/**
* @defgroup control_registers \
* Control registers
*
* Control registers (CR0, CR1, CR2, CR3, and CR4) determine operating mode of the processor and the characteristics of the
* currently executing task. These registers are 32 bits in all 32-bit modes and compatibility mode.
* In 64-bit mode, control registers are expanded to 64 bits. The MOV CRn instructions are used to manipulate the register
* bits. Operand-size prefixes for these instructions are ignored. The following is also true:
* - The control registers can be read and loaded (or modified) using the move-to-or-from-control-registers forms of the
* MOV instruction. In protected mode, the MOV instructions allow the control registers to be read or loaded (at privilege
* level 0 only). This restriction means that application programs or operating-system procedures (running at privilege
* levels 1, 2, or 3) are prevented from reading or loading the control registers.
* - Bits 63:32 of CR0 and CR4 are reserved and must be written with zeros. Writing a nonzero value to any of the upper 32
* bits results in a general-protection exception, \#GP(0).
* - All 64 bits of CR2 are writable by software.
* - Bits 51:40 of CR3 are reserved and must be 0.
* - The MOV CRn instructions do not check that addresses written to CR2 and CR3 are within the linear-address or
* physical-address limitations of the implementation.
* - Register CR8 is available in 64-bit mode only. The control registers are summarized below, and each architecturally
* defined control field in these control registers is described individually.
* - CR0 - Contains system control flags that control operating mode and states of the processor.
* - CR1 - Reserved.
* - CR2 - Contains the page-fault linear address (the linear address that caused a page fault).
* - CR3 - Contains the physical address of the base of the paging-structure hierarchy and two flags (PCD and PWT). Only
* the most-significant bits (less the lower 12 bits) of the base address are specified; the lower 12 bits of the address
* are assumed to be 0. The first paging structure must thus be aligned to a page (4-KByte) boundary. The PCD and PWT flags
* control caching of that paging structure in the processor's internal data caches (they do not control TLB caching of
* page-directory information). When using the physical address extension, the CR3 register contains the base address of
* the page-directorypointer table. In IA-32e mode, the CR3 register contains the base address of the PML4 table.
* - CR4 - Contains a group of flags that enable several architectural extensions, and indicate operating system or
* executive support for specific processor capabilities.
* - CR8 - Provides read and write access to the Task Priority Register (TPR). It specifies the priority threshold value
* that operating systems use to control the priority class of external interrupts allowed to interrupt the processor. This
* register is available only in 64-bit mode. However, interrupt filtering continues to apply in compatibility mode.
*

* every task switch and tests it when executing x87 FPU/MMX/SSE/SSE2/SSE3/SSSE3/SSE4 instructions.
* - If the TS flag is set and the EM flag (bit 2 of CR0) is clear, a device-not-available exception (\#NM) is raised prior
* to the execution of any x87 FPU/MMX/SSE/SSE2/SSE3/SSSE3/SSE4 instruction; with the exception of PAUSE, PREFETCHh,

* - If the TS flag is set and the MP flag (bit 1 of CR0) and EM flag are clear, an \#NM exception is not raised prior to
* the execution of an x87 FPU WAIT/FWAIT instruction.
* - If the EM flag is set, the setting of the TS flag has no effect on the execution of x87
* FPU/MMX/SSE/SSE2/SSE3/SSSE3/SSE4 instructions.
* The processor does not automatically save the context of the x87 FPU, XMM, and MXCSR registers on a task switch.
* Instead, it sets the TS flag, which causes the processor to raise an \#NM exception whenever it encounters an x87
* FPU/MMX/SSE/SSE2/SSE3/SSSE3/SSE4 instruction in the instruction stream for the new task (with the exception of the
* instructions listed above).
* The fault handler for the \#NM exception can then be used to clear the TS flag (with the CLTS instruction) and save
* the context of the x87 FPU, XMM, and MXCSR registers. If the task never encounters an x87
* FPU/MMX/SSE/SSE2/SSE3/SSSE3/SSE4 instruction, the x87 FPU/MMX/SSE/SSE2/SSE3/SSSE3/SSE4 context is never saved.

*
* A logical processor uses 4-level paging if CR0.PG = 1, CR4.PAE = 1, and IA32_EFER.LME = 1. With 4-level paging, linear
* address are translated using a hierarchy of in-memory paging structures located using the contents of CR3. 4-level
* paging translates 48-bit linear addresses to 52-bit physical addresses. Although 52 bits corresponds to 4 PBytes, linear
* addresses are limited to 48 bits; at most 256 TBytes of linear-address space may be accessed at any given time.
* 4-level paging uses a hierarchy of paging structures to produce a translation for a linear address. CR3 is used to
* locate the first paging-structure, the PML4 table. Use of CR3 with 4-level paging depends on whether processcontext
* identifiers (PCIDs) have been enabled by setting CR4.PCIDE.

*
* @remarks Registers are 32 bits, 64 bits, or 256 bits in width; all are aligned on 128-bit boundaries. All 32-bit

* of less than 32 bits to some of the APIC registers. This is model specific behavior and is not guaranteed to work on all
* processors. Any FP/MMX/SSE access to an APIC register, or any access that touches bytes 4 through 15 of an APIC register
* may cause undefined behavior and must not be executed. This undefined behavior could include hangs, incorrect results or
* unexpected exceptions, including machine checks, and may vary between implementations. Wider registers (64-bit or
* 256-bit) must be accessed using multiple 32-bit loads or stores, with all accesses being 128-bit aligned.

/**
* @brief Write-back (WB)
*
* Writes and reads to and from system memory are cached. Reads come from cache lines on cache hits; read misses cause
* cache fills. Speculative reads are allowed. Write misses cause cache line fills (in processor families starting with the
* P6 family processors), and writes are performed entirely in the cache, when possible. Write combining is allowed. The
* write-back memory type reduces bus traffic by eliminating many unnecessary writes to system memory. Writes to a cache
* line are not immediately forwarded to system memory; instead, they are accumulated in the cache. The modified cache
* lines are written to system memory later, when a write-back operation is performed. Write-back operations are triggered
* when cache lines need to be deallocated, such as when new cache lines are being allocated in a cache that is already
* full. They also are triggered by the mechanisms used to maintain cache consistency. This type of cache-control provides
* the best performance, but it requires that all devices that access system memory on the system bus be able to snoop
* memory accesses to insure system memory and cache coherency.

/**
* @brief Uncacheable (UC-)
*
* Has same characteristics as the strong uncacheable (UC) memory type, except that this memory type can be overridden by
* programming the MTRRs for the WC memory type. This memory type is available in processor families starting from the
* Pentium III processors and can only be selected through the PAT.
