2025-09-24KVM: arm64: selftests: Remove a duplicate register listing in set_id_regsMark Brown
Currently we list the main set of registers with bits we test three times, once in the test_regs array which is used at runtime, once in the guest code and once in a list of ARRAY_SIZE() operations we use to tell kselftest how many tests we plan to execute. This is needlessly fiddly, when adding new registers as the test_cnt calculation is formatted with two registers per line. Instead count the number of bitfields in the register arrays at runtime. The existing code subtracts ARRAY_SIZE(test_regs) from the number of tests to account for the terminating FTR_REG_END entries in the per register arrays, the new code accounts for this when enumerating.

2025-09-24KVM: arm64: selftests: Cope with arch silliness in EL2 selftestOliver Upton
Implementations without FEAT_FGT aren't required to trap the entire ID register space when HCR_EL2.TID3 is set. This is a terrible idea, as the hypervisor may need to advertise the absence of a feature to the VM using a negative value in a signed field, FEAT_E2H0 being a great example of this. Cope with uncooperative implementations in the EL2 selftest by accepting a zero value when FEAT_FGT is absent and otherwise only tolerating the expected nonzero value.

2025-09-24KVM: arm64: selftests: Alias EL1 registers to EL2 counterpartsOliver Upton
FEAT_VHE has the somewhat nice property of implicitly redirecting EL1 register aliases to their corresponding EL2 representations when E2H=1. Unfortunately, there's no such abstraction for userspace and EL2 registers are always accessed by their canonical encoding. Introduce a helper that applies EL2 redirections to sysregs and use aggressive inlining to catch misuse at compile time. Go a little past the architectural definition for ease of use for test authors (e.g. the stack pointer).

But tegra_pcie_ep_raise_msi_irq() incorrectly uses the interrupt number as the MSI vector.

2025-09-24Merge patch series "Add generated modalias to modules.builtin.modinfo"Nathan Chancellor
Alexey Gladkov says: The modules.builtin.modinfo file is used by userspace (kmod to be specific) to get information about builtin modules. Among other information about the module, information about module aliases is stored. This is very important to determine that a particular modalias will be handled by a module that is inside the kernel. There are several mechanisms for creating modalias for modules: The first is to explicitly specify the MODULE_ALIAS of the macro. In this case, the aliases go into the '.modinfo' section of the module if it is compiled separately or into vmlinux.o if it is builtin into the kernel. The second is the use of MODULE_DEVICE_TABLE followed by the use of the modpost utility. In this case, vmlinux.o no longer has this information and does not get it into modules.builtin.modinfo. For example: $ modinfo pci:v00008086d0000A36Dsv00001043sd00008694bc0Csc03i30 modinfo: ERROR: Module pci:v00008086d0000A36Dsv00001043sd00008694bc0Csc03i30 not found. $ modinfo xhci_pci name: xhci_pci filename: (builtin) license: GPL file: drivers/usb/host/xhci-pci description: xHCI PCI Host Controller Driver The builtin module is missing alias "pci:v*d*sv*sd*bc0Csc03i30*" which will be generated by modpost if the module is built separately. To fix this it is necessary to add the generated by modpost modalias to modules.builtin.modinfo. Fortunately modpost already generates .vmlinux.export.c for exported symbols. It is possible to add `.modinfo` for builtin modules and modify the build system so that `.modinfo` section is extracted from the intermediate vmlinux after modpost is executed.

2025-09-24modpost: Create modalias for builtin modulesAlexey Gladkov
For some modules, modalias is generated using the modpost utility and the section is added to the module file. When a module is added inside vmlinux, modpost does not generate modalias for such modules and the information is lost. As a result kmod (which uses modules.builtin.modinfo in userspace) cannot determine that modalias is handled by a builtin kernel module. $ cat /sys/devices/pci0000:00/0000:00:14.0/modalias pci:v00008086d0000A36Dsv00001043sd00008694bc0Csc03i30 $ modinfo xhci_pci name: xhci_pci filename: (builtin) license: GPL file: drivers/usb/host/xhci-pci description: xHCI PCI Host Controller Driver Missing modalias "pci:v*d*sv*sd*bc0Csc03i30*" which will be generated by modpost if the module is built separately. To fix this it is necessary to generate the same modalias for vmlinux as for the individual modules. Fortunately '.vmlinux.export.o' is already generated from which '.modinfo' can be extracted in the same way as for vmlinux.o.
