hw/hyperv/hyperv.c: Use device_cold_reset() instead of device_legacy_reset()

2022-10-27T09:27:23+00:00

The semantic difference between the deprecated device_legacy_reset() function and the newer device_cold_reset() function is that the new function resets both the device itself and any qbuses it owns, whereas the legacy function resets just the device itself and nothing else. In hyperv_synic_reset() we reset a SynICState, which has no qbuses, so for this purpose the two functions behave identically and we can stop using the deprecated one.

hw/hyperv/vmbus: Remove unused vmbus_load/save_req()

2022-05-30T17:49:42+00:00

vmbus_save_req() and vmbus_load_req() are not used. Remove them to avoid maintaining dead code. This essentially reverts commit 4dd8a7064b8a6527f99a62be11 ("vmbus: add infrastructure to save/load vmbus requests").

util: rename qemu_*block() socket functions

2022-05-03T11:53:20+00:00

The qemu_*block() functions are meant to be be used with sockets (the win32 implementation expects SOCKET) Over time, those functions where used with Win32 SOCKET or file-descriptors interchangeably. But for portability, they must only be used with socket-like file-descriptors. FDs can use g_unix_set_fd_nonblocking() instead. Rename the functions with "socket" in the name to prevent bad usages. This is effectively reverting commit f9e8cacc5557e43 ("oslib-posix: rename socket_set_nonblock() to qemu_set_nonblock()"). Signed-off-by: Marc-André Lureau Reviewed-by: Stefan Hajnoczi

hyperv: Add support to process syndbg commands

2022-04-06T12:31:56+00:00

SynDbg commands can come from two different flows: 1. Hypercalls, in this mode the data being sent is fully encapsulated network packets. 2. SynDbg specific MSRs, in this mode only the data that needs to be transfered is passed.

hyperv: SControl is optional to enable SynIc

2022-04-06T12:31:56+00:00

SynIc can be enabled regardless of the SControl mechanisim which can register a GSI for a given SintRoute. This behaviour can achived by setting enabling SIMP and then the guest will poll on the message slot. Once there is another message pending the host will set the message slot with the pending flag. When the guest polls from the message slot, in case the pending flag is set it will write to the HV_X64_MSR_EOM indicating it has cleared the slot and we can try and push our message again.

vmbus: Don't make QOM property registration conditional

2021-07-06T22:04:38+00:00

Having properties registered conditionally makes QOM type introspection difficult. Instead of skipping registration of the "instanceid" property, always register the property but validate its value against the instance id required by the class.
