coco/tdx-host: Don't expose P-SEAMLDR information on CPUs with erratum
TDX-capable CPUs clobber the current VMCS on P-SEAMLDR calls. Clearing the current VMCS behind KVM's back breaks KVM. Future CPUs will fix this by preserving the current VMCS across P-SEAMLDR calls. A future specification update will describe the VMCS-clearing behavior as an erratum and to state that it does not occur when IA32_VMX_BASIC[60] is set. Add a CPU bug bit and refuse to expose P-SEAMLDR information on affected CPUs. Use a CPU bug bit to stay consistent with X86_BUG_TDX_PW_MCE. As a bonus, the bug bit is visible to userspace, which allows userspace to determine why these sysfs files are not exposed, and it can also be checked by other kernel components in the future if needed. == Alternatives == Two workarounds were considered but both were rejected: 1. Save/restore the current VMCS around P-SEAMLDR calls. This produces ugly assembly code [1] and doesn't play well with #MCE or #NMI if they need to use the current VMCS. 2. Move KVM's VMCS tracking logic to the TDX core code, which would break the boundary between KVM and the TDX core code [2]. [ dhansen: comment and changelog munging.

coco/tdx-host: Expose P-SEAMLDR information via sysfs
TDX module updates require userspace to select the appropriate module to load. Expose necessary information to facilitate this decision. Two values are needed: - P-SEAMLDR version: for compatibility checks between TDX module and P-SEAMLDR - num_remaining_updates: indicates how many updates can be performed Expose them as tdx-host device attributes visible only when updates are supported. Note that the underlying P-SEAMLDR attributes are available regardless of update support; this only restricts their visibility to userspace.

x86/virt/seamldr: Add a helper to retrieve P-SEAMLDR information
P-SEAMLDR reports its state via SEAMLDR.INFO, including its version and the number of remaining runtime updates. This information is useful for userspace. For example, userspace can use the P-SEAMLDR version to determine whether a candidate TDX module is compatible with the running loader, and can use the remaining update count to determine whether another runtime update is still possible. Add a helper to retrieve P-SEAMLDR information in preparation for exposing P-SEAMLDR version and other necessary information to userspace. Export the new kAPI for use by the "tdx_host" device. Note that there are two distinct P-SEAMLDR APIs with similar names: "SEAMLDR.INFO" is metadata about the loader. It's metadata for the update process. "SEAMLDR.SEAMINFO" is metadata about SEAM mode. It is for the module init process, not for the update process. Use SEAMLDR.INFO here. For details, see "Intel Trust Domain Extensions - SEAM Loader (SEAMLDR) Interface Specification".

x86/virt/seamldr: Introduce a wrapper for P-SEAMLDR SEAMCALLs
The TDX architecture uses the "SEAMCALL" instruction to communicate with
SEAM mode software. Right now, the only SEAM mode software that the kernel
communicates with is the TDX module. But, there is actually another
component that runs in SEAM mode but it is separate from the TDX module:
the persistent SEAM loader or "P-SEAMLDR". Right now, the only component
that communicates with it is the BIOS which loads the TDX module itself at
boot. But, to support updating the TDX module, the kernel now needs to be
able to talk to it.
P-SEAMLDR SEAMCALLs differ from TDX module SEAMCALLs in areas such as
concurrency requirements.
Add a P-SEAMLDR wrapper to handle these differences and prepare for
implementing concrete functions.
Use seamcall_prerr() (not '_ret') because current P-SEAMLDR calls do not
use any output registers other than RAX.
Note: Despite the similar name, the NP-SEAMLDR ("Non-Persistent")
(ACM) invoked exclusively by the BIOS at boot rather than a component
running in SEAM mode. The kernel cannot call it at runtime. It exposes
no SEAMCALL interface.

