2025-11-14PCI/TSM: Add 'dsm' and 'bound' attributes for dependent functionsDan Williams
PCI/TSM sysfs for physical function 0 devices, i.e. the "DSM" (Device Security Manager), contains the 'connect' and 'disconnect' attributes. After a successful 'connect' operation the DSM, its dependent functions (SR-IOV virtual functions, non-zero multi-functions, or downstream endpoints of a switch DSM) are candidates for being transitioned into a TDISP (TEE Device Interface Security Protocol) operational state, via pci_tsm_bind(). At present sysfs is blind to which devices are capable of TDISP operation and it is ambiguous which functions are serviced by which DSMs. Add a 'dsm' attribute to identify a function's DSM device, and add a 'bound' attribute to identify when a function has entered a TDISP operational state.

As preparation, the existing Microchip SPI driver is renamed to clearly indicate that it supports only the Microchip PolarFire SoC "hard" controller. Although it was originally named with the expectation that it might also cover the FPGA CoreSPI "soft" IP, the register layouts differ significantly, so separate drivers are required.

2025-11-14VFS: change vfs_mkdir() to unlock on failure.NeilBrown
vfs_mkdir() already drops the reference to the dentry on failure but it leaves the parent locked. This complicates end_creating() which needs to unlock the parent even though the dentry is no longer available. If we change vfs_mkdir() to unlock on failure as well as releasing the dentry, we can remove the "parent" arg from end_creating() and simplify the rules for calling it. Note that cachefiles_get_directory() can choose to substitute an error instead of actually calling vfs_mkdir(), for fault injection. In that case it needs to call end_creating(), just as vfs_mkdir() now does on error. ovl_create_real() will now unlock on error. So the conditional end_creating() after the call is removed, and end_creating() is called internally on error.

2025-11-13KVM: x86: Document a virtualization gap for GIF on AMD CPUsYosry Ahmed
According to the APM Volume #2, Section 15.17, Table 15-10 (24593—Rev. 3.42—March 2024), When "GIF==0", an "Debug exception or trap, due to breakpoint register match" should be "Ignored and discarded". KVM lacks any handling of this. Even when vGIF is enabled and vGIF==0, the CPU does not ignore #DBs and relies on the VMM to do so. Handling this is possible, but the complexity is unjustified given the rarity of using HW breakpoints when GIF==0 (e.g. near VMRUN). KVM would need to intercept the #DB, temporarily disable the breakpoint, singe-step over the instruction (probably reusing NMI singe-stepping), and re-enable the breakpoint. Instead, document this as an erratum.
