2017-01-18fw-cfg: support writeable blobsMichael S. Tsirkin
Useful to send guest data back to QEMU. Changes from Laszlo Ersek <lersek@redhat.com>: - rebase the patch from Michael Tsirkin's original postings at [1] and [2] to the following patches: - loader: Allow a custom AddressSpace when loading ROMs - loader: Add AddressSpace loading support to uImages - loader: fix handling of custom address spaces when adding ROM blobs - reject such writes immediately that would exceed the end of the array, rather than performing a partial write before setting the error bit: see the (len != dma.length) condition - document the write interface [1] http://lists.nongnu.org/archive/html/qemu-devel/2016-02/msg04968.html [2] http://lists.nongnu.org/archive/html/qemu-devel/2016-03/msg02735.html Cc: "Gabriel L.

2017-01-10memhp: don't generate memory hotplug AML if it's not enabled/supportedIgor Mammedov
That reduces DSDT by 910 bytes when memory hotplug isn't enabled. While doing so drop intermediate variables/arguments passing around ACPI_MEMORY_HOTPLUG_IO_LEN and making it local to memory_hotplug.c, hardcoding it there as it can't change. Also don't pass around ACPI_MEMORY_HOTPLUG_BASE through intermediate variables/arguments where it's not needed. Instead initialize in module static variable when MMIO region is mapped and use that within memory_hotplug.c whenever it's required. That way MMIO base specified only at one place and AML with MMIO would always use the same value. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.

Check for KVM_CAP_ADJUST_CLOCK capability KVM_CLOCK_TSC_STABLE, which indicates that KVM_GET_CLOCK returns a value as seen by the guest at that moment.

2016-12-20Move target-* CPU file into a target/ folderThomas Huth
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

2016-12-16i386: amd_iommu: fix MMIO register count and accessPrasad J Pandit
IOMMU MMIO registers are divided in two groups by their offsets. Low offsets(<0x2000) registers are grouped into 'amdvi_mmio_low' table and higher offsets(>=0x2000) registers are grouped into 'amdvi_mmio_high' table. No of registers in each table is given by macro 'AMDVI_MMIO_REGS_LOW' and 'AMDVI_MMIO_REGS_HIGH' resp. Values of these two macros were swapped, resulting in an OOB access when reading 'amdvi_mmio_high' table. Correct these two macros. Also read from 'amdvi_mmio_low' table for lower address.

2016-11-30loader: fix handling of custom address spaces when adding ROM blobsLaszlo Ersek
* Commit 3e76099aacb4 ("loader: Allow a custom AddressSpace when loading ROMs") introduced the "Rom.as" field: (1) It modified the utility callers of rom_insert() to take "as" as a new parameter from *their* callers, and set "rom->as" from that parameter. The functions covered were rom_add_file() and rom_add_elf_program(). (2) It also modified rom_insert() itself, to auto-assign "&address_space_memory", in case the external caller passed -- and the utility caller forwarded -- as=NULL. Except, commit 3e76099aacb4 forgot to update the third utility caller of rom_insert(), under point (1), namely rom_add_blob(). * Later, commit 5e774eb3bd264 ("loader: Add AddressSpace loading support to uImages") added the load_uimage_as() function, and the rom_add_blob_fixed_as() function-like macro, with the necessary changes elsewhere to propagate the new "as" parameter to rom_add_blob(): load_uimage_as() load_uboot_image() rom_add_blob_fixed_as() rom_add_blob() At this point, the signature (and workings) of rom_add_blob() had been broken already, and the rom_add_blob_fixed_as() macro passed its "_as" parameter to rom_add_blob() as "callback_opaque". Given that the "fw_callback" parameter itself was set to NULL (correctly), this did no additional damage (the opaque arg would never be used), but ultimately it broke the new functionality of load_uimage_as(). * The load_uimage_as() function would be put to use in one of the later patches, commit e481a1f63c93 ("generic-loader: Add a generic loader"). * We can fix this only in a unified patch now. Append "AddressSpace *as" to the signature of rom_add_blob(), and handle the new parameter. Pass NULL from all current callers, except from rom_add_blob_fixed_as(), where "_as" has to be bumped to the proper position. * Note that rom_add_file() rejects the case when both "mr" and "as" are passed in as non-NULL. The action that this is apparently supposed to prevent is the rom->mr = mr; assignment (that's the only place where the "mr" parameter is used in rom_add_file()). In rom_add_blob() though, we have no "mr" parameter, and the actions done on the fw_cfg branch: if (fw_file_name && fw_cfg) { if (mc->rom_file_has_mr) { data = rom_set_mr(rom, OBJECT(fw_cfg), devpath); mr = rom->mr; } else { data = rom->data; } reflect those that are performed by rom_add_file() too (with mr==NULL): if (rom->fw_file && fw_cfg) { if ((!option_rom || mc->option_rom_has_mr) && mc->rom_file_has_mr) { data = rom_set_mr(rom, OBJECT(fw_cfg), devpath); } else { data = rom->data; } Hence we need no additional restrictions in rom_add_blob(). * Stable is not affected as both problematic commits appeared first in v2.8.0-rc0.