coco/tdx-host: Expose TDX module version
For TDX module updates, userspace needs to select compatible update versions based on the current module version. For example, the 1.5.x series runs on Sapphire Rapids but not Granite Rapids, which needs 2.0.x. Updates are also constrained by version distance, so a 1.5.6 module might permit updates to 1.5.7 but not to 1.5.20. Start the process of punting the version selection logic to userspace. Expose the TDX module version in the new faux device. Define TDX_VERSION_FMT macro for the TDX version format since it will be used multiple times. Also convert an existing print statement to use it. == Background == For posterity, here's what other firmware mechanisms do: 1. AMD SEV leverages an existing PCI device for the PSP to expose metadata. TDX uses a faux device as it doesn't have PCI device in its architecture. 2. Microcode uses per-CPU virtual devices to report microcode revisions because CPUs can have different revisions. But, there is only a single TDX module, so exposing the TDX module version through a global TDX faux device is appropriate 3. ARM's CCA implementation isn't in-tree yet, but will likely follow a similar faux device approach, though it's unclear whether they need to expose firmware version information [ dhansen: trim changelog ] Signed-off-by: Chao Gao <chao.gao@intel.com> Signed-off-by: Dave Hansen <dave.hansen@linux.intel.com> Reviewed-by: Binbin Wu <binbin.wu@linux.intel.com> Reviewed-by: Tony Lindgren <tony.lindgren@linux.intel.com> Reviewed-by: Xu Yilun <yilun.xu@linux.intel.com> Reviewed-by: Kai Huang <kai.huang@intel.com> Reviewed-by: Kiryl Shutsemau (Meta) <kas@kernel.org> Reviewed-by: Xiaoyao Li <xiaoyao.li@intel.com> Reviewed-by: Dave Hansen <dave.hansen@linux.intel.com> Link: https://lore.kernel.org/all/2025073035-bulginess-rematch-b92e@gregkh/ # [1] Link: https://patch.msgid.link/20260520133909.409394-8-chao.gao@intel.com |

coco/tdx-host: Introduce a "tdx_host" device
TDX depends on a platform firmware module that runs on the CPU. Unlike other CoCo architectures, TDX has no hardware "device" running the show, just a blob on the CPU. Create a virtual device to anchor interactions with this platform firmware. This lets later code: - expose metadata: TDX module version, seamldr version, to userspace as device attributes - implement firmware uploader APIs (which are tied to a device) to support TDX module runtime updates Use a faux device because the TDX module is singular within the system and has no platform resources. Using a faux device eliminates the need to create a stub bus. The call to tdx_get_sysinfo() ensures that the TDX module is ready to provide services. Note that AMD has a PCI device for the PSP for SEV and ARM CCA will likely have a faux device [1]. Thanks to Dan and Yilun for all the help on this one.

x86/virt/tdx: Move low level SEAMCALL helpers out of <asm/tdx.h>
TDX host core code implements three seamcall*() helpers to make SEAMCALLs to the TDX module. Currently, they are implemented in <asm/tdx.h> and are exposed to other kernel code which includes <asm/tdx.h>. However, other than the TDX host core, seamcall*() are not expected to be used by other kernel code directly. For instance, for all SEAMCALLs that are used by KVM, the TDX host core exports a wrapper function for each of them. Move seamcall*() and related code out of <asm/tdx.h> and make them only visible to TDX host core. Since TDX host core tdx.c is already very heavy, don't put low level seamcall*() code there but to a new dedicated "seamcall_internal.h". Also, currently tdx.c has seamcall_prerr*() helpers which additionally print error message when calling seamcall*() fails. Move them to "seamcall_internal.h" as well. In such way all low level SEAMCALL helpers are in a dedicated place, which is much more readable.

x86/virt/tdx: Consolidate TDX global initialization states
The kernel uses several global flags to guard one-time TDX initialization flows and prevent them from being repeated. When the TDX module is updated, all of those states must be reset so that the module can be initialized again. Today those states are kept as separate global variables, which makes the reset path awkward and easy to miss when a new state is added. Group the states into a single structure so they can be reset together, for example with memset(), and so a newly added state won't be missed. Drop the __ro_after_init annotation from tdx_module_initialized because the other two states do not have it. And with TDX module update support, all the states need to be writable at runtime.

