2017-10-15pci: Add INTERFACE_CONVENTIONAL_PCI_DEVICE to Conventional PCI devicesEduardo Habkost
Add INTERFACE_CONVENTIONAL_PCI_DEVICE to all direct subtypes of TYPE_PCI_DEVICE, except: 1) The ones that already have INTERFACE_PCIE_DEVICE set: * base-xhci * e1000e * nvme * pvscsi * vfio-pci * virtio-pci * vmxnet3 2) base-pci-bridge Not all PCI bridges are Conventional PCI devices, so INTERFACE_CONVENTIONAL_PCI_DEVICE is added only to the subtypes that are actually Conventional PCI: * dec-21154-p2p-bridge * i82801b11-bridge * pbm-bridge * pci-bridge The direct subtypes of base-pci-bridge not touched by this patch are: * xilinx-pcie-root: Already marked as PCIe-only. * pcie-pci-bridge: Already marked as PCIe-only. * pcie-port: all non-abstract subtypes of pcie-port are already marked as PCIe-only devices. 3) megasas-base Not all megasas devices are Conventional PCI devices, so the interface names are added to the subclasses registered by megasas_register_types(), according to information in the megasas_devices[] array. "megasas-gen2" already implements INTERFACE_PCIE_DEVICE, so add INTERFACE_CONVENTIONAL_PCI_DEVICE only to "megasas".

2017-09-27macio: use object link between MACIO_IDE and MAC_DBDMA objectMark Cave-Ayland
Using a standard QOM object link we can pass a reference to the MAC_DBDMA controller to the MACIO_IDE object which removes the last external parameter to macio_ide_register_dma().

2017-09-27macio: pass channel into MACIOIDEState via qdev propertyMark Cave-Ayland
One of the reasons macio_ide_register_dma() needs to exist is because the channel id isn't passed into the MACIO_IDE object. Pass in the channel id using a qdev property to remove this requirement.

2017-09-27mac_dbdma: remove unused IO fields from DBDMAStateMark Cave-Ayland
These fields were used to manually handle IO requests that weren't aligned to a sector boundary before this feature was supported by the block API. Once the block API changed to support byte-aligned IO requests, the macio controller was switched over to use it in commit be1e343 but these fields were accidentally left behind.

2017-09-27ppc/mac: More rework of the DBDMA emulationBenjamin Herrenschmidt
This completely reworks the handling of the control register according to my understanding of the HW and the spec. It should (hopefully ... still testing) fix a number of issues most notably cases of MacOS hanging. Also update dbdma_unassigned_rw() and dbdma_unassigned_flush() to have the expected behaviour now that flush is handled slightly differently.

2017-07-20configure: Rename CONFIG_IVSHMEM to CONFIG_IVSHMEM_DEVICEPeter Maydell
The current CONFIG_IVSHMEM is confusing, because it looks like it's a flag for "do we have ivshmem support?", but actually it's a flag for "is the ivshmem PCI device being compiled?" (and implicitly "do we have ivshmem support?" is tested with CONFIG_EVENTFD). Rename it to CONFIG_IVSHMEM_DEVICE to clear this confusion up; shortly we will add a new CONFIG_IVSHMEM which really does indicate whether the host can support ivshmem.

In some cases a failing VMSTATE_*_EQUAL does not mean we detected a bug, but it's actually the best we can do. Especially in these cases a verbose error message is required. Let's introduce infrastructure for specifying a error hint to be used if equal check fails. Let's do this by adding a parameter to the _EQUAL macros called _err_hint.

Instead of having its own mmap handling code, reuse the code from exec.c.

2017-06-13hw/misc/exynos4210_pmu: Add support for system poweroffKrzysztof Kozlowski
On all Exynos-based boards, the system powers down itself by driving PS_HOLD signal low - eight bit in PS_HOLD_CONTROL register of PMU. Handle writing to respective PMU register to fix power off failure: reboot: Power down Unable to poweroff system shutdown: 31 output lines suppressed due to ratelimiting Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000000 CPU: 0 PID: 1 Comm: shutdown Not tainted 4.11.0-rc8 #846 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) [<c031050c>] (unwind_backtrace) from [<c030ba6c>] (show_stack+0x10/0x14) [<c030ba6c>] (show_stack) from [<c05b2800>] (dump_stack+0x88/0x9c) [<c05b2800>] (dump_stack) from [<c03d3140>] (panic+0xdc/0x268) [<c03d3140>] (panic) from [<c0343614>] (do_exit+0xa90/0xab4) [<c0343614>] (do_exit) from [<c035f2dc>] (SyS_reboot+0x164/0x1d0) [<c035f2dc>] (SyS_reboot) from [<c0307c80>] (ret_fast_syscall+0x0/0x3c) Additionally the initial value of PS_HOLD has to be changed because recent Linux kernel (v4.12-rc1) uses regmap cache for this access. When the register is kept at reset value, the kernel will not issue a write to it. Usually the bootloader sets the eight bit of PS_HOLD high so mimic its existence here.

2017-06-02char: move CharBackend handling in char-fe unitMarc-André Lureau
Move all the frontend struct and methods to a seperate unit. This avoids accidentally mixing backend and frontend calls, and helps with readabilty.

Export qemu_chr_write(), and use a macro for qemu_chr_write_all() (nb: yes, CharBackend is for char frontend :) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org>

2017-05-23shutdown: Add source information to SHUTDOWN and RESETEric Blake
Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.
