* include/hw/ide: Unexport pci_piix3_xen_ide_unplug()Bernhard Beschow2022-06-091-1/+47
| | | | | | | | | | | | | | | | | | This function was declared in a generic and public header, implemented in a device-specific source file but only used in xen_platform. Given its 'aux' parameter, this function is more xen-specific than piix-specific. Also, the hardcoded magic constants seem to be generic and related to PCIIDEState and IDEBus rather than piix. Therefore, move this function to xen_platform, unexport it, and drop the "piix3" in the function name as well.

* xen-platform: separate unplugging of NVMe disksStefano Stabellini2017-07-181-12/+35
| | | | | | | | | | | | | | | | | | | | | Commit 090fa1c8 "add support for unplugging NVMe disks..." extended the existing disk unplug flag to cover NVMe disks as well as IDE and SCSI. The recent thread on the xen-devel mailing list [1] has highlighted that this is not desirable behaviour: PV frontends should be able to distinguish NVMe disks from other types of disk and should have separate control over whether they are unplugged. This patch defines a new bit in the unplug mask for this purpose (see Xen commit [2]) and also tidies up the definitions of, and improves the comments regarding, the previously exiting bits in the protocol.

| | | | | | | | | | | | | | | | | | | | | | | The Xen HVM unplug protocol [1] specifies a mechanism to allow guests to request unplug of 'aux' disks (which is stated to mean all IDE disks, except the primary master). This patch adds support for that unplug request. NOTE: The semantics of what happens if unplug of all disks and 'aux' disks is simultaneously requests is not clear. The patch makes that assumption that an 'all' request overrides an 'aux' request.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little.