TDX module global initialization is executed only once. The first call caches both the result and the "done" state, and later callers reuse the saved result. A lock protects that cached states. Those states and the lock are currently kept as function-local statics because they are used only by try_init_module_global(). TDX module updates need to reset the cached states so TDX global initialization can be run again after an update. That will add another access site in the same file.

x86/tdx: Disable the TDX module during kexec and kdump
Use the TDH.SYS.DISABLE SEAMCALL, which disables the TDX module, reclaims all memory resources assigned to TDX, and clears any partial-write induced poison, to allow kexec and kdump on platforms with the partial write errata. On TDX-capable platforms with the partial write erratum, kexec has been disabled because the new kernel could hit a machine check reading a previously poisoned memory location. Later TDX modules support TDH.SYS.DISABLE, which disables the module and reclaims all TDX memory resources, allowing the new kernel to re-initialize TDX from scratch. This operation also clears the old memory, cleaning up any poison. Add tdx_sys_disable() to tdx_shutdown(), which is called in the syscore_shutdown path for kexec. This is done just before tdx_shutdown() disables VMX on all CPUs. For kdump, call tdx_sys_disable() in the crash path before x86_virt_emergency_disable_virtualization_cpu() does VMXOFF. Since this clears any poison on TDX-managed memory, remove the X86_BUG_TDX_PW_MCE check in machine_kexec() that blocked kexec on partial write errata platforms.

x86/virt/tdx: Add SEAMCALL wrapper for TDH.SYS.DISABLE
Some early TDX-capable platforms have an erratum where a partial write to TDX private memory can cause a machine check on a subsequent read. On these platforms, kexec and kdump have been disabled in these cases, because the old kernel cannot safely hand off TDX state to the new kernel. Later TDX modules support the TDH.SYS.DISABLE SEAMCALL, which provides a way to cleanly disable TDX and allow kexec to proceed. The new SEAMCALL has an enumeration bit, but that is ignored. It is expected that users will be using the latest TDX module, and the failure mode for running the missing SEAMCALL on an older module is not fatal. This can be a long running operation, and the time needed largely depends on the amount of memory that has been allocated to TDs. If all TDs have been destroyed prior to the sys_disable call, then it is fast, with only needing to override the TDX module memory. After the SEAMCALL completes, the TDX module is disabled and all memory resources allocated to TDX are freed and reset. The next kernel can then re-initialize the TDX module from scratch via the normal TDX bring-up sequence. The SEAMCALL can return two different error codes that expect a retry. - TDX_INTERRUPTED_RESUMABLE can be returned in the case of a host interrupt. However, it will not return until it makes some forward progress, so we can expect to complete even in the case of interrupt storms. - TDX_SYS_BUSY will be returned on contention with other TDH.SYS.* SEAMCALLs, however a side effect of TDH.SYS.DISABLE is that it will block other SEAMCALLs once it gets going. So this contention will be short lived. So loop infinitely on either of these error codes, until success or other error. An error is printed if the SEAMCALL fails with anything other than the error codes that cause retries, or 'synthesized' error codes produced for #GP or #UD. e.g., an old module that has been properly initialized, that doesn't implement SYS_DISABLE, returns TDX_OPERAND_INVALID. This prints: virt/tdx: TDH.SYS.DISABLE failed: 0xc000010000000000 But a system that doesn't have any TDX support at all doesn't print anything.

