Thunderbolt MSI interrupts limitation

Hi everyone,

I would like use 32 MSI numbers for my PCI device that connected via Thunderbolt on Windows 10 x64.
But Windows always allocates only 16 MSI for my device.
I also found, that Thunderbolt controller has limitation maximum 16 MSI numbers.


How can I increase limitation of MSIs numbers for Thunderbolt controller? - hope, it will help me get 32 MSIs for my device, at least just for test.

Does Thunderbolt have some limitation for MSIs numbers in Windows 10?
