Hello Sir, thanks for this video. Could you explain lockdep?

[@profdurgahere9007]

Fabulous explanation Sir.

[@ShriramVasudevan]

Thanks

[@raghumgh]

Spinlocks are indeed busy wait but with preemption being enabled if the lock is unavailable

[@a096170311525]

Nice explanation. Can you please add more details on when exactly one should use spin lock or mutex. And why spinlocks are preferred over mutex in interrupt context ?

[@ShriramVasudevan]

Sure will be done..

[@jankeshchakravarthy9389]

hi - very nice and clearly explained video. What is test and lock? how it works? What is the assembly instruction equivalent to test and lock in x86 or ARM controller?

[@MrGeorge1896]

To give a real world example of an x86 code sequence:
movb $1, %dl
.L8:
movl %edx, %eax
xchgb Get_Lock(%rip), %al
testb %al, %al
jne .L8
It is important to know that xchg is an atomic instruction, which can not be interrupted.

Please do programing in detail for all the ipcs

[@parsishashank]

Hello sir,
It will be good if you covered semaphore as well

Will do that as a quick video semaphore vs mutex vs spin lock

Thank you:)

[@sakkamouid3343]

I don't like reading a text from google. If you wrote example of little simple programs and discussed them while applying those concepts would be a lot better to explain to people!