x86/virt/tdx: Pull kexec cache flush logic into arch/x86
KVM tries to take care of some required cache flushing earlier in the kexec path in order to be kind to some long standing races that can occur later in the operation. Until recently, VMXOFF was handled within KVM. Since VMX being enabled is required to make a SEAMCALL, it had the best per-cpu scoped operation to plug the flushing into. So it is kicked off from there. This early kexec cache flushing in KVM happens via a syscore shutdown callback. Now that VMX enablement control has moved to arch/x86, which has grown its own syscore shutdown callback, it no longer make sense for it to live in KVM. It fits better with the TDX enablement managing code. In addition, future changes will add a SEAMCALL that happens immediately before VMXOFF, which means the cache flush in KVM will be too late to flush the cache before the last SEAMCALL. So move it to the newly added TDX arch/x86 syscore shutdown handler. Since tdx_cpu_flush_cache_for_kexec() is no longer needed by KVM, make it static and remove the export. Since it is also not part of an operation spread across disparate components, remove the redundant comments and verbose naming. In the existing KVM based code, CPU offline also funnels through tdx_cpu_flush_cache_for_kexec(). Add an explicit WBINVD in tdx_offline_cpu() as well, even though it may be redundant with WBINVD done elsewhere during CPU offline (e.g. hlt_play_dead()). This avoids relying on fragile code ordering for cache coherency safety.

First round of Kbuild fixes for 7.1
- kbuild: builddeb - avoid recompiles for non-cross-compiles
Avoid triggering complete rebuilds for non-cross-compile Debian
package builds by only triggering the rebuild of host tools for
actual cross-compile builds.
- kbuild: Never respect CONFIG_WERROR / W=e to fixdep
Avoid spurious rebuilds of fixdep w/ and w/o -Werror during a single
kbuild invocation by never respecting CONFIG_WERROR for fixdep.

tools/power x86_energy_perf_policy: Enhances SoC Slider related checks
When processor_thermal_soc_slider is loaded, its slider and offset modparams are visible. Check that the driver actually registered the profile named "SoC Slider" before reading or writing these modparams. n.b. This utility allows writing the Slider and Offset modparams even if the driver policy is not "balanced". Currently the processor_thermal_soc_slider consults those modparams only in "balanced" mode.

clk: bcm: rpi: Mark VEC clock as CLK_IGNORE_UNUSED
On Raspberry Pi 3B, the VEC clock is used by the VideoCore firmware
display driver, which remains active until the vc4 driver loads and
sends NOTIFY_DISPLAY_DONE. If this clock is disabled during boot, a bus
lockup happens and the firmware becomes unresponsive, causing a complete
system lockup.
Mark the VEC clock with CLK_IGNORE_UNUSED so it survives the unused
clock disablement and remains available until the vc4 driver takes over
display management.

ring-buffer fix for 7.1:
- Fix accounting of persistent ring buffer rewind On boot up, the head page is moved back to the earliest point of the saved ring buffer. This is because the ring buffer being read by user space on a crash may not save the part it read. Rewinding the head page back to the earliest saved position helps keep those events from being lost. The number of events is also read during boot up and displayed in the stats file in the tracefs directory. It's also used for other accounting as well. On boot up, the "reader page" is accounted for but a rewind may put it back into the buffer and then the reader page may be accounted for again. Save off the original reader page and skip accounting it when scanning the pages in the ring buffer. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaevLRxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qsNBAQCO9T+3kbDLD/DxRBYjeMXhTg2iY2OV SHV9jEzcYTahmwEAqVCFY9sNxVYXait/C924SmHCSi1N0HrIuEzIEd29iwk= =bv+t -----END PGP SIGNATURE----- Merge tag 'trace-ring-buffer-v7.1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ring-buffer fix from Steven Rostedt: - Fix accounting of persistent ring buffer rewind On boot up, the head page is moved back to the earliest point of the saved ring buffer.

