tools/ files are compiled in userspace so using types like uint8_t is legitimate. Signed-off-by: Octavian Purdila <[email protected]>
Directly using shift operations in userspace compiled code should not trigger warnings as BIT_ULL macros are not available outside the kernel. Signed-off-by: Octavian Purdila <[email protected]>

This patch calls an architecture hook during the kernel config process that allows the architecture to automatically define kconfig symbols. This can be done by exporting environment variables from the new architecture hook. Signed-off-by: Octavian Purdila <[email protected]>
Adds the LKL Kconfig, vmlinux linker script, basic architecture headers and miscellaneous basic functions or stubs such as dump_stack(), show_regs() and cpuinfo proc ops. The headers we introduce in this patch are simple wrappers to the asm-generic headers or stubs for things we don't support, such as ptrace, DMA, signals, ELF handling and low level processor operations. The kernel configuration is automatically updated to reflect the endianness of the host, 64bit support or the output format for vmlinux's linker script. We do this by looking at the ld's default output format. Signed-off-by: Octavian Purdila <[email protected]>
This patch introduces the host operations that define the interface between the LKL and the host. These operations must be provided either by a host library or by the application itself. Signed-off-by: Octavian Purdila <[email protected]>
LKL is a non MMU architecture and hence there is not much work left to do other than initializing the boot allocator and providing the page and page table definitions. The backstore memory is allocated via a host operation and the memory size to be used is specified when the kernel is started, in the lkl_start_kernel call. Signed-off-by: Octavian Purdila <[email protected]>
LKL does not support user processes but it must support kernel threads as part as the normal kernel work-flow. It uses host operations to create and terminate host threads that are going to run the kernel threads. It also uses semaphores to synchronize those threads and to allow the Linux kernel scheduler to control how the kernel threads run. Each kernel thread runs in a host threads and has a host semaphore associated with it - the thread's scheduling semaphore. The semaphore counter is initialized to 0. The first thing a kernel thread does after getting spawned, before running any kernel code, is to perform a down operation to block the thread. The kernel controls host threads scheduling by performing up and down operations on the scheduling semaphore. In __switch_context an up operation on the next thread is performed to wake up a blocked thread, and a down operation is performed on the prev thread to block it. A thread is terminated by marking it in free_thread_info and performing an up operation on the scheduling semaphore at which point the marked thread will terminate itself. Signed-off-by: Octavian Purdila <[email protected]>
Add APIs that allows the host to reserve and free and interrupt number and also to trigger an interrupt. The trigger operation will simply store the interrupt data in queue. The interrupt handler is run later, at the first opportunity it has to avoid races with any kernel threads. Currently, interrupts are run on the first interrupt enable operation if interrupts are disabled and if we are not already in interrupt context. When triggering an interrupt the host can also send a void pointer that is going to be available to the handler routine via get_irq_regs()->irq_data. This allows to easly create host <-> kernel synchronous communication channels and is currently used by the system call interface. Signed-off-by: Octavian Purdila <[email protected]>
The LKL application API is based on the kernel system call interface in order to offer a stable API to applications. Note that we can't offer the full Linux system call interface due to LKL limitations such as lack of virtual memory, signal, user processes, etc. The host is using the LKL interrupt mechanism (lkl_trigger_irq) to initiate a system call. The system call is executed in the context of the init process. To avoid collisions between the Linux API and the LKL API (e.g. struct stat, MKNOD, etc.) we use a python script to modify the user headers and to prefix all of the global symbols (structures, typedefs, defines) with LKL, lkl, _LKL, _lkl, __LKL or __lkl. Signed-off-by: Octavian Purdila <[email protected]>
Clockevent driver based on host timer operations and clocksource driver and udelay support based on host time operations. Signed-off-by: Octavian Purdila <[email protected]>
All memory mapped I/O access is redirected to the host via the iomem_access host operation. The host can setup the memory mapped I/O region via the ioremap operation. This allows the host to implement support for various devices, such as block or network devices. Signed-off-by: Octavian Purdila <[email protected]>
Write operations are deferred to the host print operation. Signed-off-by: Octavian Purdila <[email protected]>
This is needed for arch/lkl where where execve can not be implemented and init only runs in kernel space. Signed-off-by: Octavian Purdila <[email protected]>
Add the lkl_start_kernel and lkl_sys_halt APIs that start and respectively stops the Linux kernel. lkl_start_kernel creates a separate threads that will run the initial and idle kernel thread. It waits for the kernel to complete initialization before returning, to avoid races with system calls issues by the host application. During the setup phase, we create "/init" in initial ramfs root filesystem to avoid mounting the "real" rootfs since ramfs is good enough for now. lkl_stop_kernel will shutdown the kernel, terminate all threads and free all host resources used by the kernel before returning. This patch also introduces idle CPU handling since it is closely related to the shutdown process. A host semaphore is used to wait for new interrupts when the kernel switches the CPU to idle to avoid wasting host CPU cycles. When the kernel is shutdown we terminate the idle thread at the first CPU idle event. Signed-off-by: Octavian Purdila <[email protected]>
Basic Makefiles for building LKL. Add a new architecture specific target for installing the resulting library files and headers. Signed-off-by: Octavian Purdila <[email protected]>
This patch adds the skeleton for the host library, tests and application examples. The host library is implementing the host operations needed by LKL and is split into host dependent (depends on a specific host, e.g. POSIX hosts) and host independent parts (will work on all supported hosts). Signed-off-by: Octavian Purdila <[email protected]>
Add basic utility functions for getting a string from a kernel error code and a fprintf like function that uses the host print operation. The latter is useful for informing the user about errors that occur in the host library. Signed-off-by: Octavian Purdila <[email protected]>
This patch adds helpers for implementing the memory mapped I/O host operations that can be used by code that implements host devices. Generic host operations for lkl_ioremap and lkl_iomem_access are provided that allows multiplexing multiple I/O memory mapped regions. The host device code can create a new memory mapped I/O region with register_iomem(). Read and write access functions need to be provided by the caller. Signed-off-by: Octavian Purdila <[email protected]>
Add helpers for implementing host virtio devices. It uses the memory mapped I/O helpers to interact with the Linux MMIO virtio transport driver and offers support to setup and add a new virtio device, dispatch requests from the incoming queues as well as support for completing requests. All added virtio devices are stored in lkl_virtio_devs as strings, per the Linux MMIO virtio transport driver command line specification. Signed-off-by: Octavian Purdila <[email protected]>
Host independent implementation for virtio block devices. The host dependent part of the host library must provide an implementation for lkl_dev_block_ops. Disks can be added to the LKL configuration via lkl_disk_add(), a new LKL application API. Signed-off-by: Octavian Purdila <[email protected]>
Add LKL applications APIs to mount and unmount a filesystem from a disk added via lkl_disk_add(). Also add open/close/read directory wrappers on top of lkl_sys_getdents64. Signed-off-by: Octavian Purdila <[email protected]>
Implement LKL host operations for POSIX hosts. Signed-off-by: Octavian Purdila <[email protected]>
Add a simple LKL test applications that starts the kernel and performs simple tests that minimally exercise the LKL API. Signed-off-by: Octavian Purdila <[email protected]>

