reliable alternative technologies are essential. One possible alternative technique is to force the protection of SMEP to fail (change the bit in the CR4 register) through the drop-down programming. This method must ensure that the stack is controllable. This method was previously proposed in some papers and speeches. Another possible alternative is to disable SMEP within the space unit of the Memory Page. This method is achieved through the page-lev

physical memory, it is cleared by the Memory Manager. This bit is set when you access this page or page, and the processor does not automatically clear this bit. Only software can clear it Both a-bit and D-bit are used by the memory management program to manage pages and page tables for switching from the physical memory. PS bit determines the page size PS = 0 the page size is 4 kb, and PDE points to the page table Pat: select the PAT (page Attribute Table) entry. G indicates the global page.

available under CPL = 0. Both commands depend on the hardware status of the processor monitor. The monitor hardware can be equipped (by executing the monitor command) or triggered (depending on various events, the monitor hardware is in the triggered State ). If the monitor hardware is in a triggered state when mwait is executed, mwait acts like a NOP and continues to execute the next command in the stream. The status architecture of the monitor hardware is invisible unless it is performed thro

the corresponding physical address, while macro _ va converts the physical address. The global directory of the main kernel page is still saved in the swapper_pg_dir variable. It is initialized by the paging_init () function. This function performs the following operations:1. Call pagetable_init () to properly create a page table item.2. Write the physical IP address of swapper_pg_dir to the control register of S3.3. If the CPU supports PAE and the kernel supports PAE during compilation, set th

General Method of touch screen Calibration The following formula is used to implement touch screen correction.

inductance L represents the inherent characteristics of the coil and is irrelevant to the current size. Except for the special Inductance Coil (color-coded inductance), the inductance volume is generally not specifically labeled on the coil, but with a specific name.2. Inductive strength XLThe Inductance Coil blocks the AC current. The Inductance Coil is measured in ohm. The relationship between it and inductance L and AC frequency f is XL = 2 π fl3.
