Re: Live patching on ARM64

Hi Madhavan,

I'd also recommend subscribing to the live-patching mailing list (Cc'ed).

Hi all,

My name is Madhavan Venkataraman.

Microsoft is very interested in Live Patching support for ARM64.
On behalf of Microsoft, I would like to contribute.

I would like to get in touch with the people who are currently working
in this area, find out what exactly they are working on and see if they
could use an extra pair of eyes/hands with what they are working on.

It looks like the most recent work in this area has been from the
following folks:

Mark Brown and Mark Rutland:
	Kernel changes to providing reliable stack traces.

Julien Thierry:
	Providing ARM64 support in objtool.

Torsten Duwe:
	Ftrace with regs.

I apologize if I have missed anyone else who is working on Live Patching
for ARM64. Do let me know.

Is there any work I can help with? Any areas that need investigation, any code
that needs to be written, any work that needs to be reviewed, any testing that
needs to done? You folks are probably super busy and would not mind an extra
hand.

I have subscribed to linux-arm-kernel. But if any discussions should happen on
another mailing list, could you please CC me? Appreciate it.

Thanks! I look forward to working with you.

Madhavan

P.S.:

Julien,

Could you send me a link to your latest RFC submission? Thanks!
