How to display memory zones content on IDA Pro?
Once the IDA debugger started, I would like to be able to type a memory address (or a memory zone) and look easily at the content of it (in various format). With gdb you would do print /x *0x80456ef or, if you want a wider zone, x /6x 0x80456ef.
How does IDA get the stack trace information?
Double clicking on a line jumps to the exact address of the instruction realizing this call. Currently, IDA uses the EBP frame pointer values to gather the stack trace information. It will fail for functions using other methods for the frame.
What does address mean in hex IDA Pro?
This addressing mode refers to memory relative to the next instruction (not the current, because RIP points to the next instruction). If you do the math, you will see that 0x0062D15A + 0x009360C7 is 0x00F63221. To refer to bbb, you need to calculate 0x00F6322D – ( 0x0062D15A + 7 ).
How to change the base address in Ida?
Copy the address of that instruction from assembly view. Go to “CPU” tab in x64dbg. Press Ctrl + G in x64dbg and enter the address which you want to see. This procedure changes the base address of the loaded binary in IDA according to x64dbg.
What do you need to know about address range mirroring?
Any mirrored memory must be associated with the following attribute. Although the scope of this specification is to support Memory Address Range Mirroring, the above UEFI scheme can also be used to expose Total Mirrored Memory to the OS.
Where do I find mirrored memory in EFI?
Partial memory ranges that are set to be mirrored are indicated by the Attribute field in the EFI_MEMORY_DESCRIPTOR. Any mirrored memory must be associated with the following attribute.
How is memory mirroring used in a server?
Memory mirroring is a technique used to separate memory into two separate channels, usually on a memory device, like a server. In memory mirroring, one channel is copied to another to create redundancy. This method makes input/output (I/O) registers and memory appear with more than one address range…
How many memory references are needed for top down traversal?
Note that the top-down traversal requires as many memory references as there are table levels, plus one more to get the actual data, and this number grows as the virtual address grows (as depicted in the Alpha’s table, Figure 31.3 ).
When does a TLB miss only require one memory reference?
Once this user PTE is loaded into the TLB, the user table handler ends and the faulting user-level load or store is retried. Usually, however, the first PTE lookup—the user PTE lookup—succeeds and then a TLB miss only requires one memory reference to translate the faulting user address.
How are memory references used in prefetching software?
Most software prefetching in practice focuses on array references performed within loops that give rise to regular memory-access patterns. These memory references employ array subscripts that are affine, i.e., linear combinations of loop index variables with constant coefficients and additive constants.
