STRUCT KGDB_ARCH(9) Kernel Debugger Internals STRUCT KGDB_ARCH(9)NAME
struct_kgdb_arch - Describe architecture specific values.
SYNOPSIS
struct kgdb_arch {
unsigned char gdb_bpt_instr[BREAK_INSTR_SIZE];
unsigned long flags;
int (* set_breakpoint) (unsigned long, char *);
int (* remove_breakpoint) (unsigned long, char *);
int (* set_hw_breakpoint) (unsigned long, int, enum kgdb_bptype);
int (* remove_hw_breakpoint) (unsigned long, int, enum kgdb_bptype);
void (* disable_hw_break) (struct pt_regs *regs);
void (* remove_all_hw_break) (void);
void (* correct_hw_break) (void);
void (* enable_nmi) (bool on);
};
MEMBERS
gdb_bpt_instr[BREAK_INSTR_SIZE]
The instruction to trigger a breakpoint.
flags
Flags for the breakpoint, currently just KGDB_HW_BREAKPOINT.
set_breakpoint
Allow an architecture to specify how to set a software breakpoint.
remove_breakpoint
Allow an architecture to specify how to remove a software breakpoint.
set_hw_breakpoint
Allow an architecture to specify how to set a hardware breakpoint.
remove_hw_breakpoint
Allow an architecture to specify how to remove a hardware breakpoint.
disable_hw_break
Allow an architecture to specify how to disable hardware breakpoints for a single cpu.
remove_all_hw_break
Allow an architecture to specify how to remove all hardware breakpoints.
correct_hw_break
Allow an architecture to specify how to correct the hardware debug registers.
enable_nmi
Manage NMI-triggered entry to KGDB

STRUCT IRQ_DATA(9) Structures STRUCT IRQ_DATA(9)NAME
struct_irq_data - per irq and irq chip data passed down to chip functions
SYNOPSIS
struct irq_data {
unsigned int irq;
unsigned long hwirq;
unsigned int node;
unsigned int state_use_accessors;
struct irq_chip * chip;
struct irq_domain * domain;
void * handler_data;
void * chip_data;
struct msi_desc * msi_desc;
cpumask_var_t affinity;
};
MEMBERS
irq
interrupt number
hwirq
hardware interrupt number, local to the interrupt domain
node
node index useful for balancing
state_use_accessors
status information for irq chip functions. Use accessor functions to deal with it
chip
low level interrupt hardware access
domain
Interrupt translation domain; responsible for mapping between hwirq number and linux irq number.
handler_data
per-IRQ data for the irq_chip methods
chip_data
platform-specific per-chip private data for the chip methods, to allow shared chip implementations
msi_desc
MSI descriptor
affinity
IRQ affinity on SMP
DESCRIPTION
The fields here need to overlay the ones in irq_desc until we cleaned up the direct references and switched everything over to irq_data.

Any one tried puting breakpoint while debugging a core file? I have been using a gdb for running it.. But unsuccessful to put a breakpoint before executing it. Any sugestion or tool for doing it would be welcomed..
Thanks :) (0 Replies)
helo i have asked in exam what that what is the base type of
enum
options are given bewlo
(1) long int
(2) short int
(3) signed int
(4) unsigned int
can u tell me what is the exact answer from the above option

Im unsure of how to clear break points using dbx v7.2.1
Ive tried using
delete linenumber of breakpoint
however this does not seem to work. Could anyone point me in the correct direction ?

Hi, all:
I am using the KGDB to debug my own network driver on linux. But I suspect if my KGDB work nomally. When I set a breakpoint at "do_one_initcall" function, the kernel function that will call my driver module, and continue to reach there, the "step" command of GDB cannot enter into my... (3 Replies)
