Hi,

Sometimes we could hotplug a PCIE device, which require more MMIO
resource than that reserved by BIOS.

My question is: is there a way for kernel to reserved more MMIO
resource for a PCIE-hotplug-capable slot? I searched the
kernel-parameters.txt, but didn't find any related information.

Thanks,
Forrest

If you need 32-bit MMIO, no, because it requires chipset-specific 
reprogramming.  64-bit MMIO should be readily available.
