Static Public Member Functions

static Utcb * myutcb (unsigned long esp=0)
 Get the UTCB pointer from the top of the stack, which is laid out as follows:
static phy_cpu_no mycpu ()
 Return my CPU number.
static void revoke_all_mem (void *address, unsigned long size, unsigned rights, bool myself)
 Revoke all memory for a given virtual region.
static Crd request_mapping (char *start, unsigned long size, unsigned long hotspot)

Detailed Description

A simple program that allows to get the UTCB pointer from the stack.

Member Function Documentation

static phy_cpu_no BaseProgram::mycpu ( )
inlinestatic

Return my CPU number.

static Utcb* BaseProgram::myutcb ( unsigned long  esp = 0)
inlinestatic

Get the UTCB pointer from the top of the stack, which is laid out as follows:

  • 4: UTCB
  • 8: dummy -12: UTCB -16: TLS -20: function pointer

This layout is chosen to make the stack 16-byte aligned.

static Crd BaseProgram::request_mapping ( char *  start,
unsigned long  size,
unsigned long  hotspot 
)
inlinestatic

Request the mapping for a memory area.

static void BaseProgram::revoke_all_mem ( void *  address,
unsigned long  size,
unsigned  rights,
bool  myself 
)
inlinestatic

Revoke all memory for a given virtual region.
