WebThe KVM_RUN ioctl (cf.) communicates with userspace via a shared memory region. This ioctl returns the size of that region. See the KVM_RUN documentation for details. Besides the size of the KVM_RUN communication region, other areas of the VCPU file descriptor can be mmap-ed, including: WebDecoding I/O Control Codes . It is often difficult to correlate a given 32-bit value to the name assigned to it. That’s because the values are determined at compile time via the macro in the WDK at ntddk.h, ntifs.h, wdm.h and devioctl.h as:

WebFirst things first, let’s clear up the names, because the kernel internals, libdrm and the ioctls are all named differently: GET_UNIQUE ioctl, implemented by drm_getunique is wrapped up in libdrm through the drmGetBusid function. The libdrm drmSetBusid function is backed by the SET_UNIQUE ioctl. Web6 jul. 2024 · My assumption is that sysfs is built using ioctl queries, meaning all the information you would want (or at least most of it) is already available by simply reading files on sysfs.

WebThe ioctl caller must either: i) For a CPU context, set CPU affinity to the correct CPU. Note, obviously that would not need to be done for system-wide tracing on all CPUs. It would also only need to be done for the period of tracing when the ioctl is to be used. ii) Use an event opened for the current process on all CPUs. dick\\u0027s sporting goods west des moines
