2026-06-03kho: add support for linked-block serializationPasha Tatashin2-0/+16
Introduce a linked-block serialization mechanism for state handover. Previously, LUO used contiguous memory blocks for serializing sessions and files, which imposed limits on the total number of items that could be preserved across a live update. This commit adds the infrastructure for a more flexible, block-based approach where serialized data is stored in a chain of linked blocks. This is a generic KHO serialization block infrastructure that can be used by multiple subsystems.

2026-06-03coco/tdx-host: Expose P-SEAMLDR information via sysfsChao Gao1-0/+21
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.

2026-06-03coco/tdx-host: Expose TDX module versionChao Gao1-0/+5
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

2026-06-03arm64: kernel: Disable CNP on HiSilicon HIP09Zeng Heng1-0/+2
HiSilicon HIP09 implements TLB entry matching behavior that deviates from the ARM architecture specification when the CNP (Common not Private) bit is set in TTBRx_ELx. When TTBRx.CNP=1, TLB entries may be incorrectly shared between CPU cores, leading to TLB conflicts and stale mappings. This affects coherency and can result in incorrect translations. Add the hardware erratum workaround (Hisilicon erratum 162100125) to disable CNP on affected HIP09 cores.

2026-06-03dt-bindings: timer: arm,arch_timer: Fix requirements for interrupt descriptionMarc Zyngier1-13/+8
The arm,arch_timer DT binding is extremely imprecise in describing the requirements for interrupts. Follow the architecture by making it explicit that: - the EL1 secure timer irq is required if EL3 is implemented - the EL1 physical timer irq is always required - the EL1 virtual timer irq is always required - the EL2 physical timer irq is required if EL2 is implemented - the EL2 virtual timer irq is required if FEAT_VHE is implemented The consequence of the above is that the minimum number of interrupts to be described is 2, and not 1. Finally, clean up the description which made the assumption that the timers are plugged into a GIC (unfortunately, that's not always true), drop the MMIO nonsense that has long be moved to a separate binding, and use the architectural terminology to describe the various interrupts.

2026-06-03wifi: rtw89: usb: add serial_number and uuid sysfs attributes for 0x28de:0x2432Johnson Tsai1-0/+24
Expose the device's Serial Number (SN) and UUID from EFUSE via two read-only sysfs attributes, `serial_number` and `uuid`, on the ieee80211 phy device under the `rtw89_usb` attribute group. This hardware identification information is essential for user-space applications to uniquely identify, track, and manage specific Wi-Fi adapters. For example, in automated factory provisioning or device management systems, user-space tools rely on the EFUSE serial number and UUID to bind configurations to specific physical adapters. Currently, standard wireless APIs do not expose this low-level hardware information, making these sysfs nodes the only viable solution for user space to extract this data. The attributes are gated behind a new RTW89_QUIRK_HW_INFO_SYSFS quirk, enabled only for the VID 0x28de / PID 0x2432 device via the dev_id_quirks field in rtw89_driver_info.

2026-06-02mm/hugetlb_cma: restrict hugetlb_cma parameter to gigantic-page alignmentSang-Heon Jeon1-0/+4
Existing hugetlb_cma parameter handling logic rejects sizes smaller than one gigantic page, but rounds up larger sizes that are not a multiple of it. The two behaviors are inconsistent and neither is documented. To remove existing inconsistent and undefined behavior, restrict hugetlb_cma parameter to only accept multiples of the gigantic page size. After this restriction, the redundant round_up() in the allocation loop can be removed. The new restriction is also documented in kernel-parameters.txt. Also, including other minor changes for readability improvement with no functional change.

2026-06-02dt-bindings: display: rockchip: analogix-dp: Fix hclk as third clock for RK3588Damon Ding1-1/+39
RK3588 eDP controller requires HCLK_VO1 to access the VO1 GRF registers and enable the video datapath. Previously, the clock was enabled implicitly via the 'rockchip,vo-grf' phandle reference, which allowed the eDP to work without explicitly managing the hclk_vo1 clock. However, this is not safe or explicit. To make the clock dependency explicit, enforce per-SoC clock-names requirements: - RK3288: 2 clocks (dp, pclk) - RK3399: 3 clocks (dp, pclk, grf) - RK3588: 3 clocks (dp, pclk, hclk) Do not reuse the 'grf' clock name for RK3588 because it represents a different clock with distinct control logic: - The 'grf' clock is only for GRF register access and is toggled dynamically during register access. - The 'hclk' clock controls both GRF access and video datapath gating, and must remain enabled during probe.

2026-06-02tracing/eprobes: Allow use of BTF names to dereference pointersSteven Rostedt1-0/+4
Add syntax to the parsing of eprobes to be able to typecast a trace event field that is a pointer to a structure. Currently, a dereference must be a number, where the user has to figure out manually the offset of a member of a structure that they want to dereference. But for event probes that records a field that happens to be a pointer to a structure, it cannot dereference these values with BTF naming, but must use numerical offsets. For example, to find out what device a sk_buff is pointing to in the net_dev_xmit trace event, one must first use gdb to find the offsets of the members of the structures: (gdb) p &((struct sk_buff *)0)->dev $1 = (struct net_device **) 0x10 (gdb) p &((struct net_device *)0)->name $2 = (char (*)[16]) 0x118 And then use the raw numbers to dereference: # echo 'e:xmit net.net_dev_xmit +0x118(+0x10($skbaddr)):string' >> dynamic_events If BTF is in the kernel, then instead, the skbaddr can be typecast to sk_buff and use the normal dereference logic. # echo 'e:xmit net.net_dev_xmit (sk_buff)skbaddr->dev->name:string' >> dynamic_events # echo 1 > events/eprobes/xmit/enable # cat trace [..] sshd-session-1022 [000] b..2. 860.249343: xmit: (net.net_dev_xmit) arg1="enp7s0" sshd-session-1022 [000] b..2. 860.250061: xmit: (net.net_dev_xmit) arg1="enp7s0" sshd-session-1022 [000] b..2. 860.250142: xmit: (net.net_dev_xmit) arg1="enp7s0" sshd-session-1022 [000] b..2. 860.263553: xmit: (net.net_dev_xmit) arg1="enp7s0" sshd-session-1022 [000] b..2. 860.283820: xmit: (net.net_dev_xmit) arg1="enp7s0" sshd-session-1022 [000] b..2. 860.302716: xmit: (net.net_dev_xmit) arg1="enp7s0" sshd-session-1022 [000] b..2. 860.322905: xmit: (net.net_dev_xmit) arg1="enp7s0" sshd-session-1022 [000] b..2. 860.342828: xmit: (net.net_dev_xmit) arg1="enp7s0" sshd-session-1022 [000] b..2. 860.362268: xmit: (net.net_dev_xmit) arg1="enp7s0" sshd-session-1022 [000] b..2. 860.382335: xmit: (net.net_dev_xmit) arg1="enp7s0" sshd-session-1022 [000] b..2. 860.400856: xmit: (net.net_dev_xmit) arg1="enp7s0" sshd-session-1022 [000] b..2. 860.419893: xmit: (net.net_dev_xmit) arg1="enp7s0" The syntax is simply: (STRUCT)(FIELD)->MEMBER[->MEMBER..] Also add comments around the #else and #endif of #ifdef CONFIG_PROBE_EVENTS_BTF_ARGS to know what they are for.
