TPM2_Unseal[1] expects the handle of a loaded data object, and not the handle of the parent key. But the tpm2_unseal_cmd provides the parent keyhandle instead of blob_handle for the session HMAC calculation. This causes unseal to fail. Fix this by passing blob_handle to tpm_buf_append_name().

The ASUS Zenbook UX425QA_UM425QA fails to initialize the keyboard after a cold boot. A quirk already exists for "ZenBook UX425", but some Zenbooks report "Zenbook" with a lowercase 'b'. Since DMI matching is case-sensitive, the existing quirk is not applied to these "extra special" Zenbooks. Testing confirms that this model needs the same quirks as the ZenBook UX425 variants.

These only apply to RV32 systems and are related to the 64-bit timer compare value being split across two separate 32-bit registers. We weren't using the appropriate three-write sequence, documented in the RISC-V ISA specifications, to avoid spurious timer interrupts during the update sequence; so, these patches now use the recommended sequence. This doesn't affect 64-bit RISC-V systems, since the timer compare value fits inside a single register and can be updated with a single write. - Fix the RISC-V timer compare register update sequence on RV32 systems to use the recommended sequence in the RISC-V ISA manual This avoids spurious interrupts during updates - Add a dependence on the new CONFIG_CACHEMAINT_FOR_DMA Kconfig symbol for Renesas and StarFive RISC-V SoCs - Add a temporary workaround for a Clang compiler bug caused by using asm_goto_output for get_user() - Clarify our documentation to specifically state a particular ISA specification version for a chapter number reference" * tag 'riscv-for-linus-6.19-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: Add intermediate cast to 'unsigned long' in __get_user_asm riscv: Use 64-bit variable for output in __get_user_asm soc: renesas: Fix missing dependency on new CONFIG_CACHEMAINT_FOR_DMA riscv: ERRATA_STARFIVE_JH7100: Fix missing dependency on new CONFIG_CACHEMAINT_FOR_DMA riscv: suspend: Fix stimecmp update hazard on RV32 riscv: kvm: Fix vstimecmp update hazard on RV32 riscv: clocksource: Fix stimecmp update hazard on RV32 Documentation: riscv: uabi: Clarify ISA spec version for canonical order

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix a crash with passing a stacktrace between synthetic events A synthetic event is an event that combines two events into a single event that can display fields from both events as well as the time delta that took place between the events. It can also pass a stacktrace from the first event so that it can be displayed by the synthetic event (this is useful to get a stacktrace of a task scheduling out when blocked and recording the time it was blocked for). A synthetic event can also connect an existing synthetic event to another event. An issue was found that if the first synthetic event had a stacktrace as one of its fields, and that stacktrace field was passed to the new synthetic event to be displayed, it would crash the kernel. This was due to the stacktrace not being saved as a stacktrace but was still marked as one. When the stacktrace was read, it would try to read an array but instead read the integer metadata of the stacktrace and dereferenced a bad value. Fix this by saving the stacktrace field as a stacktrace. - Fix possible overflow in cmp_mod_entry() compare function A binary search is used to find a module address and if the addresses are greater than 2GB apart it could lead to truncation and cause a bad search result. Use normal compares instead of a subtraction between addresses to calculate the compare value. - Fix output of entry arguments in function graph tracer Depending on the configurations enabled, the entry can be two different types that hold the argument array. The macro FGRAPH_ENTRY_ARGS() is used to find the correct arguments from the given type. One location was missed and still referenced the arguments directly via entry->args and could produce the wrong value depending on how the kernel was configured. - Fix memory leak in scripts/tracepoint-update build tool If the array fails to allocate, the memory for the values needs to be freed and was not. Free the allocated values if the array failed to allocate. * tag 'trace-v6.19-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: scripts/tracepoint-update: Fix memory leak in add_string() on failure function_graph: Fix args pointer mismatch in print_graph_retval() tracing: Avoid possible signed 64-bit truncation tracing: Fix crash on synthetic stacktrace field usage

2026-01-24gpu: nova-core: align LibosMemoryRegionInitArgument size to page sizeAlexandre Courbot2-5/+17
On Turing and GA100 (i.e. the versions that use Libos v2), GSP-RM insists that the 'size' parameter of the LibosMemoryRegionInitArgument struct be aligned to 4KB. The logging buffers are already aligned to that size, so only the GSP_ARGUMENTS_CACHED struct needs to be adjusted. Make that adjustment by adding padding to the end of the struct.

2026-01-24gpu: nova-core: Add basic Turing HALTimur Tabi3-0/+97
Add the basic HAL for recognizing Turing GPUs. This isn't enough to support booting GSP-RM on Turing, but it's a start. Note that GA100, which boots using the same method as Turing, is not supported yet.

2026-01-24gpu: nova-core: rename Imem to ImemSecureTimur Tabi3-14/+20
Rename FalconMem::Imem to ImemSecure to indicate that it references Secure Instruction Memory. This change has no functional impact. On Falcon cores, pages in instruction memory can be tagged as Secure or Non-Secure. For GA102 and later, only Secure is used, which is why FalconMem::Imem seems appropriate. However, Turing firmware images can also contain non-secure sections, and so FalconMem needs to support that. By renaming Imem to ImemSec now, future patches for Turing support will be simpler. Nouveau uses the term "IMEM" to refer both to the Instruction Memory block on Falcon cores as well as to the images of secure firmware uploaded to part of IMEM. OpenRM uses the terms "ImemSec" and "ImemNs" instead, and uses "IMEM" just to refer to the physical memory device. Renaming these terms allows us to align with OpenRM, avoid confusion between IMEM and ImemSec, and makes future patches simpler.