Some architectures needs customized rodata section names (e.g. lkl for Windows host). Allow them to set the rodata section name. Signed-off-by: Octavian Purdila <[email protected]>
This patch allows LKL to be compiled for windows hosts with the mingw toolchain. Note that patches [1] that fix weak symbols linking are required to successfully compile LKL with mingw. The patch disables the modpost pass over vmlinux since modpost only works with ELF objects. It also adds and workaround to an #include_next <stdard.h> error which is apparently caused by using -nosdtinc. [1] https://sourceware.org/ml/binutils/2015-10/msg00234.html Signed-off-by: Octavian Purdila <[email protected]>
Add host operations for Windows host and virtio disk support. Trivial changes to the generic virtio host code are made since mingw %p format is different then what the MMIO virtion driver expects. The boot test is updated to support Window hosts as well. Signed-off-by: Octavian Purdila <[email protected]>

[ Upstream commit 17122c0 ] Treat any exception during instruction decode for EMULTYPE_SKIP as a "full" emulation failure, i.e. signal failure instead of queuing the exception. When decoding purely to skip an instruction, KVM and/or the CPU has already done some amount of emulation that cannot be unwound, e.g. on an EPT misconfig VM-Exit KVM has already processeed the emulated MMIO. KVM already does this if a #UD is encountered, but not for other exceptions, e.g. if a #PF is encountered during fetch. In SVM's soft-injection use case, queueing the exception is particularly problematic as queueing exceptions while injecting events can put KVM into an infinite loop due to bailing from VM-Enter to service the newly pending exception. E.g. multiple warnings to detect such behavior fire: ------------[ cut here ]------------ WARNING: CPU: 3 PID: 1017 at arch/x86/kvm/x86.c:9873 kvm_arch_vcpu_ioctl_run+0x1de5/0x20a0 [kvm] Modules linked in: kvm_amd ccp kvm irqbypass CPU: 3 PID: 1017 Comm: svm_nested_soft Not tainted 6.0.0-rc1+ torvalds#220 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 RIP: 0010:kvm_arch_vcpu_ioctl_run+0x1de5/0x20a0 [kvm] Call Trace: kvm_vcpu_ioctl+0x223/0x6d0 [kvm] __x64_sys_ioctl+0x85/0xc0 do_syscall_64+0x2b/0x50 entry_SYSCALL_64_after_hwframe+0x46/0xb0 ---[ end trace 0000000000000000 ]--- ------------[ cut here ]------------ WARNING: CPU: 3 PID: 1017 at arch/x86/kvm/x86.c:9987 kvm_arch_vcpu_ioctl_run+0x12a3/0x20a0 [kvm] Modules linked in: kvm_amd ccp kvm irqbypass CPU: 3 PID: 1017 Comm: svm_nested_soft Tainted: G W 6.0.0-rc1+ torvalds#220 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 RIP: 0010:kvm_arch_vcpu_ioctl_run+0x12a3/0x20a0 [kvm] Call Trace: kvm_vcpu_ioctl+0x223/0x6d0 [kvm] __x64_sys_ioctl+0x85/0xc0 do_syscall_64+0x2b/0x50 entry_SYSCALL_64_after_hwframe+0x46/0xb0 ---[ end trace 0000000000000000 ]--- Fixes: 6ea6e84 ("KVM: x86: inject exceptions produced by x86_decode_insn") Signed-off-by: Sean Christopherson <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Sasha Levin <[email protected]>
