System firmware must meet pre-bootDMA protection requirementsand set appropriate flags in ACPI tables to enableKernel DMA Protection. For more information, see Kernel DMA Protection (Memory Access Protection) for OEMs. You need to havevirtualization extension, IOMMU,andDynamic Root of Trust for Measu...
If you want to enable Windows Defender Credential Guard from Windows Registry, then follow these steps. Note that these steps are a little different from the ones given above to disable the feature, as it involves an additional Registry value. ...
The kernel does not launch any other processes itself; this is done by BUP itself, as well as a separate LOADMGR module, which we will discuss later. The purpose of BUP (BringUP platform) is to initialize the entire hardware environment of the platform (including the processor), perform ...

In the Linux kernel code, I have found following api which reset the secondary bus according to the PCIe standard and then wait for secondary bus to be ready again: void pci_reset_secondary_bus(struct pci_dev *dev) { u16 ctrl; pci_read_config_word(dev, PCI_BRIDGE_CONTROL, &ctrl); ct...
The/proc/sys/net/ipv4/tcp_memparameter defaults are calculated at boot time from the amount of available memory. At boot time, the kernel will check the available memory in the system, and based on the available memory kernel will assign the/proc/sys/net/ipv4/tcp_memvalue. ...
Secured-core PCs provide powerhouse protection out of the box, with capabilities such as Virtualization-Based Security, Credential Guard, and Kernel DMA protection. The subsequent automation and out-of-the-box capabilities also fre...
Enable interrupt Offcourse it is usually done at very first moment during cpu initialization sequence, but you could also made declaration of some pre-kernel functions for custom ISRs so when kernel reach allocation process, it sees that some of interrupts are already reserved and allocated by ...
I simply merged the btintel folder into my 5.10.35 kernel and added an Intel firmware folder to my system. It seems there's another software that is loaded by the btintel driver: /lib/firmware/intel/ibt-0041-0041.sfi.With this patches in place I am currently able to enable blu...