Merge tag 'io_uring-7.1-20260424' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux
Pull io_uring fixes from Jens Axboe:
- Fix for a NOMMU bug with io_uring, where NOMMU doesn't grab page refs
at mmap time. NOMMU also has entirely broken FOLL_PIN support, yet
here we are
- A few fixes covering minor issues introduced in this merge window
- data race annotation to shut up KCSAN for when io-wq limits are
applied
- A nospec addition for direct descriptor file updating. Rest of the
direct descriptor path already had this, but for some reason the
update did not. Now they are all the same
- Various minor defensive changes that claude identified and suggested
terrible fixes for, turned into actually useful cleanups:
- Use kvfree() for the imu cache. These can come from kmalloc or
vmalloc depending on size, but the in-cache ones are capped
where it's always kmalloc based. Change to kvfree() in the
cleanup path, making future changes unlikely to mess that up
- Negative kbuf consumption lengths. Can't happen right now, but
cqe->res is used directly, which if other codes changes could
then be an error value
- Fix for an issue with the futex code, where partial wakes on a
vectored fuxes would potentially wake the same futex twice, rather
than move on to the next one. This could confuse an application as it
would've expected the next futex to have been woken
- Fix for a bug with ring resizing, where SQEs or CQEs might not have
been copied correctly if large SQEs or CQEs are used in the ring.
Application side issue, where SQEs or CQEs might have been lost
during resize
- Fix for a bug where EPOLL_URING_WAKE might have been lost, causing a
multishot poll to not be terminated when it's nested, like it should
have been
- Fix for an issue with signed comparison of poll references for the
slow path
- Fix for a user struct UAF in the zcrx code
- Two minor zcrx cleanups
* tag 'io_uring-7.1-20260424' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux:
io_uring: take page references for NOMMU pbuf_ring mmaps

Description for this pull request:
- Fix potential data leakage by zeroing the portion of the straddle block
beyond initialized_size when reading non-resident attributes.
- Remove unnecessary zeroing in ntfs_punch_hole() for ranges beyond
initialized_size, as they are already returned as zeros on read.
- Fix writable check in ntfs_file_mmap_prepare() to correctly handle
shared mappings using VMA_SHARED_BIT | VMA_MAYWRITE_BIT.
- Use page allocation instead of kmemdup() for IOMAP_INLINE data to
ensure page-aligned address and avoid BUG trap in
iomap_inline_data_valid() caused by the page boundary check.
- Add a size check before memory allocation in ntfs_attr_readall() and
reject overly large attributes.
- Remove unneeded noop_direct_IO from ntfs_aops as it is no longer
required following the FMODE_CAN_ODIRECT flag.
- Fix seven static analysis warnings reported by Smatch.

Pull RISC-V updates from Paul Walmsley:
"There is one significant change outside arch/riscv in this pull
request: the addition of a set of KUnit tests for strlen(), strnlen(),
and strrchr().
Otherwise, the most notable changes are to add some RISC-V-specific
string function implementations, to remove XIP kernel support, to add
hardware error exception handling, and to optimize our runtime
unaligned access speed testing.
A few comments on the motivation for removing XIP support. It's been
broken in the RISC-V kernel for months. The code is not easy to
maintain. Furthermore, for XIP support to truly be useful for RISC-V,
we think that compile-time feature switches would need to be added for
many of the RISC-V ISA features and microarchitectural properties that
are currently implemented with runtime patching. No one has stepped
forward to take responsibility for that work, so many of us think it's
best to remove it until clear use cases and champions emerge.
Summary:
- Add Kunit correctness testing and microbenchmarks for strlen(),
strnlen(), and strrchr()
- Add RISC-V-specific strnlen(), strchr(), strrchr() implementations
- Add hardware error exception handling
- Clean up and optimize our unaligned access probe code
- Enable HAVE_IOREMAP_PROT to be able to use generic_access_phys()
- Remove XIP kernel support
- Warn when addresses outside the vmemmap range are passed to
vmemmap_populate()
- Update the ACPI FADT revision check to warn if it's not at least
ACPI v6.6, which is when key RISC-V-specific tables were added to
the specification
- Increase COMMAND_LINE_SIZE to 2048 to match ARM64, x86, PowerPC,
etc.
- Make kaslr_offset() a static inline function, since there's no need
for it to show up in the symbol table
- Add KASLR offset and SATP to the VMCOREINFO ELF notes to improve
kdump support
- Add Makefile cleanup rule for vdso_cfi copied source files, and add
a .gitignore for the build artifacts in that directory
- Remove some redundant ifdefs that check Kconfig macros
- Add missing SPDX license tag to the CFI selftest
- Simplify UTS_MACHINE assignment in the RISC-V Makefile
- Clarify some unclear comments and remove some superfluous comments
- Fix various English typos across the RISC-V codebase"
