2019-07-01aspeed: Link SCU to the watchdogJoel Stanley
The ast2500 uses the watchdog to reset the SDRAM controller. This operation is usually performed by u-boot's memory training procedure, and it is enabled by setting a bit in the SCU and then causing the watchdog to expire. Therefore, we need the watchdog to be able to access the SCU's register space. This causes the watchdog to not perform a system reset when the bit is set. In the future it could perform a reset of the SDMC model.

The XDMA engine embedded in the Aspeed SOCs performs PCI DMA operations between the SOC (acting as a BMC) and a host processor in a server. The XDMA engine exists on the AST2400, AST2500, and AST2600 SOCs, so enable it for all of those. Add trace events on the important register writes in the XDMA engine.

2019-07-01aspeed: introduce a configurable number of CPU per machineCédric Le Goater
The current models of the Aspeed SoCs only have one CPU but future ones will support SMP. Introduce a new num_cpus field at the SoC class level to define the number of available CPUs per SoC and also introduce a 'num-cpus' property to activate the CPUs configured for the machine. The max_cpus limit of the machine should depend on the SoC definition but, unfortunately, these values are not available when the machine class is initialized. This is the reason why we add a check on num_cpus in the AspeedSoC realize handler. SMP support will be activated when models for such SoCs are implemented.

2019-07-01pcie: check that slt ctrl changed before deletingMichael S. Tsirkin
During boot, linux would sometimes overwrites control of a powered off slot before powering it on. Unfortunately QEMU interprets that as a power off request and ejects the device. For example: /x86_64-softmmu/qemu-system-x86_64 -enable-kvm -S -machine q35 \ -device pcie-root-port,id=pcie_root_port_0,slot=2,chassis=2,addr=0x2,bus=pcie.0 \ -monitor stdio disk.qcow2 (qemu)device_add virtio-balloon-pci,id=balloon,bus=pcie_root_port_0 (qemu)cont Balloon is deleted during guest boot. To fix, save control beforehand and check that power or led state actually change before ejecting. Note: this is more a hack than a solution, ideally we'd find a better way to detect ejects, or move away from ejects completely and instead monitor whether it's safe to delete device due to e.g. its power state.

2019-06-24xen: Import other xen/io/*.hAnthony PERARD
A Xen public header have been imported into QEMU (by f65eadb639 "xen: import ring.h from xen"), but there are other header that depends on ring.h which come from the system when building QEMU. This patch resolves the issue of having headers from the system importing a different copie of ring.h. This patch is prompt by the build issue described in the previous patch: 'Revert xen/io/ring.h of "Clean up a few header guard symbols"' ring.h and the new imported headers are moved to "include/hw/xen/interface" as those describe interfaces with a guest. The imported headers are cleaned up a bit while importing them: some part of the file that QEMU doesn't use are removed (description of how to make hypercall in grant_table.h have been removed). Other cleanup: - xen-mapcache.c and xen-legacy-backend.c don't need grant_table.h. - xenfb.c doesn't need event_channel.h.

2019-06-24xen-bus / xen-block: add support for event channel pollingPaul Durrant
This patch introduces a poll callback for event channel fd-s and uses this to invoke the channel callback function. To properly support polling, it is necessary for the event channel callback function to return a boolean saying whether it has done any useful work or not. Thus xen_block_dataplane_event() is modified to directly invoke xen_block_handle_requests() and the latter only returns true if it actually processes any requests. This also means that the call to qemu_bh_schedule() is moved into xen_block_complete_aio(), which is more intuitive since the only reason for doing a deferred poll of the shared ring should be because there were previously insufficient resources to fully complete a previous poll.

2019-06-24xen-bus: use a separate fd for each event channelPaul Durrant
To better support use of IOThread-s it will be necessary to be able to set the AioContext for each XenEventChannel and hence it is necessary to open a separate handle to libxenevtchan for each channel. This patch stops using NotifierList for event channel callbacks, replacing that construct by a list of complete XenEventChannel structures. Each of these now has a xenevtchn_handle pointer in place of the single pointer previously held in the XenDevice structure. The individual handles are opened/closed in xen_device_bind/unbind_event_channel(), replacing the single open/close in xen_device_realize/unrealize(). NOTE: This patch does not add an AioContext parameter to xen_device_bind_event_channel(). That will be done in a subsequent patch.

