Of course, some of kernel's modules might run in user-mode, but it will be ok I think.<br><br>Thanks for your reference, I'll take a look at it. <br><br>Also, I found out that ARM supports OS awareness in their DS-5 debugger. They have a mechanism for adding new operating systems. All you need to do is to describe OS' model (thread's or task's structure for example). I think that is how it might be done in LLDB.</div></div></div><br><div class="gmail_quote"><div dir="ltr">On Wed, Oct 31, 2018 at 9:26 PM Leonard Mosescu <<a href="mailto:mosescu@google.com">mosescu@google.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi Alexander, are you interested in user-mode, kernel-mode debugging or both?<div><br></div><div>Fore reference, the current state of the art regarding OS-awareness debugging is <a href="https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/index" target="_blank">debugging tools for windows</a> (windbg & co.).

The one of my possible diploma themes is "OS Awareness in LLDB". Generally, the OS awareness extends a debugger to provide a representation of the OS threads - or tasks - and other relevant data structures, typically semaphores, mutexes, or queues.<br><br>I want to ask the community if OS awareness is interesting for LLDB users and developers? The main goal is to create some base on top of LLDB that can be extended to support awareness for different operating systems.</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small;color:rgb(0,0,0)"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small;color:rgb(0,0,0)">Also, if you have a good article or other useful information about OS awareness, please share it with me.<br><br>Thanks in advance!</div><span class="m_-3812305988982444733HOEnZb"><font color="#888888"><div><br></div>-- <br><div dir="ltr"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div><span style="color:rgb(0,0,0);font-family:arial,helvetica,sans-serif;font-size:12.8px">Alexander</span><br></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></font></span></div></div>
