x86

Implemented By

x86-486sx, x86-hammer, x86-p2, x86-p4

Description

The x86 interface allows certain processor pins to be set/cleared. It is also used by the apic for the startup IPI.

typedef enum {
        Pin_Init,
        Pin_Smi,
        Pin_Nmi,
        Pin_Ignne
} x86_pin_t;

typedef struct {
        void (*set_pin_status)(conf_object_t *obj, x86_pin_t pin, int status);
        void (*start_up)(conf_object_t *obj, uint32 start_address);

Command Descriptions

<x86>.memory-configuration

Synopsis

<x86>.memory-configuration

Description

Print the processors memory configuration. Depending on the processor type, this may include MTRR information, HyperTransport routing information, DRAM configuration, and other memory configuration related information.

<x86>.msrs

Synopsis

<x86>.msrs

Description

Print model specific registers. MSRs not included in the output are either not supported, not implemented, read-only, or must be accessed through other attributes.

<x86>.pregs-fpu

Synopsis

<x86>.pregs-fpu [-f] [-x] [-i] [-b]

Description

Prints the x87 floating-point registers.
This command takes one of the formatting flags -f, -x, or -i.
The -f flag prints the floating-point values of the registers. The -x flag prints the contents of the registers as hexadecimal integers. The -i flag prints the contents of the registers as decimal integers. With the -b flag, the registers are printed in binary floating point form.

<x86>.pregs-sse

Synopsis

<x86>.pregs-sse [-s] [-d] [-f] [-x] [-i] [-b]

Description

Prints the contents of the SSE registers.
This command can take one subregister size flag and one formatting flag.
The subregister size is selected using the either the -s flag (32-bit), or the -d flag (64-bit).
The formatting flags -f, -x, and -i select the formatting of the output. The -f flag prints the floating-point values of the registers as decimal numbers. The -x flag prints the contents of the registers as hexadecimal integers. The -i flag prints the contents of the registers as decimal integers. With the -b flag, the registers are printed in binary floating point form.

<x86>.print-gdt

Synopsis

<x86>.print-gdt

Description

Print all descriptors in the Global Descriptor Table (GDT). Only usable in protected mode.

<x86>.print-idt

Synopsis

<x86>.print-idt

Description

Print all descriptors in the Interrupt Descriptor Table (IDT).
