hyperv: Avoid -Wflex-array-member-not-at-end warning2025-12-18T19:42:01+00:00Gustavo A. R. Silvagustavoars@kernel.org2025-12-12T06:44:50+00:00urn:sha1:52f758edc9f9f0b1f4f83eb668a5f76482ce00ca
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
Use the new __TRAILING_OVERLAP() helper to fix the following warning:
include/hyperv/hvgdk_mini.h:581:25: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
This helper creates a union between a flexible-array member (FAM) and a
set of MEMBERS that would otherwise follow it.
This overlays the trailing MEMBER u64 gva_list[]; onto the FAM
struct hv_tlb_flush_ex::hv_vp_set.bank_contents[], while keeping
the FAM and the start of MEMBER aligned.
The static_assert() ensures this alignment remains, and it's
intentionally placed inmediately after the related structure --no
blank line in between.

Interrupt control structure (union hv_interupt_control) has different
fields when it comes to x86 vs ARM64. Bring in the correct structure
from HyperV header files and adjust the existing interrupt routing
code accordingly.

Provide an interface for Virtual Machine Monitor like OpenVMM and its
use as OpenHCL paravisor to control VTL0 (Virtual trust Level).
Expose devices and support IOCTLs for features like VTL creation,
VTL0 memory management, context switch, making hypercalls,
mapping VTL0 address space to VTL2 userspace, getting new VMBus
messages and channel events in VTL2 etc.

In preparation for the subsequent crashdump patches, copy two hypercall
numbers to the guest ABI header published by Hyper-V. One to notify
hypervisor of an event that occurs in the root partition, other to ask
hypervisor to disable the hypervisor.

mshv: Introduce new hypercall to map stats page for L1VH partitions2025-11-15T06:18:16+00:00Jinank Jainjinankjain@linux.microsoft.com2025-10-10T21:55:51+00:00urn:sha1:d62313bdf5961b5f815f0b212f029cf146a8a804
Introduce HVCALL_MAP_STATS_PAGE2 which provides a map location (GPFN)
to map the stats to. This hypercall is required for L1VH partitions,
depending on the hypervisor version. This uses the same check as the
state page map location; mshv_use_overlay_gpfn().
Add mshv_map_vp_state_page() helpers to use this new hypercall or the
old one depending on availability.
For unmapping, the original HVCALL_UNMAP_STATS_PAGE works for both
cases.

This hypercall can be used to fetch extended properties of a
partition. Extended properties are properties with values larger than
a u64. Some of these also need additional input arguments.
