memory dump

memory dump

[Marc Leeman]

A quick question:

Can I obtain the memory location of kernel variables based on the
System.map file in such a way that I can dump them with a BDI probe.

dump 0xabcdef 0x10000 dump.txt

Yes. Just "grep" for the symbol in System.map and subtract KERNELLOAD
resp. CONFIG_KERNEL_START (0xC0000000); for example:

	-> grep log_buf System.map
	c017c754 b log_buf

Use: "dump 0x0017c754" to dump the contents of the log buffer.