2016-11-28pci-assign: sync MSI/MSI-X cap and table with PCIDevicePeter Xu
Since commit e1d4fb2d ("kvm-irqchip: x86: add msi route notify fn"), kvm_irqchip_add_msi_route() starts to use pci_get_msi_message() to fetch MSI info. This requires that we setup MSI related fields in PCIDevice. For most devices, that won't be a problem, as long as we are using general interfaces like msi_init()/msix_init(). However, for pci-assign devices, MSI/MSI-X is treated differently - PCI assign devices are maintaining its own MSI table and cap information in AssignedDevice struct. however that's not synced up with PCIDevice's fields. That will leads to pci_get_msi_message() failed to find correct MSI capability, even with an NULL msix_table. A quick fix is to sync up the two places: both the capability bits and table address for MSI/MSI-X.

2016-11-18acpi: Use apic_id_limit when calculating legacy ACPI table sizeEduardo Habkost
The code that calculates the legacy ACPI table size for migration compatibility uses max_cpus when calculating legacy_aml_len (the size of the DSDT and SSDT tables). However, the SSDT grows according to APIC ID limit, not max_cpus. The bug is not triggered very often because of the 4k alignment on the table size. But it can be triggered if you are unlucky enough to cross a 4k boundary. Change the legacy_aml_len calculation to use apic_id_limit, to calculate the right size.

2016-11-02PCMachineState: introduce acpi_build_enabled fieldWei Liu
Introduce this field to control whether ACPI build is enabled by a particular machine or accelerator. It defaults to true if the machine itself supports ACPI build. Xen accelerator will disable it because Xen is in charge of building ACPI tables for the guest.

2016-11-01nvdimm acpi: introduce fit bufferXiao Guangrong
The buffer is used to save the FIT info for all the presented nvdimm devices which is updated after the nvdimm device is plugged or unplugged. In the later patch, it will be used to construct NVDIMM ACPI _FIT method which reflects the presented nvdimm devices after nvdimm hotplug As FIT buffer can not completely mapped into guest address space, OSPM will exit to QEMU multiple times, however, there is the race condition - FIT may be changed during these multiple exits, so that some rules are introduced: 1) the user should hold the @lock to access the buffer and 2) mark @dirty whenever the buffer is updated. @dirty is cleared for the first time OSPM gets fit buffer, if dirty is detected in the later access, OSPM will restart the access As fit should be updated after nvdimm device is successfully realized so that a new hotplug callback, post_hotplug, is introduced Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> Reviewed-by: Michael S.

2016-10-31*_run_on_cpu: introduce run_on_cpu_data typePaolo Bonzini
This changes the *_run_on_cpu APIs (and helpers) to pass data in a run_on_cpu_data type instead of a plain void *. This is because we sometimes want to pass a target address (target_ulong) and this fails on 32 bit hosts emulating 64 bit guests.

2016-10-31tcg: protect translation related stuff with tb_lock.KONRAD Frederic
This protects all translation related work with tb_lock() too ensure thread safety. This effectively serialises all code generation. In addition to the code generation we also take the lock for TB invalidation. This has a knock on effect of meaning tb_lock() is held for modification of the SoftMMU TLB by non-self threads which will be used in later patches.

Currently firmware uses 1 byte at 0x5F offset in RTC CMOS to get number of CPUs present at boot. However 1 byte is not enough to handle more than 255 CPUs. So add a new fw_cfg file that would allow QEMU to tell it. For compat reasons add file only for machine types that support more than 255 CPUs.
