2018-03-06use g_path_get_basename instead of basenameJulia Suvorova3-3/+3
basename(3) and dirname(3) modify their argument and may return pointers to statically allocated memory which may be overwritten by subsequent calls. g_path_get_basename and g_path_get_dirname have no such issues, and therefore more preferable.

2018-03-06openpic_kvm: drop address_space_to_flatview callPaolo Bonzini1-4/+0
The MemoryListener is registered on address_space_memory, there is not much to assert. This currently works because the callback is invoked only once when the listener is registered, but section->fv is the _new_ FlatView, not the old one on later calls and that would break. This confines address_space_to_flatview to exec.c and memory.c.

2018-03-06scsi: Remove automatic creation of SCSI controllers with -drive if=scsiThomas Huth6-75/+3
Automatic creation of SCSI controllers for "-drive if=scsi" for x86 machines was quite a bad idea (see description of commit f778a82f0c179 for details). This is marked as deprecated since QEMU v2.9.0, and as far as I know, nobody complained that this is still urgently required anymore. Time to remove this now.

2018-03-06PPC: e500: Fix duplicate kernel load and device tree overlapDavid Engraf1-46/+70
This patch fixes an incorrect behavior when the -kernel argument has been specified without -bios. In this case the kernel was loaded twice. At address 32M as a raw image and afterwards by load_elf/load_uimage at the corresponding load address. In this case the region for the device tree and the raw kernel image may overlap. The patch fixes the behavior by loading the kernel image once with load_elf/load_uimage and skips loading the raw image. When here do not use bios_name/size for the kernel and use a more generic name called payload_name/size. New in v3: dtb must be stored between kernel and initrd because Linux can handle the dtb only within the first 64MB. Add a comment to clarify the behavior.

2018-03-06spapr: harden code that depends on VSMTGreg Kurz1-69/+75
VSMT must be set in order to compute VCPU ids. This means that the following functions must not be called before spapr_set_vsmt_mode() was called: - spapr_vcpu_id() - spapr_is_thread0_in_vcore() - xics_max_server_number() We had a recent regression where the latter would be called before VSMT was set, and broke migration of some old machine types. This patch adds assert() in the above functions to avoid problems in the future. Also, since VSMT is really a CPU related thing, spapr_set_vsmt_mode() is now called from spapr_init_cpus(), just before the first VSMT user.

2018-03-06spapr: register dummy ICPs laterGreg Kurz1-12/+12
Some older machine types create more ICPs than needed. We hence need to register up to xics_max_server_number() dummy ICPs to accomodate the migration of these machine types. Recent VSMT rework changed xics_max_server_number() to return DIV_ROUND_UP(max_cpus * spapr->vsmt, smp_threads) instead of DIV_ROUND_UP(max_cpus * kvmppc_smt_threads(), smp_threads); The change is okay but it requires spapr->vsmt to be set, which isn't the case with the current code. This causes the formula to return zero and we don't create dummy ICPs. This breaks migration of older guests as reported here: https://bugzilla.redhat.com/show_bug.cgi?id=1549087 The dummy ICP workaround doesn't really have a dependency on XICS itself. But it does depend on proper VCPU id numbering and it must be applied before creating vCPUs (ie, creating real ICPs). So this patch moves the workaround to spapr_init_cpus(), which already assumes VSMT to be set.

2018-03-06spapr: fix missing CPU core nodes in DT when running with TCGGreg Kurz1-7/+1
Commit 5d0fb1508e2d "spapr: consolidate the VCPU id numbering logic in a single place" introduced a helper to detect thread0 of a virtual core based on its VCPU id. This is used to create CPU core nodes in the DT, but it is broken in TCG. $ qemu-system-ppc64 -nographic -accel tcg -machine dumpdtb=dtb.bin \ -smp cores=16,maxcpus=16,threads=1 $ dtc -f -O dts dtb.bin | grep POWER8 PowerPC,POWER8@0 { PowerPC,POWER8@8 { instead of the expected 16 cores that we get with KVM: $ dtc -f -O dts dtb.bin | grep POWER8 PowerPC,POWER8@0 { PowerPC,POWER8@8 { PowerPC,POWER8@10 { PowerPC,POWER8@18 { PowerPC,POWER8@20 { PowerPC,POWER8@28 { PowerPC,POWER8@30 { PowerPC,POWER8@38 { PowerPC,POWER8@40 { PowerPC,POWER8@48 { PowerPC,POWER8@50 { PowerPC,POWER8@58 { PowerPC,POWER8@60 { PowerPC,POWER8@68 { PowerPC,POWER8@70 { PowerPC,POWER8@78 { This happens because spapr_get_vcpu_id() maps VCPU ids to cs->cpu_index in TCG mode. This confuses the code in spapr_is_thread0_in_vcore(), since it assumes thread0 VCPU ids to have a spapr->vsmt spacing. spapr_get_vcpu_id(cpu) % spapr->vsmt == 0 Actually, there's no real reason to expose cs->cpu_index instead of the VCPU id, since we also generate it with TCG. Also we already set it explicitly in spapr_set_vcpu_id(), so there's no real reason either to call kvm_arch_vcpu_id() with KVM. This patch unifies spapr_get_vcpu_id() to always return the computed VCPU id both in TCG and KVM. This is one step forward towards KVM<->TCG migration.

This reverts commit 4da97120d51a4383aa96d741a2b837f8c4bbcd0b. blk_aio_flush() now handles the blk->root == NULL case, so we no longer need this workaround.

2018-03-02mps2-an505: New board model: MPS2 with AN505 Cortex-M33 FPGA imagePeter Maydell2-0/+504
Define a new board model for the MPS2 with an AN505 FPGA image containing a Cortex-M33. Since the FPGA images for TrustZone cores (AN505, and the similar AN519 for Cortex-M23) have a significantly different layout of devices to the non-TrustZone images, we use a new source file rather than shoehorning them into the existing mps2.c.

The Arm IoT Kit includes a "security controller" which is largely a collection of registers for controlling the PPCs and other bits of glue in the system. This commit provides the initial skeleton of the device, implementing just the ID registers, and a couple of read-only read-as-zero registers.

2018-03-02hw/core/split-irq: Device that splits IRQ linesPeter Maydell2-0/+90
In some board or SoC models it is necessary to split a qemu_irq line so that one input can feed multiple outputs. We currently have qemu_irq_split() for this, but that has several deficiencies: * it can only handle splitting a line into two * it unavoidably leaks memory, so it can't be used in a device that can be deleted Implement a qdev device that encapsulates splitting of IRQs, with a configurable number of outputs. (This is in some ways the inverse of the TYPE_OR_IRQ device.)

2018-03-02qdev: Add new qdev_init_gpio_in_named_with_opaque()Peter Maydell1-3/+5
The function qdev_init_gpio_in_named() passes the DeviceState pointer as the opaque data pointor for the irq handler function. Usually this is what you want, but in some cases it would be helpful to use some other data pointer. Add a new function qdev_init_gpio_in_named_with_opaque() which allows the caller to specify the data pointer they want.
