2025-11-13firmware: stratix10-svc: Add support for async communicationMahesh Rao
Introduce support for asynchronous communication with the Stratix10 service channel. Define new structures to enable asynchronous messaging with the Secure Device Manager (SDM). Add and remove asynchronous support for existing channels. Implement initialization and cleanup routines for the asynchronous framework. Enable sending and polling of messages to the SDM asynchronously. The new public functions added are: - stratix10_svc_add_async_client: Adds a client to the service channel. - stratix10_svc_remove_async_client: Removes an asynchronous client from the service channel. - stratix10_svc_async_send: Sends an asynchronous message to the SDM mailbox in EL3 secure firmware. - stratix10_svc_async_poll: Polls the status of an asynchronous service request in EL3 secure firmware. - stratix10_svc_async_done: Marks an asynchronous transaction as complete and frees up the resources. These changes enhance the functionality of the Stratix10 service channel by allowing for more efficient and flexible communication with the firmware.

2025-11-11efi/runtime-wrappers: Keep track of the efi_runtime_lock ownerArd Biesheuvel
The EFI runtime wrappers use a file local semaphore to serialize access to the EFI runtime services. This means that any calls to the arch wrappers around the runtime services will also be serialized, removing the need for redundant locking. For robustness, add a facility that allows those arch wrappers to assert that the semaphore was taken by the current task.

2025-11-05efi/libstub: Fix page table access in 5-level to 4-level paging transitionUsama Arif
When transitioning from 5-level to 4-level paging, the existing code incorrectly accesses page table entries by directly dereferencing CR3 and applying PAGE_MASK. This approach has several issues: - __native_read_cr3() returns the raw CR3 register value, which on x86_64 includes not just the physical address but also flags Bits above the physical address width of the system (i.e. above __PHYSICAL_MASK_SHIFT) are also not masked. - The pgd value is masked by PAGE_SIZE which doesn't take into account the higher bits such as _PAGE_BIT_NOPTISHADOW. Replace this with proper accessor functions: - native_read_cr3_pa(): Uses CR3_ADDR_MASK to additionally mask metadata out of CR3 (like SME or LAM bits). All remaining bits are real address bits or reserved and must be 0. - mask pgd value with PTE_PFN_MASK instead of PAGE_MASK, accounting for flags above bit 51 (_PAGE_BIT_NOPTISHADOW in particular). Bits below 51, but above the max physical address are reserved and must be 0.

2025-10-30kbuild: Add '-fms-extensions' to areas with dedicated CFLAGSNathan Chancellor
This is a follow up to commit c4781dc3d1cf ("Kbuild: enable -fms-extensions") but in a separate change due to being substantially different from the initial submission. There are many places within the kernel that use their own CFLAGS instead of the main KBUILD_CFLAGS, meaning code written with the main kernel's use of '-fms-extensions' in mind that may be tangentially included in these areas will result in "error: declaration does not declare anything" messages from the compiler. Add '-fms-extensions' to all these areas to ensure consistency, along with -Wno-microsoft-anon-tag to silence clang's warning about use of the extension that the kernel cares about using. parisc does not build with clang so it does not need this warning flag. LoongArch does not need it either because -W flags from KBUILD_FLAGS are pulled into cflags-vdso.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 SEV and apic updates from Borislav Petkov: - Add functionality to provide runtime firmware updates for the non-x86 parts of an AMD platform like the security processor (ASP) firmware, modules etc, for example. The intent being that these updates are interim, live fixups before a proper BIOS update can be attempted - Add guest support for AMD's Secure AVIC feature which gives encrypted guests the needed protection against a malicious hypervisor generating unexpected interrupts and injecting them into such guest, thus interfering with its operation in an unexpected and negative manner. The advantage of this scheme is that the guest determines which interrupts and when to accept them vs leaving that to the benevolence (or not) of the hypervisor - Strictly separate the startup code from the rest of the kernel where former is executed from the initial 1:1 mapping of memory. The problem was that the toolchain-generated version of the code was being executed from a different mapping of memory than what was "assumed" during code generation, needing an ever-growing pile of fixups for absolute memory references which are invalid in the early, 1:1 memory mapping during boot. The major advantage of this is that there's no need to check the 1:1 mapping portion of the code for absolute relocations anymore and get rid of the RIP_REL_REF() macro sprinkling all over the place.

2025-09-29efi/x86: Memory protection on EfiGcdMemoryTypeMoreReliableLenny Szubowicz
Check for needed memory protection changes on EFI DXE GCD memory space descriptors with type EfiGcdMemoryTypeMoreReliable in addition to EfiGcdMemoryTypeSystemMemory. This fixes a fault on entry into the decompressed kernel from the EFI stub that occurs when the memory allocated for the decompressed kernel is more reliable memory, has NX/XP set, and the kernel needs to use the EFI DXE protocol to adjust memory protections. The memory descriptors returned by the DXE protocol GetMemorySpaceDescriptor() service use a different GCD memory type to distinguish more reliable memory ranges from their conventional counterparts. This is in contrast to the EFI memory descriptors returned by the EFI GetMemoryMap() service which use the EFI_MEMORY_MORE_RELIABLE memory attributes flag to identify EFI_CONVENTIONAL_MEMORY type regions that have this additional property.

Device Tree bindings - allow multiple SCMI instances by suffixing node names (Nikunj Kela). 2. Code hardening - constify both scmi_{transport,voltage_proto}_ops so they reside in read-only memory (Christophe JAILLET). 3. VirtIO transport initialization - set DRIVER_OK before SCMI probing to prevent potential stalls; while recent rework removes the practical risk, this ensures correctness (Junnan Wu). 4. Quirk handling - fix a critical bug by preventing writes to string constants, avoiding faults in read-only memory (Johan Hovold). 5. i.MX SCMI MISC protocol - extend support to discover board info, retrieve configuration and build data, and document the new MISC_BOARD_INFO command; all handled gracefully if unsupported (Peng Fan). 6. Logging cleanup - simplify device tree node name logging by using the %pOF format to print full paths (Krzysztof Kozlowski). * tag 'scmi-updates-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: Simplify printks with pOF format firmware: arm_scmi: imx: Discover MISC board info from the system manager firmware: arm_scmi: imx: Support retrieving MISC protocol configuration info firmware: arm_scmi: imx: Discover MISC build info from the system manager firmware: arm_scmi: imx: Add documentation for MISC_BOARD_INFO firmware: arm_scmi: quirk: Prevent writes to string constants firmware: arm_scmi: Fix function name typo in scmi_perf_proto_ops struct firmware: arm_scmi: Mark VirtIO ready before registering scmi_virtio_driver firmware: arm_scmi: Constify struct scmi_transport_ops firmware: arm_scmi: Constify struct scmi_voltage_proto_ops dt-bindings: firmware: arm,scmi: Allow multiple instances Link: https://lore.kernel.org/r/20250915101341.2987516-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>
