Hi,
I'm trying understand PCIe hot-plugging and surprise removal as
supported in kernel. I am using a board having Ibex Peak. Can someone
please help me understand -
1. Which is the relevant driver for pcie hp for this board? (looks
like pciehp but I see others as well - shpchp)
2. Is there a specific user-space utility for safe removal of PCIe?
Seems like it should be something like - quiesce, unbind, power-off.
3. Is there any existing driver which supports PCIe surprise removal?
Also, when pcie slot has been powered off (as in handle_suprise_event()
in pciehp), how is the driver notified about it?
Thanks,
_nishank