2019-06-21hw: Nuke hw_compat_4_0_1 and pc_compat_4_0_1Greg Kurz
Commit c87759ce876a fixed a regression affecting pc-q35 machines by introducing a new pc-q35-4.0.1 machine version to be used instead of pc-q35-4.0. The only purpose was to revert the default behaviour of not using split irqchip, but the change also introduced the usual hw_compat and pc_compat bits, and wired them for pc-q35 only. This raises questions when it comes to add new compat properties for 4.0* machine versions of any architecture. Where to add them ? In 4.0, 4.0.1 or both ? Error prone. Another possibility would be to teach all other architectures about 4.0.1. This solution isn't satisfying, especially since this is a pc-q35 specific issue. It turns out that the split irqchip default is handled in the machine option function and doesn't involve compat lists at all. Drop all the 4.0.1 compat lists and use the 4.0 ones instead in the 4.0.1 machine option function. Move the compat props that were added to the 4.0.1 since c87759ce876a to 4.0. Even if only hw_compat_4_0_1 had an impact on other architectures, drop pc_compat_4_0_1 as well for consistency.

2019-06-18block: Add bdrv_child_refresh_perms()Max Reitz
If a block node uses bdrv_child_try_set_perm() to change the permission it takes on its child, the result may be very short-lived. If anything makes the block layer recalculate the permissions internally, it will invoke the node driver's .bdrv_child_perm() implementation. The permission/shared permissions masks that returns will then override the values previously passed to bdrv_child_try_set_perm(). If drivers want a child edge to have specific values for the permissions/shared permissions mask, it must return them in .bdrv_child_perm(). Consequentially, there is no need for them to pass the same values to bdrv_child_try_set_perm() then: It is better to have a function that invokes .bdrv_child_perm() and calls bdrv_child_try_set_perm() with the result.

2019-06-17monitor: Fix return type of monitor_fdset_dup_fd_findYury Kotov
monitor_fdset_dup_fd_find_remove() and monitor_fdset_dup_fd_find() return mon_fdset->id which is int64_t. Downcasting from int64_t to int leads to a bug with removing fd from fdset with id >= 2^32. So, fix return types for these function.

2019-06-17hw/arm: Correctly disable FPU/DSP for some ARMSSE-based boardsPeter Maydell
The SSE-200 hardware has configurable integration settings which determine whether its two CPUs have the FPU and DSP: * CPU0_FPU (default 0) * CPU0_DSP (default 0) * CPU1_FPU (default 1) * CPU1_DSP (default 1) Similarly, the IoTKit has settings for its single CPU: * CPU0_FPU (default 1) * CPU0_DSP (default 1) Of our four boards that use either the IoTKit or the SSE-200: * mps2-an505, mps2-an521 and musca-a use the default settings * musca-b1 enables FPU and DSP on both CPUs Currently QEMU models all these boards using CPUs with both FPU and DSP enabled. This means that we are incorrect for mps2-an521 and musca-a, which should not have FPU or DSP on CPU0. Create QOM properties on the ARMSSE devices corresponding to the default h/w integration settings, and make the Musca-B1 board enable FPU and DSP on both CPUs. This fixes the mps2-an521 and musca-a behaviour, and leaves the musca-b1 and mps2-an505 behaviour unchanged.

Add new properties to allow setting the maximum display resolution. Resolutions larger than that will not be included in the mode list. In linux guests xrandr can be used to list modes. Note: The existing xres and yres properties set the preferred display resolution, i.e. the mode should be first in the mode list and guests should use it by default.

Commit 58ea30f5145 "Clean up header guards that don't match their file name" messed up contrib/elf2dmp/qemu_elf.h and tests/migration/migration-test.h. It missed target/cris/opcode-cris.h and tests/uefi-test-tools/UefiTestToolsPkg/Include/Guid/BiosTablesTest.h due to the scripts/clean-header-guards.pl bug fixed in the previous commit. Commit a8b991b52dc "Clean up ill-advised or unusual header guards" missed include/hw/xen/io/ring.h for the same reason. Commit 3979fca4b69 "disas: Rename include/disas/bfd.h back to include/disas/dis-asm.h" neglected to update the guard symbol for the rename. Commit a331c6d7741 "semihosting: implement a semihosting console" created include/hw/semihosting/console.h with an ill-advised guard symbol. Clean them up.

2019-06-12Normalize position of header guardMarkus Armbruster
This is the common header guard idiom: /* * File comment */ #ifndef GUARD_SYMBOL_H #define GUARD_SYMBOL_H ... actual contents ... #endif A few of our headers have some #include before the guard. target/tilegx/spr_def_64.h has #ifndef __DOXYGEN__ outside the guard. A few more have the #define elsewhere. Change them to match the common idiom. For spr_def_64.h, that means dropping #ifndef __DOXYGEN__.
