lowering level irq, there will be problem. ACPI ged deivce is edge-triggered irq, it is used for cpu/memory hotplug. This patch fixes memory hotplug issue on LoongArch virt machine.

Using "-device virtio-gpu,blob=true" currently does not work on big endian hosts (like s390x). The guest kernel prints an error message like: [drm:virtio_gpu_dequeue_ctrl_func [virtio_gpu]] *ERROR* response 0x1200 (command 0x10c) and the display stays black. When running QEMU with "-d guest_errors", it shows an error message like this: virtio_gpu_create_mapping_iov: nr_entries is too big (83886080 > 16384) which indicates that this value has not been properly byte-swapped. And indeed, the virtio_gpu_create_blob_bswap() function (that should swap the fields in the related structure) fails to swap some of the entries. After correctly swapping all missing values here, too, the virtio-gpu device is now also working with blob=true on s390x hosts.

2023-08-23hw/s390x/s390-virtio-ccw: Remove superfluous code to set the NIC modelThomas Huth1-4/+0
The check for nd->model being NULL was originally required, but in commit e11f463295d95aba ("s390x/virtio: use qemu_check_nic_model()") the corresponding code had been replaced by a call to the function qemu_check_nic_model() - and this in turn calls qemu_find_nic_model() which contains the same check for nd->model being NULL again. So we can remove this from the calling site now.

2023-08-23target/s390x: Use a 16-bit immediate in VREPIlya Leoshkevich1-2/+2
Unlike most other instructions that contain an immediate element index, VREP's one is 16-bit, and not 4-bit. The code uses only 8 bits, so using, e.g., 0x101 does not lead to a specification exception. Fix by checking all 16 bits.

When FEAT_RME is implemented, these bits override the value of CNT[VP]_CTL_EL0.IMASK in Realm and Root state. Move the IRQ state update into a new gt_update_irq() function and test those bits every time we recompute the IRQ state. Since we're removing the IRQ state from some trace events, add a new trace event for gt_update_irq().

2023-08-22target/arm: Pass security space rather than flag for AT instructionsJean-Philippe Brucker3-30/+27
At the moment we only handle Secure and Nonsecure security spaces for the AT instructions. Add support for Realm and Root. For AArch64, arm_security_space() gives the desired space. ARM DDI0487J says (R_NYXTL): If EL3 is implemented, then when an address translation instruction that applies to an Exception level lower than EL3 is executed, the Effective value of SCR_EL3.{NSE, NS} determines the target Security state that the instruction applies to. For AArch32, some instructions can access NonSecure space from Secure, so we still need to pass the state explicitly to do_ats_write().
