DESCRIPTION: Sustained kink oscillations in coronal loops have long been ob
 served in TRACE\, SDO/AIA\, and more recently in SolO/EUI images. Although
  their properties are quite well-known now\, their driver and excitation m
 echanism remain under active debate. In this talk I will give an overview 
 over the different ideas/theories that discuss the role of photospheric dr
 iving in the generation of kink oscillations. We exploited an unique datas
 et of high-resolution coronal and photospheric observations taken recently
  by SolO/EUI/HRI and the Swedish 1-m Solar Telescope (SST) respectively du
 ring a dedicated coordinated campaign run in October 2023. Using the SST/C
 RISP data we estimated and quantified the strength of photospheric driving
  at the footpoints of active region coronal loops\, that include pore\, pl
 age\, enhanced-network and sunspot regions. We then looked at kink oscilla
 tion signatures in the same coronal loops within the EUI/HRI coronal image
 s. An attempt was then made to link the photospheric and coronal results t
 ogether. I will finally discuss the implications of this work on the drivi
 ng and excitation mechanism of kink oscillations\, and future perspectives
